Ruminant Farming and Post-Mining Reclamation

To fertilize post-mining soil, organic matter or compost is important and much needed. Land or post-mining land is damaged with a very low fertility level so it needs to be processed (treatment) first before it can be planted. The choice of plants depends on the purpose of using the post-mining land, whether for agriculture, forestry or others. Planting fast growing trees and short rotation coppice i.e. legume group trees is the best option. In addition to the ability to survive, its deep roots are also able to withstand erosion and the ability to symbiotic with azetobacter so that it binds nitrogen in root nodules so that it fertilizes the soil. And furthermore, the legume tree can be used as a source of animal feed (the leaves), bioenergy (the wood) and honey (the flowers).

The creation of livestock and their supporters such as forage plantations is like an ammunition factory to reclaim the post-mining land. The wider and faster the target time for reclaiming the land, the larger the farm required. Ruminant farms with thousands or even tens of thousands of livestock can be made with this purpose. Although the main objective is to produce compost for post-mining land reclamation, the indirect benefits from the farm are no less large. Even from the farm business can get big financial benefits. The main and common problem faced by mining entrepreneurs is that they are reluctant to do reclamation because it costs a lot and does not provide financial benefits. But when the reclamation activity does not reduce the company's finances even provide large profit, of course it will be a different story. The volume of mining carried out should also be proportional to the repair or post-mining reclamation.

To maximize the reclamation, biochar needs to be used. The use of biochar will make compost in post-mining land not easily lost after being washed by rain, maintain soil moisture because biochar is able to hold water (water holding capacity), raise soil pH so that soil microbial activity is more optimal and more nutrients are absorbed by plants, and biochar also will become a home or colony for soil microbes so that it will further fertilize the soil. Meanwhile, in terms of climate change mitigation, the use of biochar in the soil will also store carbon (carbon sequestration) for a very long time, up to hundreds of years. Carbon credits with a carbon sink mechanism as part of the CCS (carbon capture and storage) application can also be obtained. The carbon trading market is predicted to get bigger as global awareness of climate change and biochar as one of the solutions are also increasingly being applied, discussed and paid attention to by the earth's population.

The extent of post-mining land that reaches millions of hectares, the high demand for domestic meat as well as the export market, and the large amount of biomass waste that can be converted into biochar, post-mining reclamation should be a priority for mining entrepreneurs moreover, the reclamation activity does not reduce the company's profit but instead gives more profits. If this can be done, the environmental damage caused by mining can be minimized. Indeed, humans need various products that come from the mining to make their lives easier, but also not to the point that on the other hand the mining business actually damages the environment which will lead to disasters in the future.

Chemical Fertilizer Plant, Blue Hydrogen, Blue Ammonia and Ruminant Farms

As a comparison of the sheep population in New Zealand with people population of 3 million, the number of sheep is 5 million, then Australia with people population of 25 million, the total population of cattle is 26 million while Indonesia with people population of 270 million, the total population of sheep is less than 50 million, moreover the cattle population is also confirmed much smaller. This indicates that the ruminant livestock sector is not yet a business or industrial engine for economic growth. Whereas in addition to natural resources that support, the need for meat and fertilizer needs for agriculture is also very large. When the ruminant livestock sector is optimized, apart from being self-sufficient in meat as a source of animal protein, it can even be exported, and it will also promote agriculture because the manure is turned into organic fertilizer. This organic fertilizer has many advantages over chemical fertilizers, including not destroying the physical and chemical properties of the soil, activating soil microbes and providing complete nutrients. When the livestock sector is optimized, it is also very likely that it will replace the use of chemical fertilizers or other languages ​​as well as self-sufficiency in fertilizers so that chemical fertilizer plants close or stop producing. The integration of livestock and agriculture will create food sovereignty, an extraordinary achievement if it can be realized.

To save the chemical fertilizer plants, it can be converted into a plant or energy producer in the form of blue hydrogen or blue ammonia. Natural gas, which is a fossil fuel and is the raw material for chemical fertilizers, is separated from the carbon elements so that hydrogen is obtained. Carbon dioxide (CO2) gas that has been separated from natural gas is then captured and stored (CCS = Carbon Capture and Storage) so that it is not released into the atmosphere. And because the raw material for hydrogen fuel comes from fossil fuels, it is called blue hydrogen, whereas if it comes from renewable materials such as biomass, water and so on, it is called green hydrogen. So it can be said that blue hydrogen is still half fossil because the raw materials are from fossil sources and green hydrogen is already 100% from renewable sources. Hydrogen compounds or hydrogen gas have atomic bonds in the form of two hydrogen elements (H2) as a stable compound in nature, and to increase the energy of hydrogen gas, ammonia (NH3) can be made, namely with three hydrogen bonds. Just like the term blue hydrogen above, when the ammonia comes from fossil fuels it is called blue ammonia and when it comes from renewable materials it is called green ammonia. Japanese companies have even made power plants (generators) that use 100% as fuel, for more details read here.

Efforts to boost the livestock sector by integrating with the agricultural sector is not an easy thing. The factors of market access ability, farming techniques, provision of feed, management and livestock business are a number of things that hinder the realization of the vision of food sovereignty. Especially for innovations so that they can be competitive at the international level. Motivation factors, low willingness, low reading and learning culture, lack of friendship for networking, government alignments with policies for less carrying capacity, and so on also hinder on the other hand. But with abundant natural resources potential and strong will, these obstacles should be overcome, especially ruminant farming, especially sheep and goats, is also highly recommended in Islam so that as a Muslim should be more motivated. There is almost no one when doing any kind of effort, let alone to realize a big idea without a hitch, because that is the sunatullah.

Utilization of Marginal Land and Former Coal Mines for Ruminant Livestock and Charcoal Briquette Production

The extent of marginal land including critical land and unused land which reaches more than 6 million hectares as well as ex-coal mining land which is estimated to reach 8 million hectares are environmental problems that must be overcome. Turning these lands back into productive land so that apart from preventing a bigger environmental disaster, it also provides other benefits for human life. One solution to this problem is to plant the land with pioneer plants of the leguminoceae group whose roots firmly grip the soil and are in symbiosis with azetobacter so that it fertilizes the soil such as calliandra and gliricidia as well as its leaves as a source of animal feed, flowers for honey production, and the wood for the production of charcoal briquettes. Or in other words, the establishment of the plantation besides having environmental benefits as an effort for conservation and land reclamation along with water conservation, of course, also provides benefits for ruminant livestock or the production of animal feed and the production of charcoal briquettes. Ruminant farms, namely sheep, goats and cattle, are very suitable to be developed using the leaves of the plantation. The combination with charcoal briquettes, namely by using the wood, is an ideal combination or integration. In a number of countries the charcoal briquettes are used as fuel for grilling BBQ from lamb, goat and beef. So in addition to all parts of the tree can be utilized also even the final product of livestock in the form of meat and wood processing so that it becomes charcoal briquettes also meet again. An interesting and unique blend or integration.

The need for red meat, namely lamb, goat and beef in the country itself is still lacking, so it requires an adequate supply. In terms of goat and lamb meat, the need for the Jabodetabek (Jakarta, Bogor, Depok, Tangerang and Bekasi) area alone has not been met, so it is supplied alternately from East Java, Central Java and Lampung alternately. In addition, according to Aspaqin (Association of Indonesian Aqiqah Entrepreneurs) there has been an imbalance in the supply of sheep and goats due to the large number of female productive sheep and goats being slaughtered. This condition causes the sustainability of the supply of sheep and goats to be disrupted. According to data from Aspaqin that they collected, 63% of female sheep and goats were slaughtered from a total of 331,693 slaughtered tails. Of course there are still many who are not recorded because there are still many aqiqah entrepreneurs who are not members of the Aspaqin. In addition, there are also many stalls for eating goat dishes, such as satay stalls which still slaughter productive sheep and female goats. Aspaqin continues to strive for education and socialization to improve these conditions, including a proposal to provide punishment for the slaughter of these productive females.

Meanwhile, in the beef cattle sector, Indonesia has the advantage of fattening cattle (feedlot). With the availability of a lot of agricultural wastes and agro-industrial wastes in Indonesia, this business is very competitive, even indonesia is the best. Moreover, this is by creating a plantation that is specifically designed for the feed source by utilizing land that can be said to be unproductive at first. By only taking about 100-120 days, the fattening was successful or completed, although in general, breeder or seed cattle are generally still imported from Australia. Australia, especially northern Australia is the center of the seed cattle. With the vast grazing area there, the cost of producing feeder cattle is very competitive and cannot be done well in Indonesia. Although there are a number of discourses to produce seed cattle in eastern Indonesia and palm oil plantations, the facts are still not or are still very minimal. In addition, according to Gapuspindo (Indonesian Beef Cattle Farmers Association), the domestic demand for beef has not been met or there is still a shortage of around 60% and this shortage is filled by imports of buffalo meat from India. Buffalo meat from India actually has to be sold cheaper than beef, but in fact it is the same as beef. This condition is getting worse, especially in the period leading up to the Eid al-Fitr holiday with lots of illegal meat circulating, such as wild boar meat.

Charcoal briquettes are a product of wood processing from the plantation. The production of charcoal briquettes using wood raw materials must also be managed properly so that it can be sustainable. The important thing to note is that the harvest of wood for the production of charcoal briquettes should not exceed the production of wood from the plantation itself, for example the need for wood for the production of briquettes is 1000 tons / month, the speed of wood production from the plantation is at least the same as the wood harvested every month. Charcoal briquette production techniques are also available in 2 options or routes such as the scheme below. However, route 1, which is briquetting before carbonization, is more in demand because the quality of the briquettes produced is better. In this route, the wood biomass raw material has been downsized so that the particle size is suitable for the production of the briquettes and the dryness level has also been adjusted and then briquetted or pressed in a briquette machine without using additional adhesive. The briquette product is then carbonized so that it becomes the final product in the form of charcoal briquettes or commonly known as sawdust charcoal briquette.

In addition to domestic consumption, sheep and goats are also export commodities to a number of countries. Information obtained from the Ministry of Agriculture's Pusdatin (Centre of datas and informations) that Indonesian sheep and goats have been exported, among others, to Malaysia and the United Arab Emirates (UAE). Basically, the choice to do sheep and goat export business is the choice of the breeders or farmers  themself and the specifications for the export market are also different for local needs. If the local market generally uses sheep and goats weighing 25-35 kg per head, the export market generally requires a weight above 35 kg per head. For example, for a large market for sheep and goats, Saudi Arabia, especially during the hajj season, reaches around 2 million heads or a quarter of the country's needs, which means it reaches 8 million heads per year.

And lastly, basically the need for food, especially animal protein and more specifically from ruminants sheep, goats and cattle will continue to increase along with the increase in the population itself. The world population is estimated to reach 10 billion in 2050 or 1.3 times today and Indonesia's population will reach 319 million in 2045 or 1.2 times from today. Another thing that deserves attention is Indonesia's demographic bonus. The demographic bonus with the dominance of the productive young generation should be a separate strength for the Indonesian nation if it is supported and directed properly. This sector is certainly one solution. With the vast land area in Indonesia that can be used for this business, God willing, it will overcome various important problems today such as food security, preventing environmental damage, creating jobs, improving living standards, improving food quality and so on.     

Energy Plantation in Coal Mine Reclamation, Wood Pellet Factory and Coal Powerplant Cofiring in Indonesia

The extent of ex-coal mining area which reaches around 8 million hectares is an environmental problem itself that needs to be addressed. Energy plantations are an effective solution for the reclamation of the former coal mine land for more details, you can read here. Reclamation of ex-coal mining land is a form of responsibility of the coal mining company. Reclamation should be carried out as well as possible, not only symbolic and ceremonial, so that the effects of environmental damage can be minimized. Efforts to reclaim ex-coal mining land is not an easy thing and requires a lot of time and money, so it is not surprising that many avoid this responsibility. The best solution is to tackle the problem while generating both economic and environmental benefits. The production of wood pellets with wood raw materials from the energy plantation is a surefire solution to overcome this environmental damage as well as economic benefits.

Recently, the government launched a cofiring program for a number of coal powerplants in Indonesia. In 2020 the cofiring program has been initiated with a target of 37 coal powerplants and by the end of 2020 it has been reported that 20 coal powerplants have been implemented. While in total there are 114 units of coal powerplans owned by PLN (Indonesia state owned electricity company) that have the potential for cofiring spread over 52 locations with a total capacity of 18,154 megawatts (MW) with a target completion of 2024. Consisting of 13 coal powerplant locations in Sumatra, 16 coal powerplants locations in Java, Kalimantan (10 locations), Bali and Nusa Tenggara (4 coal powerplants unit), Sulawesi (6 locations) and Maluku and Papua (3 coal powerplant locations). Meanwhile, the cofiring ratio ranges from 1-5% of biomass with an estimated biomass requirement of 9-12 million tons per year. Cofiring is the easiest and cheapest effort for coal powerplant to gradually use renewable energy, especially biomass with main purpose of CO2 reduction. Currently, there is also a national standard for wood pellets (SNI wood pellets) for the purposes of cofiring and for more details, please read here. The use of biomass fuels, especially wood pellets, is a carbon neutral scenario that needs to be continuously improved. The biomass fuel will save the environment and not increase the earth's temperature, for more details read here.

Policies to reduce the consumption of fossil fuels, especially coal, also continue to be carried out globally. For Asia, for example, Japan and Korea with their leading Feed in Tariff and Renewable Portfolio Standard (RPS) in the use of renewable energy, especially wood pellets. While in Europe with the Renewable Energy Directive II (RED II) renewable energy is targeted to reach 32% by 2030, biomass fuel is predicted to account for around 75% of the portion of renewable energy and the target is that coal is not used in total by 2050. Germany announced not to use coal in 2038, the UK even targets to no longer use coal for electricity production starting in October 2024. North America, namely the United States and Canada as members of the G7 are also committed to reducing coal consumption, even Canada in 2018 announced regulations to no longer use coal for electricity generation by 2030. On the other hand, the construction of coal power plants financed by China in various countries has failed. In addition, the G7 countries (Canada, France, Germany, Italy, Japan, Britain, and the United States) have been aggressively blocking the use of coal. Countries that still support coal use, such as China and Indonesia, are increasingly isolated and could face more pressure to stop the activity.

Leaves as a by-product of the energy plantations have the potential to be used as animal feed. The leaves of this type of legume have a fairly high protein content. The quantity of leaves produced is also large, proportional to the area of ​​the energy plantation. Ideally, the development of energy plantation will support the livestock industry, so that not only energy needs are met but also food needs. As a comparison, the European animal feed producer association, FEFAC, prioritizes protein sources for animal feed from rapeseed energy plantations from a number of efforts to obtain protein sources for animal feed, for more details please read here. The main products of rapeseed energy plantations are oil which is used for biodiesel production, and meal as a by-product of the oil production which is used as a source of animal feed protein. The need for protein sources for animal feed has an important role as nutrition for livestock, especially ruminants. Europe is still very shortage of these protein sources so that imports cannot be avoided. It is estimated that around 48 million tons of feed protein sources are needed by Europe, so there is a chance that leaves from energy plantations can be exported to Europe for this. When the domestic feed industry has not been able to absorb it, export is the best choice.

Planning Long-Term Feed Supply

Feed is the highest cost component in animal husbandry with a share of about 70%. Thus, feed has an important role for the sustainability of the business. Planning in the provision of good feed will reduce the risk of failure, including a decrease in the production of these farms. Maintaining the high performance of the livestock industry is not an easy thing, of course, including maintaining the quality and quantity of the feed. Feed planning for long-term supply needs to be done carefully and comprehensively so that livestock business can be optimal. Seasonal factor is an important factor in the availability of the feed. The success rate and the amount of profit earned can also be predicted better.

In commercial business, ruminant feed, especially sheep, goats and cattle, is generally easier to obtain than poultry or chicken feed. Imports of soybean meal have been carried out for the poultry or chicken feed. Chicken meat is still ranked 1st as a source of animal protein in Indonesia with a portion of around 70%. Whereas for the ruminants above, generally the feed can be provided by local food sources such as grasses and legume plants. But along with the narrowing of the land that can be used for forage crops, the more limited the availability of feed for livestock, especially for pasture. This condition makes it difficult for ruminant farms to be developed in large capacities or industry-oriented. Energy plantations with an area of up to thousands of hectares are expected to be a solution for this.

The development of energy plantations itself is closely related to the use of renewable energy, especially biomass, both locally / domestically and globally. In line with the bioeconomy era, the use of fossil fuels as well as for the manufacture of various other products is reduced, so biomass will receive more attention and will be increasingly used. This should be in line with the growth of the ruminant livestock sector and the halal industry in general. Related to animal feed, there are 3 important things that need to be considered, namely nutrition, safety and sustainability. Apart from these factors, technological, logistics and good management factors also play an important role in the long-term sustainability of the feed supply. If all the elements of feed (fiber, protein, vitamins, minerals, etc.) can be fulfilled from local / domestic sources so that the price is cheaper, the livestock business will be more competitive. Meanwhile, if it depends on imports, the cost of feed will be expensive and the livestock business will be less competitive so that the output of meat and milk products as a source of protein will also be expensive. And don't let the domestic animal feed production grow, say 5 times but imports of raw materials 15 times.

Modern Ruminant Livestock Paradigm: Reducing Methane Production and Increasing Feed Efficiency

The gases in the atmosphere that can capture the sun's heat are called greenhouse gases (GHG). Which includes greenhouse gases in the atmosphere, among others, are carbon dioxide (CO2), nitrogen dioxide (N2O), methane (CH4), and freon (SF6, HFC and PFC). Methane gas (CH4) is a dangerous gas for the earth's atmosphere and one of the greenhouse gas groups above because of the destructive power of methane gas 21 times carbon dioxide (CO2). This requires efforts to prevent methane gas and reduce its production. An example is the use of POME waste or palm oil mill effluent for biogas production. In this way, methane occurring in the open air (aerobic) will be avoided (methane avoidance scenario) and will not be released into the atmosphere with the biogas unit. The livestock sector also has the potential to produce, namely the group of ruminant farms or ruminant animals. The methane is produced in the ruminant's rumen as part of the digestion process. It is estimated that the contribution of methane from ruminant livestock is dominant and of course it needs to be reduced. The production of methane gas (CH4) besides being an environmental problem also causes a lot of energy loss in livestock. And it turns out that there is a process of reducing methane production which simultaneously improves health and increases body weight and milk production.

Large ruminant farms should be more aware of this condition and have a greater incentive to reduce methane production. Biochar is a feed supplement that can be used for the above purposes. The use of 1-3% biochar from dry feed ingredients has been shown to significantly increase body weight gain in beef cattle, as well as milk production in dairy cows. Experiments in Australia on beef cattle for 2 months have given a weight gain of 10% compared to those who do not use biochar. As for dairy cows, it has provided a profit of $ 70,000 per year. For more details, read here. Meanwhile, the reduction in methane gas emissions is estimated at 29% from the use of biochar. Once paddle 2-3 islands, so the saying goes.

Another effect of using biochar as a feed additive is that livestock manure becomes denser and less smelly. Biochar can also be used alone to deal with the smell and viscosity of livestock manure, so that the cage becomes cleaner and does not smell strong. In addition, if the manure is used for production, the biogas production will also increase, for more details, please read here. The composted digestate will also produce better organic fertilizer (compost) because of the additional biochar.

The quality of biochar is also very important, especially for animal feed supplements. Meat and milk are livestock production to meet human food needs, so that it will also affect humans in the end. The quality of biochar is determined by the raw materials used and the production process carried out. This indicates that not all biochar has the same quality, for example biochar from agricultural wastes with high ash content with traditional processes, with wood biomass raw materials with a small ash content and modern processes, of course the results are different, for example using the same modern technology will have different results. The differences mainly lie in their physical chemistry properties.

Biochar production should also be designed according to its objectives, for example the biochar feed supplement above must use selected biomass raw materials and modern processes so that the quality is stable and maintained. Meanwhile, the reference for biochar quality can be OMRI, USDA or IBI. World feed livestock associations or organizations such as FEFAC, IFIF and AFIA are currently very concerned about safety and sustainability, so this can be in line with biochar as a feed additive. Biochar as a feed additive, especially dairy cattle, has been accepted by almost all European Union countries. Meanwhile, for purposes such as reducing odors and the dilution of impurities, biochar is produced from any biomass and even by using simple technology (low tech).

Learning the History of the World Animal Feed Industry

The ability to create a stable supply of food from livestock led to the world's population developing, community centers developing and cities emerging. The domestication of wild plants and livestock, as well as the use of irrigation and tillage tools, has resulted in a growing population. When the human population is increasing and many people live in urban areas, livestock and agriculture are increasingly organized, efficient and productive with the use of technology and various innovations. The science of animal feed nutrition became a scientific discipline starting about 200 years ago. In 1810 the German scientist Albrecht Daniel Thaer developed the first animal feed standard by comparing the nutrients of different types of hay. This was followed by a number of discoveries related to animal feed nutrition such as proximate analysis systems, feed standards based on digestible nutrients, vitamins and minerals needed by livestock, until 1944 L.A. Maynard published a table of nutritional needs for livestock and laboratory animal husbandry. The table of nutritional requirements then becomes the world standard for feed formulation to date including ruminants such as sheep, goats and cows.

Animal feed into a trade commodity or commercial product began in the early 1800s when the means of transportation and moving agricultural products mainly used horses and donkeys. Horse farm and breeding is an important thing. Horse stops as resting places are made along the route between cities as public facilities or similar to gas stations at this time. One of the important things in this resting place is the provision of quality feed for the horses, such as hay, seeds and so on. This has sprung up a number of businesses providing horse and donkey feed, and a number of feed companies that exist today such as Cargill, ADM, Purina, and Ridley started here, even though at that time the use of scientific feed formulations was very minimal.

Horse stopping and feeding station in the 1800s

 

Feed mills in America are built adjacent to grain mills, even many industries have been engaged in grinding the grain is also involved in the feed industry. The animal feed industry uses by-products or waste from grinding these grains. The first animal feed mills were made by adding a number of nutrients to the byproducts of wheat flour. The use of technology and mechanization is also increasing in number to achieve feed products with uniform quality and efficient production processes. Around 1900 the hammer mill was first used followed by the horizontal batch mixer in 1909. The early 20th century saw many advances in the use of technology for animal feed but the most noticeable and dramatic progress was when Purina introduced feed pellets in the 1920s. With this pelletization, the powder is less favorable to livestock (unpalatable), the different densities become easier to use and increases uniformity. This pelletization technique was quickly in demand by many feed producers so that in 1930 there were a number of feed factories that specialized in the production of these feed pellets.

Around 1940 and 1950 the formulation of feed was more complex with the addition of vitamins and minerals. In the late 1950s progress and specialization continued in the feed industry. In addition, the production capacity is also getting bigger, even in the 1970s the range of animal feed factory capacity was between 200 - 500 thousand tons per year. Meanwhile, large farms choose to make their own feed to make it more competitive. The use of automation in feed mills began in 1975 and continues to evolve to minimize feed costs and maximize efficiency in the production process. The technology and software for the production process continue to develop, including the logistics of various feed ingredients, size characteristics, the pelletization process, the extrusion process, and many other things in production.

Meanwhile, the development of the animal feed industry in Europe is more or less imitating the existing development pattern in America. Grain processing and milling technology advanced rapidly in the 19th century. In an effort to accelerate the development of the animal feed industry in Europe, in 1959 Belgium, France, Germany, Italy and the Netherlands formed the European Feed Manufacturers' Federation (FEFAC) as an organization for the feed industry in Europe. FEFAC has a mission to unite the feed industry and establish communication and cooperation in the European region. Even though it was quite successful in this effort, FEFAC experienced quite horrendous problems, namely in 1996 with the Bovine Spongiform Encephalopathy (BSE) crisis because it was related to feeding derived from mammalian meat and bone meal (MBM) or bone meal and mammalian meat for ruminant feed. Meat infected with BSE causes Creutzfeldt-Jakob disease in humans, which creates a high risk to the human food chain. After the outbreak spread, the use of MBM in animal feed was prohibited. This regulation causes a high dependence on imported raw materials such as soybean meal for a sustainable supply of meat, milk and eggs. Learning from this, FEFAC in the 21st century has a focus on feed and food safety initiatives. The organization took initiatives to be globally enforceable, such as in 2001 banning the use of MBM, in 2006 banning antibiotics in feed, legislation related to nitrates in livestock manure, and the use of GMO raw materials (GMOs).

Brazil is a country in South America that is quite developed in the animal feed industry and is currently the third largest supplier of animal feed in the world. Interestingly, commercial feed production in Brazil was only practiced in the 1960s. The development pattern of the animal feed industry in Brazil uses the same model as in America and Europe, namely the companies involved in milling and processing grains such as wheat and maize were also the first to be involved in the animal feed industry. The first wheat bran was built in the 1940s. Currently in Brazil, part of the feed industry is integrated with its livestock, or about 80%, which means that the feed manufacturing industry is also the same industry as the livestock. Another interesting thing is that Brazil also ranks second in the world for the pet feed industry, even though this industry was almost non-existent before the 1990s. Brazil has abundant production of maize, soybeans and other commodities which greatly support the animal feed industry.

China is the largest animal feed producer in the world, accounting for nearly 20% of the world, followed by the United States (17.4%) and Brazil (6.8%). The history of the animal feed industry in China began in 1930 with the first modern flour mills established and was followed by the use of the mill's by-products for animal feed. Meanwhile, the first modern feed factory was only established in 1949. Furthermore, due to the political uncertainty and slow economic growth and the centralized government, grain production decreased so that most of it was for human consumption. The growth of the feed industry and livestock is also very limited. Changes in political conditions in 1976 made the animal feed industry begin to grow again. In 1977 a comparative study was conducted on the feed industry in France, Japan and America. And in 1984 a draft plan for the development of the feed industry was published with outlines of objectives and strategies for the years 1984-2000.

In the same year (1984) a number of policies were also issued to support the development of the domestic feed industry, such as high export taxes for feed ingredients and milling equipment, tax free for up to 3 years for new feed factories and even tax free if the factory was not yet producing with sufficient profit. The first feed standard was issued in 1996, but due to inconsistent interpretation of the standard, nearly 10% of animal feed tests were substandard in 1998. Even in 2007 there was a withdrawal of pet feed due to contamination with melamine and cyanuric acid (which is high in nitrogen and identified as a crude protein content) in protein elements that cause kidney failure. The use of nitrogen from the above chemical is also carried out on agricultural products as well as the withdrawal of agricultural products from China in South Africa, the European Union and the United States. Even America ordered the USDA to inspect all agricultural products from China. In 2008 and 2009 China focused on eliminating the problem of counterfeiting or mixing and the effects of the resulting crisis. In 2010 a revised version of the feed and feed additive regulations was published to further ensure quality and safety. Although China is the largest feed producer in the world, the need for feed raw materials still relies on imports, especially soybean flour / meal to support food needs in the form of meat, milk and eggs for around its 1.3 billion people.

The source and availability of feed has always been the main orientation for livestock business. From the above history it is clear that large farms were always built close to a source of feed such as mills. The role of the government is also very important to encourage this effort. The high price of factory-produced concentrate can also be a driving force for the growth of large farms adjacent to energy plantations. The protein element in feed, apart from being essential, is also the highest cost element, while feed itself holds the highest cost component in animal husbandry or around 70%. Ruminants are herbivores so their food comes from plants, the case of MBM in Europe can be an expensive lesson that feeding from mammals actually creates new problems. Moreover, if the food category is najis/unclean, then the livestock become jalalah animals which are prohibited from being consumed (haram). Meanwhile, the case of mixing with dangerous chemicals that occurred in China with melamine and cyanuric acid was only to deceive the protein content so that it looks high is also dangerous for the health of the human body.

The momentum of the energy plantation or biomass plantation can be a great momentum for the growth of the ruminant livestock industry as long as it is well prepared. Other feed sources can be obtained from the surrounding environment so that the complete feed composition can be fulfilled. Bran from rice mills are also not difficult to find in Indonesia because the staple food of the majority of Indonesia's population is rice. Rice fields for rice farming are almost everywhere, so are the rice mills. Other sources of grasses such as elephant grass, benggala grass and so on as a source of fiber or agricultural wastes such as straw, peanut leaves, corn leaves and stalks and so on can be done by empowering the surrounding community. And when the feed production is sufficient for their own needs, the excess feed production can be sold elsewhere.

Production of Box Shaped Hay From Gliricidia Leaves

Apart from market, feed is another important factor in livestock business. Striving for and ensuring the availability of feed throughout the year both in quality and quantity is a challenge in itself, especially industrial-oriented ruminant farms. The productivity of livestock products is largely determined by these feed factors. The important role for livestock is for the growth of young livestock and for maintaining life and producing products (milk, calves/lamb, meat) and power for adult livestock. Another function of feed is to maintain endurance and health. In order for livestock to grow as expected, the type of feed given to livestock must be of good quality and in sufficient quantities.

In addition, livestock productivity itself is influenced a lot by environmental factors, namely up to 70%, while about 30% is genetic factors. And among these environmental factors, the aspect of feed has the greatest influence, which is around 60%, for example superior sheep farming such as the dorper type but if the quality and quantity of feed is not met then the results are also not optimal. Meanwhile, in terms of livestock business, the cost of feed is also the largest production cost, namely 60-80% of the total production cost. So it is very natural that attention or focus on feed issues is very important.

Seeing the above conditions, processing technology for animal feed is important. The purposes of animal feed processing include preserving nutrition and extending shelf life. Drying the leaves of gliricidia or calliandra to a moisture content of about 15% is one such effort or commonly called hay. By making hay the two objectives of processing animal feed above, namely maintaining nutrition and extending the shelf life can be achieved, but with a large volume of dry feed or hay (bulky) it will be inefficient in using space for storage or if it is to be used in other places where need quite far transportation. This is why it is necessary to apply biomass densification technology to solve this problem. Hay compaction into blocks or box shaped is a practical and easy undertaking. The equipment and compaction process into box shaped is also easy and cheap, compared to other biomass compaction technologies such as pellets or briquettes.

A sheep or cow farm should be built near the energy plantation so that they can easily get a source of feed for the gliricidia leaves. The leaves are then made hay and compacted into the blocks / box shaped. And because gliricidia leaves are a source of protein, so to be a complete feed, another source of feed is needed. This can be fulfilled by the surrounding community with community empowerment patterns or for more details, please read here. Sources of feed from the community, for example a source of fiber from grasses or agricultural waste, can also be made hay, so that the farm is available as a complete feed (complete feed) which is safe for the operation of the farm business. And because the estimated leaf production from energy plantations is very abundant, some of the hay that is produced can also be sold elsewhere. 

Technology is basically a tool to achieve a goal. From a technological point of view, namely biomass densification, besides the raw material for glicidia leaves can be made hay, the leaves can also be made into pellets or briquettes. The main difference between pellets and briquettes is only a matter of size, briquettes are bigger than pellets. The form of puck briquettes like the photo above is the best form for animal feed applications. From a technical perspective, pellets and briquettes are also denser or have a higher density than hay. The dust problem in hay can also be reduced by making these pellets or briquettes. But it is true that making pellets or briquettes requires higher investment costs and the production process is more complex.

Complete Feed Production With Integration of Energy Plantations and Community Empowerment

Feed and markets are the two most important things in the world of livestock. Farmers who are able to get safe, nutritious, affordable, adequate and sustainable feed will produce the best quality and quantity. One of the safe categories is not GMO. For more details, you can read it here. It is possible to make these feeds yourself by utilizing the local potential. The expertise to provide feed is of course very important for professional farms. Likewise, broad market access allows the livestock business to be increasingly profitable. The current era of the internet is also very supportive of gaining such broad market access. Social media such as whatsapp groups, telegram, twitter, youtube and so on can be used for this.

To get complete nutrition so that it becomes a complete feed, of course, cannot be obtained from just one source. Malnutrition which results in decreased quality and livestock production will inevitably occur, if the feed nutrition is inadequate. It is possible that the development of an energy plantation or a biomass plantation with leguminoceae plants such as gliricidia and red calliandra is very likely to be integrated with the livestock business. Sheep, goat and cow farms are the best choices for this farming business. It is also hoped that later progress in the renewable energy sector from energy or biomaterial plantations will be in line with the livestock business. While glicidia leaves or calliandra have the main content in the form of protein which can reach 25%, other sources of nutrients such as sources of fiber, vitamins and minerals can be obtained from the environment around the plantation. Communities around the plantation area can be empowered to plant these nutritional complementary crops or take advantage of their various agricultural wastes such as straw, grass and so on. 

The leaves of gliricidia or calliandra as a source of feed are estimated to be a maximum of 30% of the complete feed. With leaf productivity per hectare of around 30 tonnes / wet year or 18 tonnes / dry year. This means that for every 1000 hectares of gliricidia plantation will produce 18,000 tons / year of dry leaves. If a goat / sheep eats 3 kg / day (30% of the total consumption of complete feed), it means that for 1 year 1 sheep / goat consumes about 1 ton of dry leaves or with a volume of 18,000 tons / year means that it can be sufficient for 18,000 sheep / goats for 1 year.

The animal feed innovation must also be carried out so that the conversion of feed to meat product, milk or breed is high, even the feed formulation should be adjusted to the age level of the livestock. Researches to obtain varied feed formulations or recipes, especially those that are adaptive to local potential, are very important. This includes identifying and developing as many feed sources as possible. The more identified feed sources and feed formulations, it is hoped that the livestock business will grow rapidly. Case studies on gliricidia and calliandra leaves have several anti-nutritional substances, so these substances must also be reduced or even completely eliminated so that the feed nutrients are absorbed effectively. Anti-nutritional substances in gliricidia are dicoumerol, HCN (cyanide acid) and nitrates, while red calliandra is an anti-nutritional substance of tannins. 

World Animal Feed Production Approximately 1 billion tonnes / year and Potential Gliricidia Leaf Feed Pellets

World animal feed production is currently estimated at 1 billion tonnes per year. As a chain to fulfill human food needs, especially meat, animal feed production is very important and strategic. The major countries for producing world animal feed, namely China with a share of 19.6%, followed by a number of countries, namely America with 17.4%, Brazil 6.8%, then countries such as Mexico, Spain, India, Russia, Japan and Germany as well. are major producers of animal feed. the rest by countries around the world. Or with a combination of China, the United States, Europe and Brazil, accounting for more than 60% of world animal feed production with almost half of the feed production being poultry feed. It is estimated that there are more than 8,550 feed factories in China with a production of 179 million tons, 6,012 feed factories in America with a production of 173 million tons, 1,556 feed factories in Brazil with a production of 68 million tons. With an estimated human population in 2050 reaching 9.6 billion, it is estimated that the need for feed will be huge.

Meat is an important source of protein for humans. But for Muslims consuming meat does not only depend on the protein content of the meat, but the type of livestock, slaughtering, and processing it until it is ready for consumption must comply with Islamic law. The prohibited livestock animals cannot be farmed or even consumed because the law is haram (prohibited) for Muslims. Based on a country's animal feed production, it can also be seen what kind of livestock and meat they consume. For example, the Netherlands with about 75 feed factories, the production of animal feed reaches 12.2 million tons per year, the distribution of 5 million tons of pig feed, 3.7 million tons of beef and dairy cattle, 3.1 million tons of poultry and 0.4 million tons other livestock. Meanwhile, Turkey recorded animal feed production of 10.5 million tons with a composition of 4.2 million tons of feed for dairy and beef cattle, 4.6 million tons of poultry, and 1.5 million tons of other livestock. While globally the composition is as follows: poultry feed production is ranked first with a portion of 45%, followed by pig feed at 11%, three ruminants 10% and the rest, such as fish, domesticated and horse feed. Indonesia with a majority Muslim population should also prioritize developing a halal-based animal feed industry so that it is in line with Islamic law. Halal issues are an important and fundamental problem for Muslims in matters of food.

Sources of feed, especially its availability, are vital for animal feed production. A number of countries even have to import various raw materials for animal feed. Even in Europe and America leftovers are also used as a source of raw material for animal feed, which is estimated at 60% in Europe and 50% in the United States. Although world animal feed production reaches around 1 billion tonnes every year, basically the world's major feed producers who dominate production are not much. Currently, it is estimated that there are around 31 thousand feed factories worldwide, with a distribution of one thousand in Africa, 13 thousand in Asia, 5 thousand in Europe, 3 thousand in Latin America, 6 thousand in North America and 288 in the Middle East. Charoen Pokphand (CP), a company based in Thailand, is among the top 10 global feed mills with a production of around 27 million tonnes / year. Furthermore, the China-based company New Hope with a production of 20 million tons / year, then the American company Cargill ranks third with 19.2 million tons, followed by another American company, namely Purina Animal Nutrition with 12 million tons. Other large companies, BRF (Brazil) 11 million tons / year, Tyson Foods (USA) 10.3 million tons / year, COFCO (China) 8.3 million tons / year, Ja Zen-Noh (Japan) 7, 5 million tons / year, Shaungbaotai Group (China) 6.6 million tons / year, and Wen's Food group (China) 6.5 million tons / year.

The era of bioeconomy, which is getting closer and closer, is increasingly encouraging the use of renewable materials for various human activities such as energy, packaging, clothing and so on. The demand for sustainability is an obligation for various industries in this era, including the animal feed industry. A number of locations in Indonesia have created and launched energy plantations to welcome and be in line with the bioeconomy era. Energy or biomass plantations with the main focus on wood utilization, but have not yet utilized the potential of leaves as a by-product of these plantations. Gliricidia is a plant species that is widely used because it is a fast growing and short rotation coppice crop so that in addition to the fast harvest time there is also no need to replant until a certain time. Gliricidia leaves have high nutrition, no less protein content than palm oil cake, soy bean meal and so on, so they have the potential for animal feed production, especially feed pellets. A number of studies mention the use of gliricidia leaves as animal feed for ruminants or fish, but it is not suitable for the type of poultry.

The availability of safe, quality and affordable feed will encourage intensive livestock business. Currently, we still encounter a number of livestock that are fed in the form of municipal waste in landfills, which of course the resulting meat is not suitable for human consumption. The feed factory also indirectly encourages the improvement of food quality from meat and milk produced from livestock business. Tens of thousands and even hundreds of thousands of hectares of gliricidia plantations will produce abundant leaf waste that can be used as raw material for these feed pellets. Typical feed mill capacity is also proportional to the capacity of the farm or its consumers and also the availability of raw materials, for example in Turkey about 60% of feed mills with a capacity of less than 10 tons / hour, about 25% capacity 11-20 tons / hour and the rest with more capacity. of 20 tons / hour. In the end, it is hoped that with the advancement of livestock, it will be easier and more affordable to get halal meat, improve the quality of food and can be reduced and even eliminated the circulation of haram meat on the market.
