Problems of Wood Harvesting from Calliandra Energy Plantation and High Potassium Content in Wood Pellet Ash: Two Things That Need Attention

The factor of production efficiency and standard and stable product quality is the mindset of the industry, including for the wood pellet industry from the calliandra energy plantation. Manual wood harvesting operations make production efficiency low. The high daily need for wood pellet raw materials from energy plantations requires mechanization equipments for harvesting the calliandra plantation. Meanwhile, calliandra wood pellet products with high ash content containing potassium also require certain treatments so that the wood pellet products meet the standards for power plants in general. The stability of production quality and quantity is closely related to the quality of the production equipment used. These two things must be an important concern for wood pellet producers from calliandra energy plantations with large capacity and export orientation.

The wood pellet industry from the calliandra energy plantation is new, so there are not many references. The history or the origin of this industry comes from the project of the Ministry of Forestry of the Republic of Indonesia at that time which created an incubator-scale industry as a pilot for the production of wood pellets from the calliandra energy plantation located around Geger Hill, Bangkalan, Madura, East Java about 12 years ago. At that time, there were actually several wood pellet industries operating, but all of these wood pellet factories or industries used raw materials from wood industry waste, such as sawmill industry waste, barecore industry waste, plywood industry waste and so on.

Calliandra trees are also not new plants to the public. This tree has been widely planted but previously with different purposes, namely for reforestation, for animal feed or for honey bee farming. While for bioenergy purposes or wood pellet production, planting calliandra trees in the form of energy plantations is something new. That is why in the early stages, calliandra wood harvesting was still done manually and this was ineffective and inefficient on large-capacity plantations. In addition, the wood pellet product has not been analyzed or examined completely / comprehensively so that the high potassium content (ash chemistry) in the ash has not been detected. When the requirements for the maximum content of potassium / potassium must be met, special treatment needs to be done.

In addition, an important thing to note is the target types of products produced. If the calliandra plantation not only produces wood as raw material for wood pellet products, but also processes leaves for animal feed, then the harvesting mechanism is very influential. The leaves from the calliandra plantation must also be harvested effectively and efficiently or the same as the wood products. This could be, for example, the trees and leaves are harvested together and then taken to a place and separated to be processed individually. Or it could be that the wood and leaf products have been separated at the time of harvesting, then each goes to its respective processing unit. The equipment used must also be different according to the choice of the harvesting mechanism. Meanwhile, honey products from bee farms that utilize calliandra nectar are not affected by this mechanism, this is a separate honey production process and is related to the flowering season of the calliandra tree itself.

Along with the global decarbonization trend, the prospects for calliandra plantations are increasingly bright. It is predicted that many calliandra plantations will be created, which are intended primarily for bioenergy production such as wood pellet production, and this is in line with the carbon neutral scenario that supports the net zero emission program. The use of wood pellets is mainly for fuel in coal-fired power plants through the cofiring mechanism. In the next stage, it is possible to use 100% of the power plant fuel using wood pellets (fulfiring). The high potassium content is generally a problem in applications for this power plant, although there are types of power plants that technically do not have a problem with the potassium content, but the production of wood pellets from calliandra with low potassium content is certainly preferred.

Optimizing Calliandra Energy Plantations for Energy, Food and Feed, Is It Possible?

Calliandra energy plantations as the name implies are indeed prioritized or for the main purpose of producing energy from biomass, either wood pellets or just wood chips. This is because wood is the main product of the energy plantation, while leaves and flower nectar are by-products or are considered waste from the wood pellet or wood chip business. However, if the use of leaves for animal feed and flower nectar for honey production has an economic value that approaches or even exceeds the wood pellet product, then it will be a different story. Calliandra leaves, like indigofera leaves and glicidia / gamal leaves, have a high protein content, while this protein element is the most expensive source of nutrition of all the elements in animal feed products, while calliandra honey is one of the best quality honeys compared to other honey products such as acacia honey, kapok honey, rubber honey and so on.

Synchronization between honey and wood production is very important in the energy plantation to maximize profit. In honey production, the first time the calliandra flowers and the next flower cycle are very important. Don't let it be that just because of ignorance of the flower cycle, many benefits that should have been obtained are lost. In addition, for sustainable and optimal honey production, not only calliandra nectar is needed, but also a number of certain plants as support, both for additional bee feed and for making beehives. When all that is available is calliandra nectar, honey production will be maximized but will not be sustainable because the bee colony will shrink and then disappear. This is the importance of plantation engineering with a number of species or types of certain plants if honey production is also an important product in the calliandra plantation-based business.

Calliandra leaves in abundance will automatically be obtained when the calliandra trees are cut down or harvested. The calliandra leaves need to be separated from the wood and twigs to be used for animal feed. Animal feed products from calliandra leaves can be in the form of fresh leaves or processed leaves in the form of pellets, or hay. This makes it possible to have a leaf pellet factory in addition to the wood pellet factory. With an estimated leaf volume of 1/4 of the wood but the price of leaf pellets is around 3 times the price of wood pellets. So the profit from utilizing leaves into pellets (leaf pellets) is very large, estimated at 1/2 to 3/4 of the wood pellet turnover. This is certainly a serious consideration and cannot be ignored.

A comprehensive understanding of calliandra plantations for energy, food and feed is indeed very important to maximize profits from calliandra plantation-based businesses. This will encourage the calliandra energy plantation to grow further. In addition, the legality aspect and land selection for the location of the calliandra plantation. This is because, especially for wood pellet products in general, it is for export orientation and especially for Japan and Europe, environmental or sustainability certification is very important and even required so that the legality aspect (which is clear and clean) and land selectivity according to its designation including the history of the land are also very important. So optimizing calliandra energy plantations for energy, food and feed is possible if the terms and conditions are met.

Unlike Honeybees, Why Does the Development of Energy Plantations Get Little Attention from the Goat/Sheep and Cattle Livestock Industry?

Along with the global decarbonization trend, energy plantations are increasingly developing in Indonesia. The creation of these energy plantations has the main purpose of producing biomass fuels such as wood chips and wood pellets. Wood chip production because it is easier and the production equipment is easier and cheaper is usually done before wood pellet production and for more details can be read here. In addition to the use of wood as the main product of energy plantations, by-products that can be produced from energy plantations are animal feed from the use of leaves and honey from honey bee farms. And with the utilization of all parts of the tree (whole tree utilization), the energy plantation-based business is not only more profitable, but can also remain sustainable.

The honey production that can be produced from the development of energy plantations will also be very large, namely tons or even hundreds to thousands of tons in proportion to the area of ​​the energy plantation. Moreover, the plants cultivated are red calliandra whose nectar will produce one of the best quality honey. Regarding the development of the energy plantation, even API (Indonesian Beekeeping Association) responded optimistically to the development of the energy plantation, because in the next 5 years it is targeted that honey production will increase by 300% so that the import of tens of thousands of tons of honey from China can be reduced and even be sufficient, more details read here. In addition to honey, several derivative products will also be produced from honey bee farming, namely royal jelly, bee pollen, bee wax and bee venom which also have many benefits. The motto "Gertakanlah" namely the Bee Feed Planting Movement is very much in line with the development of this energy plantation.

But this condition is different from the world of animal husbandry, especially ruminant livestock, namely goats/sheep and cattle. In fact, Indonesia's meat needs are also very large, most of which are still met by imports. Unlike beekeeping which is responsive to the development of the global decarbonization trend, namely more specifically with the energy plantation, the world or livestock industry players have not responded to this, even though the production of feed from this energy plantation will also be very large. Even the main element of animal feed from red calliandra leaves is protein and protein is the most expensive element of animal feed nutrition. In addition, with this livestock, it is also possible for integration to occur as in the diagram above. Integration will provide optimal benefits and production becomes efficient, thus providing even greater benefits.

Calliandra Honey from Caliandra Energy Plantation

Calliandra honey can be said to be one of the best honeys in the world. The quality and taste of calliandra honey are above other honeys such as rubber honey, acacia honey and cottonwood honey. But it turns out that the production of calliandra honey is not as easy as other honeys. A number of things need to be done so that the target of getting the quality and quantity of calliandra honey can be achieved, including engineering or enrichment of energy plantation plants and selection of appropriate honey bee species. This is why before planting calliandra in the energy plantation, it is necessary to discuss it first with a honey bee farming expert, if indeed the energy plantation will also produce honey as a side product or additional product, in addition to the main product in the form of wood pellets from its wood. Making engineering or enrichment of energy plantation plants is much easier before planting activities are carried out than after the energy plantation has been completed or is producing.

Factors that meet the sustainability of a farm or bee colony are important things that must be met by beekeepers or honey producers. These factors include the availability of nectar, pollen, resin and water (abbreviated: neporea). The balance of these factors needs to be created to maintain sustainability and also optimize honey production from the honey bee farm. Of course, the specific needs of each factor are also closely related to the type of bee species being farmed. For example, for the availability of abundant pollen but minimal nectar sources, honey production will also be minimal, or vice versa, abundant nectar sources but minimal pollen sources, then honey production is abundant but the bee colony will shrink or decrease or even become extinct, meaning there is no sustainability. Certain bee species such as the trigona family even require more resin sources than other honey bee species. Pollen is a source of protein for bees so it is vital for the life of the bee colony. Calliandra is a source of nectar, so it is not sufficient to rely on food sources from only one plant species.

By maximizing the potential of the plantation, meaning not only processing the wood, maximum profit will be obtained. With such high quality calliandra honey, it would be a shame if it was not utilized. Calliandra honey production will even provide significant additional profit because it is estimated to produce 1 ton of honey per year from 1 hectare of calliandra plantation. And currently Perhutani (Indonesian state-owned forestry company) has a wider honey production area. Based on API (Indonesian Beekeeping Association) data, Indonesian honey needs reach 15,000 tons-150,000 tons per year. Of that amount, 50% of the needs are supplied from China. With the increasing development of calliandra energy plantations, especially for wood pellet production, which are managed by the government and private sector, it is hoped that it will also increase Indonesian honey production.

The main problem of beekeeping is the availability of food for bees or flower nectar. Calliandra, which is a fast-growing plant and is cultivated massively, will significantly boost honey production, even targeted to increase threefold (300%) in the next 5 years. Moreover, with nine of the world's eleven honey bee species living in Indonesia, this country should be able to meet its own needs. This is so that honey imports can be reduced and Indonesia will be able to export honey. In addition to honey, bee farming will also produce several derivative products, namely royal jelly, bee pollen, bee wax and bee venom.

Leaf Pellets from Energy Plantations

Calliandra leaf pellets
With an estimated leaf volume of 1/4 of the wood but the price of leaf pellets is around 3 times the price of wood pellets. So the profit from utilizing leaves into pellets (leaf pellets) is very big, estimated at 1/2 to 3/4 of the turnover of wood pellets. Whereas calliandra leaves are usually only considered by-products or waste in energy plantations.

And almost the same as gliricidia leaf pellets, if these plants are planted in the energy plantation.

As a reference for indigofera zollingeriana leaf pellets:

Both calliandra, gliricidia and indigofera are groups of legume plants whose leaves are suitable for animal feed rich in protein. Protein is the most expensive nutrient element in animal feed.

Energy Plantations: Why Calliandra (Calliandra Calothyrsus) or Gliricidia (Gliricidia Sepium)?

Since 1937, calliandra has been planted in Perhutani and wider areas along with reforestation programs and supporting firewood and animal feed. And also since 1974, Perhutani has distributed calliandra seedlings to forest farmers and used them as boundary plants between forest areas and rural areas or agricultural land. Calliandra cultivation at that time was mainly aimed at providing firewood and animal feed for people living in the forest, and reducing dependence on kerosene for cooking. Calliandra is used as a terrace plant (erosion control) with high slopes to strengthen the main plantation, for example with teak plantations, and also for soil protection purposes, because it can increase soil fertility through the ability of its roots to absorb nitrogen in the form of root nodules.

While the type of gliricidia plant is widely used as an edge plant or hedge plant to prevent large livestock from entering the forest. The wood is used as firewood and the leaves are used as animal feed. The wood can be harvested quickly, and pruning is also done with a fast process. So it can be said that, it is not recommended to plant new species that have unknown characteristics until there is adequate research activity on the species.

For example, acacia species are relatively fast-growing species but it is not widely known whether they can be used and managed with a sustainable coppice system. And also these types are not like calliandra and gliricidia plants, although easy to cultivate and harvest, but have not proven to be suitable for the application of short rotation coppice systems, and are also rarely planted on a larger scale.

Although calliandra and gliricidia are not native tree species in Indonesia, they have long been introduced, and can be found almost throughout the island of Java. Calliandra and Gliricidia are very popular in agricultural areas in most parts of Java. In addition, there have not been many reports describing the presence of pests and / or diseases associated with either species. Wood produced from calliandra and gliricidia plants has relatively good physical and chemical characteristics to be used as firewood or as raw material for wood pellets. Its calorific value is high and its ash content is low.

Indonesia as a tropical country even with the largest land area in Southeast Asia will have great potential to develop the energy plantation. Energy plantations are essentially energy sources or likened to batteries, which store solar energy in plants, the energy plantation, for more details can be read here. Although the development of various types of renewable energy continues to be accelerated, to store energy in large capacities will require a very large battery. The battery research is also estimated to take a long time and high costs, so that in the context of decarbonization, biomass energy can be used for cofiring and even fulfiring until the time the large battery can be applied.

Energy Plantations: Not Only Wood Pellet Production But Must Also Support the Livestock Industry

The concept of energy plantation or biomass plantation by utilizing the whole tree seems to be still unpopular at this time. But sooner or later, God willing, it will happen because profit-oriented wood pellet companies will certainly maximize this aspect or profit, of course as long as it does not damage the environment and CSR (Corporate Social Responsibility) will be pursued in other ways. The main orientation currently focusing on wood products for wood pellet raw materials is certainly a good thing, but it would be much better if the benefits of all parts of the tree could be maximized. If this can be done, the benefits will not only be in the energy sector but also in food and feed, important sectors that are essential in human life.

The main composition of energy plantation leaves such as calliandra and gliricidia is protein and this protein element is an important and most expensive component compared to other elements of animal feed. With a large volume of leaves from energy plantations, it should support the livestock industry and not just be thrown away because it is just a by-product or waste that is less useful. In fact, from the livestock industry side, the opposite is true. The utilization of these leaves can be used directly on livestock or processed into animal feed in a processing industry depending on the local situation and conditions.

Large farms can be made from the utilization of energy plantation leaves as well as animal feed factories from the leaves. Leaf pellet production can be done with a production process similar to wood pellet production so that a wood pellet factory adjacent to a leaf pellet factory is also very possible. Like export-oriented wood pellet products, leaf pellets can also be the same. Meanwhile, if a large farm is to be carried out, waste from the livestock farm or animal waste can be used as raw materials / substrates for biogas production. The biogas can then be used for drying in the production of wood pellets or leaf pellets or used for electricity production. The residue from the biogas will become organic fertilizer, either solid organic fertilizer or liquid organic fertilizer. A simple diagram as below.

Thousands of cattle or breeding cattle are imported into Indonesia from Australia and New Zealand and cattle fattening is a promising business in Indonesia because the need for beef has not been met until now. The shortage of beef is met by importing buffalo meat from India and beef from Brazil. Support for the availability of abundant and quality feed is one of the important aspects of self-sufficiency in this meat. In addition to cattle, the need for goats and sheep is also very large. Yogyakarta, a city that is also famous for its goat satay cuisine, needs more than 1500 heads of sheep per day. In addition, the need for aqiqah and Eid al-Adha is also very large. The sheep export market is also very promising, which until now has not been met due to various factors, one of which is the feed factor. Feed in the livestock business plays a very important role or even around 70% of the cost of livestock is the cost of the feed. And livestock is a link in the chain of food needs for humans so that it is inseparable.

Large Capacity Wood Pellet Production Cannot Be Done on Java Island?

Raw materials are a vital aspect of a production activity. No raw materials means no production. Likewise in the wood pellet industry. The availability of raw materials is absolutely necessary for the continuity of the wood pellet business. To maintain the supply of raw materials, wood pellet factories must have reliable sources of raw materials. Currently, most or even all wood pellet factories on the island of Java rely on sources of raw materials for wood pellet production from wood waste, especially sawdust from sawmills and wood processing industries. 

Currently, coal-fired power plants in Java are running a coal cofiring program with biomass to reduce carbon dioxide emissions or decarbonization. The use of coal in these power plants will be reduced while the use of renewable energy, especially biomass, is increased. The biomass currently used for cofiring is sawdust with a volume of up to hundreds of thousands of tons per year. A very large amount. Wood pellet factories that use sawdust as raw material must compete with the cofiring program in these power plants. This competition increases the price of sawdust because the supply remains the same but demand increases. Disruptions in the supply of raw materials in these wood pellet factories result in disruptions in production and automatically their business aspects.

With these conditions, large-capacity wood pellet production in Java Island becomes less attractive. In fact, the portion of biomass use, especially sawdust, will continue to increase along with the decarbonization program to achieve net zero emissions by 2060. This is increasingly burdensome for wood pellet factories that rely on raw materials from buying sawdust. Wood pellet factories in Java can run well if the availability of raw materials can be maintained and this can only be realized in two ways, namely first using their own raw materials, this can be done by sawmills and wood processing industries that utilize their own waste for wood pellet production, and secondly with raw material sources from energy plantations. Energy plantations that are specifically dedicated to wood pellet production will be able to maintain the stability of the supply of raw materials for wood pellet factories. Wood pellet factories can partner with Perhutani for the second point above.

Why Has Large Capacity Wood Pellet Production from the Calliandra Energy Plantation Not Been Realized?

 

As a tropical country that has the largest land area in Southeast Asia, the potential for fuel or renewable energy from biomass, especially wood pellets, is very potential and promising. To maintain the stability of large capacity production volumes and their continuity, wood pellet production must use raw materials from energy plantations or biomass plantations. Energy plantations from short rotation coppice & fast growing species from legume groups such as red calliandra (Calliandra calothyrsus) have been a concern for quite a long time, but why has this large capacity wood pellet production not yet been realized or has no industry realized it? Below could be two main factors causing this:

1. Quality of calliandra wood pellets

The characteristics of rotational crops and fast growth of the legume group are that they contain quite high levels of potassium and sodium (K+Na) in their wood. Potassium has the property of having a low melting point so it will be problematic for heat exchangers in power plant boilers in general. The high potassium content makes its use unsuitable for power plants in general, namely those that use pulverized combustion (PC). Red calliandra (Calliandra calothyrsus)  in particular is the same, so with a large production capacity, the quality of export-oriented wood pellet products needs to be improved by reducing the content, especially potassium and sodium (K+Na). 

The process of reducing K + Na, which is part of the ash content, is carried out using a leaching / washing process. This unit needs to be added to the wood pellet production process from red calliandra. Apart from making calliandra wood, the raw material for wood pellets, this process becomes wetter, it also produces waste water. This will increase the production costs of red calliandra wood pellets.

Although it is possible that the leaching/washing process was not carried out so that the resulting wood pellets still have a fairly high K + Na content, they still have the potential to be used for certain types of power plants, such as those with fluidized bed and stoker technology. However, this type of power generation technology is not as common as the use of pulverized combustion (PC) technology. So that market acceptance for the production of calliandra wood pellets is large or can be used in all types of power plants, the leaching/washing process should be carried out.

2. Utilization of only certain parts (partial) of the plant, and not comprehensive (whole tree utilization)

When it only use wood for wood pellet production, it means that only part of the plant is used (partial) or there are other parts of the plant that are not used, namely the leaves and flowers. In fact, these two parts of the plant will be able to maximize income or profits which will provide the impetus to accelerate the realization of large capacity wood pellet production from the energy plantation. The additional costs incurred for the leaching/washing process will be compensated by the income/profits from leaf processing and flower utilization.

Calliandra leaves which have a high protein content are processed into animal feed, especially into flour or also pelleted into feed pellets. Meanwhile, the nectar from flowers is used as food for honey bees in beekeeping to produce calliandra honey. By maximizing the potential of all parts of the plant (whole tree utilization) of calliandra, various products (multiple products) are produced so that the driving force to accelerate the realization of large capacity wood pellet production from energy plantations becomes stronger.

One form of gratitude for Allah SWT's blessing in the form of a country with a tropical climate with vast land is to use it in an environmentally sound and sustainable manner. Tropical areas like Indonesia are a "paradise" for biomass production, especially for biomass energy (bioenergy) in the form of wood pellets. Optimizing this potential, especially with large capacity production of wood pellets and additional products, could be a boon and a blessing for prosperity as well as a solution to global climate problems (carbon neutral fuel). And basically business judgment is also needed from the entrepreneur's side so that the entrepreneur has the courage to decide to execute this business opportunity.

Another Form of Reclamation - Energy Plantation for Wood Pellet Production and Integrated Farming

 

Post-mining reclamation is the obligation of mining companies / IUP (Mining Business License) holders so they must prepare funds for this. Apart from reforesting mining areas in forest areas, other forms of reclamation are more flexible because there are many types, but the aim can provide economic, social and environmental benefits. If the mining company does not carry out reclamation, it will receive heavy sanctions, namely a fine of up to 100 billion rupiah. Post-reclamation business or activity management is also flexible according to the agreement as long as it does not conflict with the above objectives.

Pioneering the Export of Hay from Energy Plantation Leaf Waste

The high demand for feed, especially protein elements in Europe, on the other hand, is an opportunity in itself. Leaf waste from energy plantations in abundant quantities can be used as an export commodity to fill this opportunity. These leaves can be processed into hay and then compacted (biomass densification) into large boxes (cubes) and ready for export. Under tropical climate conditions, biomass production, especially for renewable energy, feed and food through energy plantations, is an ideal solution. Wood product will be used as bioenergy, especially into wood pellet product, leaf as an export commodity for animal feed, and honey as a highly nutritious multi-functional food. Millions of hectares of potential land for the creation of energy plantations so as to maximize the benefits of land use, especially with the tropical climate conditions that support.

Learn from the state of Oregon in the United States which is successful as an exporter of hay grass as a source of fiber in animal feed. It is recorded that more than 900,000 tons per year export hay grass from Oregon to the destination countries, namely Japan, Taiwan and Korea. The business has been around for more than 30 years. The mechanization of agriculture and the use of modern agricultural techniques have helped the business grow. A number of grass species that they cultivate include annual ryegrass (Lolium multiflorum), perennial ryegrass (L.perenne), bent grass (Agrostis spp.), fine fescue (Festuca spp), Kentucky blue grass (Poa pratensis), Orchard grass (Dactylis glomerata) and tall fescue (F.arundinacea).

The difference between hay and dry straw (straw) is sometimes still confusing. Hay is made from fresh stalks, leaves and shoots of plants. Many plants can be used as hay, for example in Iowa, USA alfalfa and clover are most commonly used. If it is cut and packaged (compacted) almost all of the nutritional content is not lost and is used as animal feed. Meanwhile, straw is also made from the stalks and leaves of plants, but is cut after the plants are mature with their shoots or the fruit has been harvested for something else. This straw has very little nutritional value and is used primarily as animal bedding. The conditions for plants to make hay are fine textured, harvested at the start of the flowering season and harvested from fertile areas.

Hay production is carried out by cutting the forage (grass or leaves) then withering and drying the forage, then to facilitate storage, transportation and use, the hay needs to be compacted. Animal feed in dry form such as hay will make it able to hold out until the nutrients are maintained. The history of hay production is thought to date back to the late 19th century, when alfalfa was introduced to Iowa and became the most popular crop for hay production. Alfalfa itself comes from Central Asia which was first used for animal feed and then this alfalfa spread to various parts of the world. Legume leaves from energy plantations are also very potential as animal feed and processing them into hay will increase their utilization including their economic value. In the commercial hay industry modern mechanical devices are used primarily for compaction by making blocks or boxes with a high production target, as shown in the video in the following link here.   

Production of Synthetic Boards*, Ruminant Livestock and Animal Feed Industry from Biomass Plantation

Synthetic boards such as laminate, particleboard, fiberboard and cement board can be made from wood produced by biomass plantation. In addition to the small size of the wood, it is also of low quality which currently does not have an adequate utilization value. Forests or biomass plantations can be used as the raw material for the synthetic board. With fast rotation crops with short rotation coppice and fast growing species, such as calliandra and gliricidia, it is very potential as raw material for the synthetic boards. The production of this synthetic boards also uses the same type of raw material as wood pellets, namely wood waste or wood worth as wood waste. Wood produced from this biomass plantation is included in the second group, namely wood worth as wood waste. Even on the other hand, the large wood processing industry that produces a lot of wood waste, not a few who process the waste for the production for wood pellets and synthetic boards.

However, it would be better if the source of raw material for the synthetic boards production comes from forests or biomass plantations so that not only wood is the raw material for the artificial boards but also leaves and flowers. The leaves can then be used as ruminant animal feed and even the production of animal feed as a separate industry. While the flowers from the plantation can be used for honey bee farming. In livestock business, especially ruminants, feed is the highest cost component which is estimated to reach more than 80%. The forest or biomass plantations cover an area of thousands of hectares and are capable of being the main feed source for large ruminant livestock. Even if there is a large surplus, the animal feed industry also needs to be made independent.

Animal feed in the form of hay and pellets is suitable for long distance use because transportation costs will be cheap. Basically all parts of the tree can be utilized so as to provide optimal benefits. To maintain the sustainability of the forest or biomass plantation, good management is also needed so that the productivity performance of the forest or biomass plantation can be maintained. Along with the increasing population, the need for housing and other means of living also increases as well as food. Forests or biomass plantations can help overcome both problems.

*Synthetic boards are laminated board, particle board, fiberboard and cement board. While plywood is not included in it, although plywood is also a type of synthetic board. Plywood production from veneer sheets derived from large diameter wood, is not like this biomass plantation.

Sheep and Goat Farming Based on Energy Plantation

The need for food, especially animal protein, continues to increase along with population growth. Meat, especially from sheep and goats, is a source of animal protein that is a favorite of many people. It is estimated that the world's population will reach 10 billion in 2050 and especially Indonesia's population of 319 million in 2045. Greater Jakarta or Jabodetabek is the most densely populated area in Indonesia so that the need for food, especially animal protein, lamb and goat meat is getting bigger. Currently these areas bring in the needs of lamb and goat meat from Central Java, East Java and Lampung alternately depending on the availability of supplies for each area. This is because no single region is able to meet the needs of Jabodetabek alone. Or if these areas can always supply the needs of Jabodetabek on a regular basis then the business can continue to be sustainable and stable but of course it can overcome the obstacles in the sheep and goat business.

It turns out that a number of problems surround the sheep and goat business including the availability of seeds, breeding skills, availability of feed, marketing chain and so on. Simple things such as the availability of seeds. Although breeders in general have not used superior seeds, the availability of seeds is also a problem because many productive females are slaughtered. This is mainly due to the business competition factor, because the price of males is more expensive which makes female goats slaughtered even though this disrupts the sustainability of the livestock business. Aspaqin (Indonesian Aqiqah Entrepreneurs Association) noted that 63% of the female members 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 restaurants for eating lamb dishes, such as satay that still slaughter productive female goats.

Of course it would also be better if the sheep and goat that became the seed was the preferred or superior sheep and goat so that the quantity and quality of meat was better. The feed-to-meat conversion factor in superior sheep and goat is also higher, making it more profitable. And this is mainly the responsibility of research institutions. Dorper sheep and Bohr goats are the superior types of sheep and goat. However, there is an easier way to maintain the sustainability of the sheep farm, namely by reducing or even prohibiting the slaughter of productive female sheep and goat. In this way, the continuity of sheep and goat seeds can be maintained and even more developed. To be able to realize this, of course, requires efforts from all parties. Providing incentives or sanctions can be done to support this.

The problem of skill of the breeder is also another obstacle. Most of the sheep and goat breeders are small farmers with traditional farming techniques. This makes it difficult when used to meet routine requests, especially large quantities. Modern farming patterns must be carried out to become a reliable livestock industry as the foundation of the livelihood of these farmers. Only with this effective pattern and efficient farming can be implemented. With good preparation supported by these skills, sheep and goats livestock industry players are able to carry out sheep and goat  farming intensively so that they are expected to be able to supply the meat needs.

Sheep and goats farming is not only an effort to fulfill food sources, especially animal protein in the form of meat and milk, it is also a part of perfecting Islamic law. The population that continues to increase means that Muslim babies born to their parents are ordered to perform aqiqah. In addition, the celebration of Eid al-Adha which is held every year also requires sheep and goats as a sacrificial animal. Sheep even as sacrificial animals have many advantages over other livestock even though they are both halal such as goats, camels and cows. In the verse (Qur’an 6:143-144), the eight pairs of animals (4 pairs) are two (pairs) of sheep, a pair of goats, a pair of camels and a pair of cows. Rules in the Qur'an, something that is mentioned first has precedence over what follows. Another indication of the virtue of sheep can also be found in the event of Qurban, namely when Prophet Ibrahim was ordered by Allah SWT to slaughter his son, Ismail, then by Allah SWT saved Ishmael and replaced him with a large sheep. Then we commemorate this event every year and become the law of Qurban on Eid al-Adha every 10 Dzulhijah.

The development of energy plantations, which is increasingly being echoed lately, with the main product in the form of wood for the production of biomass fuel, both wood chips and wood pellets, will also produce waste or by-product in the form of leaves. The leaves of calliandra or gliricidia are rich in protein content so they are very good as a source of animal feed for the sheep and goats. The number of leaves produced will also be very large so that the potential for sheep and goat farms to be developed will also be very large. Even to meet the needs of sheep and goat seeds, any import is allowed under current regulations. This can also be very similar to a large capacity beef cattle feedlot, where cow seed are imported from Australia, read here for more details. The focus of sheep and goat fattening can also be very effective and efficient or has advantages such as in beef cattle if it is carried out in Indonesia. Leaf waste from energy plantations can be a potential feed.

In addition to domestic consumption, sheep and goat can also be used as an export commodity. For domestic purposes such as qurban and aqiqah, generally small sheep and goats are used, which weighs around 25-35 kg. As for the export market, sheep and goats needs usually require a weight of 35 kg and above. The export market can be a separate segment and is also basically the choice of the farmer himself. Sheep and goat farmers from Indonesia have also exported sheep and goats to a number of countries including Malaysia, United Arab Emirates and Timor Leste as shown in the table above.
