Biomass Cofiring, Energy Plantation and Ruminant Animal Husbandry

Biomass cofiring with coal in coal power plants in Indonesia as a PLN (Indonesia electricity state owned company) program to support the use of renewable energy, especially biomass, could be the closest momentum for energy plantations. The program is also an effort to achieve the target of using renewable energy of 23% by 2025, while until now it is still less than 5%. In 2020 the cofiring program has been initiated with a target of 37 coal power plants but in practice 20 coal power plants have been implemented. While in total there are 114 coal power plant units owned by PLN that have the potential for cofiring, spread across 52 locations with a total capacity of 18,154 megawatts (MW) as a target of completion in 2024. The details consist of 13 coal power plant locations in Sumatra, 16 coal poer plant locations in Java, 10 locations in Kalimantan, 4 locations in Bali, NTB and NTT, 6 locations in Sulawesi, and 3 locations in Maluku and Papua. Meanwhile, the cofiring ratio ranges from 1-5% biomass with an estimated biomass requirement of 9-12 million tons per year.

And recently there has also been an agreement between PLN and Perhutani (Indonesia forestry state owned company) and PTPN III (Indonesia agriculture state owned company) to supply biomass for the cofiring program, for further information, please read here. In this case, PLN is the owner of the coal power plants, while Perhutani owns the resources of industrial plantation forest areas both in Java (Perhutani) and outside Java (Inhutani) which can be developed as energy plantations or energy forests. Likewise with PTPN III with its land which can also be used for this energy plantation. Gliricidia sepium and red calliandra (calliandra calotyrsus) are two species of fast-rotating crops that are most likely to be used for these energy plantations. If every 4,000 hectares produces a production of 10,000 tons / month of wood pellets or 120,000 tons / year, at least 400,000 hectares are needed to meet the 1-5% cofiring target which is equivalent to 9-12 million tons per year. The potential of gliricidia leaves or calliandra will also be very abundant. And it should also encourage the growth and development of the ruminant industrial sector. Moreover, if in the future PLN increases its cofiring portion, for example 6-10% or even 20%, of course the energy plantation needed will be very large, as well as the abundant potential of gliricidia leaves or calliandra.

The Covid-19 pandemic is still ongoing with the increase in cases getting bigger in Indonesia and there is no sloping curve yet, even positive cases have penetrated more than 1 million people. It is predicted that this pandemic will become a long-term problem with indications, among others, that new variants are found so that the vaccine that has been prepared is not or less effective and the emergence of a second wave of covid outbreaks even after vaccination has forced cities and even the state to lock down. . How almighty is Allah SWT with all His will, which should further strengthen our iman and taqwa. The prolonged condition of the Covid-19 pandemic makes people afraid and avoids crowds or gatherings including professional activities such as offices and industry. This condition will also encourage the growth of efficient business activities by using various existing technologies.

Technology-based and efficient industrial developments should be the focus of the government to survive and even maintain sustainability in order to maintain the supply of goods needed by the community. Population concentrations in an area must also be reduced and properly distributed. Big cities are becoming less and less attractive. Efficient production units must be increased in number as well as their distribution should be more even. Outskirts, villages and even mountains are increasingly being enjoyed. The closer to nature or natural resource-based businesses, the more they enjoy it along with the distribution of business locations that is more evenly distributed or not accumulated in big cities. More and more world citizens also want a fairer system in regulating their lives.

Ruminants (sheep, goats and cows) farms are a potential business especially supported by the utilization of leaves waste from these energy plantations. The locations for these energy plantations are generally in forest areas which are quite far from urban areas. The leaves of gliricidia or calliandra can be processed into various forms (concentrate, hay, pellets, briquette, etc.) according to request or use. With the use of good technology, the leaves waste can be used optimally so as to support the progress of ruminant farming. The farm will also be very good if it is made near energy plantations as a source of food. To get a complete feed composition, community empowerment can be done.
