TURNITIN _INTEGRATED SOLID WASTE MANAGEMENT OF THE PALM OIL MILL AS AN EFFORT TO REDUCE GLOBAL WARMING AND ENVIRONMENTAL POLLUTION

The increase in the palm oil industry in Indonesia is followed by an increase in oil palm empty fruit bunches (EFB/EFB) solid waste. Various EFB waste management efforts have been carried out by utilizing it as raw material for bioethanol production, briquette making, compost making, particleboard manufacturing, Biomass power plant, pulp and paper production, and biogas production. During this time the EFB management is carried out individually and has different environmental, economic and social impacts. For that reason, in this study the author developed an integrated system of managing EFB waste that are more environmentally friendly, economical and provides a better social impact to the community by utilizing some existing processing technology.

The purpose of this study was to determine the potential for mushroom cultivation using the EFB planting media which was carried out in an integrated and environmentally friendly manner, thus providing many benefits to the community and supporting a sustainable palm oil industry. The method used in this study is an experimental method and literature study that produces observational data in the form of tables and graphs that were analyzed descriptively.

The results obtained in integrated EFB management (mushroom production, biogas, compost and liquid organic fertilizer) have high economic feasibility with an investment of 1.334.468.908 IDR, IRR of 65%, B / C ratio of 2.07 and PBP for 1.5 years. Management of every ton of EFB with an integrated business concept can produce 90 kg of mushroom mushrooms, 11.14 m3 of biogas, 73.5 kg of dry compost, and 1.0 m3 of liquid organic fertilizer. Integrated management is also environmentally friendly because it is able to reduce green house gas (GHG) emissions by 436.02 kg CO2e with energy consumption of 120.17 MJ (economic value of energy 1 MJ / ton of EFB = 35.515 IDR) and provide an economic value of EFB of 4.267.885 IDR. Integrated EFB waste management can be used as a superior program for the corporate social responsibility (CSR) of palm oil mill companies to the surrounding environment.
