Abstract
In order to meet the land requirements for housing construction of its employees, PT Semen Baturaja Tbk. (PTSB) opens approximately 27 ha of land which is estimated to have approximately 2700 less productive oil palm trees. The opening of the land will produce substantial palm biomass. One of the efforts to utilize palm oil biomass waste is by processing it into compost. Compost can be used for rehabilitation of ex-mine land by PTSB. So far, PTSB has no experience in the field of composting, therefore PTSB in collaboration with the Faculty of Forestry, Gadjah Mada University produces compost from waste palm oil biomass. The method used in this service activity is socialization, participatory composting, and mentoring in the field. The output of this activity is in the form of palm biomass compost and knowledge about the technology of the composting process for PTSB. The amount of compost that can be obtained from 8 oil palm leaf mounds is 248.9 tons while that of the oil palm stem is 1,236.6 tons. Compost fertilizer after composting for 2 months has a C/N ratio of 13.7. The cost for composting is Rp. 591,405,000, with a potential profit of Rp. 6,093,232,500, -. The impact of knowledge on composting is saving on spending on PTSB to buy fertilizer for land rehabilitation and handling the problem of biomass waste.
