<![CDATA[The Research on formulation of coconut fiber waste and animal manure into biocomposes (decomposer: Aspergillus sp.) has been carried out in Langaleso Village, Dolo Subdistrict, Sigi Regency, Central Sulawesi, Biotechnology Laboratory of the Department of Biology and the Soil Science Laboratory, Faculty of Agriculture at the University of Tadulako Palu, in March to August 2018. The purpose of this research was to formulate the basic substrate (BS) of coconut fiber waste and animal manure supplementation into biocompost using decomposer: Aspergillus sp. The study was designed in a completely randomized design consisting of five treatments and four replications. The treatments arrangement is a comparison of the base substrate of coconut fiber (BS) with animal manure supplements as follows; P0 (BS 100%, without supplements), P1 (BS 90% + supplement 10%), P2 (BS 80% + supplement 20%), P3 (BS 70% + supplement 30%) and P4 (BS 60% + supplements 40%). Parameters of observation include; physical indicators (aroma, color and texture), biology (fungi identification) and chemistry (analysis of C-organic content and nitrogen). The results showed that the P4 treatment showed the best biocompost quality with physical indicators (compost-smelling aroma, black in color and soft texture), biological indicators (identified as Aspergillus sp and Mucor sp contaminant fungi), chemical indicators (40.5% C-organic) , N 1.36% and 29.7%).]]>
