Optimization Of Composting Time from Palm Fronds and Empty Buttons Of Palm Oil (Elaeis guineensis Jacq) with Various Bioactivators

Composting or decomposition is a method of processing solid waste which has high content (70% -80%). Empty fruit bunches from the Crude Palm Oil Factories and fronds palm oil (TM) plants have potential to be used as organic fertilizer. without decomposer takes long time seven months, so bio activator needed speed up process. Research with aim determining influence various activators in accelerating composting empty been carried out at PT. Bahana Karya Semesta unit Sungai Air Jernih Estate, Pauh, Sarolangun, Jambi November 2021-February 2022. The was Complete Randomized Design (RAL) two factors. first factor bioactivator consisting four types such LCPKS (liquid crude factory), MOL (Local microorganism), EM4 (Effective microorganism 4) cow dung. second one compost material bunch/EFB (5 kg), EFB + (2.5 kg 2.5 LCC (legume cover crop) (2 2kg 1kg). C/N ratio, temperature, campiness, shrinkage, crumbly, color were also recorded. results showed that could decompose some parameters we measured. analysis ratio each treatment gave different results. had highest 91, meanwhile, combination EFB+cow dung lowest 23. pH value 6.36 depreciation 57.48%. variety same on compost. Meanwhile, type effect pH,
