Abstract

Solid waste from “agar-agar” (gelation made of seaweed) factory in huge amount and has potency to pollute the environment if it is not well managed, obviously has opportunity to be used as compost. The purpose of this research is to find out the characteristic of composting process of agar-agar factory’s waste, and the quality of its compost product,based on 2 ( two ) treatments i.e. with and without the use chicken manure starter. In general, result of the research showing that there is no significant different between using chicken manure starter and not using chiken manure starter, with understanding that both composting process can be done in aerobic condition (normal) with compost quality according to mature compost criteria. However, specifically the rate of waste decomposition (composting process) of using chicken manure starter looks faster in initial period of decomposition.Key words : compost, “agar-agar” factory waste, chiken manure starter.

Abstract

Early sorting process in composting municipal solid waste is labour intensive, so that the production cost is high. This research is carried out to know how the quality of the compost product and the characteristic of composting process if the early sorting is not done. The research result shows that without early sorting composting process has been done well, similar or not different significantly to the process with early sorting and has good quality. The positive result of this research is to increase the efficiency of the worker or reduce the production cost of manufacturing compost, because the process in making heap can increase from 1 m3 / person / day to 3 m3 / person / day. Key Words: Compost, composing,municipal solid waste, sorting

Abstract

The large scale composting activity needs mechanical equipments foroperational efficiency like The Cakung Slaughterhouse has been done.Installation of mechanical equipments and buildings make it costly compare tomanual composting activities. The cost of mechanical composting need to becounted such as investment, operation and maintenance cost in order to getthe specific cost of compost production. This can be used for pricing compostproduct. According to the analysis, the best pricing for compost product is morethan Rp. 807/kg, for example Rp. 1000/kg compost. It means that CakungSlaughterhouse need increase gradually the existing compost price from Rp.500/kg to Rp. 1000/kg compost. It need for guarantying for sustainable compostproduction.Key Words: Slaughterhouse, mechanical compost, specific cost
