Abstract

The composition of waste in Indonesia is dominated by organic waste. The waste processing process must be improved to prevent pollution in the market environment. The bioconversion process using Black Soldier Fly larvae or maggots is an effective way to process organic waste. The aim of this study was to determine the effect of feeding on the initial maggot biomass to the addition of the final maggot biomass, determine the maximum maggot weight and determine substrate consumption. This quantitative research used a completely randomized design method consist of five treatments and four replications. The various feeding between total feed and larva were A treatment (270 gram: 150 gram), B (210 gram : 150 gram), C (150 gram : 150 gram), D ( 90 gram : 150 gram) and E ( 30 gram : 150 gras). The data analysis technique used variance test and Duncan’s mean difference test. The result showed that the addition of coconut pulp feed affects to the final weight of the maggot and the value of substrate consumption. The addition of coconut dregs feed which maximally affects to the final weight of the maggot showed in A treatment which ratio coconut dregs: larva (270 gram : 150 gram). The A treatment gave an average final weight of maggot 195 grams in 18 days. The maximum reduction of coconut dregs in the bioconversion process was observed in treatment E with a substrate consumption value of 55%.

Abstract

Solid waste known as garbage still becomes one of the most concerning issues   in Indonesia. It increases every year; however, the landfill was not expanded. The accumulation of garbage could give a negative impact on the environment and health. Due to this reason, there is an alternative suggested to reduce the garbage and its sources. The initiative called ‘Bank sampah’, itis a garbage treatment system which is managed by the community. In addition, the Reduce, Reuse, Recycle (3R) laystall was built to carry out some ‘Bank Sampah’. This study conducted a preliminary design of 3R laystall at Desa Karyamulya Kecamatan Cisaga Kabupaten Ciamis.  The design of the 3R laystall using black soldier fly method to decompose organic materials is employed in this research. The quantity and the density of the garbage were required to determine the design of the lay stall. Stratified random sampling was conducted for 8 days. Desa Karyamulya generates 2.361 liters/person/day or 0.236 kg/person/day. According to a population projection for the next 10 years, the estimation of garbage composition consists of food waste (52.15%); plastic (23.58%); paper (9.23%); fabric (0.45%); wood/leaf (6.38%); diapers (2.85%); metal (0.94%); rubber/leather (2.19%); glass (0.17%); and styrofoam (2.04%). From the quantity and composition of the garbage, it requires approximately  94 m2 of the area and an  estimated  funds needed as Rp. 483.908.600
