Abstract

Black Soldier Fly Larvae (BSFL) is known as an effective insect for food waste treatment which could help in accelerating the composting process. This relates to the aim of this research which is to determine performance on food waste composting using BSFL in the case study area. Therefore, this research is conducted by identifying food waste generation in Taman Pura Kencana, Johor. At the same time, to compare lifecycle of BSF in case study with previous study and to identify decomposing process of food waste samples based on physical properties. Lastly, to identify decomposing rate and evaluate performance on decomposing rate of food waste samples using BSFL. Sample of respondents for food waste generation in Taman Pura Kencana consists of 38 households and 10 restaurants using Raosoft Sample Size Calculator. Food waste generation data were collected for 3 months from April to June 2021. Lifecycle of BSF in case study was monitored at the Solid Waste Research Centre (SWRC) by recording time interval between each phase of lifecycle compared to previous study. Decomposing process of food waste samples using BSFL was measured through physical properties namely moisture content, temperature and pH. In the meantime, decomposing rate of food waste using BSFL was analysed through decomposing days and calculations using same quantity of BSFL but different amount of food waste samples. Total food waste generation from respondents in Taman Pura Kencana was 1057.03 kg. Lifecycle of BSF in SWRC took 38 days to 57 days per cycle compared to previous study which took about 42 days per cycle. The most suitable food waste sample using 12 g of BSFL was sample T5 regarding to the highest value of DMCR. Based on decomposing rate of food waste samples using BSFL, average waste reduction index (WRI) by decomposing food waste samples using BSFL was from 7.90 (%/day) to 9.30 (%/day) which was the highest compared to composting by other insects (4.0%/day to 7.0%/day)
