| Summary: | Muara Gembong sub-district, Bekasi district, faces significant sanitation problems as 60% of
the population still uses open defecation, which causes faecal sludge (LT) to pollute the
Citarum River estuary directly. Toilets not connected to the piped sewerage system and faecal
sludge management that do not meet national standards cause serious problems. Using Black
Soldier Fly Larvae (BSFL) to treat faecal sludge is an innovative approach to reduce the
volume of faecal sludge and produce a high-protein product as animal feed. However, the
direct use of faecal sludge as BSFL substrate results in suboptimal larval growth. This is
because faecal sludge lacks the nutrients needed for larval growth. In the present study,
technology using BSFL-based has been proposed and tested for treatment of faecal sludge in
that area with the addition of co-treatment from fishery waste (IKN) and pidada fruit waste
(PDD) to improve the nutrition. In addition, the products of this process are used as animal
feed and compost raw materials. Seven feeding substrates were then formulated.
Approximately 100 mg substrate/larva/day was given to the 10-day-old BSF larvae for the 12-
day treatment process. The performance process was monitored in terms of survival rate (SR),
waste reduction rate (WR), and bioconversion rate (BCR). The study results show that the
substrate with a composition of 50% sludge and 50% fishery waste (variants F1-S2) gave the
best results, with SR of 92.75%, WR of 41.78%, and BCR of 12.06%. On the other hand, the
addition of pidada fruit decreased SR and WR, with the variants of 50% fecal sludge and 50%
pidada fruit waste (F1-S1) giving SR of 63.17% and WR of 41.78%. The product of this process,
BSFL for animal feed needs further processing because they contain patogenic bacteria
(Salmonella and E. coli) and the residue for compost is still relatively immature based on the
C/N ratio. |
