| Summary: | Sederhana Market is one of the markets in Bandung which generates 1.7 tons/day and
is dominated by organic waste in the form of vegetables and fruits. However, the
processing efforts carried out are still very minimal and only use conventional
composting which is done occasionally. In accordance with Jakstrada Bandung in the
Management of Household Waste and Household-like Waste, waste management
which includes processing is targeted to reach 70% by 2025. Waste management
includes waste processing. Organic waste can be processed through biological
processes and determination of the most suitable technology for Sederhana Market
Waste use simple additive weighting and it is found that BSF Composting is the chosen
alternative. Waste processing with BSF larvae has a waste reduction rate of up to 60%
in 2-3 weeks and produces by-products in the form of alternative animal feed and
residues that can be processed into compost. However, processing market waste with
BSF larvae requires pre-treatment because the water content of the media is too high
for larval growth. Reducing the water content is carried out by adding coconut dregs
which are high in crude fiber content. Coconut dregs was chosen because it is widely
available in the Sederhana Market and contains additional nutrients in the form of fat
and protein which are good for larval growth. This study aims to determine the effect
of adding coconut dregs on the effectiveness of reducing Sederhana Market waste and
the growth of larvae. Determination of the ratio between coconut dregs and market
waste was carried out using a completely randomized design including 5 ratio
variations, 1 control and 3 replications. The research was carried out by feeding once
every 3 days as well as final testing of waste decomposition results to be compared
with SNI compost quality standards. Statistical analysis has been done to analyze
correlation between coconut dregs added and waste reduction. The highest percentage
of waste reduction obtained was 80% and was achieved by variation A with an initial
water content of 91%. The highest larval growth rate was also found in variation A,
which reached 60% every 3 days. Of all the tests, only variation B (80% market waste
: 20% coconut dregs) met all the compost quality parameters specified by SNI.
