Efisiensi Penggunaan Larva Black Soldier Fly (Bsf) Untuk Mereduksi Limbah Ampas Kelapa Dengan Variasi Waktu Fermentasi
ABSTRACT
Riau Province has 419,381 hectares of coconut plantations and a production of
387.9 thousand tons. The large coconut production can produce waste. One of
them is coconut dregs, 1 ton of whole coconut processed into coconut milk
produces 250-300 kg of coconut dregs waste. Coconut dregs contain high levels
of crude fiber 33-37%. One way to manage organic waste is to use Black Soldier
Fly (BSF) larvae. BSF larvae can reduce waste by up to 55% and decompose
waste for 12-13 days. However, BSF larvae do not have enzymes that degrade
crude fiber (liginin). Therefore, fermentation using EM-4 is needed to reduce the
levels of crude fiber in coconut dregs. This study aims to analyze the effect of
variations in the fermentation time of coconut dregs waste by BSF larvae with
WRI, ECD analysis, optimum reduction percentage, final nutrient content of BSF
larvae according to SNI, and analyze the reduction of environmental factors using
spearman correlation. This study used a quantitative method, fermentation of
coconut pulp using EM-4 with a concentration of 3% for 3, 5, 7, and 9 days. The
efficiency of reducing crude fiber using EM-4 3% was highest in fermentation for
3 days, which was 36%, with a feeding frequency of 1 kg/day for 600 BSF larvae
for 15 days. The results showed that the highest WRI value was in R1 (3 days)
which was 5.01%, the highest ECD value was in R1 (3 days) which was 22.32%,
optimum reduction was recorded in R1 with 74.40%. The BSF larvae nutrient
content test showed good protein and fat levels in each reactor in accordance with
SNI (8920.3: 2016). Reduction is also influenced by the water content value, where
the water content decreases due to microorganism activity and increases due to
temperature increases.
