Eksplorasi Potensi Limbah Imago Ulat Sutera Liar Attacus atlas (Lepidoptera: Saturniidae)

Abstract

Wild Silkworm Attacus atlas is an Indonesian native germplasm from Aceh to Papua. Cultivation of wild silkworm Attacus atlas has started in line with the high market demand on the caterpillar cocoon. The purpose of this study was to determine the potential of imago waste produced by cultivation of wild silkworm Attacus atlas as a source of alternative feed ingredients and the potency as antimicrobial. Proximate analysis was done to find out nutrition in imago of Attacus atlas, antimicrobial testing using the disk method. The results of the proximate analysis test imago silkworm Attacus atlas shows that the imago contains 75.57% protein, 5.94% fat, 3.80% ash, and 14.64% crude fiber from dry matter. Attacus atlas imago extract is brown, gel, fat as a potential source of animal fat. Antimicrobial test from 96% ethanol extract of imago Attacus atlas with the disk method showed no antibacterial activity against Escherichia coli, Pseudomonas, Streptococcus, and Staphylococcus.
