12. Dragon fruit peel waste treatment by black soldier fly larvae (hermetia illucens) with different mixture rates

Abstract

Black soldier fly larvae (BSF) is considered as one of the biological filters in treating different sources of organic waste to create environmentally and economically useful products. This research applies the BSF in the treatment of dragon fruit peel with different nutrient mixing ratios with industrial bran, which are 95:5, 90:10, 85:15, respectively. The results show that the BSF larvae have different growth capacity and reproduction ability in different substrate ratios. In which, the waste treatment efficiency at 85:15 ratio is the highest (71.89 %) and the lowest efficiency is at 95:5 ratio (49.37 %). This can be considered as an efficient model of organic waste treatment with low investment cost and easy to apply to family or hamlet scale in rural areas.
