A co-conversion process using black soldier fly larvae (Hermetia illucens) and microbes was studied to convert rubber seeds into prepupal biomass from May to November 2016. De-oiled rubber seeds from West Bandung, Indonesia (cake to shell ratio of 2.5 wt%) was mixed with water (water to biomass ratio of 1.5-2.3 wt%) and pre-treated with two types of microbes; a liquid culture of Aspergillus niger (10 7 spore/ml) and a Biotaff solution containing consortium of microbes (10 7 cell/ml).

The highest prepupal biomass productivity of 124.2 g/m 2 .d on a dry basis with an assimilation efficiency of 28.7% and efficiency of conversion of digested feed of 25.9% was obtained when the larvae were cultivated using shade rate of 100% and fed with a substrate that had been pretreated with a Biotaff solution containing 10 7 cell/ml. At this condition, the prepupal biomass has a protein content of 28.6 wt% and a fat content of 28.3 wt% which mainly consists of lauric acid (24.6%), oleic acid (24.5%), linoleic acid (19.3%) and palmitic acid (18.4%). ~ 592 ~ Journal of Entomology and Zoology Studies feeding rate and larval height that affect the bioconversion of Reutealis trisperma seed for the production of protein and oil rich biomass. At the optimum conditions, the estimated productivity of the prepupal biomass is 123.4 g/m 2 .d with protein and fat content of 45 wt%, d.b. and 26.6 wt%, respectively [15] . The application of remaining biomass after the isolation of oil from rubber seeds as a substrate for the cultivation of BSFL has not yet been studied. Hence, the present study aimed to investigate the bioconversion of rubber seeds using BSFL assisted by microbes to increase the protein and oil content of the prepupal biomass.
