Abstract

Black Soldier Fly (Hermetia illucens) is an insect with considerable potential for organic waste bioconversion and sustainable protein production. This study aimed to evaluate the effect of fermented coconut dregs combined with fermented chicken manure on the size of prepupae, pupae, adult BSF, and abdominal development. The research was conducted using a laboratory experimental method with a Completely Randomized Design (CRD) consisting of five substrate formulations. Parameters observed included body length, width, and weight of prepupae, pupae, adult BSF, and abdominal dimensions. Data were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level. The results showed that the different combinations of fermented coconut dregs and fermented chicken manure did not significantly affect (P > 0.05) the length, width, or weight of prepupae, pupae, adult BSF, or abdominal size. Although numerical differences were observed among treatments, the variation was not statistically significant. The treatment containing 90% fermented coconut dregs and 10% fermented chicken manure tended to produce higher values for several prepupal and pupal growth parameters, while the treatment containing 80% fermented coconut dregs and 20% fermented chicken manure tended to produce larger abdominal dimensions. These findings indicate that the tested substrate combinations were able to support BSF development, but none provided a statistically superior effect on morphometric characteristics. Further studies with broader nutritional variations and larger sample sizes are recommended to better understand the influence of substrate composition on BSF growth and development.

Abstract

The increasing generation of organic waste has highlighted the need for sustainable bioconversion technologies, including the use of Black Soldier Fly (Hermetia illucens) larvae as efficient decomposers. This study evaluated the effects of fermented coconut pulp (FCP) and fermented rumen contents (FRC) as rearing substrates on the morphometric characteristics of BSF prepupae, pupae, and imago. A Completely Randomized Design (CRD) with five substrate formulations and 40 replications per treatment was applied. Morphometric parameters, including body length, body width, body weight, and adult abdominal dimensions, were analyzed using one-way ANOVA. The results indicated that different substrate formulations did not significantly affect any morphometric parameter (P > 0.05). Nevertheless, numerical variations were observed, with the substrate containing 85% FCPand 15% FRC (T3) tending to produce greater body dimensions, while the substrate containing 80% FCPand 20% FRC (T4) showed the greatest abdominal width. Overall, fermented coconut pulp, either alone or combined with fermented rumen contents, provided comparable nutritional conditions that supported normal BSF growth and development. These findings suggest that both organic waste materials can serve as promising alternative substrates for sustainable BSF cultivation and organic waste bioconversion.
