“…In this investigation, RB emerged as a potentially effective dry substrate; however, numerous studies have highlighted its limitations. Previous examination of the proportion of RB mixed with coconut pulp residue revealed that BSFL did not thrive when the mixture contained over 50% (w/w) RB due to the resulting high substrate temperatures ( Muchdar et al, 2021 ). Similarly, and consistent with this study, RB could sustain BSF larval growth and rapid development when used at less than 25% (w/w) in the substrate due to its elevated protein content.…”

Background Controlling the substrate moisture is a significant challenge in black soldier fly (BSF) farming. Many substrates have a high moisture content, which results in a low BSF biomass and a high mortality. One potential solution involves incorporating dry substrates into the food mix to mitigate the excessive moisture. However, little information about the types and quantities of dry substrates is available. Methods Six different dry materials–rice husk (RH), rice bran (RB), rice husk ash (RHA), coconut coir dust (CC), rubberwood sawdust (RSD), and spent coffee grounds (SCGs)–were evaluated by combining with pure minced mixed vegetables in varying proportions (0%, 5%, 10%, 15%, 25%, and 50% by weight). This study encompassed both small-scale and medium-scale experiments to comprehensively assess the effects of the addition of each of these different dry substrates and their quantities on aspects of the development of BSF, such as BSF biomass, larval duration, mortality rates, adult sex ratio, and the moisture removal efficiency of each substrate mixture. Results Each dry substrate had specific properties. Although RB emerged as a favorable dry substrate owing to its nutritional content and substantial water-holding capacity, excessive use of RB (>15% by weight) resulted in elevated temperatures and subsequent desiccation of the substrate, potentially leading to larval mortality. In contrast, RH demonstrated the ability to support improved larval duration and growth, permitting its utilization in higher proportions (up to 50%). On the other hand, CC, RHA, and SCG are better suited for inclusion in BSF larval substrates in smaller quantities. Discussion Some dry substrates require a pretreatment process to eliminate toxic substances prior to their incorporation into substrate mixtures, such as CC and SCG. A potential alternative solution involves employing a combination of various dry substrates. This approach aims to enhance the substrate moisture control and subsequently improve the BSF rearing performance.

“…Sago and cassava dregs as well as rice straw were transformed into powders by grinding with a hammer mill and passing through an 80-mesh sieve [24]. Before grinding, all the materials were subjected to sun-drying for three days [25]. CMC, guar gum, carrageenan, and pea fiber were in the form of powder and no further treatments were applied.…”

The suitability of carrier materials for the entrapment of bacteria is an important factor in developing biofertilizers as it determines their functional properties during use and storage. This study examines the microscopic structure and entrapment properties of several potential carriers for biofertilizers. The carriers studied included rice straw, sago dregs, cassava dregs, gum, carrageenan, pea fiber, and carboxymethyl cellulose (CMC), all in powder form. The entrapment process was carried out by mixing the bacterial solution (10%) of Rhizobium, Azotobacter, Bacillus, and Methylobacterium with the carrier material by spraying and shaking followed by air drying. CMC and carrageenan exhibited a swollen structure when mixed with a bacterial solution, forming lumps. Gum, pea fiber, sago dregs, and cassava dregs swelled slightly, while rice straw demonstrated a non-swollen fibrous structure. The incorporated bacteria appeared entrapped inside the lumps and/or adhered to the surface of the lumps or fibrous particles. The largest number of bacteria was found in gum (log10 6 – log10 7) and pea fiber (log10 4 to – log10 7), followed by cassava dregs (log10 2 – log10 7), CMC (log10 2 – log10 6), sago dregs (log10 5) and rice straw (log10 3 – log10 4), while no bacteria was observed in carrageenan. Most bacteria survived in the carrier with swelling properties and loose structures. In conclusion, the microstructure of carrier materials provides information that can describe bacterial entrapment properties. This study gives important insight useful in formulating carrier materials for developing biofertilizers.

“…The principle of water content analysis is the distillation method, which is based on the direct measurement of the amount of water removed from the sample by evaporation (Deman et al 2018). Water content is based on the difference by weight sample that determines the actual moisture before and after drying (Muchdar et al 2021). Therefore, water in materials can be used as an index of stability during storage and a determinant of organoleptic.…”

Abstract. Anasya AD, Sugiarto, Mahajoeno E. 2022. Development of semi-artificial feed in the larva stage of the black soldier fly Hermetia illucens (Diptera: Stratiomyidae). Nusantara Bioscience 14: 188-194. Alternative food sources in fish farming besides pelleted feed are generally used, but many have also used biotic materials, larvae of the black soldier fly (Hermetia illucens L.). Maggot stadia larvae have a high protein content of more than 19%, could be mass-produced, are low-priced, and has a fast growth time. Therefore, high levels of protein and nutrients in maggots can be increased through suitable semi-artificial formulations. The purpose of this study was to determine the nutritional value of the semi-artificial feed recipe given and to determine the effectiveness of the semi-artificial feed recipe in increasing the nutritional value and survival of larvae. Data analysis used qualitative analysis with descriptive analysis method and quantitative analysis by determining the amount of increased nutritional value of H. illucens. The research method was carried out in several stages, including (i) insect rearing obtained 2nd generation of tillers (F2); (ii) manufacture of semi-artificial feed recipes; (iii) calculation of insect survival; (iv) measurement of larval mass weight after treatment; (v) testing of nutritional content value includes water content, fat content and protein content of H. illucens after treatment. Results of the evaluation larval survival after treatment were effective enough 100%, larval instar life phase was between 28-32 days, while the highest increase in the nutritional value of larvae water content was 45.90%, fat content 7.25%, and protein content 45.95%, the average increase in mass weight of larvae was 12.50%.
