The Digestibility of Banana Peel and Testa coconut and Its Effects on the Growth and Mortality of Black Soldier Fly Larvae (Hermetia illucens) at Constant Feeding Rates

Abstract

Organic waste produced by economic activities may create health, aesthetic, and economic problems. One of the approaches applied to solve this problem is the utilization of decomposer macrofauna to decompose the waste. One of the decomposers with great potential is Black Soldier Fly larvae (Hermetia illucens) that can consume various types of organic wastes and converts it into biomass with high protein and lipid content. In this study, banana peels and coconut testa had been fed to the larvae at 200 mg/larvae/day as the objects that represented organic wastes with low fiber content and high fiber content respectively. The purpose of this study was to observe the growth and efficiency of BSF larvae in decomposing those wastes. The analysis was conducted on some parameters such as the growth and consumption rate, the efficiency of conversion of digested (ECD), waste reduction index, and mortality rate. The results showed that BSF larvae THAT consumed banana peel had a higher final weight (58.24 mg), growth rate, and consumption rate while the mortality rate was lower than BSF larvae that consumed coconut testa. The ECD of the larvae group that consumed banana peel was higher than the larvae group that consumed coconut testa. The waste reduction index of banana peel was higher than coconut testa (1.5 and 1.4, respectively). The larvae that consumed coconut testa had a longer pupation period (9±1,75 days) compared to the larvae that consumed banana peel. Based on this result, it can be concluded that the fiber content of organic waste affected the decomposition rate and growth of BSF larvae.

Enhancement of fruit byproducts through bioconversion by Hermetia illucens (Diptera: Stratiomyidae)

“…Meneguz et al (2018) and Leong et al (2016) calculated these indices on wet basis; comparing their results with ours, also in this case, our study obtained better performances. Low WRI and ECD values were recorded with substrates with low water content (Yusup et al, 2020), confirming that the substrate moisture content plays an important role in the potential of BSFL to feed on a given substrate and their food absorption (Putra et al, 2020). The moisture content of our substrates, ranging from 82% in the standard diet to 89% in the strawberry substrate, probably assured the right degree of humidity for BSFL development.…”

Effect of Macronutrient Combination on Survivorship, Growth, and Nutritional Content of Black Soldier Fly Larvae (Hermetia illucens)

“…Lalat BSF tersebar luas mulai dari daerah tropis hingga temperata (Čičková et al 2015). Lalat ini memiliki kemampuan untuk mengolonisasi berbagai jenis sumber daya mulai dari sisa buah-buahan dan sayuran (Kinasih et al 2018;Putra et al 2020), limbah makanan (Diener et al 2011;Kim et al 2021), hingga kotoran hewan dan manusia (Awasthi et al 2020;Oonincx et al 2015). Beberapa benefit dari pemanfaatan larva BSF sebagai agen biokonversi antara lain (1) larva dari lalat BSF diketahui mampu mengonversi 50% limbah yang diberikan menjadi biomassa tubuh yang tinggi protein dan lemak sebagai bahan baku bagi pakan hewan (Cummins et al 2017;Wang & Shelomi 2017;Dalle Zotte et al 2018;Onsongo et al 2018), (2) residu yang dihasilkan dapat berperan sebagai pupuk organik (Liu et al 2020), (3) proses penguraian melepaskan emisi gas rumah kaca lebih rendah dibandingkan produk yang dihasilkan dari proses penguraian limbah organik oleh mikroorganisme (Mertenat et al 2019;Parodi et al 2020) dan (4) menurunkan kemungkinan limbah menjadi lokasi dari pertumbuhan dari bakteri patogen (Lalander et al 2013;Q.…”

Characterization of Chitinolitic Bacteria from Hermatia illucent Larvae Waste: Antifungal Activity, Hydrolytic Enzyme, and Phosphate-Potassium Solubilization

“…BSF has several functions, such as being a source of biological agents, a protein source comprising 45-50%, capable of rapidly decomposing organic waste, mitigating odors, and promoting sustainability. Additionally, it serves as an alternative feed that can be directly converted into pellets (Masrufah et al, 2020;Putra et al, 2020). Through the utilization of maggots in bioconservation technology, it is possible to address critical environmental issues, specifically the reduction of organic waste originating from households, restaurants, industries, markets, and locations generating substantial organic materials like food scraps, leaf litter, and branches or wood.…”
