Kata kunci: Black Soldier Fly (BSF), Evaluasi, Pengelolaan, Sampah Organik.The organic waste management program using Black Soldier Fly (BSF) is one of the governments efforts to reduce the amount of organic waste in the city of Surabaya using BSF assistance that is able to reduce organic waste with a faster time compared to composting techniques. BSF is a species of fly that utilizes organic waste as food source. The organic waste used in this program is household waste transported from RT 7 and RT 8 RW 3 Jambangan with 260 houses. This study aims to describe the evaluation of organic waste management program using BSF in the pusat daur ulang Jambangan Kota Surabaya. This type of research is a qualitative descriptive study. The focus of the study is based on 5 indicators of policy evaluation according to Agustino which include: apparatus resources, institutions, facilities, infrastructure, and technology, financial, and regulation. Data analysis techniques are based on techniques according to Miles and Huberman. The results of the evaluation of the organic waste management program using the BSF in the pusat daur ulang Jambangan, namely: 1) apparatus resources, there is no job description for each officer, 2) institutional, fluent coordination, flexible discretion, democratic leadership patterns, and synergy has gone well, 3) facilities, infrastructure, and technology, all three aspects have been sufficient and able to support the implementation of the program, 4) financial, financial support from the DKRTH Surabaya can meet the costs of implementing the program, 5) regulation, this program does not have specific regulations, only have SOP as a guide to implementing the program. Thus it can be concluded that in the implementation of the organic waste management program using Black Soldier Fly (BSF) in the pusat daur ulang Jambangan there are still some weaknesses, the need for a review of job descriptions and making job descriptions of each officer. Consistency is needed in implementing the program by carrying out the program routinely to reduce the amount of organic waste accumulation, and to inventory the facilities and infrastructure that are owned to facilitate maintenance. Review and revise SOP to avoid mistakes in program implementation. Keywords: Black Soldier Fly (BSF), Evaluation, Management, Organic Waste.

The sustainable utilization of black soldier fly (BSF) for recycling organic waste into nutrient-rich biomass, such as high-quality protein additive, is gaining momentum, and its microbiota is thought to play important roles in these processes. Several studies have characterized the BSF gut microbiota in different substrates and locations; nonetheless, in-depth knowledge on community stability, consistency of member associations, pathogenic associations, and microbe–microbe and host–microbe interactions remains largely elusive. In this study, we characterized the bacterial and fungal communities of BSF larval gut across four untreated substrates (brewers' spent grain, kitchen food waste, poultry manure, and rabbit manure) using 16S and ITS2 amplicon sequencing. Results demonstrated that substrate impacted larval weight gain from 30 to 100% gain differences among diets and induced an important microbial shift in the gut of BSF larvae: fungal communities were highly substrate dependent with Pichia being the only prevalent genus across 96% of the samples; bacterial communities also varied across diets; nonetheless, we observed six conserved bacterial members in 99.9% of our samples, namely, Dysgonomonas, Morganella, Enterococcus, Pseudomonas, Actinomyces, and Providencia. Among these, Enterococcus was highly correlated with other genera including Morganella and Providencia. Additionally, we showed that diets such as rabbit manure induced a dysbiosis with higher loads of the pathogenic bacteria Campylobacter. Together, this study provides the first comprehensive analysis of bacterial and fungal communities of BSF gut across untreated substrates and highlights conserved members, potential pathogens, and their interactions. This information will contribute to the establishment of safety measures for future processing of BSF larval meals and the creation of legislation to regulate their use in animal feeds. ; The Canadian International Development Research Centre (IDRC) and the Australian Centre for International ...

The cultivation of maggot Black Soldier Fly (BSF) is a bioconversion technology of organic matter that can be one solution to the problem of organic waste. This study aims to examine aspects of organic waste management through BSF Medan maggot cultivation, including operational technical, financing, institutional, regulatory and community and government participation aspects. This research is a descriptive observational study with an exploratory study approach using the interview method. Descriptive and quantitative data processing and analysis. Based on operational technical aspects, maggot cultivation has succeeded in converting organic waste into a source of animal feed protein and reducing the amount of organic waste. The amount of organic waste that is managed is 90kg/day with an effectiveness of 0.013% the total domestic waste in Medan. The financing and institutional aspects of waste management are managed in an organized manner through a cooperative body, namely the Primary Waste Management Cooperative (PKPS) Medan. The regulatory aspect that is used as reference is Medan Mayor Regulation No. 26 of 2019. Aspects of community participation directly from members of the cooperative and the Laucih wholesale market trader in Medan City. This bioconversion technology is able to overcome the problem of waste in an effort to reduce organic waste.

The Joint Business Group of Pondok Maggot Marelan which is located in the Village of Falls, District of Medan Marelan, Medan City is a business group that carries out the cultivation of Black Soldier Fly (BSF) which has been able to produce maggot larvae of about 60 kg per week. The existence of this group is very helpful for the community and the local government in managing the existing organic waste. The increase in the production of maggot larvae is hampered because the capacity of the maggot house is still too small. In addition, the processing of existing maggot larvae is also still limited, namely as chicken or duck feed. This service aims to assist partners in increasing and managing the production of existing maggot larvae. Making maggot houses and training in making floating fish feed using maggot larvae is also important as an alternative in post-harvest management of maggot larvae. This service output program includes fish feed training services, making BSF maggot houses with temperature and humidity sensors, activity videos, and scientific articles. BSF cultivation counseling and training activities have been carried out well. The conclusion of this activity is an increase in maggot production due to the addition of BSF maggot biopond houses. In addition, partners also gain new knowledge in the form of how to manage BSF maggots into floating fish feed that can be used in freshwater fish farming.

Black soldier fly (BSF, Hermetia illucens), may be a reliable source of animal protein, fats, calcium, lysine, etc. This makes it possible the products obtained by this insect to become substitutes (partly orentirely) of the soybean and fish meal. First of all, however, different issues should be solved to react on the future increase in the demands for such kind of products as feed. This means to dramatically change the technology of manufacturing and to introduce regulatory legislative frameworks in which this industry to be developed, guaranteeing its safety for the customers. This is necessary despite the fact that in BSF larvae such preconditions due to the biological and cycle characteristics are not observed, as naturally it excludes the transfer of pathogens from the bed because of the disconnection of the composted matter at the prepupae stage. This is a result of natural migration, during which the larvae are self-cleaning mechanically and chemically, while emptying their gastrointestinal tract. Additional reliability is also assured by the fact that the adult insect does not feed, does not lay eggs directly in the compost and is not a carrier of infectious and parasitic diseases. Since it is a natural resident of the poultry manure, it can also be successfully used for its processing, on the one hand reducing the volume, and on the other decreasing the concentration of the pathogenic microflora in it, which naturally leads to its decontamination. In terms of origin, some drawbacks have also been identified, however, the effect of which can easily be neutralized by developing the systems used and regulating the composition of the food substrate.

Using insects, notably black soldier fly (BSF), is becoming one of the emerging technologies to valorize agrifood waste into high-value products, such as proteins for animal feed. Its market is expected to grow more rapidly following the new European legislation extending larvae protein use in poultry farming. The anticipated increase in larvae protein also results in a parallel increase in frass, a residue leftover after rearing the larvae and selling as a biofertilizer. Little is known about the impacts of frass made from different feedstocks used for raising the larvae on plant growth and soil quality. We set up an incubation and pot experiment to understand their effect on plant growth and soil quality and tested seven frass fertilizers made from various types of food waste and anaerobic digestate and potato pulp as reference materials using maize as a test plant. We found that the effect of frass on N availability and soil microbial quality significantly (p < 0.05) varied depending on the feedstock used for rearing the BSF larvae. N immobilization occurred up to more than 70 days, and 4–20% net N was released at the end of the 103-day-long experiment. In line with N availability dynamics, most of the frass treatments did not significantly increase the plant growth. All frasses significantly increased the microbial biomass C and enzyme activities. About 56–70% of the applied C in frass is estimated to be stable in the soil. Our data confirm that frass is a valuable product to improve soil quality but need to be applied with N sources that are readily available to avoid nutrient shortage during plant growth.

AbstractBiowaste treatment with Black Soldier Fly (BSF) larvae is an alternative option for organic waste valorization. Its environmental impacts should be assessed and compared with conventional treatment options. The research aims to evaluate the treatment of organic fraction of municipal solid waste (OFMSW) with BSF larvae through a life cycle assessment (LCA). This study employed data inventories from literature and aimed to provide a wide range of production parameter values to identify the potentialities of BSF treatment in the best-case and worst-case scenarios. The SimaPro9, the database Ecoinvent3.5, and the impact assessment method IMPACT 2002+ have been employed for the analysis. A sensitivity analysis of relevant parameters was conducted, considering the avoided impacts that can be obtained thanks to the exploitation of larvae proteins for bioplastics or fishmeal production. Research findings highlight six main environmental impact indicators: respiratory inorganics (kg PM2.5-eq), ozone layer depletion (kg CFC-11-eq), terrestrial ecotoxicity (kg TEG soil), land occupation (m2 organic arable), global warming (kg CO2-eq), and non-renewable energy (MJ primary). The most relevant process generating impacts is BSF breeding, followed by boiling, storage, and OFMSW treatment. The environmental performance is better when the conventional fishmeal substituted, thanks to BSF larvae production, is made from areas 10,000 km far, implementing a 100% renewable energy scenario, reducing the energy consumption by 50%, increasing the lifespan of the equipment to 15 years, and products are employed locally. The current study represents the first attempt to evaluate the global higher or lower environmental impact scenario related to OFMSW treatment through BSF larvae.
Graphical Abstract

European legislation permits the inclusion of insect proteins in pet and aquaculture diets. Black soldier fly larvae (BSF) are one of the most actively produced species due to their low environmental impact and nutritional characteristics. BSF protein derivatives (proteins and protein hydrolysates) contain a substantial amount of low molecular weight peptides that are known to possess antioxidant potential. In this study, the in vitro antioxidant potential of commercial BSF proteins and protein hydrolysates was investigated for (1) radical scavenging activity, (2) myeloperoxidase activity modulation, and (3) neutrophil response modulation. Chickenmeal and fishmeal are commonly used in pet food and aquaculture formulations. Hence, both were used as industrial benchmarks during this study. The results indicate that fishmeal and chickenmeal are ineffective at suppressing the oxidative damage caused by neutrophil response and myeloperoxidase activity. Fishmeal and chickenmeal even exhibit pro-oxidant behavior in some of the models used during this study. On the other hand, it was found that BSF protein derivatives could be effective in protecting against the cellular damage resulting from neutrophil and myeloperoxidase activities. The outcomes of this study indicate that BSF protein derivatives could be potentially included in pet food and aquaculture feed formulations as health-promoting ingredients.

SIMPLE SUMMARY: In European countries, black soldier fly larvae (BSF) proteins are gaining rapid acceptance as high value protein ingredients in pet food and aquaculture feed formulations. BSF protein derivatives (proteins and protein hydrolysates) contain a significant share of short-chain peptides that are known to possess antioxidant behavior. In the present study, the in vitro antioxidant potential of BSF protein derivatives was analyzed using five different models. Chickenmeal and fishmeal are commonly used in pet food and aquaculture feed formulations and hence were used as industrial benchmarks. The results obtained during this study show that chickenmeal and fishmeal offer little or no advantage in protecting animal cells against the oxidative damage resulting from neutrophils and myeloperoxidase response. Moreover, chickenmeal and fishmeal even show pro-oxidant responses in some of the models tested during this study. It was found that the BSF protein derivatives used in this study could be effective in protecting the animal cells from oxidative damage as a consequence of immune response.
