Poultry farming in Indonesia needs continuous development to meet the demand for eggs from the community. Running a layer chicken farm poses its challenges, including managing layer chicken waste, such as chicken manure, to prevent environmental harm caused by odor and the spread of diseases through flies. Additionally, a major challenge for layer chicken farming is the significant cost of feed provision, as the cost of chicken feed can account for 60-70% of the overall production costs in poultry farming. The high use of raw materials such as fish meal, fish oil, soybean meal, and other grains in chicken feed, which is increasing, also leads to limitations in supply and price increases, affecting the cost of commercial chicken feed. To address these challenges and ensure the sustainability of layer chicken farming, it is necessary to explore alternative chicken feed sources. The larvae of Hermetia illucens, known as Black Soldier Fly (BSF), have been widely used as a bioconversion agent for various wastes and are easy to cultivate in Indonesia. According to several studies, Hermetia illucens larvae have been successfully utilized as an additive in chicken feed, replacing soybean meal by 10-20% or up to 50% of soybean meal in chicken feed. Integrating layer chicken farming and BSF larva cultivation can provide benefits such as reducing feed costs and decreasing the amount of organic waste by processing it with BSF larvae into organic fertilizer ”kasgot”. The integrated production system of Isa Brown layer hens with Black Soldier Fly (BSF) larvae production as a supplementary feed is expected to reduce feed costs and enhance the value of waste from layer hen farming, turning it into an additional income source for the farm. This system aims to establish a sustainable business model. In this egg production system, an alternative approach is applied, involving the farming of Isa Brown layer hens with a combination of commercial chicken feed and BSF larvae obtained from independent BSF farming. This production system is designed for a capacity of 4,500 layer hens over a period of 104 weeks per production cycle. This alternative demonstrates the highest Revenue Cost (R/C) Ratio, which is 1.90. This means that for every unit of the cost incurred, there is a revenue of 1.90 units. Preliminary design of the integrated production system of Isa Brown layer hens with Black Soldier Fly (BSF) larva production as a supplementary feed can yield the following products: chicken eggs priced at Rp26,000.00 per kg, culled layer hens at Rp40,000.00 per head, chicken manure fertilizer at Rp11,500.00 per 25 kg bag, and “kasgot” fertilizer at Rp15,000.00 per kg. The initial investment required is Rp2,038,100,000.00. The amount of investment changes each year depending on the useful life of the equipment used during the production cycle. The production capacity per cycle for the layer hen subsystem is 120,145.41 kg of chicken eggs with revenue of Rp3,123,780,660.00, 105,879.13 kg of chicken manure fertilizer with revenue of Rp48,704,401.48, and 4,500 culled layer hens with revenue of Rp180,000,000.00. The production capacity of BSF during one chicken farming cycle is 62,521.20 kg of BSF larvae, which is entirely used for chicken feed, and 79,572.44 kg of “kasgot” fertilizer with revenue of Rp1,196,309,142.50. The business will start to generate profits upon reaching the Break Even Point (BEP) for chicken egg products, which is Rp1,402,774,345.59, with a BEP unit of 53,952.86 kg. The BEP for chicken manure fertilizer products is Rp8,380,652.18, with a BEP unit of 728.75 bags of 25 kg each. The BEP for culled layer hen products is Rp27,575,464.64, with a BEP unit of 689.39 heads. The BEP for “kasgot” fertilizer products is Rp199,850,948.37, with a BEP unit of 13,323.40 kg. The investment capital for the preliminary design of this business system will be recouped in 3 years, 0 months, and 4 days. The Net Present Value (NPV) obtained is Rp1,465,389,330.72. The company’s Internal Rate of Return (IRR) is 29.78%, and the Benefit-Cost (B/C) Ratio is 1.72. Based on these analyses, the preliminary design of the Isa Brown layer hen egg production system integrated with Black Soldier Fly (BSF) larvae production as a supplementary feed is considered feasible for implementation.
