Abstract

The feed industry faces significant challenges in managing organic waste and ensuring a sustainable supply of animal protein. The implementation of circular economy principles through bioconversion using Black Soldier Fly (BSF) larvae offers an innovative solution to reduce waste while generating high-value biomass. This study aims to evaluate and compare the performance of BSF larvae in processing two types of waste substrates—fish scale waste (P1) and canteen food waste (P2)—to identify the most optimal feeding medium. A quantitative experimental method with a comparative design was conducted within an operational feed production environment. Bioconversion effectiveness was assessed using three key indicators: bioconversion percentage, Waste Reduction Index (WRI), and Feed Conversion Ratio (FCR). The results demonstrated the superior performance of canteen food waste (P2) as a feeding substrate. P2 achieved the highest bioconversion rate at 96.34%, surpassing P1, which reached 78.52%. Additionally, P2 exhibited a faster decomposition rate with a WRI value of 13.98% (P1: 12.79%) and better feed efficiency, as indicated by a lower FCR value (1.04) compared to P1 (1.27). These findings confirm that canteen food waste (P2) provides the most favorable substrate for enhancing BSF larval performance and optimizing organic waste bioconversion.

Abstract

The increasing population and intensity of food service activities have contributed to a substantial rise in cafeteria waste volume. This organic waste, characterized by its complex nutrient and moisture content, poses serious environmental challenges, particularly through greenhouse gas emissions resulting from conventional landfill practices. Within the framework of the circular economy, this study explores the potential of bioconversion of cafeteria organic waste using Black Soldier Fly (BSF) larvae as an innovative and sustainable waste management solution. A quantitative experimental method was employed to evaluate the efficiency of waste mass reduction and to analyze the added value of the resulting BSF larvae as an alternative feed ingredient. The findings demonstrate a high effectiveness of BSF larvae in reducing waste volume, as indicated by an optimal Waste Reduction Index (13.98%), an efficient bioconversion rate (96.34%), and a favorable Feed Conversion Ratio (1.04). The process proved to be rapid and cost-efficient, with an operational cost of approximately IDR 3.5 million per month, generating both economic and environmental value.

Abstract

The transformation of a start-up business for lemongrass soap products requires in-depth research for competitiveness and sustainability. This study aims to analyze the development of a start-up business producing lemongrass-based solid bath soap and its sustainability strategy in women's farmer group X. The approach used includes SWOT analysis, calculation of Cost of Goods Sold (COGS), and Business Model Canvas (BMC) to assess internal strengths, external opportunities, production cost efficiency, and the design of a sustainable business model. The results of the study show that the quantitative strategy analysis (IE/SWOT Matrix) places KWT X at coordinates (1.65; 1.15), which falls in Quadrant I (Aggressive). This position indicates that the company or business (KWT) has strong internal strengths (X Score: 1.65 > 0) and is in the midst of large external opportunities (Y Score: 1.15 > 0). So, KWT X's business is in a very favorable condition. The COGS calculation results show a production cost per unit of Rp9,000, with an ideal selling price of Rp12,500–Rp13,000 per unit to be competitive in the market. In addition, the implementation of the nine BMC elements confirms that KWT X has a strong business foundation through strategic partnerships, product diversification, and digital marketing. Product innovation, cost efficiency, and strengthening human resource capacity are key factors for the sustainability of the lemongrass-based herbal soap business.
