Abstract

This study aimed to evaluate the physicochemical properties and fatty acid methyl ester (FAME) profile of Hermetia illucens (BSF) maggot extract as a potential sustainable ingredient for animal feed. Lipid extraction was performed using a modified Bligh and Dyer method by substituting chloroform with n-hexane to ensure safer and environmentally friendly processing. Proximate analysis revealed that BSF maggots contained 29.36% crude protein, 43.76% crude fat, 9.27% ash, 19.94% crude fiber, and a low moisture content of 3.06%, indicating high nutritional density and storage stability. XRF and qualitative tests confirmed significant mineral content, particularly CaO, K?O, and P?O?, with no detectable heavy metals or harmful contaminants, supporting their safety for feed applications. Microscopic analysis showed particle sizes ranging from 2,000-10,000 nm, classifying the material as a nanostructured biomass. The FAME profile demonstrated a diverse composition dominated by 9-octadecenoic acid (10.92%), triacontane (8.87%), octadecanoic acid (7.65%), and heptacosanoic acid (7.17%). Key medium- and long-chain fatty acids such as dodecanoic acid (C12:0), elaidic acid (C18:1), and stearic acid (C18:0) were also detected, indicating the suitability of BSF lipids as an energy-dense feed component with oxidative stability. Overall, the biochemical and structural characteristics obtained in this study highlight BSF maggots as a promising, nutrient-rich, and environmentally sustainable ingredient for animal feed formulations.

Abstract

Learning ecosystem material can be taught in line with efforts to realize the Sustainable Development Goals, one of which is the point of Life on Land. Learning media plays a crucial role in facilitating effective learning and offers advantages, especially in terms of flexibility and interactivity. This development aims to produce a website-assisted learning product, the Eco-Explorer Game, which is effective in improving the dimensions of mutual cooperation and cognitive learning outcomes. The development process follows the Lee & Owens model, which consists of five stages: analysis, design, development, implementation, and evaluation. In the implementation stage, this study used a pre-experimental design with a one-group pretest-posttest technique, with a sample consisting of 36 tenth-grade students at SMAN 1 Singosari. Quantitative data were collected through two main instruments: pretest and posttest scores to measure cognitive learning outcomes, and observation sheets equipped with a quantitative assessment rubric to measure the dimensions of mutual cooperation (collaboration, caring, and sharing). The data analysis technique to measure the improvement of both variables used the N-Gain test. The collected data shows that the game is proven to be effective in improving the dimensions of mutual cooperation and students' cognitive learning outcomes as indicated by the increase in the average achievement results of each indicator both in the dimensions of mutual cooperation (from the initial 56.1 to 88.7) and also cognitive learning outcomes (from the initial 66.8 to 87.7). The N-Gain score obtained from the observation sheet for the dimensions of mutual cooperation shows a high score of 0.7. Furthermore, cognitive learning outcomes show an N-Gain score of 0.62, which is included in the moderate category. Based on these findings, it can be concluded that the Eco-Explorer Game is very effective in improving the dimensions of mutual cooperation of students and is quite effective in improving their cognitive learning outcomes.
