Abstract

Tempe is a traditional Indonesian food product obtained through a fermentation process that utilizes the activity of molds from the genus Rhizopus sp. on soybeans. Oxygen availability plays a crucial role in tempe fermentation, as Rhizopus sp. is an obligate aerobic mold that requires oxygen for optimal growth. This study was conducted to examine the extent to which oxygen availability affects the growth of Rhizopus sp. during the tempe fermentation process, while also serving as a practical application of traditional biotechnology in daily life. The study employed an experimental design with three different packaging treatments: banana leaves, perforated plastic, and non-perforated plastic. Fermentation took place over 48 hours at a temperature of 30–32°C. Observations of mycelium growth were conducted every 12 hours, focusing on several indicators: color, hyphal density, and the surface area covered by mycelium. These observations were supplemented by an assessment of tempeh’s physical quality, encompassing color, aroma, texture, and firmness. Based on the research results, it was found that the use of banana leaf packaging produced the densest, most even, and purest white mycelium growth, while also yielding tempeh with the highest physical quality and nutritional content compared to other types of packaging. Perforated plastic packaging yielded fairly good results, whereas non-perforated plastic packaging produced tempeh of the lowest quality due to restricted air circulation. It can be concluded that oxygen availability has a significant effect on the growth of Rhizopus sp. and the quality of the resulting tempeh. The better the air circulation within the packaging, the more optimal the fermentation process and the quality of the resulting tempe.

Abstract

Waste problems in the school environment remain a challenge, particularly regarding students’ low awareness in sorting organic and non-organic waste. The lack of understanding about the types of waste and their environmental impacts often results in mixed waste that is not managed optimally. This community service activity aims to increase students’ awareness of the importance of waste sorting through a socialization program conducted in the school environment. The program was implemented through material presentations and interactive discussions. The results indicate an improvement in students’ understanding of the differences between organic and non-organic waste, as well as the development of a caring attitude toward maintaining school cleanliness. Through this activity, it is expected that positive habits in disposing of and sorting waste properly will be established, thereby creating a clean and sustainable school environment. This article is limited to its implementation at SMA El-Syihab Bandar Lampung by PLP-KKN students, Period 1, 2026. This article also contributes to academic knowledge as well as practical strategies for implementing Goal 12 of the Sustainable Development Goals (SDGs).
