Abstract

This article discusses the implementation of sustainable education (Education for Sustainable Development, ESD) in managing organic waste in two schools, SMPN 1 Lawang Kidul and SMPN 1 Ujan Mas. Activities include material counseling, compost making practices, as well as evaluation using pretest and posttest methods to measure increases in student knowledge. The results showed a significant increase in students' knowledge level after the activity. Of the 30 participants at SMPN 1 Lawang Kidul, there was an increase of 121%. Meanwhile, the 37 participants at SMPN 1 Ujan Mas achieved an average increase in knowledge of 42.78%. This is because students at SMPN 1 Ujan Mas have higher initial knowledge abilities compared to students at SMPN 1 Lawang Kidul. This research highlights the importance of ESD in increasing students' environmental awareness and making a positive contribution to organic waste management practices in schools.

Abstract

Edible films are thin layers used to coat food products and can be consumed along with the product itself. Previous studies have utilized purple yam starch as a base material for edible films; however, these films exhibit limitations in terms of mechanical and barrier properties. This study aims to utilize purple yam mucilage to improve the mechanical and barrier properties of purple yam starch-based edible films.  The experimental design employed a randomized complete block design (RCBD) with five ratios of water to purple yam mucilage (1:0.5, 1:1, 1:1.5, 1:2, and 1:2.5). The results showed that increasing the proportion of purple yam mucilage improved the mechanical and barrier properties of the edible films, while reducing their solubility in water to as low as 33.23%.  The best film characteristics were achieved at a ratio of 1:2.5, with a thickness of 0.14 mm, a compressive strength of 3.73 × 10⁻⁴ MPa, a water vapor transmission rate (WVTR) of 21.94 g/m²·day, a transparency value of 8.33 %T/mm, and a solubility of 33.23%.
