Abstract

Abstract Public awareness of waste management has increased over the past decade. The government has carried out numerous of waste management outreach from the national level to the sub-district level, which is the separation of organic and non-organic waste. Bukit Pinang Village is one of the sub-districts located in Samarinda Ulu District, Samarinda City, East Kalimantan. RT 19 is one of the RTs in Bukit Pinang Village where several residents have awareness about the separation of organic and non-organic household waste. However, the knowledge about organic waste management is still inadequately implemented. This was seen from the fact that many residents still throw it away in final disposal sites and some residents even burn their household waste, which of course disrupts air quality. Through this Community Science Program, counselling was provided on the management of organic household waste using a zero waste-based system that has broad and long-term benefits such as the plantation sector in a simple (minimalist) concept to housewives in RT 19. Participants were equipped with knowledge about improving the processing of household waste into more useful products, such as minimalist gardens and compost, so that local residents can manage their own waste while also having minimalist production gardens.

Abstract

Edible film is a thin, consumable layer that serves as environmentally friendly packaging. One of its potential raw materials is chitosan derived from blue crab shells. This study aims to determine the effect of gelatinization temperature (30, 40, 50, 60, and 70 °C) and drying temperature (40, 50, 60, 70, and 80 °C) on the characteristics of edible films to obtain products that meet quality standards. The best result was achieved at a gelatinization temperature of 70 °C, producing a film with a thickness of 0.20 mm, moisture content of 14.27%, tensile strength of 38.82 MPa, and elongation of 90.58%. During the drying stage, with the gelatinization temperature maintained at 70 °C, the optimal condition was obtained at 80 °C, resulting in a film with a thickness of 0.15 mm, moisture content of 12.36%, tensile strength of 18.39 MPa, elongation of 119.83%, and 100% biodegradability. Increasing both the gelatinization and drying temperatures improved the physical properties and water resistance of the edible film. The elongation value met the JIS Z-1707:2019 grade 4 standard, and the biodegradability complied with SNI 7188.7:2016, although the tensile strength remained below the standard requirement.
