Pengelolaan Sampah Berbasis Edukasi dan Teknologi Tepat Guna melalui Pembuatan Incinerator di Desa Krawang, Kecamatan Natar, Kabupaten Lampung Selatan

Abstract

Waste management problems in Sidorejo Hamlet, Krawang Sari Village, Natar District, South Lampung Regency, are characterized by waste accumulation, inadequate source separation, and limited facilities for handling residual waste. This community service program aimed to improve waste-sorting practices and provide an alternative method for handling residual waste through a simple incinerator. The program employed an educational-participatory approach and direct practice involving 61 fourth-grade students from Classes IV A and IV B of UPTD SD Negeri 2 Krawang Sari and a local waste management operator. Activities included initial observation, education on organic and inorganic waste, waste-sorting practice, provision of separate bins, incinerator construction, functional testing, user assistance, and field evaluation. Approximately 20 days after the educational activities, observations showed that students were able to distinguish organic from inorganic waste and use the labeled bins appropriately. The incinerator functioned for residual waste management and was used six times within approximately one week after construction. Residual waste accumulation also appeared to decrease, while waste management became more organized. These findings suggest that integrating environmental education, sorting facilities, user assistance, and appropriate technology can support community-based waste management. However, the findings remain descriptive because waste reduction, combustion temperature, air quality, and emissions were not quantitatively measured. Long-term monitoring is needed to assess sustainability and environmental safety.
