Abstract

The problem of plastic waste is a serious issue in Indonesia, especially in Tanjung Village, Bima City, where waste management is still less than optimal. One solution implemented is the use of Ecobrick, a plastic waste management technique by filling used bottles with plastic until they are solid and hard. This program involves socialization and training at SDN 29 Tanjung and SMPN 13 Bima City, where students are taught how to process plastic waste into products with economic value such as furniture. The results of this program show that Ecobrick is effective in reducing the volume of plastic waste while increasing public awareness of the importance of waste management. The use of Ecobrick not only helps maintain environmental cleanliness but also provides economic benefits and has the potential to reduce negative environmental impacts such as coastal abrasion. It is hoped that this program can be the first step in forming new habits in the community related to waste management.

Abstract

Krisis energi dan dampak lingkungan akibat penggunaan bahan bakar fosil mendorong pencarian solusi energi terbarukan yang ramah lingkungan. Pengabdian ini bertujuan memanfaatkan biogas sebagai alternatif energi di Rumah Qur'an At-Tazkiyah, Sembalun, Lombok Timur. Sistem monitoring tekanan dan laju aliran biogas dirancang dan diimplementasikan untuk memantau kinerja sistem secara real-time. Alat monitoring yang terintegrasi dengan platform Blynk memungkinkan pengambilan data setiap menit, memberikan gambaran mengenai performa sistem. Hasil pantauan menunjukkan bahwa tekanan biogas mengalami tren penurunan, sedangkan massa dan laju aliran biogas menunjukkan variasi yang dipengaruhi oleh ketersediaan bahan baku, terutama kotoran sapi. Laju aliran yang relatif rendah dapat mengakibatkan efisiensi pembakaran yang kurang optimal dan meningkatkan emisi karbon. Kesimpulan dari pengabdian ini menegaskan bahwa meskipun terdapat tantangan dalam pengelolaan biogas, penerapan teknologi monitoring yang efektif dapat meningkatkan kinerja sistem dan membantu dalam pengambilan keputusan yang lebih baik. Rekomendasi untuk perbaikan sistem diharapkan dapat meningkatkan efisiensi produksi biogas, menyediakan sumber energi yang berkelanjutan, serta memberikan kontribusi pada pengurangan biaya operasional dan keberlanjutan lingkungan di masyarakat.

Abstract

Snake envenomation is classified as a medical emergency that can result in significant tissue necrosis and potentially fatal outcomes. The Sembalun Bumbung region, situated in a highland or mountainous area and surrounded by dense forest, is considered a high-risk zone for snakebite incidents. The local population, particularly in Sembalun Bumbung, demonstrates limited knowledge regarding appropriate first aid measures for snakebite cases, thereby necessitating a public health intervention aimed at increasing community awareness, with a specific focus on children. a health education outreach was conducted in a single session at MTs NW Gunung Pangsor, involving 50 participants. Educational content was delivered by subject matter expert through a powerpoint presentation, supplemented by a live demonstration using a real snake. The session lasted approximately 45 minutes and was followed by an interactive question-and-answer segment. To assess the participants comprehension, an oral quiz was administered to 10 individuals selected at random. All participants provided accurate and appropriate responses. Consequently, the educational intervention was deemed effective in improving participants knowledge regarding the identification of venomous and non venomous sankes, as well as evidence based strategies for the prevention and initial management of snakebite envenomation
