Abstract

Limbah organik rumah tangga seperti nasi basi dan teh celup bekas sering dibuang tanpa pengelolaan, padahal berpotensi diolah menjadi pupuk cair organik. Namun, warga belajar di PKBM masih memiliki kesadaran dan keterampilan yang rendah dalam pemanfaatan limbah tersebut secara produktif. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan dan keterampilan warga belajar PKBM Salsabila Kota Langsa dalam mengolah limbah dapur menjadi pupuk cair berbasis prinsip zero waste. Metode pelatihan dilakukan secara partisipatif melalui ceramah, demonstrasi, dan praktik langsung. Pengabdian dilakukan pada 30 orang warga belajar pada PKBM Salsabila Kota Langsa dan Hasil evaluasi menunjukkan peningkatan nilai pemahaman peserta dari rata-rata 30 (pre-test) menjadi 80 (post-test). Sebanyak 70% peserta berhasil melakukan praktik secara mandiri dengan hasil fermentasi yang menunjukkan kualitas pupuk cair yang baik. Temuan ini menunjukkan bahwa pendekatan pelatihan yang berbasis kontekstual dan praktik langsung sangat efektif diterapkan di pendidikan nonformal untuk membangun keterampilan, kesadaran lingkungan, dan pemberdayaan warga belajar.

Abstract

Unsignalized intersections often become critical points of traffic problems due to increasing traffic volume that is not balanced with intersection capacity, resulting in delays, queues, and potential conflicts, especially during peak hours. This condition also occurs at the Unida Intersection (Universitas Iskandarmuda) in Banda Aceh, which serves traffic movements from campus areas, residential zones, and surrounding commercial activities. This study aims to analyze traffic flow characteristics and intersection performance using the Indonesian Highway Capacity Guidelines (PKJI 2023). The data used include traffic volume and geometric conditions of the intersection, which are then analyzed based on parameters such as capacity, degree of saturation, delay, queue probability, and level of service. The results show that the highest traffic volume occurs during the afternoon peak hour, reaching 1,089 pcu/hour, with a degree of saturation of 0.65. The average intersection delay is 12.989 seconds per vehicle, with a queue probability ranging from 17.47% to 36.09%. The level of service is classified as C, indicating that traffic flow remains stable but begins to be affected by congestion. Overall, the intersection still operates adequately however, further evaluation is needed to anticipate future increases in traffic volume.
