TAHAPAN KOLABORASI PESANTREN DAN MASYARAKAT DALAM MEWUJUDKAN LINGKUNGAN BERKELANJUTAN: STUDI KASUS GERAKAN KRAPYAK PEDULI SAMPAH PONDOK PESANTREN ALI MAKSUM YOGYAKARTANIM.: 22102030025Ratna PuspitasariauthorThe waste management problem in the Special Region of Yogyakarta highlights the need for environmental management involving multiple stakeholders. Pondok Pesantren Ali Maksum Krapyak initiated the Krapyak Peduli Sampah (Krapyak Waste Care Movement) as a collaborative effort between the Islamic boarding school and the surrounding community to promote environmental sustainability. This study aims to describe the stages of collaboration between the pesantren and the community in the Krapyak Peduli Sampah Movement and to analyze its impact on environmental sustainability. This research employed a qualitative method with a case study approach. Data were collected through observation, interviews, and documentation, and were analyzed using the Miles, Huberman, and Saldaña interactive model, which consists of data condensation, data display, and conclusion drawing. The findings indicate that the collaboration followed Barbara Gray’s three stages of collaboration: problem setting, direction setting, and implementation. The collaboration was carried out through waste sorting, collection, processing, and environmental education activities involving the pesantren, students, and the local community. The impacts of the collaboration were evident in ecological improvements through reduced waste volume and a cleaner environment, social improvements through increased awareness, concern, and community participation, and economic benefits through the utilization of recyclable waste and reduced waste management costs. However, community participation in the planning and decision-making processes still needs to be strengthened. This study concludes that community-based collaboration between the pesantren and the local community contributes to more participatory and sustainable environmental management.307.14 Pengembangan Masyarakat2026-06-17UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS DAKWAH DAN KOMUNIKASIThesis
