<![CDATA[Waste management and the underutilization of local resources remain challenges for rural communities and primary education in Indonesia, including in Nagari Tabek, Pariangan District, Tanah Datar Regency. This article synthesizes three community service activities conducted by students from the Faculty of Tarbiyah and Teacher Training at UIN Mahmud Yunus Batusangkar in 2026: guidance on processing banana stems and blossoms into Liquid Organic Fertilizer (POC); the conversion of used cooking oil into aromatherapy candles based on physics principles; and the BABAKU program (*Bambu Bakal Karya Kreatif* / Bamboo as a Basis for Creative Work), which involved training elementary school students to make bamboo piggy banks. All three activities employed a Participatory Action Research (PAR) approach, positioning community members and students as active agents of change. The synthesis reveals that abundant local materials—ranging from agricultural and household waste to natural resources—can be transformed into educational tools and useful products when supported by sustained guidance. These programs consistently fostered environmental awareness, practical skills, and a sense of ownership over the created products. The article recommends that this model of guidance based on local potential be further developed and replicated in future community service and educational initiatives.]]>
