Sekolah Tersenyum — Cooking Oil to Biodiesel
Creator: Rumah Sosial Kutub (LAZ) · DKI Jakarta (+ Tegal, Yogyakarta)
RSIK's flagship “Sekolah Tersenyum” collects used cooking oil (minyak jelantah) at schools, converts it to biodiesel, and channels the proceeds into orphan education — a circular loop (SDG 12 → 7 → 4). Oil collected and processed is the retroactive output; verified liters, biodiesel sold, and funds reaching students are the prospective outcome. “Kutub” = Komunitas Tahajud Berantai; RSIK is a city-level LAZ (Jakarta Selatan, SK 205/2023); 211,375 cumulative beneficiaries (2026). Figures illustrative.
