Abstract

The accumulation of organic waste, such as pineapple peels, requires innovative and sustainable management approaches. Biochar, a carbon-rich material derived from pyrolysis, has been identified as a promising bulking agent to improve composting efficiency. This study investigated the effect of nipah biochar produced at different pyrolysis temperatures (350°C and 450°C) on pineapple peel composting. The characteristics of the biochar were analyzed using XRD and SEM to determine its mineral composition and pore structure, while the composting efficiency was evaluated by measuring pH, moisture retention, and nutrient content. The results showed that the biochar produced at 450°C had a more stable mineral composition—such as graphite, gamma alumina, and quartz—and higher porosity compared to the biochar at 350°C. During the composting process, the 450°C biochar significantly improved pH regulation to the optimal range of 6-7, moisture retention by 50-60%, and compost quality. The decomposition process was also faster, producing compost with higher nitrogen content and C/N ratio compared to the control without biochar. These findings highlight the potential of nipah biochar at high pyrolysis temperatures as an effective bulking agent for sustainable organic waste management.

Abstract

Permasalahan sampah masih menjadi isu krusial di Indonesia, termasuk di Kota Jambi yang menghasilkan timbulan sampah sebesar 447,7 ton per hari dengan dominasi sampah makanan dan plastik. Tempat Pengolahan Sampah Reduce, Reuse, Recycle (TPS 3R) Sinar Kenali merupakan salah satu TPS 3R yang terdapat di Kota Jambi untuk mendukung prinsip pengelolaan sampah berkelanjutan. Kegiatan ini dilaksanakan oleh tim pengabdian Universitas Jambi dengan tujuan meningkatkan pengetahuan, kesadaran, dan partisipasi masyarakat dalam pengelolaan sampah. Metode kegiatan meliputi penyuluhan, pelatihan, promosi media cetak dan digital, serta keterlibatan langsung masyarakat. Hasil evaluasi menunjukkan adanya peningkatan signifikan pengetahuan masyarakat terkait pemilahan sampah, ditunjukkan oleh kenaikan pemahaman perbedaan sampah organik dan anorganik hingga 100% dan peningkatan kebiasaan memilah sampah dari 23% menjadi 57%. Kepemilikan tempat sampah terpilah di rumah meningkat dari 12% menjadi 35%, sedangkan ketersediaan fasilitas pemilahan di lingkungan naik dari 58% menjadi 74%. Namun, pemahaman konsep bank sampah mengalami penurunan, yang mengindikasikan perlunya peningkatan pemahaman secara fungsional. Secara keseluruhan, kegiatan sosialisasi dan pemasaran TPS 3R Sinar Kenali terbukti efektif meningkatkan pengetahuan dan kesadaran masyarakat, meskipun masih diperlukan dukungan infrastruktur, kolaborasi lintas sektor, serta edukasi berkelanjutan untuk memperkuat budaya pengelolaan sampah berkelanjutan.
