Abstract

Indonesia merupakan negara agraris yang memiliki potensi besar dalam sektor pertanian, khususnya pada komoditas padi. Pada tahun 2024, luas lahan sawah di Indonesia tercatat mencapai 8.186.469,65 hektare, meningkat sekitar 1,16% dibandingkan tahun sebelumnya. Kabupaten Tuban termasuk dalam lima besar wilayah dengan produksi padi tertinggi di Provinsi Jawa Timur, dengan total produksi sebesar 282.747 ton dan luas lahan sawah lebih dari 30.000 hektare. Penelitian ini bertujuan untuk mengkaji potensi pemanfaatan limbah sekam padi varietas Inpari 32 sebagai biochar melalui proses pirolisis. Biochar yang dihasilkan dianalisis menggunakan metode X-Ray Fluorescence (XRF), uji proksimat, dan uji nilai kalor. Hasil penelitian menunjukkan bahwa biochar dari Kecamatan Jenu memiliki nilai kalor tertinggi, yaitu sebesar 4.847 Kkal/Kg, sedangkan nilai karbon tetap tertinggi ditemukan pada sampel dari Kecamatan Plumpang, yaitu sebesar 50,94%. Kandungan silika (SiO₂) mendominasi biochar di seluruh lokasi, dengan nilai tertinggi sebesar 78,5% di Kecamatan Jenu. Tingginya kandungan silika ini menunjukkan bahwa biochar sekam padi berpotensi dimanfaatkan sebagai pembenah tanah dan sumber energi alternatif berbasis padatan. Meskipun nilai kalor belum memenuhi standar minimum SNI untuk briket arang (5.000 Kkal/Kg), biochar tetap berpotensi digunakan sebagai bahan bakar tambahan (co-fuel) atau bahan bakar padat terbarukan (solid biofuel). Penelitian ini memberikan kontribusi dalam pengembangan energi terbarukan berbasis limbah pertanian, serta mendukung kebijakan pertanian berkelanjutan di tingkat lokal.

Indonesia is an agricultural country with substantial potential in the farming sector, particularly in rice production. In 2024, the total rice field area in Indonesia reached 8,186,469.65 hectares, marking an increase of approximately 1.16% compared to the previous year. Tuban Regency ranks among the top five rice-producing regions in East Java Province, with a total production of 282,747 tons and more than 30,000 hectares of rice fields. This study aims to assess the potential utilization of rice husk waste from Inpari 32 rice variety as biochar through a pyrolysis process. The resulting biochar was analyzed using X-Ray Fluorescence (XRF), proximate analysis, and calorific value testing (bomb calorimeter).The findings indicate that the biochar from Jenu District had the highest calorific value of 4,847 Kcal/Kg, while the highest fixed carbon content was recorded in Plumpang District at 50.94%. Silica (SiO₂) content dominated biochar across all locations, with the highest concentration (78.5%) also found in Jenu District. The high silica content demonstrates that the rice husk biochar has potential not only as a soil amendment but also as a solid-based bioenergy source. Although the calorific value does not meet the national standard (SNI) of 5,000 Kcal/Kg for charcoal briquettes, the biochar still shows promise for use as a co-fuel or solid biofuel. This research contributes to the development of renewable energy from agricultural waste and supports sustainable agricultural policies at the local level.
