Lahan pertanian di Desa Akar-Akar didominasi oleh tanah kering dengan produktivitas rendah yang menjadi kendala utama bagi masyarakat petani. Di sisi lain, limbah tongkol jagung yang melimpah pasca panen belum dimanfaatkan secara optimal dan seringkali dianggap sebagai sampah. Kegiatan Kuliah Kerja Nyata (KKN) ini bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat petani di Desa Akar-Akar mengenai potensi pemanfaatan tongkol jagung sebagai biochar untuk perbaikan kualitas tanah. Metode kegiatan yang digunakan adalah pendekatan partisipatif melalui sosialisasi dan demonstrasi praktik. Tahap sosialisasi memberikan pemahaman teoritis mengenai manfaat biochar, sementara tahap demonstrasi mempraktikkan secara langsung proses pembuatan biochar menggunakan metode pirolisis sederhana dengan teknologi single drum kiln. Hasil dari kegiatan ini menunjukkan adanya peningkatan pemahaman dan kesadaran masyarakat secara signifikan mengenai manfaat biochar dalam memperbaiki sifat fisik, kimia, dan biologi tanah, serta kemampuan mereka untuk memproduksi biochar secara mandiri dari limbah pertanian lokal. Kesimpulan dari program ini adalah sosialisasi dan demonstrasi teknologi biochar tongkol jagung berhasil memperkenalkan sebuah solusi yang berbiaya rendah, ramah lingkungan, dan berkelanjutan untuk mengatasi masalah kesuburan tanah kering, sekaligus mengubah limbah menjadi sumber daya bernilai di Desa Akar-Akar.
