The increasing demand for resource efficiency in Indonesia drives the exploration of sustainable alternative resources from agricultural waste. One underexploited potential is cocoa pod husk waste, which can be processed into biochar as a soil amendment and an ecological resource. This research aimed to analyze the availability of cocoa pod husk waste as biochar feedstock, evaluate the effectiveness of biochar in improving soil pH, and assess the economic and environmental feasibility using the Cost-Benefit Analysis (CBA) approach in Sungai Langka Village, Pesawaran Regency. The study employed mixed methods with quantitative and qualitative analysis. Primary data were collected through field observation and interviews with farmers, while secondary data were obtained from literature studies and relevant documents. The economic feasibility was assessed using three main indicators: Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit Cost Ratio (BCR). The analysis revealed that cocoa pod husk availability is highly adequate, with an annual generation of 4,545 tons. Furthermore, the biochar product was scientifically proven effective in neutralizing soil pH from 5,8 to a neutral pH 7,3. The Cost-Benefit Analysis concluded that the biochar production investment is highly viable for implementation. The analysis indicators yielded a Net Present Value (NPV) of Rp188.925.276 an Internal Rate of Return (IRR) of 10,30%, and a Benefit Cost Ratio (BCR) of 1,23.

Upaya peningkatan kualitas lingkungan dan ekonomi masyarakat di Indonesia mendorong eksplorasi sumber daya terbarukan dari limbah pertanian. Salah satu potensi yang belum dimanfaatkan secara optimal adalah limbah kulit kakao, yang dapat diolah menjadi biochar sebagai pembenah tanah dan sumber daya ekologis. Penelitian ini bertujuan untuk menganalisis ketersediaan limbah kulit kakao sebagai bahan baku biochar, menganalisis efektivitas biochar terhadap perbaikan pH tanah, dan menganalisis kelayakan ekonomi serta lingkungan dengan pendekatan Cost-Benefit Analysis (CBA) di Desa Sungai Langka, Kabupaten Pesawaran. Metode penelitian menggunakan mixed methods dengan pendekatan kuantitatif dan kualitatif. Data primer dikumpulkan melalui observasi lapangan dan wawancara dengan petani, sementara data sekunder diperoleh dari studi literatur dan dokumen terkait. Analisis kelayakan ekonomi dilakukan dengan tiga indikator utama, yaitu Net Present Value (NPV), Internal Rate of Return (IRR), dan Benefit Cost Ratio (BCR). Dari analisis yang dilakukan, ketersediaan kulit kakao sangat memadai dengan timbulan 4.545 ton per tahun, dan secara ilmiah biochar terbukti efektif menaikkan pH tanah dari 5,8 ke pH netral 7,3. Dengan metode Cost-Benefit Analysis diketahui bahwa investasi produksi biochar kulit kakao layak untuk diimplementasikan. Hasil analisis menunjukan hasil Net Present Value (NPV) sebesar Rp188.925.276, Internal Rate of Return (IRR) sebesar 10,30% serta Benefit Cost Ratio (BCR) bernilai 1,23.
