      Abstract
      Limbah organik berkadar lignoselulosa tinggi berpotensi diolah melalui proses pirolisis menjadi biochar yang dapat dimanfaatkan sebagai pembenah tanah pada tanah pertanian yang terdegradasi. Penelitian ini bertujuan menganalisis potensi limbah lignoselulosa sebagai biochar, mengevaluasi pengaruhnya terhadap perbaikan kualitas tanah pertanian yang terdegradasi, serta menilai efektivitasnya dalam mendukung produktivitas tanaman. Metode yang digunakan adalah pirolisis pada suhu di atas 300 °C selama kurang lebih 1 jam, dengan uji efektivitas pada media tanam menggunakan rancangan acak lengkap faktorial dengan dua faktor yaitu pemberian biochar awal dan tambahan pada tanaman sawi hijau (Brassica rapa caisin). Hasil penelitian menunjukkan bahwa aplikasi biochar secara signifikan mampu memperbaiki sifat kimia tanah, yaitu meningkatkan pH tanah dari 5,4 menjadi 6,6, kadar C organik hingga 6,0%, kadar N total menjadi 0,6%, dan rasio C/N tanah hingga 10,3. Perlakuan A3T2 mencatatkan pertumbuhan tinggi tertinggi sebesar 9,2 cm, sedangkan perlakuan A3T3 mencatatkan penambahan berat basah total terbesar sebesar 10,0 g. Simpulan penelitian ini adalah penambahan biochar dari limbah organik berkadar lignoselulosa tinggi berpotensi sebagai pembenah tanah.
       
      High lignocellulosic organic waste has the potential to be processed through pyrolysis into biochar, which can be utilized as a soil amendment in degraded agricultural land. This study aims to analyze the potential of lignocellulosic waste as biochar, evaluate its effect on improving the quality of degraded agricultural soil, and assess its effectiveness in supporting crop productivity. The method used was pyrolysis at temperatures above 300 °C for approximately 1 hour, with an effectiveness test on the planting medium using a factorial completely randomized design with two factors, namely the initial and additional application of biochar on mustard greens (Brassica rapa caisin). The results showed that biochar application was able to significantly improve soil chemical properties, specifically increasing soil pH from 5.4 to 6.6, organic C content to 6.0%, total N content to 0.6%, and the soil C/N ratio up to 10.3. The A3T2 treatment recorded the highest height growth of 9.2 cm, while the A3T3 treatment recorded the largest total fresh weight addition of 10.0 g. In conclusion, the addition of biochar from high lignocellulosic organic waste shows potential as a soil amendment.
