Research ArticleOpen accessPhrase in the titleOptimization of Biochar Quality from Palm and Cacao Waste through Variation of Pyrolysis Temperature and Duration as a Soil Amendment MaterialIwan Saputra, Sugeng Prijono et al.Palm and cacao waste are high-quality raw materials for producing quality biochar that enhances soil fertility, provided that the biochar production process takes into account various aspects of pyrolysis. The pyrolysis conditions, such as temperature and duration, significantly impact the quality of the biochar produced as a soil amendment. The type of raw material, pyrolysis temperature, duration, and other conditions … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 27 Jul 2024 · 5,558 accessesView PDFCite
