Biochar is produced from the pyrolysis of organic matter (waste and biomass of agriculture) e.g young coconut waste (YCW). However, there is little information describing methods for producing biochar as an ameliorant for agriculture. Therefore, research is needed to determine the biochar characteristics of the Kon-Tiki, Drum, and Soil-Pit methods. This study was conducted using a Completely Randomized Design with three replications. The results of biochar production with methods significant on temperature (682°C), moisture (81.27 %), dry weight (2.09 kg) and yield ratio (20.87%) of biochar, and characteristics of biochar from YCW on pH (10.82 unit), liming potential (5.50% CaCO3), proximate analysis (moisture of 38.80%; volatile matter of 62.73%; ash of 19.50% and fixed carbon of 43.22%), CEC (457.13 mmol kg −1 ), cation base (K of 356.14 and Na-exch of 131.28 mmol kg −1 ), Cárgame (0.35 g kg −1 ), and C Organic (14.27 g kg −1 ), with the recommended method of YCW biochar production using the Kon-Tiki method.
