This study examines the introduction of a combination of cocoa husk biochar which has been a cocoa plantation waste combined with fermented cocoa leaf waste. This study was conducted in West Sulawesi. This study used a randomized block design using a factorial model where the first factor was the administration of cocoa husk biochar with 3 levels, namely without administration (B0), 6 kg plant biochar-1 (B1), 12 kg plant biochar-1(B2) while the second factor was application of fermented cocoa leaf waste (K) which consists of 3 levels, namely without giving cocoa leaf waste (K0), giving 6 kg plant-1 (K1), biochar 12 kg plant-1 (K2). The nine treatment combinations were repeated three times to obtain 27 plant samples. The analysed soil characteristics are calcium (Ca), magnesium (Mg) and potassium (K) showed that the combination of cocoa rind Biochar and fermented cocoa leaf waste had an effect on increasing calcium (Ca) by 9.23. Magnesium 1.66 and for the element Potassium had no significant effect on the interaction of the combination of cocoa husk biochar and fermented cocoa leaf waste, but gave a very significant effect on the administration of biochar 12 kg plants-1.
