Abstract
Cocoa is the main plantation commodity which plays an important role in the Indonesian economy. In addition, cocoa is still the third largest source of non-oil and gas foreign exchange after rubber and palm oil. The area of cocoa plantations in Indonesia in 2015 reached 1. 722,315 ha. Cocoa bean production has continued to decline from 740,513 tons since 2012 to 656,817 tons in 2016. Cocoa is the main plantation crop in several regions in Indonesia, including West Sulawesi. However, cocoa farmers have various problems. One of them is low productivity. The average cocoa productivity is only 650 kg / ha / year. This productivity is still carried by the optimum cocoa productivity. One of the causes of low cocoa productivity is that cocoa plants are planted on inappropriate land. One of the land requirements that must be suitable is the physical and chemical of the soil. This research uses quantitative methods with a deductive approach This research was conducted in West Sulawesi Province in January-August 2020. The results showed that There is a correlation between Same of Basic Cations and cocoa productivity. The bases saturation (Ca, Mg and K) does not have a significant effect on the productivity of cocoa plants in the high productivity category. There is no correlation between pH H20 and cocoa productivity. pH H20 has a positive correlation with C-Organic, salinity, base saturation and the bases saturation.
