Degradation of carbon stock (C) in calculation analysis of greenhouse gas emissions in cocoa plantations in South Sulawesi

Abstract

Cocoa as one of the most developed plantation commodities in Indonesia has a strategic position in efforts to increase carbon absorption to reduce the rate of global warming. As a woody plant, cocoa can absorb CO2 from the air and store it in the form of carbon (C) in its body (biomass). The absorption process of CO2 also affects the rate of photosynthesis in plants as the main ingredient in the breakdown of carbon in the plant body, especially cocoa. This research was conducted in Gantarangkeke District, Bantaeng Regency, South Sulawesi. Sampling was carried out by purposive sampling method on the basis of consideration of the type, density and cropping system applied. The estimation of biomass used a non-destructive method by measuring the diameter at breast height (DBH 1.3 m) and the height of the cocoa. Carbon storage in cocoa is differentiated by several plant ages, namely 5 years and 10 years. The results showed that the carbon stock in Bantaeng Regency was 27.05 tons/Ha.
