摘要：Indonesia is the country with the greatest potential for sago in the world.This research is intended to determine the carbon footprint of sago starch produced from a semi-mechanical process.The calculation was carried out using the LCA approach with the system boundary of cradle to gate.The process steps were carried out in a combination of manual work and diesel-driven engines.The inventory data on material, energy input flows and emissions were obtained from 3 samples of typical medium-scale semi-mechanical sago mills.It was found that the carbon footprint of the sago produced from semi-mechanical processes was 37.9±0.6 kgCO2eq per 1 ton of dried sago starch.Further analysis shows that 62% of the carbon footprint comes from the extraction stage and 38% from the transportation.It can be estimated that the amount of greenhouse gas emissions from the semi-mechanical sago starch production in Indonesia for 2018 reached around 2,617,639 kg CO2eq.
