Life Cycle Assessment of the Solok Rice Production System in the Gunung Talang District, Solok Regency, West Sumatra

Solok rice is an important agricultural commodity that contributes significantly to the economic prosperity of West Sumatra region. As indigenous knowledge from Sumatra, development and preservation can stimulate a nationwide increase in production. The cumulative effects entire sequence activities comprising production will impact environmental quality due increased output. Therefore, Life Cycle Assessment (LCA)-based assessment necessary. analysis results indicate total greenhouse gas emissions equal 1.94 kg CO2eq per kilogram rice. subsequent potential include acidification at rate 0.06 kilograms SO2-equivalent eutrophication PO43-equivalent calculation net energy yielded Net Energy Value (NEV) 18.36 GJ Ratio (NER) greater than 1. To mitigate emission values land environment, current system improvement emphasizes fertilizer consumption, increasing use organic materials, instituting waste recycling.
