Paper Title
Air Quality Assessment with Life Satisfaction Approach in Muara Enim Regency, South Sumatra Province in Indonesia

Abstract
The Sustainable Development Goal (SDG) for 2015 addresses the challenges faced by both developing and developed countries. In light of this, the objective of this paper is to estimate the assessment of air quality using a combination of the life satisfaction approach (L.S.), the fuzzy inference system (FIS), and the life cycle assessment (LCA). The research was conducted in Lawang Kidul District, Tanjung Enim Regency, South Sumatra Province, Indonesia, to evaluate the community's willingness to pay (WTP) in addressing air pollution. Face-to-face interviews were conducted using the contingent appraisal method (CVM) to measure the factors influencing WTP. The aim was to understand the community's capacity to improve the environmental profile through contributions from companies and the government. However, it should be noted that not all communities possess the same level of knowledge and resources to enhance environmental profiles. Furthermore, the analysis involves combining the fuzzy inference system (FIS) and life cycle assessment (LCA). The global warming potential (GWP) impact assessment for mining activities is 2.03 kg CO2 eq; diesel fuel is 0.937 kg CO2 eq; and electricity is 0.756 kg CO2 eq. The amount of particulate issued for mining activities is 0.015 kg PM2.5 equivalent, diesel fuel is 0.00106 kg PM2.5 equivalent, and electricity is 0.0139 kg PM2.5 equivalent.
