Batik industry liquid waste in Ulu Gedong Village, DanauTeluk District, Jambi City,must be managed so it doesn’t pollute the surrounding environment. Many factors influence the need for properly treated batik liquid waste. Thus, it is necessary to know what factors cause pollution and the right strategy for managing Batik industry wastewater in Ulu Gedong Village, DanauTeluk District, Jambi City. The aims of this study were (1) to analyze aspects that influence the liquid waste management strategy for Batik industries in Ulu Gedong Vil-lage, DanauTeluk District, Jambi City, (2) to determine the appropriate strategy for managing Batik industry wastewater in Ulu Gedong Village, DanauTeluk District, Jambi City.The number of respondents in this study consisted of 20 people using the Analytic Network Process method and using the “Super Decision” software. The results showed that the most influential aspects in the management of Batik industry liquid waste in Ulu Gedong Village, DanauTeluk District, namely Cultural aspects (0.92), Economic (0.80), Social (0.45), Manage-ment (0.42), and Technical (0.41). The main priority in the Batik industry liquid waste management strategy is providing convenience and incentives to businesses participating in wastewater management, such as granting business licenses and tax breaks. So it is hoped that the role of the Jambi City government can strive to provide convenience and incentive assistance to batik entrepreneurs who have or want to build batik Wastewater Man-agement Installation facilities.

The landfill is a place used for landfill that can have a negative impact on the environment such as, causing greenhouse gas emissions, soil contamination, and groundwater pollution. Landfill gas content of CH4, CO2 and non-methane organic compounds (NMOC) is the cause of the greenhouse effect and Global warming potential (GWP). The concentration of CH4 in landfill gas is relatively low, but CH4 causes a greenhouse effect 21 times greater than CO2 . The research was conducted at the Talang Gulo landfill in Jambi City. The purpose of this study is to measure and analyze the production and amount of CH4 gas concentration emitted into the atmosphere and assess methane gas emissions as an energy source. The Application to estimate gas using models was with LandGEM-v302 soft-ware. The results of LandGEM-v302 simulation of landfill gas show a peak in 2023 of 3,194×104 Mg·year-1 for total landfill gas, methane emissions A6 (8,530×103 Mg·year-1), carbon dioxide (2,341×104 Mg year-1) and NMOC (3,667×102 Mg·year-1). The potential of methane gas as a source of fuel energy is 11,403,693.84 kg·year-1 and electrical energy is 182,862.08 kWh.
