The ABC metal SME produces some wastes, such as liquid waste, solid waste, and smoke. The problem is hazardous waste dumped directly into the environment without any waste treatments, which had a terrible impact on the environment around its SME. Therefore, this research is proposed to improve the production process of metal that can reduce environmental impacts. The Life Cycle Assessment (LCA) method is developed to identify all the processes that impact the environment and calculate the energy used. The values of environmental impact are calculated using Simapro 9.0 Software. In addition, the Analytical Hierarchy Process (AHP) method is employed to determine the best alternative fuel according to four criteria: temperature, price, emission, and fuel consumption. The results show the process that has the most significant environmental impact is the metal smelting process. It is caused by the source fuel in this process was used oil. The usage of used oil can be the source of air pollution that causing health problems in the respiratory tract, such as bronchitis and asthma. However, some alternative fuel was proposed; however, the fuel gas is the best alternative, according to expert opinions. For managerial insight, this research can be a suggestion for SME to choose the best fuel in the production process that considering economic and environmental aspects.
