Abstract
Indonesia faces environmental challenges due to increased exploitation of natural resources and emissions generated by industrial production processes. This study aims to design an environmental impact mitigation strategy using the Life Cycle Assessment (LCA) method in one of the furniture industries, namely UD Putra Bali. This study includes a life cycle analysis of wooden doors which includes the stages of data collection, Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), and Life Cycle Interpretation, Fishbone diagram, repair with cleaner production, and saving matrix. The results of the study show that the life cycle of wooden door products has an environmental impact of 13.1 kPt. The stage that has the greatest impact is finishing in the human toxicity water category of 11.3 kPt and shipping of finished products in the global warming category of 0.0539 kPt. The cause is sought using a fishbone diagram so that repairs can be made. Recommendations for repairs proposed are based on cleaner production. Improvements in the finishing process include replacing the paint material from thinner solvent paint to water solvent paint. Improvements in the transportation process include companies can use a cooperation contract agreement with the shipping party containing the requirements for using a minimum Euro 4 vehicle and for the shipping route, using a route that has been determined with the saving matrix nearest insert.

Abstract
Life cycle assessment (LCA) is a valuable tool not only for analyzing the environmental impact of a product but also for assisting in early-stage product development before incurring scaling-up costs. When validating a new process or project, it may be constrained to align with existing regulations or standards. Therefore, combining LCA with other applicable standards is essential to demonstrate the project's feasibility. In this regard, the water quality index (WQI) and Water Exploitation Index (WEI) provide additional information that reflects the overall water quality at a specific location and time. The objective of this study is to utilize the LCA framework in conjunction with the Malaysia WQI and WEI to protect the water quantity and water quality of the river. A negative change in the WQI score indicates that the current effluent from the process is degrading the river's classification, rendering it undesirable and necessitating a reduction in concentration. The findings demonstrate that the method for determining effluent requirements for a water treatment system is straightforward and replicable. Such an approach could be employed, for example, in an environmental impact analysis of a project to verify its viability.
