Abstract
Low public awareness regarding the prohibition of waste disposal into water bodies in Lampenai Village has led to a long-term accumulation of riverine debris that flows into the sea, causing persistent ecosystem degradation. This study evaluates the effectiveness of physical intervention through the installation of trash barriers at strategic locations as a pollution mitigation strategy. A quantitative observational method was employed, involving direct on-site monitoring and variable measurement without experimental manipulation. The research analyzes the correlation between the trash barrier's capture efficiency and ecological conditions, integrated with average daily waste generation data based on population statistics. The results demonstrate a significant waste capture performance across four monitoring stations: Station 1 (123.2%), Station 2 (111.4%), Station 3 (108.1%), and Station 4 (103.8%). These percentages, exceeding 100%, indicate that the actual captured waste load surpasses the estimated daily generation per capita, suggesting the presence of existing accumulated debris within the river flow.
