Ansana River, Citric Acid, Carambola Wuluh, SSA


The river in the Angsana area has been polluted by lead metal caused by oil palm plantations and mining so that the river in the Angsana area is positive for containing high lead compounds. This is quite dangerous for health if you often carry out activities related to rivers such as bathing, washing or other activities. Reducing lead metal levels in river water can be done in various ways, one of which is by using natural ingredients, namely belimbing wuluh fruit which contains citric acid which is used as a metal binder or binder. To determine the potential of starfruit filtrate to reduce levels of lead (Pb) metal in river water in the Angsana Tanah Bumbu area, with time variations of 30 minutes, 60 minutes and 90 minutes. The type of research was Pre-Experimental design, then the research design was carried out in the form of a Post test only and group design and data analysis using One way Anova and then using a sampling technique with Purposive Sampling. The treatment used with a concentration of 75%, with a time of 30 minutes can reduce lead metal content by 24.45%, 60 minutes by 33.66%, and 90 minutes can reduce lead metal content by 37.29%. The results showed that belimbing wuluh filtrate had the potential to reduce lead metal content in river water in the Angsana area with an optimal time of 90 minutes. Carambola wuluh  filtrate has the potential to reduce lead levels in river water in the Angsana area with variations of 30 minutes, 60 minutes, 90 minutes. The optimal time for descent is 90 minutes.
