Abstract

Water is an essential need for living things on earth. The increasing
population causes the availability of clean water to decrease. This is caused by the high level of water pollution by waste, including domestic waste such as detergent (LAS). Various methods can be used to overcome water pollution, including phytoremediation techniques. One of the aquatic plants as a phytoremediation
agent is the Coix lacryma-jobi plant. This study aims to examine the effectiveness of the ability of the Coix lacryma-jobi plant to absorb LAS. The method used is an experimental method using a Completely Randomized Design (CRD) with 5 treatments and 4 replications (plant control; LAS 4 mg/L; LAS 8 mg/L; LAS 16
mg/L; LAS 32 mg/L; LAS 64 mg/L with a detention time of 15 days. The results showed that hanjali plants were effective in absorbing LAS with the highest removal capacity of 94% in water contaminated with LAS 4 mg/L. The temperature and pH values fluctuated and the TDS value increased along with the increase in LAS concentration. Therefore, this plant can be said to be effective in absorbing LAS pollutants.
