Abstract
Telaga Rambit in Purwodadi Village, Sidayu District, Gresik Regency, is used as a water source by the local community, but is currently polluted by domestic wastewater. Tamarind seeds (Tamarindus indica) and papaya seeds (Carica papaya) were selected as natural coagulants due to their high protein content that can function as natural polyelectrolytes. Water treatment is enhanced by the adsorption process through the utilization of chicken eggshells as a green adsorbent. This study aims to analyze the effect of pH and coagulant dose on the coagulation-flocculation process, analyze the effect of sampling time and adsorbent mass on the adsorption process, and analyze the effectiveness of the combination of green coagulant and eggshell green adsorbent in reducing BOD, COD, and TSS. The results showed that papaya seeds were most effective in reducing BOD (22.5%), COD (27.4%), and TSS (51.22%) at pH 7 and a dose of 40 ml. The adsorption process was carried out in a continuous adsorption column. The results obtained from the combination of papaya seeds and eggshells with a mass of 1400 grams and a sampling time of 50 minutes were able to produce a decrease in BOD (59%), COD (62%), and TSS (60%). Overall, the combination of papaya seed green coagulant and eggshell green adsorbent in a series of coagulation-flocculation and adsorption combination treatment is able to provide the highest effectiveness with a total decrease in BOD by 68%, COD by 72%, and TSS by 80%. Keywords: Adsorption, Eggshell, Green Coagulant, Coagulation-Flocculation
