Pengaruh Pemberian Em4 Dalam Biofilter Untuk Menurunkan Kadar Total Suspended Solid (Tss) Dan Amonia (Nh3) Pada Pengolahan Limbah Cair Rumah Makan
Restaurant liquid waste may pollute aquatic environment as it has high TSS and NH3 content. It should be processed before being flown to environment. This study aims to understand the effectiveness of EM4 addition in reducing TSS and ammonia content in the restaurant liquid waste. This research was carried out in April 2019 at the Naga Sakti street. A Completely Randomized Design (CRD) was applied with 3 treatments P0 (without EM4), P1 (7,5 ml EM4), P2 (10 ml EM4), P3 (12,5 ml EM4) and 3 replications. The restaurant liquid waste was kept in the biofilter tank for 6 days (3 days in the anaerob and 3 days in the aerob tanks) and then the TSS and ammonia were analyzed. The best result was obtained in the P2 (10 ml/L EM4). In that treatment the TSS decreased from 196 mg/L into 63 mg/L and NH3 from 9.08 mg/L into 4.07 mg/L. The treated liquid waste was then use for rearing Oreochromis niloticus sized 3-5 cm for 96 hours. The survival rate of the fish was 86%. Data obtained shown that the processed restaurant liquid waste can be used to rear Oreochromis niloticus.
