Pertumbuhan Bakteri Heterotrofik Pada Perairan Laut Tercemar Detergen Surf

---

Heterotrophic bacteria are decomposing bacteria that have an important role in maintaining the continuity of the life cycle of biota in the sea and as a standard of fertility in the waters. Heterotrophic bacteria obtain sources of food, oxygen and energy derived from the results of the decomposition process of the rest of other organisms, waste, or substances contained in the bodies of other organisms. This study found out the effect of detergent addition on the growth of heterotrophic bacteria in water. Knowing the ratio of the ability of bacteria to survive the length of exposure differs between 5 and 10 (Days). This research was conducted from April to May 2018 using the experimental method. The results showed that the bacterial population in each treatment decreased with increasing concentration of detergent. The results showed that the highest number of heterotrophic bacteria was found at a concentration of 0.60% at station 1 exposure on the 10th day at 6.60 x 107 (CFU / ml) and 0.90% at the station on the 10th day of the day exposure the 10th was 6.72 x 107 (CFU / ml) and the lowest was found at a concentration of 0.90% on day 5 exposure at station 1 at 3.83 x 107 (CFU / ml). The value of the correlation coefficient (r) obtained is 0.177. Significant treatment of detergent concentration is different, which is equal to 0.00 < (0.550) and duration of exposure which is equal to 0.00
