The community and industrial activities such as mining, agriculture, plantations, and natural activities that directly or indirectly enter the waters of the Musi River can result in river pollution, such as the inclusion of waste, including ammonia. The existence of ammonia that exceeds the specified quality standard value can disrupt the ecosystem in the waters and the living creatures around …
Mud crabs are an important component of fisheries in coastal areas. Crab ranks third after shrimp and lobster because of the delicacy of seafood and also the fishery value it supports. The world's crab fisheries are thriving and there is a wide scope for crab meat not only for the delicacy of the meat but also for its nutritional richness. Antioxidants are included in certain substances that ca…
Nutrients are very important for the growth of an organism in the water. The entry of waste or waste products can reduce the quality of waters leading to an increase in nutrient concentrations in the water column. This study aims to determine the condition of nutrients in water and sediment and analyze the condition of Payung Island Waters. Sampling was carried out in September 2022 at 5 resear…
