ABSTRACT
The intensive use of artificial feed in Nile tilapia (Oreochromis niloticus) aquaculture contributes to the accumulation of dissolved organic waste, potentially degrading aquatic environmental quality. This study aimed to evaluate the impacts of dissolved organic waste derived from artificial feed on water quality in culture ponds managed by Pokdakan Sugih Makmur, Mentaos Subdistrict, South Kalimantan, Indonesia. Water quality assessment was conducted using physical, chemical, and biological parameters, including total organic matter, ammonia, total coliform, plankton, and macrozoobenthos. The results indicated that total organic matter exceeded permissible standards at all monitoring stations, while ammonia concentrations at the outlet station surpassed the threshold of 0.5 mg/L. Elevated total coliform levels were recorded at several stations, indicating significant microbiological contamination. Biological indicators showed low to moderate diversity with dominance of tolerant species, reflecting ecological stress conditions. Based on these findings, the implementation of a Strength–Threat (ST) management strategy is recommended, emphasizing the use of bioindicators as an early warning system, enhancement of farmers' capacity, development of environmentally friendly technologies, and strengthening multi-stakeholder collaboration. This study highlights the importance of integrated environmental management to ensure sustainable tilapia aquaculture practices.
