Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ′) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

Toxicity is the ability of a substance or chemical which, when exposed for a certain period, can cause damage to organisms. Factors that influence toxicity are composition, type, duration and frequency of exposure, recipient biota species and environmental characteristics. The results of this test describe the values LC50-96 hours or LC50-48 hours. The LC50 value is the concentration at which the extract solution can cause population death of up to 50%. This study aims to determine the concentration of acute toxicity of liquid palm oil waste on tilapia fish seeds and its effect on the organoleptic properties of tilapia. This research was carried out from May to July 2023 at the Aquatic Resources Management Laboratory, Faculty of Agriculture, Tanjungpura University. The method used is a static method in acute toxicity tests to determine the death of 50% of the number of test organisms. This research was carried out in 4 stages, namely preparation, preliminary test, toxicity test and treatment test. The toxicity test data was then analyzed using probit analysis. The LC50-96 hours value of palm oil liquid waste for the tilapia fish seed biota test is 4.88 mg/l. The LC50-96 hours value obtained from probit analysis is used to determine the TUa (Toxicity Unit Area) value by converting the LC50-96 hours value. The TUa value obtained was 20,49 indicating that the acute toxicity level of liquid palm oil waste causes acute toxicity.
