Abstract

Embung Tirtoagung is an artificial aquatic ecosystem as a supplier of agricultural land during the dry season and as a fishery facility in Sleman Regency. This study aims to determine the water quality in Tirtoagung Embung based on the diversity index and saprobic index. This research is an exploratory descriptive research by way of observation. The research was conducted in February – April 2021 during the rainy season. The sampling locations were at 5 stations selected by random sampling. The results of the study showed that the water quality in Tirtoagung Embung is included in the lightly polluted category. It is known from the calculation of the diversity index that is 2,391 so that the situation is in the moderate category and the Tirtoagung reservoir is in a lightly polluted condition. Then seen from the calculation of the saprobic index, which is 0.71 - 1.00 so that the condition of the waters of the Tirtoagung reservoir is in the - mesosaprobic phase with light pollution levels and few organic and inorganic compounds. In addition, the water quality of the Tirtoagung reservoir based on physical and chemical parameters is still feasible for the survival of phytoplankton.

Abstract

This research aims to determine: (1) The structure of the zooplankton community in Telaga Namberan, Gunungkidul Regency, (2) The chemical and physical conditions of the waters in Telaga Namberan, Gunungkidul Regency, (3) The relationship between the structure of the zooplankton community and water quality in Telaga Namberan, Regency Gunungkidul. This research is exploratory research with observational research methods. Sampling was carried out at 6 stations 2 times with 3 repetitions. The research results show that the abundance value is 16216.56 - 877388.54 ind/L, meaning it is classified as water with high nutrient levels. The average dominance value of 0.495 means that the community structure is in a stable condition. The average diversity value is 1.098, meaning that the number of individuals of each species is relatively evenly distributed with fairly stable water conditions. The average evenness value is 0.501, meaning it has even species and the community is relatively stable. Frequency of attendanceCyclopssp., Nauplius sp., Notholca sp 1 always appear at all stations because they can adapt and fit to live in the environment.
