Opis:: The use of phytoplankton as an indicator of water pollution is a promising tool for assessment of water quality. The purpose of this study was to determine whether diversity indices, including the species richness and diversity of phyto-plankton, could be used for reliable assessment of water quality in the Wadaslintang Reservoir in Indonesia. Surveys were conducted monthly at eight sites, from July 2019 to October 2019. Phytoplankton was collected during the day at 10:00 until approximately 15:00 in the euphotic zone. The parameters investigated were species richness and the abundance of phytoplankton, as well as water quality parameters listed in Government Regulation Number 82 of 2001. The level of pollution was represented biologically by the Shannon–Wiener diversity index and physicochemically by the STORET (storage and retrieval of water quality data) index. Moreover, the two indices were compared to determine whether a particular diversity index was more effective for assessment of this reservoir. The results showed that during the dry season, 22 taxa of phytoplankton were present, belonging to Cyanophyta, Chlorophyta, Chrysophyta, and Euglenophyta. During the wet season, 29 taxa were found, belonging to Cyanophyta, Chlorophyta, and Chrysophyta. Based on the Shannon-Wiener index and STORET index, water quality was better during the wet season than during the dry season. The results of water quality assessment using both indices were consistent, but the diversity index was a more sensitive indicator of pollution levels. Therefore, the Shannon–Wiener index is a useful tool for assessment of water quality in the Wadaslintang Reservoir.

Opis:: The water of Lake Rawa Pening is used as a source of drinking water. Indonesian Government Regulation Number 82 of 2001 on Management of Water Quality and Water Pollution Control stated that the water quality of Lake Rawa Pening should meet the quality standard of first grade and be categorized as no polluted water. The purpose of this research was to assess the water quality based on Indonesian regulation and to assess water quality based on international regulations. The quality of water was assessed using a survey method in 7 sites of the Lake Rawa Pening 3 times for 3 months. Parameters measured were all the water quality parameters required in accordance with Government Regulation No. 82 of 2001. The results indicated that there were 13 values that exceeded the water quality standard of first grade. These exceeded parameters were total suspended solids (TSS), biological oxygen demand (BOD), chemical oxygen demand (COD), orthophosphate (PO₄), NO₃, As, Se, Cd, Mn, Cu, Pb, H₂S, faecal coliform, and total coliform. Water quality status of Lake Rawa Pening was categorized as heavily polluted. The water quality of Lake Rawa Pening should be improved by reducing the pollutants entering the lake by restriction of human activities causing lake pollution.
Woda jeziora Rawa Pening jest wykorzystywana jako źródło wody pitnej. Rozporządzenie rządu Indonezji nr 82 z 2001 r. o zarządzaniu jakością wody i kontroli zanieczyszczeń stwierdza, że woda jeziora powinna spełniać standardy jakości wody pierwszego stopnia i być klasyfikowana jako woda pozbawiona zanieczyszczeń. Celem badań była ocena jakości wody według indonezyjskich i międzynarodowych norm. Jakość wody oceniano w 7 stanowiskach jeziora trzykrotnie w ciągu 3 miesięcy. Mierzone parametry odpowiadały zawartym w rozporządzeniu nr 82 z 2001 roku. Wyniki analiz wykazały, że 13 parametrów przekracza dopuszczalne normy przewidziane dla 1 klasy czystości. Te parametry to: zawiesina całkowita (TSS), biochemiczne i chemiczne zapotrzebowanie na tlen (BOD, COD), fosforany, azotany, As, Se, Cd, Mn, Cu, Pb, H₂S, bakterie E. coli i bakterie z grupy coli. Stan wód jeziornych określono jako silnie zanieczyszczone. Jakość wody jeziora Rawa Pening powinna ulec poprawie przez ograniczenie ładunku zanieczyszczeń doprowadzanych do jeziora wskutek działalności człowieka.
