Opis:: Human activities may cause degradation of water quality. For monitoring purpose, it is necessary to know the level of pollution that occurs in water in order to sustain the function of the aquatic ecosystem. The purpose of this study was to determine the level of water pollution of Menjer Wonosobo Lake based on the physical, chemical, and biological parameters to evaluate the best function of the water to support the human activities. The study was conducted for three months (July to September 2020). Water sampling was carried out at seven stations; then, the measurement results were compared with the water quality standards based on Government Regulation No. 22 of 2021. Determination of water quality was carried out using the STORET method. The results showed that there were 7 parameters that exceeded the water quality standards, namely TSS, BOD, COD, DO, N, P and Coliform. The status of water quality was at a moderately polluted level and only functions for the needs of category 3, i.e. for freshwater fish cultivation, for irrigating plants, and or other purposes. Therefore, it was necessary to manage Menjer Lake to improve its water quality.

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.

Batujai reservoir
Opis:: Batujai reservoir is located in Central Lombok Regency, Indonesia. The government and local people use it for hydropower generation, drinking water, agricultural irrigation, fish farming, and tourism. The phenomenon of growing population and increasing industrial activities in the catchment area of Batujai reservoir always result in the discharge of various pollutants into the aquatic environment and cause the blooming of water hyacinth over almost 30% of the reservoir area. The aim of this study was to determine the water pollution index of Batujai reservoir. The samples were analysed for the following parameters: pH, temperature, DO, COD, BOD, TSS, and heavy metals. The research was done by using purposive sampling method and determination of water quality status with STORET method based on Government Regulation No. 82/2001. The measurement results show that the physical and chemical parameters of the Batujai reservoir water do not exceed the quality standard are the temperature (29 to 32°C); pH (6.6 to 7.5 mg/L); nitrate (0.421 to 0.546 mg/L); Cd (0.0005 to 0.005 mg/L); Cr (<0.001 to 0.018 mg/L); and the parameters that exceed quality standards are DO (3.8 to 4.9 mg/L); BOD (3.03 to 4.21 mg/L); COD (6.8 to 10.1 mg/L); phosphate (0.181 to 0.237 mg/L); and Pb (0.14 to 0.24 mg/L). The water quality status of Batujai reservoir was heavily polluted for standard quality on class I, II, III and moderately polluted for class IV.

Opis:: Warna and Pengilon Lakes are very close to each other and connected with the sill, a famous tourist destination in the Dieng Plateau Java. Land-use changes are the main problem that affected the lakes. The conversion of forest into an agricultural area had induced erosion and increased the volume of nutrients discharged to the lake due to high use of fertilisers in potatoes farms. In the dry seasons, water from those lakes was pumped to irrigate agricultural land. This study aimed to determine the water quality of Warna and Pengilon Lakes based on physical, chemical parameters, and phytoplankton communities. Water samples were collected from 4 sites at each lake to analyse biological oxygen demand (BOD), chemical oxygen demand (COD), ammonia, nitrate, nitrite, and total nitrogen (TN). Temperature, pH, dissolved oxygen (DO), turbidity, and conductivity (EC) were measured in-situ. During this research, turbidity and BOD in Warna and Pengilon Lakes exceeded the Indonesian water quality standard. Based on the STORET method, the water quality of Lake Warna was assessed as highly polluted for all classes. However, based on the pollution index (PI), Lake Warna was slightly to moderately polluted, as well as the saprobic index was in the β-mesosaprobic phase. Based on the species diversity index of phytoplankton, both Warna and Pengilon Lakes were moderately polluted. The long-term monitoring studies are necessary as an early warning sign of water quality degradation. Therefore, they provide insight into the overall ecological condition of the lake and can be used as a basis for developing suitable lake management.
