ABSTRACT Situ Cisanti has the main function which is, being utilized by the surrounding community for various activities such as plantations, fisheries and tourism activities. The many activities in Situ Cisanti have an impact on the decline in water quality in the waters of Situ Cisanti. The water quality in Situ Cisanti must meet water quality standards because Situ Cisanti is the zero point of the Citarum River so that it has a direct impact on fish farming activities and drinking water sources along the Citarum River. Determination of water quality status in a body of water can be done by several methods, one of which is the STORET Method. Through the STORET Method, the water quality status of Situ Cisanti can be determined. The method used is the survey method. Determination of sampling points is determined based on considerations of the zoning of the water body consisting of inlets, the middle of the waters and outlets. Data analysis is carried out by comparing it with water quality standards and scoring it. Based on the results, the water quality status of Situ Cisanti is categorized as "lightly to moderately polluted" with a score between -10 to -11 for class 1 water quality standards and is categorized as lightly polluted with a score of -10 for class 2 quality standards. So it can be concluded that it does not meet the quality standards set by Government Regulation Number 22 of 2021 for raw water for drinking water and fisheries activities. Keywords: Situ Cisanti.

Kata Kunci: Situ Cisanti. STORET. Kualitas Air INTRODUCTION Situ Cisanti is a form of inland public water ecosystem located in West Java Province, in Tarumajaya Village. Kertasari District. Bandung Regency. Situ Cisanti is one of the sources of the Citarum River. The Citarum River is the largest and widest river in West Java Province (Fathurrohim, 2. Situ Cisanti has seven flowing springs: Pangsiraman. Cikawedukan. Koleberes. Cikahuripan. Cisadane. Cihaniwung, and Cisanti (Diana & Pasya, 2. Situ Cisanti primarily serves as a water source and is utilized by the local community for various activities such as plantations, fisheries, and tourism. One example of plantation activity is tea plantations. Tea plantations are suspected of causing the influx of chemicals such as phosphates and nitrates into Situ Cisanti. This is clarified by (Fathurrohim, 2. , who noted that Situ Cisanti appears increasingly cloudy and contains pools of pesticide residue. Fishery activities, such as fishing, often add to the pollution burden by dumping waste, such as food scraps and plastic, into the lake. The numerous activities in Situ Cisanti have resulted in a decline in water quality. This decline in water quality in a body of water certainly impacts the existing ecosystem, such as the survival of species in Situ Cisanti and habitat destruction. One way to assess water quality in a body of water is by assessing its water quality status. Water quality status can be assessed through physical, chemical, and biological parameters, providing an overview of the extent to which Situ Cisanti can support existing activities without negatively impacting aquatic life and the environment. Water quality assessment is a crucial step in water resource management. Analysis of physical and chemical parameters is crucial to understanding the condition of water quality in Situ Cisanti. Water quality in Situ Cisanti must meet water quality standards because Situ Cisanti is the zero point of the Citarum River, directly impacting fish farming activities and drinking water sources along the Citarum River. Furthermore, poor water quality in Situ Cisanti has the potential to exacerbate water pollution in the Citarum River. According to the Decree of the Minister of State for the Environment No. 115 of 2003, determining the water quality status of a body of water can be done using several methods, one of which is the STORET method. The STORET method is used to determine water quality status by comparing measured water quality data with established water quality standards. This method is regulated in the Decree of the Minister of Environment No. 115 of 2003. Using the STORET method, the water quality status of Situ Cisanti can be determined by analyzing physical and chemical water quality parameters. Therefore, the purpose of this study was to determine the water quality status of Situ Cisanti using the STORET method based on physical and chemical parameters. RESEARCH METHODS Place and Time The research was conducted from January to February 2025 at Situ Cisanti. Pejaten Village. Tarumajaya Hamlet. Kertasari District. Bandung Regency.

It is estimated that the point with poor water conditions is due to the large amount of pesticide accumulation. Data Analysis The water quality status of Situ Cisanti was determined using the STORET method. According to Masykur et al. STORET begins with periodic sampling. Water quality is then measured based on physical and chemical parameters, as these directly impact the aquatic The results of measurements of temperature. TSS. TDS, transparency. DO, pH, and BOD are then compared with the quality standards stipulated in Government Regulation of the Republic of Indonesia Number 22 of 2021 for classes 1 and 2. The ammonia values are compared with the quality standards stipulated in Government Regulation of the Republic of Indonesia Number 82 of 2001 for classes 1 and 2.

Water Quality Status based on the STORET Method Based on the data analysis, an assessment of water quality status was carried out using the STORET method, comparing eight water quality parameters with class 1 and 2 water quality standards, presented in Table 4. e-ISSN : 2622-1934, p-ISSN : 2302-6049 Fisheries Journal, 15 . , 1777-1789. http://doi. org/10. 29303/jp. Gunawan et al. , . Table 4. Water pollution status of Situ Cisanti according to the STORET method Stasiun Class 1 Class 2 Information: Class A: very good, meets quality standards Class B: good, lightly contaminated Class C: moderate, moderately polluted Class D: bad, badly polluted Table 4 shows the results of calculations using the STORET method that the water of Situ Cisanti has experienced pollution with a pollution status categorized as "Light to moderate pollution" with a score ranging from -10 to -11 for class 1 quality standards and categorized as "Light pollution" with a score of -10 for class 2 quality standards. In addition, the results of the STORET method calculations show that station 1 is included in the "Light pollution" category while stations 2 and 3 are included in the "Light to moderate pollution" category. This shows that Situ Cisanti does not yet meet the requirements for raw water for drinking water or fish farming activities according to Government Regulation No. 22 of 2021. DISCUSSION Physical Parameters The phenomenon of the average temperature at station 1 being lower than at station 2 is caused by the absorption of solar energy by suspended particles that absorb sunlight more effectively than clear water. This is supported by the statement of Birmachu et al. , which explains that the larger the suspended particles in the water, the higher the temperature of the In addition, vegetation cover also affects the penetration of light received by the water, where station 1 is surrounded by many trees while at station 2 there are no trees. However, it can be seen that there is a decrease in temperature from station 2 to station 3. This is because station 3 is surrounded by trees and there are many branches on the water surface so that the sunlight received by the water at station 3 is less. According to de Lima et al. , branches on the water surface can affect water temperature, especially by reducing the intensity of sunlight entering the water. Although the water temperature of Situ Cisanti shows a fluctuating trend, it still meets the water quality standards set by Government Regulation No. 22 of 2021. The water temperature standard according to Government Regulation No. 22 of 2021 is a deviation of 3. Meeting these temperature parameters contributes to a favorable water temperature for fish metabolism and maintains the DO balance in Situ Cisanti. Furthermore, according to Government Regulation No. 22 of 2021, the TSS water quality standard for Class 1 is 25 mg/L, while for Class 2 it is 50 mg/L. Therefore, the maximum value at stations 2 and 3, at 26 mg/L, exceeds the water quality standard set for Class 1. However, for Class 2, both the minimum, maximum, and average values still meet water quality This is due to Situ Cisanti being surrounded by community agricultural land, which allows runoff to carry fertilizer or soil particles. This is supported by research by Tamara et al. in Lake Lut, agricultural activities around Lake Lut have caused an increase in TSS levels in the water. To ensure TSS parameters meet established water quality standards, a strategy is necessary. One such strategy is the use of a floating wetland system with Heliconia e-ISSN : 2622-1934, p-ISSN : 2302-6049 Fisheries Journal, 15 . , 1777-1789. http://doi. org/10. 29303/jp. Gunawan et al. , . densiflora plants. According to Purnamasari . , floating wetlands with Heliconia psittacorum can reduce TSS by 88% within a few weeks. Furthermore. TDS values at all stations meet water quality standards based on Government Regulation No. 22 of 2021 for class 1 and class 2. Based on Government Regulation No. 22 of 2021, the water quality standard for class 1 and class 2 is 1000 mg/L. Therefore, the TDS parameters in the water of Situ Cisanti still meet water quality standards. This is confirmed by the TDS data obtained by Hanifah et al. in Situ Cisanti, where TDS data ranged from 83 mg/L to 141 mg/L, with an average of 100. 78 mg/L and a standard deviation of 13. Meeting TDS requirements in Situ Cisanti results in low turbidity, thus optimizing sunlight penetration. Finally, the decrease in transparency values across stations is due to hydrodynamic Station 1 is located at the spring, resulting in less sediment inflow, and Station 3 is located at the outlet, resulting in sediment accumulation, resulting in lower transparency values. This is supported by the conditions at each station: Station 1 appears clear. Station 2 is greenish, and Station 3 is greenish, with visible tree branches. Furthermore, according to Hasan et al. , transparency results at Situ Cisanti show that the inlet transparency value is greater than the outlet, with the inlet transparency value ranging from 62. 83 to 90. 33 cm, while the outlet transparency value is 62 cm. Based on Government Regulation No. 22 of 2021, the water quality transparency standard for Class 1 is 10 cm, while for Class 2 it is 4 cm. Therefore. Situ Cisanti's transparency still meets the established water quality standards. Chemical Parameters Figure 6 shows that DO decreases along with the location of the research station. According to Pribadi et al. , this phenomenon occurs because aerobic microorganisms decompose organic matter by consuming DO, resulting in DO decreasing along with the water Furthermore, domestic waste and organic waste increase along with the water flow, increasing the load of organic matter that must be decomposed, gradually decreasing DO from inlet to outlet. However, according to Government Regulation No. 22 of 2021, the DO water quality standard for Class 1 is 4 mg/L and for Class 2 is 4 mg/L. Therefore, despite the decrease in DO in Situ Cisanti, the water still meets the established water quality standards. Furthermore, the increase in pH along with station location is caused by the decomposition of organic matter such as twigs and logs in the middle of the water, which causes aerobic decomposition, producing alkaline compounds. Therefore. Station 3 has the highest pH value compared to the other stations. Overall, the pH values obtained indicate that the water in Situ Cisanti meets the water quality standards set by Government Regulation No. 22 of 2021. Based on Government Regulation No. 22 of 2021, the water quality standard for pH classes 1 and 2 ranges from 6 to 9. Meeting these pH standards indicates that the stability of Situ Cisanti's aquatic ecosystem is maintained, which supports fish metabolism and the nitrification process. According to Hanunrandi et al. , a pH that meets water quality standards supports the metabolic processes of fish and other aquatic organisms, including biochemical processes such as nitrification. Figure 8 also shows that BOD decreased at station 2 but increased again at station 3. This decrease in BOD at station 2 is due to active decomposition by midges, which reduces the presence of organic matter. This is evident from the presence of tree trunks on the surface, which act as a substrate for microorganisms to decompose, enabling active decomposition. Furthermore, according to Royani et al. , the decrease in BOD in the midstream can be influenced by natural dilution by water flow which results in a reduction in organic matter in the water. Furthermore, there was an increase in BOD at station 3 due to a decrease in DO levels which caused the decomposition process to be suboptimal and organic matter accumulated at station 3. This is supported by the greenish color of the water at station 3 e-ISSN : 2622-1934, p-ISSN : 2302-6049 Fisheries Journal, 15 . , 1777-1789. http://doi. org/10. 29303/jp. Gunawan et al. , . indicating a large amount of accumulated organic matter. This is supported by the statement of Daroini and Arisandi . , who stated that stations with low DO have high BOD due to the large amount of organic matter, such as mangrove litter, which acts as a substrate for microorganism decomposition, thus increasing BOD. This is also supported by DO data obtained during the study which shows a downward trend in DO levels along with the station. Based on Government Regulation No. 22 of 2021, the BOD water quality standard for class 1 is 2 mg/L while for class 2 is 3 mg/L. Therefore, the BOD parameters of Situ Cisanti water, both the minimum, maximum, and average values, do not meet the established water quality standards for both Class 1 and Class 2. Failure to meet BOD standards can result in low DO levels in the water, which can lead to mass fish deaths. It can also impact human health. According to Napitupulu and Putra . coli and Salmonella bacteria can multiply five times faster if DO levels exceed 6 mg/L. This phenomenon can be addressed in various ways, one of which is by using aquatic plants. According to Hasanah et al. , aquatic plants such as pumice and water spinach can help reduce BOD levels in water. Finally, ammonia in water can be influenced by various factors, such as the input of organic waste in the form of fertilizer. Furthermore, low DO levels affect the nitrification process, causing ammonia to accumulate (Hendrawan et al. Figure 9 shows that ammonia levels fluctuate, with an increase at station 2 followed by a decrease at station 3. This is due to the clean and DO-rich conditions at station 1, which facilitate the smooth nitrification Therefore, the ammonia level at station 1 is the lowest. Then, an increase occurs at station 2, possibly due to a decrease in DO levels at station 2 . due to the accumulation of organic matter, which inhibits the nitrification process. Then, a decrease occurs again at station 3, caused by the flow of water out of Situ Cisanti, resulting in a lower ammonia level than at station 2. Despite the fluctuations in ammonia levels, the ammonia level in Situ Cisanti water still meets established water quality standards. Because based on the Republic of Indonesia Government Regulation No. 82 of 2001, the ammonia water quality standard for class 1 is 0. 5 mg/L while for class II it is 0. 02 mg/L. Water Quality Status based on the STORET Method The water of Situ Cisanti has been polluted, with a pollution status categorized as "Light to moderate pollution," with a score ranging from -10 to -11 for the Class 1 quality standard, and "Light pollution," with a score of -10 for the Class 2 quality standard. Furthermore, the STORET method calculation results indicate that station 1 falls into the "Light pollution" category, while stations 2 and 3 fall into the "Light to moderate pollution" category. This indicates that Situ Cisanti does not meet the requirements for drinking water or fish farming activities according to Government Regulation No. 22 of 2021. This is due to the failure to meet the TSS and BOD parameters based on the water quality standards set by Government Regulation No. 22 of 2021. This indicates that the primary source of pollution in Situ Cisanti comes from organic matter. This is supported by direct observations that found twigs at stations 2 and 3. According to Yulianti . , organic matter such as twigs and plant debris are part of the suspended solids that affect TSS values and water quality. Furthermore, the high BOD results during the study indicate that organic matter in Lake Cisanti is still abundant and has not yet degraded. Furthermore. DO values decrease with station According to Rizal et al. , a high BOD indicates the presence of abundant, poorly degraded organic matter in the water. Microorganisms decompose this organic matter using DO, so a high BOD is usually accompanied by a decrease in DO. Therefore, efforts are needed to address the failure to meet TSS and BOD parameters in Lake Cisanti. One management approach is to control pollution sources. Considering the source of pollution originating from organic matter. Lake Cisanti managers need to regularly clear tree branches in Lake Cisanti. Furthermore. Lake Cisanti managers can monitor activities e-ISSN : 2622-1934, p-ISSN : 2302-6049 Fisheries Journal, 15 . , 1777-1789. http://doi. org/10. 29303/jp. Gunawan et al. , . around the lake, such as agricultural activities. This can reduce the amount of pollutants entering the water. This approach is supported by research by Panjaitan et al. in Lake Toba, monitoring activities around the lake and controlling sources of pollution can reduce ecological pressure and improve the condition of Lake Toba's waters. Another effort that can be made is the use of aquatic plants. According to Hasanah et al. , aquatic plants such as pumice and water spinach can help reduce BOD levels in water. CONCLUSION Based on the results of the study "Determination of the Water Quality Status of Situ Cisanti Using the STORET Method", it can be concluded that the results of the analysis using the STORET method indicate that the water quality status of Situ Cisanti is categorized as "Lightly to moderately polluted" with a score between -10 to -11 for class 1 water quality standards and is categorized as lightly polluted with a score of -10 for class 2 quality standards so that it does not meet the quality standards set by Government Regulation Number 22 of 2021 for raw water for drinking water and fisheries activities. Parameters that do not meet include TSS and BOD parameters. ACKNOWLEDGEMENT The author would like to express his deepest gratitude to Dr. Heti Herawati.
