Abstract

Penelitian ini bertujuan untuk menganalisis pencemaran bakteri Escherichia coli (E. coli) pada air tanah di Kelurahan Bidara Cina, Jakarta Timur yang merupakan wilayah padat penduduk dan rawan banjir. Metode yang digunakan adalah deskriptif kuantitatif dengan parameter yang digunakan adalah buffer dengan interval 100 meter dari Sungai Ci Liwung, sumber air bersih, kepadatan penduduk, kerapatan bangunan melalui citra satelit Landsat 8 dengan teknik NDBI, tinggi muka air tanah, hasil uji air di laboratorium terhadap 22 sampel dan analisis berdasarkan Peraturan Menteri Kesehatan Nomor 2 Tahun 2023. Hasil penelitian menunjukan bahwa lima titik sampel terindikasi tercemar bakteri Escherichia coli (E. Coli) dengan konsentrasi tertinggi sebesar 18,2/100 ml pada Rukun Tetangga 02, Rukun Warga 07 yang berada sangat dekat di dalam radius buffer 0 – 100meter dari Sungai Ci Liwung dan memiliki kerapatan bangunan yang tinggi, pencemaran disebabkan oleh faktor banjir, buruknya sanitasi, serta aliran limbah domestik ke sungai. terdapat pula titik sampel di dalam radius buffer yang sama (0–100 meter) yang menunjukkan hasil tidak terkontaminasi karena kondisi lingkungan yang lebih terjaga, seperti adanya sistem septic tank dan drainase yang baik,walaupun kerapatan bangunan yang tinggi sehingga memungkinkan air tanah tidak langsung terpapar oleh limbah permukiman. Meskipun berada jauh dari Sungai dan masuk kedalam zona 100 – 200 meter, rumah susun di RW 16 juga menunjukan kontaminasi akibat kondisi lingkungan yang tidak higenis berdasarkan hasil observasi lapangan. Seluruh sampel yang tercemar melampaui ambang batas baku mutu berdasarkan Peraturan Menteri Kesehatan Nomor 2 Tahun 2023. Temuan ini menegaskan perlunya pengawasan kualitas air tanah dan penyediaan sumber air bersih altenatif bagi masyarakat terdampak. ***** This study aims to analyze the contamination of Escherichia coli (E. coli) bacteria groundwater in Bidara Cina Subdistrict, East Jakarta, an area characterized by high population density and frequent flooding. A descriptive quantitative method was employed, utilizing parameters such as 100-meter interval buffer zones from the Ci Liwung River, sources of clean water, population density, building density through Landsat 8 satellite imagery using the Normalized Difference Built-up Index (NDBI), groundwater table depth, and laboratory testing results from 22 water samples. The analysis was conducted based on the Indonesian Minister of Health Regulation No. 2 of 2023. The results indicate that five sampling points were found to be contaminated with Escherichia coli, with the highest concentration reaching 18.2/100 ml in Neighborhood Unit (RT) 02, Community Unit (RW) 07, which lies within the 0–100 meter buffer zone from the Ci Liwung River and is characterized by high building density. The contamination was attributed to flooding, poor sanitation, and domestic wastewater discharge into the river. However, some sampling points within the same buffer zone (0–100 meters) showed no contamination, likely due to better-maintained environments, such as the presence of septic tank systems and proper drainage infrastructure, which minimized direct exposure of groundwater to settlement waste despite high building density. Additionally, a contaminated sample was identified in RW 16, located within the 100–200 meter buffer zone, likely due to unhygienic living conditions in the low-cost apartment complex, as observed during field surveys. All contaminated samples exceeded the permissible limits set by the Indonesian Minister of Health Regulation No. 2 of 2023. These findings underscore the urgent need for groundwater quality monitoring and the provision of alternative clean water sources for affected communities.
