Abstract

Situ Bambon in Ciracas, East Jakarta, is utilized by the local community for daily activities ranging from recreation, angling, to net fishing. The community frequently utilizes the areas around the inlet, midstream, and outlet to catch fish. This study aims to evaluate the content of the microbiological indicator E. coli and heavy metal levels in edible fish from Situ Bambon Ciracas to obtain a comprehensive Health Risk Assessment. The results showed that the microbiological contamination levels through the Escherichia coli indicator in edible fish ranged from <1.8 to 13.9 MPN/g, indicating that fish samples in the inlet 1 and outlet 2 areas failed to meet food safety standards (< 3 APM/g). The worst concentrations of Cadmium (Cd) and Lead (Pb) in edible fish from Situ Bambon were found in the inlet 2 area, with a Cd value of 0.83 mg/kg and a Pb value of 0.80 mg/kg. The obtained Cd and Pb contamination levels exceeded the Maximum Contaminant Limits (MCL) established by PerBPOM Number 9 of 2022, where Cd was approximately 8.3 times higher, while Pb exceeded the limit by about 2.7 times. The Health Risk Assessment (HRA) indicated that the Hazard Index (HI) value of 1.489 exceeded the allowable tolerance threshold of 1.0. Risk contribution analysis showed that Cd accounted for 51.0% of the total HI risk, while Hg contributed 35.0%. Furthermore, the carcinogenic risk (cancer) was evaluated through the Total Risk (TR) for Cadmium (Cd) because it possesses the highest Slope Factor (SF) of 0.38 (mg/kg-day)⁻¹, calculated based on the Lifetime Average Daily Dose (LADD) and SF, yielding a result of 3.37 x 10⁻⁷. This value remains below the internationally acceptable carcinogenic risk threshold of TR < 10⁻⁶. The environment-fish-human exposure cycle in Situ Bambon has reached a hazardous threshold and demands top-priority intervention to protect public health.

Abstract

The availability of clean water that meets quality standards in primary healthcare facilities is a fundamental requirement to prevent nosocomial infections and ensure patient safety. This study aims to characterize the microbiological quality and physico-chemical parameters of clean water within the Kalideres Community Health Center (Puskesmas) and its supporting units, based on the standards of the Minister of Health Regulation Number 2 of 2023. Water sampling and testing across 11 locations were conducted using the aseptic grab sampling method, in compliance with a combination of international ISO standards, Indonesian National Standards (SNI), APHA Standard Methods, and the laboratory's internal Work Instructions (IK). The results indicate significant water quality degradation, particularly regarding microbiological parameters, where locations such as the Pegadungan 1 Supporting Health Center (Pustu) exhibited Total Coliform levels exceeding >1000 colonies/100ml, and the Kalideres Community Health Center unit was found to be contaminated with both Total Coliform and E. coli at concentrations surpassing >1000 colonies/100ml. Physical parameters showed critical values for turbidity at Pustu Kamal 2, reaching 19.10 NTU, which far exceeds the 3 NTU regulatory limit. Chemically, Manganese (Mn) concentrations were detected exceeding the 0.1 mg/L threshold at Pustu Pegadungan 4 (0.2455 mg/L) and Pustu Pegadungan 2 (0.1227 mg/L). In conclusion, the water quality in the majority of primary healthcare facilities in the Kalideres region is in a concerning state due to massive bacteriological contamination and non-compliance with several physico-chemical parameters. This situation underscores the urgent need for technical interventions, including the implementation of water treatment systems and more rigorous disinfection protocols, to mitigate health risks for both medical staff and the general public.

Abstract

DKI Jakarta faces increasingly complex environmental problems, including annual floods, air pollution that is classified as hazardous, waste crisis, land subsidence, and degradation of green open spaces. As a city with a majority Muslim population, DKI Jakarta holds great potential in environmental management based on Islamic values and the local wisdom of urban Muslim communities. This study aims to analyze the dynamics of urban environmental problems in DKI Jakarta and identify the strategies of urban Muslim communities in responding to the crisis through a local wisdom approach. The method used is qualitative research with a case study approach and community ethnography. Data were collected through participatory observation, in-depth interviews with 45 key informants consisting of mosque administrators, community leaders, Muslim environmental activists, and residents, and focus group discussions in three areas of DKI Jakarta (North Jakarta, West Jakarta, and South Jakarta). The results of the study show that the urban Muslim community in DKI Jakarta has developed a mosque-based environmental management model, integrating the values of fiqh al-bi'ah (environmental fiqh), the concept of caliph fil ardh, amanah, and mizan in daily practice. Featured programs include mosque waste banks, mosque community-based urban agriculture, ablution water management for irrigation, and post-Friday tree planting movements. These findings indicate that the integration of Islamic local wisdom with modern environmental programs can be an effective model of sustainable urban environmental management.
