Abstract

Chronic kidney disease (CKD) has become an emerging occupational health concern, particularly among workers exposed to high temperatures. This study aimed to determine the prevalence of CKD among workers in a rayon factory in West Java, Indonesia, and evaluate its association with occupational heat exposure. A retrospective cohort study was conducted using secondary data from the company’s annual medical check-up records (2022–2023) and workplace heat stress measurements obtained in 2017 using the Quest Temp Wet-Bulb Globe Temperature monitor. Workers who completed medical examinations in both years and gave written informed consent to participate in the study were included. CKD was defined as a serum creatinine level >1.2 mg/dL and an estimated glomerular filtration rate <60 mL/min/1.73 m² in two consecutive years. Chi-square tests were used for bivariate analysis, and multivariate logistic regression was performed to obtain adjusted odds ratios (ORs). Of 675 eligible workers, male constituted the majority (99.7%) and 49% were older than 40 years. Most workers (96.1%) were exposed to workplace temperatures above 28°C, and obesity (47%), hypertension (16.7%), and diabetes mellitus (5.5%) were common comorbidities. The prevalence of reduced kidney function was 5.5%, with heat exposure of 28.2–30°C associated with an OR of 4.5 (95% CI: 1.372–14.792). The prevalence of CKD was 0.9%, and heat exposure in the same temperature range demonstrated an OR of 8.958 (95% CI: 1.207–66.515). However, the association was not statistically significant after adjusting for age, obesity, and hypertension. These findings suggest that occupational heat exposure may contribute to early kidney impairment, highlighting the need for heat mitigation strategies and routine worker health monitoring in industries where workers are at risk of heat exposure.

Abstract

The Ciliwung River Basin is a strategic watershed with significant ecological, social, and economic functions, yet it is increasingly threatened by land use change, rapid urbanization, and water pollution, particularly in the Jakarta metropolitan area. This study aims to assess the water quality condition of the Ciliwung River based on real time monitoring data from the ONLIMO system and to examine spatial and temporal variations in water quality status along the middle and downstream segments. A descriptive quantitative approach was applied using secondary data obtained from three ONLIMO monitoring stations, namely Masjid Istiqlal, Pintu Air Manggarai, and Kelapa Dua Srengseng Sawah, during the period of 6–12 May 2025. The analyzed parameters included temperature, dissolved oxygen, Biochemical Oxygen Demand, nitrate, ammonia, and other relevant physicochemical indicators. The results indicate that the water quality of the Ciliwung River generally falls within lightly to moderately polluted categories, with higher pollution levels observed in the middle segment of the river. Critical parameters influencing pollution status include Biochemical Oxygen Demand, nitrate, ammonia, and consistently low dissolved oxygen levels. These findings demonstrate that pollution in the Ciliwung River is persistent and cumulative, highlighting the urgency of integrated watershed management, strengthening real time water quality monitoring, and enhancing cross sector collaboration to support effective pollution control and sustainable river restoration.

Abstract

Climate change in Indonesia has a significant impact on public health due to extreme weather that triggers various diseases, such as diarrhea, influenza, pruritus, ARI, malnutrition, and stress. This study aims to design and implement a web-based expert system with the Forward Chaining method to help the community make early diagnoses of diseases affected by climate change. The research method uses a descriptive design and a cross-sectional approach. The location of the study was carried out at the Mekarmukti Health Center, North Cikarang with a sample consisting of 100 patients who experienced symptoms of climate-related diseases and were selected using the Simple Random Sampling technique. Data were collected through observation, interviews, and literature studies, then the questionnaire data were analyzed using the Chi Square test to evaluate the level of user satisfaction with the expert system. The results of the study showed that this system was able to effectively diagnose diseases due to climate change such as pruritus (P01), diarrhea (P02), and influenza (P03) which are commonly found in the Cikarang area. This system has proven to be useful as an information technology innovation that provides accurate symptom and diagnosis information like an expert. In conclusion, this expert system can be widely accessed by the public and functions as an early diagnosis aid in health care facilities in dealing with diseases impacted by climate change.
