Abstract

The present study investigates variations in the quality of rainwater, with a focus on the materials and maintenance practices employed in rainwater harvesting (RWH) systems within Ploso Hamlet, Plosobuden Village, Lamongan Regency. The aim of the present study is to monitor pH levels and to identify the presence of total coliform contamination. The present study employed a descriptive quantitative approach, with 30 RWH units being purposively selected from a total of 106. The data were collected through three means: observation, in-depth interviews, and laboratory testing. The result of this study shows that rainwater was contaminated with coliform bacteria, with a mean value of 3.6 MPN/100 ml and a maximum value of >1600 MPN/100 ml, which exceeds the standard for drinking water (0 MPN/100 ml). Furthermore, 48.3% of samples exhibited a pH value that exceeded the acceptable range, with the highest recorded value being 10.7.  Maintenance was substandard, with 66.7% of respondents admitting to cleaning their tanks only once a year. Furthermore, none had received education on proper maintenance. In conclusion, the analysis indicates that harvested rainwater in Ploso Hamlet does not conform to the criteria for direct consumption. The study identifies the presence of biological contamination and improper pH levels as the primary causes of the water's unsuitability for human consumption. It is recommended that the knowledge base be augmented through the implementation of a health education programme, complemented by enhanced filtration measures.

Abstract

Pesticide exposure remains a major occupational health problem, with the World Health Organization (WHO) reporting between 1 and 5 million cases of pesticide poisoning annually among agricultural workers. This study aimed to analyze the risk factors associated with pesticide poisoning by conducting a meta-analysis of published research. The meta-analysis was performed in four stages: data abstraction, statistical analysis using JASP Version 0.18.3, heterogeneity testing, and publication bias assessment. The random-effects model was applied to the variables of Personal Protective Equipment (PPE) use and length of work, as the heterogeneity test indicated significant variation between studies (p = 0.001). In contrast, the fixed-effects model was used for individual hygiene (p = 0.006). Egger’s test showed no indication of publication bias for PPE use (p = 0.356) and length of work (p = 0.395). The results revealed that PPE use increased the risk of decreased cholinesterase levels by 1.584 times, poor individual hygiene by 1.954 times, and working more than 5 hours by 1.665 times. In conclusion, individual hygiene was identified as the most significant risk factor. Farmers who neglect personal hygiene practices, such as bathing after spraying or changing clothes immediately, face a substantially greater risk of reduced cholinesterase levels due to pesticide poisoning.
