Abstract

Contamination of refill drinking water in Indonesia remains a serious public health issue. One of the main causes is weak sanitation supervision and poor hygiene practices during the water treatment process at Refill Drinking Water Depots (DAMIU). This study aims to analyze the contamination of Coliform and Escherichia coli bacteria in DAMIU across North Sumatra Province and to assess their compliance with the quality standards set by the Ministry of Health Regulation (Permenkes) No. 02 of 2023 concerning Environmental Health Quality Standards (SBMKL). The research employed a descriptive observational method with a secondary data analysis approach using microbiological laboratory test results from the Public Health Laboratory Center on 55 water samples collected from 11 districts/cities in North Sumatra Province. The results showed that most refill water samples did not meet microbiological standards, as they contained T. Coliform and E. coli exceeding the maximum limit of 0 CFU/100 ml. The highest contamination levels were found in Medan Sunggal District, Medan Selayang District, and Mandailing Natal Regency, while Toba Regency and parts of Pematang siantar City showed compliant results. The findings indicate that the majority of DAMIU in North Sumatra Province have not met microbiological quality standards, with approximately 70% of samples testing positive for T. coliform and more than 40% containing E. coli. The presence of T. coliform and E. coli in refill drinking water poses a potential risk of waterborne diseases such as diarrhea, cholera, hepatitis A, and dysentery. Therefore, regular supervision and strict implementation of hygiene and sanitatio.

Abstract

Cases of environmental pollution in Indonesia are still relatively high and are one of the causes of the increasing number of infectious diseases such as diarrhea, cholera, and hepatitis A. One of the factors that influence this condition is the low knowledge and concern of the community towards environmental sanitation, including in educational environments such as Islamic boarding schools. This study aims to determine the effect of santri's knowledge of environmental sanitation and their caring attitude towards environmental hygiene at the Daarul Istiqlal Islamic Boarding School in Medan, Patumbak District. This study used a quantitative approach with a correlational design. The population in this study were all ninth grade students as many as 128 people, with a sample of 70 students taken through random sampling techniques using the Slovin formula. The instruments used consisted of a knowledge test and an attitude questionnaire with a Likert scale. The results showed that the students' knowledge was in the excellent category with an average score of 86.64, while their caring attitude was in the good category with an average score of 75.87. Pearson Product Moment correlation analysis showed a positive and significant relationship between knowledge and students' caring attitude towards environmental cleanliness with a correlation value of 0.497 and a significance value of 0.001 (p < 0.05). This shows that the higher the knowledge of the students, the higher their caring attitude towards environmental cleanliness.
