Abstract

Introduction: Potable water needs to satisfy quality criteria for microbiological, chemical, and physical. Consuming water that fails to comply with established quality standards can lead to illnesses, including diarrhea. In Tangerang City, based on environment-related disease counseling data from 2024, diarrhea had the highest number of cases. The study examined the influence of DAM sanitary hygiene on the microbiological quality of refilled potable water and to map the distribution of DAM in Tangerang City in 2024. Methods: The study employed a quantitative analytic observation with a cross-sectional method and a secondary data analysis (SDA) with a geographic information system (GIS). Independent variable in this study is the assessment results of the sanitary hygiene DAM and dependent variable is the microbiological quality laboratory test result. The sample consisted of 104 DAM across Tangerang City. Data analysis utilized the Chi-square and binary logistic regression tests. Spatial analysis for thematic map creation was performed using QGIS. Results and Discussion: The results showed that 72.1% of DAM met the sanitary hygiene requirements but 63.5% still had microbiological contaminants. Statistical test results showed that the sanitary hygiene of DAM had a significant partial effect on the microbiological quality of drinking water with a p-value=0.002 (p<0.05). Conclusion: The study concluded that the sanitary hygiene of DAM affects the microbiological quality of drinking water. Other variabels outside the assessment aspects also contribute, such as a contact time of UV light or disinfection equipment, maintenance of filters, and water source quality.

Abstract

Food safety is the urgency behind testing preservatives, colorants, and sweeteners in snacks and measuring heavy metal levels in marine animals in maintaining public health and ensuring the quality of food consumed. The purpose of conducting food quality testing practicum is to determine the presence or absence of harmful additives that have an impact on health. This research is a descriptive study using a qualitative method using a reagent test kit for the substances to be tested. The results obtained were 5 food samples containing formalin and 1 beverage sample containing cyclamate. In addition to the hazardous food additives test, heavy metal content tests were also conducted on marine animals. The results showed that 6 samples contained lead and 2 food samples contained mercury. All ingredients or substances tested in this study, namely Borax, Formalin, Arsenic (As), Rodhamin B, Methyl Yellow, Saccharin, Cyclamate, Aspartame, Lead (Pb), and Mercury (Hg) are substances that are harmful to health especially if consumed in excessive amounts. Findings from the study indicate that there are still food producers who use hazardous food additives such as preservatives, dyes, and sweeteners in snacks. In addition to food additives, food safety can also be affected by the environment, such as the heavy metal content in seafood
