The incidence of diarrheal disease can be influenced by optimal or inadequate access to clear water. This study aims to determine the relationship between family access to clear water and the incidence of diarrheal diseases in the working area of the Sumbersari Health Center, Jember Regency. This study was a non-experimental analytic research with a case-control design. The sample consisted of 140 participants in the case group and 140 participants in the control group, selected by the simple random sampling technique. Participants who met the inclusion and exclusion criteria were recruited into the study. Data collection tools included a demographic characteristics questionnaire, a questionnaire on clear water access, and a questionnaire about diarrhea disease incidence. Data analysis was performed using the Chi-square test (P<0.05). The results showed that most of the respondents had optimal access to clear water (31.1% in the case group and 42.9% in the control group). Diarrhea sufferers were mostly in the early adult category (21.8%). Then, there is a significant relationship between family access to clear water and the incidence of diarrheal disease in the Sumbersari Public Health Center, Jember Regency (P<0.001; OR: 0.274).
