Furthermore, this study used a descriptive analitic research design with a cross-sectional approach conducted on seventy-seven samples under the inclusion criteria with a random sampling technique. The questionnaires used in this research were the Self-Control questionnaire and Nomophobia questionnaire. The self-control and Nomophobia correlation analysis used a Chi Square statistic test, with a significance level of 0.05. The result showed that 33.8% (twenty-six respondents) had good self-control and 66.2% (fifty-one respondents) had poor self-control. Fifty-two respondents (67.5%) experienced Nomophobia, while twenty-five respondents (32.5%) did not experience Nomophobia.
