PENGARUH PENGGUNAAN APLIKASI KALENDER PINTAR (KALPIN) TERHADAP PENINGKATAN SELF EFFICACY PENDERITA HIPERTENSI DI DESA KALIANGKRIK

Abstract

Hypertension is one of the dangerous diseases, earning the nickname "The Silent Killer." Hypertension can be controlled with good self-management. Factors influencing hypertension self-management include age, gender, occupation, family support, level of knowledge, and self-efficacy. Self-efficacy refers to an individual's belief that determines the extent of their ability and motivation in managing hypertension. Kalpin (Smart Calendar) is an Android-based mobile application that provides essential features to support self-management for hypertension patients. This study aims to determine the extent of the impact of using the Smart Calendar (Kalpin) application on improving the self-efficacy of hypertension patients in Kaliangkrik Village. The research design applied a pre-experimental approach with a single group (one group pretest-posttest without control group). The sampling technique used was purposive sampling with non-probability sampling. The research instrument used was a questionnaire titled "Self-Efficacy for Managing Hypertension," with a sample size of 44 hypertension patients in Kaliangkrik Village. The hypothesis test results using paired t-test showed a p-value of <0.001 (p-value = <0.05), indicating that there is an effect of using the Smart Calendar (Kalpin) application on improving the self-efficacy of hypertension patients in Kaliangkrik Village. However, the calculation of the effect size using Cohen's d showed 0.01, indicating a very small effect. This means that while the use of the Smart Calendar (Kalpin) application does affect the self-efficacy improvement of hypertension patients in Kaliangkrik Village, the effect is very small. Therefore, the use of the Smart Calendar (Kalpin) application influences the improvement of self-efficacy in hypertension patients in Kaliangkrik Village, but the influence is very minimal.
