Edukasi Perilaku Hidup Bersih dan Sehat (PHBS) pada SDN Sukorejo 02 Jember Menggunakan Media Poster dengan Demonstrasi Interaktif pada Penggunaan Bank Sampah

Abstract

This study aimed to determine the effectiveness of education on Clean and Healthy Living Behavior and waste sorting through poster media and interactive demonstrations using a waste bank in improving elementary school students knowledge. This study employed a quantitative approach with a quasi-experimental design using a one-group pre-test and post-test design. The study was conducted among students of SDN Sukorejo 02 Jember, involving 61 respondents selected using total sampling. Data were collected using a questionnaire consisting of 20 multiple-choice questions administered before and after the educational intervention. The education was delivered through poster-based materials accompanied by interactive demonstrations on waste management and waste sorting using a waste bank. Data were analyzed using the Wilcoxon Signed-Rank Test because the pre-test and post-test data were not normally distributed. The results showed that 41 students experienced an increase in knowledge scores, 6 students experienced a decrease, and 14 students showed no change. The Wilcoxon test indicated a significant difference between students knowledge before and after the educational intervention. Therefore, the combination of poster media and interactive demonstrations through a waste bank can serve as an effective educational approach to improve students knowledge of clean and healthy living behavior and waste sorting from an early age.
