Abstract

Background: Balanced nutrition education is an essential effort in preventing obesity, especially in adolescents who are vulnerable to nutritional problems due to unhealthy diets and a lack of knowledge. This study aims to determine the effectiveness of Android-based e-pocket books in improving the understanding of balanced nutrition among adolescents in Yogyakarta. Methods: This study employed an experimental design with control groups, utilizing pre-tests and post-tests. Conducted from February to March 2023 in a high school in Yogyakarta, Indonesia, the research established a minimum sample size of 27 students per group through the Lemeshow formula and multistage sampling. Inclusion criteria required students to have Android phones, to consent to participate, to attend the study, and to complete data collection. The treatment group received education via e-pocket-book media, while the control group used e-leaflets. Knowledge was measured at three points: before the intervention, immediately after (post-test 1), and nine days later (post-test 2). Data analysis was performed using the Wilcoxon and Mann-Whitney tests with SPSS software. Results: The knowledge score of the treatment group increased from 76.3 (pre-test) to 93.8 (post-test 1) and 91.3 (post-test 2). The control group increased from 73.8 (pre-test) to 82.5 (post-test 1) and 81.3 (post-test 2). The increase in knowledge was more significant in the treatment group, showing that e-pocket-books were more effective than e-leaflets. Conclusion: Android-based e-pocket-books improve adolescents' knowledge of balanced nutrition more than e-leaflets. Digital technology in nutrition education has great potential to be applied in schools. Further research is needed to evaluate the long-term impact on nutritional behavior.

Abstract

ABSTRAK Latar Belakang: Menurut Survei Kesehatan Indonesia tahun 2023, sebanyak 15,5% remaja putri menderita anemia, sehingga anemia sebagai suatu masalah kesehatan yang signifikan. Salah satu faktor yang berkaitan dengan anemia remaja adalah rendahnya pengetahuan dan kepatuhan konsumsi Fe.Tujuan: Mengevaluasi efektivitas edukasi gizi menggunakan e-booklet dibandingkan dengan media slide dalam meningkatkan pengetahuan dan sikap terkait anemia.Metode: Penelitian ini merupakan penelitian quasi eksperimental dengan desain pretest-posttest control group. Penelitian dilakukan pada bulan Maret-April 2024, melibatkan 85 siswi SMP di Yogyakarta, yang dibagi ke dalam kelompok intervensi (e-booklet dan media slide) dan kelompok kontrol (media slide). Data tentang pengetahuan dan sikap dikumpulkan menggunakan kuesioner terstruktur pada tiga tahap: pretest, posttest-1, dan posttest-2. Analisis statistik yang digunakan adalah paired t-test, uji wilcoxon, independent t-test, dan uji mann-whitney.Hasil: Hasil penelitian menunjukkan peningkatan yang signifikan dalam skor pengetahuan pada kedua kelompok, dengan kelompok intervensi mencapai skor post-test yang lebih tinggi (89,1 vs 78,8; p<0,05). Meskipun kedua kelompok menunjukkan sedikit peningkatan dalam hal sikap, perubahan yang diamati tidak mencapai signifikansi secara statistik. Temuan ini menyoroti efektivitas e-booklet sebagai alat pembelajaran digital, yang menawarkan fleksibilitas dan konten mendalam yang mendukung pembelajaran mandiri.Kesimpulan: Penelitian ini menggarisbawahi potensi e-booklet untuk mengatasi kesenjangan pengetahuan tentang anemia di kalangan remaja. Pembuat kebijakan sebaiknya mengintegrasikan e-booklet ke dalam program pendidikan kesehatan nasional dan menggabungkannya dengan metode offline yang interaktif untuk meningkatkan perubahan pengetahuan remaja.KATA KUNCI: anemia; e-booklet; pengetahuan; remaja putri; sikap ABSTRACTBackground: Based on Indonesia Health Survey 2023, 15,5% female adolescents suffer from anemia, as a significant health problem. This is due to lack of knowledge and low compliance of Fe consumption. Objectives: To evaluate the effectiveness of nutrition education using e-booklets compared to slide media in improving anemia-related knowledge and attitudes.Methods: This was a quasi-experimental design with a pretest-posttest control group, conducted in March–April 2024, involving 85 junior high school girls in Yogyakarta, divided into intervention (e-booklet and slide media) and control (slide media) groups. Data on knowledge and attitudes were collected using structured questionnaires at three points: pretest, posttest-1, and posttest-2. Statistical analyses included paired t-tests, Wilcoxon, independent t-tests, and Mann-Whitney tests.Results: The results showed a significant improvement in knowledge scores in both groups, with the intervention group achieving higher post-test scores (89.1 vs. 78.8; p<0.05). Although both groups demonstrated a slight improvement in attitudes, the observed changes did not reach statistical significance. The findings highlight the effectiveness of e-booklets as a digital learning tool, offering flexibility and in-depth content that supports independent learningConclusions: This study underscores the potential of e-booklets to address knowledge gaps about anemia among adolescents. Policymakers should integrate e-booklets into national health education programs while combining them with interactive offline methods to enhance attitude changes.KEYWORDS: anemia; attitude; adolescent girls; e-booklet; knowledge
