Abstract

Stunting adalah masalah serius pertumbuhan dan perkembangan anak yang memiliki dampak jangka panjang yang merugikan. Artikel ini membahas penyebab, dampak, dan upaya pencegahan stunting di Indonesia, khususnya di lingkungan Sekolah Dasar Negeri 1 Lagadar, Kabupaten Bandung. Stunting disebabkan oleh asupan gizi yang tidak mencukupi dan faktor-faktor sosial ekonomi. Tingginya prevalensi stunting di Indonesia mengakibatkan masalah kesehatan dan kecerdasan anak yang berkepanjangan. Penulis menjelaskan metode sosialisasi Perilaku Hidup Bersih dan Sehat (PHBS) sebagai upaya pencegahan stunting di sekolah. Sosialisasi melibatkan ceramah interaktif, praktik mencuci tangan, dan edukasi tentang makanan bergizi. Hasil evaluasi menunjukkan peningkatan pemahaman siswa tentang stunting dan PHBS. Selain itu, siswa juga dapat mempraktikkan mencuci tangan dengan benar sesuai panduan WHO. Dengan demikian, kegiatan sosialisasi ini diharapkan dapat membantu mengubah perilaku siswa dalam menerapkan PHBS untuk mencegah stunting. Pemahaman yang meningkat dan perubahan perilaku yang positif diharapkan akan membantu mengurangi prevalensi stunting di Indonesia.

Abstract

The abstract nature of chemistry often leads to low student comprehension, a problem exacerbated by a lack of teaching materials that connect concepts to real-world situations. This research aimed to develop a valid, practical, and effective contextual teaching module on the colloid system using Four Steps Teaching Material Development (4STMD) method. The research following the stages of Design, Development, and Evaluation (DDE). The module's unique context is the application of colloid chemistry principles to the treatment of tofu liquid wastewater using Moringa oleifera seeds as a natural coagulant. The development process followed the four stages of 4STMD: Selection, Structuring, Characterization, and Didactic Reduction. The module's quality was evaluated by three expert chemistry teachers and tested for understandability with 63 high school students. The results of the expert validation indicated that the module is Very Feasible, with high scores in content (95.2%), language (85.7%), presentation (93.7%), and graphical feasibility (85.3%). Furthermore, the student understandability test yielded an average score of 93.33%, categorizing the module as "High" and suitable for independent learning. It is concluded that the 4STMD method successfully produced a viable and effective contextual module that bridges the gap between abstract chemical concepts and their practical, sustainable applications.
