Abstract

This study aims to analyze the differences in student learning outcomes using Dakonic (Chemistry Dakon) and Sempotron (Electronic Abacus) media in learning the periodic system of elements. The research employed a quantitative method with a quasi-experimental design using the Nonequivalent Control Group Design. The subjects consisted of 72 tenth-grade students of SMA Negeri 15 Semarang, divided into a control class using Sempotron and an experimental class using Dakonic. The research instrument was a learning outcome test that had been validated and tested for reliability. Data were analyzed through normality test, homogeneity test, N-Gain, and t-test. The results showed that the experimental class obtained an average N-Gain of 0.701 (high category), while the control class only reached 0.479 (medium category). The t-test also revealed a significant difference between the two classes with a significance value of 0.000 (<0.05). These findings indicate that Dakonic is more effective in improving students’ understanding of the periodic system of elements compared to Sempotron. Therefore, Dakonic can be considered as an innovative, engaging, and culturally relevant chemistry learning medium

Abstract

Tegalsari Village, Karanggede Subdistrict, Boyolali Regency, is predominantly inhabited by residents with lower-middle economic status, which affects dietary patterns and nutritional intake, especially among toddlers. Initial data indicated low maternal knowledge about balanced nutrition, minimal participation in posyandu activities, and the absence of community nutrition cadres to provide ongoing education. In response, the Community Service (PKM) team implemented the program “Strengthening Community Nutrition Cadres for Stunting Prevention,” which included education on balanced nutrition and the impacts of stunting, training on preparing balanced menus based on local wisdom, and the formation of competent nutrition cadres.The results showed a significant increase in participants’ knowledge, with the average post-test score of 80.00 rising from a pre-test score of 59.33. Most participants now fall into the “good” knowledge category, while those with “poor” knowledge decreased to 0%. The established nutrition cadres are able to disseminate information and healthy nutrition practices sustainably, as well as assist families in preparing balanced menus and monitoring child growth.This program is expected to enhance the community’s understanding of the importance of balanced nutrition, encourage healthy eating habits, and promote active participation in stunting prevention. Strengthening the capacity of cadres has the potential to improve program effectiveness holistically, ensuring that stunting prevention can be implemented independently and sustainably at the community level.
