Abstract

Primary school students' understanding of science concepts remains low due to teacher-centered learning and minimal use of supporting media. This condition indicates the need for a learning model that can increase active participation and facilitate meaningful inquiry activities. This study aims to determine the effect of the PhET Simulation-assisted Problem Based Learning model on the ability to understand science concepts in energy change material. This study used a quantitative method with a One Group Pretest Posttest Design involving 22 fourth-grade students at an elementary school in Purwakarta. The research instrument was a multiple-choice test based on seven concept comprehension indicators. The data were analyzed using descriptive statistics, Shapiro Wilk normality test, Wilcoxon test, and N Gain calculation. The results showed an increase in conceptual understanding after the learning model was implemented, as indicated by an increase in the average pretest score to the average posttest score and an N Gain score of 0.73 in the high category. The Wilcoxon test confirmed a significant difference between the initial ability and the ability after the treatment. These findings confirm that PhET Simulation-assisted Problem Based Learning is effective in supporting science concept comprehension and has the potential to be a more interactive and meaningful learning alternative for elementary school students.

Abstract

This study aims to analyze the level of consumer satisfaction with Crafty Puff products at the Elementary School Teacher Education Program (PGSD) Student Bazaar. This study uses a quantitative descriptive method with data collection techniques in the form of a five-point Likert scale questionnaire given to consumers who purchased the product. There were 23 respondents in this study, selected using accidental sampling techniques. The aspects analyzed include product quality, design, price suitability, purchase satisfaction, repurchase intention, willingness to recommend the product, and service. The data obtained were analyzed using descriptive statistics by calculating the average value for each assessment aspect. The results showed that the level of consumer satisfaction with Crafty Puff products was in the Very Good category with an overall average score of 4.86. The aspects of product neatness and durability, price suitability to quality, and service received the highest scores, while the aspect of using quality materials was in the Fair category. Based on these results, it can be concluded that Crafty Puff products have been able to meet consumer expectations, but efforts to improve material quality are still needed to support competitiveness and future product development.
