Abstract

This study aims to investigate the effect of the Problem-Based Learning (PBL) model assisted by Wordwall media on the mathematics learning outcomes of fifth-grade students at SD GKPS Saribudolok, focusing on the topic of perimeter and area of plane figures. This research employed an experimental method with a One Group Pretest-Posttest Design without a control group. A total of 36 students from class V-A participated as research subjects. Data were collected through pretests, posttests, and student response questionnaires. Data analysis was conducted using the Shapiro-Wilk normality test and one-sample t-test with the assistance of SPSS version 25. The results indicate a significant improvement in students' learning outcomes after the implementation of the PBL model assisted by Wordwall. The average pretest score of 59.33 (categorized as poor) increased to 79.88 (categorized as good) in the posttest, with 75% of students achieving mastery learning above the minimum competency criteria. Normality tests confirmed that the data were normally distributed (p > 0.05), and the t-test results showed that tcount ≥ ttable (3.820 ≥ 2.030) with a significance value of 0.001 < 0.05, indicating a positive and significant effect of using PBL with Wordwall on mathematics learning outcomes. Furthermore, students’ responses toward the learning model were categorized as very good (mean = 92.16). Thus, PBL assisted by Wordwall can be considered an effective learning strategy to improve mathematics learning achievement and student motivation.

Abstract

This study aims to determine the effect of the Problem-Based Learning model on third-grade students' mathematics learning outcomes at SDN 2 Biskang in the 2024/2025 academic year. This study uses a quantitative method and a pre-experimental research design. The population in this study consists of all third-grade students at SDN 2 Biskang. The sample was taken using non-probability sampling, specifically a convenience sampling, in which the population served as the sample, consisting of 23 third-grade students. To determine the students' initial abilities, the researcher administered a pretest with an average score of 59.69, which was categorized as poor. After the researcher applied the Problem-Based Learning model, students' learning outcomes improved, with an average score of 81.26, indicating good performance. This research can be supported by the correlation coefficient of 0.960, which indicates that rhitung (0.960) ≥ rtabel (0.184), so Ha is accepted. Thus, the Problem-Based Learning model strongly influences the learning outcomes of third-grade students at UPTD SPF SD Negeri 2 Biskan. As seen from the t-test results, 3.783 ≥ 2.080, indicating that Ha is accepted. This shows a significant positive influence of the Problem-Based Learning model on the learning outcomes of third-grade students at SDN 2 Biskang for the 2024/2025 academic year.

Abstract

Household waste is one of the major contributors to environmental problems in densely populated areas, including Kenangan Village in Percut Sei Tuan District. Limited waste management systems have led to the accumulation of organic waste, environmental pollution, and declining public health. At the same time, the rising cost of commercial animal feed has become an economic burden for low-income families. This community service program aims to provide an integrated solution through training on Black Soldier Fly (BSF) larvae cultivation to convert organic waste into animal feed and organic fertilizer. The implementation methods included lectures, discussions, demonstrations, hands-on practice, and field mentoring. The results indicate an improvement in the community’s understanding of organic waste processing, significant reduction of organic waste volume, and the production of maggot culture as livestock feed and organic fertilizer. In addition, participants were motivated to initiate small businesses based on maggot production and its residue. This program has proven to be effective as a circular economy solution that integrates waste management, household economic improvement, and community empowerment. The activity is recommended for broader and continuous implementation.
