Abstract

This research aims to determine the validity, practicality, effectiveness and how the students' answers process in completing the conceptual understanding ability test of the developed Articulate Storyline. This type of research is ADDIE model development research. The subjects of this research were 15 students in class VIII-2. The research results showed that the validity of the media was 85% before revision and 98% after revision from material experts and 61.67% before revision and 98% after revision from media experts on very valid criteria. The practicality of the media has met practical criteria, based on teacher responses obtained at 100% and from student responses obtained at 92.36%. The effectiveness of the media has met the effective criteria in terms of classical student learning completeness reaching 86.67%, use of research time in accordance with the RPP, and student response of 91.67%. The N-Gain test result is 0.70 in the high category. For the student answer process on the ability test (pre-test) it was 38.89%, increasing to 46.67% on the final ability test (post-test). Increasing students' ability to understand mathematical concepts strengthens the development of Articulate Storyline mathematics learning media in the classroom learning process.

Abstract

Labor scheduling is allocating human resources to work stations according to needs. To increase productivity, companies must schedule labor optimally. In allocating labor, the Hotel Menara Lexus company has implemented labor scheduling with 3 work shifts, namely morning, afternoon and night. Because scheduling is still made manually, it is possible for schedule "collisions" to occur and there is no fairness in the distribution of shifts to each employee. To solve this problem, an appropriate algorithm is needed so that the scheduling process can run optimally. The application of genetic algorithm methods in scheduling problems is able to produce good solutions using chromosome representation, determining objective function values, fitness evaluation, determining probability function values, selection process using Roulette Wheel, crossover method using one cut-point crossover, and mutation at the above level. 0.5 can then be generated. From parameter testing, the results obtained

Abstract

This study was motivated by the low understanding of mathematical concepts of class VIII students of SMP Negeri 4 Bukittinggi. Based on the results of the documentation study, the percentage of students with daily test scores below the 55 criterion ranged from 50% to 81%. Observations and interviews revealed that learning was still dominated by teachers, while students were less active in the learning process. This study aims to determine the significant effect of the Numbered Head Together (NHT) cooperative learning model on students' understanding of mathematical concepts. This experimental study used the Static Group Comparison Design. The population of the study was class VIII students of SMP Negeri 4 Bukittinggi in the 2021/2022 academic year consisting of 127 students from 4 classes. The sample was taken randomly, with class VIII1 as the experimental class and VIII2 as the control class. The research instrument was a mathematical concept understanding test. The results of data analysis using the t-test showed a calculated t value > t table (3.269 > 1.67) at a significance level of 0.05. From SPSS, a significant value of 0.02 <0.05 was obtained so that H0 was rejected and H1 was accepted. In conclusion, there is a significant influence of the NHT learning model on the understanding of mathematical concepts of class VIII students of SMP Negeri 4 Bukittinggi.

Abstract

Education serves as a fundamental pillar in national development, as it not only enhances individual capacities but also improves overall social welfare. Despite this crucial role, Indonesia continues to face disparities in both access to and quality of education among its regions, as can be seen from variations in school participation indicators and socio-economic backgrounds. To analyze these differences, this study applied the K-Means Clustering method to categorize provinces in Indonesia using six variables: School Participation Rate, Net Enrollment Rate, Gross Enrollment Rate, Poverty Rate, High School Ratio, and Teacher Ratio. To identify the most suitable number of clusters, three validation indices were utilized, namely Dunn Index, C-Index, and Davies-Bouldin Index, with cluster counts tested from three to six. The results indicated that the best clustering solution was five clusters, as reflected in the highest Dunn Index (0.1569), lowest C-Index (0.0321), and lowest Davies-Bouldin Index (0.5062). The robustness of this clustering was further supported by the ratio between within-cluster and between-cluster standard deviation (S(w)/S(b) = 0.33). Each cluster revealed unique characteristics of education and socio-economic conditions, where Cluster 4 displayed the most favorable outcomes with high participation and low poverty levels, whereas Cluster 5 highlighted the weakest performance across all observed indicators.

Abstract

This research was conducted on fourth-grade students of SD Negeri 01 Dagen Karanganyar with the aim of identifying the improvement of critical thinking skills in IPAS learning by applying the Cooperative Learning Model of the Teams Games Tournament (TGT) type during the 2024/2025 academic year. The study involved 25 students, consisting of 16 male students and 9 female students. This research belongs to quantitative research with a One-Group Pre-Test Post-Test Design. The research procedure began with administering a tryout test to determine the number of valid items to be used. The validity test results showed that 20 items met the validity criteria during the tryout. Data analysis was conducted using the One-Sample Shapiro-Wilk test for normality and the Paired Sample T-Test for hypothesis testing. Based on the analysis, the results showed a significance value of < 0.000 with a significance probability of < 0.05. Therefore, the findings are consistent with the hypothesis, namely: “There is an effect of using the Teams Games Tournament (TGT) Learning Model in IPAS learning on the critical thinking skills of fourth-grade students at SD Negeri 01 Dagen Karanganyar in the 2024/2025 academic year.” This indicates that the TGT model can enhance students’ ability to think critically, helping them develop essential skills in problem-solving, analysis, and decision-making, which are crucial for their academic success and future learning processes.
