Abstract

The process of selecting the North Sumatra Ambassador Language Finalists at the North Sumatra Language Hall is still subjective in that the assessment may not be based on established criteria or without looking objectively so that the selection process is carried out less precisely and the resulting decision is less satisfactory for the participants of the Ambassador Finalists North Sumatra Language. In this study, the authors used a decision support system with the Promethee II method to find the value of weights and criteria, and to find the final score or to find the finalist ranking of the North Sumatra Language Ambassador. Thus the Decision Support System is needed in order to help the North Sumatra Language Office in determining the Finalists of the North Sumatra Language Ambassador. To overcome these problems, it is necessary to build a decision support system application for the selection of North Sumatra Language Ambassador Finalists using the Promethee II method so that it can help and facilitate the North Sumatra Language Hall in making a decision to choose the North Sumatra Language Ambassador and the resulting decision is satisfactory.Keywords: Decision Support System, Language Ambassadors, Promethee Method ii

Abstract

Research on measuring LMS user satisfaction has been widely conducted; however, there remains a gap in the comprehensive evaluation of e-learning system usability, particularly in the context of Moodle platform adaptation in Indonesia. This study adopts a more systematic approach by employing the System Usability Scale (SUS) as the primary measurement instrument, complemented by qualitative analysis to provide a deeper understanding of the usability aspects that need improvement. The research employs a quantitative approach using survey methods to analyze user satisfaction with Moodle-based e-learning systems. This quantitative approach was chosen as it allows systematic measurement of the system's usability using the standardized System Usability Scale (SUS) instrument [12]. Several stages are involved in this study, including pre-research, instrument preparation, validity and reliability testing, data collection, and data analysis. Given the highly fluctuating and difficult-to-determine population size, the study uses snowball sampling to obtain the sample. The respondents include active university students from various higher education institutions in Indonesia who regularly use the Moodle platform for their learning activities. Other inclusion criteria include: having used Moodle for at least one semester, actively participating in online learning, and being willing to complete the questionnaire. The significance of this research lies in its contribution to generating empirical data on the usability of Moodle-based e-learning systems using the standardized SUS method. The results are expected to provide practical recommendations for improving system usability while enriching the literature on the implementation of SUS in the e-learning context in Indonesia.

Abstract

ABSTRACT This study aims to determine the effect of the Search, Solve, Create, and Share (SSCS) learning model on students' critical thinking skills in Mathematics learning for fifth graders at SDN 101775 Sampali. This research was conducted at SDN 101775 Sampali using a Quasi-Experimental Design with a Nonequivalent Control Group Design. The subjects in this study were fifth grade students at SDN 101775 Sampali, consisting of two classes totaling 62 students. Data collection techniques were carried out through observation and tests. The instrument used in this study was an essay test to measure students' critical thinking skills. The results of the study showed a significant and positive influence between before and after the implementation of the SSCS learning model in improving critical thinking skills in fifth-grade mathematics learning. This is evidenced by the results of the hypothesis test with a t-test obtained a significance value of 0.045 <0.05. This indicates that H0 is rejected and Ha is accepted. Thus, it can be concluded that there is an influence of the Search, Solve, Create, and Share Learning Model on Students' Critical Thinking Skills in Fifth-grade Mathematics Learning at SDN 101775 Sampali.

Abstract

This study addresses the low level of students’ creativity in mathematics learning, particularly in geometry, caused by conventional teaching methods that limit exploration and active participation. The purpose of this research is to determine students’ creativity before and after the implementation of the Tangram game and to analyze its effect on students’ creativity in mathematics learning. This study employed a quantitative approach with a quasi-experimental method using a One Group Pretest-Posttest design. The population and sample consisted of 20 fourth-grade students of SD Negeri 050688 Sawit Seberang. Data were collected using creativity tests covering fluency, flexibility, and originality aspects. Data analysis techniques included the Wilcoxon test and N-Gain score. The results showed a significant improvement in students’ creativity after the implementation of the Tangram game, indicated by the Wilcoxon test results where the significance value was less than 0.05 (p < 0.05). Additionally, the average N-Gain score of 55.99% was categorized as moderate, indicating that the Tangram game was sufficiently effective in enhancing students’ creativity. Therefore, it can be concluded that the Tangram game has a significant effect on students’ creativity in mathematics learning.
