Abstract

The preparation of teaching and learning schedules is often problematic, one of the reasons being the limited number of teachers, which means that one teacher has to teach several classes at the same time. This research is an applied study that aims to obtain a teaching and learning schedule without overlap by applying graph coloring using the Welch-Powell Improvement method. Graph coloring using the Welch-Powell Improvement method is a solution to solve scheduling problems at SMAN 7 Mataram. Based on the scheduling data, an adjacency matrix with a size of 898×898 and a chromatic number of 27 was obtained. The adjacency matrix was determined with the help of the Python programming language. The schedule was compiled by first creating a scheduling conflict graph based on the lesson schedule data, then coloring the graph using the Welch-Powell Improvement algorithm. Based on the coloring results obtained, the schedule was compiled by considering each node color. Subjects with the same color were scheduled at the same time and vice versa. The resulting class schedule was free of overlaps. This was because the chromatic number obtained in the graph coloring was smaller than the available time slots at SMAN 7 Mataram.

Abstract

Good quality service for refueling fuel oil (BBM) at gas stations was vital for today's society. However, the service quality at gas stations has not been known until now. One of the gas stations that were strategic in Mataram city, namely SPBU 54.832.03 on Jl. Majapahit Pagesangan. One of the factors affecting the quality of gas station services is the availability of the number of dispensers that services customer at the gas station. Therefore, the research of the optimal gas station service's optimal condition was based on the number of dispensers of fuel. We use the distribution of arrival times of customers and service times at the gas stations. On the observation, we use two kinds of fuel dispensers, namely the dispenser of Premium and Pertalite for the motorcycle. The Monte Carlo simulation method shows that the optimal number of dispensers for the SPBU is three nozzles for Premium dispensers and 4 for Pertalite Motorcycle dispensers.

Abstract

This study aimed to improve students’ mathematics learning outcomes through the implementation of the Teams Games Tournament (TGT) cooperative learning model in fourth-grade students at SD Negeri 12 Mataram during the 2024/2025 academic year. The research employed Classroom Action Research (CAR) using the Kemmis and McTaggart model, which consisted of two cycles. Each cycle included four stages: planning, implementation, observation, and reflection. The research subjects consisted of 14 students. Data were collected through pre-tests, post-tests, and observation sheets. The findings revealed that before the implementation of the TGT cooperative learning model, the average student score was 59.1, with only 14.3% of students achieving the Minimum Mastery Criteria (KKM). After the implementation of the TGT model, the average score increased to 83.2, and 92.2% of students successfully achieved the KKM. The improvement indicated that the TGT cooperative learning model effectively enhanced students’ conceptual understanding and participation in mathematics learning. The success of this model was supported by active learning activities that encouraged students to think critically, collaborate, and engage in group discussions. Therefore, the TGT cooperative learning model is recommended as an effective strategy to improve mathematics learning outcomes in elementary schools.

Abstract

Difficult integral problems that cannot be solved analytically often require numerical approaches. PHP (Perl Hypertexr Prepocessor) programming has become one of the tools that can be used to solve numerical problems. This research aims to develop a numerical integration program using the Simpson 3/8 method and Romberg method on polynomial, exponential, and trigonometric functions with PHP programming, as well as to compare the efficiency of both methods based on relative error and execution time. Based on the implementation of the algorithms of both methods in PHP programming, the research results show that the average error for the Simpson 3/8 method and Romberg method are 0,013787% and 0,001356%, respectively. The comparison of errors between these two methods indicates that the Romberg method is 9,89% more accurate than the Simpson 3/8 method. However, in terms of program execution time, the Simpson 3/8 method requires less time compared to the Romberg method. The average execution time for the Simpson 3/8 method and Romberg method are 0,00117 seconds and 1,77811 seconds, respectively, and the comparison of execution time between these two methods shows that the Simpson 3/8 method is shorter than the Romberg method when using the same number of iterations.

Abstract

The low level of students’ understanding of geometric concepts and the lack of contextual teaching materialsmake mathematics learning tend to be abstract and less engaging. In addition, mathematics learning inschools is still rarely connected to local culture that is closely related to students’ daily lives. Learning thatintegrates local culture can create a more meaningful learning experience for students. Ethnomathematicsbasede-modules can visualize geometric concepts through cultural exploration as a learning medium. Thisstudy aimed to describe the development and determine the validity of an ethnomathematics-based geometrye-module integrating Sasak culture through woven fabric exploration for seventh-grade students at SMPN 6Mataram. The research employed a Research and Development (R&D) approach using Thiagarajan’s 4Dmodel, consisting of the define, design, develop, and disseminate stages. Data from material and media expertevaluations were analyzed using Aiken’s V formula. The results indicated that the developed e-module washighly valid, with a media validity score of 0.86, a material validity score of 0.82, and an overall averagevalidity score of 0.84. Therefore, the interactive website-based e-module is theoretically highly valid for useas a supplementary teaching material in mathematics learning.
