Abstract

Petri net is one model representing transitions and places connected by arrows. Max Plus Algebra is an algebraic structure in which all sets of real numbers  are equipped with max (maximum) and (addition). This research created a Petri net model of the customer service system for Bank BRI and a Max Plus Algebra model related to time to minimize service time at Bank BRI. The result is periodic time or characteristic values and vector characteristics where the values and are . The value of this vector's characteristics becomes a periodic time, which only takes 2 days 3 hours during working hours to disburse money after the client's arrival.

Abstract

This study aims to determine the factors that most influence the rate of recovery of pulmonary tuberculosis patients using the Cox Proportional Hazard model. In the case of the cure rate of pulmonary tuberculosis patients, not all independent variables meet the proportional hazard assumption, so the stratified cox regression model is used. The stratified cox regression model used is the stratified cox model with interaction and without interaction involving pulmonary tuberculosis patients in one of the Gorontalo Hospitals. The results showed that the variables of shortness of breath, previous pulmonary tuberculosis patients, and smoking habits were the most significant factors affecting the recovery rate of pulmonary tuberculosis patients.

Abstract

Forecasting the inflation rate is important because the results obtained are used as an indicator that can influence the policies that will be made later. One policy that uses the results of this forecasting as one of the things that can influence it is economic policy and monetary policy. In this study, the method used is the general regression neural network (GRNN). This forecast is applied to inflation data in Gorontalo Province from January 2008 to April 2023, with the conclusion that it produces an inflation forecast for May – December 2023 with a MAPE value of 3.24% or an accuracy rate of 96.76%.

Abstract

Learning mathematics requires students to understand concepts, the low understanding of students' concepts becomes an obstacle in learning. So that the researchers used the background to apply the Index Card Match (ICM) learning model. This study aims to improve understanding of mathematical concepts using the Index Card Match (ICM) learning model on arithmetic sequences and series material. This research is a classroom action research. The research subjects were students of class XI TKJ SMK Negeri 1 Batudaa for the academic year 2022/2023 with a total of 28 students. The techniques used in data collection are observation and tests. The data analysis technique in this study is the analysis of observation of teacher activities, student activities and tests of understanding mathematical concepts. The design used in this study is the research design of the Kammis and Mc Taggart models. The research procedure includes planning, implementation, observation and reflection. The study consisted of 2 cycles. The results showed that the implementation of learning using the Index Card Match learning model on arithmetic sequences and series materials could improve students' understanding of mathematical concepts. This is evidenced by the average results of the mathematical concept understanding test in the first cycle which is 63.57, increasing in the second cycle to 81.42 with the percentage of observations of teacher activities in the first cycle reaching 71.15% while the second cycle reaches 86.53% and the percentage the results of the observation of student activity in the first cycle reached 65.17%, an increase in the second cycle reached 83.92%. Based on the research above, there are benefits in applying the Index Card Match (ICM) learning model, namely, in order to increase understanding of mathematical concepts and foster motivation and interest in learning mathematics.

Abstract

This research is motivated by the low motivation to learn mathematics in mathematics in class VII-3 of SMP Negeri 1 Telaga Jaya. This study aims to increase students' motivation to learn mathematics through the use of cooperative learning models of the Teams Games Tournament (TGT) type. This type of research is classroom action research (PTK). Kemmis and Mc Design. Taggart was used for this research. This study used data collection techniques, namely observation and questionnaires. Teacher observation sheets, student observation sheets, and learning motivation questionnaires were used to view the data. Plan, report, observe, and think about what you have learned are all part of the research process. The research was conducted in two parts. The results showed that teacher activity in learning increased by 88.88%, and student activity increased by 93.75%. Student motivation also increased, with 10 students getting a score of 34.38% in the "very high" category and 65.52% in the "high" category. Indicators show that each student's learning motivation experienced a high increase, with a score of 34.38% in the "very high" category and 65.52% in the "high" category.

Abstract

This article discusses the effect of the project-based learning model on student mathematics learning outcomes in cube and block material with the aim of knowing the differences in student learning outcomes taught using project-based learning models and learning outcomes using direct learning models on cube and block material. The method used is the experimental method with the Posttest only control group design design. The sampling technique uses simple random sampling, and the data collection technique is by administering a learning achievement test in the form of an essay. The results showed that there were differences in the learning outcomes of students who were taught using the project-based learning model and the learning outcomes of students who were taught using the direct learning model where the learning outcomes of students who were taught using the project-based learning model were higher than the learning outcomes of students who were taught using direct learning models on cube and block material. Project-based learning can increase student activity and student motivation in learning that aims to provide an understanding of critical, creative and innovative thinking.

Abstract

This study aims to describe the skills of teachers in implementing variations in the teaching of curved surface solid geometry. The discussion of the curved surface solid focuses on the topic of spheres with the students of SMP Negeri 1 Paguyaman as the research subjects. Research data was obtained through observation of the teaching process and questionnaires. This study employed a descriptive research method to describe the use of variations in mathematics teaching. The study was conducted in class IX of SMP Negeri 1 Paguyaman. The research subjects were 27 ninth-grade SMP Negeri 1 Paguyaman students, consisting of 17 female and 10 male students. Data analysis was performed using quantitative descriptive analysis techniques. The results show that the use of variations in the teaching of mathematics on curved surface solids of spheres reached the "very good" category, with indicators: teacher’s ability to implement variations in teaching at 84%, student activity during the lessons at 84%, and positive student responses to the use of teaching variations at 86%.

Abstract

Higher education in Australia and the UK has undergone significant transformation in recent decades, facing challenges of inclusion, representation and efficiency. In Australia, significant changes have occurred in higher education funding, moving to a more flexible and performance-based model, while the UK still struggles with issues of elitism and social inequality. Both countries face challenges in learning mathematics related to infrastructure and understanding complex concepts. However, both offer strong learning experiences that are relevant to industry needs. This research aims to compare the two countries' higher education systems and analyze the factors that influence the quality of their education, using a descriptive method with diverse data sources such as official reports, academic research and statistical data. The results show that Australia has successfully improved accessibility and equity through diversification and scholarship programs, while the UK still faces major challenges in inclusion and representation. The findings offer important insights into how both countries face the challenges of higher education and seek to develop more inclusive and efficient systems. This research can serve as a reference for governments and educational institutions in developing more effective education policies, capitalizing on Australia's success in diversification and accessibility, and overcoming the obstacles faced by the UK in its efforts to achieve inclusion and social equity in higher education.
