Abstract

Cases of the COVID-19 pandemic are gradually decreasing every day in Indonesia, but the impact of the COVID-19 pandemic has greatly affected various sectors, especially the economy and business. Sales transactions have not yet reached the company's target due to weak public purchasing power. The accuracy of customer segmentation analysis and attractive promo voucher offers are needed to increase the opportunity for people's purchasing power for a product. This study aimed to predict the level of customer purchasing power using the random forest and naïve Bayes methods in the case of multi-class data classification at PT. XYZ. The classification is carried out to determine the type of promo voucher suitable to be offered to customers according to the level of customer purchasing power. The data used is historical daily transaction data from January 1, 2022, to December 31, 2022, which is the transition period for the COVID-19 pandemic. Evaluation using the random forest method produces an accuracy of 99.99%, while the naïve Bayes method produces an accuracy of 92.99%. The random forest and naïve Bayes methods can work very well on large data volumes. However, from the comparison results, it can be concluded that the performance of the random forest method is better than the naïve Bayes method in the multi-class classification case in predicting the level of customer purchasing power at PT. XYZ.

Abstract

The Competency-Based National Examination (CBNE) was held in 2019. The quality of schools can be determined based on the results of it. The purpose of the study was to map high schools / MA in Surakarta City based on its scores in 2018/2019. The number of SMA/MA is 33, both public and private. Data analysis using multidimensional scaling based on the characteristics of CBNE scores in the Indonesian, English, Mathematics, Physics, Chemistry, and Biology exam subjects. The results showed that there were four groups. They were mapped based on the level of similarity of CBNE scores with the characteristics in each exam. SMA/MA mapping is expected to help the community in choosing schools based on the competencies to be developed by students. School clustering means that there is educational inequality in the context of learning outcomes. This is influenced by a wide variety of factors. This research is expected to be the first step for further research in improving student learning outcomes.

Abstract

Designing the scheduling of lecture rosters is one of the common problems faced by all universities. The problem that often occurs as a conflict in the lecture schedule. Lecturers who teach courses, students cannot take certain courses because the lecture schedule they are taking conflicts with other lecture schedules. The main problem in this research is the design of lecture schedules which always conflict due to room availability and lecturer teaching hours. As a result, lecture scheduling becomes more complicated. The case study used is the scheduling of lectures for the Mathematics Department, Faculty of Science and Technology, UIN Sumatera Utara, Medan in the even semester of the 2022/2023 academic year. In this research, a bipartition graph will be formed based on the variables used, namely determining the variable index used in the course, teaching lecturer, teaching time, entry time, exit time, classroom, number of credits, semester and color. After that, the Welch Powell Algorithm will be used to solve the scheduling problem of a bipartition graph which is formed by creating nodes, membership matrix and the final result is a tabulation of the colored bipartition graph as the output of the scheduling. This algorithm also uses MATLAB software. From the results obtained, the algorithm provides an effective digital solution in designing lecture roster scheduling which is still done manually. This will help the mathematics department in overcoming the problems mentioned above. The research results will be explained detail in the results and discussion section.

Abstract

Mathematical literacy plays an important role in life. It can be used by humans in solving everyday life problems. However student’s mathematical literacy ability are still very low. Therefore mathematics learning needs to be oriented to enhancing mathematical literacy ability. Mathematics learning will run smoothly if accompanied by good planning. This study aims to develop teaching module based on problem based learning. This research uses Research and Development method with the ADDIE (Analyze, Design, Develop, Implement, Evaluate) stages. In this preliminary research we carry out the analyze and design stages. At the analyze stage the data is processed using a qualitative descriptive approach and it is known that Three Variables Linear Equation System (TVLES) is difficult material for student. This is caused by limited teaching material and learning is not linked to contextual problems. Based on the results of the mathematical literacy test, it is known that student’s mathematical literacy ability are very low, only 6% student are able to reach minimum criteria of 75. So this research can be continued by developing teaching modules based on problem based learning to enhance student’s mathematical literacy ability.

Abstract

The sharia life insurance program has two ways of managing funds, namely involving a savings element and not involving a savings element. Programs that do not involve a savings element do not have a clear division of tabarru’ funds that must be paid participant so it is the company's job to calculate it . In calculating the percentage of tabarru' funds used method Cost of Insurance (COI) . The COI method is method for calculating tabarru’ funds  with using several parameters, namely mortality tables , investment value , management fees and discount factors . In this research, we will discuss how to obtain tabarru' funds using the 2019 Indonesian mortality table and the 2019 Indonesian mortality table with the Gompertz mortality law, Makeham mortality law and De Moivre mortality law. with method Cost of Insurance . Based on the case illustration, the results show that the tabarru' funds that must be paid by participants are directly proportional to the participant's age, management fees and insurance money, but inversely proportional to the investment value. Tabarru' funds will be greater if using the De Moivre mortality table so this can be a consideration for the company while the Makeham mortality table can be a consideration for participants.

Abstract

Mathematical modeling in the world of economics and banking has particular relevance, especially in terms of providing capital for business activities, particularly for Micro, Small, and Medium Enterprises (MSMEs). Currently, banking activities are predominantly dominated by conventional banks that apply interest, which in Islamic Sharia is considered as riba, and it is incumbent upon Muslims to avoid riba and conduct all their affairs in accordance with Islamic Sharia. This research discusses a mathematical model of a profit-loss sharing system in accordance with Islamic Sharia using the profit-loss sharing model scheme, which is one of the investment models in Islamic finance with a musyarakah contract. The data is derived from the daily profit and loss of a micro trader for the period of September 2023 in Cijantung, East Jakarta, which is then generated for periods of 35, 40, and 50 days, following normal, lognormal, and gamma distributions, with an investment capital of Rp 1,500,000, Rp 3,000,000, and Rp 4,500,000, and profit-sharing portions of 2%, 5%, and 7%. This research is capable of demonstrating a profit-sharing scheme and optimization functions in profit distribution, as well as determining parameters that are more advantageous for traders and capital owners compared to the usury model because the imposed penalties are considered burdensome for the public. Generating data following a normal distribution provides a more realistic profit-sharing scheme but a lognormal and gamma distribution yields the largest profit-sharing portion for investor and trader.

Abstract

21st century mathematics education has made use of science and technology while maintaining the philosophy of mathematics from an ethical and epistemological standpoint. This paper examines the goals of the philosophy of mathematics from an epistemological and ethical perspective. It also investigates the relationship between these perspectives and the practice of studying mathematics in the twenty-first century. This article was written using the Publish or Perish software and a systematic literature review approach. 41 initial articles were found by inputting keywords. Following review, fifteen articles were found to be in agreement. This study reveals that the goal of mathematics philosophy is to understand truth, meaning, certainty, and the nature and sources of mathematical knowledge, as well as how to interpret mathematics, from an epistemological perspective. Analyze and reflect on the ethical implications of mathematical practices. Its epistemological application in 21st century learning practices guides the way concepts are positioned, logical arguments are made, and mathematical problems are solved. Next, ethical considerations include maintaining student privacy, establishing learning agreements in every class, and avoiding creating group distinctions. by utilizing an interactive, student-centered learning paradigm like PBL, inquiry, contextual learning, use of technology, STEM, and others. Such behaviors will subsequently cultivate the values of critical, communicative, creative, and cooperative character. Therefore, we must uphold the fundamentals of learning in the 21st century, both in terms of epistemology and ethics.

Abstract

Sulfur dioxide (SO2) pollution is a serious problem that negatively affects air quality and human health. So2 is generated by various human activities, especially the combustion of fossil fuels, as well as from natural sources such as volcanic eruptions. The emission of SO2 in urban areas, including Medan, Indonesia, has raised concerns as it is associated with respiratory diseases and the formation of acid rain. This research aimed to estimate comparative SO2 concentrations in Medan City using geostatistical methods, specifically ordinary kriging and inverse distance weighted (IDW). Air quality monitoring data from the Dinas Lingkungan Hidup Kota Medan were collected during a certain period. The collected data were analyzed and then interpolated using ordinary kriging and IDW methods. Furthermore, the Ordinary Kriging method involves testing the OK assumption, calculation of the experimental semivariogram, calculation of the theoretical semivariogram, structural analysis, and calculation of Root Mean Square Error (RMSE). Meanwhile, the Inverse Distance Weighted method involves calculating the Euclidean distance, determining the weights based on the power parameter, calculating the RMSE value, and estimating the SO2 concentration. The comparison results show that the OK method is more accurate in determining SO2 concentration compared to the IDW method in Medan City. In the estimation of sulfur dioxide (SO2) concentration, the OK method used the best theoretical semivariogram model, namely the exponential model, and in the estimation process of the IDW method, the power parameter 1 was used.
