A well-constructed concept can aid pupils in comprehending any learning content. However, as seen by how students solve math problems, the construction process frequently encounters flaws. Students make various conceptual construction errors in online learning. This is a qualitative study conducted on Mathematics Education students of Universitas Papua. The purpose of this study was to determine the errors made by students in constructing concepts of functions during online learning. Five subjects were selected as the subjects. They were chosen by using the purposive sampling technique. The instrument was developed using material from online lectures on functions and has been validated by experts in the field of mathematics education. The findings indicated that there were five misconstruction concepts, i.e. pseudo construction, construction holes, mis-logical construction, mis-analogical construction, and misconstruction in problem-solving. For further research, to avoid unnecessary construction errors, it is recommended that before the learning process is carried out, the teacher should know the construction of students’ concepts, so that the process of students’ conceptual change in online learning can be known.

The purpose of this studi is to find an expectations and variability as estimators of the risk of earthquakes occurring in each province in Indonesia. Indonesia is a country that prone to natural disasters, especially earthquakes and tsunamis. The earthquake disaster damage the buildings and casualties. The risk of loss from earthquakes can be transferred using insurance. Insurance companies certainly need an analysis to estimate the probability of an earthquake occurring at a certain location and time. Hazard rate has an important role in the prediction theory of the process of earthquakes. The hazard rate can be known by the single decrement method. After the hazard rate is known, the survival function and the distribution function of the cumulative distribution of earthquake data in Indonesia will be known to look for expectations and variability as estimators of the risk of earthquakes occurring in each province in Indonesia. The data used in this study is earthquake that happen in Indonesia categorized as destructive earthquake minimum 5 magnitude. We used the data to compare a hazard function using linear model, quadratic model, cubic model and exponential. First, we plot and then using each models find the standard error. The best model suggest for Indonesia prediction Time of Earthquake Occurrence using an exponential model.

Published: June 2023

Mathematics is a vital means needed by students to solve various problems, both personal and social, and it is required to succeed in work. Thus, students are highly expected to possess good mathematical literacy. In the 21st Century, most of parents would rather choose pesantren-based schools for their children since they believe that theirs will have chance to acquire universal and religious sciences, at once, for their life. Further, the current research was aimed to investigate level of algebraic literacy among pesantren-based senior high school students, along with its determinant factors. Qualitative research method was employed by means of descriptive approach. Moreover, there were 30 students involved in the research; all of which were the twelfth graders of Science Class of a pesantren-based senior high school in Madura, Indonesia. To collect data, two instruments were used: algebraic literacy test and guideline to interview with the Math teacher and the Vice Principal of Curriculum Affairs. The results showed that level of algebraic literacy among students was dramatically low, with 94% of whom classified in below Level 1, 3% in Level 2, and 3% in Level 3. Moreover, lack of student’s focus in learning Mathematics was one of possible causes of it as the students were strongly demanded to learn about two major sciences at once. Therefore, any endeavors for betterment from the teacher and institution are needed to make algebraic literacy among students get improved; one of which can be by integrating pesantren and national education curricula.
Fuzzy Support Vector Machine Using Function Linear Membership and Exponential with Mahanalobis Distance
Authors: Sukeiti Wiwi Widia , Surono Sugiyarto
Published: June 2023

Support vector machine (SVM) is one of effective biner classification technic with structural risk minimization (SRM) principle. SVM method is known as one of successful method in classification technic. But the real-life data problem lies in the occurrence of noise and outlier. Noise will create confusion for the SVM when the data is being processed. On this research, SVM is being developed by adding its fuzzy membership function to lessen the noise and outlier effect in data when trying to figure out the hyperplane solution. Distance calculation is also being considered while determining fuzzy value because it is a basic thing in determining the proximity between data elements, which in general is built depending on the distance between the point into the real class mass center. Fuzzy support vector machine (FSVM) uses Mahalanobis distances with the goal of finding the best hyperplane by separating data between defined classes. The data used will be going over trial for several dividing partition percentage transforming into training set and testing set. Although theoretically FSVM is able to overcome noise and outliers, the results show that the accuracy of FSVM, namely 0.017170689 and 0.018668421, is lower than the accuracy of the classical SVM method, which is 0.018838348. The existence of fuzzy membership function is extremely influential in deciding the best hyperplane. Based on that, determining the correct fuzzy membership is critical in FSVM problem.

Published: June 2023

Digital skills for the twenty-first century are comprise of four fundamental capabilities: cognition abilities; process capabilities; systems capabilities; and social skills. Using one's ability to think creatively to demonstrate cognitive abilities can be very effective. On the other hand, critical thinking is a skill that can be developed at the university level and is used to transform raw data into meaningful information. Furthermore, the study purpose is investigate the relationship the entrepreneurial skills in students in the world of education, both in terms of educational and economic issues. Researchers are looking into the relative importance of creative thinking (CRE), critical thinking (CRI), and entrepreneurial skills (ETS) as primary predictors of success when it comes to learning and mastering skills in the technologically advanced development society (TCDS). In this study, which takes a quantitative approach, a cross-sectional survey gathers data. In order to analyze the relationship formed by CRE, CRI, and ETS among university students in TCDS, we used the structural equation model (SEM) method. In this study, 85 students from the Faculty of Teacher Training and Education, and 315 students from the Faculty of Economics and Business at Universitas Muhammadiyah Purwokerto participated, for a total of 315 students. The following research procedures were used in this investigation: (3) The relationship between CRE, CRI, and ETS was determined using a Structural Equation Model (SEM). In addition, the findings of this study include the following points: The EFA and CFA analysis revealed that the CRE construct contained four valid sub-constructs, while the CRI and ETS constructs each contained five valid sub-constructs. The results of the SEM analysis revealed a statistically significant relationship between CRE, CRI, and ETS, with a moderately significant relationship between CRE and ETS ( = 0,291), as well as a statistically significant relationship between CRI and ETS ( = 0,143). The correlation between CRE and CRI, on the other hand, was found to be high ( = 0.894). Finally, demonstrate that the CRE, CRI, and ETS have played a role in improving the performance of university students during the TCDS era.

Published: June 2023

This study aims to identify the possibility of learning obstacles in the concept of Geometric Transformation based on the meaning of the Geometric Transformation concept that students have regarding their experience in obtaining the definition of the Geometric Transformation concept. This study uses a qualitative method and Didactical Design Research for methodological framework that contains three stages of analysis: prospective, metapedadidactic, and retrospective. Teachers who will carry out the learning reflection process based on didactical design research were chosen through purposive sampling as research participants. Forty-eight students took the written test, and then six students were selected by purposive sampling to participate in in-depth interviews. Data analysis was carried out descriptively by reducing data, presenting data, and drawing conclusions. The result indicates that the meaning of the concept of Geometry Transformation, according to students, was the mapping of points in a plane to a set of points in the same plane; the existence of inconsistencies and ambiguity of meaning, and the emergence of the findings of other meaning units of Geometric Transformation concepts. The experience of student meaning shows a tendency for students to get a sense from what is taught by teachers and books with more procedurally oriented concept meanings. Based on the purpose and experience of students' definition, there are learning obstacles in the Geometric Transformation concept, including ontogenic obstacles, epistemological obstacles, and didactical obstacles. These learning obstacles can be a valuable consideration for improving and developing learning designs related to the concept of Geometric Transformation.

Authors: Silalahi Bib Paruhum , Sahara Farahdila , Hanum Farida , Mayyani Hidayatul
Published: June 2023

Travelling Salesman Problem (TSP) is a problem where a person must visit some places, starting from one city and then moving on to the next city with the conditions that the places visited can only be passed precisely once and then back to the starting city. TSP is an NP-hard, an important problem in operations research. TSP problems can be solved by an exact method or an approximation method, namely the metaheuristic method. This research aims to solve the TSP problem with an approximation method called the Simulated Annealing (SA), and then compare the results of this approximation method with the exact Branch and Bound method. The results indicated that the SA method could accomplish TSP problems. However, like other metaheuristic methods, SA only accomplishes it using an approach to get good results. Still, it cannot be determined that SA has the most optimal results, but the time needed by the SA method is faster than the Branch and Bound method. In case I, the percentage difference between the distance generated using the SA method with the B-and-B method is 0%, in case II it is 7% and in case III it is 8%.

Multi-objective integer optimization model that contain uncertain parameter can be handled using the Adjustable Robust Counterpart (ARC) methodology with Polyhedral Uncertainty Set. The ARC method has two stages of completion, so completing the second stage can be assisted by the Benders Decomposition. This paper discusses the systematic review on this topic using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). PRISMA presents a database mining algorithm for previous articles and related topics sourced from Scopus, Science Direct, Dimensions, and Google Scholar. Four stages of the algorithm are used, namely Identification, Screening, Eligibility, and Included. In the Eligibility stage, 16 articles obtained and called Dataset 1, used for bibliometric mapping and evolutionary analysis. Moreover, in the Included stage, six final databases obtained and called Dataset 2, which was used to analyze research gaps and novelty. The analysis was carried out on two datasets, assisted by the output visualisation using RStudio software with the " bibliometrix" package, then we use the command 'biblioshiny()' to create a link to the “shiny web interface”. At the final stage of the article using six articles analysis, it is concluded that there is no research on the ARC multi-objective integer optimization model with Polyhedral Uncertainty Sets using the Benders Decomposition Method, which focuses on discussing the general model and its mathematical analysis. Moreover, this research topic is open and becomes the primary references for further research in connection.

This study intended to investigate the creative thinking dispositions of students who can perform truth-seeking in solving mathematical problems. Truth-seeking behavior tends to show students' thinking disposition when they need to solve math problems. This behavior is very much needed by students in solving math problems, especially HOTS-type questions. This study is qualitative and employs a phenomenological approach. Three students from the Integrated Islamic Junior High School in Manokwari who sought the truth served as research subjects. Their answers on the answer sheets encouraged the determination of the subjects’ tendencies in truth-seeking and creative thinking. The results of thought-based and task-based interviews were then incorporated into the analysis to determine the creative thinking dispositions of truth-seeking students and the relationship between truth-seeking and creative thinking dispositions. The findings of this study indicate that all research subjects have diverse creative thinking dispositions; the more truth-seeker indicators that are met, the more creative thinking dispositions they possess. When solving mathematical problems, students tend to show how they think by how hard they try to find the truth. This result implies that it needs more research on the level of creative thinking disposition and how to increase students' true search.

The purpose of this study is to determine and analyze the effect of own-source revenue and transfer revenue on capital expenditure in South Tangerang City. The data used is time series data regarding local own-source revenue and transfer revenue on capital expenditure in South Tangerang City 2012-2021. Data analysis methods include Multiple Regression Analysis, t test, and coefficient of determination analysis. From the Multiple Regression Analysis, the regression equation Y=1.03819 + 0.521X2-0.612X3 is obtained. The constant of 1.03819 means that the increase in capital expenditure allocation is 1.03819 percent if there is no increase in local revenue and transfer revenue. The regression coefficient of the local own-source revenue variable shows a positive influence on capital expenditure of 0.521. From the t-test results, it can be explained that local own-source revenue has a significant effect on capital expenditure, where the t-count> t-table value is obtained (2.701> 2.306). The regression coefficient of the local own-source revenue variable shows a negative effect on capital expenditure of 0.612. From the t-test results, it can be explained that transfer revenues have a significant effect on capital expenditures in South Tangerang City, where the t-count value is obtained < t-table (1.259 < 2.306). From the coefficient of determination analysis, it is known that local revenue and transfer revenue affect capital expenditure by 47.4%, while the remaining 52.6% is influenced by other variables outside this research model. Increased capital expenditure has an important role because it has a long-term benefit period to provide services to the public because infrastructure development and the provision of various facilities are carried out to increase investment attractiveness. Industrial infrastructure development has a real impact on the increase in local revenue. So that if the Regional Government wants to improve public services and people's welfare by increasing capital expenditure, then the Regional Government must strive to explore as much local revenue as possible.

The Hatam tribe is one of the sub-tribes of the Arfak tribe. This study aims to explore the numeracy culture of the Hatam Tribe spoken by the Hatam Tribe community who inhabit Nuhuwei Village, Ransiki District. This research is ethnographic. The techniques used for data collection are interviews, exploration, literature study, desk study, and documentation. Interviews and explorations were conducted with several elders who spoke the Hatam language in Nuhuwei Village. Literature and documentation studies were conducted by looking for other sources of information related to the previously existing Hatam language to obtain accurate results. The Desk Study was conducted to find out the mathematical patterns of the Hatam Tribe. The results obtained from this study are that mathematically, the counting patterns spoken by the Hatam people who inhabit Nuhuwei Village have different dialects from the speech of the Hatam people who inhabit other areas. Besides that, another finding is that the pattern of mentioning numbers spoken by the Hatam tribe inhabiting Nuhuwei Village correlates with the counting pattern on the Jarimatika. We call this latest finding related to counting using the Hatam language-based Jarimatika as Himatam (Calculating Using Jarimatika in the Hatam language). This finding shows that learning numeracy for elementary students in Nuhuwei Village can be done more easily using the Himatam Method.
Fuzzy Inference System Tsukamoto–Decision Tree C 4.5 in Predicting the Amount of Roof Tile Production in Kebumen

Tile is a product that is in great demand by many people. This has become a trigger for producers to improve their management. The company's tile production management is still experiencing problems, namely frequent miscalculations in determining the agreement that must be issued in making tile production from customer requests. One of the efforts made is to predict the production that can be done to get the optimal amount obtained, to get a big profit. In this study, to obtain a prediction of the amount of tile production, computerized calculations were carried out using the Tsukamoto fuzzy logic method. This method uses the concept of rules from the C 4.5 decision tree in the building to make it easier to determine the rules that are built without having to consult an expert because C 4.5 will study existing datasets to serve as a reference in forming these rules according to conditions that often occur. The modeling results produce relevant rules after being compared with the actual results. The results of the comparison of predictions with actual production have an error percentage of 29.34%, with a truth of 70.66% (based on the calculation of the Average Forecasting Error Rate (AFER)). Therefore when implemented in the Tsukamoto Fuzzy Inference System it can produce predictions of tile production that are quite optimum. It is said to be quite optimum because all customer requests are met, either generated by the production prediction itself or the prediction results are added up with inventory data, and all predictions are close to actual production.
