The policy of studying at home requires students to organize their learning. The ability of students to manage their own learning is also known as self-regulation learning (SRL) ability. Interactive multimedia in learning is expected to help students manage their learning independently. This study aims to describe student’s SRL ability and learning outcomes in mathematics learning with the help of interactive multimedia. It is also to analyze the relationship between SRL and student learning outcomes after learning mathematics with the help of interactive multimedia. This research is descriptive that involved 274 of 7th grader students. Data were collected using tests and questionnaires. The data analysis technique used descriptive statistics and simple linear regression. The results showed that the students' average SRL in the medium category and student learning outcomes were enough. Student self-regulation learning has a positive effect on learning outcomes. Thus, interactive multimedia makes students more independent in learning to increase their self-regulation learning abilities and ultimately improve their learning outcomes. Therefore, to foster students' SRL skills, teachers can use interactive multimedia as an alternative media in learning mathematics.

Economic development is affected by several factors, one of which is the inflation rate. One indicator used to measure the inflation rate is Consumer Price Index (CPI). The CPI data is recorded simultaneously at several locations over time, produces space-time data. In Central Java Province, CPI is calculated in six regency/cities, so the CPI is affected by the time and other locations named space-time effect. The forecasting methods involve space and time effect simultaneously is GSTAR. This study used the GSTAR model to forecasting the CPI in 3 cities in Central Java, assuming that autoregressive and space-time parameters differ for each location. This study aims to obtain the best GSTAR model to forecast the CPI in three cities in Central Java by using the IDW and NCC weighting. The results indicated that the best GSTAR model for forecast the CPI in three cities (Surakarta, Semarang, and Tegal) was the GSTARI (1,1,1) model. The GSTARI (1,1,1) model fulfils the assumption of homoscedasticity, white noise, and multivariate normal. The MAPE values obtained using the IDW and NCC weighting are 0.2922% and 0.2914%, respectively. From these results, it can be concluded that the best GSTARI (1,1,1) model to forecast the CPI data in three cities in Central Java is NCC weights, as they have a minimum MAPE value .

The Decomposition of a Finitely Generated Module over Some Special Ring
Authors: Wardhana I Gede Adhitya Wisnu
Published: June 2023

This research aims to give the decompositions of a finitely generated module over some special ring, such as the principal ideal domain and Dedekind domain. One of the main problems with module theory is to analyze the objects of the module. This research was using a literature study on finitely generated modules topics from scientific journals, especially those related to the module theory. And by selective cases we find a pattern to build a conjecture or a hypothesis, by deductive proof, we prove the conjecture and state it as a theorem. The main result in this study is the decomposition of the finitely generated module is a direct sum of the torsion submodule and torsion-free submodule.  Since the torsion-free module is always a free module over a principal ideal domain, then the torsion-free submodule is a free module. Last, we generalize the ring, from a principal ideal domain, to a Dedekind domain. We found then the torsion-free submodule became a projective module.  Then the decomposition of the finitely generated module is a direct sum of the torsion submodule and the projective submodule. These results should help the researchers to analyze the objects on module theory.

Published: June 2023

The unequal amount of questions that test students' lower and higher-order thinking skills is a concern in mathematics learning evaluation. The unequal amount of questions resulted in poor cognitive levels among students. The purpose of this study is to develop questions that may be used to assess the higher-order thinking skills of senior high school pupils and fulfill the requirements of being valid, practical, and effective. This study is a developmental research that employs the formative evaluation model. Validation sheets, student evaluation sheets, and examinations that measure students' higher-order thinking skills are among the data gathering procedures employed. According to the researchers' findings, the questions generated matched the valid, practical, and effective requirements. The valid criteria are based on the validators' assessments, and both validators agree that the questions created are good and possible to utilize with a few adjustments. Student answer papers to the established questions serve as the basis for practical criteria. According to the response form, 85 percent of pupils answered positively to the questions. Effective criteria are based on pupils' abilities to answer the questions that have been established. According to the test findings, 85 percent of students satisfied the minimal completeness requirements for both questions testing higher-order thinking skills, indicating that the questions were effective. The questions that have been developed by researchers can be used by teachers to evaluate students' higher-order thinking skills so that teachers do not only provide questions that measure students' lower-order thinking skills. In addition, the questions that have been developed can be used as a reference for developing questions that can measure students' higher-order thinking skills.

Published: June 2023

The phenomenon today in schools is that teachers rarely build student arguments but only accept students' answers. However, teacher activities that always make students 'arguments and support each solution and defend students' arguments without long debates are relevant and exciting to study. This study aims to explain and explore the promotion of mathematics teacher reasoning in tasks in the classroom. The author surveyed teachers who teach mathematics at the junior high level. This research is a qualitative descriptive study with an experimental research design, which begins with a survey of teachers who teach mathematics at the junior high school level in Maluku Province. First, the authors conducted initial observations for one month in several junior high schools in Maluku Province with the guide of the observation instrument for the promotion of teacher reasoning in learning. Second, the writer states that there are three groups of attractive teachers who can promote mathematical reasoning in each of their teachings based on indicators of teachers' mathematical reasoning. Third, the writer created the same math problems for the three teachers and observed how they built students' reasoning and evaluated their thinking efficiently. Finally, the results and surveys were carried out by triangulation with direct trials on seven classes at the junior high level. The results show how teacher actions promoting mathematical reasoning give generalizations or justifications. Teacher actions supporting precise rationale are discussed in more detail in this article.

Authors: Nurdiati Sri , Najib Mohamad Khoirun
Published: June 2023

Grade point average (GPA) is initial information for supervisors to characterize their supervised students. One model that can be used to predict a student's study period based on GPA is a machine learning-based regression model so that supervisors can apply the right strategy for their students. Therefore, this study aims to implement and select a machine learning-based regression model to predict a student's study period based on GPA in semesters 1-6. Several regression models used are least-square regression, ridge regression, Huber regression, quantile regression, and quantile regression with l_2-regularization provided by Machine Learning in Julia (MLJ). The model is evaluated and selected based on several criteria such as maximum error, RMSE, and MAPE. The results showed that the least-square regression model gave the worst evaluation results, although the calculation method was easy and fast. Meanwhile, the quantile regression model provided the best evaluation results. The quantile regression model without regularization gives the smallest RMSE (2.31 months) and MAPE (3.56%), while the quantile regression model with l_2-regularization has a better maximum error (4.9 months). The resulting model can be used by supervisors to predict the study period of their supervised students so that supervisors can characterize their students and can design appropriate strategies. Thus, the student's study period is expected to be accelerated with a high-quality final project.

Published: June 2023

The background of this research is to produce and develop cube and cuboid material e-module products centred on regional culture. The teaching materials are still printed books containing material and questions without any complex mathematical concepts, so there is a lack of linking regional culture with mathematics. That affects the lack of understanding of students' ethnomathematics during the geometry material pandemic. This study aims to develop an e-module cube and cuboid based on ethnomathematics for fifth-grade elementary school students. Research development methods with 4D include definition, design, development and deployment. The data was analyzed using quantitative and qualitative data analysis techniques through media and material expert validators and teacher and student response questionnaires. The results showed that the e-module cube and cuboid based on ethnomathematics were declared feasible or valid with an average score of 82.5%. They used e-modules through teacher and student response questionnaires and obtained an average score of 85%, which was stated to be very practical. Therefore, it affects students' cognitive understanding of cube and cuboid material with an average value of 84.1. The ethnomathematics-based e-module cube and cuboid can help students improve their contextual abilities.

This article discusses the results of research on the combination of learning rate values, momentum, and the number of neurons in the hidden layer of the ANN Backpropagation (ANN-BP) architecture using meta-analysis. This study aims to find out the most recommended values at each learning rate and momentum interval, namely [0.1], as well as the number of neurons in the hidden layer used during the data training process. We conducted a meta-analysis of the use of learning rate, momentum, and number of neurons in the hidden layer of ANN-BP. The eligibility data criteria of 63 data include a learning rate of 44 complete data, the momentum of 30 complete data, and the number of neurons in the hidden layer of 45 complete data. The results of the data analysis showed that the learning rate value was recommended at intervals of 0.1-0.2 with a RE model value of 0.938 (very high), the momentum at intervals of 0.7-0.9 with RE model values of 0.925 (very high), and the number of neurons in the input layer that was smaller than the number of neurons in the hidden layer with a RE model value of 0.932 (very high). This recommendation is obtained from the results of data analysis using JASP by looking at the effect size of the accuracy level of research sample data.
Frieze Group in Generating Traditional Cloth Motifs of the East Nusa Tenggara Province
Authors: Nataliani Yessica
Published: June 2023

Ethnomathematics studies the relationship between mathematics and culture. Indonesia has many traditional cultures. One of them is traditional cloth. The traditional cloth from East Nusa Tenggara (NTT) province is called tenun ikat. Since the motif of tenun ikat consists of symmetrical and repeated patterns, it can be generated using Frieze groups. The Frieze groups are the plane symmetry groups of patterns whose subgroups of translations are isomorphic to Z. There are seven groups in the Frieze groups, i.e., F_1, F_2, F_3, F_4, F_5, F_6, and F_7. Translation, reflection, rotation, and glide reflection are the transformation used in the Frieze groups. In this paper, Frieze groups are used to generate digital tenun ikat motifs from the basic pattern. Since one piece of original tenun ikat may consist of some basic patterns, the basic patterns are identified first, and then each of them is generated into the desired pattern, according to the suitable Frieze groups. Furthermore, a GUI Matlab program is developed to generate the Frieze groups. Three motifs of tenun ikat are presented to demonstrate the implementation of Frieze groups. With the Frieze group, users can generate other patterns from a basic pattern, so users can generate new motifs of tenun ikat without leaving the cultural characteristics of NTT province.

Published: June 2023

Technological advances during the COVID-19 pandemic in Indonesia gave rise to the PeduliLindungi application which is developed by the government to prevent the spread of COVID-19. The advantages and disadvantages of developing PeduliLindungi can be seen from the responses and opinions from users, one of which is through the Twitter. A person's opinion about PeduliLindungi based on the tweet can be classified into positive, negative, or neutral categories using a Machine Learning approach with the Support Vector Machine (SVM) algorithm. In this paper, multiobjective optimization modeling is used to maximize the performance metrics, which are the value of Accuracy, Precision, Recall, and F1-Score. The value of the performance metrics is considered to contain uncertainty factors. Therefore, the optimization problem is solved by using Robust Optimization to handle the uncertainty factor. The data uncertainty is assumed to be belongs to polyhedral uncertainty set thus the resulted robust is computationally tractable. Numerical experiment is presented to complete the discussion.

Mathematical Modeling of Foot and Mouth Disease Spread on Livestock using Saturated Incidence Rate
Authors: Fahcruddin Imam , Harianto Joko , Fitrial Denny
Published: June 2023

Foot and Mouth Disease (FMD) is an acute infectious disease that attacks livestock, thus threatening the availability of food and the husbandry industry. This paper discusses the formulation of a mathematical model for the spread of FMD in livestock with a saturated incidence rate. The research method used is quantitative mathematical modeling with simulation, with stages including problem identification, determining assumptions, model formulation, analysis and model simulation. The discussion results obtained two equilibrium points, namely the non-endemic equilibrium point and the endemic equilibrium point, and then analyzed for stability. Numerical simulation is presented using Runge-Kutta approximation with MATLAB. Furthermore, after a sensitivity analysis, the parameters that greatly influenced the spread of FMD were direct or indirect contact (which led to the entry of the FMD virus) and the supporting capacity of livestock. Then the most influential parameter in reducing the spread of FMD is the application of culling on exposed animals and infected animals. The FMD modeling is a form of mathematical application to simulate the spread of disease on livestock.

Authors: Mussafi Noor Saif Muhammad
Published: June 2023

The short interval between the collecting and distribution of zakat al-fitr is a recurring issue. As a result, ‘amil does not always pay attention to the ideal route, leading in inefficient transportation expenditures. This study aims to minimize the amount of vehicle mileage that affects fuel consumption. The branch-and-bound algorithm was employed to overcome the distribution route optimization problem by proposing the shortest circuit that traverses each district exactly once and returns to its original district. The procedures involve data collecting, graph analysis, branch-and-bound analysis, MATLAB code development, and the recommendation of the best route. The results indicate that the branch-and-bound algorithm can numerically solve the distribution route optimization corresponding to traveling salesman problem. Furthermore, according to a case study of zakat al-fitr distribution conducted by Eradication of Illiteracy Al Quran (PBHA), the total optimal distance of the computational-based algorithm was 152.9 km, with inter-village routes starting from Sidorejo and then via Sumberarum, Pendoworejo, Gerbosari, Banjaroyo, Banjarasri, Sendangagung, Tuksono, Argodadi, Triwidadi, Jatimulyo, Giripurwo, and ends in Sidorejo.
The Compound Area of Quadrilaterals and Triangles: A Worked Example Based Learning Design
Authors: Retnowati Endah , Fadlila Nindy
Published: June 2023

Complex yet hierarchical mathematical material in fact does not mean that the process of schema acquisition and accommodation in long-term memory is easy. For an instance, year seven students learn to solve problems related to the compound area of quadrilaterals and triangles. This problem may be categorized as a well-structured problem, therefore, it might be procedurally obvious to reach the solution, for those who have possessed sufficient prior knowledge of the aspects of the shapes. This study aims to discuss instructional strategy for novices when learning to solve problems like these. Based on a cognitive load theory, the strategy of worked example could be applied effectively for novices. The design of the worked example must be presented in such a way it could minimize extraneous cognitive load. The composite shapes of quadrilateral and triangles might be challenging to be described in an integrated format to avoid the split attention effect. This paper shows how this can be done by using techniques, such as (1) number sequences of the solution steps; (2) different colors for prompting attention resource; (3) less wording, more procedure application; and (4) consistency of layout within overall material. In order to apply these, the instructional designers should follow ADD steps, (1) Analyze the learning content, arrange them accordingly; (2) Design one worked example, evaluate its accuracy and niche; and (3) Develop into several worked example pairs. Two worked example with paired problems have been successfully developed and declare valid. Eventually, it might be suggested that comprehensive consideration when designing worked example that contain pictures should reflects how students use their cognitive resource during learning.

Graphs that have the properties of odd harmonious labeling are odd harmonious graphs. The research objective of this paper is to obtain odd harmonious labeling on layered graph C(x,y) and layered graph D(x,y). The research used in this paper is a qualitative method. The research flow consists of data collection, processing, and analysis. The data collection stage consists of constructing the definition of the new class graph, the data processing stage consists of constructing the vertex labeling and edge labeling, and the data analysis stage consists of constructing the theorem and proving it. The research results show that the layered graph C(x,y) and layered graph D(x,y) fulfill odd harmonious labeling. Such that the layered graph C(x,y) and layered graph D(x,y) are odd harmonious graphs. The benefit of this research is to add new properties of odd harmonious graphs. In addition, it does not rule out the possibility that this research can be developed again both in theory and application.

Algebra is one of the mathematics materials in junior high school which is synonymous with symbols. There is a concept to assess students' sensitivity to symbols, namely symbol sense. One of the skills that must be possessed by students is thinking skills. The purpose of this study is to describe the thinking process of junior high school students from the symbol sense task. This is qualitative research. The steps in this research is (1) making instruments; (2) selecting subjects; (3) collecting data; and (4) analyzing data.The subjects in the study consisted of four ninth-grade students who had good math and communication skills. Data collection was carried out by giving symbols of sense assignments and followed by task-based interviews. The collected data was then analyzed using the stages of data collection, data condensation, data display, and drawing conclusions. The results showed that all subjects showed good thinking skills. It's just that a student is not good at drawing conclusions because he does not check the answers independently. For the ability of the sense of symbol students lack achievement in two characteristics of the symbol sense. Only two people demonstrated the "friendliness with symbol" characteristic well. This research only examines students' symbol sense thinking on two of the six characteristics of symbol sense. Other researchers can conduct research on the six characteristics of sense symbols thinking.

Graph theory can give a representation of abstract mathematical systems such as groups or rings. We have many graph representations for a group, in this study we use the coprime graph representation for a generalized quaternion group to find the numerical invariants of the graph, which are the clique number and the chromatic number. The main results obtained from this study are the clique number of the coprime graph representation for the generalized quaternion group is equal to the chromatic number of the coprime graph representation for the generalized quaternion group for each case of  the order.

The purpose of this study was to determine the effectiveness of the implementation of TPACK in microteaching mathematics education students in terms of differences in online learning platforms. The type of research used in this study is Mixed Method with a Sequential Explanatory design by starting with quantitative data collection and then continuing with qualitative data collection.. The subjects in this study consisted of 12 mathematics students. Subjects were given a TPACK ability test and the opportunity to simulate learning using an online learning platform, then conducted in-depth interviews regarding the implementation results. The results showed that there were differences in the ability to implement student TPACK in microteaching consisting of PCK components including basic skills of explaining and asking, TPK components covering basic skills of explaining and providing reinforcement, TCK components covering basic skills of explaining and providing variations, and TPACK components covering basic skills of opening and closing as well as essential skills of managing small groups. Based on the two platforms used, Moodle is better when compared to Google Classroom in supporting and making it easier for students to implement TPACK when compared to using Google Classroom. Especially in terms of appearance, features, integration with other applications, and storage limits. It can be stated that Moodle is more effective when compared to Google Classroom in implementing TPACK in microteaching.

Abstrak: Penelitian ini berfokus pada bagaimana strategi yang digunakan oleh mahasiswa perguruan tinggi yang tinggal di daerah terpencil berhasil bertahan untuk mengikuti perkuliahan dengan baik. Untuk melakukan penelitian ini menggunakan metode kualitatif. Salah satu teknik yang digunakan dalam metode kualitatif adalah wawancara (wawancara terpandu-virtual). Wawancara ini dilakukan untuk menggali lebih dalam informasi yang berkaitan dengan strategi pembelajaran yang dilakukan oleh siswa (partisipan). Studi ini melaporkan dampak pembelajaran online, seperti koneksi internet yang tidak memadai, sarana dan prasarana yang terbatas, serta biaya yang harus dikeluarkan untuk membeli data internet yang mahal. Penelitian ini menekankan pada pentingnya mengembangkan strategi pembelajaran dan memperhatikan orang-orang yang paling dekat dengan siswa agar proses pembelajaran berjalan dengan baik dan mengatasi kendala akibat pandemi COVID-19.Abstract: This study focused on how the strategies used by students of higher education who live in remote areas successfully survive to follow the lectures well. To do this research, we use qualitative method. One of the techniques used in the qualitative method is interview (guided-virtual interview). This interview is conducted to dig deeper through information relating to the learning strategies undertaken by the students (participants). This study reports the impacts of online learning, such as inadequate internet connections, limited facilities and infrastructures, and the costs that must be paid to buy an expensive internet data. This study emphasizes the importance of developing learning strategies and having the attention of those who are closest to the students so that the learning process runs well and overcome obstacles due to COVID-19 pandemic.

Abstrak: Penyakit yang disebabkan oleh virus corona19 menjadi problem besar sehingga mengganggu aspek kehidupan social masyarakat di seluruh Indonesia, hal ini berdampak pada kesehatan masyarakat Indonesia yang sangat mengkhawatirkan, terhambatnya proses disemua bidang seperti ekonomi, pendidikan, dan pelayanan public. Sistem belajar yang selama ini berada di kampus, sekolah dihentikan dan diganti dengan sistem belajar daring untuk mengurangi keramaian sehingga tercapai tujuan dalam pembatasan penyebaran virus. Di Universitas Borneo Tarakan sendiri telah melakukan kebijakan belajar dari rumah selama beberapa bulan terakhir, namun khusus mahasiswa keperawatan yang akan melakukan praktik klinik maka wajib melakukan praktik terlebih dahulu di laboratorium keperawatan dengan aturan-aturan yang telah di tetapkan, salah satunya adalah menjalankan aturan protocol kesehatan Covid-19 dalam melaksanakan praktikum keperawatan. Tujuan penelitian ini adalah mengetahui tingkat kepatuhan mahasiswa keperawatan UBT dalam menjalankan protocol kesehatan covid-19 selama proses laboratorium. Penelitian ini menggunakan metode cross-sectional dan studi observasional dengan teknik purposive sampling. Didapatkan hasil nilai p value kurang dari 0,05 yaitu 0,000 yang artinya terdapat hubungan antara penerapan protokol kesehatan dengan tingkat kepatuhan mahasiswa dalam menjalankan praktikum di laboratorium  selama pandemi Covid-19.Abstract:  The corona virus 19 is a big problem that disrupts aspects of social life throughout Indonesia, this has an impact on the health of the Indonesian people, hampering processes in all fields such as the economy, education, and public services. The learning system that had been on campus, schools was stopped and replaced with an online learning system to reduce the spread of the virus. At the University of Borneo Tarakan itself has implemented a study from home policy for the past few months, but specifically for nursing students who will carry out clinical practice, they are required to practice first in a nursing laboratory with established rules, one of which is implementing the Covid-19 health protocol rules. in carrying out nursing practice. The purpose of this study was to determine the level of compliance of UBT nursing students in carrying out the Covid-19 health protocol during the laboratory process. Cross-sectional method and observational study using purposive sampling technique. The p-value is less than 0.05, which is 0.000, which means that there is a relationship between the application of health protocols and the level of student compliance in carrying out laboratory practicums during the Covid-19 pandemic.
