Abstract

Penelitian ini bertujuan mengidentifikasi bukti-bukti yang dihasilkan mahasiswa dalam memecahkan soal-soal Pengantar Analisis Riil, khususnya bukti yang memanfaatkan contoh spesifik. Pendekatan yang digunakan adalah kualitatif. Subyek diambil dari 54 mahasiswa yang menempuh mata kuliah Pengantar Analisis Riil. Seluruh subjek dihadapkan pada dua soal pembuktian. Dari 54 mahasiswa, tidak lebih dari 15% yang mampu menuliskan bukti yang valid. Sekitar 30% masih belum memiliki pengetahuan yang cukup untuk dapat dirangkai menjadi sebuah bukti yang valid, sehingga mereka gagal dalam membuktikan. Hampir 30% mahasiswa tampak berhasil menyelesaikan pembuktian, tapi ternyata bukti tersebut tidak valid, salah satunya Putri. Putri memilih satu contoh spesifik untuk membuktikan suatu pernyataan implikasi yang general. Contoh yang dipilih Putri pun mengabaikan asumsi-asumsi yang diminta oleh soal. Selain itu, Putri tampak mencampuradukkan definisi dan teorema yang sekiranya terkait dengan soal. Oleh karena itu, pembelajaran Pengantar Analisis Riil hendaknya menekankan pemahaman definisi, teorema, lemma, maupun pernyataan matematika lainnya dengan lebih bermakna.

Abstract

To support students facing rapid technological development, teachers must provide real experience in the learning process. Linear programming materials that require visualization in their understanding can be taught by integrating GeoGebra software. This community service aims to strengthen teacher skills in using GeoGebra for linear programming learning media. Community service is carried out through training and mentoring with an active learning participant approach. The activities are carried out through three core stages: teacher training in mastering the GeoGebra interface, assistance in visualizing linear programming problems, and aid in solving linear programs. Although most of the participants stated that GeoGebra could help learn linear programming in the classroom, its implementation needs to consider various aspects, such as the preparation of learning tools and equipment, learning time, and student readiness.

Abstract

BMT Artha Mandiri is a cooperative that provides savings and loans services. In providing credit, BMT Artha Mandiri still uses the manual method, namely by looking at the ledger and history of each customer, to find out whether the applicant is worthy or not worthy of credit so that it is not effective and efficient. The purpose of this research is to make an application that can predict whether a prospective customer is eligible or not to be given credit. Predictions are made using the data mining classification method, namely the C4.5 algorithm based on the supporting data each customer has to classify which factors have the most influence on the level of credit payments in the cooperative. In a built application, the C4.5 algorithm produces a decision tree that is easy to interpret based on the existing variables. In the application, there are features that can be used to make decisions about customers who will apply for credit at the cooperative. The blackbox test results on the application show that the application has been able to run as expected, while the results of the algorithm test also show that the application has been able to implement the C4.5 algorithm correctly. In addition, the results of testing for accuracy show that the maximum average value of Accuracy is 79.19%.

Abstract

The objective of this study was to produce an educational game based on Van Hiele’s geometric thinking level called “MATHOLIC” on plane figures material in fourth-grade elementary school. This research was Research and Development (RD), which used the ADDIE model. The subjects of this study were fourth-grade students of Tlumpu Blitar State Elementary School. The data collection instruments were interview guidelines and questionnaires. The data was obtained in the form of qualitative data and quantitative data. The results of this study showed that: (1) the material experts gave the level validity of MATHOLIC 95,8%, while media experts gave the validity level of MATHOLIC 94,4%, and the classroom teacher gave the level validity of 98%, which meant that MATHOLIC was very valid; (2 )student responses in small group trials obtained a percentage of the practicality was 95% and in the field trial was 97,7% which meant that MATHOLIC was very practice; (3) the average score was 87,7 in the small group trial and 96,4 in the field trial which meant that the average was already above the Minimum Completeness Criteria score. MATHOLIC was declared valid and practical to be suitably used in learning mathematics. This study showed the validity and practicality of learning media in educational games that use van Hiele's theory. The findings of this study will be a solution for teachers who have difficulty teaching the material of plane figures  to make it more effective and easily understood.

Abstract

Previous studies have tried to improve students' independence in online mathematics learning. However, the Flipped Learning model integrated with GeoGebra is scarce as none of the existing syntaxes accommodate the model. As the existing syntax is based on three phases: pre-class activity, in-class activity, and post-class activity. This research aims to develop GeoGebra-based Flipped Learning syntax to increase students' independence in learning mathematics. The main difference between the existing syntax and the developed one is the integration of GeoGebra in the pre-class activity. The integration is based on previous studies showing that using GeoGebra can improve student’s learning achievements. It research employed the Design-Based Research (DBR) model involving 125 second-year undergraduate students of a private university in Indonesia. The syntax results were obtained from the study, indicating an increase in the average value of student independence in learning mathematics based on learning independence, confidence, level of discipline, sense of responsibility, level of initiative, and self-control. This developed syntax is expected to help teachers streamline online mathematics learning.

Abstract

This research investigates the mathematical concepts embedded within Batik Truntum motifs, including geometry, analysis, arithmetic, and algebra. Employing a qualitative methodology with an ethnographic approach, the study addresses four critical questions: "Where should I begin the search?", "How do I locate the concepts?", "How do I identify significant findings?", and "How do I comprehend these findings?". Through addressing these questions, the researcher successfully analyzed the mathematical concepts inherent in Batik Truntum. Of the four primary mathematical concepts, only geometry was substantiated by experts, encompassing sub-concepts such as geometric transformations, line relationships, and planar geometry. Specifically, transformation geometry includes translation and reflection, while the study of line relationships involves line alignment, and planar geometry covers the topic of circles. This research aims to ensure that the millennial generation remains connected to batik as a vital part of Indonesia's cultural heritage, preventing cultural erosion amidst technological advancements through the intricate and exploratory study of mathematics.
