Abstract. Ethnomatematics is the mathematics that is applied by a group of culture unconsciously. The study is conducted at Kalibaru Banyuwangi. The aim of the study is to to describe ethnomatematics and to make a pack of test questions concerning to ethnomatematics on kitchen equipment craftsmen. The type of this research is qualitative with the ethnographic approach and two subject research. Calculating activity appears when determining the length and width of a body with a certain size, determining the height of the filter location, determining the size of the length for the base and lid, making the net cover, determining the volume of parts, determining wages, and making certain diameters. Measuring activity arises when measuring the location of the filter's height, measuring the length and width of the casing, measuring the length of the radius of the base and lid, and measuring the length of the wire. Designing activity arises when the craftsman makes a ruler, makes a filter hole, makes the nets close, and emerge mathematical concept about two-dimentional figure and three-dimentional figure. Making student teaching materials in the form of a package of test questions with the topic of ethnomatematics on craftsmen in the making of dandang with material to construct curved side spaces. Keywords: ethnomatematics. kitchen utensils, student teaching materials

Abstract

This study aims to describe the ability of spatial geometry of class XI MIPA 1 SMA Negeri 2 Jember in terms of David Keirsey's personality type. Spatial ability in this study is the ability to understand the world of space based on elements of spatial abilities which include: spatial perception, mental rotation, and spatial visualization. This type of research is a descriptive study with a qualitative approach. The data collection method in this research is questionnaire, spatial test, and interview. Then, based on the results of the test and interview analysis, it was found that the Guardian students could fulfill all spatial indicators. Artisan students in imagining and rotating spaces can think quickly and answer questions correctly, compared to guardian and idealistic students. Idealistic students in the ability to see the surface of the unit cubic structure more than the point of view (from the front, right side, and top) cannot describe it precisely. Meanwhile, rational students on the mental rotation element for the first indicator are still unable to rotate a spatial shape and can imagine the rotation or rotation of a spatial shape accurately.

Abstract

Educational digitalization is characterized by technology-assisted media, leading to improved students’ digital literacy. One of these media is the electronic worksheet for students. An initial observation revealed that learning activities at Public Islamic Senior High School (MAN) in Bondowoso still operationalized conventional books as the sole media. This study aimed to develop electronic worksheets for students using valid, effective, and practical Geogebra-assisted live worksheets, guided by the 4-D model designed by Thiagarajan. This model consisted of four stages, i.e., define, design, develop, and disseminate. Data were collected through observation, tests, and questionnaires. Test questions were used to determine the level of effectiveness, and questionnaires were used for validity and practicality tests. The results revealed very high validity. The effectiveness analysis exhibited an N-Gain percentage of 76%, signifying a satisfactory effectiveness rate. The practicality analysis marked 86.20%, which is classified into a good category. The analysis results corroborated that electronic worksheets for students have proven valid, effective, and practical, demonstrating the potential to improve students' digital literacy.

Abstract

ecanduan media sosial adalah salah satu kasus yang dapat dianalisis menggunakan matematika. Kasus ini dapat dikemas menjadi model matematika. Model matematika yang digunakan pada penelitian ini adalah SEARQ. Metode runge-kutta orde 15 adalah metode numerik yang digunakan untuk menyelesaikan kasus kecanduan media sosial pada penelitian ini. Penelitian ini menganalisa konvergensi, efektivitas, dan efisiensi metode runge-kutta orde 15 serta melakukan simulasi numerik untuk melihat perilaku penyebaran kasus kecanduan media sosial. Data yang digunakan dalam penelitian ini diperoleh dari hasil kuesioner dan metode dokumentasi. Hasil dari penelitian ini mendapatkan dua formula metode runge-kutta orde 15 yang dinamakan RK15X dan RK15Y. Hasil analisa kasus kecanduan media sosial secara numerik menunjukkan bahwa kasus kecanduan media sosial ini bersifat endemik. Kecanduan media sosial dapat menjadi kasus yang merebak dan menetap dari waktu ke waktu.
