Abstract

The problem of misconceptions about flat building in geometry, especially quadrilateral, has been very frequently reviewed by practitioners and educational researchers. However, this remains an inherent problem to date and results in confusion of the basic concept of quadrilaterals. Therefore in this study a geometry-themed learning media was created, especially quadrilateral in the form of geometric t-shirt design to make it easier for students to understand the definitions and differences between the quadrilateral itself. Based on the results of the study, it was found that geometric T-shirt learning media was declared valid with a score above 3 or in the good category. Whereas for the fulfillment of practical criteria, a value of 3.5 is obtained, which means that the shirt of geometry does not require revision and is practical. The value of effectiveness is effective, where the results obtained that the geometry shirt provides learning outcomes that have a significant effect on the achievement of the defined KKM and the achievement of a positive response of 97.12% by students. So that the geometry T-shirt learning media is declared valid, practical and effective in accordance with the criteria for developing instructional media.

Abstract

Mathematics is one of the important subjects in realizing the goals of education in Indonesia. However, in reality there are many students who have different problem solving abilities between one and the other and many students make mistakes when solving problems. The mistakes that are often carried out by students can also be influenced by differences in learning styles possessed. Therefore this article aims to describe differences in errors made by reflective-impulsive students in solving mathematical problems. This research is a qualitative descriptive that involving 2 research subjects with each subject having a different learning style. This research was conducted in class VII Pakusari Jember 1 Junior High School in the academic year of 2018/2019. The results of data analysis showed that differences in mistakes made by junior high school students with reflective-impulsive learning styles in solving mathematical problems were located at the stage of determining mathematical models and at the stage of completing mathematical models that had been made with the percentage of impulsive learning styles when compared to a subject that is reflective learning style.

Abstract

Let G be a connected and simple graph with vertex set V(G) and edge set E(G). For a graph G, we define k-labeling such that the edges of G are labeled with integers {1,2,3,....,k_e} and the vertices of G are labeled with even integers {0,2,4,....,2k_v}, where k=max{k_e, 2k_v}. If there is a different weight for all edges, then the labeling is called edge irregular reflexive k-labeling. The weight of edge xy, notated by wt(xy) is defined as a sum of label of x, label of xy, and label of y. The minimum k for which G has an edge irregular reflexive k-labeling is defined as reflexive edge strength of G, symbolized by res(G). In this research, we determined the reflexive edge strength of several Cartesian graphs, namely P_5xP_n, S_4xP_n, C_5xC_n, and F_3xP_n. Keywords: Edge irregular reflexive k-labeling, reflexive edge strength, Cartesian graph.

Abstract

Tahun 2022 luas hutan Indonesia sebesar 125,76 hektar atau 62,97% dari luas daratan Indonesia. Hutan memegang peranan penting bagi kahidupan manusia, salah satunya adalah hutan sebagai sumber air. Kebakaran hutan menjadi ancaman yang serius bagi keberlangsungan hutan di Inodonesia. Kebakaran hutan di Indonesia terjadi hampir setiap tahun dengan luas hutan yang terbakar setiap tahunnya berfluktuatif. Kebakaran hutan disebabkan akibat aktivitas manusia dalam pembukaan lahan, musim kemarau, atau faktor lainnya. Hutan yang rusak dapat berdampak kepada banyak hal, salah satunya yakni kodisi sumber air atau kondisi aliran sungai yang dapat ikut menurun secara kualitas atau kuantitasnya. Salah satu mitigasi bencana yang dapat dilakukan dalam fenomena kebakaran hutan adalah dengan melakukan analisis data dalam memodelkan prediksi luas kebakaran hutan di Indonesia. Metode prediksi yang dapat digunakan adalah analisis runtun waktu model ARIMA dan analisis regresi linier. Setelah dilakukan analisis data diperoleh kesimpulan (1) Model ARIMA (3,2,0) dan model regresi linier sederhana dengan variabel independen status el-nino, layak digunakan untuk memodelkan prediksi luas kebakaran hutan di Indonesia. (2) Variabel independen status elnino berpengaruh terhadap luas kebakaran hutan di Indonesia, dengan nilai korelasi ( R ) sebesar 0.462. (3) Tahun 2025 prediksi luas kebakaran hutan Indonesia untuk model ARIMA(3,2,0) adalah sebesar 0.457 juta hektar. (5) Untuk model regresi linier sederhana jika tahun 2025 terjadi el nino, luas kebakaran hutan Indonesia diprediksi sebesar 1.09 juta hektar. (6) Untuk model regresi linier sederhana jika tahun 2025 tidak terjadi el nino, luas kebakaran hutan Indonesia diprediksi sebesar 0.45 juta hektar.

Abstract

This community service activity aims to increase awareness of Occupational Health and Safety (OHS) among rubber cord workers who process motorcycle tire waste in Sukorejo Village, Bangsalsari Subdistrict, Jember Regency. This home-based industry poses high occupational risks, such as exposure to tire dust, fine particles, hazardous chemicals, and the potential for injuries from sharp tools. Low understanding and use of Personal Protective Equipment (PPE) exacerbate the risks of respiratory issues, skin irritation, and cuts. The method used was an interactive 3-hour session, including lectures, participatory discussions, and demonstrations on proper PPE usage. Evaluation results showed a significant increase in workers' knowledge about specific workplace risks and the importance of PPE. Additionally, the workers demonstrated strong motivation to adopt safer, healthier, and more productive work practices on an ongoing basis. The impact of this activity is expected to reduce workplace accidents and work-related illnesses while enhancing productivity in the rubber rope processing home industry. Future recommendations include regular mentoring and the provision of affordable PPE to ensure the sustainability of OSH practices in the field.
