Abstract

This study was motivated by students’ low mathematical problem-solving skills, the lack of innovative learning models, and the limited use of technology in learning media. The purpose of this research is to determine the effect of a problem-based learning model assisted by digital student worksheets on students’ mathematical problem-solving skills. This quasi-experimental research involved all eighth-grade students at one of the junior high schools in mataram city. The sample consisted of class VIII A as the experimental class, which received PBL with digital worksheets, and class VIII B as the control class, which received PBL with printed worksheets. Data were collected using a mathematical problem-solving test and analyzed using a t-test and effect size. The results showed that the use of digital worksheets had a significant effect on students’ mathematical problem-solving skills. The average score of the experimental class increased from 47.75 (pretest) to 70.12 (posttest), while the control class increased from 49.46 to 62.05. The t-test showed that   at a 0.05 significance level. The effect size was 0.71, categorized as large, indicating that the applied model and media were effective. This study shows that digital worksheets in problem-based learning can enhance students’ problem-solving skills.

Abstract

Penelitian ini bertujuan untuk merancang dan membangun sebuah alat etching PCB otomatis berbasis mikrokontroler Arduino, yang berfungsi untuk mempercepat dan menyederhanakan proses pembuatan papan sirkuit cetak secara presisi. Alat ini dilengkapi dengan Motor DC sebagai penggerak utama, yang kecepatannya diatur melalui sinyal PWM untuk memastikan pergerakan wadah berisi cairan ferric chloride berlangsung merata. Sistem juga dilengkapi dengan sensor load cell yang berfungsi untuk membaca berat ferric chloride, sehingga ketika berat tercapai, pompa akan secara otomatis mengalirkan air ke dalam wadah etching sesuai takaran. Pengguna cukup mengatur parameter di awal dan memantau proses dari jarak aman tanpa perlu kontak langsung dengan bahan kimia. Pengujian alat menunjukkan bahwa motor dapat bergerak stabil dengan variasi kecepatan yang sesuai, serta sistem load cell dan pompa bekerja secara otomatis saat berat ferric chloride mencapai nilai yang ditentukan. Alat ini berhasil menyederhanakan proses pencelupan PCB ke dalam cairan etching dengan hasil yang lebih konsisten dan aman, serta mengurangi paparan langsung terhadap bahan kimia berbahaya. Sistem bekerja secara efektif dan efisien untuk keperluan pembuatan PCB skala kecil maupun eksperimen laboratorium.

Abstract

Keberhasilan seorang siswa sangat bergantung pada kesiapan guru dalam merancang suatu desain pembelajaran. Ketersediaan media pembelajaran dapat memudahkan guru dalam menyampaikan materi pembelajaran dengan baik sehingga tujuan pembelajaran dapat tercapai. Berdasarkan observasi di lapangan, lebih tepatnya di SMPN 22 Mataram menunjukan bahwa belum tersedianya media pembelajaran interaktif yang dikembangkan. Sumber belajar yang biasanya digunakan adalah lembar kerja siswa (LKS) yang masih belum menggabungkan konsep matematika dengan kehidupan sehari-hari. Dengan demikian. Tujuan penelitian ini adalah menghasilkan media pembelajaran interaktif berbasis matematika realistik yang valid dan praktis. Jenis penelitian yang digunakan adalah penelitian pengembangan (research & development) dengan model pengembangan 4D dengan tahapan pendefinisian (define), Perancangan (design), pengembangan (development), dan penyebaran (dissemination). Akan tetapi, pada tahap penyebaran (dissemination) tidak dilaksanakan karena keterbatasan waktu. Instrumen yang digunakan pada penelitian ini adalah lembar observasi dan angket kepraktisan. Teknik analisis data yang digunakan bersifat kuantitatif, yaitu analisis berdasarkan data yang diperoleh. Teknik analisis data terdiri dari tiga alur kegiatan: reduksi data, penyajian data, penarik kesimpulan. Hasil penelitian ini menghasilkan produk media pembelajaran interaktif berbasis matematika realistik yang termasuk dalam kategori sangat valid dengan skor 0.86 dan termasuk dalam kategori sangat praktis dengan skor 98%. Setelah menggunakan media dalam proses pembelajaran dapat disimpulkan bahwa media pembelajaran interaktif berbasis matematika realistik dinyatakan sangat valid dan sangat praktis. Media pembelajaran interaktif ini diharapkan menjadi salah satu alternatif alat bantu guru dalam pembelajaran sehingga siswa dapat membangun pemahaman siswa dalam memahami konsep matematika realistik.

Abstract

This research was conducted to determine the effect of cooperative learning model type think talk write (TTW) on mathematical communication skills in students of SMPN 13 Mataram class VIII on statistics material. Quantitative approach with quasi experimental method was used in this research. The population in this study was all VIII grade students of SMPN 13 Mataram consisting of five classes, with a sample consisting of two classes, namely class VIII E as an experimental class using the cooperative learning model of think talk write (TTW) type and class VIII A as a control class using direct learning model. Data collection techniques used observation sheets, documentation, and tests. The results of data analysis showed that there was an average difference between the experimental and control classes. The t-test results obtained a t-count value of 2,939, and the t-table value obtained a value of 1,669, indicating that the t-count value was greater than the t-table. Thus, the Think Talk Write (TTW) cooperative learning model has a positive effect on students' mathematical communication skills. This research suggests the application of TTW model as an effective learning strategy to improve students' mathematical communication skills at junior high school level

Abstract

This study aims to describe the ability to solve mathematical problems on two-variable linear equation system material based on the locus of control in grade VIII students. This study used qualitative methods to obtain a sample of 72 students using purposive sampling. Data collection techniques use locus of control questionnaire instruments and problem-solving ability test questions. The results of this study showed that students with a strong external locus of control were only able to reach a step of understanding the problem. Meanwhile, students with a balanced internal and external locus of control can reach two steps namely, understanding the problems and devising a strategy. This happens because, students with a strong external locus of control, as well as students with a balanced internal and external locus of control, are less trying and less active in seeking information related to the problems at hand, and are easily influenced by others. Meanwhile, students with a strong internal locus of control can reach three steps namely, understanding the problems, devising a strategy, and carrying out the strategy. This happens because students have a strong internal locus of control easily satisfied with the results they get with the effort they make.
