Abstract

This study aims to implement an Augmented Reality-based Student Worksheet (LKPD) on the topic of three-dimensional shapes with flat surfaces to optimize the mathematical conceptual understanding of junior high school students in Pinangsori. The study uses the Plomp development model, which consists of five phases: initial investigation, design, realization, testing-evaluation-revision, and implementation. The instrument used is a test sheet measuring students' mathematical conceptual understanding. The research subjects consist of 29 students. Effectiveness is determined based on students' test scores. The analysis results show that the Augmented Reality-based LKPD (BASTAR) for the topic of three-dimensional shapes with flat surfaces has an effectiveness of 96%>85% of students achieving mastery with effective criteria. The conclusion of the study is that the implementation of the Augmented Reality-based LKPD (BASTAR) is considered effective for teaching three-dimensional shapes with flat surfaces to junior high school students.

Abstract

The research conducted aims to determine the effectiveness of educational game-based mathematics learning media snakes and ladders to improve mathematical problem-solving skills of class X-2 students of SMA Negeri 1 Angkola Barat. The research method used in this study is using classical completeness. The subjects in this study came from 3 validators, as well as class X-2 students. The data collection technique used was using a questionnaire validation question and test for effectiveness testing. The results of the test question instrument validation analysis obtained a total percentage of achievement of 90% with the category "Very Valid". The results of the effectiveness data analysis obtained an overall average value of 75.45 with the category "Complete" and a percentage of completeness of 64.70% with the category "Effective". Based on the results obtained, it can be concluded that the resulting learning media is valid, practical, and effective.

Abstract

Students pay less attention to the teacher during the learning process because students find it difficult to understand the learning material, especially in mathematics. The purpose of this study was to determine the effectiveness of the contextual learning model on students' mathematical problem-solving abilities on the material of two-variable linear equation systems in Class X of SMK Negeri 1 Angkola Timur. The type of research used by the researcher is quantitative research. In this study, the researcher used the True-Experienced Design design with the One Group Pretest and Posttest Design type. The population was all students of Class X at SMK Negeri 1 Angkola Timur consisting of 6 classes totaling 92 students. Based on the data analysis, the researcher drew conclusions based on the results of data collection, there was an effectiveness of the contextual learning model on the material of two-variable linear equation systems on students' mathematical problem-solving abilities. This is evidenced by the results of the paired sample test that has been conducted in the experimental class. It can be concluded that H0 in the experimental class is rejected and Ha is accepted because the sig value (2-tailed) in the experimental class is 0.00 less than 0.05. Furthermore, based on inferential statistics using the pair sample t-test, (SPSS version 27), the results show a significance value of less than 0.05 (0.000 < 0.05). This means that the constructivism learning model is effectively used for the mathematical problem solving abilities of class X students of SMK Negeri 1 Angkola Timur.

Abstract

Penelitian ini bertujuan untuk menganalisis kesulitan membaca (reading difficulties) pada siswa kelas III di SDN 200208 Padangsidimpuan. Penelitian ini menggunakan pendekatan kualitatif dengan desain deskriptif untuk menggambarkan secara mendalam fenomena kesulitan membaca yang dialami siswa. Penelitian dilaksanakan pada tanggal 9 Februari hingga 16 Maret 2026. Subjek penelitian ditentukan menggunakan teknik purposive sampling dengan kriteria siswa yang mengalami kesulitan membaca. Pengumpulan data dilakukan melalui observasi, wawancara, tes membaca, dan dokumentasi. Analisis data menggunakan model interaktif yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan, serta diuji keabsahannya melalui triangulasi sumber dan teknik. Hasil penelitian menunjukkan bahwa siswa mengalami berbagai bentuk kesulitan membaca, yaitu kesulitan mengenali huruf, menggabungkan suku kata, membaca secara lancar, kesalahan dalam membaca kata, serta rendahnya pemahaman terhadap isi bacaan. Faktor penyebab kesulitan membaca meliputi faktor internal seperti rendahnya minat dan motivasi membaca, serta faktor eksternal seperti kurangnya dukungan keluarga dan penggunaan metode pembelajaran yang kurang variatif. Penelitian ini menegaskan bahwa kesulitan membaca merupakan permasalahan kompleks yang memerlukan penanganan secara komprehensif melalui strategi pembelajaran yang tepat dan dukungan lingkungan yang memadai.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan pemahaman siswa tentang pentingnya Tiga Dosa Besar Dunia Pendidikan merujuk pada perundungan (bullying), kekerasan seksual, dan intoleransi. Ketiga hal tersebut dianggap sebagai perbuatan tercela yang dapat merusak ekosistem pendidikan, merugikan peserta didik, dan menghambat tercapainya tujuan pendidikan yang berkarakter dan beradab. Penguatan Karakter Siswa adalah proses pembinaan nilai, sikap, dan perilaku positif pada peserta didik agar memiliki integritas, tanggung jawab, serta rasa hormat terhadap diri sendiri dan orang lain. Lingkungan Sekolah Humanis dan Bermartabat bermakna suatu kondisi sekolah yang menjunjung tinggi nilai kemanusiaan, menghargai keberagaman, menolak kekerasan, serta menumbuhkan budaya saling menghormati, sehingga sekolah menjadi tempat yang aman, nyaman, dan layak untuk belajar.
