Abstract

The rapid advancement of digital technology requires mathematics teachers to have strong pedagogical competence in designing and managing learning materials effectively. However, many teachers still face challenges in preparing comprehensive learning documents, such as Annual Programs (Prota), Semester Programs (Promes), teaching modules integrated with student worksheets (LKPD), assessment instruments, reflections, document covers, and class administration records. This study aimed to develop and assess the validity of SIPENA (Sistem Perangkat Pembelajaran/Learning Administration System), an AI-integrated web-based application that automatically generates complete learning documents for mathematics teachers. The development followed the 4D model (Define, Design, Develop, and Disseminate), limited to the first three stages. Expert validation was conducted by a media expert and a content expert using Likert-scale instruments. The results showed a media validity 86.36% and content validity of 96.84%, both were categorized as Very Valid. Usability was awarded the highest score by media experts (96.00%), while content experts confirmed that their product matched Merdeka Curriculum perfectly (100.00%). This study finally provides a valuable contribution to the field of AI-based educational technology in mathematics education context in Indonesia by showing that SIPENA can serve as both a valid and feasible platform to use for supporting mathematics teachers pedagogical competences in the digital era. This study was intentionally limited to evaluating the validity aspect of SIPENA development, while its effectiveness and effect size will be explored in a subsequent publication.

Abstract

This study aims to analyze the problem-solving and critical thinking abilities of prospective mathematics teachers in solving Higher Order Thinking Skills (HOTS) problems on lines and angles through error analysis. The study employed a qualitative descriptive approach. The research subjects consisted of 20 fourth-semester students of the Mathematics Education Study Program at Institut Pendidikan Tapanuli Selatan (IPTS). Data were collected through HOTS geometry tests, task-based interviews, and documentation of students’ written work. Error analysis was conducted using Newman’s Error Analysis (NEA), while critical thinking and problem-solving abilities were analyzed using the FRISCO and Krulik-Rudnick frameworks. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña, which includes data reduction, data display, and conclusion drawing. The results showed that students’ abilities were still in the moderate to low category. The dominant errors occurred at the transformation and process skills stages, indicating difficulties in converting visual representations into mathematical models and selecting appropriate solution strategies. In addition, students demonstrated weaknesses in critical thinking, particularly in reasoning, inference, and overview indicators. These errors were influenced by epistemological and ontogenic obstacles related to weak spatial ability and conceptual understanding of geometry. Therefore, HOTS-based learning emphasizing visualization, critical thinking, and systematic problem-solving is needed to improve prospective teachers’ mathematical abilities.

Abstract

Manajemen waktu merupakan keterampilan fundamental yang perlu diterapkan dalam pendidikan formal jenjang SMP. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman dan kesadaran siswa SMP tentang pentingnya manajemen waktu dalam kegiatan belajar, serta membekali siswa dengan keterampilan praktis dalam menyusun jadwal belajar yang efektif dan efisien. Mitra kegiatan pengabdian ini adalah siswa SMPN 1 Rajapolah. Metode yang digunakan adalah pendidikan masyarakat melalui pendekatan penyuluhan langsung yang bersifat interaktif, mencakup penyampaian konsep dasar manajemen waktu, dampak buruk pengelolaan waktu yang tidak efektif, strategi penyusunan jadwal belajar, serta tips menghindari prokrastinasi, yang diakhiri dengan pemberian angket sebagai instrumen evaluasi. Hasil evaluasi menunjukkan rata-rata tingkat pemahaman dan sikap siswa mencapai 89% dengan kategori Sangat Baik, mencakup aspek pentingnya manajemen waktu (90%), cara manajemen waktu yang efektif (89%), dan perencanaan membuat jadwal prioritas (88%). Temuan ini bermakna bahwa metode penyuluhan tatap muka yang interaktif terbukti efektif membangun kesadaran siswa terhadap pengelolaan waktu belajar yang terstruktur dan terencana.

Abstract

This study integrates Linear Programming (LP) and Geographic Information System (GIS) to optimize land and water resource utilization in Indonesian rural areas. The proposed multi-period LP model aims to maximize farmers' net profit under land, water, and labor constraints, where decision variables represent the land area (in tumbak) allocated to each crop per period. Conducted in three agricultural villages of Garut Regency with 60 farmer respondents selected through stratified sampling, the model was solved using Excel Solver and spatially visualized through GIS. Results show an optimal cultivated area of 453.202 tumbak, utilizing 16,412.49 m³ of water and 5,319.098 man-days of labor, producing Rp 2,078,047,500 in gross revenue and Rp 26,493,556 in net profit. Land-use efficiency improved by 64.8% from baseline conditions, with land as the main binding constraint. The model offers a practical decision-support tool for policymakers to plan crop rotation, irrigation scheduling, and sustainable land-use strategies.

Abstract

Kemampuan penalaran matematis, analisis, penilaian, dan refleksi diri merupakan komponen penting dalam pendidikan matematika karena memungkinkan mahasiswa untuk mengembangkan kemampuan berpikir matematis mereka. Namun, menurut sejumlah penelitian, kemampuan penalaran matematis mahasiswa masih belum memadai. Kapasitas untuk mengatur diri sendiri dan mengelola proses belajar sendiri dikenal sebagai self-regulated learning (SRL). Studi ini bertujuan untuk memberikan uraian rinci tentang kemampuan penalaran matematis mahasiswa dan tingkat self-regulated learning, serta untuk meneliti korelasi antara keduanya, mengukur kekuatannya, dan mengukur sejauh mana self-regulated learning mahasiswa berkontribusi pada kemampuan penalaran matematis mereka. Metode kuantitatif berdasarkan jenis penelitian korelasional digunakan dalam penelitian ini. Dalam penelitian ini, 22 mahasiswa yang terdaftar dalam program studi pendidikan matematika semester enam dipilih menggunakan metode purposive sampling. Tes kemampuan penalaran matematis dan kuesioner self-regulated learning digunakan dalam penelitian ini. Data dianalisis menggunakan berbagai ukuran seperti statistik deskriptif, uji normalitas dan linearitas, korelasi pearson product moment, dan koefisien determinasi. Penelitian menemukan bahwa kemampuan penalaran matematika mahasiswa cukup tinggi (rata-rata 81,18) dan tingkat self-regulated learning mereka cukup tinggi (rata-rata 91,27). Dengan tingkat signifikansi 0,001 dan koefisien korelasi 0,716, temuan uji korelasi menunjukkan hubungan positif dan signifikan secara statistik antara kemampuan penalaran matematis dan self-regulated learning. Dengan hasil ini, dapat dikatakan bahwa korelasi antara kedua variabel tersebut cukup kuat. Koefisien determinasi juga mengungkapkan bahwa kapasitas mahasiswa untuk self-regulated learning menyumbang 51,2% dari keseluruhan kemampuan mereka dalam penalaran matematis. Oleh karena itu, kapasitas berpikir matematika mahasiswa dapat ditingkatkan melalui penggunaan strategi pembelajaran mandiri.

Abstract

Geometry learning at the Junior High School (SMP) level frequently faces challenges due to the abstract nature of the objects, which impacts students' low spatial literacy. This issue is exacerbated by the dominance of conventional teaching methods that lack interactive digital media. This community service activity aims to enhance students' spatial literacy at SMP IT Qoshrul Muhajirin through learning assistance using ethnomathematics-based digibooks. The method employed consists of four stages: Planning, Acting, Observing, and Reflecting. Data were collected through observation, student response questionnaires, as well as pre-test and post-test instruments. The results indicate a significant improvement in students' spatial literacy by 22.70%, with the average score increasing from 43% in the initial stage to 65.70% following the assistance. Furthermore, 91.3% of students provided positive responses regarding the ease of use of the media, and 90.4% felt more motivated in learning. It can be concluded that the use of ethnomathematics-based digibooks is effective as an innovative learning solution capable of integrating digital technology with local cultural values to optimize students' spatial abilities.
