Abstract

This community service program aims to develop instructional teaching aids through multidisciplinary collaboration between lecturers and students from various study programs at the Islamic National University of Indonesia (UNIKI). The activity was carried out at SDN 8 Juli, an elementary school in a rural area of Bireuen Regency, Aceh, which faces limitations in concrete learning media. The approach used was the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), which allows for a systematic and participatory development process. Based on the needs analysis, it was found that students had difficulty understanding abstract concepts in science and English subjects. To address this challenge, the team designed several innovative teaching aids, such as an erupting volcano model, a diorama of the rain process, bilingual science vocabulary cards, and thematic student worksheets (LKS). These media were then implemented in thematic learning in grades III and V. The results of the implementation showed improvements in conceptual understanding, learning interest, and student participation. Teachers also expressed enthusiasm and willingness to use the media independently in the future. Evaluation was conducted through classroom observation and teacher reflection, indicating that the developed media were appropriate for the needs and easy to apply. This activity demonstrates that cross-disciplinary collaboration can produce effective and sustainable learning media. This model is worthy of replication in other elementary schools, particularly those in resource-limited areas.

Abstract

Analisa data uji hidup adalah salah satu analisa statistik yang membahas tentang daya tahan hidup suatu bahan atau individu pada keadaan operasional tertentu. Ada beberapa distribusi yang terdapat dalam analisa data uji hidup. Diantaranya adalah distribusi Pareto dan distribusi Normal. Dalam penelitian ini gabungan dari distribusi Pareto dan distribusi Normal akan menghasilkan distribusi Mixture Pareto-Normal (MPN). Peluang sukses pada distribusi Pareto dan peluang gagal pada distribusi Normal dimana fungsi distribusi MPN akan bernilai nol, positif atau negatif dengan parameter-parameter peluang sukses dan peluang gagal yang berbeda. Untuk mengestimasi parameter dari distribusi MPN menggunakan metode Maximum Likelihood Estimate (MLE) dengan Algoritma EM (Ekspektasi Maksimasi) dan menentukan fungsi Reliabilitasnya. Estimator parameter yang masih implisit dapat diselesaikan dengan metode Newton-Raphson didasarkan pada pemakaian turunan (yaitu kemiringan), taksirannya menggunakan deret Taylor. Prosedur E menentukan fkp (fungsi kepadatan peluang) distribusi MPN, melog-kan, menentukan ekspektasi bersyarat dan mensubstitusikan distribusi Normal dan distribusi Pareto pada persamaan fkp distribusi MPN yang sudah dilog-kan. Prosedur M mendapatkan estimator dari parameter-parameter distribusi MPN yang sudah didifferensialkan yaitu diperoleh hasil yang eksplisit. Sedangkan estimator diperoleh masih dalam bentuk fungsi implisit (masih mengandung parameter itu sendiri pada distribusi Pareto). Penentuan fungsi Reliabilitas dari distribusi MPN dengan mensubstitusikan distribusi MPN dengan peluang sukses yang bernilai positif pada fungsi Reliabilitas Mixture karena peluang sukses yang bernilai positif akan dapat menentukan fungsi Reliabilitas dari distribusi MPN. Sehingga daya tahan hidup dengan menggunakan distribusi MPN dapat dilakukan.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play an important role in economic development but often face limitations in digital literacy, English language proficiency, and basic business management, which reduce their competitiveness in the digital era. This community service program aimed to optimize digital media as an integrated platform to strengthen practical English skills and business management competencies among MSME actors. The program employed a participatory and practice-oriented approach consisting of training, hands-on practice, and continuous mentoring. Training activities focused on functional English for business communication, digital media utilization for marketing, and basic management practices such as branding and simple bookkeeping. The results indicate improvements in participants’ ability to use English for product promotion, increased use of digital media for marketing activities, and greater awareness of structured business management. Participants also showed higher engagement and confidence in applying digital tools to their daily business operations. These findings suggest that integrated digital media–based capacity building is effective in supporting MSME empowerment and sustainable economic development.

Abstract

This study examines the role of computational thinking (CT) ability as a foundational skill for solving contextual mathematical problems among informatics students. Contextual mathematical problems require students to translate real-world situations into mathematical representations, apply appropriate strategies, and interpret solutions meaningfully. Such processes align closely with core components of computational thinking, including decomposition, pattern recognition, abstraction, and algorithmic thinking. This study employed a quantitative correlational design involving undergraduate informatics students. Data were collected using a computational thinking test and a contextual mathematical problem-solving assessment. Statistical analysis was conducted using correlation and regression techniques to determine the contribution of CT ability to students’ problem-solving performance. The findings indicate that computational thinking ability has a significant and positive effect on students’ ability to solve contextual mathematical problems. These results suggest that strengthening computational thinking skills is essential for enhancing mathematical problem-solving competence, particularly in informatics education. The study provides empirical support for integrating computational thinking explicitly into mathematics-related courses for informatics students.
