Abstract

This article aims to present the formulation of the hadith authenticity method formulated by Jonathan A. C. Brown in his theory named the Three-Tiered Method. This investigation is carried out through three steps; First, demands for a source of hadith, second, evaluates the reliability of that source, third, seeks corroboration for the hadith. Brown also argues that the third step is considered pivotal in hadith criticism. The more sources of the report, the more credible the report is. In the theory of historical evaluation of western scholar, such belief is called the criterion of multiple attestation. Briefly, quantity changes lead to quality changes. Therefore, the author's reflection on the issue relating to the hadith about the suggestion to wear a white dress (which has been criticise using this theory) proves this hadith to be authentic. Abstrak: Artikel ini bertujuan untuk mempresentasikan formulasi metode autentisitas hadis yang dirumuskan oleh Jonathan A. C. Brown melalui teorinya Three Tiered Method. Investigasi hadis diaplikasikan dalam tiga langkah. Pertama, tuntutan adanya sumber hadis. Kedua, mengevaluasi keterpercayaan sumber hadis. Ketiga, mencari penguat sebuah hadis. Brown berpendapat bahwa langkah ketiga dianggap cukup krusial dalam kritik hadis. Semakin banyak sumber laporan maka akan muncul kepercayaan yang tinggi terhadap laporan tersebut. Dalam evaluasi historis versi Sarjana Barat, hal ini disebut kriteria pengesahan berganda (the criterion of multiple attestation). Pendek kata, kuantitas akan berubah menuju kualitas. Refleksi penulis dalam kasus hadis tentang anjuran berpakaian putih menggunakan teori tersebut membuktikan bahwa hadis ini otentik

Abstract

MSMEs in Nagari Tanjung Bonai Aur, Sijunjung Regency, possess high-potential local flagship products, including eucalyptus oil, kalamai, and kembang loyang cakes. However, limited digital literacy and insufficient utilization of e-commerce platforms constrain their market expansion. This community service program aimed to enhance MSME digital capacity through e-commerce training and continuous assistance using a Participatory Action Research (PAR) approach, structured into a two-day intensive workshop and two months of post-training mentoring. Program evaluation employed a mixed-methods approach, combining qualitative action research with quantitative pretest-posttest measurements across 25 participating MSMEs. The findings demonstrated a statistically significant improvement in participants' digital literacy score from  to  ( , Paired Sample t-test). All 25 MSMEs successfully established and independently managed online storefronts on Tokopedia and Shopee, achieving an initial 45 verified online transactions during the mentoring period. The PAR approach proved highly effective in fostering community engagement, digital store management skills, and self-reliance among rural MSMEs. This intervention model provides an adaptable framework for digital transformation in similar rural contexts, provided local product characteristics and digital readiness are adequately addressed.

Abstract

This study was motivated by the suboptimal dribbling ability of students participating in the basketball extracurricular program at SMAN 8 Padang, which was assumed to be related to agility and hand-eye coordination. This study aimed to determine the relationship between agility and hand-eye coordination with dribbling ability, both partially and simultaneously. The study employed a quantitative approach with a correlational design. The population and sample consisted of 12 male students selected using total sampling. Data were collected through agility, hand-eye coordination, and dribbling ability tests. Data were analyzed using Product Moment correlation and multiple correlation. The results showed a significant relationship between agility and dribbling ability, with a correlation coefficient of 0.620 and a contribution of 38.44%. There was also a significant relationship between hand-eye coordination and dribbling ability, with a correlation coefficient of 0.600 and a contribution of 36.00%. Simultaneously, both variables showed a significant relationship, with a correlation coefficient of 0.660 and a contribution of 43.60%. Thus, agility and hand-eye coordination are significantly related to students' dribbling ability.

Abstract

Conventional Digital Audio Workstation (DAW) learning is currently constrained by high hardware specifications, software licensing costs, and limited opportunities for students to engage in independent practice outside computer laboratory sessions. This study aims to analyze the implementation of the Soundtrap platform as a cloud-based learning medium and to examine students' experiences and responses during its use in the Basic Digital Audio Workstation course within the Music Education Study Program, Faculty of Languages and Arts, Universitas Negeri Padang. This study employed a descriptive qualitative approach. The participants were one course lecturer and 37 students from three classes selected through purposive sampling. Data were collected through classroom observations, analysis of students' digital music projects and course documents, a student survey, and semi-structured interviews with the lecturer and seven students, and were analyzed using the interactive model of Miles, Huberman, and Saldaña with source, technique, and time triangulation. The findings indicate that Soundtrap reduced hardware specification and software licensing constraints, as it can be accessed flexibly from various devices. All 37 students produced a digital music project covering recording, virtual instrument arrangement, editing, mixing, and exporting, and [XX]% of the surveyed students agreed that the platform was easy to use. Three themes emerged from the interviews: flexible access beyond laboratory hours, collaborative project development and feedback, and technical constraints related to internet stability and the free version. These findings suggest that cloud-based DAW platforms can complement, rather than replace, laboratory-based DAW instruction, particularly for students with varying levels of technological proficiency.

Abstract

This study aims to develop and evaluate a web-based university course timetabling system that hybridizes a Genetic Algorithm (GA) with DSATUR graph-coloring seeding, and to quantify the separate effects of room-type constraints and DSATUR seeding on hard-constraint satisfaction and convergence. The system was developed using the 4D model (Define, Design, Develop, Disseminate) and implemented in the CodeIgniter framework. Real data from the odd semester of the 2025/2026 academic year of the Visual Communication Design Study Program, Universitas Negeri Padang, were used, comprising 87 class sections, 26 courses, 16 lecturers, 12 theory rooms, and 6 practicum studios. A conflict was operationally defined as a lecturer or a room assigned to more than one class section in the same time slot, and a run was successful when it reached the maximum fitness of 87 with zero conflicts. Three stages were compared over ten independent runs each: a basic GA (Stage 1), a GA with room-type separation (Stage 2), and a GA with room-type separation and a 10% DSATUR-seeded initial population (Stage 3). Differences were tested using Fisher’s exact test and Welch’s t-test, with Cohen’s d as the effect size. Room-type separation increased the success rate from 10% to 100% (p < 0.001) and reduced the mean convergence generation from 405.9 to 174.4 (p < 0.001). DSATUR seeding further reduced the mean convergence generation by 15.5% (from 174.4 to 147.3) and the mean computation time by 9.8% (from 71.16 s to 64.22 s); however, these reductions were not statistically significant with ten runs (p = 0.372 and p = 0.132). The findings show that domain-specific constraint modeling is the decisive factor for feasibility, whereas heuristic seeding provides a moderate efficiency gain. The final system produced conflict-free timetables in every run and reduced a manual process of several days to about one minute of computation.
