Abstract

Regional expenditure is often considered productive merely because it is recorded as capital spending, although its growth effect depends on targeting, execution timing, asset quality, program complementarity, and local institutional capacity. This study examines how productive expenditure influences regional economic growth in Indonesia using a qualitative library research design and document analysis. The corpus covers scholarly articles, international institutional reports, regulations, Statistics Indonesia growth data, and the national regional-budget posture reported in the Ministry of Finance’s Regional Financial Information System. Evidence was processed through data reduction, thematic coding, cross-source comparison, and explanatory synthesis. Productive expenditure operates through five channels: expanding infrastructure stock, strengthening human capital, reducing transaction costs, improving the productivity of leading sectors, and generating demand multipliers. These effects are conditional and time-lagged. The budgeted capital-spending share ranged from 15.83 to 18.20 percent of total regional expenditure in 2020–2024, while execution levels and timing fluctuated. Economic growth recovered from a 2.07 percent contraction in 2020 to 5.03 percent in 2024, but this aggregate pattern cannot be interpreted as direct causal evidence. The study’s novelty is the Productive Expenditure Transmission Matrix, which integrates allocation, execution, output quality, complementarity, and lagged outcomes. The findings imply that local governments should move from a spending-volume orientation toward portfolio quality and asset functionality.

Abstract

Music Theory instruction in higher education is still often delivered as the transmission of terms, symbols, and rules that are detached from musical experience, and Kolb's four-stage cycle does not specify how musical experience should be sequenced into theoretical concepts. To address this gap, this study modified the Musical Experiential Learning Model (MELM) into a five-stage instructional syntax Musical Experience, Musical Exploration, Musical Conceptualization, Musical Application, and Reflection and Musical Interpretation in which guided exploration and musical application are made explicit stages between experience and reflection. A convergent mixed-methods single-case study with an embedded non-equivalent control group pretest–posttest comparison was conducted with 50 Music Education students enrolled in a Music Theory course at a public university in Indonesia (two intact classes; MELM n = 25, control n = 25). Data were collected through expert validation, classroom observation, task assessment, practicality questionnaires, and pre- and post-tests, and were analysed with descriptive statistics, independent-samples t-tests, Cohen's d, and normalized gain (N-gain). Implementation of the five stages ranged from 92.50% to 96.25%, and student engagement/creativity ranged from 90.60% to 95.75%. Mean achievement in the MELM group rose from 64.92 to 90.72 (N-gain = 0.74), compared with 66.60 to 80.84 in the control group (N-gain = 0.43). The findings indicate that making exploration and application explicit stages helps students connect sound, concept, and practice, and shifts the lecturer's role from information provider to facilitator. Because the classes were not randomly assigned, group differences are interpreted as supporting evidence of association rather than definitive proof of causal effectiveness.

Abstract

Indonesian vocational high school (Sekolah Menengah Kejuruan, SMK) students must master unshielded twisted pair (UTP) cabling, yet pin order, cable types, and connector logic are difficult to visualize, practice time is short, and equipment is often scarce. Grounded in the cognitive theory of multimedia learning and cognitive load theory, this study designed an Android-based virtual laboratory that uses isometric (pseudo-3D) visualization to make the cabling workbench visible on ordinary smartphones. The study addresses a gap in mobile and simulation-based vocational learning research, which has focused on logical network configuration in higher education and has rarely addressed physical cabling at the secondary level. It examined the product's validity, practicality, and preliminary effectiveness as a supplementary medium for UTP cabling concepts. Development followed the 4-D model (define, design, develop, disseminate). Three media and three material experts evaluated the prototype using Aiken's V, and three practitioners and 16 Grade 10 Software and Game Development (PPLG) students rated its practicality. Effectiveness was examined in a pilot study using a pre-experimental one-group pretest–posttest design over eight sessions with a 24-item conceptual test (KR-20 = 0.94). The sample was the entire Grade 10 PPLG class (total sampling); an a priori power analysis showed that 15 participants were needed to detect a large paired effect (dz = 0.80, α = .05, power = .80). Media and material validity were 0.84 and 0.91. Practicality averaged 88.00% (practitioners) and 85.25% (students). Mean scores rose from 62.50 (SD = 12.73) to 85.68 (SD = 8.47), t(15) = 8.14, p < .001, dz = 2.04, ⟨g⟩ = 0.62, and 93.75% of students reached the mastery level. Because no control group was used, this gain indicates an association with the intervention rather than a causal effect, and it may also reflect regular instruction, testing, and maturation. The isometric virtual laboratory is a valid and practical supplementary medium for resource-limited workshops, and controlled studies are needed to establish its effectiveness.

Abstract

This systematized literature review examines how prompt engineering in generative AI (GenAI) has been used to support Project-Based Learning (PjBL) and develops a conceptual framework for Network Programming courses. Following the PRISMA 2020 statement, records published from 2020 to 2026 were retrieved from IEEE Xplore, ScienceDirect, SpringerLink, Google Scholar, and Garuda/Sinta. Of 310 records identified, 242 remained after duplicate removal, 56 were assessed in full text, and 24 studies met the eligibility criteria. Screening decisions were cross-checked by a second reviewer (Cohen's κ = [....]), and study quality was appraised with the Mixed Methods Appraisal Tool (MMAT). Data were analyzed through a hybrid deductive–inductive thematic analysis following Braun and Clarke's six phases: the four research questions served as a priori categories, sub-themes were coded inductively until no new codes emerged, and coding disagreements were resolved by consensus. The results revealed that structured and scaffolded prompting is consistently associated with deeper engagement than unstructured prompting in programming classes, and that GenAI-supported PjBL preserves student autonomy and creativity when AI interaction is embedded in project stages and students must justify their technical decisions. Only one included study addressed computer networking directly. Reported challenges were excessive dependence on AI-produced solutions, shallow learning, and unclear assessment practices. Unlike existing PjBL–GenAI models, which treat AI as a generally available tool, the proposed three-layer framework (competency, scaffolding, and assessment) specifies when and how prompting is taught, constrained, and evaluated across network programming project milestones, and it yields testable propositions for future empirical research.

Abstract

Sumatera merupakan salah satu wilayah dengan aktivitas seismik tertinggi di dunia akibat interaksi konvergen Lempeng Indo-Australia dan Lempeng Eurasia serta keberadaan Sesar Besar Sumatera. Pemahaman terhadap pola kegempaan yang bersifat spatio-temporal menjadi penting sebagai dasar mitigasi bencana. Penelitian ini bertujuan mengidentifikasi pola pengelompokan gempa bumi di Sumatera menggunakan dua algoritma eksplorasi data yang berbeda paradigma, yaitu K-Means (berbasis partisi) dan DBSCAN (berbasis kepadatan). Data yang digunakan adalah katalog gempa United States Geological Survey (USGS) periode Januari 2015 hingga Desember 2025 pada rentang 6,5°LU–6,5°LS dan 94°–107°BT. Setelah praproses dan penerapan ambang kelengkapan magnitudo Mc = 4,0, diperoleh 2.834 kejadian. Lima fitur digunakan sebagai masukan clustering, yaitu lintang, bujur, waktu kejadian, kedalaman, dan magnitudo, yang seluruhnya distandardisasi menggunakan z-score. Jumlah klaster optimal K-Means ditentukan melalui Elbow Method dan Davies–Bouldin Index yang keduanya konvergen pada k = 6, sedangkan parameter DBSCAN ditetapkan melalui grafik k-distance dan penelusuran grid dua dimensi sehingga diperoleh ε = 0,7 dan minPts = 20. Hasil penelitian menunjukkan bahwa K-Means membagi kegempaan Sumatera menjadi enam klaster yang secara konsisten memisahkan segmen utara (Aceh–Simeulue) dan segmen selatan (Bengkulu–Lampung), masing-masing terpecah lagi menjadi dua periode waktu (2015–2020 dan 2020–2025), ditambah satu klaster zona Benioff berkedalaman menengah (rerata 173,7 km) dan satu klaster bermagnitudo tinggi (rerata 5,40). DBSCAN menghasilkan tiga klaster dengan 633 titik (22,3%) diklasifikasikan sebagai noise. Temuan paling menonjol adalah bahwa seluruh 27 gempa bermagnitudo M ≥ 6,0 diklasifikasikan sebagai noise oleh DBSCAN, dan magnitudo titik noise secara signifikan lebih besar dibandingkan titik terklaster (uji Mann–Whitney U, p < 0,001). Nilai Silhouette K-Means (0,260) lebih tinggi dibandingkan DBSCAN (0,214), namun DBSCAN unggul pada Davies–Bouldin Index (0,890 berbanding 1,207). Disimpulkan bahwa kedua metode bersifat komplementer: K-Means efektif untuk segmentasi zona seismik, sedangkan DBSCAN efektif sebagai detektor kejadian anomali yang berpotensi merusak.

Abstract

This study aimed to evaluate haul road geometry on the overburden route of Pit B at a coal mining contractor in Sarolangun, Jambi, Indonesia, and to estimate dump truck cycle time and productivity after geometry correction. An observational–evaluative field design was applied: 48 cross-sections of a 523.82 m road were surveyed with a Total Station and assessed against the Indonesian good mining practice decree, 30 truck trips were timed, and the corrected condition was simulated with a rimpull–resistance model. Only 18.75% of cross-sections met the study design criterion for two-lane width, the steepest descent reached −21.68% against a 12% limit, 45.8% met the cross-slope range on a two-side mean basis, and all curve radii complied. Delays caused by narrow and steep sections made up 69.2% of total delay. Correcting grade and width was predicted to reduce the cycle time from 11.99 to 9.47 minutes (21.0%; 95% bootstrap interval 20.1–21.9%) and to raise truck productivity from 32.06 to 40.60 bank cubic metres per hour (26.6%). If only half of the assumed speed gains were realised, the reduction would fall to 14.7%. These are simulation-based predictions that require field validation after road correction.
