Geometric configuration and reference-point distance as determinants of resection accuracy: Evidence from student surveying calculations
type: item
description: This study investigates how geometric configuration and reference-point distance affect the accuracy of resection in student surveying calculations, using RTK GNSS coordinates as the reference benchmark. Although resection remains a fundamental method in surveying education and practice, its accuracy is highly sensitive to network geometry and field setup quality, while empirical evidence from student calculation contexts remains limited. To address this gap, the study employed an empirical accuracy-assessment design based on campus field-practicum data generated by student teams using total station observations and RTK GNSS control coordinates. The analysis compared resection-derived and RTK-based coordinates through component-wise discrepancies and horizontal positional error and then interpreted the results in relation to the geometric properties of each resection configuration. The findings show that most observed configurations produced relatively small horizontal errors, indicating that resection can yield acceptable station coordinates in educational field settings. However, accuracy varied considerably across cases. Configurations characterized by balanced point distribution, moderate station angles, and proportionate reference-point distances generally produced more reliable results, whereas stretched or near-collinear configurations were associated with weaker accuracy. At the same time, the results indicate that favorable geometry alone does not guarantee strong performance, because observational execution also remains influential. The study contributes to surveying education by reframing resection as an empirical accuracy problem shaped by both geometric design and field practice.

Geometric configuration and reference-point distance as determinants of resection accuracy: Evidence from student surveying calculations
type: item
description: This study examined the effectiveness of video tutorial–based learning media in improving students’ mastery of horizontal-position Shielded Metal Arc Welding (SMAW) in a technical and vocational education and training (TVET) context. The study responded to the limited evidence on position-specific digital instructional media in welding education, particularly for horizontal-position SMAW practice, which requires precise control of movement, angle, and bead formation. A pre-experimental one-group pretest-posttest design was employed involving 30 Grade XI students in the Mechanical Engineering program at SMKN 1 Sumatera Barat. Data were collected using a validated 30-item performance assessment covering preparation, process, and final weld quality, and were analyzed using descriptive statistics and a paired-samples t-test in IBM SPSS Statistics. The results showed a substantial improvement in students’ performance after the intervention. The mean score increased from 47.57 in the pre-test to 81.70 in the post-test, with a mean gain of 34.13 points. The paired-samples t-test revealed a statistically significant difference, t(29) = 15.25, p < 0.001, and the effect size was very large (d = 2.78). These findings indicate that video tutorial–based media can serve as an effective, low-cost, and scalable instructional tool for procedural welding skills. The study contributes to digital pedagogy in TVET by highlighting the importance of pedagogical fit in technology-supported practical instruction.

The effect of compaction method on the compressive strength and porosity of normal concrete
type: item
description: This study investigates how community-like compaction practices affect density, porosity, and compressive strength of normal concrete across different workability levels. A factorial laboratory experiment (4 compaction methods × 3 slump targets) was conducted using 150×300 mm cylinders (n=72; six replicates per group). Concrete was proportioned to SNI 03-2834-2000; control compaction followed SNI 2493:2011; 28-day strength was tested per SNI 1974:2011; porosity was measured using an ASTM C642-based procedure. Slump was set at 5, 7, and 11 cm by varying water content. Fresh mass decreased as compaction became less effective, indicating lower achieved density and greater entrapped air: compared with SK, hammer vibration (SH) and no compaction (SP) were ~7–9% lighter. Porosity increased markedly under inadequate compaction, with SP reaching 22.36–26.81% versus 10.16–14.22% for SK. Compressive strength followed the same ordering: SK achieved 18.99–22.94 MPa, while SH and SP dropped to 9.90–13.93 MPa and 8.49–13.35 MPa, respectively, with losses up to ~58% relative to SK depending on slump. Overall, slump alone did not guarantee performance when compaction was poor. Rodding (SR) provided intermediate results, maintaining mass close to SK and limiting strength loss compared with SH/SP. An inverse porosity–strength relationship was observed across slumps.

Implementing an Android Facial-biometric attendance system in a resource-constrained school: Validity, practicality, and effectiveness evidence
type: item
description: This study designed and evaluated an Android-based e-attendance application integrating facial biometric verification and WhatsApp notifications to address inefficiencies in manual attendance at MTsN 2 Payakumbuh, Indonesia. A design-and-development methodology using the Spiral Software Development Life Cycle (SDLC) was applied from May to November 2025, covering iterative requirements elicitation (observation and semi-structured interviews), planning, risk analysis with UML modelling, engineering, deployment, and customer evaluation. The system comprises a Laravel–MySQL web dashboard for administrators and a Flutter Android application for teachers. Attendance is verified through Face++ facial recognition, while parents receive automated attendance-status messages via a WhatsApp API. Product quality was assessed through expert validity testing (Aiken’s V), user-practicality testing (Kappa Moment), and a one-group pre-test–post-test effectiveness evaluation (normalized gain). Results indicate high validity for both content and construct dimensions (mean = 0.97), very high practicality (κ = 0.91), and very high effectiveness with substantial improvement from pre-test (33.94%) to post-test (95.15%), yielding g = 0.92. These findings suggest the proposed solution is feasible for routine classroom use, improves administrative efficiency and transparency, and strengthens parent–school communication, while highlighting the need for broader trials and stronger long-term biometric governance. The design includes manual status adjustment and report export to Excel, supporting continuity during connectivity fluctuations common in typical resource-limited schools.

Implementation of a WhatsApp-based Canteen Menu Chatbot using TF–IDF and cosine similarity: A case study of employees at Matahari Department Store, Sunrise Mall and Mojokerto
type: item
description: This study addresses the limitations of traditional workplace canteen menu information sharing, such as noticeboards and verbal announcements, which can cause delays in shift-based settings. A WhatsApp-based canteen menu chatbot was designed, implemented, and evaluated for Matahari Department Store Sunrise Mall Mojokerto (Indonesia) using Cosine Similarity for text matching. The system integrates WhatsApp messaging via the WhatsApp API with an application server and an admin web panel built on Laravel–MySQL, enabling the management of daily menus, canteen schedules, FAQ patterns, user access, and conversation logs. User queries and stored question patterns were preprocessed (lowercasing, cleaning, tokenization), vectorized using TF–IDF, and matched using Cosine Similarity with a 0.6 acceptance threshold to route responses into three classes (Static, Menu, or Schedule) or a fallback reply. Functional verification through black-box testing confirmed the correct operation of core modules and end-to-end message handling. Similarity computation was validated against a manual example (0.816 vs. 0.8165). Robustness testing on 50 employee questions (25 standard and 25 informal/misspelled) achieved 92% accuracy (46/50); retrieval effectiveness measured as micro-F1 across the three response classes was approximately 0.95, with four queries treated as unmatched. A baseline comparison showed that Cosine Similarity was more tolerant to paraphrasing than SQL keyword matching. The case study ran from August to November 2025, and conversation logs were used during the maintenance phase to refine FAQ patterns and improve coverage. Overall, the chatbot offers a lightweight and deployable solution for routine, time-sensitive internal information services in retail workplaces.

The effect of computational thinking on cognitive load and problem-solving skills of electrical engineering education students at Universitas Negeri Malang
type: item
description: The rapid development of technology requires prospective teachers to master 21st century skills, particularly problem solving. Students in the Bachelor of Electrical Engineering Education program at Universitas Negeri Malang often experience a high cognitive load due to heavy academic demands and limited computational thinking, which hinder their problem-solving abilities. This study investigates the influence of computational thinking on cognitive load and problem-solving skills. Using a quantitative descriptive design with saturated sampling, 116 students from the 2022–2023 cohorts participated by completing a closed-ended questionnaire. Data were analysed through prerequisite tests, descriptive statistics, and hypothesis testing using MANOVA with SPSS 27. Results show that students with higher computational thinking have lower cognitive load (M = 44.19) and higher problem-solving skills (M = 55.70). Computational thinking significantly affects cognitive load (p < 0.001, η² = 0.415) and problem solving (p = 0.019, η² = 0.067). However, this study is limited to self-reported questionnaire data from a single institution, which may affect the generalizability of the findings. The novelty of this research lies in its simultaneous examination of computational thinking, cognitive load, and problem-solving skills in engineering education, an area that remains underexplored in the Indonesian higher education context. These findings indicate that computational thinking plays a substantial role in reducing cognitive load and improving problem-solving skills, thereby providing valuable insights for curriculum development and instructional design in higher education.

This study investigates the effectiveness of a hybrid motorcycle prototype as an innovative learning media to improve student learning outcomes in vocational automotive education. Employing a pre-experimental one-group pretest-post-test design, the research involved 30 Grade XI Automotive Engineering students at SMK Negeri 1 Cisarua. Participants underwent a pretest, followed by four prototype-based learning sessions, and a post-test. Data were analysed using descriptive statistics, paired-samples t-test, and normalized gain (g). Results demonstrated a substantial improvement in learning outcomes, with the mean score increasing from 58.5 to 82.67 (mean gain = 24.17 points; t(29) = 8.805, p < 0.001; Cohen's d = 1.61), indicating a very large effect size. The normalized gain of 0.55 suggests medium effectiveness based on Hake's classification. Furthermore, 90.0% (27/30) of students achieved scores ≥75 post-intervention, compared to 23.3% (7/30) beforehand. Aligning with Edgar Dale’s Cone of Experience, these findings highlight that direct, hands-on engagement enhances comprehension and retention. The study concludes that hybrid motorcycle prototypes offer a cost-effective, practical, and scalable solution to bridge the theory-practice gap in vocational automotive education, especially in motorcycle-dominant contexts. Recommendations include integrating prototype-based learning into the Merdeka Curriculum and expanding its application to other technical domains.

Comparative simulation analysis of the economics of unit commitment to determine the cost of supplying electricity in simple generating systems in the Bengkulu region
type: item
description: An efficient electrical system is essential to meet the energy needs of the community without incurring high operational costs. This study aims to compare the total operational costs of power plants during three extreme time periods: low load (00:00–05:00), medium load (06:00–18:00), and high load (19:00–23:00), and to determine the most efficient combination of power plants using the Unit Commitment (UC) method based on priority list techniques. The study was conducted on the Bengkulu regional power system with the assumption of zero startup costs due to data limitations. Simulation results show that coal-fired power plants (IPP), hydroelectric power plants, and micro-hydro power plants serve as the base load power plants that are always active due to their low operational costs, while diesel power plants are only used as supplements when load exceeds the capacity of the main power plants. The lowest total operational cost occurs during low-load periods at Rp 40,936,446/hour, while the highest cost occurs during peak-load periods at Rp 65,040,329/hour. This finding confirms that optimizing the combination of power plants based on cost efficiency can significantly reduce operational expenses. In the future, it is expected that the electricity system can adopt smart grid technology to reduce, even eliminate, the use of inefficient diesel power plants.

type: item
description: Entrepreneurship is increasingly seen as an important strategy in reducing unemployment among college graduates and promoting economic resilience. This study aims to examine the predictive role of self-efficacy an individual's belief in their ability to complete a specific task in shaping entrepreneurial interest among university students. Self-efficacy is believed to influence how individuals perceive opportunities and challenges in starting a business, thereby playing a central role in entrepreneurial motivation. A descriptive quantitative approach was used in this study, with data collected through a structured questionnaire distributed to 348 students from nine faculties at the University of Padang. The questionnaire was designed using a Likert scale to measure levels of self-efficacy and interest in entrepreneurship. Data analysis was conducted using descriptive tests, normality, linearity, homogeneity, and hypothesis testing using Pearson's correlation. The results of the study showed a positive and significant relationship between self-efficacy and entrepreneurial interest (significance value= 0.012), with a Pearson correlation coefficient of 0.113, indicating a moderate relationship. Most students demonstrated relatively low levels of self-efficacy and interest in entrepreneurship, but students with high self-efficacy tended to have greater interest in entrepreneurship. These findings emphasize the importance of integrating self-confidence building into university entrepreneurship programs to enhance students' readiness and motivation to enter the entrepreneurial world after graduation.

From passive to critical consumption: The role of educational content in short videos to improve students' critical thinking skills
type: item
description: The engaging and personalized nature from short video makes it quickly popular, yet concerns persist about their potential to diminish critical thinking skills. This study investigates whether short videos with educational content can improve students' critical thinking skills. Using a quasi-experiment method, Thirty-three participants were divided into control and experimental groups, with critical thinking measured using the Holistic Critical Thinking Scoring Rubric (HCTSR) based on essay analysis in pretest and posttest. After administering educational short videos to the experimental group, the results showed that there was an increase in students' critical thinking skills, shown by the result of controlling the pretest variable through the ANCOVA test with a p-value of <0.001. The result highlights the potential of educational short videos as tools for fostering critical thinking by providing interventions which prioritize treatment fidelity through standardized protocols (SOPs) for content delivery, validating assessment tools, and structuring content design. Recommendations for future research include larger sample sizes, repeated data collection at strategic intervals, and rigorous validation of question complexity.

Attitude and its relationship toward information and communication technology competency among vocational engineering students
type: item
description: There are gaps between vocational engineering curricula and industry competency needs, especially in information and communication technology (ICT) competency. However, limited studies have been conducted on factors affecting ICT competency among vocational engineering students, particularly attitudes toward ICT utilization. Thus, this study aims to determine the attitude and the relationship toward ICT competency among vocational engineering students based on the Unified Theory of Acceptance and Use of Technology II (UTAUT II). It was conducted in Higher Education Institutions in West Sumatera, Indonesia. It was a survey study with a quantitative method that used one set of questionnaires to collect data. Respondents are 805, covering first-year and last-year students enrolled in those institutions by purposive sampling. Data were analyzed descriptively for mean and standard deviation, and inferentially by employing Pearson Correlation. Findings showed that the ICT competency among vocational engineering students was lower than their attitude toward ICT utilization. A high attitude only is not enough to support the competency. Thus, this study can be used as a guide by the relevant authorities such as the Ministry of Education Affairs to take action to enhance the ICT competency among vocational engineering students from other aspects.

Revolutionizing polymethyl methacrylate toughness: Achieving 190% improvement with nanocellulose reinforcement while maintaining optical clarity
type: item
description: Polymethyl methacrylate (PMMA) is widely used in applications requiring high transparency and durability, such as optical lenses and protective coatings. However, its inherent brittleness limits its application in high-impact environments. This study investigates the incorporation of cellulose nanocrystals (CNCs) into PMMA to significantly enhance its toughness without compromising its optical clarity. By reinforcing PMMA with CNCs, the nanocomposites exhibited a remarkable 190% increase in toughness while maintaining 90% optical transparency. The innovation lies in achieving a balance between toughness and transparency through controlled CNC dispersion within the PMMA matrix, which minimizes excessive bonding that could lead to brittleness. Proper CNC dispersion was achieved through in-situ polymerization, allowing the nanocrystals to interact with the polymer matrix through van der Waals forces rather than covalent bonds. This approach reduces stress concentration and mitigates the formation of defects in the polymer matrix, ultimately leading to a tougher, more flexible material. In addition to enhancing mechanical properties, this study underscores the importance of controlling CNC content to preserve the intrinsic optical transparency of PMMA. These findings open new possibilities for CNC-reinforced PMMA in advanced applications that demand high mechanical performance coupled with excellent optical properties, extending its use in fields such as medical devices, protective coatings, and transparent structural materials.

Modified sorbents based on natural mineral and its mechanical properties
type: item
description: The use of modified sorbents based on natural minerals, widely distributed in Kazakhstan, is a promising direction. This direction is related to the development of domestic ion-exchange materials. The republic lacks its own production of synthetic sorbents. The environmental situation in the regions of uranium ore mining and processing is also important. Moreover, the application of synthetic sorbents is not always justified due to their high cost, while the use of natural sorbents is limited by their low sorption capacity. The development of modified ion-exchange materials based on a combination of these is a pressing issue for various industries. Research has been conducted on the choice of modification methods for natural sorbents and the evaluation of their sorption capacity after modification. The modification of natural minerals zeolite and shungite using the "solid-phase extractants" method was carried out in two stages. At the first stage, the modification was performed with organic extractants and compositions based on them, and at the second stage with phosphoric acid in combination with polyacrylamide. The natural sorbents used were zeolite from the Kusmuryn deposit and shungite from the Koksu deposit, following preliminary flotation. The mechanical strength of sorbents modified by different methods was compared with the original ion-exchange materials. Studies of the sorption process have shown that the best results for uranium sorption were obtained with modified sorbents: zeolite modified with a mixture of extractants Di-2-Ethylhexyl phosphoric acid (Di-2-EHPA), Tributyl phosphate (TBP), kerosene, and shungite modified with phosphoric acid in the presence of Polyacrylamide (PAA).
