ed on the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to evaluate and map student career readiness. The study uses 20 student samples and five assessment criteria: field-specific competence (C1), internship experience (C2), communication skills (C3), digital literacy (C4), and English language proficiency (C5). Each criterion is assigned a weight based on its relative importance. The TOPSIS method involves decision matrix construction, normalization, weighted normalization, determination of positive and negative ideal solutions, distance calculation, and preference value calculation. The results show that Y11 achieved the highest preference value of 0.8296, followed by Y6 (0.7951), Y19 (0.7274), Y5 (0.7116), and Y2 (0.6999), while Y9 obtained the lowest preference value of 0.3112. Based on the classification results, 1 student (5%) was categorized as Highly Ready, 5 students (25%) as Ready, 12 students (60%) as Moderately Ready, and 2 students (10%) as Not Ready. These findings demonstrate that TOPSIS can effectively rank and classify student career readiness based on multiple assessment criteria. The proposed system can support higher education institutions in identifying students’ readiness levels and developing more objective, targeted, and data-driven career development strategies.
Abstract:Course timetable preparation in the Information Technology Study Program at Universitas PGRI Sumatera Barat is still performed in spreadsheets, typically requires three to five days, and can produce instructor, class, or…
room conflicts. This study develops a web-based scheduling information system that centralizes timetable data, detects collisions automatically, and offers alternatives with support from the Google Gemini API. Development followed the Waterfall System Development Life Cycle, comprising requirements analysis, design, implementation, testing, deployment, and maintenance. The application was built with PHP, Laravel, and MySQL. A deterministic rule identifies overlapping allocations involving the same instructor, class, or room on the same day. Gemini is used only to rank and explain feasible candidates; the application revalidates each recommendation, and the Study Program Secretary retains final approval. Black-box testing of ten functions achieved a 100% success rate. Beta testing produced an average score of 89.22% from three experts and 89.79% from two users, with both results classified as Very Good. The findings indicate that the system is highly feasible for integrated course timetable preparation and administration.
Abstract:The implementation of examinations at SMA Negeri 7 Sarolangun previously encountered operational challenges due to an unintegrated workflow, where exam authoring was conducted via Google Forms and exam delivery relied on…
an Android-based third-party application paired with a custom keyboard. This workflow caused severe device incompatibility, system crashes, and manual score recapitulation delays lasting up to one week. This research aims to design and develop an integrated web-based examination application utilizing the Django framework under the Rapid Application Development (RAD) model to support Midterm (PTS) and Final (PAS) semester exams. The application features master data management, manual question authoring and bulk imports via Excel, token-protected scheduling, asynchronous AJAX auto-saving on computer-based test (CBT) sheets, live proctoring controls, auto-grading, score visibility authorization (Hide Score), and dynamic class-filtered report exports in Excel and PDF formats. System evaluation was conducted through Alpha testing (White Box and Black Box testing) and Beta testing (ISO/IEC 25010:2011 quality evaluation by system experts and End-User Computing Satisfaction/EUCS by end-users). Alpha testing verified that all 29 independent logic paths in White Box testing executed without branching errors and Black Box testing achieved 100% validity across 13 functional modules. Beta testing with 2 system experts yielded an average score of 98.25% (Very Good), and end-user testing involving 27 respondents achieved an average satisfaction score of 84.75% (Very Good). Thus, the developed system is highly feasible, reliable, and effective for school examination operations.
Abstract:Village infrastructure development planning often faces challenges in determining priorities due to limited budget allocations and assessment mechanisms that still tend to be subjective. This study aims to build an objective,…
tive, transparent, and measurable Decision Support System (DSS) to determine the priority order of infrastructure development proposals in Asam Jawa Village, Torgamba District. The applied solution integrates the Rank Order Centroid (ROC) method to calculate criteria weighting based on relative importance, and the Simple Additive Weighting (SAW) method to process the alternative ranking calculation. The evaluation was conducted on 23 physical infrastructure proposals using four main criteria: urgency level (C1), physical condition (C2), benefits (C3), and population size (C4). The results indicate that alternative A4 (Construction of Borehole Well and Public Toilet at Field) and alternative A18 (Sejahtera Street Concrete Cast) achieved the highest preference score of 1.000000, followed by other infrastructure proposals in a structured manner. The combined use of ROC and SAW methods is proven to be effective and consistent in generating accurate rural development priority rankings. The integration of these two methods facilitates village government officials in making accountable decisions while minimizing cognitive bias risks in optimizing development budget allocation.
Abstract:This study developed and evaluated a standalone, non-intrusive radio frequency identification (RFID)-based elevator access control system for a four-story residential building. The system used an Arduino Uno, an MFRC522…
RFID reader, and relay interfaces to regulate access to Floors 2, 3, and 4. Authorized card identifiers and floor permissions were stored locally, enabling offline operation without an external database or network connection. The relays interfaced only with the elevator push-button circuits and did not modify the original controller, motor drive, door mechanism, or safety system. Performance was evaluated using 47 registered cards and three unregistered cards, with each card tested 50 times, producing 2,500 authentication trials. Under the tested conditions, all registered cards were correctly authenticated according to their assigned floor permissions, while all unregistered cards were rejected. The system achieved 100% authentication accuracy, 100% correct relay activation, and 100% unauthorized-card rejection. Stable card detection was obtained at distances of up to approximately 1 cm. The first-floor button remained independent of the RFID module to preserve minimum accessibility during module failure. The proposed system provides a practical and low-cost retrofit solution for floor-specific elevator access control in small residential buildings.
Abstract:This study examines how leadership and work-life balance influence employee performance directly and indirectly through employee engagement at the Fisheries Service of Central Maluku Regency. A descriptive quantitative,…
causal-correlational design was applied to the entire population of 49 employees using total sampling. Data were analyzed through descriptive statistics, path analysis, and Sobel tests to estimate direct, indirect, and mediating effects. The findings show that leadership significantly affects employee engagement (beta = 0.582; p < 0.001), while work-life balance also has a significant, although smaller, effect on engagement (beta = 0.129; p = 0.005). Employee engagement strongly affects performance (beta = 0.942; p < 0.001). In contrast, the direct effects of leadership (beta = 0.034; p = 0.613) and work-life balance (beta = -0.008; p = 0.756) on performance are not significant. Sobel testing confirms that employee engagement mediates the effect of leadership on performance (p = 0.00015) and the effect of work-life balance on performance (p = 0.03). The model explains 92.4% of the variance in performance. The study's novelty lies in demonstrating, within a local public-sector context, that leadership and work-life balance improve performance primarily by strengthening employee engagement rather than through direct effects. These findings imply that public organizations should prioritize engagement-oriented leadership and work-life policies to achieve sustainable employee performance.
Abstract:This study aims to analyze the influence of work skills, work discipline, and work motivation on employee performance with a reward scheme as a moderation variable in BU17 employees of PT. Tjiwi Chemical Paper Factory, Tbk.…
bk. The research uses an explanatory quantitative approach using the Structural Equation Modeling–Partial Least Square (SEM-PLS) method. The research population amounted to 379 employees with a sample of 192 respondents selected using purposive sampling techniques. Data collection was carried out through a questionnaire based on the Likert scale and analyzed using SmartPLS 3.0. The results of the study show that work skills, work discipline, and work motivation have a positive and significant effect on employee performance. In addition, reward schemes have been shown to be able to moderate the relationship between job skills, work discipline, and work motivation to employee performance significantly. These findings suggest that rewards not only serve as a form of organizational reward, but also as a work behavior reinforcer that is able to increase the effectiveness of individual contributions to performance achievement. This research provides theoretical implications in the development of the human resource management literature based on reinforcement theory and human capital theory, as well as practical implications for companies in designing a fair, transparent, and performance-based reward system to increase organizational productivity and effectiveness.
Abstract:Steamed sponge cake (bolu kukus) is a widely consumed traditional snack in Indonesia; however, its reliance on refined wheat flour limits its micronutrient and dietary fiber density. Incorporating composite flours from indigenous…
ndigenous crops, such as tropical pumpkin (Cucurbita moschata) and green pea (Vigna radiata L.), offers a promising strategy for nutritional fortification and dietary diversification. This study aimed to evaluate the proximate composition, sensory acceptability, statistical differences, and production cost feasibility of steamed sponge cakes formulated with varying proportions of pumpkin and green pea flours as partial replacements for refined wheat flour. An experimental design was applied using three formulations: AF09 (Control: 100% wheat flour), BW91 (10% pumpkin flour, 20% green pea flour), and CB88 (15% pumpkin flour, 15% green pea flour). Proximate testing measured moisture, ash, protein, fat, crude fiber, and total carbohydrates (by difference). Sensory acceptance (color, aroma, taste, and texture) was evaluated by 50 semi-trained panelists using a hedonic scale. Data were analyzed non-parametrically using Kolmogorov-Smirnov, Kruskal-Wallis, and post-hoc Mann-Whitney tests. All formulations complied with the Indonesian National Standard (SNI 01-3840-1995) for moisture (31.69%–33.74%), total ash (0.66%–1.05%), crude protein (5.80%–6.65%), and crude fat (1.64%–2.82%). Formula CB88 achieved the highest crude fiber content (0.69%) and lower total energy density (269.88 kcal/100 g). Kruskal-Wallis testing indicated statistically significant differences (p<0.05) among formulations for color, taste, and texture, while aroma exhibited no significant variation (p=0.672). Formula CB88 emerged as the optimal treatment, receiving superior sensory acceptance ratings for color (90% liked) and crumb softness (88% liked) driven by natural β-carotene and pectin-moisture gelation. Production cost analysis demonstrated high economic feasibility for CB88 at IDR 3,374 per 55 g serving. Partial substitution with 15% pumpkin flour and 15% green pea flour (Formula CB88) yields a nutrient-dense, fiber-enriched, and cost-effective functional snack suitable for targeted school nutrition and dietary diversification programs.

and practical skills of the residents of Jingkang Village in converting spent coffee grounds into aromatherapy candles and air fresheners based on the principles of the circular economy. The program employed a Participatory Action Research (PAR) approach consisting of problem identification, program planning, training implementation, monitoring and evaluation, and reflection. The activity involved 15 participants, including community members, micro-enterprise actors, and women's community groups. Program effectiveness was evaluated using pre-test and post-test assessments and analysed through a Paired Sample t-test. The results demonstrated that the average participant score increased from 46.70 to 86.00, representing an 84.15% improvement. Statistical analysis confirmed a significant difference between pre-test and post-test scores (p < 0.001). Furthermore, all program success indicators were achieved, including a 100% attendance rate, 100% participant competency in producing the products, a participant satisfaction level of 93.30%, and all products meeting usability standards. The novelty of this program lies in integrating the Participatory Action Research (PAR) approach, circular economy principles, and quantitative statistical evaluation into a community empowerment model utilizing spent coffee grounds as value-added products. This model has strong potential to be replicated in other coffee-producing communities to promote sustainable waste management and local economic development.
