Abstract

The selection process for Kartu Indonesia Pintar (KIP) scholarship recipients at the higher education level continues to face several challenges, including subjective assessment, limited transparency, and the suboptimal use of data-driven decision support systems. This study aims to develop a predictive model for KIP scholarship eligibility at Universitas Almuslim using the XGBoost algorithm integrated with an Explainable Artificial Intelligence (XAI) approach. The dataset employed in this study consists of synthetic data constructed based on official KIP selection parameters, encompassing economic, academic, social, and demographic aspects, thereby ensuring the confidentiality of student data. The research stages include data preprocessing, predictive modeling, policy-based validation, and analysis of prediction results. The XGBoost algorithm is utilized to generate eligibility predictions along with associated probability scores, which are subsequently evaluated to ensure alignment with scholarship selection principles and regulations. The simulation results demonstrate a clear separation between eligible and non-eligible students, with prediction probabilities predominantly concentrated at extreme values, indicating a high level of model confidence. Further analysis reveals that economic indicators and social affirmation variables exert a more dominant influence than academic factors, which function as supporting criteria. These findings indicate that the proposed system is capable of producing stable and consistent predictions while enhancing transparency and accountability in the decision-making process. This study proposes an interpretable scholarship eligibility prediction framework that can be adapted by other higher education institutions as a fair and data-driven decision support system.

Abstract

Penilaian kualitas pencahayaan pada berbagai lingkungan aplikasi, termasuk fasilitas pelayanan kesehatan, sangat bergantung pada sistem monitoring iluminansi yang efektif. Perkembangan sensor cahaya digital yang dikombinasikan dengan platform mikrokontroler telah memungkinkan dilakukannya pengukuran iluminansi secara otomatis dengan biaya yang relatif rendah serta fleksibilitas implementasi sistem. Sensor BH1750 merupakan salah satu sensor cahaya digital yang banyak digunakan dalam sistem monitoring iluminansi; namun, kinerja pengukurannya perlu dievaluasi secara cermat sebelum diterapkan secara luas. Penelitian ini bertujuan untuk mengevaluasi kinerja sensor BH1750 pada sistem monitoring iluminansi berbasis mikrokontroler melalui analisis akurasi, presisi, dan linearitas hasil pengukuran. Pengujian dilakukan pada tiga tingkat iluminansi, yaitu rendah (≈8.000 lux), sedang (≈15.000 lux), dan tinggi (≈22.000 lux), dengan beberapa kali pengulangan pengukuran pada setiap kondisi menggunakan sumber cahaya terkontrol serta instrumen acuan terkalibrasi. Hasil pengujian menunjukkan bahwa sistem monitoring yang dikembangkan memiliki akurasi pengukuran yang baik dengan nilai rata-rata galat persentase kurang dari 3%, presisi yang memadai dengan simpangan baku kurang dari 8%, serta hubungan linear yang sangat kuat terhadap instrumen acuan (R² = 0,9989). Temuan ini menunjukkan bahwa sensor BH1750 dapat diandalkan sebagai bagian dari sistem monitoring iluminansi digital untuk penilaian kualitas pencahayaan pada fasilitas pelayanan kesehatan maupun lingkungan kritikal lainnya.

Abstract

This study designs an integrated relational database for managing student academic activities using a relational approach and the Database Development Life Cycle. The schema integrates study programs, lecturers, students, academic years, courses, curricula, course classes, schedules, study plans (KRS), attendance, grades, academic advising, and student activities. Conceptual modeling was performed using an Entity Relationship Diagram, followed by conversion to a relational schema and normalization through Third Normal Form (3NF). The database prototype consists of 15 principal tables equipped with primary keys, foreign keys, unique constraints, check constraints, and indexes. Verification used synthetic data rather than institutional student records, including 120 students, 12 lecturers, 24 courses, 48 course classes, 720 KRS-detail records, 2,880 attendance records, and 720 grade records. Eight integrity and integrated-query scenarios were executed successfully, including rejection of duplicate student identifiers, prevention of orphan KRS-detail records, restriction of deleting referenced courses, and retrieval of integrated academic histories. The results show that the proposed schema maintains referential consistency and supports cross-module tracing of student academic activities from a single data source. The prototype is intended as a database foundation; production adoption still requires institutional validation, security controls, audit logging, backup and recovery, concurrency testing, and integration mapping.

Abstract

Order cancellation is one of the operational problems in food delivery applications because it can affect service efficiency, restaurant preparation processes, delivery partner productivity, and customer satisfaction. This study aims to analyze order cancellation patterns in food delivery applications using the Apriori algorithm. The research used a quantitative data mining approach with a simulated food delivery transaction dataset consisting of 1,000 records. The dataset included transaction attributes such as order time, restaurant category, payment method, promotion status, delivery distance, delivery fee, estimated waiting time, and order status. The data were processed through cleaning, transformation into categorical itemsets, frequent itemset generation, and association rule formation. The Apriori algorithm was used to identify relationships between transaction attributes and cancelled orders based on support, confidence, and lift values. The results showed that cancellation patterns were strongly associated with long estimated waiting time, far delivery distance, and high delivery fee. The strongest rule was the combination of long waiting time and far delivery distance leading to cancelled orders, with support of 0.120, confidence of 0.750, and lift of 2.50. These findings indicate that the Apriori algorithm can generate interpretable association rules that are useful for identifying high-risk order conditions. The results can support food delivery platform managers in improving service efficiency, reducing cancellation risk, and making data-driven operational decisions.

Abstract

Operational performance assessment is important for technology-based service companies to identify service strengths, weaknesses, and competitiveness. CV Technology Update Computer is a technology service business located in Lae Butar, Gunung Meriah District, Aceh Singkil Regency, Aceh, which provides CCTV supply and installation, computer networking services, laptop sales and services, and technology training. This study aims to apply the Operational Competitiveness Rating Analysis (OCRA) method to assess operational performance and competitiveness at CV Technology Update Computer. This research used a quantitative descriptive case-study design. Four operational service alternatives were evaluated using seven criteria, namely service quality, response time, technical accuracy, operational cost, technician competence, product/service availability, and customer satisfaction with after-sales support. The data were processed by classifying criteria into benefit and cost criteria, calculating preference values, and determining the final OCRA score for each alternative. The results show that CCTV supply and installation obtained the highest final OCRA score, followed by laptop sales and services, computer networking services, and technology training. These findings indicate that CCTV supply and installation is the strongest operational service, while technology training requires further improvement in operational efficiency and supporting facilities. This study contributes by demonstrating that the OCRA method can be used as a systematic and measurable decision-support approach for evaluating operational performance and improving competitiveness in technology-service businesses.

Abstract

Auto Doorsmer 45 is a vehicle washing and care service in Medan with 15 operational employees, one administrator, and one owner. Employee administration and performance appraisal were previously handled manually, causing fragmented records, slow retrieval, and evaluations that depended strongly on managerial observation. This study develops a web-based employee administration information system integrated with a decision support module using Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA). Requirements were collected through observation, interviews, documentation, and literature review, while system development followed the Waterfall model. Fifteen employees were evaluated using five benefit criteria: attendance (0.25), discipline (0.20), responsibility (0.20), work quality (0.20), and teamwork (0.15). The calculation produced the highest optimization value for alternative A9 (0.3002), followed by A7 (0.2899) and A3 (0.2830). The PHP-MySQL implementation integrates employee records, criteria and weights, periodic scores, automated MOORA calculation, ranking, and reports. Black-box testing of ten functional scenarios showed that all specified functions produced the expected outputs. The system therefore provides a more structured, traceable, and consistent appraisal process, while the final managerial decision remains with the business owner.

Abstract

The North Sumatra Regional Revenue Agency (Bapenda) requires timely and reliable information on regional own-source revenue realization to support monitoring, evaluation, and managerial decision making. The source study identifies a reporting process that remains partly manual and insufficiently integrated across work units, creating risks of delayed reporting, inconsistent records, repeated recapitulation, and limited data visualization. This study designs a web-based prototype for regional revenue realization reporting using a prototyping model and Figma. Requirements were elicited through observation, interviews, questionnaires, and document review. The proposed solution models user authentication, target and realization entry, revenue-data management, period and unit filtering, dashboard indicators, graphical analysis, report preview, and print/export functions. Unified Modeling Language (UML) was used to describe use cases, activities, sequences, classes, and the logical relationships required for future implementation. The interface was developed as a high-fidelity prototype so that prospective users could inspect navigation, information hierarchy, and reporting flow before software development. The resulting design integrates target, realization, achievement percentage, remaining target, and report visualization within a coherent workflow. The available source manuscript states that usability evaluation was conducted using the System Usability Scale (SUS), but it does not provide respondent-level data or an aggregate SUS score in the reported results; therefore, this article does not introduce an unsupported numerical claim. The prototype provides a structured design reference for subsequent implementation of a more integrated, transparent, and accountable regional revenue reporting system.

Abstract

Monitoring undergraduate thesis progress at Budi Darma University was supported by administrative records and separate documents, making it difficult to obtain an integrated view of title approval, supervision progress, revisions, and completion status. This study designs and implements a web-based student thesis monitoring application using the Prototyping Model. A qualitative system-development approach was adopted, with requirements collected through an interview with the Head of the Information Systems Study Program, thesis-monitoring documents, and literature review. The prototype was implemented as a functional web application using PHP Native and MySQL. Three role-based users were defined: study-program administrator, supervisor, and student. The application supports title submission and verification, supervisor assignment, student and lecturer data management, thesis-progress recording, supervision notes, revision tracking, detailed monitoring, and monitoring reports. The system was evaluated using Black Box Testing across 13 functional scenarios covering authentication, title submission and approval, rejection, progress entry, supervisor dashboards, supervision notes, revisions, reporting, and logout. All scenarios produced the expected outputs and were classified as valid. The results demonstrate that the implemented prototype satisfies the specified functional requirements and centralizes thesis-monitoring information within a single role-based application. The study is limited to functional testing in a local development environment; performance, security, usability, and production-scale integration with the academic information system remain subjects for further evaluation.

Abstract

Deli Tua District Office in Deli Serdang Regency provides administrative services to the community, but service information, document submission, verification, and status checking are still largely handled through direct interaction at the office. This study designs a UI/UX prototype for an administrative service information system using the Design Thinking approach and Figma. The study applies mixed methods: qualitative data from observation, interviews, and documentation support the Empathize, Define, Ideate, and Prototype stages, while quantitative evaluation is conducted in the Test stage using the System Usability Scale (SUS). The prototype models the service flow from account access and service selection to application submission, document upload, file verification, status monitoring, and service completion. Usability testing involved 30 respondents consisting of 25 community members and five district-office employees. The reported SUS scores ranged from 75 to 100, with an average of 89.25. According to the interpretation used in the study, this score is Acceptable, obtains Grade A, and falls within the Best Imaginable adjective category. The results indicate that the prototype is easy to understand and can serve as a design reference for developing a more integrated, transparent, and user-oriented administrative service system. The study is limited to a high-fidelity Figma prototype and does not implement a database, server, or operational information system.
