An intelligent decision support system (IDSS) is a decision support system that makes extensive use of artificial intelligence (AI) techniques. Use of AI techniques in management information systems has a long history – indeed terms such as "Knowledge-based systems" (KBS) and "intelligent systems" have been used since the early 1980s to describe components of management systems, but the term "Intelligent decision support system" is thought to originate with Clyde Holsapple and Andrew Whinston in the late 1970s. Examples of specialized intelligent decision support systems include Flexible manufacturing systems (FMS),intelligent marketing decision support systems and medical diagnosis systems. Ideally, an intelligent decision support system should behave like a human consultant: supporting decision makers by gathering and analysing evidence, identifying and diagnosing problems, proposing possible courses of action and evaluating such proposed actions. The aim of the AI techniques embedded in an intelligent decision support system is to enable these tasks to be performed by a computer, while emulating human capabilities as closely as possible.

Abstract

Nutritional problems in Indonesia show a concerning trend, with adult overweight and obesity prevalences reaching 14.4% and 23.4% (2023 Indonesian Health Survey). However, existing mobile nutrition applications commonly rely on static macronutrient ratios, lack transparent decision-making mechanisms, and do not incorporate localized Indonesian food composition data, limiting their practical relevance for Indonesian users. This study aims to develop NutriSee, a mobile application for determining dietary patterns based on Body Mass Index (BMI) classification. The application was built using the Rapid Application Development (RAD) method, Flutter framework, and Firebase Firestore. The system implements BMI calculation (WHO Asia-Pacific standards) alongside Basal Metabolic Rate and Total Daily Energy Expenditure calculations utilizing the Mifflin-St Jeor equation. A rule-based system generates five daily meal recommendations based on users' caloric and macronutrient targets, using the Indonesian Food Composition Table (TKPI 2020) database. Black Box Testing with Boundary Value Analysis and Equivalence Partitioning passed all 33 scenarios. User Acceptance Testing involving 30 respondents yielded "Very Good" acceptance rates of 89.33% for functionality and 84.40% for usability. These findings indicate that NutriSee functions effectively and remains accessible for practical use, enabling Indonesian adults to independently plan and manage their daily dietary intake based on localized food composition data

Abstract

Traditional musical instruments of Papua represent a rich cultural heritage that faces a decline in public awareness due to limited access and physical preservation challenges. Most instruments are stored exclusively in cultural houses (Sanggar) or museums, isolating them from the younger generation who are deeply engaged with modern mobile technologies. This study aimed to develop and evaluate an Augmented Reality (AR)-based cultural preservation medium that improves public access to information on Papuan traditional musical instruments, specifically the Tifa, Tifa Titir, and Gong from the Fakfak region. The novelty of this study lies in its localized integration of three-dimensional visualization, authentic instrument sounds, and contextual cultural information into a mobile AR application designed for indigenous musical heritage preservation. Using a structured Waterfall development approach, cultural data were collected from local cultural custodians and transformed into interactive digital content. The application projects realistic 3D assets, plays authentic instrument sounds, and displays textual cultural information upon scanning unique physical markers. Black-box testing validated that all system features, including marker tracking, audio triggers, and page navigation, functioned successfully across various Android hardware environments. User satisfaction evaluations yielded an overall cumulative usability index of 90.35%, classifying the application as highly effective and user-friendly. This digital intervention bridges the gap between historical preservation and modern education, providing an accessible, interactive, and community-oriented model for cultural digitization and learning

Abstract

Computer keyboards serve as essential input devices that translate user actions into digital signals. One common failure mechanism in keyboard membranes involves broken or degraded circuit traces, which leads to non-functional keys. This study investigates the restoration of such traces using conductive silver paste. An experimental approach was adopted, involving the repair of damaged traces on flexible membrane keyboard PCBs, followed by electrical testing and durability observation. The measurement outcomes indicate that silver paste offers approximately 7% higher electrical conductivity relative to copper, with measured resistivity at 15.87 nΩ·m and thermal conductivity reaching 430 W/m·K. Open circuit conditions (infinite resistance) were successfully restored to functional conductive paths showing 3.5 ± 0.8 Ω resistance after paste application and controlled heat curing. The post-repair resistance represents only a 25% increase compared to the original intact trace value of 2.8 ± 0.5 Ω, which remains well within the acceptable range for digital keyboard applications. This research contributes practical guidance for computer hardware maintenance personnel and researchers focused on input device reliability, while also supporting sustainable practices through repair-based lifecycle extension

Abstract

K-Means is one of the most widely used clustering algorithms because of its simplicity and computational efficiency. However, its performance often decreases when handling non-linear data due to the assumption that all attributes contribute equally to the distance calculation process. This study proposes a Variance-Weighted Distance Metrics K-Means (VWDM-KMeans) method that assigns attribute weights based on variance values to improve clustering quality. The proposed approach consists of Min-Max Normalization, variance calculation, weight generation, and integration of variance-based weights into the distance metric used by K-Means. Experiments were conducted on a non-linear dataset containing 103 records and 3 attributes (x, y, and z) with K = 3 clusters. The generated attribute weights were 0.3207, 0.3342, and 0.3451 for attributes x, y, and z, respectively. The performance of VWDM-KMeans was compared with conventional K-Means and K-Medoids using the number of iterations, Sum of Squared Errors (SSE), and Silhouette Score (SS). The results showed that VWDM-KMeans converged in 5 iterations, compared to 6 iterations for K-Means and 3 iterations for K-Medoids. In terms of cluster compactness, VWDM-KMeans achieved the lowest SSE value of 2.7932, outperforming K-Means (8.2429) and K-Medoids (8.9602). Furthermore, VWDM-KMeans obtained a Silhouette Score of 0.4854, equal to K-Means and higher than K-Medoids (0.4696). These findings demonstrate that incorporating variance-based attribute weighting into the distance calculation process improves cluster compactness while maintaining cluster separation quality and stability. Therefore, VWDM-KMeans can serve as an effective and computationally efficient alternative for clustering non-linear data.

Abstract

Artificial intelligence increasingly transforms military decision-making through autonomous targeting, predictive battlefield analytics, cyber operations, and algorithm-assisted command systems. Although these technologies improve operational speed, they create governance risks when machine-speed decisions exceed human oversight, legal accountability, and escalation control. This study analyzes governance asymmetry in AI-driven autonomous warfare decision support systems and develops an escalation-aware governance framework. A structured qualitative review using transparent search procedures and thematic synthesis was conducted across 33 peer-reviewed and institutional sources on military AI, autonomous weapons, cybersecurity, and AI governance. The synthesis reveals three interconnected governance failures governance asymmetry, symbolic human control, and escalation compression that reinforce one another by weakening accountability, reducing substantive human judgment, and increasing strategic instability. The study proposes a human-centered escalation-aware governance framework integrating eight operational control layers: human authorization checkpoints, explainability, auditability, cybersecurity resilience, cognitive security, escalation-control mechanisms, emergency override, and post-action review. The framework contributes to intelligent decision support literature by translating autonomous warfare risks into embedded governance layers for preserving accountability and strategic stability

Abstract

The selection of outstanding students is an important process in education as it serves as the basis for awarding achievements and motivating students to improve both their academic and non-academic performance. However, the selection process in many schools is still carried out manually, which may lead to subjectivity and a lack of transparency in decision-making. This issue also occurs at SMA Plus Nurul Mubin, creating the need for a Decision Support System (DSS) that can assist the evaluation process in a more objective and systematic manner. This study aims to implement the Weighted Product (WP) method to determine outstanding students based on four criteria: Subject Grades, discipline, attendance, and extracurricular participation. The weight assigned to each criterion was determined based on the school's policies as the basis for the decision-making process. The research employed data collection methods including interviews, observations, and documentation. The collected data were then processed using the Weighted Product (WP) method through weight normalization, vector S calculation, and vector V calculation to obtain the final ranking results. The findings indicate that the Weighted Product (WP) method is capable of providing objective recommendations for outstanding students based on the preference value of each alternative. Based on the calculation results, alternative S3 obtained the highest vector V value of 0.176193538, ranking first as the outstanding student. It was followed by S6 with a value of 0.170283200, S5 with 0.168336098, S2 with 0.166745623, S1 with 0.160578981, and S4 with 0.157862560. These results demonstrate that the Weighted Product (WP) method is capable of producing an objective, effective, and transparent ranking of students based on the predetermined criteria weights. Therefore, the developed system can serve as a recommendation tool for schools to support the outstanding student selection process in a more accurate, structured, and accountable manner

Abstract

The process of selecting outstanding students at MA Badrul Islam Gulung is still done conventionally, mainly by considering report card grades as the key factor, which could lead to subjectivity and be less effective in decision making. This study aims to develop a decision support system for selecting outstanding students using a combination of the Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods. AHP is used to determine the priority weight of each criterion, while SAW is used to rank students based on preference scores. Data was collected through observation, interviews, questionnaires, and literature studies, involving 10 respondents and 5 student alternatives as research subjects. This study uses six assessment criteria: academic grades, non-academic achievements, behavior, discipline, activeness, and memorization of the Qur’an. The research results show that the combination of the AHP and SAW methods can produce a more objective, transparent, and systematic evaluation process. Based on the calculations, alternative A3, named Oktaviana, scored the highest at 0.991 and was chosen as the outstanding student because she had excellent and consistent scores across almost all assessment criteria, especially in academic performance, behavior, and Qur'an memorization. Thus, the decision support system that was developed can help the school determine outstanding students more accurately and efficiently

Abstract

Solar photovoltaic (PV) power plants are increasingly deployed in tropical regions such as Indonesia, yet their performance is often degraded by undetected faults including partial shading, dust accumulation, and module mismatch. This study presents a computational intelligence framework for real-time monitoring and fault diagnosis of grid-connected PV systems from a computer science perspective. The framework consists of three main components: (1) a data acquisition module that simulates 12 months of PV system operation (25 kWp capacity) using meteorological data from Medan, Indonesia, generating 8,760 hourly samples of voltage, current, power, irradiance, and temperature; (2) a machine learning-based fault classifier using Random Forest (RF) and Support Vector Machine (SVM) algorithms to distinguish between four fault types (normal operation, partial shading, dust accumulation, and module mismatch) and one healthy state; and (3) a web-based dashboard built with PHP and MySQL for real-time visualization and alerting. Experimental results show that the Random Forest classifier achieves 97.3% accuracy, 95.8% precision, and 96.2% recall, outperforming SVM (91.6% accuracy). The algorithm detects faults within 1.8 seconds of occurrence, enabling rapid operator response. The proposed system is implemented as an open-source prototype and can be deployed on low-cost hardware (Raspberry Pi 4) with an average response time of 1.8 seconds. The framework is validated using tropical climate data from Medan, Indonesia, addressing a gap in existing PV fault diagnosis research. This research contributes a practical, software-based fault diagnosis tool for PV system operators in tropical environments
