Abstract

Accurate and efficient identification of diseases in oil palm leaves is a crucial challenge in maintaining plantation productivity and preventing significant crop losses. Limited access to experts and slow detection in the field are often obstacles. This study aims to develop a palm oil leaf disease classification model using a deep learning approach based on Convolutional Neural Network (CNN) with MobileNetV2 architecture. This model utilizes a transfer learning strategy from pre-trained ImageNet weights and is optimized through a two-phase training strategy on a dataset consisting of 1200 augmented oil palm leaf images, covering four classes, namely Healthy Sample, Fusarium Wilt, Parlatoria Blanchardi, and Rachis Blight. Model testing results show an accuracy of 85% on separate test data. The MobileNetV2 architecture was chosen for its lightweight characteristics, making this model efficient and highly suitable for implementation on mobile devices to assist in rapid disease identification in the field and support decision-making by farmers.

Abstract

PT Palokoto Agro Industri still relies on Microsoft Excel for warehouse record-keeping, which is ineffective for managing large-scale data, prone to errors, and lacks security. The manual stock update process increases workload and reduces data accuracy. Furthermore, the absence of real-time access limits managers in monitoring warehouse activities and making timely decisions. To address these issues, this study developed a web-based Point Of Sales (POS) application. The application was built using the Model-View-Controller (MVC) architecture and the Laravel framework, equipped with features that align with warehouse recording standards, such as managerial access, automatic calculation of incoming and outgoing goods, and fast report generation. This research applied the Research and Development (R&D) method with a prototyping approach. The application was evaluated using the ISO/IEC 25010 standard, and the results showed that it fulfilled all aspects of software quality, including functional suitability, reliability, usability, performance efficiency, maintainability, portability, compatibility, and security. Therefore, the developed application meets the required quality criteria and can serve as a structured solution for warehouse record-keeping at PT Palokoto Agro Industri.

Abstract

The gaming industry has grown rapidly, and one of the key elements in a game is the non-playable character (NPC). Easily predictable NPC behavior often reduces player engagement and satisfaction. Static or unresponsive NPCs tend to create monotonous and less challenging gameplay experiences, ultimately lowering game quality and player interest. This study applies Deep Reinforcement Learning (DRL) using Unity ML-Agents to train agents in a Dodgeball game, enabling them to make adaptive decisions through self-play. A reward system was designed to provide positive feedback for strategic actions, such as picking up and throwing the ball, and penalties for mistakes, such as hitting walls or being hit by the ball. The training results showed a gradual improvement in agent performance, reflected in the increasing and stable cumulative rewards and ELO scores at the end of training. In performance testing, the DRL agent achieved a 66% win rate against the rule-based agent over 50 matches. A user preference test also revealed that 80% of players preferred competing against the DRL agent, with 60% of them considering it more challenging than the rule-based one. These results demonstrate that the DRL agent not only outperforms the rule-based agent but also provides a more dynamic and realistic gameplay experience.

Abstract

Conventional asset management in the IT Division of PT Pertamina Hulu Rokan (PHR) causes data redundancy, manual errors, and slow validation. This study aims to build a multi-platform asset management application to improve recording effectiveness. The system integrates Optical Character Recognition (OCR) for faster asset label identification and Role-Based Access Control (RBAC) for security. Quality testing utilized the ISO/IEC 25010 standard and experimental testing. Results show the application successfully bridges operational needs via a mobile platform (Android) for Field Officers and a desktop platform (Windows) for Admins. ISO/IEC 25010 testing confirmed all main functionalities work validly. Experimental testing proved the application significantly reduces data redundancy and human errors. In conclusion, this multi-platform architecture effectively creates a centralized, accurate, flexible, and real-time asset management ecosystem, outperforming conventional methods.

Abstract

Asset management in information technology at the IT Division of PT Pertamina Hulu Rokan currently faces scalability challenges due to reliance on conventional manual spreadsheet-based processes in managing approximately 30,000 asset data. This condition triggers the risk of human error, data redundancy, and time inefficiency in preparing asset condition recapitulation reports. This study aims to design a website-based Data Summary System that integrates Large Language Models (LLM) technology and spreadsheet data through the use of the Model Context Protocol (MCP) as a form of secure and scalable integration standard. System development was also carried out using a two-iteration prototype method, with Microsoft Azure infrastructure, the FastAPI framework (Python) on the backend side, and React.js on the frontend side. System quality testing was carried out based on the ISO/IEC 25010 standard which covers the eight main characteristics. The test results showed 100% achievement in the functional suitability aspect and the highest rating (Rating A) in the reliability, maintainability, and security aspects using SonarQube analysis. In terms of performance, the system demonstrated high responsiveness with a GTMetrix score of 100% and a usability level of 80.9 (Good category) on the System Usability Scale (SUS). The effectiveness of the system was tested through a One-Group Pretest Posttest experimental design on 8 IT employee respondents. The analysis results showed a good increase in productivity with a Normalized Gain value of 0.91 (High category) and an effectiveness percentage reaching 91.48% (Effective category). Therefore, this Data Summary System has proven successful in minimizing repetitive work steps and increasing accuracy and speed in managing IT assets at PT Pertamina Hulu Rokan.
