Abstract

PLN Customer Service Unit (ULP) Banjarbaru, through its Energy Transaction Division (TE), is responsible for processing meter activation data and energy transaction calculations. Currently, the process of combining siaga reports and DILL data is performed manually, which is time-consuming and prone to calculation inaccuracies for additional charges. To address this issue, this study aims to design and develop a Web-Based Meter Activation Data Management and Energy Transaction Information System to enhance efficiency, accuracy, and speed in data management. The system development method used is the Waterfall model, consisting of system analysis, design, coding, and testing stages using the blackbox testing method. The system is designed using an Entity Relationship Diagram (ERD), Data Flow Diagram (DFD), and Flowchart, and is built with PHP, HTML, MySQL database, and the CodeIgniter 4 (CI4) framework. Testing results show that the system performs as expected, assisting staff in recording, managing, and reporting meter activation data and energy transaction calculations more efficiently and accurately.

Abstract

The rapid development of information technology requires digital service systems to have high performance and optimal availability. One of the main challenges in managing web-based services is the system's ability to deal with an unpredictable surge in the number of users. If not anticipated, this can cause a decrease in performance and even detrimental downtime. This study aims to analyze and implement the concept of auto scaling and load balancing in an effort to improve the performance and availability of web-based services. Auto scaling functions to automatically adjust the number of server resources according to workload needs, while load balancing plays a role in distributing network traffic evenly to several servers. The research method used is an experiment, by implementing and testing service performance before and after the implementation of auto scaling and load balancing. The test results show that the combination of the two technologies is able to increase the speed of service response, reduce server load, and maintain optimal service availability. This research is expected to be a reference in the development of reliable and efficient cloud-based systems.

Abstract

Decision Support Systems (DSS) play a crucial role in assisting decision-makers by analyzing large and complex datasets to generate actionable insights. The core performance of a DSS relies heavily on the computational algorithms embedded within its structure, which are responsible for data processing, pattern recognition, and prediction. This study aims to evaluate the effectiveness of three commonly used algorithms Decision Tree (C4.5), Naive Bayes, and K-Nearest Neighbor (K-NN) in supporting decision-making processes using healthcare-related data. The analysis focuses on three performance metrics: classification accuracy, computational speed, and memory usage. A benchmark dataset on heart disease from the UCI Machine Learning Repository was utilized for empirical testing. Results indicate that the Decision Tree algorithm achieved the highest accuracy (92%) and interpretability, making it well-suited for transparent decision-making contexts. Naive Bayes demonstrated the fastest processing time and lowest memory consumption, making it ideal for real-time or resource-constrained systems. Meanwhile, K-NN showed moderate performance but was sensitive to parameter tuning and data volume. These findings suggest that algorithm selection should be aligned with system requirements and resource availability. The study contributes to the development of more efficient and tailored decision support systems by providing empirical evidence of algorithmic strengths and limitations across multiple evaluation dimensions.
