Abstract

The development of information technology has encouraged local governments to provide digital-based public services through official websites. One of these services is the website of the Information and Documentation Management Officer (PPID) of Buleleng Regency which functions as a medium for transparency and public interaction. However, until now there has been no comprehensive testing of the performance, stress levels, and security of all PPID websites in the district. This study aims to evaluate performance, measure stress levels, and identify security gaps on 26 PPID Implementing websites connected to the Main PPID of Buleleng Regency. The method used in this study is Action Research, with testing carried out using three main tools, namely GTmetrix for performance, K6.io for stress testing, and Owasp Zap Scan for security. The test results showed that several websites experienced loading delays, slow server responses during high loads, and security gaps related to SSL and DNS were found. Recommendations for improvement are focused on optimizing performance, increasing server capacity, and tighter security configurations. This study contributes to improving the quality of public information services and supports the realization of a transparent, efficient, and secure government.

Abstract

Optimal access point (AP) placement is essential to ensure uniform and high-quality WiFi signal coverage, particularly in government institutions such as the Department of Education, Youth, and Sports (DISDIKPORA) of Buleleng Regency. This study aims to analyze and compare the effectiveness of Ekahau AI Pro and NetSpot applications in optimizing AP placement. The research methodology integrates Comparative Analysis, Action Research, and Benchmarking, following a structured process consisting of diagnosis, action planning, action taking, evaluation, and learning. Measurements were conducted through active and passive surveys, with cross-validation performed using WiFi Analyzer as a reference tool. Data were collected based on key parameters: Received Signal Strength Indicator (RSSI), blank spot detection, result consistency, and time efficiency. The results indicate that both applications accurately detected all blank spots. However, Ekahau AI Pro demonstrated higher consistency, with only a 1.5 dBm deviation, making it well-suited for long-term planning in complex building environments, despite requiring more time and higher costs. In contrast, NetSpot delivered sufficiently accurate results with an average difference of 6.75 dBm and significantly faster execution time, making it ideal for rapid network audits under limited budgets. Based on the findings, Ekahau AI Pro is recommended for complex environments demanding high accuracy, while NetSpot is more appropriate for fast, dynamic, and cost-effective assessments. This study provides technical recommendations for WiFi network optimization at DISDIKPORA and offers strategic guidance for selecting suitable network mapping tools in similar organizations.

Abstract

This study analyzes user satisfaction with the attendance system of the e‑Ganesha application using the PIECES framework. The research adopts a quantitative descriptive design, collecting data through a Likert scale questionnaire administered to 170 respondents (85 employees and 85 lecturers) at Undiksha, complemented by open-ended questions to capture richer user feedback. Instrument validity was tested using the Pearson Product Moment correlation (all items met r-hitung > r-tabel), and reliability with Cronbach’s Alpha (α = 0.973), indicating excellent internal consistency. Using the Kaplan and Norton classification, overall satisfaction falls in the “satisfied” category. For employees, the highest mean scores are Information and Control & Security (4.49), while the lowest is Economy (4.29); for lecturers, Information is highest (4.62) and Economy is lowest (4.42). Qualitative responses highlight several areas for improvement: slower system speed during peak hours, error messages that are not sufficiently informative, inefficient leave request and approval flows, and limited administrative controls that may allow misuse. The PIECES analysis identifies strengths in informative outputs and data protection, with weaknesses in performance variability and process efficiency; opportunities include workflow automation and monitoring; threats involve declining user trust if friction persists. Recommendations synthesized via SWOT prioritize performance optimization, usability enhancements, streamlined processes, and governance controls. These findings provide actionable guidance for iterative improvements to e‑Ganesha’s attendance module and contribute to the broader literature on satisfaction evaluation in institutional information systems.

Abstract

This study focuses on optimizing the Wi-Fi network coverage area at SMK Negeri 1 Tegalalang through mapping and analysis using the NetSpot application. Stable and evenly distributed internet connectivity is essential to support digital-based learning activities in schools. Preliminary observations revealed several blank spots and uneven signal distribution across classrooms and buildings, indicating the need for improvement in network infrastructure. The research employed an action research approach consisting of four stages: diagnosing, action planning, action taking, and evaluating. Data collection was conducted using both active and passive site surveys, measuring the Received Signal Strength Indicator (RSSI), and generating heatmap visualizations to illustrate signal distribution. The analysis emphasized three main aspects: wall attenuation factors, access point positioning, and potential channel interference that contributed to performance degradation. The findings provide a comprehensive signal coverage map along with recommendations for more strategic placement of access points. These recommendations resulted in improved coverage with a minimum RSSI target of –65 dBm and a service area of at least 80%. The outcomes of this study are expected to serve as a valuable reference for schools in designing and enhancing Wi-Fi infrastructure, ensuring reliable connectivity that supports the implementation of online and blended learning effectively.
