Abstract

Network optimization is one of the important aspects that aims to improve the performance, efficiency and reliability of network systems and security on the network, but if the optimization is not carried out effectively it will pose a security threat to the network, one of the real threats is DdoS Attack, DdoS attack is a dangerous attack because this attack can paralyze the network server,  Therefore, optimization needs to be carried out in the KP Room in order to avoid the threat of DdoS attacks, so the initial stage of this research will test the network to find out how optimal the network is in the KP room so that optimization is needed. The research method used is NSIT, which includes collection, examination, analysis, and reporting, the results after the research is carried out where, on the network in the kp room after testing at the examination stage and then by identifying the test results, it can be concluded that the network is not optimal enough against DdoS attacks and connection type attacks which, The optimization step taken is to apply a Tarpit firewall on the router. The implementation of Tarpit Firewall successfully overcomes DdoS attacks by slowing down incoming connections and stopping attacks, thereby improving network security from Port Scanning, DDoS, and Brute force attacks.

Abstract

The IT services at PSP Pusri Building are equipped with adequate internet network facilities. However, the distribution of bandwidth across the network is uneven, which leads to bandwidth contention among users and consequently slows down internet connections. This issue arises due to the absence of specific upload and download limits for each room, which affects network stability. Managing upload and download speeds is crucial for efficient data transmission, and bandwidth management is needed to address this problem. This study employs an action research methodology, which includes the stages of Diagnosis, Action Planning, Action Taking, Evaluating, and Specifying Learning. The research focuses on improving network performance by implementing bandwidth management. The Per Connection Queue (PCQ) tree and queue techniques are applied to organize data flow based on priority, ensuring better distribution of bandwidth across all rooms. The results of simulations conducted during the bandwidth management application show significant improvement. The implementation effectively reduces the congestion issues in each room by providing an equal distribution of bandwidth. By using these management techniques, the IT services in the PSP Pusri Building can ensure a more stable and efficient network, improving the overall internet experience for users. This approach not only resolves existing bandwidth issues but also serves as a model for future network improvements. The study highlights the importance of careful bandwidth management in maintaining optimal network performance, especially in environments with multiple users and varying data demands.

Abstract

This study evaluates user experience (UX) on the South Sumatra Province Goods and Services Procurement Bureau (PBJ) website using Jakob Nielsen’s Heuristic Evaluation to identify usability barriers affecting e-government transparency and accountability. As public procurement increasingly relies on digital platforms, preliminary assessments revealed critical issues including unintuitive navigation, limited system feedback, and inadequate user guidance that risk undermining public trust. The evaluation employed a 30-item Likert-scale questionnaire aligned with ten heuristic principles and was conducted by expert evaluators. The results show an overall usability index of 81, classified as excellent, with strong performance in consistency and standards (92 percent) and aesthetic and minimalist design (88 percent). Nevertheless, lower scores emerged in help and documentation (69 percent) and error prevention (78 percent), indicating priority areas for improvement. The findings confirm that usability heuristics function as governance enablers rather than purely technical attributes. Improved visibility of system status and effective error recovery mechanisms enhance procurement oversight and are associated with a 20 to 30 percent reduction in vendor drop-off rates. Contextual tooltips and guidance further strengthen accountability in high-value public tenders. The study recommends simplifying navigation structures, strengthening form validation, and implementing searchable frequently asked questions for sustainable provincial e-government implementation initiatives.
