Abstract

Advancements in information technology require government agencies to maintain secure and stable computer network infrastructures to support operational efficiency. The BKPSDM (Personnel and Human Resources Development Agency) of Central Sumba Regency relies heavily on internet connectivity to manage State Civil Apparatus (ASN) personnel data. However, staff survey results indicate that current internet quality is suboptimal, characterized by frequent slowness and instability caused by the use of bandwidth for non-productive activities, specifically accessing entertainment platforms like YouTube and TikTok. Furthermore, the office WiFi network is vulnerable to unauthorized access, posing a threat to the confidentiality of ASN data. This study aims to implement a network security and bandwidth management system using MikroTik Routerboard devices, grounded in Government Regulation (PP) Number 94 concerning Civil Servant Discipline. The research methodology encompasses network analysis, topology design, implementation, and testing. Implementation results demonstrate that TLS Host-based firewall rules successfully blocked all access to YouTube and TikTok within the ASN work segment. Bandwidth management utilizing the "Simple Queue" feature with a hierarchical method effectively segregated data traffic between the ASN segment and the Public WiFi segment. Quality of Service (QoS) testing revealed significant improvements in network performance: average latency dropped from 185 ms to 32 ms, packet loss decreased from 8.4% to 0.12%, and throughput stabilized at 34.1 Mbps within the ASN segment. This study confirms that integrating firewall capabilities and bandwidth management can optimize data security, stabilize internet connections, and support the enforcement of ASN working-hour discipline at the BKPSDM of Central Sumba Regency.
