Abstract

Computer Based Test (CBT) requires robust, stable, and user-friendly network infrastructure. At SMKN 1 Negerikaton, students still access CBT using numeric IP addresses, complicating use and risking errors during simultaneous tests. Furthermore, the school uses four identical servers, resulting in excessive electricity consumption, management complexity, and inefficient hardware use. This study aims to develop a local DNS Server on Debian 12 to allow students to access CBT using a human-readable domain name, improving user experience while optimizing infrastructure. The research employs the Network Development Life Cycle (NDLC), including analysis, design, simulation with VirtualBox and GNS3, implementation of BIND9 on Debian, and monitoring and management. Results show DNS resolution times improve from 200–400 ms to <50 ms. Server infrastructure was consolidated from four machines into one physical server running multiple virtual machines for DNS and CBT services. Mikrotik routers manage DHCP and NAT, and switches were upgraded to Gigabit Ethernet to handle 140 simultaneous clients effectively. This approach is low-cost, open-source, and highly effective in supporting large-scale CBT in schools. The research demonstrates a practical and replicable method for other schools seeking to modernize CBT delivery with limited budgets.

Abstract

Sentra Pelayanan Kepolisian Terpadu (SPKT) merupakan garda terdepan dalam memberikan pelayanankepada masyarakat di lingkungan kepolisian. Polsek Kawasan Pelabuhan Panjang sebagai bagian dariPolresta Bandar Lampung memiliki peran penting dalam menangani berbagai laporan masyarakat secaracepat dan akurat. Namun, sistem pencatatan laporan yang masih bersifat manual menyebabkan beberapakendala, seperti kurang efisiennya proses pencatatan, keterbatasan pencarian data, dan risiko kehilangandata. Skripsi ini merancang dan mengembangkan sistem informasi SPKT berbasis web untuk mendukungpelayanan kepolisian yang lebih modern, cepat, dan akuntabel. Metode pengembangan sistemmenggunakan model Waterfall yang mencakup tahap analisis, perancangan, implementasi, dan pengujian.Sistem yang dibangun mencakup fitur pelaporan kejadian, pencatatan data pelapor dan terlapor, sertapencetakan dokumen laporan. Hasil pengujian menunjukkan bahwa sistem ini mampu meningkatkankecepatan dan ketepatan dalam pengelolaan data laporan, serta mempermudah pihak kepolisian dalammendokumentasikan aktivitas pelayanan. Dengan penerapan sistem informasi ini, diharapkan pelayananSPKT Polsek Kawasan Pelabuhan Panjang menjadi lebih efektif dan responsif terhadap kebutuhanmasyarakat.
