Abstract

Perkembangan teknologi informasi saat ini menuntut lembaga pendidikan untuk memiliki infrastruktur jaringan yang andal dan terpusat. Namun, SMAN 1 Cisayong masih mengandalkan arsitektur jaringan yang terdesentralisasi tanpa pengelolaan koneksi yang memadai. Hal ini menyebabkan ketidakmerataan dalam pembagian bandwidth, kerentanan terhadap IP conflict, serta inefisiensi karena seringnya dilakukan instalasi ulang secara fisik di laboratorium komputer. Penelitian ini bertujuan untuk merancang dan memvalidasi sebuah arsitektur jaringan komputer terpusat yang menggabungkan teknologi Multi-VLAN, Queue Tree, dan Hotspot guna mengatasi masalah tersebut. Metodologi yang dipakai adalah Network Development Life Cycle yang dimodifikasi menjadi tiga tahap utama, yaitu analisis infrastruktur eksisting, perancangan arsitektur logis, dan simulasi prototype menggunakan Cisco Packet Tracer. Hasil perancangan menunjukkan bahwa segmentasi jaringan ke dalam delapan area VLAN mampu mengisolasi domain siaran logis antar ruangan secara efektif, sementara penerapan Queue Tree dengan metode Per Connection Queue berhasil mendistribusikan total bandwidth sebesar 300 Mbps secara adil berdasarkan hierarki pengguna. Sistem Hotspot juga turut mengamankan pintu gerbang jaringan melalui autentikasi kredensial serta sistem voucher. Validasi fungsional di lingkungan simulasi mengonfirmasi bahwa layanan DHCP berjalan dengan tepat, dan aturan Access Control List yang menerapkan prinsip default deny berhasil memblokir lalu lintas data yang tidak diizinkan tanpa mengganggu akses internet. Kesimpulannya, prototype jaringan terpusat ini telah terbukti valid secara fungsional dan sangat direkomendasikan sebagai cetak biru untuk implementasi di lapangan, dengan saran agar ke depan dilakukan pengujian terhadap parameter Quality of Service.

Abstract

This study addresses the network performance problem at Badan Kesatuan Bangsa dan Politik (Bakesbangpol) Kota Tasikmalaya, where staff devices and public guest devices still operate on the same local network path. The existing architecture forms a flat network with one main switch and one main access point, causing traffic concentration and service degradation when the assembly hall is used for public activities. A simulation-based network engineering approach was applied using Cisco Packet Tracer and the PPDIOO lifecycle to redesign the local architecture without interfering with the production network managed by Diskominfo. The proposed solution applies VLAN segmentation to separate staff and guest traffic, adds a dedicated guest access path, and uses inter-VLAN routing to control communication between segments. Observation results indicate that the internet link capacity was approximately 18.85 Mbps download and 4.81 Mbps upload, while the main issue was distribution failure rather than insufficient bandwidth. Simulation results show that the redesigned network successfully assigns different IP subnets and gateways to guest and staff devices through DHCP, proving that logical separation works according to the design. The redesigned architecture is therefore feasible to reduce bottleneck risk, improve network stability, and strengthen access control in support of SPBE implementation.

Abstract

This study aims to analyze the quality of computer networks at the Tasikmalaya City Health Office using Quality of Service (QoS) parameters and evaluate it based on the TIPHON standard. The problem faced is that the network quality is not yet optimal due to a non-integrated network topology design and uneven distribution of access points. The method used in this study is the Network Development Life Cycle (NDLC). The results show that network quality is not evenly distributed across all locations, where delay and packet loss values at most points fall into good to very good categories, while jitter values show significant variation and fall into poor categories in several locations. Thus, it can be concluded that network problems are influenced by a non-centralized topology design, limited number of access points, and high dependence on wireless network usage, therefore improvements in network distribution and a more optimal network topology design are required.
