Abstract
This study was conducted to evaluate and improve the performance of the Local Area Network (LAN) at SMK Negeri 17 Jakarta by applying the Quality of Service (QoS) method. The evaluation focused on four key QoS parameters: throughput, packet loss, delay, and jitter. Data collection was carried out using the Wireshark application to capture real-time network traffic over a four-day period across six computer laboratories, during both peak and off-peak hours. The findings reveal that, prior to implementing bandwidth management, there was an imbalance in bandwidth allocation among the laboratories, resulting in degraded network performance during high usage periods. After applying bandwidth control through the Simple Queue feature on a MikroTik router, network performance significantly improved. Throughput values increased, packet loss decreased, and delay and jitter became more stable. These results confirm that the use of QoS methods and bandwidth management can effectively enhance overall network efficiency and stability. This research also provides strategic recommendations for educational institutions in managing their network infrastructure to better support digital activities. Kata kunci: LAN Network, Quality of Service, Wireshark, Bandwidth Management, Simple Queue Penelitian ini dilakukan untuk mengevaluasi dan meningkatkan kinerja jaringan Local Area Network (LAN) di SMK Negeri 17 Jakarta dengan pendekatan Quality of Service (QoS). Evaluasi dilakukan berdasarkan empat parameter utama QoS, yaitu throughput, packet loss, delay, dan jitter. Proses pengumpulan data dilakukan menggunakan aplikasi Wireshark untuk merekam aktivitas lalu lintas jaringan selama empat hari, mencakup enam laboratorium komputer pada waktu penggunaan tinggi (jam sibuk) dan rendah (jam tidak sibuk). Hasil pengamatan menunjukkan bahwa sebelum manajemen bandwidth diterapkan, terdapat ketidakseimbangan dalam distribusi bandwidth antar-laboratorium, yang berdampak pada penurunan kualitas koneksi saat jam sibuk. Setelah konfigurasi manajemen bandwidth diterapkan melalui fitur Simple Queue pada router MikroTik, performa jaringan menunjukkan peningkatan yang signifikan. Nilai throughput meningkat, packet loss menurun, dan delay serta jitter menjadi lebih stabil. Temuan ini mengonfirmasi bahwa penerapan QoS dan pengelolaan bandwidth dapat secara efektif meningkatkan efisiensi dan stabilitas jaringan. Penelitian ini juga memberikan rekomendasi teknis bagi institusi pendidikan dalam mengelola infrastruktur jaringan guna mendukung aktivitas digital secara optimal. Kata kunci: Jaringan LAN, Quality of Service, Wireshark, Manajemen Bandwidth, Simple Queue.
