<![CDATA[Abstrak - Kualitas jaringan WiFi merupakan salah satu faktor penting dalam mendukung aktivitas akademik di lingkungan perguruan tinggi. Penelitian ini bertujuan untuk menganalisis kinerja Quality of Service (QoS) pada jaringan WiFi Fakultas Teknik Universitas Serambi Mekkah serta membandingkan kinerja jaringan pada frekuensi 2.4 GHz dan 5 GHz. Parameter yang dianalisis meliputi throughput, delay, jitter, dan packet loss. Pengukuran dilakukan selama tujuh hari pada tiga titik pengujian yang mewakili lantai 1, lantai 2, dan lantai 3 menggunakan metode client-server dengan aplikasi iPerf3. Hasil penelitian menunjukkan bahwa throughput frekuensi 2.4 GHz pada lantai 1, 2, dan 3 masing-masing sebesar 9,97 Mbps, 9,93 Mbps, dan 9,97 Mbps, sedangkan frekuensi 5 GHz sebesar 39,9 Mbps pada seluruh lantai. Nilai delay pada kedua frekuensi sebesar 0 ms. Nilai jitter pada frekuensi 2.4 GHz masing-masing sebesar 4,009 ms, 24,267 ms, dan 1,361 ms, sedangkan pada frekuensi 5 GHz sebesar 0,521 ms, 0,741 ms, dan 0,487 ms. Sementara itu, packet loss pada frekuensi 2.4 GHz masing-masing sebesar 8,9%, 45,3%, dan 0,3%, sedangkan pada frekuensi 5 GHz sebesar 1,4%, 5,0%, dan 0,5%. Berdasarkan evaluasi menggunakan kategori TIPHON, throughput dan delay pada seluruh lokasi termasuk kategori sangat baik. Secara keseluruhan, frekuensi 5 GHz menunjukkan kinerja QoS yang lebih baik dibandingkan frekuensi 2.4 GHz, terutama pada throughput, jitter, dan packet loss, sehingga lebih direkomendasikan untuk mendukung aktivitas akademik di lingkungan Fakultas Teknik Universitas Serambi Mekkah.

This study aims to analyze the Quality of Service (QoS) performance of the WiFi network at the Faculty of Engineering, Universitas Serambi Mekkah, and to compare network performance between the 2.4 GHz and 5 GHz frequencies. The analyzed parameters include throughput, delay, jitter, and packet loss. Measurements were conducted for seven days at three test points representing the first, second, and third floors using a client-server method with iPerf3. The results showed that the throughput values of the 2.4 GHz frequency on the first, second, and third floors were 9.97 Mbps, 9.93 Mbps, and 9.97 Mbps, respectively, while the 5 GHz frequency achieved 39.9 Mbps on all floors. The delay value for both frequencies was 0 ms. The jitter values for 2.4 GHz were 4.009 ms, 24.267 ms, and 1.361 ms, while the 5 GHz frequency recorded 0.521 ms, 0.741 ms, and 0.487 ms on the first, second, and third floors, respectively. Meanwhile, packet loss on the 2.4 GHz frequency was 8.9%, 45.3%, and 0.3%, while the 5 GHz frequency recorded 1.4%, 5.0%, and 0.5%, respectively. Based on the TIPHON evaluation, throughput and delay at all test locations were classified as very good. Overall, the 5 GHz frequency demonstrated better QoS performance than the 2.4 GHz frequency, particularly in terms of throughput, jitter, and packet loss, making it more recommended for supporting academic activities at the Faculty of Engineering, Universitas Serambi Mekkah.
