In 2019 the number of internet users in Indonesia reached 73.7% of the population as a whole and an increase of 8.9% from the previous year. In State Islamic High School Sidoarjo already provides internet services but existing bandwidth is not distributed evenly between ISP1 and ISP2. In this research, a Load balancing technique is carried out using the Per Connection Classifier (PCC) method. This method divides and classify the data packets to the Gateway connection. QoS Testing was performed using four parameters : Throughput, Jitter, Delay, and Packet Loss are taken the average value by measuring before and after Load balancing. Before Load balancing the uploads and downloads are 19.01 and 19.87 Mbps. From the results of testing the two domain, namely www.google.com and www.youtube.com the Delay was 55 and 39 ms, Jitter was 8 and 17 ms, and Packet Loss was 1% and 19%. Whereas after Load balancing is applied the uploads and downloads are 199.00 and 134.87 Mbps. From the results of testing two domains, the Delay is 21 and 24 ms, both Jitter is 0 ms, and both Packet Loss is 0%.

Tahun 2019 jumlah pengguna internet di Indonesia mencapai 73.7% dari jumlah penduduk seluruhnya dan meningkat 8.9% dari tahun sebelumnya. Pada Madrasah Aliyah Negeri (MAN) Sidoarjo sudah menyediakan layanan internet namun bandwidth yang sudah ada tidak dilakukan pembagian beban secara merata antara ISP1 dan ISP2. Pada penelitian ini, dilakukan teknik Load balancing dengan metode Per Connection Classifier (PCC). Metode ini membagi dan mengelompokkan paket data yang menuju Gateway suatu koneksi. Pengujian QoS dilakukan menggunakan 4 parameter yaitu Throughput, JURNAL TEKNIK INFORMATIKA Homepage : http://journal.uinjkt.ac.id/index.php/ti
