Bandwidth Management Analysis Using Hierarchical Token Bucket (HTB) with MikroTik on the Network of Lisna Clinic YPK PLN Makassar 01

This study aims to implement bandwidth management using the Hierarchical Token Bucket (HTB) method on a MikroTik RB 941 router, utilizing the Simple Queue technique at YPK PLN Clinic Makassar 01. Internet network stability is crucial for several staff members who have experienced issues with poor connectivity. The analysis of internet usage at the clinic reveals the distribution of network access across multiple servers, namely: Cluster 1, which includes the Admin Room, Laboratory, and Pharmacy; Cluster 2, covering the Registration Room, Medical Records Room, and Nurse Station; Cluster 3, comprising the General and Dental Clinics; and Cluster 4, consisting of the Emergency Room and Lobby area. Based on bandwidth requirements analysis, the maximum bandwidth allocation is set as follows: the main server requires 40 Mbps, Cluster 1 receives 10 Mbps, Cluster 2 receives 15 Mbps, Cluster 3 receives 8 Mbps, and Cluster 4 receives 7 Mbps. Performance evaluation was conducted by measuring throughput, delay, jitter, and packet loss. The test results indicate improved computer network performance at YPK PLN Clinic Makassar 01 after implementing the HTB method, with average throughput increasing from 524 Kbps to 1649 Kbps, packet loss remaining at 0.00%, delay decreasing from 122.567 ms to 40.173 ms, and jitter dropping from 122.564 ms to 40.452 ms. These findings demonstrate a significant improvement across all parameters following the application of HTB
