Abstract


  1. XYZ has collaborated with PT. Telkom Indonesia (Persero), Tbk to maintain and manage the WLC Autelan devices as one of the backend devices needed to provide wifi.id services. However, during the last 6 months of 2021, Autelan WLC devices have experienced a slight decrease in performance with frequent problems with the device. Data analysis was carried out using the DMAIC method and initial findings showed that from the Pareto diagram it was found that the largest percentage of the type of problem was service restore with a cumulative percentage of 60%. Then a fishbone diagram was carried out to find out the factors causing the WLC Autelan equipment to experience a decrease in performance quality assisted by FGD activities. It was found that there were 4 main factors, namely measurement, milieu, method, machine. Furthermore, the proposed improvement is carried out using the 5W1H method. Some suggestions for improvement include making a monitoring dashboard for all managed devices, changing the WLC devices system to active-backup, carrying out preventive maintenance activities twice a year, and moving devices from a room with a stable room temperature so that the device does not overheat.
