WORKLOAD ANALYSIS OF SURABAYA CITY PUBLIC STREET LIGHTING MAINTENANCE FIELD OFFICERS

Surabaya City has more than 93,000 PJU (penerangan jalan umum/public street lighting) points spread throughout the city, and this number will continue to grow in the future. The number of PJU points certainly requires a good management system, one of which is in terms of maintenance. However, in terms of maintenance, 8 field officers in each of the seven existing rayons are deemed unable to do their job optimally because several things, such as the achievement of the KPI 1 x 24 hours after the report comes in, are often not achieved, the irregular holiday schedule of field officers, and obstacles in the field that hamper fieldwork. Therefore, a workload analysis is carried out using the Stopwatch Time Study (STS) method which is continued until obtaining Full Time Equivalent (FTE) number, and the NASA Task Load Index (NASA-TLX) method, as a reference for calculating workload and human resource requirements. The workload analysis was carried out by conducting field observations to seven existing rayons, distributing questionnaires to 57 field officers related to mental workload based on the NASA-TLX method, and conducting interviews and discussions with rayon heads to determine the performance rating, the level of influence of field obstacles on field work time, and the validation of field observations. The results indicate that all PJU rayons in Surabaya City require additional field officers to handle the average work each month. Then, regarding mental workload, the overall average mental workload of the field officers was 88.58, which is classified as "very high". Several recommendations have been written to improve the work system in the PJU Unit in Surabaya City as well as to support recommendations for reallocating PJU field officers in Surabaya City.
