Comparison of Activity Implementation Plan Time with The Conventional And The Pert Method

Abstract

The implementation of the Road and Bridge Preservation Project in several districts in Bali, namely Gianyar, Bangli, Klungkung, and Karangasaem, experienced a setback in the 18th week by 4%. In the implementation, a design change caused a volume change and caused delays. The purpose of this study was to compare the implementation plan with the conventional method and the PERT method with Microsoft Project. This method is often used in project planning using a network that requires three time estimates: the most likely, optimistic, and pessimistic. The data used were the Budget Plan data, the Time Schedule (planning time), the work calendar, and the interview results related to the percentage of success of activity time from the contractor. The data were analyzed with Microsoft Excel to obtain the optimistic, pessimistic, and most likely times. Based on the PERT analysis, data processing was then continued with Microsoft Project to produce the optimal time. The planning time obtained using the conventional method is 226 days, and using the PERT method, the optimistic planning time is 215 working days, the pessimistic planning time is 246.5 working days. The optimal planning time is 227.58 working days. The implementation time of the PERT method analysis is 1.58 days longer than that of the conventional method
