ABSTRACT

ABSTRACT-The purpose of this study is to (1.To analyze the remaining work itemsat month of 14th from the project starts, 2). To analyze the remaining cost items at month of14th after the project start. And the last is 3). To reschedule and to optimize the time and costby use Critical Path Method (CPM).

This study will analyze time and cost controlling by using CPM approach on theproject. Based on the background of the study, the statements of the problems can beformulated as follows: (1) How is rescheduling in optimization of time on Palur Fly over ofSurakarta by using Critical Path Method (CPM)? and (2) How is the implement of the normaland the crash of the cost on Palur flyover in Surakarta by using Critical Path Method (CPM)?.The writer analyzed the fly-over project implementation fly over Palur in Surakarta whetheraccording to the time plan. By rescheduling the plan and make optimization of time andminimizing cost with CPM (Critical Path Method).

Based on the result and discussion, the conclusion of this research as follows: Theimplementation of the project is not in accordance with the plan, it is too late because of theweather and can be solved by increasing the valve of workers. Based on the reschedulingalternatives can be implemented as the alternative I with 160 days shorter and the rest of costRp 32.556.381.150

Keywords: Critical Path Method (CPM), Project Management, Time Control, and Costcontrol.
