Abstract

Project management is a process of activities to manage organizational resources owned by the company to achieve certain goals. The Terbangi Besar-Kayu Agung Lampung toll road construction project is a project that must be completed in a short time. This study has a purpose to evaluate the performance of the construction project of the Terbangi Besar-Kayu Agung Lampung toll road using the PERT and CPM methods with a toll road length of 189.2 km (117.6 miles). Based on the results obtained by using these two methods, the project completion time which was originally 238 days can be completed in just 119. There are several alternative proposals. The alternative proposal by adding work shifts that have crashed 32 times has an optimal cost of IDR 39,154,229,627.03 and an optimal time of 119 days. While the alternative of increasing the capacity of the equipment produces an optimal time of 189 days and an optimal cost of IDR 39,205,747,076.44 with the crashing process reaching 12 times of crashing. The Toll Road Development Project Planning is scheduled to have a normal time to work for 238 days at a total cost of IDR 39,349,097,164.38.

Abstract

The current competition in the food industry encourage companies to be able to produce products that are diverse, in a good quality, and in a timely manner to meet the company's production targets. PT XYZ is a food company in Indonesia. To be able to meet production targets, companies must adjust their production capacity by utilizing their workforce. However, the problem is that there are so many variables involved in the system so that the problem becomes more complex and hard to solve. Therefore in this study, a dynamic system approach is used to be able to see the interactions between variables in the system using Vensim software. Based on the research that has been done, the values ??of E1 < 6% and E2 < 2.5% indicated that the data used in this research is valid in other words the model used has represented the real system conditions. From the research, the best result is to gradually increase the installed capacity so that there is no over production occured. Using this scenario, the availability of raw materials for is 5901 boxes.
