Abstract

This study aims to optimize the time required to obtain information in the operational monitoring process of the Utility Department at PT. X, a cigarette production company that has been operating in Surabaya, Indonesia since 1962. Time is a crucial factor that needs to be considered by all industry players, including PT. X. Therefore, PT. X has initiated the implementation of the Industry 4.0 concept to improve time optimization, although it is not yet fully implemented. It is evident that there are still operators who manually input data, and the duration of data collection and processing hampers the optimization by implementing solutions based on identified root causes. After the implementation, there was a significant decrease in the time required for data collection to become information for the Boiler by 96%, Compressor by 96%,and PDAM Water Supply by 97%. Thus, it can be concluded that the implementation of the improvement project is aligned with the company’s objective of achieving time optimization in obtaining information during the operational monitoring process at the Utility Department of PT.

PT.X experiences a large non-value added. This causes waste so that waste needs to be handled. to deal with waste effectively, the biggest waste must be found first and dealt with. To handle the waste problem, a proposal is made using the DMAIC, VSM, 7 Waste, Stopwatch Time Study, 5 Why, and 5S methods. After identification, it was found that there was waste in the trimming section. In the trimming section, there is a waste inventory that correlates with waste waiting, namely taking glass that takes a long time. This is due to the absence of a glass storage system. After making a proposal using the 5S method, the results are obtained in the form of a glass storage arrangement, a glass sorting system, a glass storage cleaning schedule, a glass storage Standard Operating Procedure (SOP), and a glass storage Checklist. This system is made so that later it is hoped that 5S can become a habit.

Abstract

Construction projects run the risk of not conforming to the initial expectations of development. It is very difficult to estimate the time of a project because a project is not repetitive, there are different challenges in each development project. Delay in completing a project will cause waste in the form of overtime and overbudget. This research was conducted using judgment sampling to 5 respondents who were expert contractors. The objectives to be achieved through this research are to identify the dominant factors causing delays in a residental project using the Decision Making Trial and Evaluation Laboratory (DEMATEL) method and modeling the relationship between the factors that cause delays in residential construction projects using the Interpretive Structural Modeling (ISM) method. The result of this research is the existence of 8 levels of sub-factor hierarchical structure which becomes the framework for contractors and project owners to reduce the risk of delays in residential construction projects. The dominant causes of delays in project development are design changes during construction, late delivery of materials, late approval of work drawings, late payments, and inappropriate work methods.
