Abstract

Project management is an effort to control projects by paying attention to time and resource availability. This control is necessary to achieve targets as planned. The aim of this research is to evaluate work time and project costs using the CPM method for the cyclone making project at PT Putra Dharma Kencana in Mojokerto district. This research uses quantitative approach techniques which are analyzed using CPM and Gantt Chart using POM QM software. In this project there are 10 activities in the order, namely A-B-C-D-E-F-G-H-I-J, the project was planned to be completed in 84 days, but was completed in 98 days. The results of the CPM analysis show 2 activity paths with the critical path, namely A-E-F-G-H-I-J with a time of 62 days. The results of the Gantt Chart analysis of activities that can be done simultaneously are activities B and E on the 7th day, activities C and E on the 14th day, and activities D and F on the 21st day. By implementing the CPM method, costs can be reduced from IDR 48,720,000 to IDR 23,560,000.

Abstract

UD H and M Electric is a manufacturing company engaged in the production of medium voltage overhead line (SUTM) components, one of its products is the Connection Clamp. The purpose of this study is to determine the level of waste that occurs and provide suggestions for improvements to reduce waste. The research data used is questionnaire data with respondents who meet the qualifications and know the entire flow of the Connection Clamp production process, as well as waste data that occurs during the production process. To determine the level of waste that occurs and provide suggestions for improvements, the Waste Assessment Model, Process Activity Mapping, Fishone Diagram, and Failure Mode and Effect Analysis methods are used. In the Waste Assessment Model method, the top three critical levels of waste were obtained, namely waste defect of 19.55%, waste motion of 16.88%, waste transportation of 16.10%. In the Failure Mode and Effect Analysis, the Risk Priority Number (RPN) value was obtained from the top three wastes with each sub-waste, namely waste motion sub-waste lifting products manually with a score of 280, waste motion sub-waste rearranging before the process with a score of 240, waste transport, namely the distance of the work station is less than optimal with a score of 200, waste reject sub-waste cracked plates with a score of 168, waste Defect, namely imperfect layers with a score of 168.
