Abstract

This paper aims to analyze the cycle time of the assembly line of one of the weapons products at PT. Pindad (Persero) and to explore the effective methods to improve its performance. The method used is a quantitative analysis of assembly data involving 155 components and 56 tasks distributed over 43 work stations, accompanied by document analysis, especially on scientific literature, to elaborate various appropriate methods to become solutions to the problems encountered. The results show that almost all workstations had a cycle time greater than the takt time. It is also known that there is an imbalance of existing workstations, with the lightest workload lasting 67 seconds while the largest workload lasting 253 seconds. The results of the elaboration of the literature show that several potential methods can provide solutions to the problems encountered by considering the characteristics of the assembly line with a straight-line configuration. This study contributes to the literature by analyzing cycle times and assembly line balances in the defense industry relatively rarely studied in Indonesia.

Abstract

Reliability of electricity supply is urgently needed by modern industry because disruptions can directly impact production levels, costs and company profitability. The purpose of this study is to determine the characteristics of the existing maintenance of electric power distribution to industrial customers of PT PLN (Persero) UP3 Karawang and to propose appropriate maintenance methods to improve its performance. The method used is a case study with data collected through observation, interviews, and analysis of relevant documents. The results of the study indicate that the trend of feeder disturbances during 2017-2020 has not met expectations, the realization of the average interruption frequency index (SAIFI) system continues to increase in succession 3.12; 3.85; 5.47; and 6.92 times/customer, as well as the realization of the system average interruption duration index (SAIDI) with an increasing trend, respectively, 182.97; 314.31; 1015.55; and 612 minutes/customer. The three highest causes of disturbances were jointing (39%), followed by third party causes (36%) and cubicle damage (15%). The author proposes the TRDX method to improve the reliability of electric power supply to industrial customers.
