“…The primary purpose of this method is to identify factors that are represented in the form of type, size, location, and time as a result of certain habits, behaviours, and conditions that need to be changed to avoid unnecessary errors. Accurate and systematic results can be obtained by identifying the root causes of residues using the root cause method (Wibowo et al, 2018). The RCA process consists of five separate steps: defining problems, collecting data, analyzing data, identifying root causes, and identifying corrective actions (Groot, 2021).…”

This study aims to analyze the causes of delays in decision-making within the company. Managers can identify several constraints in decision-making by using analytical tools. In this study, the device used to analyze the problem is root cause analysis. Root cause analysis is used to determine the initial cause of the issues. The method used in the root cause analysis is a fishbone diagram where the fishbone diagram can identify some of the problems that underlie the constraints in decision making. This study uses a qualitative descriptive method by taking data from interviews and documentation. The results of this study can be seen in decision making four problems underlie the inhibition of decision making. The problem is the first decision-maker; namely, the company's management is not wholly a determinant in making decisions. The second problem is that the information presented as a guide for decision-making is inaccurate, not timely, and irrelevant. The third problem is the absence of software that processes data into information needed by company management. The last problem is the lack of integration between divisions, so the resulting information is out of sync. Root cause analysis and fishbone diagrams, that was possible to analyze in detail the causes of delays in decision making. In the end, management can find solutions to each of these problems. Management will search each problem for the root cause, and the answer that they will give will be right on target so that the hope to minimize the obstacles to decision making will be implemented.

“…One way to find out the root cause of a problem is to conduct an interview using the 5 Whys, namely the repetition of up to five times the question why (why) to understand the root cause of a problem [14]. Identifying the main factors causing Boiler start-up failure using the Root Cause Analysis method can obtain precise and systematic results [15].…”

PT. PLN (Persero) UPK Nagan Raya is a Steam Power Plant (PLTU) that uses coal as Boiler fuel to produce thermal energy. one of the initial stages of the Boiler is Startup as the basis for the start of Boiler operations. The purpose of this study is to analyze and avoid the risks that can make the operating system not run. Based on the research conducted, there are 8 risks that can cause failure. Based on the Grey FMEA method, the priority risk that occurs is that the FO fast shut-off cannot be O / C CCR with a value of 0.491 and also in the flexible joint line of the lower burner air there is a leak of 0.503. The result of the Root Cause Analysis method, the cause of the FO fast shut-off cannot be O / C CCR is the limited facilities and infrastructure for device maintenance which causes obstacles for workers so that the results worked on are not effective and efficient. Meanwhile, the risk that the flexible joint line air lower burner has a leak because it is not critical equipment only used at certain times so the check is neglected which makes the flexible joint leak. The solution that can be done is that as much as possible the operator must carry out routine maintenance/overhaul on the flexible joint so that there is no failure that can hinder the operation.

“…There are two types of costs used in this research, namely fixed costs or setup costs incurred when a pattern j is cut and variable costs or material costs incurred for each unit of iron stock used, which comes from the cost of purchasing iron. For example, the setup fee is Rp3.000.000,00 and the weight of iron is 256 kg at a price of Rp11.000,00 per kilogram, so the cost of buying iron is Rp2.816.000,00 [17].…”

Cutting stock problem (CSP) is a problem of cutting an object into several smaller objects to fulfill the existing demand with a minimum unused object remaining. Besides minimizing the remaining of the object, sometimes there is another additional problem in CSP, namely minimizing the number of different cutting patterns. This happens because there is a setup cost for each pattern. This study shows a way to obtain a minimum number of different patterns in the cutting stock problem (CSP). An example problem is modeled in linear programming and then solved by a column generation algorithm using the Lingo 18.0 software.
