“…The oversize test is used in quantitative analysis to determine the deviation of the size of the nata de coco pieces produced against the predetermined cut size criteria (Basuki & Fahadha, 2020). The sample of nata de coco observed was nata from 0.3 cm in size which was taken as much as 100g and came from conventional cutting machines, conveyor machines, and chain conveyor machines.…”

The nata de coco cutting process takes place using three types of cutting machines, namely conventional cutting machines, conveyor cutting machines, and chain conveyor machines. The process of cutting nata often experiences practical problems, especially on the size of the pieces that do not match the predetermined criteria. This results in a decline in product quality and customer acceptance. The purpose of this study was to determine the causes of problems in the process of cutting nata de coco type NDC 12. Problem analysis was carried out using quantitative methods presented in the table of oversize nata de coco test data on each machine used so that deviations in the size of the nata produced against the criteria had been determined. determined, as well as qualitative methods with fishbone diagrams based on data from observations, interviews and documentation. The results of the size of the NDC 12 nata de coco pieces in general are still not in accordance with the standards set by the company, it can be seen from the average value of the largest defect in the chain conveyor machine, which is 12.75g pre-sorting treatment and 7.17g post-treatment. sort. This is largely due to machine work that is less than optimal and the pre-cutting process is not in accordance with work procedures.

“…Metode yang digunakan dalam menganalisis penyebab kehilangan minyak (oil losses) yaitu fishbone diagram, dimana fishbone diagram telah diperkenal oleh Dr. Kaoru Ishikawa dari Jepang, sehingga metode fishbone diagram juga disebut dengan Ishikawa diagram sesuai dengan nama yang telah memperkenalkan fishbone diagram [13][14][15]. Fishbone diagram cukup sederhana namun sangat efektif dalam menganalisis dan mengidentifikasi penyebab sebuah hal yang belum terurai.…”

PT. Y is a company engaged in the processing of fresh palm fruit bunches into Crude Palm Oil (CPO), and has a production capacity of 30 tonnes/hour. The CPO production system generally goes through a long process and there are several processes that are not optimal. One of the processes is pressing, where this process experiences a lot of oil loss. Oil loss experienced at PT. Y of 6.28 to 6.32 percent of total production. Therefore, it is important to identify the causes of oil loss in the pressing process so that it becomes a preventive measure and can reduce the percentage of oil loss during the production process. The purpose of this research is to identify the factors that cause CPO oil loss and to recommend solutions to minimize CPO oil loss in screw press machines using fishbone diagrams. A fishbone diagram is used to identify the root causes of problems in a process. The cause of the problem is often caused by five elements, namely Man, Method, Machine, Material, and Environment. Fishbone diagram is useful for finding the factors that cause a problem. The results obtained from the fishbone diagram are several factors that cause oil loss in the pressing process or in the screw press machine including machine factors, raw materials, humans, and method factors. Recommendations that can be implemented by companies include routine maintenance of screw press machines, both corrective maintenance and preventive maintenance, it is necessary to control the quality of fresh fruit bunches from the beginning of harvest until the fruit reaches the loading ramp station, and this requires training so that operators can better understand how to machine operation.

Fuel is one of the tools to drive the machining system that moves from the fuel tank to the engine. Although there are several areas that have switched to using electric vehicles, vehicles that use fuel oil still dominate the public in various countries. The purpose of this research is to identify the causes of a dirty fuel filter in an auto repair shop. The methods used in this analysis are Failure Mode and Effect Analysis (FMEA) and fishbone diagram analysis. Based on the results and discussion, the cause of the dirty fuel filter is the causal factor from the method side, namely due to negligence in maintenance, from the material side because the fuel tank is dirty and the fuel is not good, from the engine side because of continuous use without maintenance, from the human side because it is not routine maintenance, due to carelessness in maintenance, and due to frequent changes in the type of fuel.
