Abstract

Reliability centered maintenance adalah suatu metode yang digunakan untuk menen­tukan apa yang harus dilakukan supaya aset fisik yang di­miliki dapat tetap terus diguna­kan. Peng­olahan metode reliability centered maintenance membutuhkan jawaban responden se­ba­gai sum­ber utama. Jawaban responden yang tidak selalu dapat mutlak ‘ya’ dan ‘tidak’ me­nyebabkan adanya ketidak pastian. Metode fuzzy akan menghilangkan ketidakpastian dengan mem­­­berikan kebenaran secara gradasi sehingga jawaban responden dapat digunakan didalam me­­tode reliability centered maintenance. Data dan jawaban dari bagian pemeliharaan mengenai komponen mesin yang meng­alami ke­gagalan akan diproses menggunakan kedua metode (reliability centered maintenance dan fuzzy lo­gic) sehingga dapat ditentukan jenis pemeliharaan. Hasil jenis pe­meliharaan metode RCM meng­gunakan pendekatan fuzzy logic lebih efektif dan tepat da­lam mendeteksi jenis pe­meliha­ra­an bagi mesin perusahaan.

Abstract

UD. X is a crackers factory that currently has a production capacity of 3.6 tons for a day. UD. X wants to increase their production capacity to fullfil their customer’s needs. Production capacity can be increased by improving their steam and packaging process. The drying process is improved by changing the schedule to maximize their production capacity. The packaging process uses time study, therbligs, and right- and left- hand chart to improve the process itself. The drying process is improved by building inventory room for their work in process. The packaging process is improved by introducing two tools which are packaging ring and digital weight scale.The suggestion for steam process increase the production capacity from 3.6 tons to 7.2 tons and the recommendation for packaging process also increase their production capacity from 7.11 ton to 13.36 ton.The suggestion for steam process has been started so the capacity of steam process was increased by 100%. The improvement of packaging process is being applied by adding the operator from 14 to 16 which result higher capacity from 7.11 ton to 8.136 ton

Abstract

PT. X is a manufacturing company that produce rigid packaging for cosmetic products. Between January 2018 - March 2019 PT. X got a delivery delay problem up to 391 times, therefore a research was conducted to identify the causes of the delay. This research used root cause analysis as an approach for analyzing the cause of the delay. Delivery delays that had happened in PT. X were caused by actual process lead time (58 days) that took longer than planned process lead time (52 days), therefore creating a gap (6 days). The root cause of the delivery delays are production problems that can be categorized into four type, which is Downtime (39.5%) that caused by mold, machine, process, color, robot, and set up problems; Loss Hour (26.3%) that caused by no norder and preventive maintenance problems; Speed Gap (24.2%) that caused by machine’s actual cavity that are less than the planned cavity and machine’s actual cycle time that took longer than the planned cycle time; Time Reject (10.0%) that caused by black spot, material spot, amandel, appearance, gripis, baret, and mulut tidak pres problems. The potential decrease of the actual lead time when all of the root causes are dealt with are 29.5 days (65.90%)

For instance, there are 1000 sheets produced from the beginning of process, but in the next, there are only 800 sheets left. Through observations and interviews, it is found that the problem occurs due to the number of production output is not clearly recorded and the absence of head of department verification. Some suggestions are given, such as making tags at the end of the process at Raw Material Warehouse, positioning reject goods at predetermined place at Offset and Plong Department, and counting the number of rejects in both department. Besides that, acceptance sampling is implemented at Lamination and Glueing Department. In addition, it is also suggested the right method to measure paper in the pallet using measurement tools; the right standard of paper gramatur and work instructions about production order (PO) fulfillment at all departments.
