Abstract

Production process at PT. Showa Indonesia Manufacturing is not always smooth, due to the ignorance of the reliability of the machine. Breakdown can occur at any time and cause uncertainty of the availability of machinery in the production process, causing considerable losses to the company. This study was conducted on a compressor machine used to produce the pressurized air that used to run the production machinery. Based on the research, the highest damage level is on the compressor machine 4, 8, 10, 5, 16, and 6 with total damage of 70.1%. This is due to the complex machine system and the less optimal maintenance system. Reliability Centered Maintenance (RCM) method is used to analyze the system to identify components that fall within the critical category. The results of the analysis, obtained some critical components which required optimal replacement interval by minimizing downtime. Further planning activities on each critical component is based on FMEA and RCM Decision Worksheet. With the application of RCM method, total downtime decreased by 44.59% from previous preventive actions.

Abstract

Line balancing is a jobs assignment into a number of work stations that are interrelated in a track or a production line with an objective to minimizing the idle time on the line that is determined by the slowest operation. In line welding 1DY models includes eight work stations where one work station is done by one operator. Problems have been found that these operators have very long idle time and also there is too much wip that creates bottleneck in the production line so these leads to a waste of manpower and time. This waste of manpower and time need to be reduced by determining the optimal amount of labor in order to avoid excessive idle time but work can be done effectively and efficiently. One way to adress imbalance line is to apply line balancing methods.The results of this research shows that the line balancing methods can reduced the waste of time and give solutions for the optimal amount of labor requirements for line welding 1DY models.Keywords: Line Balancing, Workstation, Production Line, Idle Time, Bottleneck.

Abstract

PT XYZ is a company that produce tools, machine parts, and special purpose machines. Based on data from the production department, there are some products with high defect and then need rework. This condition would be very harmful because it will increase the cost that should not be necessary. The research is to find the cause of the occurrence of this defect and then fix it. From the observation result showed that the production of feed roll component has a high defect rate which is 70.59% must be reworked, based on the data during January - September 2016. In October - December 2016 the improvement effort was done by using lean manufacturing approach and PDCA. The results of this improvement provide improved quality of the feed roll component so that the rework gradually decreases and eventually does not exist. Then the cost of production before the repair of Rp 668,694, - reduced to Rp 413,983, -. There was a significant decrease in production cost by 38%.

Abstract

This research concerns about the design and implementation of a new information system which will simplify the processes of the current system and its impact on the warehouse staffs. In order to automate the processes, a programmed information system is designed using Microsoft excel VBA, a basic programming function inside Microsoft excel. First, the current system is analyzed. Next, the user requirements and proposed system requirements are analyzed to make the system design. Then, the program is developed and tested by using VBA (Visual Basic for Applications). Then, the new system is implemented and the implementation results are analyzed. The results found that the new system successfully fulfilled the objectives of this research and the user requirements, although there are still some improvements which need to be done. During two months’ period of implementation, there are some problems encountered which required the programmer to improve the system. Like every system, there are some advantages and disadvantages found in this new system.AbstrakPenelitian ini fokus kepada  desain dan implementasi sistem informasi baru yang akan mengotomatisasi proses dari sistem saat ini dan dampaknya  terhadap staf gudang. Dalam rangka untuk mengotomatisasi proses, sistem informasi yang terprogram dirancang menggunakan Microsoft excel VBA,sebuah  fungsi dasar pemrograman dalam Microsoft excel. Pertama, sistem yang sekarang dianalisis. Selanjutnya, kebutuhan pengguna dan kebutuhan sistem yang diusulkan dianalisis untuk membuat desain sistem. Kemudian, program ini dikembangkan dan diuji dengan menggunakan VBA (Visual Basic for Applications). Kemudian, sistem baru diimplementasikan dan hasil dari implementasi dianalisis. Hasil penelitian menemukan bahwa sistem baru berhasil memenuhi tujuan penelitian ini dan kebutuhan pengguna, meskipun masih ada beberapa perbaikan yang perlu dilakukan. Selama periode dua bulan implementasi, ada beberapa masalah yang dihadapi yang membutuhkan programmer untuk mengembangkan sistemnya. Seperti setiap sistem, ada beberapa kelebihan dan kekurangan yang ditemukan dalam sistem baru ini.

Abstract

A manufacturing company and heavy equipment attachment service provider experiencing problems in increasing production. One of its flagship products, Tipper Vessel (TV) 24m3, has constraints in terms of fulfillment of component requirements by suppliers. the company needs to add new suppliers and divide component purchases to several suppliers using more effective methods. This research uses Analytic Network Process (ANP) is effective and efficient in supplier determination. Determination of supplier company has four criteria that are rejected rate, payment transaction, delivery, and price. Data processing in the process of distributing the suppliers using questionnaires with paired comparisons and historical data about the performance of the three suppliers to be used by the company. Assisted by using Super Decisions Plus 1.6.0 software for ANP calculation, an appropriate supplier recommendation is made for certain components.

Abstract

PT. X has two procedures to control and monitor every work that is carried out inside the company area. One of them is Work Permit or known as Permit to Work (PTW). As identified during its direct observation in a quantitative approach by flow process chart and document flow chart, there are several problems in the system. The existing system has also been identified as running ineffectively. Management of PT X approved application development for the system as the problem solution. By following the guidance of SDLC phases, two customized applications were developed using visual basic for application. At last, a further observation was carried out following their implementation to the system. The final result of this research shows that the applications are successfully improving the system.

Abstract

Line x cc merupakan lini produksi dari machining departement yang finished product-nya akan dikirim ke engine assembly line (user) untuk kemudian dirakit menjadi unit mesin sepeda bermotor. Permasalahan yang terjadi adalah adanya perbedaan cycle time keduanya sehingga banyak terdapat stok finished product pada line x cc. Untuk mencari penyebab permasalahan tingginya waktu operasional pada line x cc, dilakukan pengukuran waktu elemen kerja dengan cara mengukur time study. Dari hasil yang didapat, dilakukan analisis line balancing untuk mengetahui penyebab ketidakseimbangan lintasan pada line x cc. Perubahan process flow dan elemen kerja dapat memperbaiki keseimbangan lintasan kerja serta menurunkan average cycle time produksi sebesar 17,28%, yaitu menjadi 75,79 detik. Selain itu, pitch time dapat diturunkan menjadi 82,44 detik, selisih 9,19 detik dari cycle time. Efisiensi lintasan (EI) naik menjadi 91,94%; smoothness index (SI) turun menjadi 6,65; balance delay (BD) menjadi 8,06%; dan gap cycle time turun sebesar 42,20% menjadi 27,79 detik.
