Abstract

PT. X is one of the cigarette manufacturing leaders in Indonesia. Products from PT. X is distributed inside and outside Indonesia through a number of markets. Therefore, a good Allocation Planning is a must. PT. X wants to map the activities in the Allocation Planning and Value Stream Mapping (VSM) is chosen for accomplishing that task. First, we map the current situation using VSM, we found two wastes occurred during the Allocation Planning, which are waiting time and motion. After that, various improvements are executed to reduce those wastes, and then once more the VSM are applied. The results showed that in overall the lead time decrease over 34.88%.

Abstract

The breakdown machines in the production process at PT. X especially in the Material Mixture Division are occurred quite often. During January to February 2015, those machines 23 times (22.5%) are breakdowns. Therefore, the objective of this research is to design the right maintenance strategy in particularly for machines which have longest downtime. Reliability Centered Maintenance (RCM) with Dempster-Shafer approach is used to solve this problem, since the company does not have historical data. As the results, replacement and condition based maintenance are chosen. Those strategies are the most appropraite and possible ones strategies to be applied in PT. X.

Abstract

In 2013 PT. X experienced downtime frequently. Some of the failures that lead to the downtime are broken shaft helical gear, broken fan funnel axle, broken long axle; broken worm, worn down drig laker, and worn down blade. The maintenance strategy in the company has not covered all failures specifically. Thus, this project is Reliability Centered Maintenance Method (RCM) with Dempster-Shafer approach which covers those failures. It was found that condition based maintenance is the best strategy for maintaining each failure. This strategy is easily to apply since the company has implemented autonomous and planned maintenance.

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

The library attendance at Petra Christian University is decreasing. We are interested in finding the factors affecting that attendance. In this study, we applied the LIBQUAL one of library quality measurements, and added some external and internal factors to answer the quest. Additionally, we also used the Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) as tools for analyzing the constructs. As the result we found out that the factor that affecting library attendance is library as place, and the factor that doesn’t affect library attendace is teacher motivation.
