Abstract

The purposes of this thesis are designing a planned maintenance and man power planning in the maintenance department of PT X Previously, the PT X used breakdown and cor­rec­tive maintenance. The maintenance procedures will be revised into corrective main­tenance and when continuous pro­duction system is executed, corrective & preventive maintenance will be applied. For defining those procedures, first we identified the machines’ failure and redesign­ed the production system. Additionally, we propose four level of man power planning based on their skill and company management want it divide into four level.

Abstract

Human resources (HR) department is a department in charge of hiring, training, assess, and provide compensation to employees, pay attention to their labor relations, health and safety, and justice isses. Meeting the employees’ needs, the HR department must have a clear workflow. Therefore the Standard Operating Procedure (SOP) is a necessity to be updated, so that there will be no social gap between the parties. In this work, we updated eight SOPs that have no longer accordance with the aggrement of HR department and its vendors which includes several processes in the HR medical of vendor by vendor N and vendor BL. The SOP for hospital regristration processes was created for Hospital Handover Project such that each group (the east and the west group) can handle those processes individually.

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

PT Charoen Pokphand Indonesia Balaraja is a company in feed production. One of the ways for PT Charoen Pokphand Indonesia maintaining their feed quality is through documentation of all activity that related with production in procedure. The last update of procedures was in 2008, so some procedures are no longer applicable in company’s current condition. So that, the procedures must be updated and those procedures can be used as work guidance and work standard. Total of 8 procedures, 34 work instructions, 14 forms, 10 appendixes in Production Department and 13 procedures, 109 work instructions, 31 forms, 7 appendixes in QSHE Department, which had been revised.

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

In this thesis we modeled the sales pipeline using auto regressive moving average, ARIMA(p,d,q) under R-Software. Those selected models are used to forecast the standard water pipe and black, standard water pipe and medium standard black pipe, SCH 40 standard water pipe and black, BDA standard water pipe, standard water pipe, medium B, coil, and furniture pipe future demands.

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

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.

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

It is generally easier to predict defaults accurately if a large data set (including defaults) is available for estimating the prediction model. This puts not only small banks, which tend to have smaller data sets, at disadvantage. It can also pose a problem for large banks that began to collect their own historical data only recently, or banks that recently introduced a new rating system. We used a Bayesian methodology that enables banks with small data sets to improve their default probability. Another advantage of the Bayesian method is that it provides a natural way for dealing with structural differences between a bank’s internal data and additional, external data. In practice, the true scoring function may differ across the data sets, the small internal data set may contain information that is missing in the larger external data set, or the variables in the two data sets are not exactly the same but related. Bayesian method can handle such kind of problem.
