<![CDATA[Implementation of mobile rack warehouse is commonly used in manufacturing industry because it can minimize the warehouse area used. Applying picking orders in taking of Stock Keeping Unit (SKU) on mobile rack warehouses could give fast loading order. This research aims to find out which algorithm is better in applying picking order sequence in mobile rack warehouse. The algorithm used is Simualted Annealing (SA) and Harmony Search (HS) algorithm. Both of these algorithms will be compared in terms of the gap with the shortest path method.The result shows that the HS algorithm produces a better solution than the SA algorithm with lower CPU time, but the convergence rate of HS is lower than that of SA.HS was able to produce a better solution than the shortest path method of 9 cases, while SA only 8 cases from 15 cases.]]>

<![CDATA[The effectivity improvement of production facility in factory is not only on facility manitenance but also on human resources. Total Productive Maintenance (TPM) gives an optimal solution to effectivity improvement. A case study of TPM implementation have done in non sewing department of PT Kerta Rajasa Raya. Abstract in Bahasa Indonesia : Peningkatan efektivitas dari fasilitas produksi di suatu perusahaan bukan hanya terbatas pada perawatan fasilitas kerja saja tetapi juga sumber daya manusia. Total Productive Maintenance (TPM) memberikan suatu solusi optimal terhadap peningkatan efektivitas dengan melibatkan semua sumber daya manusia yang bertanggung jawab terhadap fasilitas produksi. Suatu studi kasus terhadap pengimplementasian TPM dilakukan di departemen non jahit PT. Kerta Rajasa Raya. Kata kunci : TPM, MTTF, Autonomous Maintenance.]]>

<![CDATA[Shewhart's dan S(or R) control charts have been used very widely in industries . For several decades, many researchers have endeavoured to develop new algorithms to raise the detecting effectiveness of the control charts. While these methods do increase detecting effectiveness, they usually increase the type I error at the same time. This error give the warning that process is unstable. In this article, we design a single control chart to subtitute -S control chart that have the same sensitivity but doesn't increase error type I. We analyze those factors and their influence to a single and -S control chart. The ARL1 value in -S control chart i s compared with a single control chart . The result shows that a single control chart effective enough. Abstract in Bahasa Indonesia : Sampai saat ini Peta Kendali dan S (atau R) merupakan peta kendali yang umum dipakai di kalangan industri. Pada beberapa dekade, sejumlah penelitian dilakukan untuk menemukan algoritma yang dapat meningkatkan kepekaan peta kendali dalam pendeteksian. Pada saat kepekaan peta kendali tersebut meningkat maka bersamaan dengan itu kesalahan dalam pendeteksian juga meningkat. Di dalam artikel ini penulis mencoba membangun sebuah peta kendali tunggal yang dapat menggantikan peta kendali -S yang memiliki kepekaan sama tetapi tidak meningkatkan kesalahan jenis I. Untuk itu dilakukan simulasi yang menganalisa faktor-faktor tersebut dan pengaruhnya terhadap peta kendali -S dan tunggal. Nilai ARL1 peta kendali -S dibandingkan dengan nilai ARL1 peta kendali tunggal. Hasil simulasi menunujukkan bahwa peta kendali tunggal cukup efektif. Kata kunci : ARL0, ARL1, a1]]>

<![CDATA[PT. X is one of company that concerns with continuous improvement. PT. X attempts to apply the concept of lean manufacturing in order to identify waste. Value stream mapping is one of the tools from lean manufacturing that can illustrate the entire process and identify waste ranging from the arrival of raw materials to the delivery of finished goods. Value stream mapping will be carried out at PT. X for department A. Through the current state value stream mapping can be seen that there are some waste in PT. X for department A ranging from the arrival of raw materials to become finished goods, among others is waste motion, over-processing waste, defect waste, inventory waste, and waste waiting. Design of future state value stream mapping is based on the proposed improvement given to the company. Future state value stream mapping can reduce lead time 41% from the current state value stream mapping.]]>

<![CDATA[Problem were found in a uniform warehouse in PT. XYZ are about uniform storage and overstock. This thesis give proposal to decrease uniform inventory cost and rearrange uniform warehouse. Propose for improvement which is given are uniform warehouse guideline with Kaizen concept, determine maximum inventory with Periodic Review, and guideline of uniform database. With Periodic Reviewâs method, the company can decrease percentage of stockout. Percentage of stockout is 3%.]]>

<![CDATA[The percentage of unaccountable in the Secondary Processing Department during 2013 (early 2014) is 0.66%. There are three factors that affect that percentage. Those are processed tobacco spillage, tobacco stem, and another factor that has not been identified. The reduction of processed tobacco spillage and tobacco stem will reduce the percentage of unaccountable. Improvements that implemented are providing tools and modify some machines at Feeding to SKM Area, changing Stem Boxâs setting, replacing broken parts from Stem Box, and providing sieving tools. Other improvement is implementing work instruction to prevent the clean processed tobacco spillage become waste. Improvements that implemented had reduced the percentage of unaccountable and had increased the Yield Secondary Processing by 0.13%.]]>

<![CDATA[PT. X measures internal customer satisfaction using an index called Internal Supplier Service Rate (ISSR) monthly. One of the order intake in PT. X is material that called as material shipment. Currently, Order intake for material shipment was increasing, but the increasing not in line with the ISSR. PT. X only achieved ISSR as 89,5% in 2013 which target is 95%. This final assignment attempts to increase ISSR in material shipment activity. The proposed improvements are standar work flow, material forecast for Supplier, coordination between company and Supplier, and an additional staff for material shipment. The proposed improvements are implemented and the ISSR increases to 97,5%.]]>

<![CDATA[PT. XYZ is a company which is engaged in the field of frozen shrimp exporters that produce shrimp sushi, shrimp tempura, and shrimp peeled. The problem that occurs is often failure to achieve the production target in the process of shrimp sorting. The factors that cause the failure of production targetâs achieving are production target which is too high and the workers who are slow in the process of sorting. Based on these problems, in this research is undertaken the improvement of production target and the improvement of the movements of the left hand and right hand of workers in doing the sorting. The research concludes that the production target need to be lowered and is undertaken the improvement of the left hand and right hand of workers so that the production target will be achieved and the efficiency reaches 8,81%.]]>
