Abstract

Based on ultimate goal of each company in gaining maximum profit with minimum total cost then one of alternative should be done in achieving this goal is avoiding excessive raw material stock resulting in high storage cost. The object of this research is CV. Pabrik Mesin Guntur Malang,an industrial water pumpcompany which is having difficulty in controlling raw material stock so that it often experiences abundant stocks.So,the problem is how to make stock controli n order to reduce stocks a mount that will result in storage cost reduction. Production S ystem Just in Time applying Karban system, that has been being implemented this far by Toyota Motor Corporation, Japan, is proposed to be implemented in that company as well in order to reduce prevailing inefficiency result from this existing problem. By applying Kanban system as support for the Production System Just in Time, it is shown that the system is capable in reducing stocka mount by 77.56%f or GTR type water pump and 89.59% for GTO type water pump. While reductions of storage cost achieved are78.99% for GTR type water pump and 90.45% for GTO tlpe water pump

Abstract

PT. Berlina  Tbk Pandaan  is a company that  produce  already use plastic product  package. Some of its  product  are Nivea  bottle,  Lux shower  bottle,  packaging  of sheats  and the other  form variation. The processing to make it, need at least twice a process  of machine. All those  product through  some  operation  which  happened  a  long  way  material  handling  from  one  machine  to another.  As main product  facility  is through  the  the  machine  layout  can  be seen that  machine placement  still arbitrarily, and  it will  cause  product  current  longer so that  cost and  distance  fo rmaterial  handling also bigger.To solve this  problem,  we  have to  study  a theory  group  technology.  Major  point  f this theory  is  machine  grouping  become  machine  cell also  product  grouping  become  part family  so that,  later,  each machine cell will  produce a certain  of part family according  certain  criteria.  With the computer program called gtlaypc.exe, part family and machine cell can be know and use it for planning a machine layout.The result of machine  layout  planning  using  group technology  is  total  distance  27853,5  m per day and 18978  m per day smaller from the earlier  exiting  machine  layout  so  that the cost of material  handling  plan  Rp. 35109,3  per day more smaller.  Planning  the machine  layout  with the group technology  can minimalize of cost and distance material  handling

Abstract

Every company always tries to serve all customer's demand. This need a good planning and schedulling to keep flow production. PT Binarenata is one company which produce many kind of metal products. Currently, this company has problem in material handling of product and lack of another product. To solve this problem, this company made Master Produclion Schedule using disagregat method to duet he fluctuation demand. From analysis data can be found the number of worker with minimum cost in the next production planning is about 966 persons with cost about Rp. 49.431.714.000,00. Implementing this Master Production Schedule can reduce production cost about Rp. 5.829.363.807,00 or 76,3 %
