Abstract

PT. Industri Sandang Nusantara Pata! Secang Magelang is some factory that regarding in manufactur sector which thread producting. For this time the factory have a problem with stacking same kind of product and in the other way less  another product. This case cause that factory use product scheduling based on experience and reckoned of selling in last period.  Connected with this problem, the  case is how to make a good  schedule in order that  factory could be completing consumer demand and decided some main product schedule with simpleks methode.

Analyst result get that  demand fluktuation for R 30/1,   PR 30/1  products use Moving Average Linear Trend (3) methode, R 24/ 1,  R I 11,  PR 40/l products using Moving Average Linear Trend (5) methode, PR 45/l  product using Linear Regression methode. Value analyst with based on forecasting result for future 12  periods,  supposed that factory will  pay for Rp.  460.340.000,• After applying Linear Programming giftotal cost Rp. 450.164.576,-.  Thrifting Rp. 10.175.424,- or 2,2%.   Sensitivity analyst made cost to be Rp. 448.651.040,-,   thrifting Rp.  11.688.960,-    or 2,5%  at the number of regular employees 66 persons.
