Abstract

Optimization is an effort to maximize activities so that they are realized desired or desired advantage. Optimization in form Raw material planning can be defined as an activity which coordinated to achieve certain goals within a certain period of time. Raw material planning has an effect on operating costs, so that errors in inventory will reduce profits. Company Inventory problem, too much supply or even a shortage. Both of these conditions resulted in the emergence of this situation substantial costs. Therefore, it is necessary to plan the raw material inventory with the MRP method to analyze the optimal inventory level.The purpose of planning and planning is to plan and controlling the flow of material into, inside, and out of the factory thus the position of optimal profit which is an attainable goal. Material requirements planning is carried out using the MRP method whose application begins with forecasting the number demand / production for the future. By seeing material requirements planning, then inventory planning is carried out by using the Horizontal Planning method. From the results of Horizontal Planning produce optimal inventory planning.Keywords: optimization, planning, MRP method.

Abstract

In-depth observations have been made on the web printing process for newspaper production. Observations were made to identify problems related to the tension of the roll paper used in the production of newspapers. The problem of roll-paper tension is observed from the main material, the upstream process (Reelstand Unit), the printing process and its supporting units such as the wetting unit, inking unit and in the folder unit which is a contineous process. From observing the problems in the printing process, the causes and solutions to the problems were identified which were then used as an operating standard reference for the newspaper production using a web offset printing machine.Keywords—web offset printing machine, newspaper, paper tension
