Abstract

The aim of the study is to find out the measurement of operator level labor productivity in X packaging workstation company. The problem of the study is Measurement of Workforce Productivity Level Operator Using the Work Sampling Method. The study of work measurement is intended to determine the standard / standard time of work and can provide good decisions in determining the optimal number of workers. the method use is qualitative descriptive data in the form of words, pictures, and not numbers. These data can be obtained from interviews, field notes, photos, videos, tapes, personal documentation, notes or memos, and other documentation. the result of the study are 1)The Average Earning Percentage for each worker 2)For worker 1 is 0.8978 for worker 2 is 0.8843 for workers 3 is 0.88453) The standard time required to complete one work cycle (completing one unit) is 0.188 hours4) The Number of Actual Workers = 3 people5) The number of Standard Workers based on the calculation results is 4 people.

Abstract

In the last 10 years, competition between companies (business entities) has become increasingly sharp. The company continuously strives to reduce production costs and improve the quality of its products. The development of cooperation with suppliers is one of the efforts made by many companies to achieve this goal. Currently no single company can manufacture its products without the involvement of suppliers. Collaboration in determining policies for supplying and manufacturing companies in terms of supply creates a production system network ( PSN) that has a collaborative relationship pattern . This relationship creates an innovation in the manufacturing system which certainly brings benefits to both parties. Silver, Pyke and Peterson (1998) suggested the need for coordination in determining inventory policies between suppliers and manufacturers, with the aim of being able to make savings on the aspects of setup costs per unit, ordering costs per unit and transportation costs per unit. Determination of inventory policy as a result of cooperation between suppliers and manufacturers creates the need to determine the combined lot size. The research objective is to obtain a combined lot size determination model that takes into account the aspects of reducing setup and improving production quality. The results of demand forecasting in the future are the basis for calculations in production planning, inventory control and calculating the cost of procuring the most economical raw materials.
