Productivity Analysis on Batik Production Line Using Objective Matrix (OMAX) Method

摘要

The competition of industry was increasing with Batik industry as one of the fastest growing of non-oil and gas indus-try. CV. XYZ is a company in the field of batik industry. In 2017, there was a fluctuation of sales and there was a gapbetween production and production targets. Based on data, 10 out of 12 months during 2017 did not meet productiontargets. Therefore, this study aimed to measure the productivity that could be used as an evaluation and then madeplans to increase productivity. In addition, the base of support to increase productivity was ergonomics. In this re-search, productivity measurement was performed using Objective Matrix method. OMAX is a partial productivitymeasurement system developed to monitor productivity. The object studied in this research was the productivity levelof the cutting work station because it was the first work station of batik production process and considered as the re-presentation of other work station. The subjects were 2 production department leaders and 6 cutting work stationworkers. The result was the lowest value of productivity occurred in September with a value of performance indica-tors of 62.60. The lowest productivity index occurred in October to November of 9.8%. The main factor causing lowproductivity was the empowerment of labor and the use of work time that was not optimal. Increasing the empower-ment of labor and the use of work time should have been complemented with a proportional improvement where theneeds of labors should be considered.
