Abstract


The domestic plastic manufacturing industry is currently experiencing continuous development. Therefore, competition in the plastics manufacturing industry demands that they are always ready to improve their performance and productivity. PT. XYZ is a plastic manufacturing company that faces problems regarding a lack of productivity levels. There are three work stations at PT.XYZ (Mixing, Injection, and Assembling). The mixing department is the department that has the lowest average productivity percentage, namely 83.3%. Efforts to increase productivity are carried out using an ergonomic approach, namely the time and motion study method and combined with quality tools in the form of check sheets, Pareto, fishbone and 5W+1H analysis. Monika Kussetya Ciptani (2001), the use of the time & motion study method which is integrated with the Activity-Based Costing (ABC) method in terms of cost assignment, will affect the Company's productivity and cost efficiency. From the results of the 5W+1H analysis it is known that the decrease in productivity occurs because there is no standard time measurement for the mixing process. Then there are recommendations for improvement by measuring the standard working time of the mixer operator . In the process of time and motion study analysis it is known that the three elements of the mixing workstation are cleaning the mixer tube, mixing, and packaging. From the calculation results it is known that the normal time is 0.5072 minutes, the allowance is 7.98% and the standard time is 0.5511 minutes. After corrective action was taken, there was an increase in productivity of 16%.

Keywords: productivity, ergonomic, time and motion study
