DESIGN OF INTEGRATED INDUSTRIAL SYSTEM 1 LABORATORYINDUSTRIAL ENGINEERING DEPARTMENTFACULTY OF INDUSTRIAL TECHNOLOGYISLAMIC UNIVERSITY OF INDONESIA2015CHAPTER VIMICROMOTION STUDY
6.1. Practicum Objectives1. To know the Micromotion Study method on the application of standard time with analyzing the working movement elements.2. Able to identify work elements and able to analyze the effective and ineffective work elements on certain job.3. Able to make improvements on movement elements which are not required or ineffective in order to perform facility or work station layout setting.4. Able to calculate the standard time by studying the movement elements with the help of movie recorder.
6.2. Practicum Tasks1. Observing and analyzing the movement of the working operations based on video record assembly.2. Calculate the standard time by using motion elements table.3. Determine the standard time of each element of the overall standard of work and working time in accordance with the SOP work operations.
6.3. Output6.3.1. DescriptionMicro motion Study is a technique that used to analyze in detail the worker movement (Wignjosoebroto, 1989). This technique was first developed by Gilbert in motion study techniques (Maynard, 1971). Activities are included in micro motion Study is a video recording and record the time (Barnes, 1980). In this practicum, we analyze in detail about the worker movement that assembly a sport car sedan. In this practicum we did the activity twice that did by the worker, the first activity show the initial layout of the work station and the second activity show the propose layout of the work station. After that we have to analyze about the differences in both initial and propose work station.In the given case study, can be seen that the operator at station, he assembly Tamiya 4WD. Tamiya have so many part and the parts is consists as below:Table 6.1. Layout ExplanationBOXJARAK (CM)JARAK (INCHI)DESKRIPSI

A. Initial LayoutAnalysis micro motion study activity used to analyze in detail the operators to do the work in relief so that it can get the standard for doing his job. The analysis micro motion study conducted in this research is the operator do assembles Tamiya car. Work done by one of the male with the work stands. The operator Tamiya location and distance of the layout of each layout to be seen on the figure below:
Figure 6.1 Initial layout
Figure 6.2 Initial Layout (operator to box)
From the video that we got from this practicum, we can identify the innefective and effective motion of work. Those are :Table 6.3 Table of Motion WorkMotion DescriptionMotion of workIdentification

Standard Operation Procedure explain about the step that will be done in assembly Tamiya with operation and work station that using the standard time that have established.
6.3.3. ConclusionFrom the result left and right hand map we conclude that total standard time for assembly this Tamiya is 72.666 seconds. And there are some ineffective motion that operator has been done such as avoidable delay, position and etc.
