No full textPT. Indonesia Nippon Steel Pipe is a company engaged in manufacturing, which produces components for two wheelers and four wheelers. Components produced for two-wheeled vehicles include: front fork for PT. Showa Manufacturing Indonesia (SIM), Mufler pipe for PT. Yutaka Manufacturing Indonesia (YMI) and others. To the four-wheel drive are door impact beam for PT. Astra Daihatsu Motor (ADM), rear axle for PT. Inti Ganda Perdana (IGP) and others. For YMI mufler pipe produced in sub division yutaka. pipeline fabrication process flow are: Cutting, Bothside, Punch, and Packing. The pipe produced directly sent to the customer. But after that, there are complains from the customer. This caused by the number of pipes those are not exactly 50 pcs. Sometimes the pipe-packing in less than 50 pcs.
Then came the idea to create a device or a system that is expected as a solution to the problem. The idea is to create a new box design. The design is to add an aluminum plate to the rack and draw with Autodesk Inventor 2010 software. The aluminum sheet has 50 holes with a diameter of 30 mm, adapted to the quantity of orders by the pipeline customers. Once the design is finished, then followed by the process of aluminum machining sheet using a CNC machine. At the assembly in the box, nuts bolts add with cable poles tis as a binder between the shelves to the wall box.
Once finished, aluminum racks are assembled, and a trial is performed with the new box. The result was compared between with the old box. From the experimental results, the process of packing with the new box showed a reduce errors when mufler pipes are filled into the box. Additionally cycle time can be reduced by 12%

ABSTRACT
The problems found in male students of class VIII2 of SMP Negeri I Rambah Rokan Hulu District. that the results of the sprint run achieved by students are still not optimal, this is because the practice of watching too much does not make students take it seriously. Students are lazy, students are bored, students are stiff. From the students 'running techniques such as swinging their hands with foot movements less harmoniously, besides the coordination of the students' running movements were not maximal, so that when students ran, the coordination between swinging hands and feet still looked stiff and made the student's running speed reduced, beside seen from the leg muscle strength that students have, so to create the maximum running speed results, students always have to practice the variation training method and the strength of the leg muscles. The aims of this study was to determine the effect of the variation training method, leg muscle strength on the results of the 100-meters sprint in class VIII2 of SMP Negeri I Rambah Rokan Hulu Regency, Indonesian Country.
The type of research is Pseudo Experiment. The population is all male students of class VIII2 of SMP Negeri I Rambah, Rokan Hulu Regency with a population of 14 male students, with the sampling technique being total sampling or taking the entire population of male students of class VIII2 in SMP Negeri I Rambah, 14 people in Rokan Hulu Regency. The instrument used in this study was to measure leg muscle strength by using the leg dynamometer test and to measure the run of students a 100-meters run test was conducted.
The results of the study and analysis of the data showed that (1) the form of training methods for the variation of limb explosive strength significantly affected the increase of 100 meters runner effect of 8.11, it can be concluded that there was influence of leg muscle strength on the results of 100 meter sprints in male students class VIII2 State Middle School I Rambah Rokan Hulu Regency (2) the form of exercise using the power of explosive limb muscle power has a significant effect on the ability of the 100 meters running 9.07 (3) there is a difference in the effect of variation training with the explosive strength of leg muscle 0.96.
