<![CDATA[The purpose of this research are: 1) Knowing the exhaust gas emission test result from Honda Brio Satya with variation of fuel 2) Knowing the type of fuel that produces the lowest exhaust gas emission value. This research is using experimental method. This research was conducted in the automotive workshop of SMKN Udanawu Blitar Regency. Test media is a Honda Brio Satya type E 2017. The emission test used QROTEC QRO 402 gas analyzer. The results show that: 1) There is influence of fuel type to vehicle exhaust emissions, both at idle and intermediate rotation; 2) The average of CO gas emissions at idle rotation with fuel of each premium, pertalite and pertamax are 0.026%, 0.023% and 0.003%. The average of HC gas emission at idle rotation in each fuel type are 87 ppm, 86.3 ppm and 30 ppm. Thus, pertamax fuel produces the lowest level of exhaust emissions. The third fuel type still meets the threshold of motor vehicle emissions threshold in accordance with PERMEN LH No. 5 of 2010 so it is worthy to be used as an environmentally friendly learning media.]]>

<![CDATA[There are many important reviews about the flow characteristics in the body of the racing bike helmet caused by the relative motion of the air along the Trailing Edge shape. The lines formed in such a way in the speed field will form a streamline stream so that the lines are in line with the flow at each point in the flow field. Thus, the streamline will form a pattern of airflow around the helmet. This aerodynamic characteristic study was performed on time meter helmet body visualized numerically using Computational Fluid Dynamics (CFD) with Solid Work Flow Simulation software. With variation of Trailing Edge 25 mm, 75 mm, 125 mm. Urgency research about helm time trial is believed to provide information about the flow that occurred. The result shows that the drag coefficient reduction that occurs on the cut variation of 75 mm compared with other variations on the Reynolds number 1.16 x 105 of 0.395.]]>

<![CDATA[This research was aimed to find out the improvement of cooperation and student learning outcomes by implementing active learning strategies based on the independence and activeness (KEMANTI). The design of this research adopted Classroom Action Research. The learning strategy of KEMANTI was applied in SMK Muhammadiyah 1 Salam Magelang. The stages of research resulted in the improvement of student cooperation can be seen from each aspect of cooperation which includes aspect of giving idea or opinion up 30%; accepting the opinion of others up 50%, carrying out the tasks given by the group up 30%, the nature of helping others up 40%, and the last aspect is concern for the difficulties of fellow group members up 50%. Improvement of student learning outcomes is shown by the value of effect size 3.2. The difference in learning outcomes uses t Test which shows that t tab is 4.9 in cycle I and t tab is 16,9 in cycle II. Test Results t post-test cycles I and II t hit> t tab is 15.00> 2.0. The conclusion of the t test results is that there is a difference from pre-test and post-test in cycle I and cycle II after being given an active learning strategy of KEMANTI.]]>

<![CDATA[This study analyzes the loading on the model wheel-253 size 6.5 x 15JJ based on SNI 1896: 2008 with finite element method. This load analysis tested the resistance to dynamic radial fatigue on alloy wheels by using load simulation with quasi-static failure mode approach ie failure mode which is independent of time, and its resistance to failure is expressed with strength. Test wheels are said to fail if there is crack (crack) by giving the liquid penetrant. Crack conditions in the simulation can be seen from the stress and elastic strain. The equivalent elastic stress and elastic strain values that occur on the rim must be less than the Ultimate Tensile Stress (UTS) and the elastic strain at break. The properties values for Aluminum A356-T6 material for UTS of 228 N/mm2 and strain elastic fracture values obtained from a plastic material strain of 0.059 m/m.]]>

<![CDATA[One of the method that can be used in car maintenance is Jishu Hozen that demands the driver to be able not only riding the vehicle but able to maintain it. In order to increase people understanding to Jishu Hozen method especially engineering vocational student we could use Jishu Hozen method to more enjoyable form which is in form of android-based educational game. Game can implemented android application that mostly people and college student has android mobile phone. The purpose of this research focus on to create a method in transmition maintenance using Jizhu Hosen method that implemented android-based game. To fulfil this research purpose we use Information Gathering, designing Jishu Hozen method into android base application to test it. To test the game we spread a questionnaire to 30 engineering college student. The result validity and reliability show that the game is appropriate. The result from questionnaire show that the students’ level of satisfaction upon the game is higher. Besides that, there are differences on students’ knowledge before and after using the education game that tested using paired sample t-test.]]>
