Abstract

A bicycle control system has been made using the PWM principle to adjust the motor speed byusing a distance sensor as a safety system on the highway. The background of this research,electric bicycles have still not installed a safety system that directly connects motor speed usingthe principle of Pulse Width Modulation (PWM). The control system that is designed are addedan ultrasonic sensor on the front of the bicycle that serves to measure the distance of the rider'sbicycle with other vehicles. Variation of the specified distance is equal to ? 1 meter, ? 2 meters,? 3 meters, and > 3 meters, so the risk of accidents on the highway can be decreases. Thepurpose of this research is design and build a control system using the PWM principle toregulate the rotation speed of the motor and safety systems on electric bicycles. The results ofthis research are in barrier-free condition, electric bicycles can drove with average maximumspeed of 28 km/hour. The speed of an electric bicycle that is affected by the front ultrasonicsensor at a high speed at a distance of 3 meter, 2 meter and 1 meter, respectively; 20.6km/hour; 15.5 km/hour; and 5 km/hour. The right ultrasonic sensor has succeed to activatingthe buzzer at a distance of ? 100 cm.

Abstract

The low students study results in the learning activity using mechanic measurement devices is a background of the problem, caused by teacher’s teaching method is still using a conventional approach which is just a verbal lecture without using computer media, it can be seen from student’s low study results. This research aims to find out the level of students’ comprehention on the subject material with the number student of 30. The research is designed in three stages which are pretest stage, learning stage, and post test stage. Data collecting method to be used are documentation, dan test method. Instruments to be used are test and questionnaire. This research is a descriptive research that had been done on the tenth grade student of TKR SMK Karsa Mulya Palangka Raya tahun ajaran 2014/2015. The student achievement level reached 83,4%. It means that learning process using tutorial video on the subject material Using mechanic measurement devices is achieved as per the achievement level criteria of learning process which is 80-100%. It can be concluded that learning model CAI (Computer Assistance Instruction) in the form of tutorial video can be used as an alternative in delivering subject material Using the mechanic measurement devices.
