Item Sekuter Keseimbangan Beroda Dua Berbasis Mikrokontroler(Politeknik Negeri Batam, 2013) Kennedy, Kennedy; Risandriya, Sumantri KScooters balance is a scooter that has two wheels on the right and left are not balanced if in the absence of control systems and sensors tilt. Scooters is the development of models of inverted pendulum were placed on top of the train wheels. Balancing two- wheeled scooter requires a method of maintaining control of the scooter in a position perpendicular to the earth's surface. Needed to maintain a balance scooter accerelometer ADXL345 sensor and gyro IMU 3000 to detect tilt and angular acceleration of the scooter. Driver of the scooter uses two DC motors. Methods of control that are used for the balance of the scooter is PD control system. Then control system that has been implemented in the microcontroller. control signal or output from the PD control in order to control a DC motor scooter can stand perpendicular to the surface of the earth. Tests on the robot in balance defensively using PD control method with parameter kp = 1000 kd= 500. And the result scooters maintain position perpendicular to the earth's surface and oscillating between -3 ° to 3 °.Item Kendali Mesin Pelontar Bola Tenis Menggunakan Mikrokontroler(Politeknik Negeri Batam, 2010-06-25) Setiadi, Firman; Efendy, Hanis; Soebhakti, HendawanItem Proteksi pada Instalasi Listrik dengan Elcb Elektronik(Politeknik Negeri Batam, 2016-06-17) Bimasena, Kevin Koes; Juwito, Arif. F; Hasnira, HasniraSecurity factor on electricity installation is the main consideration, because of function to prevent the damage on electronic devices caused by short-circuit and leakage current. In general this circumstance used MCB (Miniature Circuit Breaker) and ELCB (Earth Leakage Circuit Breaker) which assembled in house installation system. This research aims to created installation protection system with ELCB 3 Ampere. This system used current sensor to read the current that is passed by phase and neutral, TRIAC serve as switch to cut off and connect the current from load. Microcontroller serve as trigger gate from TRIAC based on input data from current and voltage sensor. Of the test result if current flowed over 3 Ampere, TRIAC switch will cut off.Item Prototipe Alat Pembersih Jendela(Politeknik Negeri Batam, 2012-08-05) Dirjoko Sunandar, Mohamad; Riyad Firdaus, Ahmada window cleaner widely used in a life and in the industrial word. Because every day the glass windows are often dirty because of dust. especially a windows in tall buildings which may not be cleaned every day by humans. The actuators to move the tool to clean the windows is a DC motor. Where in this case the DC motor is easier in use and the cost is relatively cheap. The tool to clean the windows fitted with RTC module. This module RTC serves as a timer to make the tool to clean the windows works automatically on a periodic, such as once a week to the window glass cleaner. The tool to clean the glass window is a wiper (which is usually found on the windshield). To control a direction of motor rotation is used a DC motor driver, Motor driver serves to change the polarity of the DC motors that can rotate right and left. Motor driver using a Relay And in the process is used microcontroller, the microcontroller will process all the data that we put, such as: schedule tool to clean the windows will work. Obtained according to the study of books, internet and direct testing to this prototype can clean the window periodicly with timer from RTC. Time required to clean up is two minutes.
