Item Meteran Air Prabayar Berbasis Smartcard(Politeknik Negeri Batam, 2013-06-03) Triwandana, Jati; Oktani, DessyIn the present era, the development of technology, water meter in the residential- housing, buildings, ports, airports and others in Indonesia are still using water payments at the end, then on this occasion the author is trying to create an innovation-based Prepaid Water Meter smartcard. The purpose of the creation of this tool is to reduce HR (human resources) required by the water service provider. The tool is divided into two parts, namely a tool that serves as filler RFID Card (owned water services provider) and a tool that serves as RFID reader card prepaid water meter at the same time (being in buildings that use water). Through the interface of Visual Basic water flow data that has been purchased by the consumer is sent to the device through the RFID Card RFID Card filler. Then after consumers enter the data contained on the RFID card prepaid water meter to existing customers in place, then the prepaid water meter opens valve solenoid valve so that water can flow further discharge of water that flows will be measured using a water flow sensor, when water discharge was similar to that measured water discharge data purchased the solenoid valve is closed so that the water can not flow. Automatically when the consumer wants to use water more then the consumer must replenish its RFID Card.Item Perancangan Robot Mobile Penjejak Dinding Koridor dengan Kendali Logika Fuzzy(2014-06-06) Silitonga, Yeni Frida; Sani, Abdullah; K, SumantriEnvironmental conditions can not be predicted pose complex programming by using conventional controllers . Fuzzy Logic is one of the modern controllers are able to work well on systems with non - linear design offers ease of program because it does not require a mathematical model of the process . Input Fuzzy designed with 3 input sensor data that is left , right sensor , and front sensors . Membership function has three inputs with 27 rules . Fuzzy input is processed by the microcontroller ATMEGA 328 with Arduino ROMEO program that will eventually generate a PWM signal used to control the speed of each motor . Type Fuzzy Logic is the method of defuzzification mamdani with COA ( Center Of Area ) . This study aims to design a mobile robot that can track the corridor wall with a feedback control system based on fuzzy control is implemented in the form of hardware and software (microcontroller system) . Fuzzy logic is used to determine the angular speed of the robot . By knowing the angular speed of the robot at any time , the linear speed of the wheels of the robot can be determined . Linear speed of the wheels of the robot will adjust the amount of duty cycle PWM signal on each motor , while trace ( guidance ) in the form of two walls that can be analogized as a corridor . The experimental results show the robot can walk along the corridor with the largest average error of 20 % to the center line corridorItem Elektronik Peggle Game(Politeknik Negeri Batam, 2009-06) Syaukani; Wikanta, PrasajaItem Sistem Pemisah Barang Berdasarkan Berat Berbasis Mikrokontroler(Politeknik Negeri Batam, 2012-07-16) Iswahyudi, Sugeng; Oktani, Dessy; Fitriyah, QoriatulItem Sistem Monitoring Pemakaian Daya listrik(2010-07-19) M. Syaiful; Rozzy, Handoko; Boni, Rahmat; Istardi, Didi"The monitoring system wind turbine" is a device designed to ease in knowing how much current, voltage and power generated by a wind turbine, where we use a microcontroller as the main controller. Before the data entered into the microcontroller, the data is first read by the sensor 712 ACS. The data have been processed in the microcontroller will also be sent with RS 232 serial communication to the Personal Computer, which then displays the value of current, voltage and power by using VB software. In making this tool voltage source, the ACS current sensor 712, voltage sensor and the ADC on the microcontroller is the most important thing that must be considered because it will affect the accuracy in reading the current, voltage and power.Item Smart Building (Prototype Alat)(2012-08-07) M. Bahrudin; Adytia, DarmawanCurrent technological developments increasingly facilitate the conduct of human activities. But also adds many new problems such as high rise buildings that have a lot of ground, making it difficult to monitor the existing space in the building. To facilitate such work, then designed a tool for controlling and monitoring electric appliance in the office/building. This tool basically consists of two electrical devices are controlled via rs485. In the monitoring system consists of several electronic circuits which function light sensor for monitoring lamp, a voltage sensor function is to monitor the voltage-controlled, microcontroller (Arduino) serves as a data processing unit, in order to control and monitor the data is then sent to a computer for display to the application acquisition of data via RS-485 as a communication of some of the microcontroller to the computer. While the control system consists of an electric circuit breaker in which there is a relay and relay driver circuit, this circuit AC current will decide when it gets a signal or data from a computer and processed by a microcontroller. In making this tool a voltage source, a light sensor, voltage transformers, communication RS-485 and ADC on the microcontroller is important to note because it will affect the accuracy in reading the voltage condition, lights, and RS-485 communications. For feedback from the controlled device used a light sensor and voltage sensor. Sensor voltage is used to detect the voltage on the device being controlled, while the light sensor is used as a detector lights. To find out the control data input from the user database is used as a control data storage media.
