Item Analisis Pertumbuhan Balita Pada Posyandu Berbasis PC(Politeknik Negeri Batam, 2012-07-16) Zamilah, Maryam; KamarudinPosyandu is a government program that provides health services, one for toddlers. Usually the data and measurement data of children recapitulated on KMS. But with today's technology, the system can be made more effective if data retrieval and storage using computer. Then the analysis of infant growth in Posyandu based on PC designed to facilitate the data retrieval. In addition, from the results data retrieval can also display the toddler nutritional status, which is based on standard anthropometric assessment of nutritional status of children in the Minister of Health numbers 1995/MENKES/SK/XII/2010. System, divided into two main parts: hardware and software. The hardware consists of measuring height using ultrasonic sensors, weighing the body using the Load Cell, amplifies the voltage amplifier circuit for Load Cell and Arduino to process data. The results obtained have a percentage error of about 0-4% for weight measurement. While the ultrasonic sensor has a large percentage of errors when reading distance of 0-3 cm. Overall, the time for retrieval and storage of data using this system is faster than the process manually.Item Under/Over Voltage Relay Berbasis Mikrokontroler Atmega328(Politeknik Negeri Batam, 2013-07-03) Situmeang, Benny; Atabiq, FauzunQuality of power supply system in an electrical circuit is needed. Poor quality power supply may cause distraction and may even damage the system hardware/ electrical circuit. One form of the disorder is the under/over voltage. To overcome this we need a protection device that can detect the presence of interference under/over voltage and secure the electrical equipment. Under/over voltage relay based microcontroller ATmega328 is designed aiming to detect the disorder under/over voltage on voltage single phase 220 V 50 Hz. Voltage limits for nuisance under voltage is -5% of normal voltage (220V), whereas disruption over voltage is +5% of the normal voltage. and delay settings for under / over voltage is 5 seconds. The output of the relay is connected to the contactor, the contactor will disconnect the power supply in case of disturbances under/over voltage. From the results of tests performed, the relay under/over voltage ATmega328 microcontroller-based designed to work properly. Relay can detect disturbances under voltage and over voltage -5% +5% of nominal voltageItem Clamp-Meter Pengukur Arus AC Berbasis Mikrokontroler(Politeknik Negeri Batam, 2010-07-19) Dwitama, Tanu; Pamungkas, Daniel SutopoItem Modifikasi Mesin Pemotong Kabel di PT. Yokogawa Batam untuk Meningkatkan Akurasi dan Kecepatan(Politeknik Negeri Batam, 2013-07-04) Hidayat, Imam; Oktani, DessyItem Alat Pemutus Listrik Dengan Timer (Digital Time Switch) Menggunakan Atmega 8535(Politeknik Negeri Batam, 2010-06-05) Kusuma, Eva Erli; Suhaimi; Fahruzi, ImanItem Alcohol Meter Based of Arduino(Politeknik Negeri Batam, 2012-07-17) S, Rio Sintong Immanuel; Oktani, DessyItem Kran Wudu Otomatis(Politeknik Negeri Batam, 2014-01-16) Pratama, Canggih Rian; Ridwan, RidwanAt present the deveploment of technology is growing very rapidl., Almost all surveillance conduct by human done by macnhine or electronic device. for example, monitoring the tap water for ablution and many tools in control and controlled by humans. During this manual ablution taps used by humans often goes wrong is often forgotten to shut down or close the water tap. at this final project to create a tool that can facilitate us in controlling the faucet, the faucet atumatic ablution. in principal it works is very simple. This tools use infrared sensor as the input signal that can detect whether there is or not a human hand under the water faucet. Ablution taps are used as a substitute for ablution taps manually replaced with 3⁄4 inch solenoid valve which is modified into automatic faucet ablution. This faucet infrared sensor signal received from the relay and a 12V DC source, so that tool is easy to use by anyone and is very easy to use, especially in the ablutions.Item Desain Buck-Boost Converter untuk Pengisian Baterai Telepon Seluler dengan Memanfaatkan Putaran Roda Sepeda(Politeknik Negeri Batam, 2014-06-06) Lumbantobing, Nengsi Kasmani; Gozali, M. Syafei; Sani, AbdullahTo reduce the risk of battery power quickly decreases when listening to music while biking , then a means of charging cell phone batteries can be used for charging the mobile phone battery when away from power source . This study aims to design a buck-boost converter for mobile phone battery charging by utilizing wheel rotation , so it can be useful for bike users to perform mobile phone battery charging while away from sources of electrical energy and reduce costs and time to generate generator used at the time mobile phone battery charging . For cell phone charging on the bike requires dynamo as a generator . The voltage output of the bicycle dynamo is AC then the bridge rectifier to function is converting the AC voltage to DC output of the bridge rectifier and an input for a buck-boost converter circuit . From the results of the testing of the tool can be made on the attached load values prior to voltage is 5 volts and the voltage value after the load attached is 4.25 volts with a current that varies according to the wheel rotation . To ensure that the incoming voltage to a cell phone battery Arduino awake then used as sensors in order to monitor voltage and current voltage and current to the cell phone battery with a graphic display using Labview software.Item Traffic Light Penyeberangan Anak Sekolah Berbasis Programmable Logic Controller (PLC)(Politeknik Negeri Batam, 2009-06) Syafrijal; Zulafandi; Zaman, Kamarul; Pamungkas, Daniel SutopoItem Robot KRI “Barelang 5.1” Manual(Politeknik Negeri Batam, 2012-07-06) Wathan, Muhammad Lalu Hifzul; susanto, susanto
