    Pengontrolan Rumah Pintar untuk Sistem Manajemen Daya Berbasis Web
    (Politeknik Negeri Batam, 2008-06-04) Helen, Mei Rani; Gozali, M. Syafei; Wijanarko, Heru
    The diminishing of natural resources at this time could have an impact on the need of electric energy in human life. The use of uncontrolled electrical energy can cause damage and more burden on the house so it must be kept well controlled. Currently, the technology to make electrical energy savings has been much to the stage of controlling electrical equipment with the system remotely. However, from that system we must know the equipment is controlled in accordance with the commands given and to get the information it needs a feedback such as indicators that become parameters of control success done. On this system using a Microcontroller device that will be the center of the control of data processing sensors and NodeMcu as a data sender device to the web. data transmission communications used are I2C and wireless communications, then all data sent will be received and stored by Raspberry as a system server. To perform such control can be done through the web so, that electrical appliances at home can be controlled remotely.

    Perancangan Sistem Pengukur Kesejajaran Tinggi Dua Benda Berbasis PID
    (Politeknik Negeri Batam, 2015-01-20) Wicaksono, Guntur; Fahruzi, Iman
    In measuring the height alignment of two objects (flatness sloof leveling and foundation) a builder requires a small hose that had been filled with water in it, the pull of the point to be measured is then pulled thread as a reference height that occurs cutouts leveling horizontally (law related vessel Archimedes). With the measurement method, requiring long hose if it would measure 2 pieces distant point and of course with plenty of water volume and requires a long process so that the water be quiet and the measurement can be done. Therefore, the authors make a tool to replace the function of the tool digitally, by utilizing light. According to the nature of light that light travels in straight then this tool authors utilize the functionality of laser light that can reach remote places with light focus on one point. Then that the laser beam can emit light with a straight horizontal earth's gravity is required The parallel arrangement with the Earth using an accelerometer sensor and servo motors. To set the desired height in the tool takes the motor and an encoder sensors as feedback on the PID system to be created. Based on the results of tests performed, obtained good results. By using the value of Kp = 2, Ki = 0.01, Kd = 1, SP = 250 and Ts = 5 is obtained Rise Time = 593 ms, Peak time =706 ms, and steadytime = 932 ms. Then the range of the accelerometer sensor g on better response by using ± 16g.

    Smart Monitoring Temperatur & Kelembaban Ruang Server Berbasis Web Menggunakan Raspberry PI
    (Politeknik Negeri Batam, 2017-07-07) Rinaldi, Rio; Kushardianto, Nur Cahyono
    This Research introduces wireless sensor of wemos dht shield where can read the condition of temperature and humidity. Build a system and network that will be functionally as monitoring condition of server room temperature and humidity. System visualize the temperature and humidity data on a web based program with real time graph of highcharts. The Log data of temperature and humidity will be recorded in MySQL DBMS. Recorded log data displayed in datatables structure. The purpose of this system is to avoid a computer server from overheat were caused by high temperature in server room and also caused by a failed air conditioner. Raspberry Pi is a micro controller device were functionally as a web server and processing the data received from wireless sensor. System can provide a notification into smart phone with whatsapp application. Registered user in whatsapp application can do some command and raspberry will processing the command with youwsup service. This system can provide fast response when it happened the temperature rise to the limit of the standard server room health.
