    Design of Biogas Power Plant is a research campus to meet the needs of new renewable energy and environmentally friendly. Then conducted the research with engineering scale biogas power plant in the area of domestic Sei Temiang Batam. By utilizing livestock waste contained in the sei temiang, Batam, so we try to build biogas power plants around the farm area. In the process of implementation, this design, the location where digester for decomposition can not be far from the ranch, because the source used is cow dung. And for a mixture of water, the water used is fresh water, or use the nearest water source around the farm area. Temperature to be one important factor for the decomposition, because the temperature is well open to the biogas production ranged 30-55 C , therefore the digester should be placed in an open space exposed to direct sunlight. Prototype plant uses a mixture of cow dung and water (with a ratio of 1:1) as much as 576 liters. Volume of gas produced as much as 624 liters. This gas volume can be used to power electricity for 35 minutes with a power output of 700 Watt

    Rancang Bangun Auto Transfer Switch Menggunakan Triac
    (Politeknik Negeri Batam, 2017-02-10) Maulana Dalimunthe, Muhammad Arief; Gozali, M. Syafei
    The availability of electrical power from utility sometimes disturbed, be it from internal of the system like equipment failure or from external of the system like nature phenomenon, so it will obstruct daily activities. However if the activities are urgent, so disturbance of electrical power is not allowed. It cannot help but must use backup supply that generally obtained from diesel generator that usually called genset. Despite that, turning the genset on manually there will be a rather long time delay so it is not too effective if the activities need to handled fast. Therefore this research is useful to solve that problem. This device uses three modes, those are Manual PLN, Manual Genset, and Auto. Manual PLN and Manual Genset mode, the transfer of electricity supply done manually. Meanwhile Auto mode transfers electricity supply by detects which supply available and then transfer it to load. The detection done by converting PLN’s AC supply to DC then directing it to Arduino microcontroller which will process incoming input then triggers TRIAC PLN or TRIAC Genset based on the status of PLN’s supply so power will flow to load pass through the TRIAC. This device can do the switching with good timing accuracy that matches with the programmed delay in microcontroller with nominal current 6A.

    Simulasi Navigasi Kapal : Point To Point Dengan Gps
    (Politeknik Negeri Batam, 2017-02-24) Istiana Putra, Eka; Risandriya, Sumantri K
    Ship is a marine transportation that used for connect the islands. So that we need a reliable navigation system for easy control. Autopilot is one of the alternative driver to run the ship automatically. By using electronics coordinate point that can determined by GPS module (GY.NEO6MV2). With the coordinates point, the driver can automatically determine the direction of the ship. In the control, the point coordinates in the input through the keypad and the results will be displayed on the LCD. Arduino Uno will process the goal with a predetermined mathematical formula to get the point coordinates of the destination of the ship. After that two propeller ship propulsion will determine the position of the destination. And the ship will change the position and heading towards the goal. To control the propeller, use Driver Monster moto shield Arduino (VNH2SP30) as controlling propeller speed and direction of rotary propeller. All the system is set by Arduino, so we need the right program in control. From the observation can be obtained the data input of the destination, tilt angle, distance goal, heading the ship, and the movement of the ship propellers.
