    (Politeknik Negeri Batam, 2017-05-16) Ghafur, Muhammad Abdul; Istardi, Didi; Pratomo Ariyanto, Nugroho
    Power source is a device that serves to supply electrical current in type of welding SMAW (Shield Metal Arc Welding), an example is DC-400 machine. The output current of machine is set using a knob on the output control panel in order to generate heat as needed welding. Along with the development, welder realized that there are limitations in the way of controlling current on the machine. Distance control that requires users to go directly to the machine caused inefficiency in work. Therefore, we need a controller for adjusting the output current from long distance. It is necessary to create "Current Control Device for DC- 400 Machine Based Microcontroller and Android". This device can adjust the output current value from long distance and wireless which is a microcontroller as the central controller and android as the input source. From the results of research, the greater value of R1 in potentiometer is set, the greater welding current is generated. The average error between the welding current using the knob and remote is 4.65%.

    (Politeknik Negeri Batam, 2017-05-15) Brian Trenggono, Okto; Febriansyah Juwito, Arif
    Vigilance is the important things that required to create a security. But sometimes people remiss and less their alert to matters that relating to the security. Security it means a condition that free from dangers, this term is used with relation to the crime, all of accidents, etc. Security is the important thing for a home, where the people forgets to lock the door or someone had locked the door but hiding their key in some area around the houses that is not known by others just for avoid that key will be lost when they are not in home. If this continuous it will be lead to the unsafe situation.One way to resolve this problem is with control system and security monitoring using android. With this devices if the user forgets to lock the door, users can directly control their door lock on the house and at the same time users can monitoring all of the existing security sensor using their own android smartphone. In order to use this devices, android smartphone must be connected to the internet. Users only need click or unclick the button on the application for lock or unlock their door lock. Smoke sensor and pressure sensor that is located on the door lock detects any threat or danger, the system will immediately send the notice to the android smartphone in real time.

    (Politeknik Negeri Batam, 2018-01-03) Arianto, Deni; Aisyah, Siti
    Nowadays, communication system development had spread rapidly. This condition, made human job easily to monitoring and to control many things especially in industry era. At Batu Ampar diesel power plant, one of the most important parameter for keep fuel systemat settling tank level. Due to manually to fill the fuel to settling tank by operator, it made non effective because the distance between settling tank was so far from control room.Thiscondition can be removed by added ultrasonic sensor to measure the level of MFO fuel. After that, the data from sensor will transfer and process into microcontroller. We alsomade human interface system to display settling tank level by using LabVIEW. Based onresearch and analysis, we can took conclusion that these system will be more efficiently if parameter to monitor settling tank about 5 until 50 m. But it would be unefficient if theparameter to read the settling tank level more than 50 until 80 m because there was delay about 4 seconds. To switched on and off the transfer pump, happened delay along 2 seconds from 5 to 50 m. And for the parameter between 50 until 80 m, it took longer delay about 40 seconds.

    Sistem Pergerakan Point to Point Mobile Robot dengan Kontrol Posisi Motor DC
    (Politeknik Negeri Batam, 2018-07-20) Danil, Jufrika; Soebhakti, Hendrawan; Pratama, Rizky
    Mobile robot is typically one of numerous types of robots, as it is the foremost used for Differential Wheel Drive that offers low cost. However, regardless of the type, the main issue from mobile robot is related to it’s drive system and it’s simple manually controlled with on-off controller. Furthermore, the automatic drive is necessitated to move to targeted points or positions with ease. Thus, implementing Forward Kinematics method which is received from time discrete feedback and inverse kinematic controlled by PID with feedback of internal encoder at DC motor is supposed to make robot moves automatically. This experiment shows that the driving control system can move the position of the robot where the average error for its movement/motion is 11.9% with respect to X axis, 11.4% with respect to Y axis, as well as 15.4% towards Theta with percentage of successful movement reaches 87.08%. Additionally. The error may due to slip of the wheels while moving as well as system of position’s feedback and the direction that is only obtained by time discrete.
