    In general, cassava cutting machines are made by manual tools such as knive or scraper that need long time to do. Thin cassava cutting machine made to produce the same thickness of cassava chips and practice. The pressure motor which writer use is DC Motor for Power Window, and the cutter motor will work when the pressure motor touched cassava bowl. The product will measured by loadcell sensor, if it read 1 kg then the second DC Motor push bowl to the right and repeat by the secong DC Motor push the opposite way into the bowl, and if both bowls are full, so the third motor will move down equal the second bowl’s rack and so it is. All the motors will turn of if the pressure motor touched the limit switch which located at the edge the device. So, with this system the number of production capacity will grow faster and concise. This machine produce 5kg per 3 minutes in advance produce 5Kg per 15 minutes.

    Rancang Bangun Instrumen Akustik Pasif Pendeteksi Gelombang Bawah Air Berbasis Arduino
    (Politeknik Negeri Batam, 2017-12-22) Sihombing, Perdi Novanto; Analia, Riska; Lubis, M. Zainuddin
    The application of passive acoustic in marine can be used to ease the researcher for detecting the moving and static object in the water. The Fast Fourier Transform and wavelet is applied to the signal system in order to detect the noise and signal perform by object detected. The experimental results present the data got from koi fish and gourami fish in the plastic container which dimension is diameter 20cm and height 10cm. The data shows that the object can produce 13 sound patterns which koi fish has -15,66 dB in sound intensity while gourami fish has - 18,71 dB.

    Sistem Keamanan Loker Berbasis Gsm Module, Bluetooth Module Dan Reed Sensor
    (Politeknik Negeri Batam, 2017-12-22) Novian, Taufik Ramadhan; Wijanarko, Heru; Wivanius, Nadrah
    Locker is place of storage that important for user, but locker always get some problems when using it such as key easily lost or left behind because the key have small size and easily to duplicated. It is the background of the problems to create ”The system of security locker using GSM module, Bluetooh Module and Reed Sensor”. The purpose of this project is to replace manual key to be smartphone for access the locker because manual key sometime easy lose or left behind. This research was conducted to understand the problems that occur directly and making habits in using a smartphone into a solution. The habit is always to bring smartphone anywhere so the possibility of missing or left behind is very rare. In order to use smartphone as a key, smartphone act as a transmitter which smartphone just send a message or activates bluetooth in order to unlock or lock the locker. The results of using smartphone as a electronic key for locker system is more flexible because user can access the locker anywhere and more effective because the key always bring anywhere and can not be duplicated without the permission of the user as a safety factor.

    Trainer Penyearah Terkendali Satu Fasa
    (Politeknik Negeri Batam, 2017-02-24) Oktoriansyah, Faizal; Hasnira, Hasnira; Gozali, M Syafei
    The rectifier is an electronic circuit that converts alternating current into direct current. There are some circuit or component that will be used for example triac, SCR or diode. Therefore, the creation of this controlled rectifier trainer is needed to perform student pratikum and to save time in doing pratikum. Making this rectifier trainer aims to avoid or reduce usage by using projectboard and also can be as safety, and can minimize the existence of damage to component when arranging a series. When making the trainer, there is a method of making controlled rectifier circuit, one of which is the authors choose by using PWM method that can trigger the foot gate on SCR, PWM method in use that is using Arduino. Arduino can produce output that can be set with the program. By adjusting the angle of ignition will be easier to get the desired waveform, so that students who will perform pratikum will set the angle of ignition that has been specified.
