    Mesin Penyemprot Hama Tanaman
    (Politeknik Negeri Batam, 2017-02-27) Vandmme Simangunsong, Nico; Arifin, Muhammad
    To reduce the heavy work of farmers , then a machine Sprayers Plant Pest can be used to ease the work of farmers and can reduce work of farmer in the fields. The device will work as you want if the rotary switch is rotated. There is 3 condition is serve in this device, mean Low, Medium, High. Voltage when low condition is 7 volt, and voltage when medium condition is 9 volt and voltage when high condition is 11 volt.

    Trainer Penyearah Setengah Gelombang dan Gelombang Penuh Tak Terkendali Tiga Fasa
    (Politeknik Negeri Batam, 2016-12-28) Forza Azzuarra, Enrieco; Gozali, M. Syafei
    In principle, the half wave rectifiers and full wave rectifiers of three phase consist of a single phase transformer connected wye on the primary and secondary sides, diodes, and capacitors. This circuit serves to convert alternating voltage (AC) into direct voltage (DC). In this Last Project, the rectifier trainer made uncontrolled half wave and three phase full wave. The input voltage source used in this trainer is a three-phase voltage of 380 V, which is then downgraded to 20.7 V using a transformer. The measured load results from half wave and full wave rectifiers produce different output voltages, as for the full wave at load R is 19.848 V, at load L is 14.886 V, and at load C is 13.232 V. While at half-wave load R produce output voltage equal to 8,632 V, at load L yield 8,881 V, and at load C equal to 5,419 V.

    Trainer R-L-C
    (Politeknik Negeri Batam, 2017-02-24) Bagus Saifullah, Achmad; Arifin, Muhammad
    Learning achievement of the students affected various factors that influence these factors one of which is of many kinds of learning. Instructional media used when prises learning. A media that can help learning about electronics components, namely resistor, inductor, and capasitor. A media call name is Trainer R-L-C. Making this Trainer R- L-C need ingredients like box size 30x40, banana socket, pcb board, and some components of electro like (resistor, capasitor, diode, lowering the voltage regulator, and IC NE555). From observations made on experiemental tool RLC NE555, it can be conclude that the greater the voltage in use, the greater the frequency generated. Calculations produced by the oscilloscope is not much different from the manual calculation, but more precise and easier if you use an osilloscope.
