    Pemotongan dan Timbangan Singkong Otomatis
    (Politeknik Negeri Batam, 2018-01-18) Ramadhan, Faiqal Aditya; Risandriya, Sumantri Kurniawan; Analia, Riska
    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.

    Pengendali Lampu Otomatis dengan Metode Fuzzy Menggunakan RFID Sebagai Identifikasi
    (Politeknik Negeri Batam, 2018-07-04) Muis, Muhamad Dahrul; Risandriya, Sumantri K.
    Lamps are a source of lighting used in homes during dark room conditions. To turn on and off the lights in homes today still use manual switches and manual operation of lights cause ineffective and efficient use. Making this research aims to create a tool for turning on and off the lights with RFID with the distance between RFID Reader and RFID Tags that can be read with an acrylic cover is 1 cm and create an automatic room lights that can adjust to the intensity of light required by the room. This tool is expected to help in the process of controlling the room lights. The method used in making this room light controller is fuzzy logic produce light intensity issued by the lamp in accordance with the desire of the customer is dim, rather dim, or bright. Based on the research that has been done, obtained results where the fastest time achieved to achieve setpoint dim for 8,1 seconds, setpoint rather dim is 28,8 seconds and setpoint bright for 4 seconds.

    Starting Up Sepeda Motor Automatic Menggunakan Remote Control dan Security System Menggunakan GSM
    (Politeknik Negeri Batam, 2017-11-03) Agustin, Belly Andre Cindi; Risandriya, Sumantri K
    Making and development of this application is motivated by the motorcycle security system that still depends on the distance, for example use the buzzer as an indicator. This system is less effective because if the buzzer continues to sound and then the battery will quickly be damaged. Making the system automatic starting up and security system using GSM is to create new innovations to make the use of motorcycles easier. This tool uses bluetooth HC-05 module and GSM sim900A module as the communication intermediary. From the results of the implementation that the automatic startup system using the remote control and security system using GSM can be operated with AT-Mega 328 microcontroller as the control center of the circuit. Work of the system starts up is when pressed the ON button then the motorcycle will turn on and when pressed the starting motorcycle will start the starter for 5 seconds, while for the security system when done manual starter GSM module will call the owner's phone number and after the motor delay will die. With this system motorcycle users more easily monitor and operate vehicle.

    Blender Jus dengan Sistem Penakar Otomatis untuk UKM Jus Buah
    (Politeknik Negeri Batam, 2018-07-06) Muhajir, Gigih; Kamarudin, Kamarudin
    A drink from fruit essence or also known as fruit juice, is a drink that loved by most of people. Nowadays, there a lot of Small and Medium Enterprises (SMEs) are involved in this industry of fruit juice making, because it’s the rapid culinary development in this batam city. Aside from the benefits of the fruit which is good for our health it’s also has a delicious and unique taste in each fruit. These days the making process of fruit juice is still in conventional way. Conventional dosing somehow using approximately of human feeling so that often inaccurate compositions are created. As a result the taste of the juice could be too sweet or even tasteless. To solve this problems, the writer created a device that could measure the composititions of each ingredients such as water, sugar, and milk using water flow sensor and solenoid valve. This device has 6 choices of portion quantities and 6 level options of sweetness which is sugarless, medium, sweet, sugarless without milk, medium without milk and sweet without milk. The given dose input will be processed by the microcontroller to control the solenoid valve and water flow sensor. The water flow sensor reads the water debit and the solenoid valve as the tap will automatically close when the desired volume is reached. The system in this blender has worked well on all portions and sweetness menus with an error percentage of 1.87%.

    Perancangan dan Implementasi Alat Pemberi Makan Ikan Otomatis Berbasis Arduino
    (Politeknik Negeri Batam, 2018-09-10) Pormes, Fredlis; Thohari, Ahmad Hamim
    Batam with nearly one and a half million residents has large needs of fish consumption. Freshwater fish farm of catfish, carp, and catfish has spread in the Batam area and the surrounding islands. Fish feed is the main cost component as well as the key of success in fish farming business.Feeding on traditional fish farming are often done manually by spreading feed from all directions. The timeliness, quantity and the technique of feeding are important things that fish farmer must be considered. We propose a design of automatic fish feeding device with scheduling that can be arranged on a web-based interface. The design and implementation pahase show that the device designed can do automatic fish feeding based the schedule and the duration specified in the web-based interface. Future development of this project is to improve the prototype so that it can be used in the fish farming environment to test the resistance to environmental factors.
