    (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%.

    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.
