Perkembangan pesat kemajuan teknologi komunikasi seluler dan pengurangan biaya memungkinkan untuk menggabungkan teknologi seluler ke dalam sistem mikrokontroler untuk pengontrolan peralatan listrik. Untuk dapat mengendalikan peralatan listrik seperti lampu, kipas atau ac hanya dengan menggunakan perintah suara tanpa perlu bergerak berpindah tempat untuk menyalakan atau mematikan peralatan listrik. Penelitian ini bertujuan untuk mengendalikan peralatan listrik dengan gelombang suara dengan aplikasi android Blueetooth Voice Kontroler. Suara yang kita ucapkan sesuai dengan yang sudah diprogram dalam aplikasi Arduino pada smartphone android akan menyalakan atau mematikan peralatan listrik yang kita tentukan. Berdasarkan hasil pengujian pada prototype sistem kontrol peralatan listrik, bila aplikasi android Arduino Bluetooth Voice Controller diaktifkan dan diucapkan perintah : Kipas ON / Kipas OFF, Nyalakan Lampu / Matikan Lampu, Nyalakan AC / Matikan AC peralatan listrik tersebut akan ON/OFF setelah perintah suara diberikan.The rapid development of cellular communication technology advances and cost reduction made it possible to incorporate cellular technology into microcontroller systems for controlling electrical equipment. To be able to control electrical equipment such as lights, fan or air conditioners only by using voice commands without the need to move from place to place to turn on or turn off electrical equipment. This study aims to control electrical equipment with sound waves with the Bluetooth Voice Controller android application. The sound we speak according to what has been programmed in the Arduino application on an android smartphone will turn on or turn off the electrical equipment that we specify. Based on the test results on the prototype control system for electrical equipment, when the Arduino Bluetooth Voice Controller android application is activated and the command is spoken: Fan ON / Fan OFF, Turn on Lights / Turn off Lights, Turn on AC / Turn off AC the electrical equipment will turn ON /OFF after a voice command is given.Keywords: Android; Bluetooth; Arduino Uno; electrical equipment
Gula aren diperoleh dari nira hasil sadapan pohon aren dan merupakan salah satu bahan baku dari pembuatan makanan maupun minuman. Pembuatan gula aren yang ada di Desa Tanggari Minahasa Utara Sulawesi Utara menggunakan bahan bakuair nira (saguer), akan tetapi pada proses pembuatan gula aren masih tradisional dengan menggunakan sepenuhnya tenaga manusia. Penelitian ini bertujuan untuk membuat prototype alat pengolah gula aren dengan menggunakan kontrol Programable Logic Controler (PLC) dan monitoring Human Machine Interface (HMI), dilengkapi dengan sensor thermostat sebagai alat pengukur temperatur pada saat proses pemasakan air nira dengan gas LPG dan motor wiper sebagai penggerak alat pengaduk. Hasil pengujian yang dilakukan untuk air nira 3 liter dengan suhu ± 100 0C diperoleh gula aren 750 gram. Dengan menggunakan kontrol PLC dan monitoring HMI pada alat pengolah gula aren ini diharapkan dapat meringankan tenaga pekerja dan mempercepat proses pengadukan gula aren sampai mengental sehingga pada akhirnya dapat meningkatkan efisiensi produksi.Palm sugar is obtained from the sap of palm tree tapping and is one of the raw materials for making food and drinks. The manufacture of palm sugar in the village of TanggariMinahasa Utara, North Sulawesi, uses sap (saguer) as the raw material, but the process of making palm sugar is still traditional, using full human power. This study aims to make a prototype of a palm sugar processing tool using Programable Logic Controler (PLC) control and Human Machine Interface (HMI) monitoring, equipped with a thermostat sensor as a temperature measuring device during the process of cooking sap water with LPG gas and a wiper motor as a driving force. mixer.From the results of tests carried out for 3 liters of sap water with a temperature of ± 100 0C, 750 grams of palm sugar was obtained.Using PLC control and HMI monitoring on the palm sugar processing equipment is expected to relieve labor and speed up the process of stirring the palm sugar until it thickens so that in the end it can increase production efficiency.
