Lack of student understanding of microcontroller course materials due to lack of equipment and practice modules and do not yet have a comprehensive understanding of the concept of microcontrollers. The method used in developing trainer products and modules is the Research and Development (R&D) method. The development of the first job sheet of this servo motor control practice uses manual control without recoording the position of the movement of the robot arm by using 4 (four) servo motors, resistance (potentiometer) with arduino uno microcontroller as well as constriction of the robot arm using acrylic material. Control of robot arm with servo motor control and arduino uno microcontroller can be controlled based on the input variable changes from the given resistance value, every time a resistance value changes, the rotation of the servo motor will also move according to the value given and the motor capable of working both ways (CW) and CCW). The direction and angle of movement of the servo motor rotor can be controlled by varying the pulse width (duty cycle) of the PWM signal at the control pin. The working angle of the servo motor is controlled by a pulse width of ± 20 ms, where the width of the high pulse is between 0.5 ms and 2 ms. Communication interface between the controller program application and the Arduino Uno microcontroller occurs the sending (Tx) and receiver (Rx) serial data in the form of byte data. Program development consists of three parts, namely the first part is the standard program code of the Arduino MT-100 module, the development of the robot arm program without recoording and the development of the program with recoording. So it is hoped that this module can attract students' interest in studying microcontroller courses and student interest in robotics.

Desa Taeno Bawah terletak di Daerah Rumah tiga Kecamatan Teluk Ambon dengan jumlah penduduk ±1000 Jiwa,  Situasi dan kondisi tata letak Dusun Taeno, rata-rata penduduk hidup dari bercocok tanam (petani). Cara bercocok tanam masih dilakukan secara manual (proses  penyiraman dan pemupukan), sehingga dapat berpengaruh pada hasil produksi yang mereka kerjakan. Dari cara penyiraman, untuk mengambil air masih menggunakan pikulan dan ember, sehingga kurang efisien dan waktu yang di butuhkan cukup banyak serta membutuhkan energy ekstra dalam bekerja. Dusun Taeno telah memiliki beberapa kelompok tani, masing-masing  kelompok tani terdiri dari 8 orang. Mereka menanam tanaman sayur sayuran seperti cabe rawit (Cili), Tomat, Bawang Merah, Ketimun, Terong dan Papare (Pare). Tujuan akhir dalam pengabdian ini mulai dari merancang, pemasangan, pengoperasian serta perawatan dari sistem kelistrikan jariangan distribusi, control panel, instalasi listrik ke pompa celup bagi kelompok tani taeno mekar dusun taeno. Agar proses penyiraman tanaman yang dilakukan dapat terkontrol dan terjadwal dengan baik serta dapat meningkatkan hasil produksi tanaman dan tentunya dapat meningkatkan kesejahteraan pendapatan petani.

Electricity is needed, especially for household lighting. In general, to turn off and on lights, fans, air conditioners (AC), television is still done manually by using the ON -OFF switch. Android smartphone connected to the internet and bluetooth can be used to control the microcontroller. Android smartphones are equipped with Voice command recognition feature technology or control using voice commands to control switches or other electronic devices without having to touch or direct contact with these devices, it is very helpful when compared to using a manual switch to control (ON -OFF) electronic devices, considering the current conditions where the COVID-19 pandemic period requires us to implement health protocols to reduce the spread of COVID-19. This research method is the development of research which is a load control prototype that functions as a controller that can be connected to external devices such as bluetooth HC05 and Relays, so that with the Arduino Uno or AT-Mega 328 we use it as a control for electrical devices to turn on and turn off electricity after receiving commands from Smathphone as an alternative to manual switches on those installed in residential. Testing the system with a Bluetooth signal propagation distance without obstructions and with a barrier of ± 15 meters for each load used. The temporary test is carried out by using a load of incandescent lamps with 100 watts of power as many as 4 lamps to determine how much active power consumption (pure power) is to the effect of the load used. The results of measurements of voltage, current, power, energy carried out on a 100 watt lamp load obtained a very significant value, this is due to the influence of the fluctuating PLN grid voltage ranging from 217 volts to 219 volts. Testing AMR_Voice response time to load ± 3 seconds. Testing the system with the distance of the bluetooth signal propagation without obstacles and with a barrier of ± 15 meters. Average current 0.46 A, average power 101.55 W, average energy 12.25 J. ABSTRAKListrik sangat dibutuhkan terutama untuk penerangan rumah tangga. Pada umumnya untuk mematikan dan menghidupkan lampu, kipas angin, pendingin ruangan (AC), televisi masih dilakukan secara manual dengan menggunakan saklar ON -OFF. Smartphone android terhubung dengan internet dan bluetooth dapat dimanfaatkan untuk mengendalikan mikrokontroler. smartphone android dilengkapi dengan teknologi fitur Voice command recegnation atau pengendalian menggunakan perintah suara dapat mengkontrol saklar atau perangkat elektronik lainnya tanpa harus menyentuh atau kontak langsung dengan perangkat tersebut, akan sangat membantu jika dibandingkan dengan menggunakan saklar manual untuk mengontrol ( ON -OFF ) perangkat elektronik, mengingat kondisi sekarang dimana masa pandemic COVID-19 yang mengharuskan kita untuk menerapkan protokol kesehatan untuk mengurangi penyebaran COVID-19. Metode penelitian ini pengembangan riset yang merupakan prototype pengendalian beban yang berfungsi sebagai pengendali yang dapat dihubungkan dengan perangk...
