Listrik merupakan salah satu kebutuhan primer untuk kehidupan manusia sehingga diperlukan suatu pembangkit tenaga listrik. Pembuatan pembangkit listrik tenaga mikrohidro ini bertujuan untuk mengetahui daya keluaran yang mampu dihasilkan oleh flywheel magnet sepeda motor yang dilakukan pengujian di Waduk Botok, Mojodoyong, Kedawung, Sragen, Jawa Tengah dan sekaligus memanfaatan energi terbarukan secara optimal terutama air. Pemanfaatan aliran sungai di Waduk Botok untuk Pembangkit Listrik Tenaga Mikrohidro ini menggunakan kincir air tipe overshot. Desain kincir air dibuat sedemikian rupa agar dapat memutar flywheel magnet secara maksimal, karena kincir air digunakan sebagai penggerak awal. Sistem pembangkit ini memanfaatkan flywheel magnet sepeda motor sebagai pembangkit listrik, kemudian diubah menggunakai inverter, sehingga menghasilkan keluaran tegangan AC. Daya yang dihasilkan flywheel magnet dengan debit air sebesar 0,017016 (m3/s) dengan kecepatan air 3 m/s mampu memutar flywheel magnet asli dan flywheel magnet modifikasi dengan kecepatan putar flywheel magnet rata-rata 750 rpm. Daya DC yang dihasilkan flywheel magnet saat dipasang beban lampu maksimal 22 watt flywheel magnet asli menghasilkan daya DC sebesar 12,8 watt dan flywheel magnet modifikasi sebesar 12,4 watt, sedangkan daya AC yang dihasilkan flywheel magnet saat dipasang beban lampu maksimal 22 watt flywheel magnet asli mampu menghasilkan daya AC sebesar 11,3 watt dan flywheel magnet modifikasi sebesar 11,9 watt.

Currently various outdoor activities are carried out by the community. These activities are sometimes carried out for several days. To support these activities, emergency power sources are needed to recharge the batteries for lighting, communication equipment and other electronic equipment. Emergency power sources used by many people are powerbank with a limited capacity. If the outdoor activities are carried out for several days, the powerbank will not be sufficient to meet the needs. Therefore, a small scale power plant is needed by utilizing the existing natural resources such as water flow or wind. This research aims to design and to make a prototype of a nanohydro power plant that can be used to meet electrical energy needs during outdoor activities. The research begins with designing a nanohydro power plant system includes a water turbine, mini generator, and battery charger. After that, the generator prototype was made. The prototype was tested in the laboratory and on the river. Tests are carried out in no-load and loaded conditions. In each test, a voltage measurement is carried out on the generating system. The laboratory test results show that the mini generator can generate voltage from 0.57 - 6.40 V when rotated at speeds of 150 - 3000 rpm. When tested in a river with water velocity varying from 0.25 to 0.45 m/s, the generator can generate a voltage of 1.9 - 3.1 V.

Motor listrik yang banyak digunakan dalam industri adalah jenis motor induksi. Motor induksi dibedakan berdasarkan sumber listrik PLN yaitu 1 fasa, dan 3 fasa. Motor induksi 3 fasa merupakan motor yang banyak digunakan, namun memiliki kekurangan salah satunya yaitu sulitnya untuk mengatur kecepatan dari motor induksi 3 fasa. Kekurangan tersebut dapat diatasi dengan sistem pengendali inverter atau Variable Frequency Drive (VFD), Human Machine Interface (HMI), Programmable Logic Controller (PLC) yang ditambahkan dengan expansion PLC. HMI berfungsi untuk melakukan input frekuensi 0-50 Hz, kemudian akan diproses oleh expansion PLC dan menghasilkan skala 0-10 VDC yang dapat diterima oleh VFD. Masukan nilai dari VFD akan dikonversikan menjadi nilai frekuensi 0-50 Hz untuk menggerakkan motor. Berdasarkan hasil penelitian nilai kecepatan motor yang dibaca oleh sensor infrared dan tachometer mengalami kenaikan saat nilai frekuensi dinaikan, namun dari nilai rpm tersebut terdapat selisih hasil pembacaan kemudian dibandingkan antara kedua data tersebut dan mendapatkan rata-rata error 6,9%. Nilai tegangan berbanding lurus dengan kenaikan frekuensi motor induksi 3 fasa.

Sawah di Desa Wonorejo merupakan sawah tadah hujan dimana petani mengandalkan air hujan untuk bercocok tanam. Untuk mengatasi masalah ini, beberapa petani mengebor sumur di ladang mereka, dan menggunakan pompa submersible untuk mengangkat air ke sawah. Sebelum kegiatan pengabdian masyarakat ini, pengoperasian pompa submersible dikontrol secara manual. Cara pengoperasian ini memiliki kelemahan dimana sering terjadi pengairan yang berlebihan yang dapat merusak komoditas pertanian, pemborosan tenaga, dan pemborosan waktu. Pengabdian masyarakat ini menawarkan solusi dengan menyediakan perangkat pensaklaran semi otomatis yang akan membantu mengatasi masalah tersebut. Perangkat yang terpasang menggantikan alat switching manual sederhana, di mana beberapa sudah dalam kondisi keamanan yang kurang. Perangkat ini dilengkapi dengan timer yang dapat digunakan untuk mengontrol pompa secara otomatis sesuai keinginan, komponen proteksi beban lebih, dan dilengkapi dengan lampu indikator yang menunjukkan tiga kondisi yaitu pompa hidup, pompa mati, dan terjadinya gangguan pada operasi pompa. Evaluasi pada evaluasi kegiatan pengabdian masyarakat ini menunjukkan semua mitra yang terlibat dalam kegiatan ini, mengapresiasi kegiatan ini, dan ingin dilanjutkan di masa yang akan datang.

Rice fields in Wonorejo Village are rainfed rice fields where farmers rely on rainwater to grow crops. To solve this problem, some farmers drill well on their farms, and use submersible water pumps to lift up water to distributed to the rice fields. Prior to this community service activity, the operation of the submersible pump was manually controlled. This operation method had a drawback where excessive irrigation often occurred that could result on damage agricultural commodities, energy waste, and inefficient working time. This community service offers a solution by providing semi-automatic switching devices that will help to overcome this problem. The installed devices replace simple manual switching tools, in which some are in already less safety condition. The device is equipped with a timer that can be used to control the pump automatically as desired, an overload protection component, and equipped with indicator lights that indicate three conditions: the pump is on, the pump is off, and the occurrence of disturbances in pump operation. Evaluation on this community service activities evaluation shows all partners involved in this activity, appreciate this activity, and wanted to be continued in the future.

This research aims to assist farmers in controlling plant pests, birds and insect, by applying an appropriate electronic technology. The system operates in an automatic and remote-controlled modes using IoT technology. We used a solar powered systems that are environmentally friendly with zero carbon emissions, as an energy source for the systems. The test results showed that the bird pest control system worked well according to the automatic and remote-control modes design. We compare those two methods to evaluate the most effective between those two methods. Bird pest control using two actuators, sound and movement, outsmart control using only sound by success ratio 70:50. The insect pest control system worked well with the remote-control mode through Telegram application on farmers’ smartphones.

DC motors are widely used as propulsions, including in electric bicycles. The problem faced by students in the DC motor control laboratory working using software simulation is that they do not have practical learning experience using digital instruments. This article aims to develop a DC motor speed control that can be used to learn practical Proportional Integral Derivative (PID) control in the laboratory. The DC motor speed control was developed using a combination of Arduino UNO microcontroller and Matlab software. The PID method was used because it is still broadly studied and applied in industries. The test results showed that the developed trainer can work well with PID variable values that can be entered via the keypad, and DC motor transient responses can be displayed in Matlab. From the experimental results, it was found that the optimal PID variable values were Kp=0.04, Ki=0.05, and Kd=0.004, where the controller produced a low overshoot value, i.e., 0.73% of its set point and a settling time of 10.66 seconds. The test results of using the developed trainer in the Fundamental of Control Engineering laboratory work showed that the developed trainer gave students practical learning experience in designing PID control for DC motor speed by using digital equipment, i.e., microcontroller and actual DC motor as well as analyzing its corresponding transient response in Matlab software environment
