Alat ukur kilo Watt Hours (kWh) meter yang terpasang di setiap rumah pelanggan PLN baru sebatas memberikan data pemakaian energi listrik dalam satuan KWh saja, sedangkan biaya tarif listrik belum dapat ditampilkan. Selain itu juga data pemakaian listrik tidak dapat dilihat dari jarak jauh. Seiring perkembangan teknologi yang semakin pesat terutama dibidang Internet of Things (IoT), maka diusulkan sistem monitoring pemakaian energi listrik dari jarak jauh secara realtime dengan mengunakan antarmuka Blynk pada smartphone. Sistem monitoring dirancang untuk dua kelompok beban dengan menggunakan ISP32 sebagai pengolah data yang diterima dari sensor PZEM-004T dan dikirim langsung ke server Blynk sehingga data dapat di akses atau di monitoring pada smartphone melalui aplikasi Blynk. Data yang ditampilkan pada aplikasi Blynk berupa daya (Watt), tegangan (Volt), arus (Ampere), frekuensi (Hz), energi listrik (KWh), dan tarif pemakaian listrik dalam rupiah secara realtime. Berdasarkan pengujian yang telah dilakukan dapat disimpulkan bahwa alat monitoring pemakaian energi listrik telah bekerja dengan baik, dimana alat ini telah mampu memberikan data-data pemakain listrik dari jauh secara realtime.

Clean water is one of the most vital needs for a mosque. Clean water is generally taken from wells using electric water pumps. The use of water pumps is often a problem in areas where the electricity network is often off, as happened in the Raya Mosque of Nagari Salareh Aia, Palembayan District, Agam Regency. To overcome this problem, a solar automatic water pump is designed which is equipped with a battery as a backup power supply and one phase inverter to convert the solar panel voltage to alternating voltage according to the voltage of the water pump motor. The water pump automation is designed using a floating switch installed in a water tank. This solar water pump is implemented using a 300 wp solar panel, a 90 Ah battery and a 1200 Watt inverter. This solar water pump is also equipped with a solar charger for charging and discharging batteries. Field test results show that the automatic solar water pump proposed in this service program has been working properly according to the plan.

Wind turbines function as producers of mechanical power to drive generators in wind power plants. One factor that needs to be considered in the operation of wind turbines is the maximum capacity of the generator. Wind turbines must operate below the generator rating so as not to cause damage to the generator. Therefore, the operation of the wind turbine needs to be monitored and controlled to keep it operating within the generator rating limits. In this paper a horizontal axis wind turbine monitoring sistem is proposed using an Android smartphone. Wind turbine monitoring includes wind speed and turbine rotation speed parameters. This parameter data is obtained from sensors that are processed with Arduino Mega 2560. Data from Arduino is sent via the Bluetooth HC-04 module to be displayed on an Android smartphone. The experimental results show that the proposed wind turbine monitoring system has worked well. This can be seen from the wind speed and turbine rotation data that is displayed on android is exactly the same as the data on the measuring instrument

Energi listrik yang dihasilkan dari sebuah pembangkit akan disalurkan pada sebuah subsistem yang dinamakan dengan single machine infinite bus, tetapi gangguan pada sistem single machine infinite bus seperti perubahan beban secara acak pada sisi pembangkit dapat mengakitbatkan kestabilan sistem berubah sehingga sistem single machine infinite bus tidak berjalan normal. Artikel ini bertujuan untuk menganalisis kestabilan dinamik pada sistem single machine infinite bus menggunakan kontrol power system stabilizer dan kontrol propotional integral derivative. Metode kepustakaan diterapkan untuk menganalisis data dan parameter single machine infinite bus yang disimulasikan menggunakan software matlab v. R2020a. Hasil analisis kestabilan dinamik sistem single machine infinite bus pada perubahan sudut rotor secara keseluruhan setelah memberikan gangguan dinamik sebesar 0.013 p.u dengan menambahkan PSS dapat meredam 0.068 osilasi pada sudut rotor yaitu ketika sudut rotor berada pada titik 0.359 p.u menjadi 0.291 p.u dan pengurangan waktu yang singnifikan juga terjadi pada sistem ini sebesar 7.3 detik serta meredam overshoot dari nilai 38.19% menjadi 2.57% serta dapat meredam 0.000115 osilasi pada frekuensi yaitu ketika frekuensi berada pada titik 0.000329 p.u menjadi 0.000214 p.u dan pengurangan waktu yang singnifikan juga terjadi pada sistem ini sebesar 4.2 detik serta meredam overshoot dari nilai 55.58% menjadi 0.57%. Penambahan kontrol propotional integral derivative pada sistem single machine infinite bus yang dilengkapi power system stabilizer memberikan hasil yang sangat baik dalam meredam osilasi sudut rotor dan frekuensi yang dilihat dari hasil pengukuran dapat meredam 0.073 p.u pada sudut rotor dan 0.000176 pada perubahan frekuensi dan meredam overshoot dari 55.58% menjadi 0.50%.

Solar power plants are a type of electricity generation from renewable energy sources that are widely developed in Indonesia. The power produced by solar power plants is determined by the temperature and radiation from the sun hitting the surface of the solar panels. The greater the solar radiation on the solar panels, the greater the power produced by the solar panels. The maximum radiation of sunlight can be obtained if the surface of the solar panels is perpendicular to the position of the sun. Therefore, the surface of the solar panel needs to be controlled to match the position of the sun which is always moving. This paper proposes time-based tracking of the sun's position without sensors. Solar tracking system (solar tracker) is implemented with Arduino and Real Time Clock (RTC) DS 3231 as a timer. The test results show that the proposed solar tracker has worked well, where the position of the solar panels can follow the movement of the sun

Motorcycle pedicab is one of the land transportation vehicles that are still widely used by the community, especially for short distances. One of the disadvantages of using a motorcycle pedicab for transportation is the unavailability of standard fare for passengers. In this paper, a taximeter is proposed to determine motorcycle pedicab rates based on distance traveled. The taximeter display in the form of mileage and rate is designed using the Android application and Arduino Uno as data processing. This device is equipped with a hall effect sensor as a reader of wheel rotation and a bluetooth module as the interface between Android and Arduino. In addition, the Android screen also provides a start and stop button to start or stop the calculation of the meter. The experimental results show that this devices have worked in accordance with the objectives, where the android screen has been able to display distance data and pedicab rates according to mileage.
