The tool in this study can control, measure the water level and water temperature in the open evaporation pan automatically. Water level measurements were carried out using the HC-SR04 sensor and water temperature measurements using the DS18B20 sensor. The method used is the Internet of Things (IoT) in order to send data from a NodeMCU type microcontroller as sensor processing and display data on water height, water temperature and control systems stored in databases and websites. The Internet of Things (IoT) can help transmit data remotely to monitor observations of open evaporation pans. The results of the sensor data can be seen through a 20x4 LCD and a website that displays sensor data and the status of the control system on the water pump and solenoid valve. The HC-SR04 sensor can work when the reading is directly into the water without an object. The results obtained are less accurate because the accuracy value on the HC-SR04 sensor is 3mm, while the measuring instrument from BMKG with an accuracy of 0.05mm requires a tool. From the results of the data in this research tool has an average error of 4mm. On the DS18B20 sensor, the resulting value gets an average difference of 0.8 degrees. The water level control system at specified hours with specified conditions works well. Water level data, water temperature can be displayed on the LCD and can be sent via the website once every 1 hour for 24 hours.Alat pada penelitian ini dapat mengontrol, mengukur ketinggian air dan suhu air pada panci penguapan terbuka secara otomatis.

Abstrak— Energi listrik tergolong sebagai kebutuhan primer yang diperlukan manusia. Berbagai kebutuhan manusia memerlukan mobilitas yang tinggi seperti contohnya kendaraan listrik atau peralatan listrik yang lainnya. Kabel yang terlalu banyak digunakan dapat membatasi mobilitas perangkat. Oleh karena itu diperlukan solusi agar mobilitas pada perangkat listrik dapat bekerja dengan baik. Salah satu contoh aplikasi Wireless Power Transfer adalah proses pengisian daya nirkabel. Perangkat Wireless Power Transfer perlu diketahui karakteristiknya guna menghasilkan keluaran yang sesuai agar dapat digunakan pada aplikasinya. Metode yang digunakan dalam penelitian ini adalah eksperimen. Eksperimen dilakukan dengan memberi perubahan posisi dan media penghalang diantara kumparan transmitter dan kumparan receiver. Variasi posisi dilakukan memberikan jarak,sudut,dan pergeseran pada kumparan. Variasi media penghalang digunakan menggunakan bahan isolator dan konduktor. Semakin dekat jarak antara transmitter dan receiver semakin besar tegangan listrik yang dihasilkan oleh wireless power transfer. Posisi sudut pada transmitter dan receiver mempengaruhi tegangan keluaran yang dihasilkan. Semakin dekat posisi sudut antara transmitter dan receiver menghasilkan luas bidang medan magnet yang semakin besar sehingga menghasilkan tegangan receiver yang besar. Pergeseran yang terjadi pada receiver yang semakin besar menghasilkan tegangan receiver yang semakin kecil pada perangkat wireless power transfer. Media penghalang bahan isolator tidak mempengaruhi tegangan receiver yang dihasilkan sedangkan media penghalang berupa konduktor akan mempengaruhi tegangan receiver yang dihasilkan.

Electricity is a vital need and economic resource that is needed for all communities. One of the electricity technologies that can be generated from water is utilizing water discharge to be converted into electrical energy or called PLTMH (Microhydro Power Plant). This research has been done but still needs to be developed, for example on an automatic loading system. With the help of a 1 channel relay to control the dummy load automatically. This research uses 2 different test simulations and different wiring circuits. The results of this study show that in simulation 2 the dummy load system cannot run at all. Due to the voltage value read is not so stable by the ZMPT101B sensor. The spike of the read voltage value causes it to be difficult for the relay to analyze the voltage value then causes the logic on the relay to be disturbed and an error occurs in the automatic dummy load system. However, in simulation 1 the dummy load system can work properly. For comparison of voltage values between a multimeter with a voltage value of 4.5 V (before adding a load) and on the Arduino IDE with an average of 4.564 V, the average error is -1.42222. For comparison of frequency values between multimeter 47 Hz without load and on Arduino IDE with an average value of 47 Hz with an average error of -0.8, from ac generator rotation with a voltage value of 4.5V.
