Abstract

Finding the best thickness combination of the active layer and the interlayer of organic solar cells is essential to optimizing and producing an efficient device. In this research, the thickness combination was graphed by two scan steps, i.e., the major scan (50 nm - interval) followed by the minor scan (10 nm - interval). The solar cell device was modeled by optical and 1D drift-diffusion modeling in the gvdm simulation software with P3HT: PCBM as the active layer and three different materials for the hole-selective layer (interlayer). The best power conversion efficiencies were 5.21, 4.14, and 5.22% when PEDOT: PSS, V2O5, and Spiro-OMeTAD were interlayer materials. The effective thickness for every interlayer material is 10 nm, while the effective thickness of the active layer is 220 nm (for PEDOT: PSS and Spiro-OMeTAD devices) and 230 nm (for V2O5 device). As a result, each device gives higher power conversion efficiency than that from the original setting of the software. Furthermore, this study's highest power conversion efficiency was higher than previously reported. These results suggest that scanning a more extensive range of layer thickness combinations is necessary to find the highest power conversion efficiency possible for every organic solar cell device

Abstract

Electrical power is an important parameter to determine how much electrical energy is consumed or produced. Some systems that consume or generate electricity are located in remote or difficult-to-reach locations, for example monitoring volcanoes or micro-hydro power plants at the mountains. Therefore, we need a tool to monitor the electric power from afar. In this research a tool has been designed that can monitor electrical energy with the PZEM004T-10A sensor in real time using the LoRaWAN network on the Antares platform. From the results of system testing, it can be concluded that the designed system can run well according to its function. The results of the average percentage error reading of the PZEM004T sensor against the power meter measuring instrument show a very good value where the average error obtained in the voltage parameter is 0.45%, while the error value obtained for the current parameter is 0.22%, power is 1.44% and power factor of 0.15%. The performance of the Quality of Service delay value on the network according to the standard criteria issued by TIPHON, the delay value produced by SF7 and SF10 is categorized as a bad delay. Then the delay on SF9 and SF12 is included in the good category, and the delay produced by SF8 and SF11 is categorized as a very good delay. Meanwhile, the packet loss value is included in the very good criteria for SF8-SF12 and good for SF 7.

Abstract

Batteries in electric vehicles, especially scooters, are very important to monitor to avoid the danger of overheating or to maintain battery life. In order for an electric scooter to run, a source of electrical energy is stored in a battery that is flexible and efficient. Batteries have the property of converting chemical energy into electrical energy, so it is necessary to carefully monitor their capacity. This can be done by monitoring several important parameters, namely: voltage, current, temperature on an electric bicycle. On electric scooters, it is necessary to take regular battery indicator readings. In this research, temperature sensor and voltage sensor are connected to Arduino. Arduino then sends data from the two sensors to the Blynk application via an internet connection. Users can access this data from the Blynk application on their smartphone and monitor battery performance on the electric scooter. Data sent from Arduino to the Blynk application can be used to monitor battery conditions on electric scooters in real-time and assist users in making decisions regarding the use of electric scooters. Through the test results obtained an average value of power on the battery of 71,46 W at a speed of 10 km/hour, at a speed of 20 km/hour the average value obtained was 79,34 W, and at a speed of 30 km/hour the average value the average power obtained is 87,62 W. So, the higher the vehicle speed, the higher the required battery performance.

Abstract

Abstrak Pembangkit listrik tenaga angin merupakan sumber energi yang potensial untuk menghasilkan listrik secara berkelanjutan dan ramah lingkungan. Proses pemantauan dan pengukuran parameter listrik yang dihasilkan umumnya dilakukan dengan cara manual menggunakan sebuah multimeter analog ataupun digital dan dilakukan pada lokasi alat tersebut berada. Sehingga dirasa kurang efisien karena membutuhkan waktu yang cukup lama serta data tidak dapat diperoleh setiap saat. Dalam penelitian ini, penulis merancang sebuah monitoring prototype pembangkit listrik tenaga angin mini berbasis Internet of Things yang dirancang untuk memantau dan mengumpulkan data dari ptototype pembangkit listrik tenaga angin mini secara real-time. Prototype ini terdiri dari turbin angin, generator, sensor INA 219, dan sensor tegangan DC yang terhubung ke NodeMCU ESP32 sebagai perangkat utama pengolah data. Sensor tersebut digunakan untuk mengukur parameter arus dan tegangan. Data yang dikumpulkan oleh modul sensor dikirim ke platform thingspeak melalui jaringan Wi-Fi dan ditampilkan pada LCD. Sistem monitoring pembangkit listrik tenaga angin mini berbasis IoT dapat bekerja dengan baik, melalui hasil monitoring didapatkan nilai rata-rata daya pada PLTB mini dengan kecepatan angin 4 knot diperoleh sebesar 0.00640913 Watt/s, pada kecepatan angin 5,6 knot diperoleh daya sebesar 0.00758126 Watt/s. Sehingga semakin cepat kecepatan angin maka semakin tinggi daya yang akan dihasilkan. Kata kunci: Internet of Things, Sensor INA 219, Sensor Tegangan, NodeMCU ESP32, ThingSpeak.
