Abstract

Saat ini, banyak perangkat elektronik yang menggunakan baterai sebagai sumber dayanya seperti handphone dan laptop. Sebuah charger baterai yang bersumber AC (Alternating Current) memiliki sebuah penyearah AC ke DC (Direct Current). Keluaran penyearah AC-DC tidak sesuai untuk pengisian CC/CV (Constant Current/Constant Voltage), sehingga diperlukan buck converter untuk menghasilkan nilai yang diinginkan. Selain itu, penyearahan AC-DC membawa ripple yang dapat merusak baterai dan mempengaruhi rectification ratio (RR), sehingga memerlukan filter untuk mengurangi ripple dan meningkatkan rectification ratio. Percobaan dilakukan pada kondisi arus konstan atau CC 1,5A dan kondisi tegangan konstan atau CV 4,2V menggunakan variasi beban. Pada percobaan CC, diketahui bahwa peningkatan beban akan menyebabkan peningkatan duty cycle yang dibutuhkan. Pada uji coba CV, diperoleh hasil bahwa peningkatan beban menyebabkan pengurangan duty cycle yang dibutuhkan. Penggunaan filter pada kondisi CC dan CV dapat mengurangi ripple dan meningkatkan RR. Pada kondisi CC, ripple matematis, simulasi, dan uji coba secara berturut-turut berkurang 46,45%, 46,43%, dan 45,46%. RR matematis, simulasi, dan uji coba secara berturut-turut meningkat 18,17%, 18,17%, dan 21,59%. Pada kondisi CV, ripple matematis, simulasi, dan uji coba secara berturut-turut berkurang 46,44%, 46,6%, dan 48,78%. RR matematis, simulasi, dan uji coba secara berturut-turut meningkat 18,17%, 18,17%, dan 20,99%. Pengisian Li-ion 3Ah memakan waktu 4 jam 58 detik. Dimana pengisian CC selama 32 menit 10 detik dan pengisian CV selama 3 jam 28 menit 48 detik. Pada pengisian CC duty cycle meningkat saat terjadinya peningkatan tegangan baterai. Sedangkan pada pengisian CV, duty cycle menurun saat berkurangnya arus pengisian.

Abstract

This research addresses the problem of temperature fluctuations affecting the efficiency of solar panels. A cooling system has been developed using a Peltier and a combination of air- and water-cooling methods. The air-cooling system involves placing a Peltier coated with a heatsink under the solar panel, while the water-cooling system uses pumped water on the panel's surface. The study aims to design a solar panel cooling system to reduce temperature and power losses and compare its output to standard solar panels. The system includes a Peltier, DC fan, and heatsink. Results indicate that the air-cooling system reduced temperature losses on the bottom milk of solar panels by 14.5%. However, the surface of solar panels showed no reduction in temperature losses. Additionally, solar panels with cooling systems were able to reduce power losses by 4% compared to standard solar panels. This research suggests that the use of an air-cooling system utilizing Peltier as the cooling medium could be a potential solution to reduce temperature losses and power losses on solar panels.

Abstract

This research endeavors to increase the lifespan of a battery utilized in a standalone microgrid system, a self-sufficient electrical system that consists of multiple generators that are not connected to the main power grid. This type of system is ideal for use in remote locations or areas where the grid connection is not possible. The sources of energy for this system include photovoltaic panels, wind turbines, diesel generators, and batteries. The state of charge (SOC) of the battery is used to determine the amount of energy stored in it. The particle swarm optimization (PSO) method is applied to minimize energy generation costs and maximize battery life. The results show that battery optimization can decrease energy generation costs from Rp 5,271,523.03 ($338.64 in USD) to Rp 13,064,979.20 ($839.30 in USD) while increasing the battery's lifespan by 0.42%, with losses of 7.22 kW and 433.29 kVAR, and also a life loss cost of Rp 5,499/$0.35.

Abstract

Muscles are an important organ in the movement of the body's skeleton to carry out sports activities. Measurement of muscle activity during the exercise process can be done using electromyography (EMG). This research uses Myoware muscle sensor (AT-04-001) which is integrated with Arduino Uno and Xbee to monitor biceps brachii muscle fatigue wirelessly. Fatigue data processing is carried out objectively using the envelope and sliding window method and subjectively verbally from the respondents. From this study, it was found that muscle fatigue can be measured using the method objectively when there is an increase in EMG amplitude with a window size of 5 s. The indication of biceps brachii muscle fatigue for the right arm is stronger to withstand the load during exercise with the average duration of the measurement of the right arm is 41.87 s from 69.67 s; 53.53 s from 98.90 s and 76.87 s from 98.80 s with the ratio of the left arm tending to fatigue more quickly is 23.53 s from 42.13 s; 41.87 s from 51.60 s and 23.53 s from 44.73 s.

Abstract

As technology continues to advance, governments around the world have implemented health protocols to minimize direct contact between individuals and objects, in response to the ongoing COVID-19 outbreak. To address this need, a touchless parking portal was designed using a microcontroller-based and internet of things (IoT) -based system, with the Arduino UNO microcontroller device serving as the core component. The system employs an ultrasonic sensor HC-SR04 and passive infrared (PIR) to detect vehicles as they arrive at the portal area, in addition to requiring an ESP32-CAM camera, servo motor, light-emitting diode (LED), I2C 16x2 liquid crystal display (LCD), push button, universal serial bus (USB) to transistor-transistor logic (TTL) converter, power supply, and portal bar. The system builder software was developed using Arduino integrated development environment (IDE), Android, and Blynk. The authors conducted thorough testing and analysis of the system, concluding that its overall performance reaches 100%. Nevertheless, despite the extensive experimentation conducted, there remains a possibility that certain factors could still affect the results. Therefore, caution is advised when interpreting the outcomes of this experiment.
