Abstract

Dewasa ini, sangat banyak jenis peralatan elektronik skala kecil rumah tangga dengan berbagai macam fungsinya. Sebagian kecil peralatan elektronik tersebut sudah mengadopsi teknologi multi tegangan input dari 100V – 240VAC. Pengaplikasian teknologi multi tegangan input digunakan karena lebih fleksibelnya power supply dari produk tersebut untuk masuk ke suatu negara baik dengan standar input tegangan AC 100V, 110V, 220V, maupun standar lainnya sesuai rentang tegangan yang tersedia. Dibalik kelebihan teknologi multi tegangan input yang tertanam pada peralatan elektronik terdapat biaya tambahan untuk rangkaian pengkondisi tegangan yang akan menambah jumlah komponen, ruang, dan biaya desain power supply pada peralatan elektronik. Pada titik ini ditemukan ketidakefisienan teknologi multi tegangan input yang tertanam pada rangkaian power supply peralatan elektronik. Oleh sebab itu, dirancang inverter yakni sebuah rangkaian pengubah tegangan listrik searah (DC) ke tegangan bolak-balik (AC) yang dapat mengadopsi multi tegangan input dari sumber tegangan DC sekaligus dapat diatur untuk rentang tegangan keluaran AC sesuai dengan kebutuhan. Secara keseluruhan sistim pada inverter diatur oleh sebuah mikrokontroler yang menjadi pusat kendali proses inverting sinyal DC. Inverter ini dirancang untuk dapat mengubah sinyal DC fluktuatif dari baterai VRLA dengan rentang 10-13VDC dan dari solar panel 50WP dengan rentang13-18VDC menjadi sinyal AC dengan rentang 80-250VAC.

Abstract

Currently, Fuel Cell technology is widely used as a supporting technology for energy storage systems in the electrical system. With the widespread use of renewable energy as an energy source today, several schemes have been tried for the installation of Fuel Cells after the converter, but the performance of the Fuel Cells is not very helpful because the response time is not significant enough to raise power requirements when input intermittent occurs (on a time scale of seconds). . In this study, a simulation of the installation of a fuel cell was carried out in an isolated electrical system (off-grid) containing solar panels. To increase the performance of the Fuel Cell, the installation will be carried out by Direct-Coupling before the converter. The results of this study indicate that the installation of Direct-Coupling can help improve the performance of Fuel Cells in off-grid renewable energy electrical systems.

Abstract

Penggunaan library OpenCV Python telah dikembangkan di segala bidang teknologi, termasuk di bidang industri. Dalam dunia industri, terdapat alat penyortir benda berupa konveyor. Alat-alat tersebut saat ini sudah lebih canggih karena menggunakan kamera untuk membaca benda-benda yang akan disortir. Tujuan dari penerapan sistem OpenCV (Open Source Computer Vision Library) pada konveyor penyortir benda ini adalah untuk mempermudah penyortiran benda berdasarkan teknologi pendeteksian warna. Metode OpenCV untuk deteksi objek berdasarkan warna digunakan untuk memilih objek-objek tersebut. Langkah pertama dalam mengidentifikasi objek yang dimaksud adalah dengan menangkap objek RGB (merah, hijau, dan biru) secara real-time dan mengubah warnanya menjadi HSV. Selain itu, dengan menutupi objek sehingga berada di tengah dan menerapkan ambang batas, proses morfologi dapat digunakan untuk menghilangkan noise yang tidak perlu dari gambar. Hasil penelitian menunjukkan kemampuan untuk membedakan objek berdasarkan warna RGB ketika mereka telah diurutkan dengan mempertimbangkan nilai HSV pada permukaan objek berwarna.

Abstract

Brushless Direct Current (BLDC) motor as an electric vehicle driving motor, its speed control is directly proportional to the voltage applied to its terminals. Therefore the applied average voltage or the average current flowing through the motor will change depending on the duty cycle of the ON and OFF time of the pulses, so the motor speed will change. The purpose of this research is to apply the ARM STM32F4 microcontroller to control the speed of the BLDC motor and obtain the transfer function equation of the BLDC motor. The method used in this study is an ARM STM32F4 microcontroller generating a duty cycle through Pulse Width Modulation (PWM) control which causes changes in the ON and OFF switches of the three-phase inverter. The variable change data is then modeled mathematically in the form of a transfer function using the System Identification Toolbox (SIT) application in Mathlab programming. The results of calculations and tests show that the ARM STM32F4 microcontroller functions well in regulating the rotational speed of the BLDC motor.

Abstract

Addressing challenges in solar panel systems, hybrid energy storage systems have gained prominence but face distribution imbalances. This study presents a power distribution approach for hybrid systems in intermittent solar scenarios, leveraging First-Order Filters to allocate power between primary and supporting storage. By employing Lowpass and Highpass First-Order Filters, energy management issues in off-grid systems are addressed. Experimental findings reveal that during high intermittency, the battery stores 387 W and contributes 62 W, while the supercapacitor stores 297 W and contributes 167 W as the primary storage. Conversely, during low intermittency, the battery stores 390 W and contributes 62 W, while the supercapacitor stores 295 W and contributes 164 W. Surprisingly, the supercapacitor doesn't outperform the battery in power efficiency as the primary storage. This work contributes to enhancing the viability of solar-powered hybrid energy storage systems by optimizing power distribution strategies. Highlight: Distribution Imbalances in Hybrid Systems: Hybrid energy storage systems for solar panels face challenges in power distribution, motivating the need for innovative solutions. First-Order Filter Allocation: This research introduces a power distribution approach utilizing First-Order Filters to effectively allocate power between primary and supporting storage in intermittent solar scenarios. Comparative Power Efficiency: Experimental results demonstrate the performance of battery and supercapacitor as primary storage, revealing unexpected power efficiency outcomes under varying solar intermittency, informing strategic energy management decisions.

Abstract

The Covid-19 pandemic that is currently spreading in Indonesia has claimed thousands of lives. Coronavirus Disease is characterized by the main clinical symptoms of fever gretar than 38 Degree C, coughing, to shortness of breath. In preventing its spread, the government conducts early detection by examining the main symptoms in the form of a fever and enforcing health protocols on each line. Therefore, we need an appropriate innovation that can make it easier for officers/guards to check human body temperature, especially in crowded places such as at airports, malls, or on the highway. Currently, body temperature measurement equipment is widely used, which allegedly made many errors in detecting it. Therefore, an innovative helmet was created that can be used by guards, security and even the police to detect body temperature based on the Arduino Pro Mini with the MLX90614-DCI sensor and the output is the real body temperature displayed on the LED screen. When the body temperature reads more than 38 Degree C, the helmet will turn on a buzzer and an LED to show that the target measurement is in a fever condition, and it is recommended going to the health center for further examination. This tool has been tested, and the sensor readings have an accuracy at a distance of 100 cm with several participants and the sensor readings are compared with the reading values from the alpha one thermometer and the measurement results have an accuracy level of 95 percent. Keywords Arduino Promini, Covid19, MLX90614-DCI, Infrared Thermometer.

Abstract

This research aims to develop a system of detecting the maturity and sorting of cavendish bananas using Open Source Computer Vision (OpenCV) and also assisted by a loadcell sensor. The problem experienced at this time is that fruit sorting is still manual which is less efficient and inaccurate in distinguishing banana maturity based on the color of the skin. This is because the human eye is sensitive to changes in lighting and fatigue. This designed system will use webcam for image processing and loadcell for fruit weight measurement, controlled by Arduino Uno microcontroller. While the algorithm used to determine the color of the ripeness of the banana fruit itself is HSV. The test results show an average weight error of 0.08% for ripe bananas, 0.71& for unripe bananas, while the color detection produces an accuracy of 47.34% on average in bright lighting conditions. In conclusion, this system is successful in improving sorting efficiency with adequate accuracy results, but further development is needed so that the accuracy level increases.
