Journal of Electrical Engineering, Energy, and Information Technology (J3EIT) (E-ISSN: 3026-1856) is the latest name for the JTE UNTAN, which underwent a name change. This journal has been in circulation within UNTAN since 2013 under its previous name. The name change reflects an evolution in the topics covered by the journal, encompassing the fields of electrical engineering, energy, and information technology. With the establishment of J3EIT, it is expected to become a significant resource for the academic and research community in this discipline, fostering the exchange of knowledge and innovation among professionals in the field of electrical engineering and related areas. By consistently publishing high-quality scientific papers, this journal is expected to play a vital role in advancing knowledge in its field. J3EIT is published three times a year, April, August and December.

Abstract

This research aims to design and implement an IoT-based speaker control system for Quran Murottal using voice commands, specifically targeting visually impaired individuals. The system utilizes speech recognition technology to overcome the challenges that visually impaired users face when controlling devices through buttons or remotes. The Android application "Qirabox" integrates Google Speech Recognition to convert voice commands into text, which is then processed by the Aho-Corasick algorithm for pattern matching. The system uses the MQTT protocol for IoT communication, with an ESP32 microcontroller and an IR Transmitter to send infrared signals to control the speaker. The system was evaluated through 50 trials with 10 visually impaired participants at PERTUNI Malang, resulting in a low error rate of 2%. Furthermore, the System Usability Scale (SUS) evaluation provided a score of 78.75 (Good), indicating the system"™s usability and effectiveness in meeting user needs. This research demonstrates the potential of voice-controlled speaker systems and contributes to the development of assistive technology for visually impaired individuals, offering a significant improvement in accessibility and ease of use.

Abstract

PLTS is one of the renewable energy solutions that utilizes solar radiation as the main source of its generation, so it is considered environmentally friendly and has great potential in areas with high sunlight intensity. The research methods used include collecting solar radiation data, PLTS system design, and performance simulation and testing using HOMER Pro software. This research was conducted at the Ministry of Politics, Law and Human Rights Building in the Nusantara Capital development area in Penajam Paser Utara Regency, East Kalimantan. The tool used to help solve this research problem uses software, namely HOMER Pro. Based on the data obtained, the estimated load consumed in these 4 buildings is 4,222 kWh/day. The PLTS is planned to be built with a capacity of 550 Wp with a total of 376 units, while the inverter capacity is 15,000 Watts with 8 units and 11,000 Watts with 8 units. Based on the results of manual calculations and using HOMER Pro software, the payback period value can be obtained of around 8 to 9 years. and this PLTS will be planned to operate for 25 years.

Abstract

Matlab is a software that is capable of performing calculations and simulations as well as developing applications based on Graphical User Interface (GUI). GUI-based application development can be done for digital signal processing, one of which is IIR digital signal filtering. The purpose of this research and development is to design a GUI to simulate an IIR digital filter. By entering the signal to be filtered and providing input parameter values in the form of filter type, filter order, cutoff frequency, passband ripple, and stopband ripple, the GUI will process the input values to filter the input signal given into an output in the form of a frequency spectrum. This GUI will be made stand-alone so that users do not need to open the Matlab application to use it. Testing for IIR digital signal filtering from the GUI is carried out by a digital filter verification test by comparing using various different cutoff frequencies, while maintaining other parameters where the results of the output signal have the same characteristics according to the filter. Then, to test the usefulness of each button, a blackbox test is carried out where the results obtained are that all buttons can work according to their respective functions without any problems or errors so that the resulting GUI can be used for IIR digital signal filtering. Then, for testing the GUI display, a survey was conducted on 30 respondents where the results had a value of 4.26 with the statement very satisfied.
