Abstract

Hipotermia merupakan salah satu penyebab utama kecelakaan pada kegiatan pendakian gunung. Kondisi ini terjadi ketika suhu tubuh inti turun di bawah batas normal sehingga dapat mengancam fungsi organ vital dan berakibat fatal. Penelitian ini bertujuan merancang sabuk pintar berbasis mikrokontroler ESP32 yang dapat memantau suhu tubuh pendaki secara real-time, mendeteksi fase hipotermia, dan memberikan peringatan dini. Alat ini menggunakan sensor suhu MCP9808 untuk membaca suhu tubuh, OLED 0.96 inci sebagai penampil data, DFPlayer Mini dan speaker untuk peringatan suara, buzzer sebagai alarm tambahan, serta LED berdaya tinggi sebagai sinyal darurat dengan pola SOS. Sistem dikategorikan berdasarkan usia pengguna (remaja, dewasa, dan lansia) dengan batas suhu berbeda pada setiap fase hipotermia. Hasil pengujian menunjukkan bahwa sensor MCP9808 memiliki akurasi yang baik dengan deviasi ±0,3°C dibandingkan termometer medis. Cahaya LED dapat terlihat jelas hingga 48 meter, sedangkan bunyi buzzer terdengar hingga jarak 32 meter. Dengan demikian, sabuk pintar ini dapat berfungsi sebagai sistem peringatan dini yang efektif untuk mencegah hipotermia dalam kegiatan pendakian gunung.

Abstract

This community service activity aims to design and implement a solar panel-based Emergency Box as a learning medium and emergency power supply solution at the Raudlatul Ulum Islamic Boarding School, Kalisat, Jember. This activity was motivated by limited electrical facilities and minimal learning practice facilities within the Islamic boarding school environment. The implementation method included literature study, needs analysis, system design, tool assembly, and outreach and mentoring activities for teachers and students. The results of the activity showed that the designed Emergency Box was able to function optimally as an alternative power source for lighting and charging electronic devices. Through training and mentoring, teachers and students gained an understanding of the working principles of solar energy as well as technical skills in operating and maintaining the device. This activity is expected to improve the quality of practice-based learning and raise awareness of the importance of using renewable energy in the Islamic boarding school environment

Abstract

The need for a smart grid has been spurred by the growth of distributed generation, the aging of the current grid infrastructure, and the desire to alter networks. The development and enhancement of smart grid technology is significantly facilitated by the Internet of Things (IoT) technology. Batteries play a crucial role in the energy storage of electrical systems, including smart microgrids and electric vehicles. To enhance performance and prolong battery life, a Battery Monitoring System (BMS) is required to manage the energy storage process dynamics within the battery. Battery life prediction contributes to the consistent and efficient operation of battery-powered devices. This research presents battery charging monitoring using Nodered. Apart from that, the battery charging feature uses a cut-off concept. The cut off on the battery is to prevent the battery from over-discharging which can damage the battery and shorten its lifespan. This research carried out validation using 3 case studies on battery charging. Validation of measurements uses a comparison between the INA 219 sensor and a multimeter. From experiments, current testing from 3 case studies, it was found that the average difference in current sensor error was 0.19%.

Abstract

Electricity consumption continues to increase as electronic equipment is used, resulting in rising monthly electricity bills. The background to this title stems from an electricity consumption survey. The survey team encountered difficulties monitoring electricity usage on the electrical panels in each building. The urgency of this research is to facilitate monitoring of electricity usage on three-phase electrical panels that can be easily installed and removed for use in various electrical panels The electrical energy data is accumulated from all three phases every second to determine the total electrical energy consumption across all three phases, the ESP32 microcontroller is also used as the brain for controlling the transmission and recording data in a Google spreadsheet for data storage.The results of the electrical energy measurement test, comparing the designed device with  3-phase kWh meter over six days of testing, revealed that the error value of the designed device was 0.26%, which is the maximum error value stipulated error limit of ±1%. This indicates that the designed measuring instrument has a high level of accuracy and meets international measuring instrument standards, with an average accuracy of 99.74%. The IEC 62053-21 standard is an international reference standard that regulates the accuracy and error limits for electrical energy meters (kWh meters). These results indicate that the designed electrical energy monitoring device is capable of performing well and accurately, approaching the values ​​of standard electrical energy meters (kWh meters).

Abstract

Conventional irrigation systems in rural agricultural areas are generally operated manually and rely on fossil-fuel-based pumps, resulting in high operational costs and low efficiency, particularly during the dry season. The objective of this research is to develop an autonomous irrigation system based on an off-grid photovoltaic power system that operates automatically according to water availability conditions. The proposed system utilizes a 250 Wp photovoltaic panel, a 12 V 200 Ah VRLA battery, an Arduino Uno microcontroller, float switch sensors for water level detection, and a LoRa-based communication module for security and remote monitoring. Field testing was conducted under actual operating conditions during five hours of effective solar irradiation by measuring photovoltaic output parameters (voltage, current, power, and energy), pump operating performance, automatic control response, and LoRa communication reliability. The photovoltaic system produced a total daily energy of 622.34 Wh under the test conditions. The water pump operated for approximately 2.5 hours with an actual power consumption of ±500 W. The automatic control system successfully operated according to water availability in the river and irrigation demand in the rice field. In addition, the LoRa-based security system successfully transmitted warning signals over a distance of 300 m without data loss. These results indicate that the proposed system operates reliably for automatic rice field irrigation and remote security monitoring; however, increasing the photovoltaic capacity is recommended to better satisfy the system’s daily energy demand.

Abstract

In this article, the direct current (DC) motor control approach is presented using the sand cat swarm optimization (SCSO) method to obtain the best proportional integral derivative (PID) parameters. DC motors are popular equipment. In addition, DC motors are easy to apply. SCSO is a method that adopts the desert cat’s life in nature when searching for prey. This cat is able to detect low frequencies below 2 kHz and also has an extraordinary ability to dig for prey. This research was carried out using the MATLAB/Simulink application. To obtain the performance of the SCSO method, a comparison method was used, namely particle swarm optimization (PSO), gray wolf optimizer (GWO), whale optimization algorithm (WOA), and aquila optimizer (AO). From the results of the study, it was found that the settling time value and integral total weighted absolute value error (ITAE) value of the SCSO method were the best compared to other methods.
