Abstract

Penelitian ini bertujuan untuk merancang dan menguji prototipe smart solar tracker dual axis yang terinspirasi dari gerakan bunga matahari dalam mengikuti arah matahari, dengan tujuan memaksimalkan penyerapan energi pada panel surya. Sistem smart solar tracker ini didesain agar panel dapat bergerak secara otomatis pada dua sumbu (horizontal dan vertical) sehingga orientasi panel selalu optimal terhadap posisi matahari sepanjang hari. Pengujian dilakukan dengan menggunakan mini panel surya pada rentang waktu pukul 10:00 hingga 15:00 WIB di kota Surabaya selama tujuh hari, dengan pengamatan perubahan voltase dan output charger pada kondisi cuaca yang beragam. Hasil pengujian menunjukkan bahwa sistem smart solar tracker dual axis mampu meningkatkan efisiensi penyerapan energi, ditunjukkan dengan rata-rata voltase sebesar 11,05 V dan output charger sebesar 5,10 V pada kondisi cuaca cerah. Meskipun terjadi penurunan kinerja pada kondisi cuaca berawan, sistem ini secara keseluruhan terbukti lebih efektif dibandingkan panel statis dalam mempertahankan daya keluaran yang konsisten. Rancangan yang terinspirasi dari mekanisme pergerakan bunga matahari berhasil diterapkan pada sistem tracking, sehingga panel dapat terus menyesuaikan posisinya sesuai perubahan posisi matahari. Sebagai tindak lanjut, disarankan pengembangan algoritma pelacakan yang lebih adaptif terhadap perubahan intensitas cahaya pada cuaca berawan, penggunaan sensor cahaya berpresisi tinggi, dan implementasi prototipe pada panel dengan kapasitas lebih besar untuk hasil yang lebih akurat. Melalui hasil penelitian ini, prototipe smart solar tracker dual axis berbasis gerakan bunga matahari diharapkan dapat menjadi solusi dalam optimalisasi penggunaan energi surya secara lebih efisien dan berkelanjutan.

Abstract

Penelitian ini bertujuan untuk merancang dan membangun sebuah prototipe alat pendeteksi kadar gula darah non-invasif portabel berbasis Internet of Things (IoT). Metode yang digunakan adalah photoplethysmography (PPG) dengan sensor MAX30100 pada mikrokontroler ESP32 untuk merekam fluktuasi sinyal Inframerah dan Merah dari ujung jari. Data sinyal mentah yang diperoleh kemudian diolah untuk mengekstrak fitur-fitur kunci, meliputi detak jantung (BPM), saturasi oksigen (SpO2), rasio AC/DC IR, dan rasio AC/DC Red. Fitur-fitur ini, bersama dengan data usia subjek, dianalisis menggunakan model regresi linear multivariat untuk mengestimasi kadar glukosa darah. Sistem ini dilengkapi dengan LCD untuk menampilkan hasil, serta modul SD Card dan konektivitas WiFi untuk penyimpanan data ganda ke data logger lokal dan Google Sheets. Hasil dari pengujian validasi pada 31 sampel data menunjukkan prototipe ini berhasil mencapai tingkat akurasi total sebesar 92% dengan rata-rata persentase kesalahan absolut (MAPE) sebesar 8% saat dibandingkan dengan glukometer standar. Kinerja terbaik tercatat pada mode "Setelah Makan" dan "Sewaktu", namun akurasi menurun pada mode "Puasa", terutama pada subjek di atas 40 tahun. Penelitian ini berhasil membuktikan kelayakan konsep metode estimasi glukosa berbasis fitur PPG. Disarankan untuk melakukan validasi lanjutan dengan sampel yang lebih besar dan eksplorasi model machine learning non-linear untuk meningkatkan generalisasi model.

Abstract

The background of this research departs from the challenges of globalization that cause visual homogenization and erode local cultural identity. Graphic design is a strategic medium in bridging tradition with modernity, by adapting cultural elements such as batik motifs, Javanese script typography, to cultural icons Reog and Karapan Sapi. This study aims to analyze the integration of East Java local wisdom values in contemporary graphic design through a literature study approach and descriptive qualitative analysis. The research method was carried out by reviewing 215 articles selected using the PRISMA protocol until there were 15 relevant main sources. The results of the study show that there are four main trends in graphic design based on local wisdom, namely the symbolization of performance culture and language (30%), culinary branding and local products (29%), the revitalization of cultural narratives on digital platforms (22%), and the abstraction of traditional crafts into visual assets (18%). The value of the interconnectedness between keywords shows that graphic design is now strongly integrated with interactive technology, education, and the creative economy. In conclusion, the application of East Java's local wisdom in graphic design not only strengthens the region's visual identity but also opens up opportunities for sustainable creative economy innovation.

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

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

Mobility is a major challenge faced by people with visual impairments in their daily activities. Conventional white canes commonly used still have limitations in detecting obstacles, especially those above ground level and uneven road surfaces. This study aims to develop an ESP32-based smart cane capable of detecting obstacles and road surface conditions while providing effective warnings to users. The system employs multiple ultrasonic sensors positioned at the front, left, right, and bottom of the cane. Sensor data are processed by the ESP32 microcontroller and conveyed through vibration and audio feedback. The research method includes hardware design, software development, and system testing covering sensor accuracy and response time evaluation. The test results indicate that the proposed system achieved obstacle detection with sensor error rates ranging from 0.2% to 0.6% and response times ranging from 0.7 s to 1.2 s, demonstrating reliable performance for mobility assistance. Therefore, the proposed smart cane has the potential to improve safety and independence for people with visual impairments during walking activities.

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.
