Abstract

Low power factors in industrial and household electrical systems cause energy waste, increased load flow, and financial losses due to fines for electricity providers. This systematic literature review aims to analyze the development, components, control methods, and performance achievements of microcontroller-based Automatic Power Factor Correction (APFC) systems and the Internet of Things (IoT) published in the period 2021–2026. The search was conducted through four scientific databases, namely Sage Journal, Scopus, Taylor & Francis, and IEEE Xplore, resulting in 108 initial articles that were then filtered using the PRISMA protocol until the final 10 articles were obtained. The results of the analysis show that the ESP32 and NodeMCU are the most commonly used microcontrollers, the PZEM-004T sensor as a power measuring tool, and the MQTT protocol as an efficient communication medium for real-time monitoring. The power factor improvement achieved ranges from 0.60–0.99 after the correction is applied. IoT integration has been shown to significantly improve remote monitoring and control capabilities.

Abstract

The rapid development of Artificial Intelligence (AI) has increased the use of the Gemini application to support information retrieval, task completion, and work productivity. This study aims to analyze the factors influencing the successful use of the Gemini application using the Human-Organization-Technology Fit (HOT-FIT) model. The variables examined include Service Quality, User Satisfaction, Organizational Structure, and Net Benefit. A quantitative approach with purposive sampling was employed. Data were collected from 100 respondents, consisting of students, lecturers, and employees, and analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) with SmartPLS 4. The results indicate that all constructs meet the validity and reliability requirements. The R-Square values of 0,588 for User Satisfaction and 0,676 for Net Benefit demonstrate satisfactory explanatory power. Hypothesis testing shows that Service Quality has a positive and significant effect on User Satisfaction (β=0.767; p<0.001), User Satisfaction has a positive and significant effect on Net Benefit (β=0.274; p=0.023), and Organizational Structure has a positive and significant effect on Net Benefit (β=0.599; p<0.001). These findings indicate that the HOT-FIT model effectively explains the success of the Gemini application, highlighting the importance of service quality and organizational support in maximizing its benefits.

Abstract

Ikan gurame merupakan komoditas perikanan asli Indonesia yang memiliki nilai strategis dalam meningkatkan perekonomian masyarakat, khususnya di wilayah Jember. Kendati demikian, pembudidaya masih menghadapi kendala serius berupa tingginya angka kematian pada tahap pembenihan. Fase awal ini sangat rentan dan keberhasilannya sangat dipengaruhi oleh variabel lingkungan seperti konsistensi pemberian pakan, stabilitas suhu, serta kualitas air kolam. Berdasarkan permasalahan tersebut, integrasi teknologi melalui sistem monitoring budidaya menjadi solusi inovatif yang diperlukan. Inovasi ini hadir untuk mengotomatisasi aktivitas pemberian pakan, pemantauan suhu, dan pengelolaan sirkulasi air secara mandiri. Keunggulan utama dari teknologi ini adalah kemampuannya dalam melakukan pengurasan air secara otomatis guna menjaga kebersihan lingkungan biotik ikan. Penerapan sistem ini baik dalam mempercepat laju pertumbuhan benih gurame, terutama pada rentang usia satu hingga tiga bulan, karena kualitas air yang terjaga berkorelasi langsung dengan kesehatan benih. Melalui digitalisasi ini, diharapkan efektivitas operasional pembudidaya meningkat, risiko kegagalan pada tahap awal dapat diminimalisir, dan target peningkatan pendapatan petani dapat tercapai secara berkelanjutan.
