Abstract

Hysteresis is widely applied in converter control techniques because of its simplicity and stability. This paper discusses hysteresis current control applied to single-phase active filters. Active filters are designed for harmonic mitigation and reactive power compensation. Simulation and comparison of conventional hysteresis control (constant hysteresis band - variable frequency) and adaptive hysteresis (variable hysteresis band - constant frequency) on active filters were carried out. Simulations were carried out using MATLAB Simulink. The simulation results show that the active filter can work well when using conventional or adaptive hysteresis current control. This is indicated by a decrease in the THDI of the source current and an increase in the power factor on the source side. From the simulations carried out, with a maximum source current THDI target of 5% according to the IEEE 519 standard, the hysteresis band required for conventional hysteresis control is 0.5 A, and the switching frequency required for adaptive hysteresis control is 120 kHz. By increasing the power factor to unity, it results in a reduction in reactive losses in the system. These findings are significant in advancing more efficient power quality control strategies, reducing harmonic distortion and improving power factor in electrical systems. Such improvements contribute directly to the development of more sustainable and resilient electrical infrastructures.

Abstract

The rapid adoption of Internet of Things (IoT) technologies by startups has intensified concerns related to data governance, privacy protection, and information security risks. This study investigates the effect of IoT data governance quality and data privacy policy on information security risk mitigation and customer trust in IoT-based startups in Bandung, Indonesia. Using a quantitative research approach, data were collected from 150 users of IoT-based startup services through a structured questionnaire measured on a Likert scale. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS 3). The results indicate that IoT data governance quality has a significant positive effect on information security risk mitigation. In addition, data privacy policy and information security risk mitigation both have significant positive effects on customer trust. Furthermore, information security risk mitigation partially mediates the relationship between IoT data governance quality and customer trust. These findings highlight the importance of strengthening data governance frameworks and implementing transparent privacy policies to reduce security risks and enhance customer trust. This study contributes to the growing body of literature on IoT governance and provides practical insights for startup managers and policymakers in fostering secure and trustworthy IoT-based business environments.

Abstract

Pengisian daya baterai aki basah langsung dari panel surya dapat menyebabkan ketidaksesuaian tegangan dan arus akibat fluktuasi radiasi matahari, yang berpotensi mempercepat kerusakan baterai. Untuk mengatasi hal ini, dirancang dan diimplementasikan sistem pengendali pengisian baterai berbasis Arduino yang dilengkapi dengan buck converter untuk menyesuaikan tegangan dan sensor INA219 untuk pemantauan real-time. Pengujian menunjukkan bahwa sistem ini mampu menyesuaikan tegangan dan arus pengisian sesuai kebutuhan baterai aki basah 12V 80Ah, meningkatkan efisiensi pengisian, dan mengurangi risiko overcharging. Pada kondisi cerah dengan radiasi matahari di atas 500 W/m², sistem mencatat arus hingga 2049,50 mA pada pukul 08.00 tanggal 11 November 2024, sedangkan pada kondisi mendung dengan radiasi di bawah 100 W/m², arus turun hingga di bawah 300 mA. Implementasi solar tracker meningkatkan efisiensi pengisian dengan memungkinkan arus maksimum dicapai lebih awal, yakni 2049,50 mA pada pukul 08.00. Selain itu, penggunaan pembersih panel surya meningkatkan arus dari 330 mA pada kondisi kotor menjadi 570 mA pada kondisi bersih, dengan peningkatan hingga 72,72%. Hasil menunjukkan bahwa integrasi solar tracker dan pembersih panel surya meningkatkan performa sistem pengisian baterai secara signifikan. Sistem berbasis mikrokontroler ini memastikan pengendalian yang presisi, pemantauan real-time, dan proteksi otomatis, menjadikannya solusi efisien dalam pemanfaatan energi terbarukan.
