Abstract

Gardu Induk Juishin merupakan gardu induk utama yang menyuplai wilayah Kabupaten Karawang dan Kabupaten Bekasi seperti pusat pemerintahan, perkantoran maupun bisnis dan usaha. Dilihat dari beberapa konsumen prioritas diatas maka diperlukan sistem kelistrikan dan peralatan yang andal, salah satunya relai proteksi. Terjadinya kesalahan kerja (malfunction) pada relai proteksi beberapa waktu yang lalu menjadi alasan utama untuk melakukan pengujian relai.Pengujian Relai arus lebih Over Current Relay (OCR) maupun Ground Fault Relay (GFR) meliputi beberapa parameter diantaranya arus setting, pick-up, drop-off, ratio, karakteristik dan waktu kerja sesaat. Metode analisis yang digunakan pada penelitian ini yaitu diperoleh dari data pengujian dan hasil perhitungan berdasarkan data spesifikasi peralatan. Selain itu dilakukan evaluasi pada parameter hasil uji. Kemudian hasil evaluasi perhitungan dibandingkan dengan data eksisting lapangan dan standar dari KEPDIR 0520-2. K /DIR/2014 PT. PLN (Persero). Pengujian relai arus lebih pada bay tranformator-1 Gardu Induk Juishin memiliki tingkat performa yang baik berdasarkan hasil uji. Karakteristik pada relai adalah Standar Inverse (SI) dengan waktu tunda yang telah disetting OCR sebesar 0,35s dan, sedangkan pada GFR sebesar 0,67s, dengan prinsip kerja arus berbanding terbalik dengan waktu, semakin besar arus maka semakin cepat waktu relai bekerja.

Abstract

The creative economy has become an increasingly relevant topic in the context of modern business, while also growing awareness of sharia principles in the Muslim world. This article is a literature review which aims to investigate the role and influence of the creative economy in the formation of sharia creative businesses. Through data analysis from various literary sources such as scientific journals, books and articles, this study examines how the creative economy can support innovation, economic diversification and the promotion of Islamic culture in sharia creative businesses. The influence of the creative economy in sectors such as fashion, art, design and media is also analyzed in depth. The results provide insight into how the creative economy can play an important role in combining creativity, innovation and sharia principles to create ethical and competitive creative businesses in Indonesia. In this context, this literature research contributes to understanding the potential of the creative economy which can enrich sharia-based culture and economy in Indonesia.

Abstract

There are still many people who do not use special rooms for smokers or smoking rooms because the air in the room is stuffy. This research aims to overcome this problem by designing a prototype exhaust fan control system in a smoking room using an arduino uno based fuzzy method. The fuzzy logic method is used to optimize exhaust fan speed settings based on the variables of smoke content, CO gas content and the number of people detected in the smoking room. This system uses several hardware devices such as the Arduino, sensor MQ-2, sensor MQ-7, and sensor proximity. Tests were carried out to verify system performance, including the output voltage of the MQ-2 and MQ-7 sensors regarding changes in smoke levels and CO gas levels, and the distance that can be detected by the proximity sensor, as well as the accuracy of the tool output by comparing the tool output results against MATLAB. The test results of the MQ-2 and MQ-7 sensors can obtain different output voltages at each PPM level. From testing the proximity sensor, the results showed that the proximity sensor can detect objects or the human body up to a distance of 30cm. From testing fuzzy logic with MATLAB, the results of comparing the tool's output value with the MATLAB output value were obtained with an accuracy of 99.673%, which can be concluded that the tool can work well.

Abstract

Digital transformation is reshaping the Islamic banking industry through the acceleration of technology adoption, efficiency improvement, and expansion of financial inclusion. This study examines the strategies, challenges, and opportunities of digital transformation in Islamic banking using a qualitative literature-based approach. The findings show that digitalization enhances service efficiency, supports innovation, and widens access to Shariah-compliant financial services. However, issues such as limited internet infrastructure, cybersecurity risks, and insufficient digital competencies remain significant challenges. This study highlights the importance of aligning technological innovation with Shariah governance to achieve inclusive and sustainable Islamic financial development.
