Abstract

Sistem pengereman regeneratif telah menjadi salah satu fitur utama yang mendukung efisiensi energi pada mobil listrik. Penelitian ini bertujuan untuk menginvestigasi implementasi dan kinerja sistem pengereman regeneratif pada mobil listrik. Melalui analisis mendalam terhadap prinsip kerja, desain, dan teknologi yang terlibat, penelitian ini memberikan wawasan tentang bagaimana sistem pengereman regeneratif dapat memanfaatkan energi kinetik yang terbuang selama pengereman untuk menghasilkan energi listrik tambahan. Selain itu, penelitian ini juga menggali tantangan teknis dan potensi pengembangan masa depan dari sistem pengereman regeneratif dalam konteks mobilitas berkelanjutan. Dengan demikian, penelitian ini memberikan kontribusi penting bagi pengembangan teknologi mobil listrik yang ramah lingkungan dan efisien secara energi.

Abstract

This research focuses on the development and testing of a microprocessor-based Overcurrent Relay (OCR) with the implementation of fuzzy logic control for adaptive setting of TMS values. OCR is a crucial component in the electricity protection system which aims to detect and respond to disturbances due to excessive current, preventing damage to electrical equipment. The aim of this research is to test the feasibility and performance of microprocessor-based OCR with fuzzy logic control in setting TMS values, and compare it with the international standard IEC 60255. The method used in this research is the implementation of the Sugeno type fuzzy logic algorithm on the Atmega 328P microcontroller. This algorithm is used to control the TMS value based on the rotating frequency of the detected overcurrent. The results of this research are a characterization of the OCR response to variations in streaming current and different PS settings. The lowest TOp deviation was observed at higher PS settings, with the best performance in the IDMT OCR type. The use of fuzzy logic control is able to increase the OCR response to overcurrent disturbances, although under normal conditions it sometimes results in a longer TOp. The conclusion of this research is that microprocessor-based OCR with fuzzy logic control can provide protection performance that is adaptive and responsive to dynamic operational environmental conditions. This implementation has the potential to increase the efficiency and leakage of the electricity protection system

Abstract

The shipping system is currently less efficient in shipping speed and not environmentally friendly, so it takes a long time to receive packages and increase air pollution. In this study create a new transportation that can accelerate the delivery of goods and environmentally friendly namely that is delivery drones. The advantages of using a drone are fuel-friendly, time efficiency. In this study fuzzy methods and mapping in the control system of the drone are used. In this study produce drones that can deliver goods automatically following a predetermined path.

Abstract

This study aims to determine the effectiveness of digital marketing strategies in increasing sales in online-based MSMEs. This research approach collects data through a literature study, which involves reading literature from various sources including books, articles, journals, and reports using qualitative and deductive approaches. The results of this study indicate that digital marketing strategies are proven effective in increasing sales in online-based MSMEs. Some key strategies that can be implemented include utilizing social media as a promotional channel, optimizing marketplaces and websites, implementing content marketing, using paid digital advertising and search engine optimization (SEO), collaborating with influencers and affiliate marketing, customer relationship management (CRM), and data analysis and evaluation of digital marketing performance. The implementation of these strategies allows MSMEs to reach a wider range of consumers, build trust and loyalty, and increase sales sustainably with cost efficiency and appropriate data utilization.
