Abstract

Automotive charging system provide vehicle’s electricity consumption and battery charging. Common regulator has unstable voltage output. This research is aimed to compare the performance of common and electronic regulator. Electronic regulator designed with an AVR ATMega8 microcontroller and 16 x 2 matrix LCD. The devices are tested in the charging system of Toyota Kijang 5K automotive engine by measuring alternator voltage output using voltmeter. The engine is running at 1000, 1500, 2000, 2500 and 3000 rpm. The measurements are taken three times for 300 seconds with 30 second interval. The result shows that the average voltage output of electronic regulator increase faster at 0 until 30 second measurement period. The result also shows that electronic regulator has more stable voltage output which is 14,45 Volt. The overall comparison study shows that electronic regulator has better performance than common regulator.

Abstract

This study presents a systematic review and bibliometric analysis of Green Entrepreneurship Orientation (GEO) in micro, small, and medium enterprises (MSMEs) for the period 2018–2025. The analysis employs a combined protocol with bibliometric techniques to identify research trends, author collaboration patterns, and thematic focuses. Findings indicate that key drivers of GEO in MSMEs include environmental awareness, innovation capacity, and stakeholder pressure, while under-explored areas include green technology adoption, policy support, and sustainable supply chain integration. This study proposes a future research agenda focused on digital transformation, circular economy practices, and SME resilience in a post-crisis context.
