Abstract

This research aims to develop a microcontroller-based automatic liquid soap refill system integrated with the concept of a circular economy. The main problem addressed is the high use of single-use soap bottles, which negatively impacts the environment. As a solution, the designed system uses sensors to detect refill needs and perform automatic refills. A microcontroller controls this process, ensuring efficiency and user convenience. Testing was conducted to assess the system's performance under various operational and environmental conditions. The test results showed that the system functions well. Additionally, using this system reduces the use of single-use soap bottles, supports environmental sustainability, and reduces the cost of purchasing new bottles. This research concludes that microcontroller-based automation technology can be integrated with the circular economy concept to produce efficient, environmentally friendly, and economical solutions. This automatic liquid soap refill system not only enhances user convenience but also contributes positively to environmental and economic sustainability. It is hoped that the research results can serve as a reference for developing other automation technologies that support the circular economy concept.

Abstract

This research analyzes the sentiment regarding the use of electric vehicles in Indonesia through social media, utilizing over 10,000 data points from Twitter. The results indicate a variation of positive, negative, and neutral sentiments towards electric vehicles on social media. Female users play a significant role in expressing their views and actively participating in discussions related to electric vehicles. The locations with the highest user activity discussing electric vehicles are Indonesia, DKI Jakarta, Makassar, Tangerang, and Karawang. The peak activity was observed in September 2019, suggesting a significant interest in electric vehicles. The SVM algorithm achieved an accuracy of 88% for positive and neutral sentiments, but performed relatively lower for negative sentiments. This research lacks data on the gender and age of the respondents. Future studies should address these shortcomings to gain a deeper understanding of public perceptions regarding electric vehicles in Indonesia.
