Abstract

Café Sudut Temu by Toastea, located in Cirahayu Tegalega Street, Central Bogor, was established in 2015. The manual booking system in place at Café Sudut Temu is currently inefficient and vulnerable to error, resulting in lengthy waiting times, order errors, and challenges in inventory management. Therefore, this research is planning to build a QR code-based food ordering system through a website. The ordering system in this study was developed using the Waterfall methodology and the application was designed using the Laravel PHP framework. The design phase begins with the collection of requirements, the creation of design, the implementation or development of the system and ends with testing. This research results in a system that simplifies the ordering process, reduces errors, and improves operational efficiency.In addition, the responsive design with a mobile-friendly interface allows customers to order directly without having to wait for the help of the server. The system is expected to increase customer satisfaction and contribute to coffee growth amid increasing competition in the industry. The results of this research are a website-based application for ordering food and beverages using a QR Code on Café Sudut Temu.

Abstract

The Indonesian government is encouraging the transition to electric vehicles to reduce the use of fossil fuels and the negative environmental impact. This transition sparked controversy because Indonesia is still heavily dependent on coal-fired power plants, and many argue that the transition is not ready without adequate renewable energy and supporting infrastructure. Public opinion analysis is crucial in considering the introduction of electric vehicles in Indonesia due to the controversial nature of the transition. The opinion is transmitted through YouTube by taking comment data, then grouped into a topic to identify public opinion. The topic modeling method used is a BERTopic transformer model using IndoBERTweet in embedding. Once public opinion is modeled into a topic, changes in public opinion are evaluated using coherence score metrics and topic diversity as a measure of the consistency and diversity of the topic. The resulting topics have a coherence value of around 0.6 to 1 and a diversity value of 0.95838. This indicates that the resulting themes have strong semantic similarities and high diversity in terms of word usage and capture various aspects of text documents well.
