Air pollution is a global environmental problem that is of serious concern in various regions around the world, including in Indonesia. Poor air quality has negative impacts on human health, ecosystems and economic growth. The purpose of this research is to classify the air quality in the Special Region of Yogyakarta. Classification is done using data mining techniques with the C4.5 algorithm or decision tree. The results of the analysis that has been studied using the C4.5 algorithm used 5822 data and 20 replacement samples with 100 repetitions, so the results of this study obtained 7 decisions or leaves with a success rate of 99.9485% and a failure rate of 0.0515%.

The advancement of information technology has significantly transformed operational management in various sectors, including the culinary industry. Cafe Ungu at Universitas Amikom Purwokerto serves as a campus facility offering a variety of food and beverages to students, staff, and visitors. However, the conventional ordering method relying on direct interaction often leads to long queues and recording errors, hindering service effectiveness. To address this issue, this study designs a web-based ordering information system using the Waterfall method, encompassing the stages of requirements analysis, design, development, testing, and maintenance. The system is designed to allow customers to place orders online, assist administrators in managing orders, and provide transaction data for business analysis purposes. The implementation results indicate that this system can improve operational efficiency, reduce ordering errors, and enhance customer satisfaction. Therefore, this information system is expected to be a strategic solution for Cafe Ungu in addressing order management challenges in the digital era.

This study aims to analyze user satisfaction with the Universitas Amikom Purwokerto repository website using the System Usability Scale (SUS) method. In the digital era, online repositories play a crucial role as a platform for storing, managing, and distributing academic work, supporting academic activities and knowledge exchange. However, observations indicate that the repository website faces challenges in accessibility, including unintuitive navigation, difficult-to-understand menus, and limited language options, as it is only available in English. Through a SUS survey involving 100 respondents, an average SUS score of 46 was obtained, falling into the "Not Acceptable" category with a grade of "F" and an adjective rating of "Poor." This result indicates that the website’s usability is insufficient and requires improvement. Recommendations include enhancing navigation, ensuring interface consistency, providing a dual-language option (Indonesian and English), improving website speed, and conducting regular user satisfaction evaluations. These improvements aim to optimize the Universitas Amikom Purwokerto repository website, thereby providing a better user experience and effectively supporting academic activities and the dissemination of academic work.
