The Application of Augmented Reality as a Learning Medium for Acid-Base Reactions

2026-07-09T04:07:06+00:00

Chemistry learning at the junior high school level often faces challenges because many concepts are abstract and difficult to imagine, such as acid-base reactions. To overcome this, Augmented Reality (AR) technology can be used as an interactive and engaging learning medium. This study aims to develop an AR-based learning medium that can help junior high school students understand the concept of acid-base reactions in a more visual and enjoyable way. This medium displays 3D simulations of acid and base solutions, indicator color changes, and reaction results directly through devices such as smartphones or tablets. The results of the trial show that the use of AR in learning can increase students' interest in learning, understanding of concepts, and active participation in class. With an attractive and easy-to-use display, AR is an innovative solution to bring students closer to chemistry concepts that were previously difficult to understand.

The development of information technology has had a significant impact on the transportation sector, particularly in improving service quality and customer satisfaction. One example of this is the development of a web-based tourist bus rental information system, which can overcome various obstacles in manual systems such as recording errors, information delays, and inefficient schedule management. PO Hariono Trans, a bus company operating in Sidoarjo, currently still uses conventional methods in managing fleet rentals. To address this challenge, this study proposes the development of a web-based information system using the Agile method. The Agile approach was chosen for its flexibility in responding to changing needs and its ability to improve collaboration and system development efficiency.Based on the results of testing using the Black Box Testing and User Acceptance Testing (UAT) methods, the system showed good performance with a 100% success rate in functionality testing and obtained a satisfaction score of 93% from 15 respondents. Thus, the developed system has proven to be effective in improving operational efficiency and providing easier and more responsive rental services for PO Hariono Trans customers.

This research conducts an information systems audit at the Language Center of Muhammadiyah University Sidoarjo using the COBIT 5 DSS domain framework. The audit aims to evaluate system reliability and efficiency amidst operational issues such as restricted website access and TOEFL certificate printing failures. Data collection involved interviews with unit leaders and technical observations. Results show maturity levels ranging from 2.1 (DSS03 - Problem Management) to 4 (DSS06 - Business Process Controls). Critical gaps include the absence of a ticketing system and backup automation. Recommendations focus on implementing centralized incident management and cybersecurity training. The study provides a governance model for optimizing language service systems in higher education institutions.
