The rapid advancement of technology has transformed many aspects of life, including education. Information and Communication Technology (ICT) plays a crucial role in enhancing the quality of learning. One promising technology is Augmented Reality (AR), which offers interactive elements to clarify complex concepts. Based on conversations with a history teacher at SMK Media Informatika, the teaching methods currently used tend to be traditional. Therefore, an AR-based history learning application focusing on the Ancient Mataram Kingdom in Indonesia was developed using the ADDIE Method. This application was created using Unity 3D and the C# programming language. It serves as an interesting addition for students, aiming to increase their interest in learning. The hope is that this research will significantly contribute to the history learning process, providing innovative, effective, and enjoyable media.
 

 PT Hong Xin Printing Equipment is encountering obstacles in improving operational efficiency and managing human resources in the digital age. Despite the use of a fingerprint attendance system, there are concerns about errors and reduced efficiency due to manual data processing. Additional challenges arise when recording attendance for employees on business trips and manually calculating leave. To tackle these issues, the company is planning to create a web-based payroll system that will automate payroll, attendance, and leave management. The implementation of this system is anticipated to enhance efficiency and accuracy, thereby allowing the company to maintain its competitiveness in the market.

PT Cempaka Mega Mandiri is a company engaged in processing and selling swallow's nests, both for export and in the local market. Currently, it is known that the attendance system used in this company has an unsatisfactory level of accuracy. Therefore, the author decided to apply GPS technology to increase efficiency in the attendance process, in the hope of providing a better solution for the company. GPS, which stands for Global Positioning System, is a navigation system that uses satellites to identify and synchronize location data from an object on the earth's surface. In this context, the application of GPS technology is considered a strategic step to increase the accuracy of recording employee attendance. This research uses the SDLC Waterfall method as a software development approach. This method involves sequential stages, starting from planning, analysis, design, implementation, testing, to maintenance. The result of this research is the development of a GPS-based attendance website, which is expected to provide an effective solution for improving the attendance system at PT Cempaka Mega Mandiri.
