Abstract

Email is one of the most common ways to communicate and exchange information inside and outside the office. The manager of the Garut Post office always holds meetings and visits outside the city so that the manager is not always in his office. At the Garut Post office there are several employees based on their level, such as permanent employees and interns. In making payroll, permanent employees do not need to communicate with the manager because it is already listed at the Garut Post office. However, interns must communicate with their manager, so this is often done by sending email messages. Based on the results of interviews conducted with the manager of the Garut Post office, according to him, messages via email are not always safe in sending personal and confidential information. According to a study, 85% of all cyber attacks that occur on companies are caused by phishing attacks via email. Phishing attacks are the most common technique used by hackers to steal sensitive information from email users. The Garut Post Office needs to have a Website-Based Application for Securing Email Messages in Images Using Advanced Encryption Standard (AES) and Least Significant Bit (LSB), so that it can increase the level of security and privacy in sending and receiving email messages for Interns and Managers. The methodology is the Extrime Programming (XP) methodology, to encrypt email messages using AES for security, as well as inserting the encrypted message into an image using the LSB method so that it is not visible. In addition, this research wants to integrate this technique into the website interface, test its security effectiveness, and contribute to the field of information security.

Abstract

Technological advances nowadays continue to increase rapidly, where shops or entrepreneurs who run their business using technology will provide advantages in doing business. Meanwhile, shops that do not have information technology in business will easily be overtaken by other shops, such as the Pitbox shop where sales have decreased due to the lack of technology in marketing products, making it difficult to reach potential customers and the lack of information is not conveyed to consumers. . This research aims to develop a website-based application that uses Augmented Reality (AR) technology to assist Pitbox shops in marketing motorbike accessory products. The main objective is to provide marketing media that can convey complete information about motorbike accessory products to consumers. The method used in this research is the Multimedia Development Life Cycle (MDLC), which consists of six stages, namely concept, design, material collecting, assembly, testing, and distribution. Augmented Reality technology is used to integrate AR features into the website applications being developed. The results of this research show that this application allows users to view motorbike accessories in real-time, provides complete information about the product, and improves consumer experience in selecting and purchasing motorbike accessory products.

Abstract

The application of sophisticated Augmented Reality (AR) technology in providing information about campus facilities is an innovative and effective approach. Continuous research is developing an Augmented Reality application that will provide a visual display of the facilities on the Garut Institute of Technology campus. This research effort is to change the Augmented Reality approach which previously focused on layout displays to place more emphasis on virtual displays of facilities, so that they are easier for students to understand. The research method used is Research and Development (RnD) carried out using the ADDIE development approach, which involves the sequence analyze, design, develop, implement and evaluate. Application development is carried out using Visual Studio Code software. The results of this research show a virtual visualization of campus facilities, including various areas such as classrooms, parking areas, canteens, prayer rooms, and language laboratories. Users can access visualizations of these facilities via smartphones and other hardware, allowing them to view these facilities in virtual form and with detailed depictions of campus facilities. The results of testing user satisfaction with the application show a very good level of acceptance.
