The Yamaha Showroom is a place for repairing and selling spear parts. Not all Yamaha showroom locations can be known by the public, both those from the City of Tasikmalaya and those from outside the city. This is due to a lack of information about the Yamaha showroom in Tasikmalaya City. This study aims to build an android-based Yamaha showroom search application as a source of information to find out the location and route to the showroom location in Tasikmalaya City. The application design method involves modeling using UML (Unified Modeling Language) and location-based service (LBS) applied to the Yamaha showroom search application that was built. The results of the research resulted in a Yamaha showroom search application in Tasikmalaya City that can help the community in finding Yamaha showroom locations in Tasikmalaya City. This showroom search application in the city of Tasikmalaya can help show the direction to go. This application provides information about the opening hours and location of the Yamaha showroom. The LBS method applied to this application is for coordinate points that are more accurate and can be used anywhere and anytime by the public and easy to use.

The Jakarta Health Training Center, the Hang Jebat Campus, is a government agency that operates in the health training center to facilitate room reservations. So far, the Jakarta Health Training Center, the Hang Jebat campus, accepts reservations via telephone, fax, or consumers come directly to the Jakarta Health Training Center, Hang Jebat Campus. The purpose of this research is to build a web-based application program that is expected to have a very important impact in getting accurate and fast information and to design a web-based guest reservation application by making it easier for participants to make room reservations online and can control the number of training participants if it is limited to the maximum. So that the work becomes more effective in terms of time for reservations for both guests and receptionists. The system development method used is the Rapid Application Development (RAD) method. Based on the results of the study, to overcome the problems that exist in the Jakarta Health Training Center, Hang Jebat Campus, from the overall results of this study, it can be concluded that the Application Design of the Guest Reservation System for the Jakarta Health Training Center, Hang Jebat Campus, Guest reservation application at the Jakarta Health Training Center, Campus Hang Jebat is very interesting in terms of appearance because there are several features that are easy for guests and receptionists to understand.

PT. Pena Berkah Ilmu is a medium-sized company engaged in Food & Beverage, social and humanitarian institutions, event organizers, travel and merchandise sales where this company still implements attendance methods such as signatures for employees. The attendance of each employee is recorded through the existing attendance system. However, in its implementation, sometimes there are some persons who do not attend or forget to attend. This results in the employee being considered absent. This desire arose because this company experienced difficulties in processing attendance information data, resulting in more and more hardcopy archives and making it difficult when the company's management intended to recap and re-collect data and employee attendance lists. This study uses the waterfall method which describes a systematic and sequential approach to software, starting with the specification of employee requirements, design, modeling, construction, delivery of the system to employees and complete software support that is produced. With this attendance application, it will be easier for employees to carry out attendance attendance even though they are outside the office and attendance data will later be stored in the database so that it will make it easier for the personnel department to be able to recapitulate employee data.

The research objectives are to design a web-based application that can help make the best employee selection report process easy and fast, design an application that can calculate normalization to determine criteria and weights according to the analytical hierarchy process (AHP) method, and design an application that can manage data -Alternative data needed for the selection of the best employees. The stages of data collection in this study consisted of 3 (three) stages namely; observation, interview, and literature study. UML (Unified Modeling Language) is used as an approach for modeling while the Analytical Hierarchy Process (AHP) method is applied in the best employee assessment application. The results of this study can facilitate the selection of the best employees to be faster with accurate results by using the best employee selection application by implementing the Analytical Hierarchy Process (AHP) method using the PHP and MySQL programming languages.

The research objectives are; designing a web-based information system that provides information about tourist attractions, culinary delights, and lodging in the Nagekeo district. In the application development process using the Rapid Application Development (RAD) method and modeling design using Data Flow Diagrams (DFD). From the discussion that has been described, it can be concluded that the results of this study tourists can easily and quickly get information about tourist objects, culinary, lodging around tourist sites in Nagekeo district. It is estimated that tourism development technology will continue, which is a big opportunity for companies and destinations, especially in Indonesia. There is a need for studies on tourists on cultural experiences, streaming platforms, metaverse technology, biometric payment methods so that there are innovations to attract visitors and add value to the local tourism industry through the implementation of digital solutions.
