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 research objective was to design a teacher attendance application that has a camera feature to take pictures during teacher absences so that it can simplify and speed up attendance requests for absences from work, leave, permission and illness. The prototype method is used as a tool to develop a model into a system with stages which include; gathering requirements, building prototypes, evaluating, coding attendance systems, conducting testing, evaluating, and finally using presence applications to see the functions of the applications being built. The results of this study have produced a prototype of teacher presence at SMKN Pakisjaya based on face recognition using OpenCV and implementing the Local Binary Pattern Histogram (LBPH) as an algorithm for detecting faces from images.

The hotel is a resort for Jakarta and out of town people. Not all hotel locations are known to the public. Both in Jakarta city and out of city.
