Abstract

Nowadays, the computer’s technology is growing so fast and affects the human’s life. With computer, people can do something easier, faster, more efficient, and so on. At SMAN Bandarlampung, the time schedule for teaching process is still done manually. One person is in charge of doing and making the time schedule so that all the lessons, time, classrooms, and days are supposed to be fixed and suitable for every teacher. However, this is not easy to be done, because there are some factors also that must be considered, for example: teacher who also put in structural position such as headmaster or vice headmasters. Besides, under Indonesian’s regulations, the teacher whose certificate to educate must teach at least a certain hour per week. Therefore, in order to handle this condition, we design and develop a system so that the problem can be solved easily. We use the concept of edge coloring to match the schedule. The data are divided into three sets: the set of active time, the set of classes and classroom, and the set of  teachers’ obligation (which include : the data of teachers and their subjects/lessons, and how many time/hours needed to teach for every teacher. The system developed is running well and we will be discussed in the paper.

Abstract

Semaphore is a medium to communicate from one person to another. The process of studying semaphore codes is quite difficult and requires a relatively long time because of the limited medium for learning this code. This research aims to design and develop the application for learning semaphore code on Android-based mobile devices as well as providing an alternative learning media for semaphore code learners. Android mobile devices selected as the basis of application development considering of the use of those Android technologies.This application was developed with the Java, HTML, CSS and JavaScript programming language. The data used are motion pictures semaphore. The application tests was carried out using the Blackbox Testing method. The testing is done by examining the functional features of the application. The test results of system and application test shows that the Semaphore Code Application is able to run well on Android operating system applied on Ice Cream Sandwich and Jelly Bean version and also able to translate words and sentences in roman letters into motion pictures semaphores.Keywords: Android, learning media, mobile devices, semaphore.
