Abstract

The case of lost or missing children when people go traveling or in the hustle often occurs due to lack of parental supervision. These problems can be solved using Global Position System (GPS)-based navigation technology Location Based Service (LBS). This research aimed to determine the position of members of the community (such as family) who were lost or missing by using mobile devices. Rapid Application Development (RAD) was used for system development, which comprised the step of requirement or planning, system design, development, and cutover. The result of this research is a GPS-based application that is able to display the position of members of the community, the route to the location, and the media discussion (comments). The conclusions show that the application provides an easy and useful function in finding the location of the community member, displays the route to the location, and allows the interaction in the form of communication.

Abstract

Book as a learning method is less effective and interactive since it can not deliver motion animation. Thus, a more interactive learning method is needed to have a better learning process. The goal of the research is developing an application that provides easiness for students in learning algorithm by combining computerassited instruction (CAI) and internet technology. On the development phase, the research methodo uses fact finding by a survey to students who are or have been learning algorithm and a literature study, and also waterfall method for software development. The research output is a CAI application for learning algorithminteractively. The developed application is interactive for learning process and able to help students in deepen algorithm topics.

Abstract

Along with the growth of social media, a variety of potential threats to users is also increasing. These kinds of threats often occur because the users accidentally or unknowingly disclose their information or identity on social media. Threats resulted from the disclosure of information are needed to be known so that the users can understand the risks that arise and take precautions. This research was aimed to summarize the potential threats arising from the information disclosure in social media. The research method used was a systematic literature review to explore and summarize the literatures that discuss the specific topic. The research results show that the potential threats are mostly social threats and identity theft.

Abstract

Bahasa Inggris saat ini masih menjadi bahasa yang popular, banyak dipelajari, sebagai bahasa internasional, dan tercakup dalam kurikulum pendidikan di Indonesia. Penguasaan kosakata memberikan kontribusi yang penting dalam kemampuan seseorang dalam menguasai bahasa Inggris. Penelitian sebelumnya menyatakan bahwa metode pembelajaran yang menerapkan Computer-Assisted Instruction (CAI) dapat meningkatkan aspek pemahaman dan motivasi karena penggunaan media yang menarik. Penelitian ini bertujuan untuk menerapkan konsep CAI sebagai perangkat ajar untuk pembelajaran bahasa Inggris. Hasil dari penelitian ini berupa aplikasi perangkat ajar CAI yang berbasiskan permainan untuk meningkatkan penguasaan kosakata bahasa Inggris. Metodologi perancangan menggunakan waterfall yang meliputi tahapan user requirement, analisis, desain, pengkodean dan pengujian, implementasi, dan pemeliharaan. Simpulan yang didapat dari ujicoba terhadap responden yaitu perangkat ajar CAI mampu meningkatkan penguasaan kosakata, meningkatkan kecepatan pengguna dalam membaca, dan meningkatkan kecepatan mengetik kosakata bahasa Inggris.

Abstract

Boolean Retrieval (BR) and Vector Space Model (VSM) are very popular methods in information retrieval for creating an inverted index and querying terms. BR method searches the exact results of the textual information retrieval without ranking the results. VSM method searches and ranks the results. This study empirically compares the two methods. The research utilizes a sample of the corpus data obtained from Reuters. The experimental results show that the required times to produce an inverted index by the two methods are nearly the same. However, a difference exists on the querying index. The results also show that the numberof generated indexes, the sizes of the generated files, and the duration of reading and searching an index are proportional with the file number in the corpus and thefile size.

Abstract

Tourist place navigation application becomes more important for travelers, especially backpackers. Previous research had produced applications which can only show the route from the position of traveler to tourist place with map shown. The goal of the research is to use the radius and rating method that is still rare in the community to navigate tourist place. Output of the research is a GPS-based application that can display the search results of tourist sites based on rating and radius method, route from the traveler to the destination place, and description of the place. Development method used waterfall that contained user requirement, analysis, design, coding and testing, implementation, and maintenance. Conclusion of the research has shown that the developed application provided convenience in searching tourist places based on radius and rating, displaying route, and description of tourist places.
