Keamanan rumah merupakan salah satu permasalahan dalam kehidupan sehari-hari. Kecemasan sering melanda disaat kita meninggalkan rumah. Namun, dengan penerapan sensor PIR yang dapat mendeteksi gerakan dan sensor magnetic switch yang dapat mendeteksi pintu yang terbuka, kita dapat mengetahui kemungkinan adanya penjahat yang masuk ke rumah. Selain itu fungsi SMS Gateway juga dapat dijadikan sebagai salah satu fitur untuk mengirimkan notifikasi pemberitahuan adanya gerakan dan status pintu yang terbuka kepada pemilik rumah. Penelitian ini bertujuan untuk membangun prototipe sistem keamanan rumah yang menggabungkan sensor PIR dan magnetic switch berbasis mikrokontroler dan SMS gateway. Metode yang digunakan adalah prototyping. Hasil pengujian sensor PIR dapat mendeteksi gerakan dengan jarak terjauh 5 meter, sedangkan sensor magnetic switch dapat mendeteksi pintu yang terbuka maksimal 2 centimeter. Notifikasi SMS juga berhasil dikirimkan kepada pemilik rumah setiap kali ada gerakan atau pintu yant terbuka yang terdeteksi oleh sensor.
The number of smartphone and internet users in Indonesia is currently very large. This is become the basis for the use and development of mobile-based applications for the advantage of education. However, not all High Schools in Indonesia have a mobile-based system. Another problem is that most of them still use conventional methods in implementing teaching and learning activities, and reporting learning outcomes to parents. This is also still the case at SMA Negeri 1 Pangkalanbaru, Bangka Tengah. This problem is what we want to raise and solve by developing applications that can solve these problems. The research was developed using the Prototype method which consists of stages of Data Collection, Rapid Planning, Prototype Design, and Prototype Testing. By using the UML tool, results are obtained in the form of parents who can monitor grades, school information, and school announcements. In addition, students can take attendance online, register for extracurricular activities, and view announcements. From the testing results it is known that the system performance is running well as it should.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
