Abstract

The exact handling to the postoperative inpatient of the major operation in the restoration period, became one of the factors that very important for the success of the process of medical treatment on the whole. By paying attention to the development of signs and vital signs from the patient, could be made medical by one decision took the form of the further action for the handling of the patient. Using backpropagation neural networks, could be made by a system that could carry out the prediction (forecast) the medical decision that will be taken to the postoperative patient the major's operation. After trining, by accepting sign input and the vital sign of the patient, the system could determine the action that will be carried out against the patient. From results of the test of the application program showed that the backpropagation neural networks could do the prediction of the medical decision with the success to 80%. Therefore, output from the system could be used as consideration of the doctor to decide the further action for the patient.

Abstract

Abstrak— Pada  penelitian  ini dicoba dideteksi penyisipan pesan pada sebuah citra yang dilakukan dengan  teknik Least Significant Bit. Deteksi dilakukan dengan teknik Chi-square attack. Pada teknik ini dibandingkan distribusi frekuensi yang diharapkan secara teori dengan beberapa distribusi sampel yang diamati pada stego-image.Pada penelitian ini dilakukan steganalisis terhadap 10 macam citra yang disisipi dengan sebuah pesan yang berukuran 1kb, 2 kb dan 5 kb. Dicobakan juga 2 penyisipan berbeda, yakni dengan program Stegano dan StegoGraphyBMP.Dari percobaan yang dilakukan pada sepuluh stego-image dengan panjang pesan 1kb, 2kb, dan 5kb, Chi-square attack berhasil 80% mendeteksi pesan yang disisipkan pada sebuah citra dengan program Stegano dan berhasil 70% mendeteksi pesan yang disisipkan pada sebuah citra dengan program StegoGraphyBMP. Disamping itu diperoleh hasil bahwa ukuran pesan tidak berpengaruh pada proses steganalisis. Keywords—  Steganalisis, Chi-square.

Abstract

AbstrakSebuah smartphone umunya dilengkapi dengan Global Positioning System (GPS). Pengguna smartphone  disamping dapat mengetahui lokasi dirinya, umumnya juga ingin mengetahui lokasi sekitarnya. Foursquare merupakan salah satu jejaring sosial yang menyediakan layanan berbasis lokasi. Foursquare memiliki fitur check-in, untuk menandai lokasi pengguna.Dalam penelitian ini akan dikembangkan aplikasi pada perangkat dengan sistem operasi Android yang dapat mencari lokasi fasilitas umum di sekitar pengguna dengan memanfaatkan teknologi layanan berbasis lokasi. Aplikasi ini memanfaatkan data dari Foursquare. Hasil pengujian terhadap aplikasi yang dibangun menunjukkan filter data dan sistem auto check-in berjalan dengan baik sehingga duplikasi data dalam Foursquare dapat diminimalkan.  Kata kunci— Layanan berbasis lokasi,  Android, Foursquare, Fasilitas umum  AbstractA smartphone is equipped with Global Positioning System (GPS). A smartphone user may know  the location itself, and usually want to know the surrounding location. Foursquare is a social network that provide location-based services. Foursquare has a check-in feature to mark the location of the user.This research develops applications on devices with Android operating system that can find  location of public facilities around the user by using  location-based services technology. This application uses Foursquare data.The test results showed that the application can filter data and the check-in systems running properly such that duplication of data in Foursquare can be minimized.  Keywords— Location Based Services (LBS), Android, Foursquare, Public Facility
