Augmented reality is a visual technology which combines virtual objects into the real environment in real time. E-tourism in Bali needs to be optimized, so that information technology can help tourists and provide new experiences when traveling. Generally, tourists wish for gaining information in an attractive way about visiting tourism objects. Nowadays, mobile-based application programs that provide information about tourism objects in Bali are rarely found. Therefore, it is important to develop an application which provides information system about tourism objects, especially about the Tanah Lot temple. By implementing augmented reality technology, which grows rapidly all over the world, the application of DewataAR can show 3 dimensional objects, video, and audio information of the temples. The application works by scanning brochure of tourism object by using an Android smartphone or tablet, then it can display 3 dimensional objects, video, and audio information about those tourism objects. Hence, augmented reality can be alternative media for promoting tourism object attractively for tourists and also be able to develop tourism in Bali.
Pendidikan merupakan sarana untuk memajukan sumber daya manusia. Mewujudkan kemajuan pendidikan, memerlukan suatu alat untuk mengelola data seperti data kurikulum, siswa maupun nilai. Alat tersebut nantinya dapat digunakan untuk mengontrol kegiatan siswa di sekolah sehingga hasil informasi dapat segera tersampaikan dan proses monitoring dapat berjalan efektif karena adanya komunikasi antara pihak sekolah dan orang tua. Sistem Informasi Monitoring Perkembangan Anak di Sekolah Taman Kanak – kanak Berbasis Cloud merupakan sebuah layanan Software As A Services (SaaS) berbasis web. Sistem informasi ini dibuat dengan menggunakan teknologi cloud yang memberikan fasilitas untuk melakukan pengelolaan berbagai data akademik seperti data siswa, nilai dan lain sebagainya. Layanan sistem informasi akademik berbasis cloud ini dapat diandalkan untuk beroperasi secara online tanpa memerlukan server dan instalasi untuk setiap sistem yang ada di sekolah. Penggunaan teknologi cloud dalam pembuatan aplikasi ini sudah dapat mempermudah proses manajemen data akademik dan data sekolah yang umumnya dilakukan secara konvensional. Hasil penelitian yang dilakukan dengan menyebar kuesioner menggunakan perhitungan skala likert menunjukkan lebih dari 50% pengguna setuju dengan pernyataan yang sudah dibuat.
Abstract-Dewata Nawa Sanga in Hinduism has an important role as the foundation of the religious concept implemented by Hindus in Bali, Indonesia.
Seiring berjalannya waktu teknologi terus berkembang semakin canggih. Dimulai dari website, sampai dengan teknologi mobile. Teknologi website dan mobile memiliki peran yang sangat penting sebagai sumber informasi. iBadung merupakan sebuah aplikasi mobile yang memiliki fungsi sebagai wadah yang menyediakan berbagai jenis buku bacaan atau dapat disebut perpustakaan digital yang dapat diakses oleh semua orang. Untuk dapat mengukur tingkat kenyamanan user, kelayakan aplikasi, dan interface aplikasi maka dilakukan pengujian usability, tujuan untuk menganalisis user experience dalam penggunaan aplikasi iBadung. Fungsi dari metode Heuristic Evaluation adalah mengetahui tingkat usability pada iBadung. Pengujian ini mengisi kuesioner dilakukan oleh 17 orang responden dengan kategori pengguna awam, pengguna biasa dan pengguna administrator. Hasil yang didapat dari pengujian pertama pengguna awam mendapat nilai severity rating skala 2 kategori minor usability problem, pengguna biasa dan pengguna administrator mendapat nilai severity rating skala 1 kategori cosmetic problem. Temuan permasalahan yaitu pada logo aplikasi, tata letak icon menu, tampilan menu login, penambahan pop up exit pada tampilan aplikasi iBadung dan dilakukan perbaikan tampilan sesuai rekomendasi user selanjutnya melakukan pengujian kedua setelah perbaikan tampilan selesai dikerjakan.
SUMMARYWhen the Akebono (EXOS-D) satellite passed through the plasmasphere, a series of lightning whistlers was observed by its analog wideband receiver (WBA). Recently, we developed an intelligent algorithm to detect lightning whistlers from WBA data. In this study, we analyzed two typical events representing the clear dispersion characteristics of lightning whistlers along the trajectory of Akebono. The event on March 20, 1991 was observed at latitudes ranging from 47.83 • (47,83 • N) to −11.09 • (11.09 • S) and altitudes between ∼2232 and ∼7537 km. The other event on July 12, 1989 was observed at latitudes from 34.94 • (34.94 • N) and −41.89 • (41.89 • S) and altitudes ∼1420-∼7911 km. These events show systematic trends; hence, we can easily determine whether the wave packets of lightning whistlers originated from lightning strikes in the northern or the southern hemispheres. Finally, we approximated the path lengths of these lightning whistlers from the source to the observation points along the Akebono trajectory. In the calculations, we assumed the dipole model as a geomagnetic field and two types of simple electron density profiles in which the electron density is inversely proportional to the cube of the geocentric distance. By scrutinizing the dipole model we propose some models of dispersion characteristic that proportional to the electron density. It was demonstrated that the dispersion D theoretically agrees with observed dispersion trend. While our current estimation is simple, it shows that the difference between our estimation and observation data is mainly due to the electron density profile. Furthermore, the dispersion analysis of lightning whistlers is a useful technique for reconstructing the electron density profile in the Earth's plasmasphere.
Calculation of Gross Primary Production that utilize remote sensing data is can be done on commercial remote sensing software by manual method. The commercial remote sensing software does not provides a specific feature that allow the user to do the Gross Primary Production calculation. This research is aimed to to build a remote sensing software that can be specifically used to do the Gross Primary Production calculation for Denpasar area. This software accepts remote sensing data as an input, such as satellite image from Landsat 8 OLI and TIRS and metadata file. The formulas and supporting data that required on the Gross Primary Production calculation are implemented on software in order to make an automatic image processing software. There also some additional feature on this software such as automatic data parsing from metadata file, cropping, masking and zoom that could help user to do the Gross Primary Production calculation. The developed software is able to produce information such as Gross Primary Production value that depicted by a figure with color segmentation, area of the segments and mean, minimum and maximum value of the Gross Primary Production.
Clustering based image segmentation in this study using Fuzzy C means algorithm with Xie Beni Index as an objective function. Preprocessing applied in this model using Statistical Region merging. Spatial function applied in Fuzzy C means method to reduce noise in clustering. The system evaluation is done by measuring cluster validity value (Xie Beni Index), execution time, and number of iteration. Experimental results on three test images illustrates the proposed method able to perform image segmentation well.
