Metode Analytical Hierarchy Process (AHP) merupakan suatu metode yang digunakan dalam pengambilan keputusan terhadap penentuan prioritas pilihan dari berbagai alternatif. Pendekatan yang dilakukan dalam AHP adalah analisis permasalahan keputusan kriteria majemuk melalui prinsip-prinsip dekomposisi, analisa perbandingan, dan sintesa prioritas. Pada matriks yang dihasilkan akan dicari bobot dari tiap kriteria dan alternatif dengan menormalkan rata-rata geometrik. Bobot prioritas global diperoleh dengan mengalikan bobot prioritas lokal dari kriteria dengan bobot prioritas lokal dari alternatif. Analsis sensitivitas dalam AHP dilakukan dengan mengubah bobot prioritas dari kriteria keputusan. Bobot prioritas kriteria tersebut diubah lebih kecil dan lebih besar dari bobot sebelumnya, sehingga diperoleh perubahan urutan prioritas tanpa pengambilan data ulang. Kata Kunci:analisis metode, metode AHP, pemilihan sekolah

Women with type B personal disorder tend to have high risk of violence. It is important to make early detetction of this personal disorder, so that it can be anticipated properly. This paper reports an architecture model of back propagation neural network (BPPN) for early detection of type B personal disorder. The back propagation process divided into two phases, i.e training and testing. The training process used 43 data and the testing process used 34 data. The output classified into 4 diagnosis category of type B personal disorder, I.e. anti social, borderline, histrionic, and narcissistics. The optimal parameters of BPPN model consist of maximum epoch of 1000, maximum mu of 10000000000, increase mu of 25, decrease mu of 0.1, and neuron hidden layer of 25. The MSE of training is 3.07E-14 and MSE of testing is 1.00E-03. The accuracy of training is 90.7%, while the accuracy of testing is 97.2%.

Abstract

Indonesia is a country that is rich in culture and customs. Indonesia also has great potential in the field of tourism, especially cultural tourism. The key to attracting tourist visitors lies in the information media provided. In this paper, a desktop-based application is developed with 3D virtual reality graphics model technology with Tongkonan traditional house from the Toraja tribe and their environment as the object. This 3D virtual reality visualization aims to be an interactive promotional media for the millennial generation in introducing cultural tourism, especially the Tongkonan traditional house of Toraja. In this application, the user can explore the traditional house objects as a whole – with the help of navigation control in the form of keyboard and mouse. The ADDIE model method was used in designing this desktop application. The user response test was used to measure respondents' attitudes toward the application using the Likert scale and succeeded in getting the very good category in 17 questionnaire statements and the good category in three questionnaire statements. Therefore, it can be concluded that the VR visualization of Tongkonan Traditional House can act as an interactive promotional media to the millennial generation.
