Abstract

Gejala merupakan suatu unsure penting dalam menentukan suatu pasien mengidap penyakit tertentu.Dalam kehidupan nyata, dokter akan menanyakan gejala-gejala pada pasiennya sebelum ia menentukanpenyakit pasiennya. Dibuatnya software ini mengambil cara kerja dokter dalam menganalisa pasiennya. Carakerja software menggunakan metode forward chaining dalam menentukan prediksi awal suatu penyakit setelahpasien memasukkan gejala yang dideritanya. Kemudian dari prediksi penyakit awal, software menggunakanmetode backward chaining dalam menanyakan gejala-gejala lain yang pasien belum masukkan.Software ini dibuat dengan menggunakan metode Fuzzy Set dalam mengolah data pada knowledge-basedsistem. Metode Fuzzy mengenal kebenaran secara parsial. Hal ini sangat berguna agar sistem yang dibuatmemiliki kecerdasan menyerupai manusia. Metode Fuzzy Set merupakan generalisasi dari crisp set dimanaelemen dalam suatu set mempunyai nilai interval 0 sampai dengan 1. knowledge-based system dipakai untukmenyimpan informasi dari pakar tentang hubungan antara gejala dengan suatu penyakit menurut intensitas danfrekuensi.Aplikasi dibuat dengan bahasa pemrograman Delphi 6.0 dan Microsoft Access sebagai mediapenyimpanan knowledge-base-nya. Pengujian software ini adalah dengan memasukkan beberapa gejalakemudian sejauh mana software mampu membuat kesimpulan penyakit yang mengandung gejala-gejalatersebut.Kata kunci: Gejala, penyakit, forward chaining, backward chaining, fuzzy set, fuzzy, knowledge based

Abstract

Japanese language uses thousands of characters for its writing system. A system called Input Method is used to enable the inputs of those characters using a standard keyboard. Some Input Method applications were already developed, from the desktop application to the web-based application. Unfortunately, those applications are not flawless. In this research, an application using the Input Method system has been developed to cover the weaknesses of those applications that already developed before. This Input Method application system uses standard web technology. Such as JavaScript on the client side. PHP on the server side. MeCab: Yet Another Part-of-Speech and Morphological Analyze dictionary is used for its dictionary. The core algorithm uses Longest Match Method for word searching.

Abstract

Association rule mining searches for interesting relationship among items in a large data set. Market basket analysis, a typical example of association rule mining, analyzes buying habit of customers by finding association between the different items that customers put in their shopping cart (basket). Apriori algorithm is an influential algorithm for mining frequent itemset for generating association rules. For some reasons, Apriori algorithm is not based on human intuitive. To provide a more human-based concept, this paper proposes an alternative algorithm for generating the association rule by utilizing fuzzy sets in the market basket analysis.

Abstract

Along with the growth of Technology, the usage of digital signage for a communication device is common in this digital world. And now Petra Christian University starting using digital signage that named DIVo. But for measuring this device are effective or not we need someone to count every person who pass by this device, and we need to count how many person who many readers who read DIVo as well. But for getting the data manually there will be many error. For example there will be human error that can make a mistake for counting how many person that passing by DIVo twice or even more, and we need many human resource to do this work because there are more than one DIVo in Petra Christian University.So we need some device that can detect people who passing by DIVo, and can detect thre reader face, and all of that thing can be done by using Kinect. Kinect is a device that made by Microsoft for gaming console named Xbox, this device is a input unit for Xbox so player doesn’t need a controlling device at all just using their body for playing. And using skeletal tracking and Face tracking inside Kinect SDK, this application can count how many person that passing by DIVo, and count how many person that read the DIvo and count how long the reader read DIVo. And using this device we can overcome this problem if we counting traffic using manual method.

Abstract

Along with the growth of Petra Christian University, more college students and guests will come to visit this university. Petra Christian University has more than few buildings and it does not rule out the possibility that new buildings will be build later. Then, Petra Christian University will need location maps and directions to help visitors of the university find specific locations inside campus area. There are physical and digital maps of Petra Christian University, and a Final Project which displays few floor maps of Petra Christian University. But an application which especially provides an interactive map and virtual tour of Petra Christian University hasn’t been made.Thus, a system is being developed, which has two separate applications. The first application is an Android-based apllication called Petra PanoraMap, its goal is to provide interactive maps for Petra Christian University. This application provides a virtual tour for users which displays panoramic views of several locations inside Petra Christian University. The second application is a web-based application called PanoraMap Editor, its goal is to provide all data and pictures needed by Petra PanoraMap. Thus, it is needed to create a data structure that can represent Petra Christian University as a whole entity based on object-oriented approach.Tests have been performed to both Petra PanoraMap and PanoraMap Editor. Petra PanoraMap application can display panoramic views so that users can feel that they are inside Petra Christian University. It is proved that PanoraMap Editor application can produce a type of data that can readily deployed into and read by Petra PanoraMap, so that contents and panoramic photos inside Petra PanoraMap is a dynamic data.

Abstract

Rendering is the process by the end of the whole process of modeling or computer animation to change the form of three-dimensional objects into two dimensions. One popular method of rendering known today is ray tracing. Ray tracing is a technique for generating an image by tracing the path of light through pixels in the image.Ray tracing method is able to produce realistic images because it is calculating lighting effects such as ambient, diffuse and specular. Reflection and refraction of light is also calculated in ray tracing. In addition, ray tracing method is divided into two kinds, known as the tracing rays from the eye (backward ray tracing) and tracing rays from the light source (forward ray tracing).Caustic effect produced by emitting light in a transparent object. Refracted light will gather in an area so that the area will appear brighter than the surrounding areas. In previous studies, the effect of caustic applied to the primitive object, where the light checks done once per object. In this study, the object used is mesh. Checking the light will be performed on each triangle in the mesh.Results showed the greater refractive index, the more caustic effect gathered in certain areas of the body bare round, but spread on a flat and taper grounded object. The increase in the complexity of the mesh will increase linearly time. Comparison with other software shows the difference in the form of caustic effects and rendering time.

Abstract

Internet technology has shown its significant growth. It affects human habits in how they seek and gather information. News has become human’s daily needs. There are so many kind of news to be read, but time is limited. Therefore, recommendation feature for news feature nowadays is needed, so it is easier to supply what kind of news that readers read, where user can rate the news.These research focused on recommendation feature for news feature based on Android. To give recommendation feature, there will be a certain server required to grab news data from some specific websites. Then, news data which was grabbed is parsed and processed to be used for members profile calculation.Based on the research, rating can change news recommendation which is given from time to time and there are still some flaws on HTML structure and RSS standard from Indonesian news websites.
