Recently, recommender systems have been developed for a variety of domains. Recommender systems also can be applied in tourism industry to help tourists organizing their travel plans. Recommender systems can be developed by a variety of different techniques such as Content-Based filtering (CB), Collaborative filtering (CF), and Demographic filtering (DF). However, the uses of these techniques individually will have some disadvantages. In this research, we propose a hybrid recommender system to combine the predictions from CB, CF and DF approaches using neural network model. Neural network model will learn by processing a training dataset, comparing the network’s prediction for each dataset with the actual known target value. For each training dataset, the weights are modified to minimize the mean-squared error between the network’s prediction and the actual target value. The experimental results showed that the neural network model outperforms each individual recommendation techniques. Index Terms - Colaborative Filtering, Content-based filtering, Data Mining, Demographic Filtering, Hybrid Recommender System, Neural Network

Dictionary is a reference book that contains words and phrases that are usually arranged alphabetically and followed by description of the meaning, usage, or translation. Dictionary has several kinds, one of which is a dictionary of terms. Medical Dictionary is a dictionary of terms that contain medical terms. Medical dictionary identical with the thick book that complicated and slow in its use. To overcome this we need a medical dictionary application. Medical dictionary applications require a search process to support the performance of the application. Search process is needed to shorten the time in the search itself. Searching is done using the Boyer - Moore algorithm is a string search algorithm that has the fastest searching time, because the strings match moves from right to left, so can shorten the time and simplify the use of medical dictionary application. This research was made based on Android using Java programming language with SQLite databases. After testing, 100% of 45 respondents stated that the application of this medical dictionary has the accuracy of the resulting word in the search process. Index Terms - medical dictionary application, search string, Boyer-Moore algorithm, Java, SQLite

With the proliferation of video streaming services, now internet TV has become a popular service on the Internet. Catch-up TV is an attractive service in internet TV, where user who misses a live programme can watch it later. Meanwhile, not all streaming protocols, by default, are able to support catch-up TV application. This paper explains how to develop catch-up TV application in RTSP/RTMP streaming protocol, by doing shell-script programming and using Wowza streaming engine, on Linux-based streaming server. The research result has been implemented in UseeTV, one of the largest commercial internet TV service in Indonesia.

Augmented Reality is a technology that can project objects from the virtual world to the real world. Augmented Reality continues to be developed so it can be easy to implement into various devices. However, the device must have a camera, VGA card, and the ability to process data that is high enough to be able to process and projecting graphical data that captured by the camera and displayed to the screen. Marker-based Augmented Reality is still better than Markerless Augmented Reality due to several issues such as disturbances in the geomagnetic sensor that is used to map the Y axis and Z device that belongs to the user.

One of mental disorders that is often experienced by the population in Indonesia is anxiety and depression. Those disorders can interfere the activity if they are not handled properly. However, the lack of public knowledge of the symptoms of anxiety and depression, as well as the reluctance to consult a psychologist, can make the handling becomes too late. This problem can be overcome with the webbased application to detect anxiety and depression in the public. This application is made through several stages that begin with the literature study, interviews with psychologists, analyzing the needs of both application and database. The evaluation of this application is done by distributing questionnaires to 45 respondents who have tried to use this application, as well as functional and validity testing by psychologists. The results of the evaluation states that every feature in this application is functioning well, is easy to use and in accordance with the code of ethics of psychology.
