The number of collections in a library will be increase along with the growth of the library. The Library of Universitas Kristen Duta Wacana (UKDW) also has a large number-of books collection in order to provide literature and resources service to students. Wen the number of collection is very large, we need a retrieval system that will help anyone to find the needed resoLtrces. This system has a recommendation feature to provide related books or resources. This feature will help users to find similar literature/resources or related topic with what they need. This paper will describe about the main design and implementation of the book recommendation based on FP-Growth algorithm. Based on the experiments, this system can provide 60.78% of accuracy for related books recommendation.

Security and confidentiality of information are considered a requirement in today's communication media. Many people have used Internet to share and distribute confidential information. On the other hand, many malicious activities attempts to steal those information by irresponsible parties. Therefore, information must be secured and converted into another form before it is sent to the destination by the use of cryptography and steganography. We developed a program to secure this information, by using Twofish and Least Significant Bit algorithm to encrypt secret messages and then insert it into an image file. By combining these two methods, we can achieve higher levet of information security.The information encoded with twofish algorithm will change the fite size stightly. This changes are caused by the use of padding. In addition, both of the output image are not resistant by some manipulation operations. The output of the system in BMP format does not change the file size after insertion process, while PNG format will have a stightty dffirence infile size due to processing in bitmap mode.

PERANCANGAN PROTOTYPE VIRTUAL MUSEUM KERATON KASUNANAN SURAKARTA HADININGRAT BERBASIS WEB Stefanie G.N.L. Worang; Michael Bezaleel Wenas; T. Arie Setiawan Prasida; Andeka Rocky Tanaamah

Museum of Keraton Kasunanan Surakarta Hadiningrat is a museum located in Solo that saves a lot of cultural heritage objects of Java. But the limitation of time, cost, and location cause not everyone can see directly the objects, so the access to that objects are limited. Prototype Virtual Museum Keraton Kasunanan Surakarta Hadiningrat which utilize Web-based 3D Web Technology is expected to increase public accessibility to the historical objects as well as instructional media and the delivery of information interesting and interactive in order to preserve the cultural heritage and the development of Java.

Developing video search application using the service of a third party data (resources) provider is a complex process. Therefore to obtain the desired data, an efficient communication method is needed. This research explored the use of REST request communication method by using URL to identify video resources through YouTube API data. Video data that were identified will then be processed to get more relevant video search. Relevancy of the search result was determined by applying the mechanism of relevance-based system and user-based system. Based on the experiment analysis, it is concluded that key word has an important role in determining the relevance of the search result, as it is needed for timeline based representation.

IMPLEMENTASI DYNAMIC PROGRAMMING PADA PENENTUAN JENIS MATERIAL UTAMA BANGUNAN ARENA FUTSAL Andree Anthony; R. Gunawan Santosa; Yuan Lukito

Building futsal court need some planning, especially about the materials needed to build a futsal court such as synthetic grass, roofs, walls, benches, and some other materials. Each of materials have many choices usually based on quality and price. Thus it needs a system to assist on calculating the optimum materials combination based on a specified budget. Minimax Route method are used with dynamic programming techniques to maximize the quality of materials while minimizing the price of materials chosen. Based on system testing conducted to futsal court owners in Yogyakarta, the implementation are helpful and have many useful information for someone who want to build futsal court.
