<![CDATA[This study aims to design interactive multimedia for computer network courses with Android-based so that it can be accessed via smartphone. Computer Network course is one of compulsory subjects in Informatics Engineering course. With the realization of multimedia is expected to shorten the learning time of students, and students can more easily understand the material of computer networks rather than through the tutorial tutorial as usual, and is expected to improve learning achievement. This multimedia realization chose to use the Android operating system to be accessible memlaui smartphone that is currently widely used by the students. This interactive multimedia presents theories, simulations and problems as the evaluation of computer network learning. The results of this interactive multimedia will be tested through the test instrument to the students on the study program of Inormatika Technique of Janabadra University. Instrument test used to know student achievement. Test instrument used is a questionnaire instrument to determine the quality of interactive multimedia computer network courses. Multimedia is designed using the main software such as Macromedia Flash, Macromedia Director, and Macromedia Authorware and Eclipse 4.2 along with supporting applications. The material to be delivered on interactive multimedia is tailored to the syllabus of computer network courses on Strata 1 level.

<![CDATA[Often times consumers have difficulty in determining the brand and type of digital camera that will be purchased, this is due to so many brands and competitive prices offered by the digital camera manufacturer. Required a system that can select and classify criteria selected by consumer.The purpose of this research is to design and build prototype of digital camera selection decision system that can help provide solution and recommendation to prospective buyer of digital camera using MADM (Multi Atribute Dicision Making) with Weighted Product (WP) method. The prototype of this decision support system is designed to have six digital camera criteria including camera brands desired by potential buyers, prices from digital cameras, resolutions desired by buyers, desired zoom size, camera lenses and batteries from digital cameras. according to the needs and criteria desired.

<![CDATA[Water is an important nutrient needed by the body. Dehydration is a condition when human body tissue loses fluids abnormally and this is very often underestimated so that sometimes severe dehydration can cause death. However, for now the detection of dehydration is only based on the analysis of the health team with several clinical signs of dehydration. From these problems, it is necessary to have research related to automation systems to detect levels of dehydration that can be used by ordinary people, so as to reduce the number of dehydration sufferers who are not treated because they do not know the symptoms of dehydration from the start.The purpose of this study is to develop a screening application to identify the level of dehydration in the human body that combines CBR (case base reasoning) and CF (certainty factor) methods to achieve higher accuracy values. With this screening application, it is hoped that users can easily and quickly find out the level of dehydration they experience based on the symptoms they feel and also get information about solutions for treatment or treatment that need to be done before coming to the health center or to the doctor.Based on the results of the screening application trial of 15 respondents to identify the level of dehydration in the body, it showed 60.03% stated good with an average overall score of 3.87 for the user interface aspect. The software engineering aspect shows 53.35% states good (agree) with an average overall assessment score of 3.92 which indicates that the screening application system developed and made can be used as a reference to help users or users determine the level of dehydration of the body. Keywords: Dehidrasi, Skrining, Case Base Reasioning, Certainty Factor. ]]>

<![CDATA[The phenomenon of technological development can transform systems in various sectors to provide efficiency and convenience at a lower cost, including the financial sector. Flip is a financial service application that makes it easy to transfer money between banks without administrative fees. By the end of 2021, the Flip will have a 4.9 rating on the Google Play Store. The purpose of this study was to analyze user sentiment towards the Flip app to see if flip user ratings were as positive as the ratings received. This study uses a set of text mining processes on the user rating data of the Flip app on the Google Play Store, using the classification algorithm K-Nearest Neighbor with TF-IDF weighting. The results show that 77.67% of the test data are correctly classified as positive evaluation classes, with high accuracy and recall rates of 82.67% and 86.92%, respectively. In addition, from the results of applying the Flip user rating data classification method, the comparison between training data and test data is 80%:20%, and the classification accuracy using the K-Nearest Neighbor algorithm is 76.68%. User reviews of the Flip app have shown positive results, as well as the ratings obtained in the Google Play Store and the K-Nearest Neighbor algorithm, TF-IDF weighting process used to analyze user sentiment towards the Flip app.]]>

<![CDATA[Database ini dibuat dengan menggunakan MySQL, yang melewati tahap analisis dan perancangan. Begitu pentingnya era digital atau era data pada saat ini, tidak heran administrator database berhati-hati dalam memberikan batasan hak akses kepada pengguna, dimaksudkan agar data atau informasi dapat dijaga dan tidak setiap pengguna dapat mengakses data atau informasi dari setiap tabel. Adanya batasan hak akses ini dapat menjamin keaslian isi dari database yang dibuat oleh administrator, setiap transaksi yang dilakukan oleh pengguna yang bukan administartor memiliki hak akses terbatas untuk mengelola isi database, dengan begitu keamanan yang dimiliki sistem database ini cukup baik. Untuk menjaga keamanan data atau informasi yang ada di database diharapkan memiliki back-up datanya, dikarenakan untuk mengantisipasi jika terjadi kehilangan dan kerusakan data]]>

<![CDATA[The title of this study was Retrieval Citra Batik Pesisir. The purpose of this study is how to measure the similarity between the query image to the image database on the image of a very diverse coastal batik influenced by the geographical location of the islands, the state of nature, and the structure of society, by implementing the transformation method curvelet fast discrete and HSV color space. And knowing the average yield precision image retrieval based coastal batik content using relative method manhatan. This research uses experimental analysis on coastal batik image dataset of the query image with the image in the database. Coastal batik image data taken are secondary data from the internet already results reproduk regardless of noise and shooting techniques. Applications are designed and built in stages as a test prototype image retrieval coastal batik using programming language Matlab R2014a. Based on the description of explanation and discussion on the overall chapter thesis for image retrieval batik to determine the extraction of the best features that the average value of precision curvelet scale of 4 to 85.17%, curvelet scale of 5 namely 88.62%, curvelet scale of 6 average precision value ie 90.73 %. For the average value of precision for HSV color space by 81.55%. As for the average value of precision curvelet scale 4 and HSV color space by 83.44%, to curvelet scale of 5 and HSV color space by 85.34% and to curvelet scale 6 and HSV color space by 87.71%. From this it can be deduced that the higher the measurement scale, the average precision is getting better at the time of image retrieval.Keywords: Content Based Image retrieval, Transformasi Curvelet Fast Discrete , Ruang Warna HSV , Relative Manhatan, Precision.]]>
