<![CDATA[The higher activity of data exchange transactions both online and offline raises concerns for some parties, large data sizes result in a waste of memory and slow data transfer and delivery processes. For this reason, a technique is needed to change the size of the data to be smaller. This technique is called compression or better known as data compression. Data compression is a process of converting a set of data into a form of code to save data storage requirements. Fixed Length Binary Encoding Algorithm (FLBE) uses a lossless technique that does not eliminate information at all, only representing some of the same information. The results obtained from the application of Fixed Length Binary Encoding algorithm in the process of compression and decompression include compression capacity, compression ratio and compression and decompression time. In accordance with the results of the experiments carried out, it can be seen that the data originally having a larger size can be compressed well implemented in text files.]]>

<![CDATA[Compressed files require less disk space than files that are not compressed, so compressing is useful for backing up data by using storage space to be small or to send information over the Internet faster. MP3 makes the audio format often used because the data stored resembles the original data when recorded and has a size that is not too large compared to other formats. Users besides storing song files, they also store videos and other files and users also want the highest quality data and minimum quantity (size). So to make a lot of empty space and have a size of data that is not large on storage media, a compression method that means to shorten the size of the bits needed for data is needed. Algorithms used in the compression process, including the Levenstein algorithm which is a type of lossless compression. Applying the Levenstein algorithm to the compression process the author wants to know the performance of compression when done by compressing MP3 files, so that large MP3 files will be compressed into smaller sizes, so that the transmission process is carried out faster and reduces the data storage location.Keywords: MP3, File, Levenstein]]>

<![CDATA[Some image files are very large in size. So it requires a large memory storage capacity too, this is certainly a lot of costs that must be spent on the storage media. With the existence of a very large image file size in the process of sending image data files can fail because the storage media exceeds the maximum limit. The above problems can be overcome by performing the process of compressing large image files into small sizes or can reduce the bit size contained in each image file thereby saving storage containers and simplifying the process of transferring image files to other storage media. The solution to this problem is how the image file can be compressed in order to speed up the transfer and storage of image files. Image file compression aims to reduce or reduce the size of the file but does not eliminate the information data in it. With the compression technique, the data was initially large so that the size of the data can be reduced so as to save storage allocation space. In this study using the Even-Rodeh Code algorithm, using the method results in very good compression in tramisi data and transfer of image file allocation easier and faster.Keywords: Image File Compression, Event Rode Code Algorithm]]>

<![CDATA[Banyak gangguan yang dapat terjadi pada citra hasil kamera digital, seperti lensa tidak fokus, muncul bintik-bintik yang disebabkan oleh proses capture yang tidak sempurna, pencahayaan yang tidak merata yang menyebabkan intensitas tidak seragam, kontras citra terlalu rendah sehingga objek sulit dipisahkan dari latar belakangnya atau gangguan yang disebabkan oleh kotoran yang menempel pada citra dan lain sebagainya. Noise yang berupa bintik-bintik dapat mengurangi keindahan sebuah citra. Reduksi noise merupakan suatu proses untuk mengurangi noise pada sebuah citra untuk meningkatkan kualitas citra yang merupakan langkah awal dalam citra. Salah satu teknik yang digunakan untuk mereduksi noise adalah filter yang melakukan pemisahan noise dari objek-objek pada citra. Algoritma yang digunakan pada penelitian ini adalah Arithmetik Mean Filter yang melakukan reduksi pada noise dengan cara mengganti nilai piksel dengan nilai tengah (rata-rata) intensitas piksel citra yang mengandung noise. Citra yang terkena noise biasanya mengalami penurunan mutu, kurangnya keindahan citra tersebut. Sehingga sangat diperlukan teknik reduksi noise, karena dengan teknik ini citra yang tadinya mengandung kotoran yang menempel atau bintik-bintik, kini bisa dibersihkan dan citra terlihat lebih indah bagus.]]>

<![CDATA[Text generally contains a series of characters and can form a word, letter and narrative. For example, a text file that is large in size results in the sending process taking longer, and uses a large amount of memory space in its storage. So to save storage space and speed up the process of sending text files, it is necessary to do a compression process so that the text file size becomes smaller. One of the file compression techniques that can compress text files well is file compression using the Tunstall code algorithm. The Tunstall code algorithm work system is to determine the sequence of symbols for each codeword, take the highest probability and iterate as many as N (number of symbols) to be compressed. By using the Tunstall code algorithm, the authors managed to compress a text file quite well, namely compressing the text file size from 80 bits to 40 bits with a compression ratio of 50% reduction in size.]]>

<![CDATA[The use of a database in an application can affect the size of the application itself. The size of the database is influenced by the number of database records, so it requires a compression technique to compress database records in the flora encyclopedia application. Completion is done to reduce or reduce the size of a data so that the data size becomes smaller and with compression makes it easier to transmit. Many algorithms are developed in the compression process, one of which is the arithmetic coding algorithm. Performance measurement of compression results by applying the arithmetic coding algorithm in compressing the flora encyclopedia application database records, namely producing Ratio of compression (2.2), Compression Ratio (45%), and Redundancy (55%).]]>

<![CDATA[With the development of information in this day and age chat plays an important role in all aspects of human life. Where chat as a communication tool that can help communicate without any time restrictions and is free from obstacles. But in communicating through chat applications can not be free or as free in communicating as usual. Where chat has a predetermined number of bits, so that in sending text messages the chat application cannot be at once or in one delivery but in multiple transmissions. Therefore the chat application requires a compression where the text messages to be sent through the chat application do not take a long time and do not send several times. It is enough to send only one text message to those addressed. But sometimes text messaging is not only a problem in many or few text messages to be sent there are other obstacles in sending text messages that must be overcome. Text messages that have been sent to those intended, sometimes the text messages have changed not at its disposal or not the same as what was sent. Therefore the chat application is in need of security on the chat application which can secure text messages to be sent to the intended destination without changing one bit. Chat applications provide solutions to communication problems because they are hampered by distance and time. Chat application provides convenience in communicating chat to several people who have great distances by applying the Rice Codes and Rivest Shamir Adleman (RSA) algorithm to chat applications that are designed using Miscrosoft Visual Basic 2008 programming language as a means of compressing and securing text messages.]]>
