<![CDATA[Population data is information about the existence of someone in a country. The data can be accepted as validity through management in one of the government agencies. The issue of security and confidentiality of the data is something that is very important because it concerns the identity of a person, in order to avoid theft and manipulation of data it is necessary to apply a data security system. Cryptography is the study of mathematical techniques related to aspects of data and information security such as data validity, integrity, and data authentication. The Advanced Encryption Standard (AES) is one method used in data / information safeguards. The implementation of the AES algorithm in securing population data of the Population and Civil Registration Service shows that the method can produce messages that cannot be read or understood by humans (encryption) and produce the same message as the initial plaintext that was imputed (decryption)]]>

<![CDATA[Scheduling is one of the important stages in the industrial world, especially in terms of building a building. Usually in handling a development project, resources are available in a limited amount of resources. The purpose of project scheduling is to optimize project scheduling with the Harmony Search method. Harmony Search method is a method that adopts the process of finding a blend of tones in order to obtain beautiful musical harmony. Similarly, the optimization process that looks for optimal or perfect solutions based on functions and objectives. Harmony Search (HS) was first introduced by Zong Woo Geem in 2001. The basic idea of Harmony Search is to mimic the process of improving the harmony of music undertaken by music choir groups. When a music choir makes improvements to the harmony of the music being played, there will be three possible choices, including playing well-known harmony music based on their memories, playing harmony music that is similar to well-known harmony music but there is little adjustment, or making harmony music that is new.]]>

<![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.]]>

<![CDATA[Database records in the form of text are very widely used, so it is very vulnerable to data theft by unauthorized parties. In order to maintain the security of database records, it can be done by using cryptographic techniques. Cryptographic techniques can encode database records by encrypting them in the form of passwords that are not understood. The Camellia algorithm is one algorithm that can be relied upon to realize cryptographic techniques. This symmetry algorithm will produce a higher level of security against the database record because it can encode it into a password with a fairly complex process that will make it difficult for cryptanalysts to access the database. This research will use the 128 bit Camellia algorithm for the encryption and decryption process, so that in the process it is necessary to go through several long steps in order to produce the final cipher. This algorithm requires 18 rounds where every six rounds must enter Function F and Function FL-1 and also require as many as 26 subkeys, namely kw, k and kl. This study describes the process of securing a database record by encoding it based on the Camellia algorithm, so that it produces a text record database in the form of a password that is difficult for others to understand and understand. This is done in an effort to minimize acts of misuse of database records.]]>

<![CDATA[In the process of capturing images using a camera or other sensors often experience problems and deterioration in quality, such as capture results that are not as expected. This can happen because of the possibility of a camera lens that is not focused, the lighting settings are not perfect, the presence of dust or other dirt on the camera lens. Improving the quality of an image is necessary so that someone can observe the image clearly and in detail without any disturbance bilateral filter method is a filter that functions to replace The value of a pixel with the convolution calculation results in the area covered by the filter, this convolution operation is often involved in neighboring pixel operations. Which then produces software applications that are able to reduce the effects of disturbing noise on digital images with the bilateral filter method. With this method, it is expected to be able to solve the problem of image quality improvement in image improvement applications. This study discusses that the process undertaken to implement image improvement based on the bilateral filter method, then an application is built using MATLAB 2013 as an editor to edit programs.]]>

<![CDATA[Since the discovery of a tool to capture an image (image) in the form of a camera making technological developments not only focus on the tools but also must focus on where the data is stored. The need for storage media is something that is needed in every communication tool. Data and information communication systems are not only in the form of text but can also be in the form of images, videos and audio. Image file size that is relatively larger compared to text files is one of the causes of the amount of memory used for storing image files. The size of the image file can also cause the length of time to send the image file. Image file compression process is one way that can be done to overcome the problem of image file size. Image compression is an attempt to minimize the file size or bytes of a graphic file without reducing the quality of existing images. A certain amount of storage, such as disk space or memory, makes it possible to reduce the image file size. Many algorithms that can be used to compress image file sizes include the ternary comma code algorithm that can help reduce image file sizes. The ternary comma code algorithm has a faster time space compared to other algorithms.]]>
