Abstract

WAV file is a standard format that is widely used in multimedia and games on various platforms. Ease of access and development of technology with various media making it easier to exchange information to various places. Both important and confidential data need to be kept confidential because of various security threats so that data can be tapped and known by third parties during the submission process. One method of data security is cryptography using a public key algorithm that is poluler is RSA (Rivest Shamir Adleman). From these problems raised the idea to create a data security application whose function can perform data security using RSA algorithm. The programming language used is C # with Visual Studio software, the data being processed is a sample of each byte in a WAV file, the header will be the same as the beginning so that the WAV file can be played even if the information is disguised. RSA algorithms can be implemented into programming languages so that WAV files can be processed and secured data. Although the results of WAV file size after encryption becomes larger depending on the key used by existing information can be disguised properly.

Abstract

    One application of computer technology in the medical world is to determine the ideal body weight (BMI) of a patient by comparing the body weight, height, and size of the patient's own skeleton, so doctors can determine the diet menu that is most suitable for such patients. This becomes very important, especially in the field of medicine, such as the field of beauty, athletes, or other fields that require ideal body shapes such as models, artists and so forth.    This ideal body weighting system is done by the ratio of height to body weight, and the size of the patient's frame. While the K-Means Clustering algorithm is an algorithm that can classify data based on benchmark values given and calculate the data group.    This system can be used to determine ideal body weight by applying BMI values as X coefficients and the patient frame size values as the Y coefficients and cluster central points are set first. However, this system still needs further development because there is no change facility to clustering data category, grouping process is shown in the form of animation, and the need of clustering category in store in one structured database. Keywords: Ideal Weight, K-Means Clustering Algorithm

Abstract

For fishermen, fishing traditionally is a job that takes a long time. The existence of a point where a bunch of fish gather is also difficult to determine if traditional methods are taught which sometimes get an estimate that often misses. This study aims to design a device that serves to catch fish automatically and apply the detection of the presence of fish in a shallow water. By using Atmega8535 microcontroller component, and BASCOM-AVR, fishing can be done easily because it implements tool automation on fish network. Keywords: Algorithm, Fish Catcher, Microcontroller, Atmega8535, BASCOM-AVR

Abstract

Drop-out is a form of failure to follow the students in the educational process at university. The number of students drop out in addition detrimental to the personal / individual, it is also detrimental to higher education institutions themselves. Therefore, it is necessary to study to find the causes or factors that affect student drop-out so it can be useful information for success in higher education. Methods backpropagation artificial neural network is a mathematical model that is used for the identification and classification based training and learning is done. In this study, backpropagation artificial neural network method used in identifying factors - factors causing the drop-out experienced by the students by making learning of the data - the data attributes of students drop out. Backpropagation artificial neural network implementation is done in this study produces good results where backpropagation artificial neural network can produce factors that cause dropouts appropriate to attribute a given student. Keywords: Artificial Intelligence, Artificial Neural Network, Backpropagation

Abstract

In the World of Information Technology computer science, data security something that is very important so that data can not be misused by some parties who have not / not have rights. In the delivery of documents documents is needed a security so that the document file can be accepted by those who have the right to receive it. It is therefore very necessary to process a document encryption / encryption file. Among the science of cryptography that can secure the document file such as LSB Steganography Algorithm (Least Significant Bit). This analysis aims to improve the security of document files by encoding a document file, then providing a password into the document file.Keywords : Encryption, Data Security, LSB Steganography, Files, Documents

Abstract

Facility plays an important role of the real world, the facility is no longer a secondary requirement but becomes a primary need. Provision of facilities from any company requires a competitive location, so that the facilities provided can be useful for others. Dynamic Programming was once used to determine the best opening schedule of Subset as an "optimal" location and relocation strategy for planning. So in this research done determination of location of facility and its relocation with dynamic programming so hopefully can use optimal budget with optimal time.Keywords: Facility Location, Dynamic Programming

Abstract

Playfair Cipher method is one of cryptography method that has long been known and still used until now. But the cryptanalysts are trying to solve the method so it is necessary to modify the Playfair Cipher in order to increase the ability of the security provided. By changing the size of the matrix to 6x6 by adding characters from 0 to 9 and sorting by array into insertion into the matrix, it is expected to be stronger than the standard playfair.
