Abstract

Data is a collection of facts that can be in the form of numbers, symbols or writing obtained through an object. Data can be confidential and can also be public which means that it can be published. Confidential data is data that is not made to be published, but for private circles, because the data is data related to the company or its personal data. However, sometimes confidential data is often blamed for use by other people or third parties by taking or stealing the data for their personal interests and bringing down other people or companies. Given the rapidly developing technology today, it is possible for everyone to create a new technology to manipulate or steal confidential data. To overcome this problem, it is necessary to create data security, so that confidential data owned by a person or company cannot be taken or misused. The data security technique used to overcome this problem is the steganography technique. PVD is an insertion method that works by finding the two closest value differences. The difference is then used to determine the amount of data that can be inserted based on the selected data range. By utilizing this method, an application can be designed that can be used to secure data, especially in the insertion of messages into pdf document files.

Abstract

Confidentiality and security of data is of paramount importance in data communication, both for the purpose of shared security, and for individual privacy. Computer users who want their data not to be known by unauthorized parties always try to find ways to secure the information to be communicated or to be stored. Protection of data confidentiality is increasing, one way is by applying the science of cryptography. Cryptography is one of the sciences used to maintain the confidentiality and security of data that has been developing since ancient Greece. Cryptography is growing from the cruel era to the present. One of the cryptographic methods that is quite reliable, stable and is the parent of the popular cryptographic algorithms today is Cipher Block Chaining (CBC). Cipher Block Chaining (CBC), this mode is a feedback mechanism on a block, and in this case the results of the previous block encryption are fed back into the current block encryption. The trick, the current plaintext block is XORed first with the previously encrypted ciphertext block, then the XOR results are entered into the encryption function. With the Cipher Block Chaining (CBC) algorithm, each ciphertext block depends not only on its plaintext block but also on all previous plaintext blocks.

Abstract

The video file size is quite large where the better the video file quality and the longer the video file time, the file size is quite large in storing the file. With the video file size which greatly affects the length of time the video file is sent. The solution to this problem is to compress the video file. There are many algorithms in video file compression, for example the elias omega code algorithm, elias delta code, stout code, punctured elias code and many other compression algorithms. So with so many algorithms, it is necessary to test several compression algorithms or algorithm comparisons. Algorithm comparison aims to find out which algorithm is more accurate in carrying out the data compression process. The algorithms that will be compared are elias omega code and elias delta code. While the comparison parameters of the two algorithms are the compression ratio and space saving.

Abstract

So far, production has been carried out based on warehouse stock. Where production continues regardless of sales demand. This can result in losses if the number of sales requests is less than the production results so that there are unsold products left, or if there are sales requests that exceed stock so that PT. Satwa Karya Prima was unable to fulfill the request. This is due to the inaccuracy of sales requisition data due to manual recording. To overcome this problem, a new system is needed to improve the current system. From the test results, the software created is able to find out the amount of stock required, the estimated number of sales requests, forecasting results using the Simple Exponential Smoothing and Winter's methods of production each month and production results. It is hoped that using the Simple Exponential Smoothing and Winters Methods can overcome smaller production estimation errors with minimum error values.

Abstract

The procedure for recruiting PAUD teachers at the Bharlind School Medan Foundation is still done manually. As a result, the Bharlind School Medan Foundation spent a lot of time determining the results of PAUD teacher recruitment, recruitment data management was less secure, and the level of accuracy of decision making was less reliable. Because of this, the authors built a computerized decision support system for the recruitment of PAUD teachers for the Bharlind School Medan Foundation. The decision support system method applied in this decision support system is the Multi Attribute Rating Technique Exploiting Rank method. The research method used by the author for data collection in this study is the observation method. The expected results of the research are to make it easier for the Bharlind School Medan Foundation to make decisions to determine the results of PAUD Teacher Recruitment.
