<![CDATA[Hal yang paling penting pada media teknologi saat ini adalah keamanan data atau informasi. Citra digital adalah salah satunya data yang visual yang banyak disalahgunakan oleh pihak yang tidak bertanggungjawab. Oleh karean itu dibutuhkan suatu wadah tempat citra digital tersebut disisipkan agar dapat terhindar dari orang yang akan menyalahgunakan citra tersebut. Seni untuk dapat menyisipkan data atau informasi ke dalam suatu media penampung seperti gambar, video, audio, dan teks adalah teknik steganografi yang akan membuat orang yang melihat atau menerima data atau informasi tidak menyadari ada informasi penting di dalamnya. Oleh karena itu diperlukan perangkat lunak untuk menyisipkan sebuah informasi penting yaitu citra digital ke dalam wadah penampung yaitu file video. Pemilihan file video sebagai wadah penampung dalam penyisipan citra membutuhkan metode yang tepat. Metode yang digunakan dalam proses penyisipan adalah chinese remainder theorem. Meningkatkan keamanan serta kompleksitas komputasi rendah adlah keuntungan dari metode chinese remaninder theorem]]>

<![CDATA[Secara umum, stock opname dilakukan untuk mengetahui secara pasti dan akurat mengenai catatan. Kegiatan ini memang cukup menyita waktu, karena akan memeriksa dan melakukan perhitungan barang yang ada di dalam gudang secara langsung. Sistem stock opname yang saat ini diterapkan PT. Arma Anugerah Abadi masih menggunakan cara manual yaitu dengan melakukan proses penimbangan dan perhitungan dari sisa bahan baku yang dipakai untuk membuat resep bolu dan roti. Data yang didapatkan menjadi tidak akurat dan dapat menyebabkan kerugian bagi perusahaan. Oleh karenanya, diperlukan sebuah metode sistem aplikasi agar perhitungan yang dilakukan menjadi lebih akurat dan terkontrol dengan baik. Metode Min-Max Stock merupakan suatu metode yang digunakan untuk menentukan jumlah persediaan maksimum dan minimum agar tidak terjadi kekurangan dan kelebihan pada data stock opname. Diharapkan dengan diterapkannya Metode Min-Max Stock pada sistem stock opname bahan baku pembuatan resep bolu dan roti dapat memperkecil tingkat redudansi data, stock barang menjadi lebih stabil dan perhitungan yang lebih akurat, agar kinerja karyawan menjadi lebih giat dan semangat sehingga target-target yang ingin dicapai oleh perusahaan dapat dijalankan dengan baik]]>

<![CDATA[Video is a technology for capturing, recording, processing, and rearranging images usually using electronic signals, or digital media. For example, a video file that is large in size causes the sending process to take longer, and uses a large amount of memory space in its storage. Problems that arise due to the large file size include the wasteful storage media used, as well as more time in terms of data exchange, data transfer via the internet is a big problem in Indonesia because download and upload speeds are very low. To overcome this problem, data compression techniques are needed. The concept of compression was born as a real solution to the problem of the amount of space needed to store various digital files, including video files. Compression technique is a technique that compresses files so that their size becomes smaller while maintaining the quality of the representation of the filet.]]>

<![CDATA[Transfer files that have a relatively large size, result in a long transfer process and also consume a large internet quota in the sending process. Where the smaller the file size to be sent, the transfer process is also fast, and does not consume a lot of internet quota. To solve this problem, it is necessary to have compression which functions to reduce the size of the files to be transferred. One of the compression algorithms is H.264. The compression process using the H.264 algorithm is carried out when the file is sent, then when the file is received by the recipient, the file will be decompressed. Using the H.264 algorithm, the file will be sent successfully reducing the file size with a ratio of compression (RC) 2.5%, compression ratio (CR) 40%, redundancy (RD) 60%, and helping the transmission process of sending large files will be faster and save internet quota.]]>

<![CDATA[Korean drama application is an application that is useful as a means of entertainment. When the user downloads the Korean drama application video on a smartphone (cellphone) and saves the video file downloaded by the Korean drama, it will produce a large file size. Because in general we do the activity of downloading many Korean drama videos, we get a long video duration. The longer the video duration, the larger the file size will be. Then the large file size will cause problems because it is limited by storage capacity. When you want to send it, it will take a long time to solve this problem, a solution is obtained by compression. The Elias Gamma Code algorithm is a lossless compression technique, which does not remove previous information, where the decompression results of the compressed video are the same as the original video file. By using the Elias Gamma Code algorithm, the Compression Ratio performance is 36%. These results prove that the compression of the downloaded video files by applying the Elias Gamma Code algorithm can reduce the size of large video files to be smaller than the original size.]]>

<![CDATA[Crossword puzzle is a word game which is usually in the form of a series of empty spaces in the form of black and white squares, the objective of this game is to fill the white boxes with letters, form certain words or phrases, by completing clues that lead to to a specific answer. The type of crossword puzzle game is currently developing, one of which is a cross word crossword puzzle, in this game the collection of letters is random and the user will look for a word from the random letters. However, it is still not known what randomization algorithm was used to make the crossword game application to scramble the letters so that they can become random letters that will be compiled by the user. After seeing some previous research, choosing the Fisher Yates Shuffle Algorithm which is applied using the Visual Basic Application as a solution is considered very appropriate, where this algorithm will initialize letters first to numbers then the initialized letters are randomized using an algorithm, and the user guesses the series of letters that are used has been scrambled before.]]>

<![CDATA[Nowadays we are in the era of the digital world, there are lots of equipment that has a tool for recording photos in the form of a camera on a smartphone. The weakness of smartphones is the small storage space, so users must be good at managing files stored on the smartphone. There are so many applications in smartphones that provide facilities for sharing images. This of course will greatly burden the storage space of the smartphone because it stores image files which are generally large in size, especially if the image files are the same or duplicate, of course it is very burdensome for storage space. It will be very difficult to distinguish an image file without looking at the contents of the image file. So if you want to distinguish one image file from another, the user must see the contents of the image file and this will certainly be very difficult. For that we need a method that can be used to identify the same image file or duplicate image files so that a decision can be made to delete the duplicate document files so as to save storage space. In cryptography there is a hash function which is a one-way function that can generate the identity of a file, where if the image file contains the same content, it will produce the same hash value. It can be used to identify the same or duplicate image files. In the hash function there is the SHA-256 method or the Secure Hash Algorithm 256 which is one of the hashing algorithms that is often used to encrypt data with a length of 256 bits. By applying this algorithm to the file scanner application, the results of the image file search are grouped based on the same hash value and users can make it easier and faster for users to delete duplicate image files without having to open and view the contents of the file.]]>

<![CDATA[Nowadays there are many applications that help the process of duplicating audio, of course this takes up more storage space. For that we need a method that can be used to identify the same or duplicate audio files. The solution that can be done to handle duplication of audio files or duplicates is to apply hash type cryptography techniques where the process of identifying the hash value of the audio file is carried out so that the resulting value is different from the original file. The hash type cryptographic algorithm used is the MD4 algorithm. The results obtained from the process of applying the MD4 algorithm are grouping audio files based on the same hash value, making it easier and faster for users to delete duplicate audio files]]>

<![CDATA[The large Indonesian dictionary has a large size because the quality of the resulting dictionary is better, so the file size needed for it is getting bigger. And the compression process is needed to reduce the file capacity to be smaller in order to save on the use of storage space. With a relatively large data size, during the data transfer process it can fail because the storage media does not have enough space. By performing the compression process on the large Indonesian dictionary, a process can be carried out to reduce the size of the data by reducing the bits in the large Indonesian dictionary, making it easier to carry out a data transfer process effectively. The procedure for compressing the large Indonesian dictionary (KBBI) starts from selecting the large Indonesian dictionary to be compressed, then the book will be compressed with the punctured Elias code algorithm so as to produce a compressed book that has a smaller size.2. The implementation of the punctured Elias code algorithm for compression of the Big Indonesian Dictionary (KBBI) is done by reading the hexadecimal value from a Big Indonesian Dictionary (KBBI), then changing the hex value into a new bit value in the form of a binary number, then rearranging the binary value into new character. Where the compression results are based on the ratio of 32% based on 80 bit data samples with 25 Bit compression results]]>
