Different types of plants make identification difficult. Therefore, we need a system that can identify the similarity of the leaves based on a reference leaf. Extraction can be done by taking one part of the plant and the most easily obtained part is the leaf part. Natural objects such as leaves have irregular shapes and are difficult to measure, but this can be overcome by using fractal dimensions. In this research, image detection of plant leaves will be carried out using the box counting method. The box counting method is a method of calculating fractal dimensions by dividing images into small boxes in various sizes. Image detection using fractal dimension values, we know which leaves the match with the reference. In this study,10 species of leave were tested, with each species 10 samples of plant leaves. Image testing of plant leaves uses a variety of r box size, namely 1/2 ,1/4 , 1/8 , 1/16 ,1/32 , 1/64 , 128which obtain an average match accuracy of 44%. Keywords: Box Counting, Fractal dimension

Cryptography is knowledge of encoding data to ensure the confidentiality, security, validity and integrity of data. Cryptography is divided into two namely classical cryptography and modern cryptography. One example of modern cryptography is the Electronic Code Book (ECB). Electronic Code Book (ECB) is a modern cryptographic method used to encrypt and decrypt text, images and more. The image is formed from several pixels which consist of several bits in a pixel. Bits are divided into two namely Least Significant Bit (LSB) and Most Significant Bit (MSB).LSB is the four rightmost bits while MSB is the leftmost four bits of a pixel. The purpose of this study is to compare the level of security of Electronic Code Book (ECB) image security results with the results of securing an Electronic Code Book (ECB) modified image. The data used in this study are 8 RGB and Greyscale images also a key in the form of one ASCII character. The results obtained show that securing images with modified Electronic Code Book (ECB) is safer than securing images with Electronic Code Book (ECB) based on histogram analysis, differential analysis and correlation coefficients. Keywords: ASCII, Electronic Code Book (ECB), Most Significant Bit (MSB)

Communication in the current era of globalization is very developed. Many applications that can be used to facilitate communication. However, because of this convenience, the security of the information contained in it will be more easily hacked by irresponsible people. Cryptography is the science or art for security message. In cryptography there are two important processes, namely encryption and decryption. The sender's job is to encrypt the message and the receiver's job is to decrypt the message. The key used for this cryptographic process is the Cipher Block Chaining (CBC) operation mode. CBC mode is a very simple operation mode, so additional techniques are needed to make it more secure. The plaintext will be replaced with new plaintext resulting from a combination of Caesar Cipher and Reverse Cipher techniques. The results obtained indicate that the application of plaintext modifications to CBC can improve message security because the keys used are increasingly complex.

Abstract. Decagonal Penrose Mosaic is a decagonal interior design constructed by applying the basic of golden triangle Penrose tile. There are several techniques to design the mosaic, some of them are as follows: (1) constructing Penrose tile on the fifth iterations constructed from isosceles triangles which on each triangle is defined by decagon sector; (2) stating Penrose symmetry base as the mosaic design base; (3) dividing each Penrose tile golden triangle into 3 zone; (4) stating Penrose symmetry base to fill in Penrose tile golden triangle in each zone; (5) coloring the interior Penrose symmetry base and the backgrounds. The formed design has been found several Penrose mosaic models in full symmetry, not fully symmetry, similar and overlap, which each models has natural motive and symmetry characteristics. By using the different coloring techniques it has been formed some coloring pattern on the centre, homogenous distribution, or spreading. This would enrich the varieties of mosaic design forms. Key Words : decagonal golden triangle Penrose tile, Penrose mosaic

Data security is very important data needed to stay awake in strict confidence from hacker intrusion or criminals who want to steal the data. Data security methods that are used in this paper is a digital image encryption by using a modified Hill’s code which is done by changing the way of encryption. If we are using Hill’s code then matrix pixel multiplied is the key matrix while on the modification Hill’s code before the key matrix then the matrix is multiplied pixels must be added to the results of the main diagonal elements of the matrix times key. The results obtained in the process of digital image encoding indicating that the image is encoded with password modification results of modified Hill's code more mixed reviews when compared to the image that was encoded with password Hill so that more effective in securing data in the form of a digital image. The size of the image file using the encoding results in a modification password Hill is smaller than ordinary password Hill with a percentage decrease of 4.6 % so more ease in delivery through electronic media Keyword: Digital image, modified Hill code, encryption, description

Data security is a very important thing to do so that messages or information are sent to someone who is not known by unauthorized persons. Data security techniques that The ones that are often used today are cryptography and steganography. In this study, the data is to be secured in text. To increase security, text messages are first encrypted using the vigenere algorithm and column transposition. This text message is then hidden into an image (cover image). The encrypted text message was hidden in the image using the LSB algorithm and column transposition. The results of the study show that the virtual stego image generated is very effective similar to the original image. Based on the results of the MSE and PSNR analysis, it can be seen that the resulting image quality can be categorized as good. This can be seen from the PSNR value above 50 dB and some even above 60 dB. Based on the results of the LSB analysis, the stego image does not look strange so it will not be suspected by unauthorized people that there is a hidden message in the image.

This paper proposes a new encryption method for the encryption of medical images. The method is used to divide the image into several blocks and then scramble the image blocks using DNA chains and then shift the pixels in a circle with certain rules. To provide a more secure result, the input key contains a DNA chain and is equipped with complementary rules, and is converted into a hexadecimal number using a DNA coding table. Experimental results and values of NPCR and UACI show that the scheme achieves good encryption and decryption results.
