Sriwijaya State Polytechnic Joint Government and Private Parties have had the scholarship program to students who beprestasi and can not afford. Therefore scholarship should be awarded to eligible recipients and deserve to get it. However, in the selection of the scholarship will certainly experience difficulties because of the large number of scholarship applicants and the criteria used to determine the grantee's decision as expected and acceptance of the scholarship has a maximum limit of quotas. It required a study that aims to take into account all criteria decision support to help accelerate and simplify the decision making process. In the selection of the scholarship recipients to take a little longer and less efficient. Besides it takes a long time in the electoral process and the establishment of scholarships also there are opportunities to make the wrong decisions because the process is subjectivity. Therefore made a decision support system that can perform calculations on all the criteria for the selection of scholarship recipients at State Polytechnic of Sriwijaya. The method used in the decision making is the scholarship selection Tsukamoto fuzzy logic method, this method selected because it is able to select the best alternative from a number of alternatives, in this case the alternative meant that students are eligible to receive scholarships based on certain criteria.Keywords: DSS, Fuzzy Logic, Tsukamoto, Scholarships

Steganography and cryptography are security method of secret message from third party who curious to see it. Steganography secures the message by hiding it on digital media. While for cryptography, it secures the message by coding it so the message will be understandable only by the message sender and the receiver. In this research, the secret text message shall be encrypted first by using MARS cryptography algorithm, then it’ll be embedded on bitmap extended grayscale image digital media with adaptive steganography method. Adaptive steganography method consisted of three phases: capacity assessment, minimum error replacement (MER) and false contouring. While MARS cryptography algorithm also has three phases: forward mixing, cryptographic core and backward mixing. After being implemented into the program, the resulted stego-images were assessed subjectively by sharing questionnaires, where out of 33 respondents 72% said that before and after embedded, the images don’t have any differences from its brightness, 48% from its noise, and 67% couldn’t choose which one stego-image is. The objective assessment was done by calculating the value of Root Mean Square Error (RMSE) and Peak Signal to Noise Rational (PSNR), where out of 8 tested stego-images had low RMSE and the PSNR were above 30dB. From both assessment, it’s concluded that the resulted stego-images had good quality (no changement significantly). Keywords : Cryptography, Steganography, MARS algorithm, adaptive method

Private colleges as a form of business engaged in the education course are expected to have good management to knowledge. How knowledge is captured, documented, processed, shared and reused as a knowledge management process is a key business process at a private college. Surely a company can survive and thrive when the business processes running smoothly. It is the basis of this paper was compiled. By identifying the factors that influence the adoption of knowledge management in organizations, this paper tries to develop these factors into an indicator Builder knowledge management framework for private colleges through a literature review. The knowledge management framework is expected to be used as a reference that helps private-college readiness as a strategy the application of knowledge management in the company as one of the effort to avoid the failure of adoption. Key words:Knowledege management, private framework, KM

Image processing has been commonly used in automatic object identification. These are some methods that can be used for automatic object identification, such as LVQ, K-NN, SVM, and Neural Network. This research specifically bring out the topic about the level accuracy comparison in identification of pear variety using grayscale, HSV, and L*a*b* images in aim to get the best image type for pear image identification using neural network. The feature are gray level co-occurrence matrix feature (energy, entropy, homogeneity, and contrast) from canny edge detection’s image and also color feature. Based on image examination result, grayscale reached its best accuracy for 90% on MSE 1e-10 with 10 hidden layer neurons, HSV reached its best accuracy for 100% on MSE 1e-5 with 20 hidden layer neurons, L*a*b* reached its best accuracy for 100% on MSE 1e-5 with 15 hidden layer neurons. HSV and L*a*b* give the better accuracy for pear variety image identification than grayscale.Keyword:Image Processing, Pear, Neural Network, Identification, Gray Level Co-occurrence Matrix, Canny, Color.

Global technological progress requires English as a second language to be learned after Indonesian. Introduces English to children from an early age will facilitate the process of adapting itself to the advancement of information technology which requires knowledge of the English language in the future. Introduce English language in early childhood is not easy, at this time the child is more likely to want to play than the study. The most appropriate way to introduce English to young children is through an interactive game with the look and sound that contain words, numbers, and objects in the English language. Research took the example of the introduction of English language in early childhood in TAMAN KANAK-KANAK ANNISA. Recognition method used was still manually, use English textbooks and teaching aids in the form of images and text. Methods of data collection research are done by direct observation to study sites and interviews to the principal, teachers, and parents. Educational game application designed and constructed using analysis method waterfall, as well as applied to the smartphone and tablet android devices. The research concludes that very educational game to help teachers and parents as teaching media to introduce the English language. Results of the study suggest that applications can be continuously developed to achieve better results.Key words : Educational Game, English Language, Learning

The use of the internet has boost up the interaction of the data and information. The internet has made the transfer of information become faster and reliable. However, there are many malicious applications which consider would violate the information. Therefore, there is a need for a network security to make sure the security on the internet. Network security has three main goals, namely confidentiality, integrity and availability. There are several techniques of an encryption, they are symmetric and asymmetric encryption. In symmetric encryption the key used to encrypt and decrypt a message is similar, while the key used in asymmetric encryption is different. There are many encryption types which are used in today life for example DES (Data encryption Standard), Triple DES and RSA. In this paper an application of encryption will be created. It will be created using PHP programming language and several stages of encryption for instance calculating the hash value using SHA-1, encrypt Hash value using RSA. Finally, the decryption process will be explored to make the encrypted message readable to the user.Keyword: Encryption, RSA, SHA-, Hash.

Game has been the one thing that is in our daily lives. Formerly only used as a means of entertainment games alone, but now the game has become wide functions, such as games can be used as a learning tool, a business area, and competed as one of the sport by professionals. Game development platform can also be viewed directly by the public, at first only games played on computer and console but has now entered the era of mobile game android and Windows Phone. A distinct advantage is the portability of mobile game play, that player can play games anywhere they want as long as they have mobile devices capable of running mobile games.Game developed a modification of the traditional game smack ingkling aimed at children aged 6-13 years , This game has 3 levels where each level the player will be given about the question. The design of this game uses the android operating system. In addition, this game was built using a programming language actionscrpit contained in Adobe Flash CS6. In the development of this game using MDLC (Multimedia Development Life Cycle) with five stages that have been made that concept, design, material colecting, assembly, and testing. Design and manufacture of this game is aimed at preserving the traditional game smack ingkling to be a trend back in the era of smartphones today.Keywords: Traditional games, hopscotch, MDLC, Android.
