Abstract

Most of Safes lock system is still using conventional methods nowadays. The conventional method leads to the safes’ burglary. Some of the causes are the safes’ code that can be tracked easily and the key can be duplicated. Previous research on safes’ security has ever been done. The weakness of the study is there is no security system using cryptographic algorithms for data security. The development of a safes security system by implementing ElGamal algorithms is done by following the engineering approach with the stages of methods analysis and design system, implementation and testing of the analysis and the discussion of the overall system. In the analysis and design of mathematical models using ElGamal algorithms, uses fast powering theorems and applications design uses Object OrientedProgramming. In the analysis of hardware refers to the datasheet and calculation of the value of electrical characteristics of the circuit. In the safes lock system, the outcome of the research is a safes prototype which is equipped with enhancements that include a series of processing algorithms, the data viewer, a wireless data transfer device, the Android smartphone as a system of user authorization. For the lock safes systems is using a locked solenoid. The control system is done by a lock safes android smartphone via Bluetooth communication. The test results also indicate the system will open the safes if the code and the public key is entered correctly, and the system will not open if one of the codes or the public-keys are wrong or both are wrong.

Abstract

Image processing can proces many colors in the fruit, especially in fruit of chili. There are several colors contained in the chili fruit that is green, orange and red. Chilies are not predictable price because the chili have fluctuate prices, the chili can be determined is only the quality. The main parameters of this research are chili size and color of the chili, because these fitures can be processed to get output, namely the prediction of the chili quality. Some processes be used to predict the chili. These processes are extraction of color RGB, LAB conversion of to RGB and Grayscale, level adjustment, color Region. Some of these processes do to get a percentage of the stalk (after being separated by body of the chili) and percentage of the maturity. The last proces is classifying the chili that have been obtained percentage of stalk and maturity then using Naive Buyes Classifier metod for classifying to four kind fo quality, namely quality A, B, C and D. These qualities classification are A : consists of red chilies or ripe chili that has big size, B : consists of measuring big green chili, C : consists of small pieces of red chili and D : comprises small green chili.

Abstract

Grouping of tomato maturity level is one way to pay attention to the quality of the tomatoes. The traditional way takes a long time and low accuracy, since the determination of the level of subjectively assessed. In addition, the importance of the classification of the level of maturity of tomatoes due to a period of tomato maturation process is relatively quick, so it can reduce the risk of rotting tomatoes. The dataset used in this study was 108 tomato image taken using three types of smartphones. The dataset is divided into 66 training data and testing the data 42. Improvements to the image preprocessing stage is done with adaptive histogram equalization and compared with the histogram equalization. In the feature extraction using color features of the R, G, and A *. The classification of the level of maturity of tomato is done by comparing the accuracy of using multi-SVM and KNN. In the Multi-SVM method using the highest percentage of kernel functions RBG is equal to 77.84%. While the method kNN highest percentage was 77.79% using a value of k = 3.

Abstract

Artificial AlgaeAlgorithm (AAA) is an optimization algorithm that has advantages of swarm algorithm model and evolution model. AAA consists of three phases of helical movement phase, reproduction, and adaptation. Helical movement is a three-dimensional movement with the direction of x, y, and z which is very influential in the rate of convergence and diversity of solutions. Helical motion optimization aims to increase the convergence rate by moving the algae to the best colony in the population. Algae Algorithm Optimization (AAA ') was tested with 25 objective functions of CEC'05 and implemented in case of pressure vessel design optimization. The results of the CEC'05 function test show that there is an increase in convergence rate at AAA ', but at worst condition of AAA' becomes less stable and trapped in local optima. The complexity analysis shows that AAA has the complexity of O (M3N2O) and AAA 'has the complexity of O (M2N2O) with M is the number of colonies, N is the number of algae individuals, and O is the maximum of the evaluation function. The results of the implementation of pressure vessel design optimization show that AAA's execution time increased 1,103 times faster than AAA. The increase in speed is due to the tournament selection process in AAA performed before the helical motion, whereas in AAA 'is done if the solution after movement is no better than before. At its best, AAA 'found a solution 4.5921 times faster than AAA. At worst, AAA 'stuck on local optima because helical movement is too focused on global best that is not necessarily global optima.
