This is because there are no tests conducted on new students so that the handling of mental retardation student learning is a bit disrupted. Every mentally retarded child has different handling according to their individual abilities. This study aims to apply the modeling of UMI in designing the decision support system application in determining the class of mentally retarded children. UML is an Object Oriented (OO) based modeling concept that can help in system design and analysis. In UML many diagrams can be used to analyze systems and system design. UML has three main categories of diagrams namely structure diagrams, behavior diagrams and interaction diagrams. Where each of these categories has a diagram that explains the system architecture and integrated with each other.

Someone with intellectual barriers has been ensured that he is a person with mental retardation. In general, mentally retarded children are children who have deficiencies in terms of intellectual function in real terms and together with that it also has an impact on deficiencies in terms of adaptive behavior. Children have the right and opportunity to develop according to their potential, especially in the field of education. "Children who have physical or mental disabilities are given equal opportunities and accessibility to get an ordinary / extraordinary education." Handling the learning of mentally retarded children depends on the difficulties experienced by each individual. The role of the teacher in handling this is very important. Teachers as mentors in class need to view mentally retarded students with varying conditions about th...

One application of artificial neural networks is in the field of biology which to categorize plant species. In order to determine the species of a plant, one usually looks at its flowers or its leaves. In this research, two artificial neural networks (ANN) methods which are backpropagation and simple perceptron are applied separately in order to evaluate whether a single leaf. A recognition with leaf images as input data is built. Then, the application will do feature extraction whose result will be trained further with both backpropagation and simple perceptron. This study aimed to compare the accuracy of both methods is the introduction of the leaf image. From testing to the some “jarak” and not “jarak” leaves, the result of recognition on the leaves for the perceptron and the backpropagation method is the same. But the rate of speed for training, the learning rate (α)= 0.2, 0.5 and 1, the perceptron method is faster than the backpropagation method.

This research is based on the transformation of the course process from face-to-face learning to remote learning (PJJ) by relying on technology as a substitute for learning media, known as distance learning and online learning. This research was conducted using case study methods. This research was conducted on informatics engineering students in multimedia courses. Sampling techniques using purposive sampling methods. The results showed that the application of LMS-Google Classroom to online learning for Informatics Engineering students during the COVID-19 pandemic had a positive effect, especially in terms of absorption related to understanding lecture m...

Therefore, a security system that can protect data that is considered important by encrypting the data, and create a secret key to be able to open the data that is difficult to be detected by unauthorized parties. This study aims to establish a security system by using a cryptographic algorithm called Bit Inserted Carrier (BIC) where the basic concept of the BIC algorithm is to load bits of plain data into a file mixed with fake or noise data, protected by password or keys. The generation of false data (noise) and position placement settings of these bits are determined by a Pseudorandom Number Generator (PRNG) mechanism. Stages that the authors do to perform the process of forming the application include the stages of problem analysis, application design involving data flow diagrams, algorithms and flowcharts along with modeling the program structure and interface design applications, so that the application formed to be easy to use and has the optimal function. To ensure that all functions contained in the application system BIC algorithm work optimally, then the application system is tested and formed final conclusions. The built application only works to perform the encryption and decryption process and can not prevent outsiders from deleting the data. You should try not to use the same key to encrypt different files.

Here the role of both parents in the process of growth and development of children is very necessary in order to monitor every change that occurs. But sometimes parents experience problems or because there is no accurate record of toddler growth and development, so the observation of development is not optimal. With the current technological advances that are increasingly rapid with the many uses of Android mobile devices can make a way to develop an application that is able to facilitate parents in observing their toddler growth. Therefore researchers designed and made an application for information systems development of toddlers with the aim to support and facilitate parents in observing the process of developing toddlers and make it easier for parents to get knowledge about health in infants. The development of this information system uses the waterfall method. The method begins with analysis, design, coding and then testing the application. Application testing is done using the blackbox test and the test results show that the process in the system has run smoothly. User test is done by giving questionnaires to prospective users and the results show that the user agrees and argues that this information system is useful for parents in observing the growth of toddlers. Respondents of users agree that the Android-based Toddler Development Information system can be used as one of the media to find information about toddler health and can be used to record the progress of toddlers.

The number of restaurants makes many consumers confused to choose the best restaurant. this study explains how to determine the best restaurant. Many aspects must be in value to determine the best restaurant based on consumer ratings. in this study the criteria assessed were food, place, price and service. The criteria assessment process is based on interviews to consumers who have visited the restaurant. The value given by the consumer is then calculated using the manual process and then compared with the AHP method. AHP (Analityc Hierarchy Process) is one of the methods of decision making. AHP is a practical method for solving complex problems. In this study, the author has managed to get the best restaurant results. However, research criteria and methods can be developed for further study.

This research was conducted in the Department of Information Systems involving 30 students of the semester of the academic year 2014 / 2015. Research consists of 2 cycles of action. Student learning result data is collected using test and study contract. Student learning independence and student responses were collected by questionnaire Self Directed Learning Readiness (SDLR) that has been modified to determine the self-learning readiness picture and can manage learning strategies in conducting the learning process [20]. Data were analyzed descriptively. The results showed that there is an increase in learning outcomes and student learning independence after applied self-directed learning model. In addition, the results of the study also show the students’ positive response to the implementation of ...

While an Illustration is an art of visual on writing artwork, drawing, painting, photography or another type on an art. Most People want to be an illustrator usually must learning their skill basic with self-taught or learning on art of school. However most people specifically for known illustration and want to learn their skill on art school but constrained with distance or time or another reason with their tools art. Until the most people can not got their skill with fast. By looking at this times with the Design Online Learning Of Education On Illustration At Website, which have contain more information and education about illustration and the illustrator can make easier for other to learning or to hone their skill with complete material which is came from most experience illustrator. The design will become a place of sharing content about illustration, it was built with PHP, and DBMS MySql. This research resulted...
