<![CDATA[Edge detection is the first step to cover information in the image. The edges characterize the boundaries of objects and therefore edges are useful for the process of segmentation and identification in the image. The purpose of edge detection is to increase the appearance of the boundary line of the object in the image. The sobel method is a method that uses two kernels measuring 3x3 pixels for gradient calculations so that the estimate gradient is right in the middle of the window. Digital image processing aims to manipulate image data and analyze an image with the help of a computer. Matlab is made to facilitate the use of two collections of subroutines in the fortran library, linpack and eispack, in handling matrix computing, and develops into an interactive system as a programming language. Experimental results from the input image research, namely the flower image have different MSE values because each input image has a different pixel value]]>

<![CDATA[Learning process should be an interesting process, especially for kids in elementary school. There are many methods has delivered to make the kids going fun to learn any new thing. Information and Communication Technolgy (ICT) could been involved to the learning process. ICT-based learning tools that used to help teachers and parents are developed in this research. Astronomy is one of the fields of science which is generally taught in schools as a part of natural science subject. In this study, authors developed an astronomy learning application’s named Belajar Astronomi that comes as a supplement study material for elementary students. This Astronomy Learning application is designed to be a tool for students to study astronomy independently. Belajar Astronomi’s application developed with the Visual Basic programming language in Microsoft Visual Studio 2010 using Waterfall methods, to make sure Its functionality and usefulness. The application is equipped with images, text, and videos that can help students to learn astronomy more easily, Its also equipped with quizzes as training materials that can help students in sharpening their knowledge in Astronomy subject.]]>

<![CDATA[In general, the habit of learning a person is influenced by personality variables. Not a few parents who do not understand about the method of effective learning for children, the parents and teachers must approach first in order to know the personality and habits of children, especially children with a tunagrahita. Learning method given to the child is very important, therefore teaching methods applied by parents at home and given by teachers should be the same in order to facilitate the child in understanding the lesson and not experiencing confusion because accept different learning methods. This is very influential, because there are still many students with disabilities who still have difficulty understanding the learning especially reading, writing and counting where the learning will be very influential for the community. Based on these problems it is necessary expert system to facilitate parents in providing home study in accordance with the methods of learning provided by teachers at school so that students more easily and quickly in understanding the lesson]]>

<![CDATA[Sundanese are tribes from West Java and Banten that use their own local language known as Sundanese. The large number of local residents who still use Sundanese in communicating daily is an obstacle in increasing tourist visits to the area. Then a translator is needed which can be used as a liaison between tourists and local residents so that there is no miscommunication between the two. But the increasing number of tourists, there is a lack of the number of translators needed, so it needs to be made a translator application by utilizing the development of computer technology. The application developed is an Indonesian-Sundanese to translate in the form of words using the IDA* algorithm. This algorithm is an A* algorithm whose depth is limited to each search iteration. Although the time complexity is higher than that of the A* algorithm, the IDA* algorithm does not require as much memory as needed by the A* algorithm. Then the IDA* algorithm is used in this study. The results of this study indicate that the IDA* algorithm can be implemented to convert translate words in Indonesian and Sundanese based on the estimation value of the smallest total cost of each word stored in the database, where the word that has the smallest total cost estimationcan be selected as a result of the translation.]]>

<![CDATA[Diabetes Mellitus Diagnosis Expert System with Web-Based Forward Chaining Method. An expert system is one branch of artificial intelligence technology that combines the knowledge of an expert with tracing data to solve problems that are normally carried out by an expert. The development of information technology now makes it possible to access information from anywhere and anytime. So the role of information technology is increasingly useful to be able to develop in various fields including in the health sector. One of them is the system used to diagnose diabetes mellitus. Diabetes Mellitus is one of the most common diseases in the world. The inability of the pancreas to produce insulin normally becomes one of the reasons a person has this disease. In this research, the method used is Forward Chaining which sorts all data obtained before getting the final conclusion. The final results obtained from this study is an expert system application for diagnosing diabetes with a forward chaining method, where the user answers questions based on perceived symptoms, then the results obtained in the form of disease and explanation of the disease.]]>

<![CDATA[Education about religious sciences, especially hijaiyah letters is very important as a provision to be understood by humans as the basis of their lives to face life in the future. The difficulties experienced are quite reasonable, because the Al-Qur'an uses Arabic. Learning with the Koran system is usually done in a relatively long time even sometimes for years. This is not effective and efficient in teaching and learning activities. So with the presence of a new learning media to utilize computer technology, it is expected to be developed into an interesting learning for kindergarten children. Therefore, the authors make interactive animated hijiayah letter recognition so that with interactive application of the introduction to hijaiyah letters for early childhood at Al-Hidayah Kindergarten Bekasi is very helpful in teaching and learning process to be more fun and effective so students are no longer bored in learning and attracted the interest of students to a better understand on how to read good and correct hijaiyah letters. As well as helping teachers to innovate in learning process because with this interactive animation application the instructors become easier to deliver material about the prayer movements to students.]]>

<![CDATA[— Seal Chamber in Mechanical Seal Test Plant is a part that is used for heat exchange between hot liquid fluid in the form of condensed steam and cold liquid fluid in mechanical seal test plant. In heat exchange it is arranged so that the hot fluid can raise and lower the temperature from 20 ℃ to 80 ℃ and vice versa within 1-2 minutes. In the exchange of heat, data acquisition is still needed, which is then processed by data acquisition software that has been calibrated to determine the sensor response to the environment for test plant. In this study, data acquisition and monitoring systems were carried out and multi tasking synchronization with several sensors with one centralized controller. In addition, the volume seal chamber is equipped with a valve regulated by a servo motor to regulate the amount of hot liquid fluid in the form of condensed steam. Valve is used to be a regulator of the flow of hot fluid that enters and exits the seal chamber volume model. This research will be used to control the level and temperature in prototype of the Mechanical Sil test plant according to API 682. The manual control is done and there is an average error for the relationship of the actual valve with the water flow sensor of 8.42%.]]>
