Abstract:
Reterdated mental children are children who have an intellectual level below the average. mentally retarded children are children who have intellectual deficiencies or limitations, are below the normal average, so have difficulties in academic, communication, and social tasks, and require special education services. Expert system is one part of artificial intelligence which has recently experienced very rapid development. This study aims to help the Dharma Wanita Extraordinary School to place students and students into a class with groups that are equally backward by applying the K-Means algorithm. The design of this expert system uses Data Flow Diagrams (DFD) and the programming language used to build expert systems in this study is Visual Basic. The results of the expert system built in this study help in diagnosing the level of mental reterdation based on the symptoms given by the user and the level of mental reterdation based on possible values ​​using the K-Means algorithm calculation. Keywords:Expert System, Mental Retarded Children, K-Means Algorithm.

Abstract:
Universal Computer is a business entity in Pekanbaru engaged in the assembly and sale of computers and equipment that do not have a system that integrates well between sales, purchases, and inventory. The recording process is still manual by using the ledger so that the resulting data is less effective and efficient. In addition, the Universal Computer Shop has a weakness in reporting sales, purchases, and inventory that the level of accuracy is still lacking. Entities such as Universal Computer Store will be very good if they have a good information system so that the management of sales, purchases, and inventory in the business will be better. This information system is based on desktop using visual basic programming language .Net and SQL Server 2008 database and information system design that used is Data Flow Diagram (DFD) and ER diagram for business process to be designed. Information systems are provided for Universal Computer Stores to provide convenience to system users, especially employees, suppliers, customers, inventory, goods, and sales, purchasing, sales, inventory, employees, suppliers and customers. It can be concluded that this application is able to assist the Universal Computer Shop in handling the problem of recording purchases, sales, management, inventory, employees, suppliers, customers making reports on purchases, sales, inventory, employees, suppliers, and customers. Keywords: Purchase, Sales, Inventory, Visual Basic. Net, SQL Server 2008

Abstract:
Toko Cahaya Sunnah is a business that produces and sells syar'i clothing. In its business development, Toko Cahaya Sunnah keep trying to expand its market target to out of town even all of Indonesia. To achieve its goal, Toko Cahaya Sunnah requires website. Currently in Toko Cahaya Sunnah in making sales report is still manual using excel application so that data processing of sales report still running slow and not yet detailed. Currently Toko Cahaya Sunnah does not have any special activities or strategies that handle marketing, product marketing is done in a conventional manner by providing customers with information about places, features and products to other potential customers. Ineffective information dissemination prevents customers from knowing the latest information in the Sunnah Light Store thus affecting customers to switch to other stores. With the website using the method of Customer Relationship Management (CRM) then the data storage process can be more accurate and stored neatly and making sales reports will be fast and timely and delivery of promotional information will be faster and response to sales will be faster.

Abstract:
Economics mathematics courses are abstract and require high thinking activities. Nevertheless, all students studying in the Islamic Economics study program FEBI IAIN Bengkulu must learn it because it is one of the compulsory subjects in the Islamic Economics program FEBI IAIN Bengkulu that must be taken. Learning mathematics economics needs to need learning media that can improve students' understanding in learning economic mathematics. With the media, students are given the ease of visualization of the material presented, including series, linear functions and things needed in economic mathematics learning. accurate for users so that they can be used as a choice of learning media in teaching and learning processes, inspire lecturers to use web media in the teaching and learning process and students can study anywhere without being limited by space and time. The method used is research and development or in English Research and Development is a research method that is used to produce certain products, and test the effectiveness of these products used in this study is the software used in this application is moodle, xampp and internet. Keywords : moodle, xampp, internet.

Abstract:
On research done previously for segmentation of vehicle license plates have been on test cobakan method using edge detection to get the edges of characters not quite optimal. Then from the problem on this research will be focused on the detection plates two-wheeled vehicle uses a method of edge detection, where the results of this research will be resized using the technique of measurement of the confusion matrix. where in these measurements will be compared from the entire technique of edge detection, on the results of detection of vehicle license plates. edge detection method on the dispatcher of the good according to the results of the sobel operator i.e. matrix confussion and prewitt operators. With the level of accuracy of 60% while the sobel operator prewitt 63% success rate. But on each operator as explained above that still has weaknesses, namely apabil objects more than 2 objects, and when there is excess light reflection around the object that you want to detect. Keywords: edge detection, confussion, matrix methods, detection.

Abstract:
This study discusses the infrastructure facilities management system in universities. The system is designed using Near Field Communication technology that uses an Android smartphone to support the use of this system and also the web using PHP and MYSQLi programming languages for online data storage. The method used in designing this system is the Waterfall model. This system modeling uses the UML language (Unified Modeling Language). This research was conducted at Pelita Indonesia College. The results showed that the use of Infrastructure Facilities System using Android-based NFC technology is easy to use for Staff and Infrastructure Heads in managing their inventory. Keywords : Infrastructure Facilities, Universities, Near Field Communication, Android. ABSTRAK Penelitian ini membahas tentang sistem manajemen sarana prasarana pada perguruan tinggi.

Abstract:
Expert System is a computer-based system that uses knowledge, facts and reasoning techniques in solving problems that normally can only be solved by an expert in the field. Many cases can be used as research in Expert Systems, one diagnosis of proper nutrition. In this study we will design an expert system to diagnose the type of proper nutrition for pregnant women. Determining the proper nutrition for pregnant women is important to note because it causes birth defects and infant mortality. In this study, the system uses the Backward Chaining method in determining the proper nutrition for pregnant women. This system can provide the right solution for pregnant women. This application is made to the programming language PHP and MySQL as its knowledge base storage. System testing is done by matching the search process Backward Chaining in the decision tree to determine the proper nutrition for pregnant women at the design stage to the actual system that has been built. Keywords : Expert System, diagnose, Backward Chaining, Nutrition, Pregnancy

Abstract:
Determination of the personality of elementary school students with Case Based Reasoning method is an activity to map student behavior in school so that student mischief can be directed into something that can support student's success in learning and teaching process. With Case Based Reasoning is a method of searching in a regular system of experts and widely used psychological problem calculations. In this method there are 4 stages namely Retrieve, Reuse, Revise, and Retain. Because primary school in its special area is very far from the primary school in the city on the sensitivity of the principal's head evaluates the learning process of the students and the desired learning according to the character of the students Keywords : Expert System, Personality, Case Based Reasoning
