The development of information technology that has an impact on behavior and culture in business can be so easy and fast. It becomes a challenge for a company to be able to balance and play an active role in order to compete in the business world. In this study researchers tried to model the ERP concept as the basic foundation of integrated business processes. The usecase and squares diagrams are used as business process modeling. the implementation of software development involving modules, views and controllers reinforced with the LRS design is used to display database connectivity. The basis path test gives results with value 3 is an use of algorithms in low risk categories. Validation testing with valid results becomes a response with fulfilled functional requirements. While the results of testing non-functional requirements related to usability through the calculation of the T test where t hit = 4.580> t 0.05, 9 = 2.265, indicating that the system application is acceptable and influences the efficiency and effectiveness of work.

As we know, Indonesia has a dynamic structure of the earth's surface layer. This topographic differences level was results in land variations and it impacts on the material contained in it. This certainly will growth an enrich amount of natural land resources and the quality of plant vegetation and the sea. All of them are natural resources that are beneficial for human survival and the other habitats. To monitoring its management from the surface, we need a method that serves to inform the potential region conditions, one of them is the Geospatial Information System (GIS). Generally, taken data for GIS could be obtained through aerial photography of satellite images. However, the results are less accurate, so that, we look for the other alternatif instruments, which could made a GIS map better, using the design of unmanned aircraft vehicle (PTTA) or commonly known as drones. For now, Unmanmed Aircraft Vehicle is a currently technology which that is growing rapidly. On this occasion, the author will introduce UAV technology that can be designed by itself according to needed, and could be able to answer every problems in which related to image mapping from geospatial information systems.

Transportation of education through the use of technology can support educators’ task and stimulate interest in learning among students. This research is conducted to find out the factors that influence whether Interactive Learning to Read Software for Early Childhood is well received by its users or not and to determine the causal relationship among the factors that affecting the acceptance of such software. The model used to determine the acceptance of the software Learn How to Read for Early Childhood is TAM (Technology Acceptance Model). TAM explains in detail the model of information technology acceptance with a certain dimension that can affect technology acceptance by users. This model puts factors of attitude and behavior of each user by using two main variables, namely expediency (usefulness) and ease of use (easy to use). The model of acceptance of Learning to Read Software for Early Childhood software is also influenced by other factors such as: Computer Self Efficacy (CSE), Perception of Ease of Use (PEOU), Perception of Usefulness (PU), Attitude toward Using (ATU), Behavioral Intention To Use (BITU), and Actual System Use (ASU). Statistical test is performed using Structural Equations Modeling (SEM), which are processed by applying software AMOS version 7.0. The result of the research shows that the reading software is well accepted by kindergarten children.

The rapid development in the telecommunications and digital world today makes android-based mobile devices basic needs for many people. The devices have even provided various kinds of learning media for the community. Further, even though the devices are easily to apply as learning media, they have not been a priority for Muslims in improving their knowledge, such as Sirah Shahabiyah (the journey of a female companion of the Prophet Muhammad). Due to the community’s little interests in learning Sirah Shahabiyah, it is necessary to create a learning application that allows the user and the community to easily learn it. The methods used to collect the data of this research are field study, literature review and previous literature review. The system is developed using a prototype system development method consisting of the stages of planning, analysis, design and implementation and is designed using Unified Modeling Language (UML). The result of this research is a learning application in the form of android-based Sirah Shahabiyah, by which the user and the community can easily learn Sirah Sahabiyah, facilitating pleasant and effective learning activities.

The number of patients with Chronic Kidney every year always increases. One of the causes is the late diagnosis to be known and the existence of an unfavorable lifestyle. The United Nations Alliance (WHO) estimates that in Indonesia there will be an increase in kidney failure patients until 2025 by 41.4%. In this study an expert system for diagnosing Chronic Kidney disease will be made using the FIS - Sugeno method. The variables used in the formation of fuzzy sets which are variable sets of laboratory results include creatinine, urea, hemoglobin, blood pH, urine albumin, and gout. Variables that have been entered in the fuzzy set are formed by a combination of one variable with the linguistics of each then the fuzzy set will be processed by the FIS-Sugeno method with the help of the Matlab Toolbox so as to produce a decision in the form of chronic kidney negatives, chronic pre kidney or chronic kidney positives. This application was tested by involving medical records of diagnoses from doctors using variables: creatinine, urea, hemoglobin, blood pH, albumin and acidic letters. The results of the decisions generated from the application using the Sugis-FIS method resulted in accurate decisions for users in diagnosing chronic kidney disease. Thus in general this application can be used to assist in the diagnosis of chronic kidney disease so that the spread of the disease can be suppressed as much as possible.

Publisher : Universitas Indraprasta PGRI Jakarta

Salah satu masalah pendidikan saat ini yang dihadapi oleh bangsa Indonesia adalah bagaimana meningkatkan mutu pendidikan disetiap jenjang. Adakalanya memang benar sang pelajar tidak mampu secara finansial, tapi tak jarang dari kalangan mampu pun memanfaatkan surat ini. Yang penting bisa sekolah gratis. Jikalau targetnya adalah sekolah gratis tanpa pertanggungjawabkan “ beasiswa” yang diterima, seharusnya lembaga pendidikan mematok beberapa peraturan yang memacu prestasi penerima beasiswa. Oleh karena itu dalam penelitian ini dilakukan komparasi algoritma C4.5, naïve bayes dan neural network yang diaplikasikan terhadap data siswa yang menerima beasiswa. Penelitian ini bertujuan untuk mengukur tingkat akurasi dari kajian komparasi 3 buah algoritma dalam pemilihan calon penerima beasiswa di SMA Muhammadiyah 4 Jakarta. Dari hasil pengujian dengan mengukur kinerja ketiga algoritma tersebut menggunakan metode pengujian Cross Validation, Confusion Matrix dan Kurva ROC, diketahui bahwa algoritma Naïve Bayes memiliki nilai accuracypaling tinggi, yaitu 86.5672%, diikuti oleh metode C4.5 dengan accuracy sebesar 67.1642% dan yang terendah adalah metode Neural Network dengan nilai accuracy 82.0896.
