Abstract

Learning media that has been widely created and implemented in high schools and universities will certainly help students understand existing subjects, especially subjects related to theoretical arithmetic. Mathematical logic is certainly widely used in the development of computerization, computerization in the development of computer applications also has to do with arithmetic relations for the part of the process.Software engineering methods use prototypes to develop or develop system applications that have several steps, such as: Listen to Customer, Build / Revise mock-ups, Costumer Test. Completion of the stages of building automata learning applications is part of the development stage of the automata learning system application with the application of Finite State Automata (FSA).Application results with a GUI-based (User Interface Graph) design implemented to support the automata course material. Graphic automata application implementation to show the relationship between states resulting from the logic of the relationship results from each existing node. The resulting application has 2 important parts for the design stages, namely: process design (flowchart) and interface (Morkup). The results of all designs are further implemented with the Borlan Delphi visual programming language application. Testing with black box is done with a visual Graph verification scenario which is inputted with the suitability of the input and which is not to see the results of Tupel based on the graph that is successful and not successful. Keywords: automata, learning, application, Graph, Tupel.

Abstract

Dalam penelitian ini dilakukan pengujian performa menggunakan metode k-means dan naïve bayes dalam mengelompokkan dan mengklasifikasikan dua jenis set data citra dengan pola tekstur yang berbeda. Set data yang diuji merupakan set data citra pola batik dan set data pola brodatz,  fitur ciri pola citra yang digunakan pada penelitian ini adalah fitur contrast dan energy yang didapatkan menggunakan metode gray level co-occurance matrix (GLCM). Hasil pengujian menggunakan  parameter akurasi prediksi memperlihatkan bahwa set data citra pola brodatz mempunyai akurasi prediksi yang lebih baik dibandingkan set data citra pola batik yaitu dengan selisih nilai sebesar 1.52 %. Untuk parameter waktu dalam menghasilkan nilai fitur contrast dan energy set data citra pola batik lebih cepat mengenerate jika dibandingkan dengan set data citra pola brodatz dengan selisih waktu 27.8 milidetik. Hasil serupa juga terjadi pada pengujian berdasarkan parameter waktu prediksi, dimana waktu prediksi set data citra pola batik lebih cepat dibandingkan dengan set data citra pola brodatz dengan selisih waktu 30.6 milidetik. Dari pengujian menggunakan parameter waktu maka dapat disimpulkan bahwa set data citra pola brodatz memerlukan waktu lebih lama dikarenakan pola teksturnya yang tidak seragam yaitu dalam satu citra terdapat pola halus dan kasar dikarenakan citra merupakan citra dengan tekstur alami, berbeda dengan citra pola batik yang memiliki keseragaman pengulangan pola sehingga tekstur lebih teratur.

Abstract

Today, many of schools still use the same old way to process students’ registration. This kind of way is obliged the students who want to enroll as new students in a certain school to come to its physical building. They have to be there to register or find some information about registration requirements, registration dates, test dates, and other possible information. This makes the students need to provide certain time and cost. This problem needs a system to help both students and school authorities to register and manage data of the new students. This information system uses certain phases to identify the problem which later become the reason of why this system is conducted. When conducting this information system, the researcher collects the data using Waterfall method based on Sommerville reference which has five phases such as analysing data needed, designing system, composing programme code, testing programme, applying program and maintaining. This system is designed and modelled the data using DFD and ERD. Besides, this system also uses PHP and XAMPP.This data which consists of data and bundle of new students can be accessed by the administrators (the system’s organizer), the school administrators, the new students, and other visitors. This system offers features that can be freely accessed such as search school, help, account register, school schedule, school profile, manage students’ data, and announcement. This design is tested by Black Box Testing to observe the testing result of each menu and to check functions of the software. Keywords : Information system, new students registration, website
