Soccer Game Optimization: Fundamental Concept
No full textOptimization is important in science, engineering, economic as well as daily problems. The number of optimization methods increase continuously due to the growing optimization problems. In this study, we discussed the fundamental concept of soccer game optimization (SGO), a new algorithm inspired by the soccer player movements. The method consists of two basic movements; the move off and the move forward, to control the diversification and intensification and a player substitution procedure to keep the good solution during the search. The SGO elaborates the competition and the reproduction process in evolutionary algorithm with the powerful information sharing of swarm intelligence algorithm. As a new method, the SGO can be enhanced in many different ways such as elaborating more aspects of the soccer players’ movement as well as implementing the proposed method to solve various optimization problem
Integrasi Sharepoint Portal dan Office Web Application untuk Mendukung Layanan Cloud
No full textAbstract – Nowadays, information technology has been entering new era of cloud computing, whereas internet user can save and manipulate their file using the cloud. For more, not only provides storage and manipulation function, cloud can be used for document approval between employee to their manager. One of many solution to accommodate the needs mentioned above is sharepoint application by Microsoft. Web application maintained by sharepoint can be used as user interface to collaborate between users. To support document sharing and manipulation, sharepoint can be integrated with Office Web Application (OWA). By using OWA, user will meet experience using Microsoft Office through web browser. Considering Microsoft Office used by most people, the integration between sharepoint as web application farm and Office Web Application can be an altertative to enter cloud computing er
Implementasi Multithreading Untuk Meningkatkan Kinerja Information Retrieval Dengan Metode GVSM
No full textGVSM is one of the models of IR systems. GVSM divided into two processes i.e. preprocessing process namely reading the text (*.pdf, *.doc,*.docx), tokenization, filtration, stemming, and parse the query and the process of calculating the relevance of the document that has been done preprocessing with user query to get the value of similarity. In general, to determine of the effectiveness of IR application is determined by two factors, namely recall and precision [7,8,10]. According to Järvelin and Ingwersen, the effectiveness of IR application is not only determined by the recall and precision, but rather the ability of IR applications in helping users to complete the search more effective and efficient. The effectiveness of an IR application is determined by recall, precision, time requirements, and reporting documents are presented to the user [7]. To improve the performance of IR applications in time requirements is implemented multithreading in the preprocessing process, i.e. stage 1 to stage 4 GVSM method. The result showed that the method GVSM able to rediscover relevant documents with 100% the precision value, to get the recall value which is equal to the same documents collection either with or without multithreading, but can save processing time by over 50 %
Sistem Pendukung Keputusan Pengelompokan Siswa Berdasarkan Gaya Belajar Felder-Silverman
No full textPenerapan teknologi informasi dalam bidang edukasi dewasa ini meningkat pesat. Penerapan TI tersebut tidak hanya dalam penggunaan media pembelajaran berbasis multimedia saja, tetapi juga dalam pelaksanaan pembelajaran berupa e-learning, Dalam perkembangannya, agar proses pembelajaran berjalan dengan efektif, maka diperlukan belajar secara berkelompok. Ide tersebut bukanlah suatu hal baru karena bekerja dalam kelompok memberikan lingkungan untuk belajar secara kolaboratif serta berbagi ide dan pengetahuan. Agar tiap anggota kelompok merasa nyaman, maka siswa dikelompokkan berdasarkan gaya belajar yang dimilikinya. Dari hasil kuesioner gaya belajar siswa, kemudian dilakukan teknik clustering fuzzy c-means untuk membentuk kelompok siswa. Hasil clustering tersebut kemudian dianalisa dengan menggunakan indeks Davis-Bouldin. Dari hasil ujicoba menunjukkan bahwa hasil clustering paling homogen ketika set parameter jumlah cluster = 4 dan jumlah iterasi = 20 kali
Implematasi Aeschipper Class Untuk Enkripsi URL di Sistem Informasi Akademik Fakultas Teknik Universitas Diponegoro
No full textIn web programming GET method can use to send data from client to server. Weaknees of the GET method is the appearance of transmitted data or variables in the URL. Users can easily change variables used and when it is executed, variable data will also be executed. It is very vulnerable to attack by malicious users with some techniques such as XSS or SQL injection. These weaknesses can be resolved with use encryption techniques to URLs that use the GET method, such as AES encryption. The process is encrypt variables on client side and decrypt on server side to retrieve actual data. Thus variable is not shown in the URL, so if there will be an attack attempt difficult. Academic Information System (AIS) of Engineering Faculty, as a web-based application also uses several modules that use the GET method for sending data. Thus addition of the security level using the URL encryption is needed to improve security of system and data on the AIS. The result is a variable that is sent with GET method is not display on URL on three modules, namely the main menu page, change the password and a link out of the syste . The encryption process adds time access to system by an average of 0:05 s, so that the outline does not affect system performance . Keywords: web applications, POST and GET, URL, encryption, AES, academic information system
