Abstract

Gathot Hybrid adalah sebuah system terintegrasi yang diciptakan untuk melindungi server dan aplikasi web dari berbagai serangan dan ancaman attacker (Intrusion Prevention System). Dibangun dengan teknik khusus, didasarkan pada penelitian dan pengamatan yang mendalam dengan mempertimbangkan berbagai variable yang mempengaruhi. Sehingga diharapkan dapat melindungi atau meminimalisir kerusakan yang ditimbulkan oleh attacker. Menggabungkan methode lama dari sebuah perangkat deteksi intrusi dengan methode baru hasil research. Sehingga diharapkan menghasilkan aplikasi yang tangguh. Mengintegrasikan perangkat keamanan yang selama ini terpisah dan bekerja secara sendiri-sendiri, menjadi satu kesatuan. Deteksi serangan dari signature. Deteksi serangan dari log file. Proteksi dengan firewall dan drop packet data yang mencurigakan. Daftar riwayat attacking. Daftar host terkarantina akibat terdeteksi sebagai sebuah serangan. System peringatan dini dengan email dan SMS. Grafik attacking. Kemudahan dalam administrasi (web based)

Abstract

SQL injection attacks toward web application increasingly prevalent. Testing to the web that will published is the one of preventive measures. However, this method sometimes ineffective because constrained by various things. Instrusion detection system (IDS) is able to help protect the website from various attacks. This study proposed an IDS for web applications from SQL injection-based attacks. The IDS is based on hybrid architecture with a signature-based detection method, type of data to analyzed is network packet and error log. The fuzzy logic inference engine used to be drawn the conclusion based on analyzed data.Proposed hybrid IDS has good result on detecting the various type of SQL injection attack and significantly reduce or even remove the false positive and false negative.Keywords: hybrid intrusion detection sistem, signature-based IDS, sql injection, fuzzy logic.

Abstract

Conventional presence system have many limitation, in between difficulties in recording data that can have impact on the controlling from lecturer. In the other conventional presence systems are often fraudulent. This research purpose to design and developing electronic presence system in class room that are effective and efficient. In this research we are use biometric fingerprint sensor. There are several stages in this research. The first stage is the needs analysis to explore data and information and then formulate solutions to existing problems. The second stage is system design which includes system architecture design, system workflow design, data flow design, and database design. The third stage is the implementation of the system using programming languages and database software that is applied to microcomputers. The fourth stage is testing the system using black box testing. The last stage of this system development research is evaluation. This research took a case study at the Institut Teknologi Sumatera (ITERA).

Abstract

Sliding Mode Control (SMC) used to control the stability of a quadcopter from disturbances and uncertainties. This technique has two main advantages: the nonlinear dynamics and modelling errors of the quadcopter can be eliminated by switching function and the uncertainty problem can be overcome with a closed-loop response. The controller of the sliding mode technique consists of two components. The first is design equivalent control law to maintain the system state trajectory on the sliding surface. The second is design switching control law to reach the sliding surface. The Lyapunov theorem is used to ensure the stability of the system. Simulation results verify the robustness of the controller.

Abstract

Abstrak            Bangsa yang besar adalah bangsa yang menghargai sejarah dan asal usulnya. Relief yang terdapat pada candi Borobudur menggambarkan banyak cerita, termasuk sejarah dan asal usul bangsa ini. Mulai dari cerita kehidupan kalangan kerajaan, kehidupan masyarakat, dan adat istiadat pada saat bangunan candi tersebut dibuat, dsb.            Penelitian ini merancang sebuah perangkat lunak mobile Android untuk identifikasi citra relief Candi Borobudur sehingga dapat membantu wisatawan dalam menerjemahkan pesan dan informasi yang terkandung didalamnya. Metode ekstraksi ciri yang digunakan adalah Speeded-Up Robust Feature (SURF) dan hierarchical k-means tree nearest-neighbor untuk identifikasinya.            Pengujian identifikasi citra relief dilakukan dengan berbagai macam variasi, yaitu sudut, jarak, rotasi, intensitas cahaya dan keutuhan citra masukan untuk melihat pengaruhnya terhadap hasil pengenalan citra relief tersebut. Metode identifikasi yang diajukan memberikan hasil pengenalan sebesar 93.30% dengan rata-rata waktu komputasi 59.55 detik.  Abstract            The great nation built from people who can respects they history and origins. Reliefs at Borobudur temple contained many stories, including the history and origins of this nation. Starting from the life story of the royal, society, and customs at the time of the building of the temple was made, and so on.            This study develops mobile Android software for identification of Borobudur Temple relief image object so that it can help travelers in translating the story and the information contained therein. Feature extraction method used is speeded-Up Robust Feature (SURF) and hierarchical k-means tree nearest-neighbor for identification.            Identification testing of relief images is done by different variations, ie angle, distance, rotation, intensity of the light and wholeness of image input to see the effect on the relief image recognition results. The proposed identification method gives recognition results of 93.30% and the average computation time for 59.55 seconds.
