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.

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).

Informasi terkait kegiatan penerimaan mahasiswa baru (PMB) sesungguhnya telah banyak tersedia pada halaman web maupun brosur. Namun demikian, dimungkinkan terdapat berbagai informasi yang tidak dapat ditemukan secara langsung dalam media tersebut. Penggunaan mesin pencari juga tidak menjamin pengguna untuk mendapatkan informasi atau jawaban yang relevan dengan kebutuhan. Melakukan kunjungan ke kampus seringkali terkendala oleh jarak, waktu, dan jam kerja. Dalam penelitian ini, dikembangkan sebuah question answering system (QAS) terkait penerimaan mahasiswa baru agar pengguna mendapakan informasi yang sesuai dengan kebutuhannya, selalu bernilai benar, dan dapat diakses kapan saja. QAS dibangun dengan arsitektur tree tier dengan aplikasi mobile sebagai antarmuka, memanfaatkan metode pengolahan bahasa alami dalam memproses pertanyaan pengguna, dan ontologi sebagai basis pengetahuannya. Penelitian ini menggunakan model pengembangan SDLC, dengan model analisis yang digunakan yaitu: analisis kebutuhan sistem, analisis rancangan sistem, implementasi sistem, dan pengujian sistem. Pengujian terhadap sistem dilakukan dengan beberapa cara, yaitu: usability testing, dan pengujian akurasi jawaban. Pengujian menunjukkan QAS yang dibangun dapat diimplementasikan dengan baik sesuai dengan kebutuhan dengan akurasi jawaban sebesar 82.14%. AbstractThe information regarding student admissions and related activities can be found and widely available on website or brochures. However, it is possible that the relevant information cannot be found directly from the media. The use of search engines also doesn’t guarantee users to get the relevant answer or information that satisfy their needs. Visiting the campus is often constrained by distance, time or working hours. In this study, a question answering system related to student admissions was developed so that users get the information that fits thier need, always give the correct answers, and can be accessed anytime. The QAS is built with a tree tier architecture with a mobile application as an interface. Natural language processing methods uses to process user questions, and ontology uses as the knowledge base. This study uses the SDLC development model, with the analysis model used namely: system requirements analysis, system design analysis, system implementation, and system testing. Testing the system is done by several ways, namely: usability testing, and test the accuracy of answers. The tests shows that the QAS can successfully implemented according to the requirement, with the accuracy of answer is 82.14%.

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.

The Implementation of Distance-Angle Signature as Object Shape Identifier for Digital Images Andika Setiawan; Rajif Agung Yunmar

Publisher : STEKOM PRESS

The transformation of objects in computer graphics is very closely related to the factor of scale and rotation. Both are often a challenge in the introduction of objects through numerical features in digital images. Feature processing techniques that can overcome these problems such as Distance - Angle signature that is invariant to the scale and rotation factor. From the results of experiments conducted on 5 types of geometric shape images which amounted to 15 data with scale and rotation factors obtained the results that the Angle Signature can be applied well on all data. Inequality in the signature plot images obtained is due to the lighting conditions and background objects that are not uniform, which occurs in the image of a circle for all three types.

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.
