Abstract

Metode Median Filter adalah salah satu metode perbaikan kualitas citra pada domain spatial. Domain spatial memiliki kelebihan pada hasil perbaikan karena perbaikan citra dilakukan per-pixel. Karena perbaikan citra dilakukan terhadap pixel, metode Median Filter memiliki komputasi yang tinggi dan waktu eksekusi yang lama.Dengan melakukan penyeleksian terhadap pixel yang perlu diperbaiki dapat mengurangi waktu proses perbaikan dan meningkatkan kualitas citra karena pixel yang sudah benar, tidak perlu diperbaiki. Pengukuran kualitas citra dilakukan menggunakan Peak Signal to Noise Ratio (PSNR) dengan membandingkan nilai citra asli dengan citra hasil perbaikan. Nilai PSNR ideal untuk disebut sebagai citra yang baik adalah 30dB.Kualitas Citra metode Median Filter dengan penyeleksian memiliki kenaikan nilai PSNR sebesar 5.6% dan memiliki kenaikan kecepatan waktu proses perbaikan kualitas citra sebesar 8.3% dibanding merubah semua nilai pixel citra

Abstract

In managing a server, an administrator takes a variety of ways for ensuring the safety and cosiness of the system. One type of threat that attack on the server is done on a port that is in an open state, thus making people who do not have access rights to perform port scanning to infiltrate into the server. One solution to cope with the attack on the port can be done by using port knocking. Port knocking is a method that can be applied to the server with the workings of such a code to unlock the safe. Port knocking is done by inserting a predetermined port sequenced to open a specific port. At the port sequenced delivery process takes an additional authentication likes keyport. Anggi algorithm (AA) is an algorithm that is built by combination o f Diffie-Hellman and RC4. The algorithm is used for encryption and descriptions a keyport from client side to the server side. In the process of sending a keyport to be modified by using the arithmetic calculation. Process of encryption and description keyport is done to prevent some attacks on the server by hackers with extracting such information after successfully breaking into a port. The results o f implementation AA algorithm on the process of port knocking can secure the delivery process o f keyport and improve the security o f server.

Abstract

Along with the rapid growth of the Internet, causing problem in the allocation of IPv4 addressing. Therefore, IPv4 only have less than 4 billion addresses and will soon be exhausted. Therefore, IPv6 has been created and used hexadecimal system on it addressing and has very large address allocation that is 3,4 x 1038 addresses. But now many network infrastructures in terms of hardware and software that have not fully support IPv6. So, the devices that still using IPv4 can through IPv6-based network infrastructures, they can use tunneling technique. This makes the emergence of the idea to test the delay and throughput in streaming video system which has a heavy workload on the network. Video streaming system on Vision 1.0 application takes advantage motor stepper webcam in order to support the visibility of the image that can be captured. Then the client who connected to the server can control remotely the motor stepper webcam. On the implementation phase, Vision 1.0 is running on IPv4 and IPv6 network. Next on the testing phase, carried out delay and throughput data collections from those both network systems. From the obtained results in testing, showed no significant difference. So, in general, the performance difference is not too pronounced when the video streaming system is running on both network systems. However, from a comparison based on mean value of delay and throughput, IPv4 is still superior due to the header of the data packet does not as big asIPv6 header which of course affects the packet data frame size, then the traffic network more crowded.

Abstract

Many colleges already apply web based academic information system use internet connection, so it is need a system security to protect from attacks such as SQL Injection and Brute Force. Honeypot is a system security which devide two system that are original and fake system. Original system used by user to access academic information system that source from correct database. While fake system used to separate hacker and user. Hackers who try to enter with SQL Injection is send to fake system directly which has wrong data. This fake system seems correct and all action that was happened in will be noted on log history. When hacker try some password ese Brute Force, system will reset user password automatically. This system already test with 79 times SQL Injection and 29 times Brute Force attack. All attacks can handle nicely with honeypot algorithm.

Abstract

Practicum registration systems that exist on campus STTA previously done manually, where students will sign up to the admin to bring proof of payment practicum. Students are free to choose his own class, this often resulted in unbalanced number of students in the classroom lab that is consideredless  effective way. This makes the emergence of the idea to establish an MM algorithm is applied to a practical application o f automation systems. MM algorithm works by determining many lab classes based on students who took the KRS. Furthermore, students who have paid practicum will be immediately incorporated into the classes that are available with regard to the number of students and GPA o f students per class, so it will obtain practical classes by the number o f students and the average GPA o f each class balanced.Concept application using client-server database, where the database is on the Local Area Network (LAN) STTA. To facilitate the management admin, then the application will be tested on the LAN network and VPN (Virtual Private Network) network. LAN is a computers network that are connected to a computer server by using specific topologies, typically used in areas of the building or area a distance o f not more than 1 km (local area). While VPN is a secure way to access the Local Area Network that is in range, using the Internet or other public network to perform packet data transmission in private. By using a VPN, users can access the computer that is on the LAN even though the user is not in the same location with a LAN.

Abstract

Along with the development of current technology, making technology is very important in today's life. Security level digital data has become more vulnerable to exploitation, the problem arises when an information technology device was attacked by people who do not want to take a responsible and important data illegally, so the administrator must act quickly to secure important data. Making a data security technology on the internet is very important information. Limitations administrator underlying the creation of a system that is able to detect and defense systems against such attacks is automation, so that it can be applied to data security. The system is built to prevent attacks on computer networks with more specific on THC - Hydra. This system will analyze the number of errors in the log into the database, and if the error exceeds the tolerance rules are made by the administrator. If the error is more than 3 times in one minute, then with automation, the system will create a rule that can imprison users who do not have such access, and access to the prison in the illegal user can not perform such activities on legal access and access to activities conducted illegal user can be recorded on a file and jail.txt. So under any circumstances and not in supervising administrator, the security of other user data will be safe and can not be retrieved or viewed by a user of illegal access.
