Abstract

Software Defined Networking is the latest breakthrough in modern network modeling where control plane and data plane have been separated from each other. Where on the SDN control plane is placed on the controller in charge of organizing and providing all the needs that exist in the network. The controller will monitor the state of the network and also perform the repair process in case of damage to the network, one of which can be caused by Denial of Service (DoS) and Distributed - Denial of Service (DDoS) Attacks attacks. With implementing a centralized firewall on the controller, the controller can quickly detect when a network attacks occurs either by hosts hosted on their domains or by hosts in other network domains, so the process of own attack subscribing becomes faster and more effective. That things proved based on the average attack time the required subscription is about 6.042 seconds with average use of cpu resource is 18.4% and bitrate received by host victim 13.582 Kbps after attacking by the controller, indicating that the implementation of centralized firewall in the controller can quickly detect and subscribe to attack that occur, using a resource cpu that is not too large and pressing the number of packets of data sent so as to save on bandwidth usage in the network.

Abstract

Website is one of the media in spreading information, one of them is Ki Purbo Asmoro website. However, some shortages were found by the users when accessing the website. To find out the problems on the website, an analysis of user experience through Heuristic Evaluation method was needed. In addition, to know further about the impression, goals, and expectations of the users in using the website, a Persona as a fictional representation of the potential users of the website was formed. Evaluation was done in 2 stages. The evaluation of the phase 1 was to find problems on the initial website. The evaluation of the phase 2 was to find the problem on the repair prototype that built on the solution to the problems found in phase 1 and Persona evaluations. In the result of the evaluation of the phase 1, the most problems in the heuristic principle found were in the principle of H4 - Consistency and Standards, and on H8 - Aesthetic and Minimalist Design. While in the evaluation of the phase 2 some problems were found on the principle of H4 - Consistency and Standards, and H7 - Flexibility and Efficiency of use. Some improvements were made to decrease the number of problem findings and severity ratings between the two evaluation phases.

Abstract

Sales pattern is one of the methods that can be used to determine sales strategy such as the products placement and promo, by seeing on how often an item purchased simultaneously in a retail store. Data mining is used for analyzing the big data to find inter-data connection and to generate useful informations for the users. So, this study used sales transaction data to determine sales pattern by using association rule and algorithm Modified-Apriori. Association rule is a method used for finding unique connection hid in big data by using the calculation of the value of support and confidence. Algorithm modified Apriori is the development of the Apriori algorithm which searches frequent itemset and joining and pruning process, then as a result, it produces faster time efficiency by using HashMap technique instead of Apriori algorithm. The results obtained from this study are the highest value of the minimum support is 9% and the highest value of minimum confidence is 80%. The length of the itemset are 2-itemset and 3-itemset. Test which used lift ratio generates rule which has value of more than 1.
