Abstract

XYZ is a company that sells services and solutions to customer problems, services and solutions sold are products that have been developed previously by PT. XYZ and will continue to be developed to adjust the addition of functions according to customer demand. To be able to achieve the vision and mission of an organization, PT. XYZ must have a good software development business process. Currently, the service and solution development process still not have a written Standard OperationaI Procedure (SOP) that can be the problem in evaluating system performance and the passing of a product from a predetermined time limit. Therefore, we need to carry out further evaluations so as not to have a negative impact on the product development process. EvaIuation is done by using interview sources and event logs that use process mining methods to further process and analyze event logs with the help of Disco and ProM 6 Tools. After that, the evacuation process will be continued by using the Quality Evaluation Framework (QEF) to compare the target values with the interview results and event log values. The evaluation results have 13 quality factors were concerned, 4 quality factors including those that were not in line with the company's target because the processing time recorded in the event log exceeded the target. The activities listed in the event log are not procedurally appropriate, such as processes that were not closed for a long time and processes that have the same start and finish time.

Abstract

The judge is an official who can try in a court of law in a country. Every day the head of the court makes a judge's decision to handle cases of various types and classifications. Cases that are registered by the plaintiff for each day have an average of 8 to 10 cases and for each week 35 to 40 cases. Whereas the judge's appointment time is quite short, which is a maximum of 3 days and at least 1 day. The head of the court experienced a difficulty in making a judge's decision because of the fairly short amount and timing of the stipulation. Then a system is needed that hopes to help the effectiveness of the selection of a judge so that the determination of the judge is faster and does not exceed the predetermined time limit. The method used in determining this judge is the Analytical Hierarchy Process. The criteria used are leadership, cases handled, and length of decision. Each criterion has sub-criteria, namely: cases handled have the same type and classification sub-criteria, different types but the same classification, different types and classifications. The length of the verdict has sub-criteria is not good, the decision is long enough, long the decision is good, and the decision is very good for a long time. Leadership has sub-criteria of chairpersons, member judges, and single judges. The system output results in 5 alternative order judges with the highest to lowest values. Spearman rank correlation method as a method of testing the results of the system with results from experts. From the tests that have been done, it is obtained a correlation value of 0.646, the value means that the correlation obtained from the comparison of system results and experts is a strong correlation.

Abstract

Malang District's health service offices own a pilot project whose objective is to record in the form of causes of death in the region Gondanglegi and Kepanjen. One of the ways to record such data is through verbal autopsy which is done by interviewing family members of the deceased on visible signs or symptoms of a certain individual before death. The ongoing process of the verbal autopsy is still recorded manually using paper, which when gathered is vulnerable to being lost or damaged. Otherwise, there was no system to record the data that has been gathered. Based on the above-mentioned problem, an information system is needed to ease the recording, storing, and processing of data that contains verbal autopsy. The development of the information system uses a prototyping method which presents a picture of the system in general toward the client in order to gain feedback in the form of advice or critique. Development is started with the modeling of the business process and requirements of the analysis, prototype designing, prototype evaluation, continued designing, which is finished with implementation and testing. The implementation results in a web-based verbal autopsy information system. The system is utilized to record, verify, manage, and manage verbal autopsy data and to present general information. The next step is to test the implementation results with validation testing which shows valid test results which are in accord with the identified requirements, tests towards the compatibility of the browser show that the error issues were at 9% and the system was run on a variety of browsers without any problems whatsoever.

Abstract

Distributed Denial of Service (DDoS) are common and popular attacks on the SDN layer, namely the data plane. In this study, Athena-based Intrusion Prevention System (IPS) is applied to prevent and reduce the impact of DDoS attacks, especially TCP SYN flood and UDP flood. Two test scenarios were carried out to determine the IPS performance. The first scenario, comparing the impact of DDoS attacks without and with applied IPS to throughput and CPU usage on the controller. The second scenario, comparing the speed of the prevention function based on features in the detection model. The first test results show that IPS is able to prevent DDoS attacks as proven by the decrease in the throughput. The throughput when normal and IPS is applied against TCP SYN flood and UDP flood attacks for transmit parameters of 3956 pps, 4045 pps and 3919 pps while for receive parameters it is 4720 pps, 4793 pps and 4692 pps. IPS is also able to reduce the CPU load on the controller when those attacks are carried out each at 4.95% and 7.9%. The second test result concludes that the more appropriate and correct features are used for training, the faster IPS in recognizing the characteristics of dangerous hosts. This is proven by the average speed of prevention for each attack using 10 features each at 5.78 seconds and 5.99 seconds while the 5 features each at 12.42 seconds and 11.42 seconds. Moreover, IPS can be applied to hardware with specifications as in this study.

Abstract

Ragnarok M: eternal love is an online game that released on October 30, 2018, is a mobile game version of the Ragnarok computer. Ragnarok is a popular game in Indonesia until now the players in this game reach 62 million people. With it, this game has the potential to attract old and new players to play, even though the platforms are different. So the user experience is important for the success of this game on the market, especially if the application has just been released. Applications that are made poorly and are difficult to use will make it difficult for users to use and learn, so it will rarely be used and not sold in the market. To get a good user experience, an evaluation is necessary. The Cognitive Walkthrough is a user experience evaluation method where evaluators provide scenario-based tasks and questions to users to find problems that interfere with the learning and understanding process. The method is well used in new applications because they can find the cognitive processes of users when they first use the application and get the weakness of it. The results of the evaluation show that the problem that occurs is the lack of understanding of the game in the gameplay tasks, displays that are difficult to understand on the task of logging and hidden key issues in gameplay tasks. Even though there is a problem, the problem is a mild problem that does not affect the main function in the game.
