Abstract

YouTube is the world's largest online video social media that is used to display various videos created by users and companies in the field of media content. Every video contained in YouTube can be done by giving a text type comment in the comments column of the video that has been watched. The large number of comments causes the content creator (video maker) to spend enough time to understand every emotion in the existing comment. After consideration of the solution used to resolve the problem, the authors chose to use the Modified K-Nearest Neighbor (MKNN) classification method with BM25 and Chi-Square feature selection. The test used is 5-fold cross validation to find the best k value which is then used for testing the Chi-Square feature selection. In Chi-Square test the data used is the best fold data based on the highest f-measure value in the 5-fold cross validation test. The results obtained are the maximum accuracy, precision, recall, f-measure values ​​achieved when k is 30, 72,82%, 72,94%, 72,26%, and 72,59%. While the Chi-Square test on the 4th fold of data the best number of terms used is 40% and 50%, with the value of accuracy, precision, recall, f-measure is 80,56%, 80,37%, 81,61 % and 80,98%.

Abstract

The meeting is part of an important activity of the civitas employee in the Faculty of Computer Science, Brawijaya University to negotiate or resolve a problem that concerns the common interest, or development of the Faculty. The thing that must be ready in meeting activities is to make the meeting agenda and make minutes of the meeting. Making minutes of the results of this meeting is important, to help the accreditation process or re-accreditation of study programs. But in the implementation found several problems. The first problem is that the flow of meeting event making is still done conventionally when notifying the meeting agenda by sending SMS to prospective meeting participants. If there are prospective meeting participants who are unable to attend, the meeting participants do not know the contents of the meeting because the meeting material is not accepted by meeting participants who are unable to attend. The absence of a meeting remainder automatically leads to a meeting making prospective meeting participants sometimes forget about meetings. The second problem, namely when making minutes of the meeting is still carried out by each meeting participant. So that many minutes of meetings are not archived and lost. This makes it difficult for the Quality Assurance Unit (UJM) to find minutes of meetings to meet the needs of accreditation or re-accreditation of study programs. The third problem is that during the implementation of the meeting it still involves volunteers from the meeting participants to document the meeting activities with photos or videos, but often the photos or videos are not archived because of forgetfulness. The development of this software is web based using the waterfall method. This system provides a meeting event remainder feature that uses the Google Calendar API. This system uses the Logitech C525 webcam. Unit testing is performed using the white-box testing method 3 times. Validation testing using the black-box testing method 52 times resulted in 100% valid. Usability testing using the System Usability Scale method produces a score of 76.6 which is categorized as acceptable, so that the system meets user needs.

Abstract

The number of traffic accidents is getting more numerous, especially in the time approaching the Lebaran season where people will go home to their villages. Based on data in 2017, there were 73 accidents in the six days before Eid, and when compared to 2016 there were 63 accidents, the number increased quite a lot by 16%. The main factor causing the accident is due to fatigue or drowsiness, because most events are at 21.00-24.00 then followed at 03.00-06.00.. Therefore, we need a system that can detect the state of the driver when he is tired or sleepy. This research developed a drowsiness detection system using Haar Cascade and Convolutional Neural Network. Input to the system is obtained from the Logitech C310 Webcam which will capture an image of a face. The main processing system uses Intel NUC5i7RYH which is used for image processing. The output of the system is the sleepy warning on the monitor when the driver is sleepy and there is an alarm sound for warning. The average accuracy of the system for face detection using Haar Cascade is 100%, the average accuracy for detecting open and closed eyes at a distance of 30-50 cm is 97.23% and the average accuracy for the detection of drowsiness is 97.23%. This system has an average computing time of 0.2075 s which will make it easy to detect drowsiness quickly.

Abstract

Business process which is running well can help the organizations to run their activites effectively and efficiently. In managing the academic administrations, Filkom often had problems such as delays in publishing lecture schedules. In addition, the standard operating procedures (SOP) were not used as a reference for completed the preparations of new semester courses. In this research, the researcher would analyze the lack of SOP and would analyze the root cause of problems to find out the reason why SOP were not implemented and why the publication of lecture schedules were often late. SOP were analyzed based on the completeness, consistency, and realism of the activites. The root causes were analyzed by using root cause analysis (RCA) with 5 whys analysis, after the related business process were modeled with BPMN. After the problems were collected, they were classifie based on the relevant type of waste by using lean concepts to find out the solutions for the next research. The business process of preparations for the new semester need to have indicators of success, so that these problems wouldn't occur for the next time. So, quality factors might be determined by using quality evaluation framework. The results showed that there were the defeciency in the SOP, like the target times of SOP were not realistic with the actual completion time of the activity and there were many naming activities were not clear and consistent. While, the delay in publication of lecture schedules were due to insufficent work time, difficulty in dividing assignments, and limited resources. Wastes were found like activity duplication, overload, waiting, defects, misunderstanding, inappropriate systems, and delay. While the quality factor refered to timeliness and time to recover.
