At Industrial Engineering Universitas Ahmad Dahlan, undergraduate thesis titles are documented by thesis coordinator. The problem is that students are less knowledgeable on thesis topics, so they do not really know the previous students’ thesis topics. Based on the problem, this research aims at developing a program to classify thesis title so the knowledge on the trend of thesis title topic can be got The method used in this research was K-Means clustering, while range measurement method used was cosine similarity. The testing used Silhouette Coefficient method. The phases from text mining were tokenizing, filtering, stemming, similarity, classifying, testing. The result of this research is a program that can process the title data into trend group pattern of thesis title topic.From 138 data obtained, there are three clusters arranged based on the field on Industrial Engineering study program. Silhouette Coefficient testing shows score of 0.5674 that shows the clustering result is classified low. It occurs since the textual data of the thesis title is too widely distributed, so the title has relatively low similarity score","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116815392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

News is not only communicated via the print media, but also through online media. The rapid technology makes people more up to date to on news or current information. Detik.com is one of the online news website that serves a variety of the latest information. Based on the results of questionnaires taken from 30 respondents, the results obtained percentage of 100% which states that online news is important But in detik.com website visitors often get articles that are not in accordance with what is referred to, is evidenced by the results of the percentage is 66.7%. It is claimed that the keywords entered are not relevant to the search results. This research was conducted by applying a weighting method TF-IDF (Term Frequency Inverse Document Frequency). There are several preprocessing stages that conducted in the search for relevance weighting value starting from tokenizing process, Sitering process, stemming process followed by a TF-IDF weighting method. The weighting of the results obtained weight value relevance of each article from highest to lowest weight. This research resulted a web applications Information Retrieval on the site detik.com using TF-IDF weighting method. The test results showed recall value of 1 indicating that the relevant articles can be found by the system and the precision value of 0:50 indicates there are relevant articles that are not found in the system. Recall and precision resulted in a value of 1 if the query (keyword) which included having one term (word).

This research aims to design a low-cost video conference system but with sufficient quality for supporting distant teaching and learning activity.

The results of the evaluation on the central unit show that the video conference application can be executed well in Odroid (50% consumption of CPU usage and 183 MB of memory usage). On the other hand, the results of the evaluation on video conferencing application show that the application can run well under bandwidth of more than 3 Mbps. On network with less than 1 Mbps of bandwidth capacity, the results show that the application can run quite well but with lower performances (higher delays and lower frame rate) with one category on PLR reached the value of 1.714%, exceeding the recommendation of ITU-T with value of 1%.
