The antenna which is configured in a planar array is designed on 2 layers of FR4 epoxy dielectric substrate. On top side of the first layer, 8 square patch antennas workable at the frequency of 2.4 GHz are circularly configured and fed using a microstrip feeding line based on proximity coupling technique. The microstrip feeding line is printed on top side of the second layer, while the groundplane which takes a circular shape is placed on bottom side of the second layer. PIN diodes with the type of SMP1345-079LF are connected at the end of microstrip feeding lines to modify the radiation pattern of array antenna. When 2 antennas positioned across each other are set to be active, the measured reflection coefficient is –14.39 dB at frequency of 2.4 GHz. In addition, the antenna has and the measured gain of 0.25 dBi and –10 dB working bandwidth of 240 MHz ranges from the frequency of 2.32 GHz to 2.56 GHz.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"1 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":"130284724","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}

The assignment of a course is charged at 20% of the final assessment of a course. Each lecturer has an average of 40 students in each class, while the lecturer can teach more than one class of courses. The large number of students will make the number of assignments too large because the ratio of the number of lecturers and students is very different. This is a burden on the lecturer because it has the responsibility to check each of student work assignments. The level of similarity of course assignments is one of the ways lecturers can assess a subject's assignment. This study aims to help lecturers detect the similarity of student tasks by using a task similarity detection system. This study uses Rocchio method to detect the similarity of words. The type of document tested is formatted in .pdf. The language used in the course is Indonesian. The preprocessing stages in this research consists of Case Folding, Tokenizing, Filtering, Sorting. The TF.IDF uses as the word weighting and the similarity measurement with the Rocchio method so that it gets the percentage value of the similarity between documents. The development stage started from planning, analysis, design, implementation and testing. The testing stage including testing with dummy data and usability data. Based on the research that has been done, the Rocchio method can classify documents that are similar to the results of the accuracy of 74,6% and detection errors from the similarity of queries with documents of 2.54 or 25.4%.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"1 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":"130173798","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}

This disease occurs when there is atherosclerosis (fat deposits) that block the flow of blood to the heart muscle in the coronary arteries. The gold standard method that doctors refer to diagnose coronary heart disease is coronary angiography. However, this method is invasive, high risk, expensive and sometimes the diagnosis result is not accurate. The purpose of this research is to perform diagnosis of coronary heart disease based on computer. Diagnosis of coronary heart disease based on computer will be done with data mining methods rules, based on Cleveland dataset. In this research, feature selection method based on computer and medical expert used are Variable Precision Rough Set (VPRS) and Motivated Feature Selection (MTF). The classification for diagnosis used data mining methods based on rules are VPRS and Repeated Incremental Pruning Error Reduction (RIPPER). The methods are chosen to observe the simplest pattern of features and rules knowledge from big data, imprecise and ambiguous data. The proposed method is evaluated on Cleveland coronary heart disease dataset taken from the UCI repository. The feature selection VPRS and the combination classifier VPRS dan RIPPER obtains the best evaluation result with accuravy achieved of 88,88889%. While the accuracy of VPRS and RIPPER have the same values is 84,84848%.

An FR4 epoxy dielectric substrate is one of the materials which is frequently used to implement the microstrip patch antenna. This paper presents a performance analysis of microstrip circular patch antenna composed of artificial dielectric material (ADM). Here, the ADM is made of an FR4 epoxy dielectric substrate as the host material which is modified by incorporating a number of thin conductor wires into inside of the dielectric substrate. Meanwhile, a conventional microstrip circular patch antenna is also designed as comparison by using the same dielectric substrate without any modification. The characterization results show that the resonant frequency of microstrip circular patch antennas made of ADM with 82 and 110 thin conductor wires are 16.19% and 23.17% lower than of the conventional microstrip circular patch antenna, respectively. Whilst the–10dB working bandwidths of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are around 72.9MHz narrower around 43.4% than of the conventional microstrip circular patch antenna. In addition, the gains of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are 5.54dBi and 6.1dBi, respectively, where these are relatively higher than of the conventional microstrip circular patch antenna which has the gain of 5.24dBi.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"228 2 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":"124501741","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}
