The policy entails diverse reactions from the societies, including the citizens in virtual world through their chirps in social media, such as Twitter. Analysis on the social media has proved that it has remarkable potentials to apprehend public opinions on various issues. The opinion analysis was performed to get insights about public perception towards SFH policy. As initially predicted, the result of our analysis would show that the public perceptions towards SFH would be mainly negative. The researcher adopted LSTM model as a deep learning approach. Moreover, implementing the N-Gram extraction technique was able to improve the model’s performance. Model performance accuracy reached 83.30%. It is concluded that the increasing of model accuracy is about 0.018%. While the running time efficiency of LSTM has improved 19.4%. The results of the analysis of SFH’s opinion were 77.90% negative and 22.10% positive.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131016276","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}

These rules have caused many things such as limitation of social interaction and increased limit of public places, including campuses, schools, and other educational institution. This condition leads to the difficulties of educational activities since most classes are either canceled or moved to an online platform. Instead of classes, most of the workshops, conferences, and other activities which are important to students have been canceled or postponed. To alleviate the pandemic impact in education especially for college students this work proposed a system for conduction remote practicum safely and effectively to support the education and experience of these students. Research or practicum is important to preserve student's hands-on experience so that the student's readiness to handle the post-campus job is adequate. In this research, the proposed system architecture enables internet-based remote access of the laboratory equipment via an API with the MQTT communication protocol. The experiment is tested under a three-phase induction motor. The results show that the proposed system has the potential ability to be implemented further in the practicum activity. The average transmission time of 0,388 seconds without the Live Stream feature and 0,679 seconds with the Live Stream feature. Also, the system reliability of the proposed system could reach 98,76 percent.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122931529","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}

For this reason, an assessment of the quality of the clustering results is critical. In general, two essential clustering parameters are the similarities between cluster members in a cluster and the cluster centers’ separation. Various approaches can be used to improve a clustering algorithm’s performance: raw data pre-processing, cluster center initialization techniques, objective function assignment, modification of specific steps, and others. The subject of this study is the pattern of rainfall every month during the year of the observation period obtained from the clustering process. This study aims to improve the performance of K-Mean Clustering through manipulation of raw data pre-processing into certain datasets. Image filtering technique is used to generate a dataset based on the relationship between neighboring rainfall values. Polar-based Cartesian data space transformation is used to generate a dataset based on a range of rainfall values for each month during the year of the observation period. Four scenarios have been used to test the performance of the proposed method. The study results show that the proposed method produces the highest performance ratio (54.79%) of all scenarios’ total average GOS (Global Optimum Solution). Meanwhile, increasing GOS to the original method also resulted in the highest increase in GOS ratio (63.68%) compared to other methods. Further studies will focus on the application of the proposed methods for improving the performance of SOM and Fuzzy C-Mean Clustering.","PeriodicalId":161240,"journal":{"name":"2021 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133725893","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 power sharing method used in this paper is filter based control (FBC). The reference or set point used is power, so the error between the reference power and the actual power is controlled by the proportional controller. In this paper also, to equalize the output voltage of each converter with different input voltages, the PWM signal on the supercapacitor converter is multiplied by the gain. There are 2 scenarios presented to see the performance of the designs that have been made, namely no regenerative braking programmed and with regenerative braking programmed. There are 3 conditions seen in the results of the simulator implementation, namely when starting, deceleration and acceleration to see the performance of the power sharing method used.

Detection by RT-PCR as the gold standard of WHO is still difficult to reach in some areas and has a low sensitivity issue. Many studies have focused on the detection of Covid-19 using computer vision, especially deep learning methods. However, it is necessary to evaluate the preprocessing stage before carrying out the classification to increase the accuracy of its detection. Therefore, the objective of this study was to compare the choice of the CT-Scan image pre-processing method and its effect on the results of covid-19 classification accuracy. The benefit of this study is that it can be used as a recommendation when considering the choice of a CT-Scan image preprocessing method to improve the accuracy of Covid-19 detection through more comprehensive deep learning. This study uses a CT scan image because it is considered to be of better quality than an X-ray image, although the price is relatively more expensive. The various methods used were resizing (deformed and non-deformed), enhancement(HE, CLAHE, EFF), and normalization ranges ([–1 1] and [0 1]). Meanwhile, the deep learning method used is the VGG-16 classifier. The results showed that there was an influence generated by the variations in the preprocessing methods on the precision of the Covid-19 classification. The highest accuracy results were obtained with 88.54% using the deformation ranges of size change, CLAHE improvement and normalization [0 1] and [–1 1].
