Social media, particularly Twitter, is a reliable source of information exchange. However, Covid-19 fake news is also being spread by irresponsible people to the public. This fact is so harmful to all parties. Hence, a fake news detector is required to tackle the problem. In this research, a Transformer-based fake news detection system is created. First, an architecture is designed using the Bidirectional Encoder Representations from Transformers (BERT). Three augmentation methods namely spell-checking-based, acronym-based, and typography-based augmentations are then developed to improve the BERT model. A comprehensive examination is performed based on 5-fold cross-validation using eleven thousand Twitter posts with four metrics: Accuracy, Precision, Recall, and F1-Score. Experimental results indicate that those three proposed augmentation methods can increase the BERT's performance detecting fake news related to Covid-19. The acronym-based augmentation gives a low improvement. Next, the spell-checking-based one provides a medium enhancement. Finally, the typography-based one offers the most significant improvement.","PeriodicalId":256184,"journal":{"name":"2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117147337","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 purpose of this paper is to control the output voltage generated by TLBC with the input voltage supplied from FC. In its implementation, the SMC method is used because it is adaptive and nonlinear so it can produce a constant voltage output even though there is a varying voltage from FC. In general, the variation of output voltage from FC caused by V-I characteristics is that the output voltage value will decrease if the output current value increases. Besides that, SMC can also overcome the nonlinear nature of TLBC where the TLBC system works based on switching, so it has different equations with different conditions (on and off). The FC output voltage specification used as the TLBC input voltage is 250V, while the TLBC output voltage is 600V. Research conducted in this paper uses a simulation system with MATLAB/Simulink software in designing the entire system and displays research results in graphic form.","PeriodicalId":256184,"journal":{"name":"2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123429478","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}

EEG-based emotion recognition is a form of research that uses biomedical signals to distinguish a person's psychological condition (without directly paying attention to changes in facial gestures and attitudes). However, there are many studies related to emotion recognition whose classification accuracy is still low and needs to be improved. Therefore, we propose an EEG-based recognition of positive and negative emotions in this study using the Gate Recurrent Unit (GRU) algorithm. EEG data were taken from 38 participants with four recording channels (FP1, FP2, F7, and F8). In EEG recording, a video was played to stimulate the participants' emotions (positive and negative). Then, the EEG data is processed by filtering, artefact removal, frequency band decomposition, feature extraction, and emotion classification based on signal features. Several classification scenarios (such as by varying the activation function of the classifier and the number of EEG channels) are carried out to obtain an optimal level of accuracy. Based on the emotion classification results (using the Softmax activation function) on multi-channel EEG, the accuracy values reached 98.85% (for training) and 91.45% (for testing).","PeriodicalId":256184,"journal":{"name":"2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125345683","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}

In addition to reducing dependence on funds from the Indonesian government, waqf has also had a significant impact on reviving the economy, especially since the outbreak of the COVID-19 virus. The rapid advancement of technology has also transformed waqf, one of which is that people can donate waqf money online through several digital applications. But so far, several advantages and disadvantages are felt by application users. To make it easier to get information based on user experience, we propose to develop a model that can classify sentiments into positive, negative, and neutral automatically. Text classification using word embedding is the basis for getting the best performance results. Bag of Word (BOW) is a word embedding model that is often used, but this model is considered not optimal because it has disadvantages such as dependence on certain languages. Therefore, we suggest the fastText model minimizes dependency on pre-processing words and use 2 classification methods, namely SVM and KNN. This study aims to compare the performance results using the fastText model with conventional models that are often used, namely Bag of Word (BOW) and Term Frequency – Inverse Document Frequency (TF-IDF) to find the best accuracy value produced. Based on this research, it can be interpreted that in general, the fastText model can produce better performance than BOW and TF-IDF.","PeriodicalId":256184,"journal":{"name":"2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE)","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114901158","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 research was conducted in Katingan, Central Kalimantan, as an area of interest. In this case, many human resources do not realize that they are trying to re-utilize the land that was burned by fires in that location. Land that has been burned should be rechecked a few months after the fire to see vegetation density. Using Landsat 8 OLI imagery to detect changes after the fire occurred, this research needs to compare feature extraction to test the level of dryness and humidity in the burnt restoration area. The feature extraction used is Normalized Difference Drought Index for drought detection and the Normalized Difference Moisture Index for detecting post-fire humidity. Furthermore, it will be tested using the Linear Discriminant Analysis algorithm to assess the classification of results from 1 June 2020 - 31 December 2020 in the area of interest carried out. The results of this research obtained for feature extraction NDDI has a lightness level with a range of 0.01 - 0.15 to 0.15 - 0.25, which indicates moderate to a severe drought that occurred in Katingan, Central Kalimantan, with a precision value of 98.33%, Recall 98.33% and Accuracy 98%. While NDMI has humidity in the range of 0.2 to - 0.4 to 0.4 to 0.6, which shows no growth to low growth with a precision value of 68.57%, Recall 68.57% and Accuracy 68% obtained.","PeriodicalId":256184,"journal":{"name":"2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116234938","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}

Sometimes sellers of MSME products need sales recommendations on what is trending among the public. A product recommendation can help users recommend a product that is interesting and needed by that user. Recommendation systems can help users come up with previously unknown or unthinkable information, which can directly aid user knowledge in their search results. In this research, a recommendation system will be built to search for product ideas. This study uses content-based filtering and collaborative filtering methods as well as the TF-IDF algorithm to assist users in recommending the products they are looking for to assist users in finding product-selling ideas they expect. Previous research has examined the recommendation system for Modern Musical Instrument Sales using the Simple Additive Weighing method but has the drawback that the weighting calculation must use fuzzy numbers. Therefore, the content-based and collaborative filtering methods are assisted by the TF-IDF algorithm used in this study to answer these problems. After implementation, we test accuracy by dividing the test data and training data differently. System testing is done by using a confusion matrix. The results that have been tested get an accuracy of 78%. Subsequent research suggests adding MSME product data in recommending product sales ideas to MSMEs so that recommendations are more optimal.","PeriodicalId":256184,"journal":{"name":"2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473521","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}
