Most studies on sentiment analysis of COVID-19 vaccines on Indonesian social media posts only used one or two classifiers with few modifications. This research investigated sentiment analysis using seven machine learning techniques on Twitter dataset in which the one with the highest evaluation value will be used to predict on other unlabeled Twitter datasets as well as news headlines dataset. The same classifier is also used to build a visualization dashboard that reflect the result of the sentiments. The result from the sentiment classification is then used to identify the topics, by using word cloud. The experiment revealed that SVM classifier has the highest accuracy and micro average F1-measure, which is 84% and 0.76. This classifier managed to capture similar patterns of sentiments in Twitter and news headlines datasets, which is dominated by neutral sentiment. Some of the topics from each sentiment, managed to reflect the real condition when the datasets were collected.","PeriodicalId":250460,"journal":{"name":"2021 International Conference on Informatics, Multimedia, Cyber and Information System (ICIMCIS","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114901964","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}

Since then, Taekwondo has become increasingly popular, and it can be seen when Taekwondo entered the official sport in the XI PON arena in 1985. Due to the popularity of Taekwondo, many instructors have built Taekwondo learning clubs throughout Indonesia. Not only that, the championship for Taekwondo has also increased rapidly in Indonesia. Due to many tournaments that are held, many Taekwondo clubs carry out intensive training to train young athletes to participate in the tournament. Still, the training is considered less than optimal due to the large number of students participating in the training, which makes the instructor pay less attention. To solve the problem, the author has an idea to build an independent learning system using the Pose Estimation method, which is used so that the computer can recognize Taekwondo movements and Multilayer Perceptron with Backpropagation learning which is used to predict Taekwondo movements, By utilizing Pose Estimation and Multilayer Perceptron, machine learning models can be built that can predict Taekwondo movements in real-time which can help Taekwondo students to learn independently from home. This study uses primary data obtained from the DAS (Dynamic Able Success) club, containing two kicks and two blocks.

Thamrin Group Palembang is one of the dealers that sells two-wheeled motor vehicles with the Yamaha brand. Currently, consumer interest in Yamaha Motorcycles is increasing so that it is not uncommon for consumers to have a pivot system to get the Yamaha Motor they want, which is because the available Yamaha Motor unit stock does not meet the buyer's demand. This happened because PT. Thamrin Group Palembang has difficulty in determining the stock needs of Yamaha Motor units for the following years, which is also influenced by sales data that changes from time to time. Therefore, in this study, the trend moment method was applied to be able to determine forecasts or predictions for the future needs of Yamaha motorcycle units. The trend moment method requires sales data from 2 years back and then forecasting calculations are carried out using the formulas from the trend moment method. In addition, as a development of previous research related to the trend moment method, researchers built an information system that can be used to simplify and shorten the time in doing forecasting or prediction calculations. In this study, samples were taken of sales data for the Yamaha Mio M3 125 R from 2019 to 2020 to predict the need for the Yamaha Mio M3 125 R motorcycle unit in January 2021. It can be seen from the results obtained in the manual calculation of the trend moment forecasting that can be displayed on the web-based system that has been built in this research, which shows the prediction results of the needs of the Yamaha Mio M3 125 R motorcycle unit in January. 2021 as many as 26 units.","PeriodicalId":250460,"journal":{"name":"2021 International Conference on Informatics, Multimedia, Cyber and Information System (ICIMCIS","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131562681","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}

Indonesia as the world's largest palm oil producer must be able to group the countries that are priority as the largest importers of palm oil. For this reason, it is necessary to group the countries that are a priority as the largest importer of palm oil.

As it is known that currently there are many people who do not understand the different types of waste to be disposed of, so that even though organic and inorganic types of waste have been provided, people still dispose of waste in inappropriate types. This of course will be very inconvenient in the effort to sort waste in the waste whereas the first place for garbage to gather. Because of the need for a tool that can help the community in distinguishing the types of waste before putting it into the waste with an accurate classification method Based on the problems in classifying the types of waste that have been described previously, we need a system that is able to classify waste according to its type, The MobileNets-V1 architecture is used in this research to classify images. The models generated by the architecture will then be deployed into mobile-based applications. The dataset used in this study consists of 3 classes, namely N (Non-Recyclable), O (Organic), R (Recyclable). Because the data is highly imbalanced, we conduct undersampling in order to balance the data. This undersampling process is done only in the training set after splitting the whole dataset into training, validation, and testing set. After the balancing process, each class has 1822 sample data, totalling of 5466 sample data in the trianing set. The pretrained MobileNets-V1 model is able to classify types of waste very well.
