                <text>COVID-19 is a new disease that has a negatively impacts in Indonesia, so the government is taking several measures to &#13;
suppress the spread of COVID-19, such as new normal, social distancing, health protocols fines, and COVID-19 vaccination. &#13;
The government's handling efforts have reaped a variety of negative to positive responses from the public on social media, so &#13;
this study aims to determine the effectiveness of the government's efforts by analyzing public sentiment using the Deep Learning &#13;
method with 1,875 training datasets consisting of four types government efforts and taken from various media social. The use &#13;
of Deep Learning begins with testing several Deep Learning architectures to determine the best architecture for predicting &#13;
data. The architectures tested include CNN and Bi-LSTM, where from these tests, Bi-LSTM outperforms CNN with the best &#13;
performance achieving the accuracy of 97.34% and 97.33% for precision, recall, and F1-score. The results of public sentiment &#13;
analysis show that social distancing efforts are considered the most effective by obtaining the most positive sentiments by &#13;
33.93%, while the effort to health protocol fines is considered lacking because it obtains the most negative sentiment of 35.64%, &#13;
so the government must continue to enforce social distancing and optimize other efforts that are still considered ineffective</text>

                <text>Indonesian General Analysis Dataset is a dataset sourced from social media twitter by using keywords in the form of &#13;
conjunctions to get a dataset that does not only focus on a particular topic. The use of Indonesian language datasets with &#13;
general topics can be used to test the accuracy of the classification model so as to provide additional reference in choosing the &#13;
right methods and parameters for sentiment analysis. One of the algorithms which in several studies produces the highest level &#13;
of accuracy is naive Bayes which has several variations. This study aims to obtain the method with the best accuracy from the &#13;
naive Bayes variation by setting the minimum and maximum document frequency parameters on the Indonesian General &#13;
Analysis Dataset for sentiment analysis. The naive Bayes classifier variations used include Bernoulli naive Bayes, gaussian &#13;
naive Bayes, complement naive Bayes and multinomial naive Bayes. The research stage begins with downloading the dataset. &#13;
Preprocessing becomes the next stage which consists of tokenizing, stemming, converting abbreviations and eliminating &#13;
conjunctions. In the preprocessed data, feature extraction is carried out by converting the dataset into vectors and applying &#13;
the TF-IDF method before entering the sentiment analysis classification stage. Tests in this study were carried out by applying &#13;
the minimum document frequency (min-df) and maximum document frequency (max-df) for each variation of naive Bayes to &#13;
obtain the appropriate parameters. The test uses k-fold cross validation of the dataset to divide the training data and sentiment &#13;
analysis test data. The next confusion matrix is made to evaluate the level of accuracy</text>

                <text>The spread of Lumpy Skin Disease (LSD) that infects livestock is increasingly widespread in various parts of the world. Early&#13;
detection of the disease’s spread is necessary so that the economic losses caused by LSD are not higher. The use of machine &#13;
learning algorithms to predict the presence of a disease has been carried out, including in the field of animal health. The study &#13;
aims to predict the presence of LSD in an area by utilizing the LSD dataset obtained from Mendeley Data. The number of &#13;
lumpy infected cases is so low that it creates imbalanced data, posing a challenge in training machine learning models. &#13;
Handling the unbalanced data is performed by sampling technique using the Random Under-sampling technique and Synthetic &#13;
Minority Oversampling Technique (SMOTE). The Random Forest classification model was trained on sample data to predict &#13;
cases of lumpy infection. The Random Forest classifier performs very well on both under-sampling and oversampling data. &#13;
Measurement of performance metrics shows that SMOTE has a superior score of 1-2% compared to the use of Random &#13;
Undersampling. Furthermore, Re-call rate, which is the metric we want to maximize in identifying lumpy cases, is superior &#13;
when using SMOTE and has slightly better precision than Random Undersampling. This research only focuses on how to &#13;
balance unbalanced data classes so that the optimization of the model has not been implemented, which creates opportunities &#13;

                <text>Social media such as Twitter has now become very close to society. Twitter users can express current issues, their opinions, &#13;
product reviews, and many other things both positive and negative. Twitter is also used by companies to monitor the assessment &#13;
of their products among the public as insight that will be used to evaluate what aspects of their products need to be further&#13;
developed. Twitter with its limitation of only allowing users to post a maximum tweet of 280 characters will make a lot of &#13;
abbreviated and difficult to understand words used, so it will allow vocabulary mismatch problems to occur. Therefore, in this &#13;
paper, research conducted on aspect-based sentiment analysis of Telkomsel’s products from the aspects of signal and service &#13;
by applying feature expansion using Fasttext word embedding to overcome vocabulary mismatch problem and classification &#13;
with the Support Vector Machine (SVM) method. Sampling technique with Synthetic Minority Oversampling Technique &#13;
(SMOTE) used to overcome data imbalance. The experimental results show that feature expansion can increase the&#13;
performance of model. The final results obtained F1-Score value of the model for the signal aspect increased by 27.91% with &#13;
F1-Score 95.93%, and for the service aspect increased by 42.36% with F1-Score 94.53%.</text>

                <text>In recent years, the application of deep learning methods has become increasingly popular, especially for big data, because &#13;
big data has a very large data size and needs to be predicted accurately. One of the big data is the document text data of &#13;
cancer clinical trials. Clinical trials are studies of human participation in helping people's safety and health. The aim of this &#13;
paper is to classify cancer clinical texts from a public data set. The proposed algorithms are Bidirectional Long Short Term &#13;
Memory (BiLSTM) and Word Embedding Features (WE). This study has contributed to a new classification model for &#13;
documenting clinical trials and increasing the classification performance evaluation. In this study, two experiments work are &#13;
conducted, namely experimental work BiLSTM without WE, and experimental work BiLSTM using WE. The experimental &#13;
results for BiLSTM without WE were accuracy = 86.2; precision = 85.5; recall = 87.3; and F-1 score = 86.4. meanwhile the &#13;
experiment results for BiLSTM using WE stated that the evaluation score showed outstanding performance in text &#13;
classification, especially in clinical trial texts with accuracy = 92,3; precision = 92.2; recall = 92.9; and F-1 score = 92.5</text>

                <text>The pandemic has caused a shift in the tourism industry's drive towards comprehensive digitization. This approach is used to &#13;
prevent the spread of the Covid-19 virus. The impact of Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) limiting the &#13;
mobility of tourists who will vacation in Indonesia causes losses and foreign exchange earnings of the state in the tourism &#13;
industry sector of 20.7 billion. So, to survive in the current situation, industry players must be able to adapt and rise by &#13;
providing more effective innovations. This study aims to develop a Question Answering System or a digital question and answer &#13;
system using a chatbot (ChatterBot). The chatbot is used as an information service provider that can make it easier for tourists &#13;
who are looking for information about tourist attractions. Chatbot-based information service systems can work 24 hours or all &#13;
day, reducing the intensity of direct physical contact with officers and saving operational costs. The chatbot implementation is &#13;
built on the Machine Learning Framework using RASA Open Source with the Python programming language. The knowledge &#13;
base of the chatbot system is trained based on the FAQ (Frequently Asking Question) dataset with a case study of the &#13;
Prambanan Temple tourist attraction as a sample of Indonesian tourism. The results of the evaluation and system performance &#13;
based on data testing obtained the level of model accuracy is 0.91. Furthermore, the weighted average value in the Confusion &#13;
Matrix produces a precision of 0.97, a recall of 0.94, and an F1-score of 0.95. The training and testing model processes locally &#13;
using the Visual Studio Code software</text>

                <text>Depression is a major mood illness that causes patients to experience significant symptoms that interfere with their daily &#13;
activities. As technology has developed, people now frequently express themselves through social media, especially Twitter. &#13;
Twitter is a social media platform that allows users to post tweets and communicate with each other. Therefore, detecting&#13;
depression based on social media can help in early treatment for sufferers before further treatment. This study created a system &#13;
to detect if a person is indicating depression or not based on Depression Anxiety and Stress Scale - 42 (DASS-42) and their &#13;
tweets using the Classification and Regression Tree (CART) method with TF-IDF feature extraction. The results show that the &#13;
most optimal model achieved an accuracy score of 81.25% and an f1 score of 85.71%, which are higher than baseline results &#13;
with an accuracy score of 62.50% and an f1 score of 66.66%. In addition, we found that there were significant effects on &#13;
changing the value of the maximum features in TF-IDF and changing the maximum depth of the tree to the model performance</text>

                <text>The detection of disease in clove plant leaves is generally carried out by diagnosing the symptoms that appear on clove plants. &#13;
This diagnosis is conducted by clove farmers only by relying on their experience or even having to seek information from other &#13;
clove farmers. This is because the agricultural sector has no disease detection system for clove leaves by utilizing digital image &#13;
processing technology to detect diseases in clove leaves. In this study, the researchers applied two methods to make it easier&#13;
for clove farmers to diagnose diseases in their clove plants. Those methods were the imaging system using Gray Level Co�Occurrence Matrix (GLCM) and disease clustering using the K-Means algorithm. The objective of this study was to design and &#13;
build image pattern recognition by utilizing 4 features of the Gray Level Co-Occurrence Matrix (GLCM): energy, entropy, &#13;
homogeneity, and contrast. These 4 features were used to obtain the extraction value from an image. The outcomes were then &#13;
used to cluster the clove plant diseases using the K-Means method. In making the software, the researchers used Javascript, &#13;
HTML, CSS, PHP, and MySql to create a database. The output in this study was an information system application that provides&#13;
disease-type clustering using the K-Means algorithm. The results of the Gray Level Co-occurrence Matrix (GLCM) concerning &#13;
extracting images of clove plant leaves affected by disease indicated that the created system can be used to help clove farmers &#13;
in diagnosing what diseases are infecting their plants by only uploading photos from affected leaves of the clove plant. &#13;
Furthermore, the results of the K-Means calculation on the examined data showed several categories of Anthracnose leaf spot &#13;
diseases. In addition, sample number #40 was included in cluster 2 status, in which the average values for energy, entropy, &#13;
homogeneity, and contrast were 0.583, 0.175, 0.939, and 0.175, respectively</text>

                <text>Pneumonia is an inflammatory lung disease that causes the second largest number of deaths in Indonesia after Dengue &#13;
Hemorrhagic Fever (DHF). In 2021, there was an increase in cases of 7.8% compared to the previous year, and was &#13;
exacerbated by the Covid-19 pandemic. Predictive methods were needed to predict and compare the ARIMA and MLP methods, &#13;
where the results of the best methods were selected for long-term forecasting. The research data used was from January 2014 &#13;
– December 2021, with a total of 96 data. In choosing the best method, the basic error calculations used were Mean Absolute &#13;
Deviation, Mean Squared Error, and Mean Absolute Percentage Error. This study aims to build a predictive model for the next &#13;
period of pneumonia under-five mortality. These results can be used for government policy-making related to mortality &#13;
prevention for the next period. The results showed that the MLP method was superior to ARIMA. Testing 28 mortality rate data &#13;
using the final test result showed that the best method was MLP, with a hidden layer value of 2.2, a learning rate of 0.3, and &#13;
an error percentage of 1.27%. The prediction results of the overall mortality rate of pneumonia under five in 2022 was &#13;
predicted to be 136 people.</text>

                <text>COVID-19 was classified as a pandemic in March 2020, and then in July 2021, this virus had its variance that spreads all over &#13;
the world including Indonesia. The probability of the detrimental of its effect cannot be avoided, because this virus has a huge &#13;
transmission risk during daily activity. To prevent suffering from COVID-19, people certainly need to be vaccinated. In &#13;
responding to its vaccine, the citizen of Indonesia become expressive, so they try to express opinions, for example by uploading &#13;
text on Twitter. Those expressions can be learned using deep learning frameworks which are BERT, CNN-LSTM, and &#13;
IndoBERTweet to get knowledge about negative speech categories such as anxiety, panic, and emotion, or positive speech such &#13;
as vaccines whether worked well. By then, these three methods accomplish in carrying out the prediction of sentiments about &#13;
vaccination using dataset tweets on Twitter from January-2021 to March-2022, for instance using IndoBERT succeeds to &#13;
classify sentiments as positive sentiment at around 80%, and then IndoBERTweet at 68%, in addition using CNN-LSTM reach &#13;
53% with the total of using 2020 dataset from Twitter. According to these results, a lesson learned for continued improvement &#13;
for Indonesia's Government or authorities can be acquired in ending the COVID-19 pandemic</text>
