Abstract

Ensemble learning is one of machine learning method that can solve performance measurement problem. Standalone classifiers often show a poor performance result, thus why combining them with ensemble methods can improve their performance scores. Ensemble learning has several methods, in this study, three methods of ensemble learning are compared with standalone classifiers of support vector machine, Naïve Bayes, and decision tree. bagging, AdaBoost, and voting are the ensemble methods that are combined then compared to standalone classifiers. From 1670 dataset of twitter mentions about tourist’s attraction, ensemble methods did not show a specific improvement in accuracy and precision measurement since it generated the same result as decision tree as standalone classifier. Bagging method showed a significant development in recall, f-measure, and area under curve (AUC) measurement. For overall performance, decision tree as standalone classifier and decision tree with AdaBoost method have the highest score for accuracy and precision measurements, meanwhile support vector machine with bagging method has the highest score for recall, f-measure, and AUC.

Abstract

This research investigated how occupations  influenced on stress and behaviors at work using questionnaire surveys (N = 613). Four heterogeneous occupations were recruited, including high school teachers, shop clerks, factory employees and civil servants. Civil servants reported more sources of pressures, shop clerks  reported higher levels of work strain, factory employees reported lower occurrence of absence behavior, and high school teachers reported lower intention of quitting job and higher working morale. The differences in stress and work behaviors across four occupations were due to two major factors. First, occupational differences, i.e., uniqueness and culture within the occupation. Second, individual demographics, i.e., marital status, education, job tenure, position rank and age. These individual demographics also offered account of differences in absence behavior,  intention of quitting job and low working morale across four occupations. Implications of the findings and suggestion for future research are discussed.  Keywords: occupation, stress and work behavior

Abstract

Lesbian, gay, Bisexual, and Transgender (LGBT) is an individual who has a sexual orientation or gender identity that is different from the heterosexual majority. The LGBT community now dares to appear openly on social media; nowadays, social media is used as a source of information and a place to provide comments. The Indonesian state generally still views the LGBT community as deviant behavior. This research was conducted to understand Indonesian society's views on LGBT through YouTube and social media. The text mining method analyzes and classifies the counter or pro sentences expressed in the comments. The model used in this research is IndoBERT because the research object studied is Indonesian. IndoBERT is part of the Bidirectional Encoder Representation From Transformers (BERT) model. The data sources used were 1,493 data. The stages carried out in this research included the preprocessing stage, which included case folding, data cleaning, tokenization, stopword removal, stemming, and normalization, then the data labeling stage, and finally, the model building stage with IndoBERT Fine Tuning. The level of accuracy achieved using IndoBERT is 74%.
