Abstract

The policy of restricting public activities, which was implemented during the pandemic, had negative effects related to the emotions and mental health of people at various levels. Emotional stability is a proxy indicator in measuring mental health. The pandemic has resulted in various psychological responses, one of which is an emotional response. So it is important to know what emotions are the most dominating in society. Therefore, this research was conducted to inform the community's basic emotions on Twitter social media with the Ekman emotion model, and to implement it with a deep learning algorithm, namely Long Short Term Memory (LSTM) with word embedding FastText. This study succeeded in finding the most dominant basic emotion of society is the category of happy emotions. And based on the model that has been built LSTM-FastText, it produces an accuracy of 99.24% and a loss of 0.0264. This illustrates that very small errors occur in classifying train data. And this model has been well used in analyzing the basic emotions of the community during the COVID-19 pandemic on Twitter social media

Abstract

The growth of Indonesia's tourism sector has contributed significantly to the national economy while increasing environmental pressure through greenhouse gas emissions. Eco-efficiency has become an important concept for assessing tourism sustainability by integrating economic performance with environmental impacts. This study measures the eco- efficiency of the tourism sector across regencies and municipalities in Java in 2023 using the Slack-Based Measure Data Envelopment Analysis (SBM-DEA) model with undesirable outputs and examines its determinants using Tobit regression. Economic performance is represented by tourism Gross Regional Domestic Product (GRDP), while environmental performance is measured by greenhouse gas emissions. The results indicate that most regions remain inefficient, with substantial disparities across areas. Economic development has a significant negative effect on eco-efficiency, whereas infrastructure has a significant positive effect. Education level and urbanization show positive but insignificant effects. These findings highlight the importance of strengthening sustainable infrastructure and cross-sectoral policies to enhance eco- efficient and sustainable tourism development.
