This study aims to analyze consumer preferences for fast food restaurants in Indonesia using aspect-based sentiment and emotion analysis. The research data was obtained from Google reviews and questionnaires distributed to 100 respondents. The analysis process includes data cleaning, TF-IDF weighting, and data separation into training and testing sets. Aspect-based sentiment analysis was used to identify positive and negative sentiments on various aspects of the service, while emotion analysis was applied to measure the types and levels of customer emotions based on the detected sentiments. The visualization results show the various sentiments and emotions associated with each aspect of the restaurant's service attributes. In addition, this study used a three-dimensional Importance Performance Analysis (IPA) model to evaluate the relationship between importance and satisfaction levels based on customer sentiments and emotions.  The results of aspect-based sentiment analysis show that most restaurants get positive sentiments on all aspects. The emotion analysis results demonstrate a correlation between any positive sentiment and positive emotions, and vice versa. The findings in this study are expected to provide valuable insights for restaurant managers to improve customer experience through an in-depth understanding of customer sentiments and emotions.

Abstract

Using earphones or earbuds while driving positively and negatively impacts the driver. Congestion is a condition that causes motorists to use these hearing aids. However, the use of hearing aids while driving can threaten the safety of drivers and other drivers. The Bumi Serpong Damai (BSD) area is an area with many motorcyclists, so it can be a reference for motorists to pay attention to the dangers of using earphones while driving. Using earphones while driving, motorcyclists often do not focus on road conditions. Moreover, motorists can be indifferent to signs and other motorists. Therefore, a study was conducted on the use of hearing aids by two-wheeled riders in the BSD area to reveal the underlying problems associated with the use of hearing aids when driving. This study was conducted through the distribution of questionnaires and data processing using the chi-square test and logistic regression. This study aimed to determine motorcyclists’ level of awareness about the dangers of using earphones while driving. The result showed that a relationship exists between the frequency of use and driving comfort; the dominant factor affected by using hearing aids while driving is a reduction in emotions due to traffic jams. This study recommends that the government address traffic congestion due to its strong impact on driver emotions. For motorcyclists, it is advised to keep the earphone volume low to maintain focus on traffic signs and surrounding sounds.

Abstract

ABC Ceramic Factory conducted the process of producing ceramic floor tiles, distributing them to ceramic shops, and then selling them to consumers. Several processes or stages, from manufacturing to distribution, still leave abandoned waste. This research aims to determine what costs in making ceramics at the ABC Ceramic Factory can be reduced to save on company costs. The methods used are Green Quality Function Deployment and AHP Methods. Based on the data processing results, the ceramic manufacturing process is efficient, and the ceramic color is long-lasting because it has the expected satisfaction values of 0.661 and 0.538. Then, recycling waste is the highest technical response, with a value of 0.24. At the same time, the production process is the stage that produces the most waste, with a value of 0.29, and raw material costs are the costs that can be reduced the most, with the highest value of 4+2-. Therefore, the ABC Ceramic Factory must improve from the manufacturing process to the final product.
