Abstract

Tourism is a strategic sector that plays an important role in supporting regional economic development, including in the Special Region of Yogyakarta as one of Indonesia’s leading tourist destinations. High tourism activity has led to an increasing number of visitor reviews on online platforms such as TripAdvisor, which can be utilized to understand tourists’ perceptions and satisfaction levels. The large volume of reviews makes manual analysis ineffective, thus requiring an automated, computation-based approach. This study aims to analyze the sentiment of tourism reviews in Yogyakarta City using the Support Vector Machine (SVM) algorithm with the addition of the Linear Discriminant Analysis (LDA) dimensionality reduction method. The dataset consists of 5,000 tourism reviews that have undergone preprocessing stages, including data cleaning, case folding, tokenization, normalization, stopword removal, and stemming. Text feature representation was performed using the TF-IDF method. Model evaluation was conducted using an 80:20 split between training and testing data, with performance measured using accuracy, precision, recall, and F1-score metrics. The results indicate that the application of LDA to the SVM model improves the balance of classification performance, particularly in precision (77.71%) and F1-score (79.5%), despite a slight decrease in accuracy. Sentiment classification results are dominated by positive sentiment (92.4%), reflecting generally favorable tourist perceptions of destinations in Yogyakarta. This study is expected to serve as a reference for tourism managers in evaluating service quality and facilities based on visitor opinions.

Abstract

This research is motivated by the highly competitive dynamics of the tourism industry in Bali, which demands effective internal coordination. The study aims to analyze the organizational communication climate implemented at Travel Agent Real Bali Holidays, focusing on the aspects of openness, effectiveness, and communication sustainability. The research method used is qualitative descriptive, with data collection techniques through non-participatory observation, semi-structured interviews, and document studies. Research informants were determined using purposive sampling from management, employees across various divisions, and external partners. The results indicate that the organizational communication climate at Real Bali Holidays is flexible and adaptive to operational needs. Communication openness is evident from the space provided for organization members to convey ideas and constraints without rigid structural barriers. Communication effectiveness is supported by the use of integrated communication channels that ensure message clarity and minimize misunderstandings. Communication sustainability is maintained through consistent interaction patterns in daily work activities, although most practices remain informal. These findings emphasize that a conducive communication climate plays a vital role as the foundation for cross-divisional work coordination. The implication of this research is the need to strengthen the communication system through formal procedure standardization to support organizational sustainability amidst industry competition.
