Abstract

This study examines consumer preferences for Apple and Samsung flagship smartphones in Surabaya by applying choice-based conjoint analysis in a realistic multi-attribute choice setting. The research focuses on six attributes that are highly relevant in the premium smartphone market based on expert judgement justification. The study identifies the most preferred product configuration based on estimated utility value, the relative importance of each attribute, and market preference simulation using Lighthouse Studio by Sawtooth Software. The findings indicate that respondents tend to prefer an Apple brand smartphone offered at a lower price range, with larger internal memory, a higher-resolution main camera, a larger battery, and cashback promotion. The results also show that brand and price are the dominant determinants of preference. In addition, the market simulation suggests that a more balanced product concept can outperform the newer or premium alternatives when consumers evaluate trade-offs simultaneously.

Abstract

he Room Occupancy Rate (TPK) of starred and non-starred hotels in Bali Province in the period March 2024 to March 2025 was recorded at 52.71% while non-starred hotels were at 38.44%. This percentage experienced a significant increase in October 2024, where the ROC for starred hotels reached 64.37% and for non-starred hotels 43.94%. This increase indicates post-pandemic recovery and increased tourist interest during the peak season. However, in 2025, the ROC experienced a gradual decline. In February 2025, the estimated ROC for starred hotels showed a figure of ±51.62% and for non-starred hotels ±36.35%, then decreased again in March 2025 to 46.61% for starred hotels and 35.71% for non- starred hotels. This decline shows that even though Bali's hotel industry has recovered, maintaining occupancy levels remains a challenge, especially outside the holiday season. Consumer expectations of digital services and information when choosing accommodations can be one of the causes of these fluctuations. This study aims to examine and analyze the influence of user-generated content (UGC) and electronic word of mouth (E-WOM) on purchasing decisions through brand image as a mediating variable. The analysis method carried out quantitatively by distributing questionnaires which then be analyzed using the Structural Equation Model (SEM). The results of this study indicate that User-Generated Content (UGC), Electronic Word of Mouth (E-WOM), and Brand Image have a positive but insignificant effect on purchase decisions. Furthermore, User-Generated Content (UGC) and Electronic Word of Mouth (E-WOM) have a positive and significant effect on Brand Image. Additionally, User- Generated Content (UGC) and Electronic Word of Mouth (E- WOM) have a positive and significant indirect effect on purchase decisions through Brand Image as a mediating variable.
