Generation Z Perceptions on Blue Space Tourism Role and Stress Reduction at Batu Tunggal Beach, Indonesia

Abstract

Psychological stress among Generation Z has emerged as a growing global concern, driven by academic pressure, digital exposure, and social uncertainty, highlighting the need for preventive approaches beyond clinical interventions. Blue space tourism has gained increasing attention as a nature-based strategy to support mental well-being. This study examines Generation Z’s perceptions of the role of blue space tourism in reducing perceived stress at Batu Tunggal Beach, Indonesia. A cross-sectional online survey was conducted involving 85 Generation Z respondents who had previously visited the site. Perceptions of blue space were measured using a five-point Likert scale encompassing relaxation, natural stimuli, social interaction, revisit intention, and psychological well-being, which were aggregated into a Blue Space Perception Index (BSPI) with strong internal consistency (Cronbach’s α = 0.85). Changes in perceived stress before and after the visit were analyzed using the Wilcoxon Signed-Rank Test, and the association between BSPI and stress reduction was examined using Spearman’s correlation. The results indicate a statistically significant reduction in perceived stress following coastal exposure (p < 0.05), with most respondents reporting lower stress levels after visiting the beach. A positive and marginally significant relationship was also observed between blue space perception and stress reduction (ρ = 0.21), suggesting that higher perceived environmental quality is associated with greater psychological benefits. These findings demonstrate that Batu Tunggal Beach functions as a valuable blue space supporting psychological restoration among Generation Z and underscore the importance of maintaining coastal environmental quality within sustainable tourism development.
