This study analyzes the morphological form and development characteristics of the Petrosea City Park green open space in Mimika Regency, Central Papua. Using qualitative descriptive-analytical methods, this research examines road patterns, spatial configurations, and architectural elements as well as the physical, economic, and socio-cultural characteristics of park development. The results show that the park implements a radial pattern centered on a roundabout with clear hierarchical zoning, integrating Kamoro cultural landmarks through bronze statues. However, infrastructure limitations and underutilized economic potential indicate the need for integrated development to optimize the function of green open spaces in the context of mining cities in Eastern Indonesia.

This study analyzes the impact of sustainable tourism concept implementation on the community of Tobati-Enggros Village, Jayapura City. Using qualitative descriptive methods with in-depth interviews, participatory observation, and document analysis involving 35 informants, this research evaluates three pillars of sustainability: economic, socio-cultural, and environmental aspects. The findings show that sustainable tourism implementation achieves a moderate effectiveness score of 2.7. Economically, tourism creates new employment opportunities and increases community income by 25%-400%, but benefits distribution remains unequal with 70% of profits controlled by 30% of residents. Socio-culturally, tourism helps preserve the unique "Women's Forest" tradition while causing erosion in traditional practices like gotong royong (community cooperation). Environmentally, significant ecosystem degradation occurs with water quality declining 56% and mangrove forest coverage reducing by 10%. The study recommends strengthening community-based tourism institutions, implementing comprehensive waste management systems, and developing community capacity building programs to optimize sustainable tourism benefits while preserving environmental and cultural integrity.
