Hiripau Village, inhabited by the Kamoro ethnic community, exhibits housing conditions that do not meet the basic infrastructure standards for livable settlements. This study aims to identify the characteristics of housing facilities and infrastructure, as well as to formulate a development strategy for the area. A qualitative descriptive method was employed, utilizing field observation, in-depth interviews with local residents and traditional leaders, and documentation of existing conditions. The findings indicate that basic infrastructure components such as neighborhood roads, clean water supply, sanitation systems, drainage, and waste management are in inadequate condition. Therefore, the study recommends an integrated planning approach for infrastructure improvement, emphasizing active community participation in the management and maintenance of the residential environment to achieve a habitable and sustainable settlement.

Sentani Kota Village as a strategic area experiences significant pressure due to population growth and economic activities, facing complex problems including the conversion of agricultural land and forests into residential and commercial areas, low public awareness about sustainable spatial planning, and weaknesses in law enforcement and supervision. This condition potentially threatens the environmental sustainability and ecosystem of Lake Sentani. This study aims to evaluate the suitability of spatial utilization in Sentani Kota Village, Sentani District, Jayapura Regency, focusing on two main issues: the level of conformity between existing spatial utilization and the Regional Spatial Plan (RTRW) guidelines, and the factors that support and hinder the effectiveness of RTRW implementation. Conducting overlay analysis of existing conditions and spatial pattern maps, complemented by field verification at 28 observation points and stakeholder interviews with the Spatial Planning Agency. The results show that 76.5% (2,759.07 hectares) of spatial utilization conforms to RTRW guidelines, while 22.9% (825.98 hectares) remains non-conforming, and 0.6% (21.66 hectares) violates regulations. Supporting factors include routine monitoring protocols, high conformity levels in designated areas, firm enforcement actions, and community leadership involvement. Conversely, hindering factors encompass low public compliance, non-conforming zones prone to violations, inconsistent enforcement responses, various types of violations, limited sanction mechanisms, and inadequate preventive measures. This study recommends targeted enforcement in critical zones, transition planning for non-conforming areas, lake buffer zone management, enhanced community participation, and systematic monitoring protocols to achieve more effective spatial utilization control.

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.
