Tulungagung Regency has the potential for culinary tourism that can be developed, one of which is traditional culinary. Although the Tulungagung Regency Government has presented a "Halal Culinary Area" and a "Pinka Culinary Tourism Area", the area has not fully provided an interesting visual and functional experience. Therefore, it is necessary to design a space that facilitates traditional culinary MSMEs as well as an educational and recreational place. This design carries the theme of contemporary tropical architecture by considering local climatic conditions, through the application of wide openings, cross ventilation, wide trellises, and the use of natural materials, as well as expressive styles with the shape of a rooster roof and the basic shape of an elliptical building as a symbol of adaptation to climate change and the economy in the business environment. The facilities in this design include traditional restaurants, educational bales, wiyata offices, prayer rooms, playgrounds and other supporting facilities that can attract the interest of the community and introduce traditional Tulungagung culinary.

This study formulates a design concept for the Beach Tourism Resort Area in Botubarani Village by applying tropical architecture that responds to coastal climatic conditions while enhancing the quality of visitor experiences. The research integrates principles of thermal comfort, environmental sustainability, and the ecological potential of coastal environments as the basis for creating climate-adaptive and environmentally responsive tourism areas. The methodology includes site analysis, field observation, climatological assessment, and a literature review related to tropical architecture and coastal tourism design. The collected data were used to determine building orientation, mass layout patterns, visitor capacity, materials, vegetation, and utility systems appropriate for humid tropical climates. The findings show that the site’s position between the sea and the mountains, combined with full-day sun exposure, requires design strategies that maximize cross-ventilation, utilize sloped roofs, provide natural shading, and apply local materials such as wood, bamboo, and red brick. The large spatial needs based on visitor capacity projections are accommodated through a flexible cluster layout that supports visual and functional connectivity between buildings while incorporating green open spaces to enhance microclimate comfort. The utility system is designed using sustainability principles through greywater–blackwater separation, infiltration wells, and recycling-based waste management. This study confirms that the application of tropical architecture in coastal tourism areas can improve thermal comfort, energy efficiency, and environmental sustainability. These findings guide developing tropical tourism area designs that are more adaptive to climate change and more responsive to visitor needs.

This design project is motivated by the low public interest in sports and the limited availability of sports facilities, creating a need for a sports hall that is both effective and efficient in enhancing the community’s quality of life. However, the mere provision of a sports facility is not sufficient; considerations such as building orientation, opening design, and airflow circulation are essential to create an optimal environment for sports activities. Therefore, the tropical architecture approach serves as the primary design basis for the sports hall in Asahan Regency. The aim of this design is to support a healthy lifestyle and improve the quality of life of the local community through comfortable and safe sports activities. The design method adopts a qualitative approach, with data collected through interviews and field observations to understand the needs and preferences of the community. The design also reflects local identity through a mass transformation inspired by the shell form, symbolizing the city of Asahan. The shell structure system is known for its slenderness, making it lightweight and efficient, while its curvature ensures even load distribution. This approach can serve as a model for future sports facility developments in Asahan Regency. This sports hall is expected to become a central hub for athletes in Asahan, providing optimal training facilities to improve their performance. With a modern building and complete facilities, the community can engage in sports activities more comfortably and safely, thus increasing public interest in sports and enhancing overall well-being. This design also aims to promote awareness of the importance of a healthy lifestyle through an effective and efficient sports center.

Sibolga City, located along the seashore and endowed with abundant natural beauty, holds significant potential for development as a marine tourism destination. Beyond its coastal appeal, the city offers opportunities for diverse recreational areas such as camping grounds, botanical gardens, culinary centers, and Mancakrida zones. To support these initiatives, this research investigates the sources of activities and spatial programs that can be realized through the construction of cottages and integrated recreational facilities. Given Sibolga’s hot tropical climate, the application of Tropical Architecture is essential to address environmental challenges including solar exposure, rainfall intensity, air humidity, and wind orientation. This study aims to harness Sibolga’s environmental assets by proposing sustainable cottage designs and recreational spaces that align with the principles of Tropical Architecture. The research contributes to the development of commercial residential models that are harmoniously integrated with nature, promoting economic sustainability and ecological balance. Methodologically, the study involves interviews, site surveys, and comparative analyses to derive contextual design solutions. The final output is a conceptual design for cottages and recreational areas that reflect climate-responsive architecture and support Sibolga’s tourism growth. This research not only enhances architectural knowledge in tropical settings but also offers practical insights for urban planners and stakeholders seeking to revitalize Sibolga City as a vibrant, nature-integrated tourism hub.

The design of Lecturer Housing for Campus 4 Gorontalo State University is a strategic necessity in line with the expansion of educational institutions and the increasing number of educators requiring adequate and proximate housing. The primary objective of this research is to produce a lecturer housing design that is not only adaptive and sustainable, but also harmonized with the Regional Spatial Plan (RTRW) of Bone Bolango Regency. The research methodology encompasses a comprehensive site analysis, examining aspects such as climate conditions, topography, vegetation patterns, infrastructure and utility networks, ambient noise levels, and site accessibility. Furthermore, a zoning and spatial relationship study was conducted to determine effective space allocation based on the principles of tropical architecture and green building practices. The findings of the study highlight that a north-south building orientation significantly reduces heat absorption, while the integration of cross-ventilation strategies enhances natural airflow and thermal comfort. Spatial zoning into public, semi-public, private, and service areas allows for organized layouts and promotes social interaction among residents. Sustainability is reinforced through the application of green architectural technologies, including the use of green concrete, lightweight steel frameworks, solar energy panels, as well as integrated waste-water management systems that separate black water and grey water. Landscaping elements, both softscape and hardscape, are utilized to enhance aesthetics while supporting ecological balance and rainwater absorption. This design proposal contributes to the broader discourse of sustainable tropical housing and may serve as a replicable model for future lecturer housing projects in similar regional contexts. It emphasizes the importance of environmentally responsive, cost-efficient, and socially supportive residential architecture.
