Abstract

Flooding is a natural phenomenon in Bulungan that can affect the discomfort of people's living conditions. Floating house technology has the potential to be a flood mitigation strategy in Bulungan Regency, North Kalimantan. Through the study of Floating Architecture technology, including floating houses, raft houses with plastic drums and houses made of EPS (Expanded Polystyrene) material. This research explores the use of this technology in the context of flood mitigation in the Bulungan district. Analyzing various sources of information, this research identified 3 (three) potential technologies. This research is limited in being able to identify technologies that have the potential to be applied. Each of these technologies has similarities that have the potential to be applied as flood mitigation in Bulungan Regency, looking at aspects such as the Bulungan floating house concept, security and sustainability efforts.

Abstract

This study investigates the material circularity of modular wall panel designs using bamboo, wood, and light-gauge steel (LGS) as primary components. Through a comparative analysis of 9 representative panel prototypes, the research evaluates embodied energy (EE), recycling efficiency, and percentage of discarded material under a cradle-to-gate perspective to assess environmental performance. The study examines the relative circularity performance of bamboo, wood, and steel-framed panels. Furthermore, the research examined material configurations that best balance structural function and circularity. Key limitations include the modest sample size (9 prototypes), the educational provenance of prototypes (course-based fabrication), reliance on cradle-to-gate accounting rather than full life-cycle cost or in-service performance data, and uncertainty ranges in embodied-energy databases. Results indicate that biologically composed panels, such as bamboo and wood, demonstrate significantly lower EE and negligible discarded waste, aligning well with circular economy principles. These caveats are discussed and used to frame recommendations for further LCA, long-term performance testing, and scaled prototyping.
