Floating Houses Organized By: Supported By: 2 METHOD The method used in this research is qualitative. This research uses a case study approach The location of this research is a number of Rumah Lanting located alongside the Melawi River in Sintang Regency of West Kalimantan Province. This study aims to identify the adaptations that occur in the floating house due to changes in the environmental conditions. The variables used are active and passive adaptations. Figure 4.

Number of Occupants and Duration of Stay in Rumah Lanting adaptations to achieve the comfort of living in the floating house have occurred in the early days of occupying the floating house. The characteristics of the floating house are analyzed by looking at the inner and outer spatial layout patterns. The spatial layout in the floating house is arranged with a centralized approach. The outdoor layout of the floating house is closely related to the relationship between the inner space and the surrounding environment. Organized By: Supported By: 4 Figure 6. (a) Floor Plan; (b) Organizational Space; (c) Living Room FINDINGS AND DISCUSSION On this Melawi river, there are several Rumah Lanting which are affected the tides of the river. These houses have experienced this condition since the occupants began the settlement. It regularly occurs throughout the year and has become a habit for the occupants of these Rumah Lanting to respond to it. Organized By: Supported By: 5 Figure 7.

Active Adaptation Process Active adaptation means that the role of the individual is very important in influencing the environment Passive adaptation places the floating house as an object that makes changes. Changes that occur in the floating house are an attempt to adapt to changes in the environmental conditions. Organized By: Supported By: Figure 9. Passive Adaptation Process 6 CONCLUSIONS • The occupants of the floating house have made an adaptation process for a long time according to the length of their stay in the house. • The floating house is a house that has a multi-functional space so that the activities it accommodates vary. Various activities accommodated do not hinder the adaptation process, and the changes that occur do not significantly change the physical building. • Active adaptations are the occupants’ response to adapt to changes in the environmental conditions. The changes involve activity patterns, territory and privacy. • Passive Adaptations are made by making adjustments and changes to the floating house. The changes include position, orientation, access and function. Organized By: Supported By: 7 REFERENCES • Clark, J. K., McChesney, R., Munroe, D. K., and Irwin, E. G.
