Transformation of Adat Values Into Benevolence and Conformity in the Traditional House of Limo Koto Kampar Riau, Case Study Ladder to Stair

The customary stilt houses of Limo Koto Kampar Riau transformed their appearance. The result of the transformation from ladder to stair has developed its philosophical roots with Islamic values into a form that is more practical than symbolic. This study identifies the shift in the orientation of values that occurs by tracing the change from one level to the next through the reasons that become the motivations and goals of the residents in developing their houses. Using the Mean End Chain (MEC) method, it indicated that the value orientations that underlie the transformation from the ladder to the stair are Benevolence-Caring and Conformity-Interpersonal, which contain the postulates of Helpful, Family Security, and Respect Parents. It is just one example of how Adat values have transformed into benevolence and conformity in the traditional house of Limo Koto Kampar Riau. This value orientation has not experienced a shift from Islamic values. There is a transformation of form from the philosophical symbol on the ladder to the practical technical ladder. These findings are beneficial for understanding residents' motivations in developing their homes and contributing to addressing the preservation of traditional architecture.
