The Concept of Transformation on Pandan Mat Weaving Art

Designing the Kelarai pattern is not easy and it is requires mathematical skills to ensure a consistent design. Three key skills are required to produce the Kelarai design which are creatively to shape the pattern, ability to calculate the weave angle and arrange the colours, and efficiency in weaving to ensure that weave overlays are done consistently. In Mathematics, rotation, reflection, and enlargement are types of transformation concept to make some changes in any given geometric shape. In this research, the concept of transformation on pandan mat weaving art at Kolej GENIUS Insan was analysed. The main objective is to determine the pattern of Kelarai Kepala Gajah between the combined transformation Z, followed by Y, X and W that also can be written as transformation WXYZ. Under the combined transformation, Z is defined as an anticlockwise rotation of 90° about the center origin. After rotation, the image formed was reflected using Y and X transformation, which are reflection on line x = 0 and on line y = x, respectively. The transformation W described the final image of Kelarai Kepala Gajah pattern, where the concept of enlargement with scale factor 2 at center of (7, -7) was applied. However, the enlargement with scale factor 2 at center (7, 7) in a single transformation shows the same results as the final image under combined transformation WXYZ. The uniqueness of Kelarai Kepala Gajah pattern can be shown when the final image remains the same for both combined and single transformation were applied.
