Abstract

Siak weaving is a work of art resulting from the manufacture of songket cloth by craftsmen in Siak Sri Indrapura, Riau Province. This fabric has a variety of motifs, displaying the characteristics of Riau Malay culture. The motifs on Siak woven fabrics are generally taken from the natural environment, such as plants, animals, and other natural objects, which are then twisted (transformed) into interesting motifs, arranged systematically that form geometric patterns. Descriptive qualitative research was conducted, by collecting data and information related to Siak woven motifs through observation and interviews with parties at the Siak woven fabric production center. Identification is carried out on all existing Siak woven fabric motifs to find out whether there is an application of geometric transformation in these woven fabric motifs. From the results of observation and identification, as many as 58 types of motifs were obtained in siak weaving. If observed carefully, the pattern of the arrangement of the motifs of the fabric, there are actually rhythmic and patterned properties of regularity.  Some forms of regularity patterns on Siak woven fabrics are applications of geometric transformations. Some are in the form of reflection, rotation, translation, and dilatation.

Abstract

Tenun siak merupakan karya seni hasil pembuatan kain songket di Siak Sri Indrapura Provinsi Riau yang memiliki motif menarik dan variatif dengan ciri khas Melayu Riau. Motif tersebut diambil dari lingkungan yaitu flora, fauna dan alam lainnya, kemudian dikembangkan dan disusun secara sistematis membentuk pola geometris tertentu. Penelitian pendahuluan deskriptif dilakukan dengan menggunakan referensi literatur, pengumpulan data dengan wawancara dan observasi ke tempat pengrajin tenun Siak, mengidentifikasi semua motif yang ada untuk mencari jawaban apakah motif tersebut tersusun membentuk pola kelompok frieza, pola yang dibangun dengan penerjemahan dalam satu arah, selain isometri lainnya berupa pantulan horizontal, pantulan vertikal dan rotasi atau luncuran 180°. Setelah dilakukan observasi dan identifikasi, diperoleh 58 jenis motif pada kain tenun Siak. Dari keseluruhan motif diketahui bahwa semuanya membentuk pola frieze. Ada yang membentuk pola freeze F1, F2, F3 hingga pola freeze F7. Terkadang selembar kain tenun Siak dibuat dari kombinasi beberapa pola dekorasi. Sejauh ini belum ditemukan motif tenun Siak yang tidak membentuk pola frieze. Hal ini menunjukkan bahwa masyarakat Siak, telah lama menggunakan ide-ide matematis dalam pengembangan motif tenun Siak. Selain itu, penggunaan etnomatematika tenun Siak merupakan langkah yang tepat untuk meningkatkan literasi matematis siswa.

Abstract

This study aims to determine the effect of the Ethnomathematics-Based Problem-Based Learning (PBL) model on the numeracy skills of 8th-grade students at SMP Negeri 15 Pekanbaru. The research employs a quasi-experimental design with a pretest-posttest control group. The sample consists of two classes selected through random sampling: an experimental class taught using the ethnomathematics-based PBL model and a control class taught using conventional learning methods. After conducting the normality test, the post-test significance value for the control class was found to be 0.004, which is smaller than the significance level of 0.05 (0.004 < 0.05). Thus, the data are not normally distributed. Since one of the datasets is not normally distributed, a non-parametric Mann-Whitney U test was performed. The test results show an Asymp. Sig. (2-tailed) value of 0.000, which is smaller than the significance level of 0.05 (0.000 < 0.05). Therefore, H1 is accepted, and H0 is rejected. This indicates a difference in the average numeracy skills between the experimental class and the control class. In other words, the average numeracy skills of students using the Ethnomathematics-Based Problem-Based Learning (PBL) model are better than those of students using the conventional learning model. Hence, the ethnomathematics-based Problem-Based Learning (PBL) model positively impacts the numeracy skills of 8th-grade students at SMP Negeri 15 Pekanbaru.
