Exploring Ethnomathematics in Batak Toba Carvings for Locally-based Mathematics Teaching Material
No full textSebagai salah satu ornamen adat suku Batak Toba, “gorga” memiliki makna
filosofis dan berfungsi untuk memperindah dekorasi rumah adat. Motif gorga
memiliki ciri khas tersendiri, dengan pola yang tersusun rapat dan desain yang
simetris. Hal ini menunjukkan adanya aspek matematis dalam pola ukiran
gorga tersebut. Penelitian ini bertujuan untuk menganalisis kesimetrian yang
terdapat pada motif gorga yang dapat dimanfaatkan sebagai bahan ajar
matematika berbasis lokal. Kajian dilakukan dengan mengeksplorasi berbagai
motif gorga dan menganalisis jenis simetrinya. Penelitian ini menggunakan
pendekatan penelitian etnografi. Pengumpulan data dilakukan dengan
mengamati bangunan yang berhiaskan motif gorga, mempelajari literatur, dan
melakukan wawancara dengan pemahat gorga. Analisis data kualitatif dapat
dimulai dengan reduksi data, penyajian data, penarikan kesimpulan dan
verifikasi. Hasil penelitian mengungkapkan adanya tujuh jenis simetri yang
diperoleh dari semua motif gorga. Jenis-jenis simetri ini meliputi simetri
translasi, simetri luncuran refleksi, simetri vertikal, simetri rotasi 180°, simetri
vertikal dan rotasi 180°, simetri horizontal, dan simetri vertikal dan horizontal. Kata Kunci :

Gorga, Batak Toba. / As one of the traditional ornaments of the Batak Toba tribe, "gorga" carries philosophical meaning and serves to
embellish the decoration of traditional houses. The gorga motif has its own distinctive characteristics, with closely
arranged patterns and symmetrical designs. This indicates the presence of mathematical aspects within these
carved gorga patterns. This research aims to analyze the symmetries embedded in the gorga motifs that can be
utilized as locally-based mathematics teaching material. The study is conducted by exploring various gorga motifs
and analyzing their types of symmetry. The research is employing an ethnographic research approach. Data is
collected through observing buildings adorned with gorga motifs, studying literature, and conducting interviews with
gorga carvers. Qualitative data analysis can be started with data reduction, data presentation, drawing conclusions
and verification. The research findings reveal the existence of seven types of symmetry obtained from all gorga
motifs. These symmetry types include translation symmetry, glide reflect symmetry, vertical symmetry, rotation 180°
symmetry, vertical and rotation 180° symmetry, horizontal symmetry, and vertical and horizontal symmetry. Keywords:

ANALISIS TOKOH DAN PENOKOHAN DALAM NOVEL TRAUMA KARYA BOY CANDRA
No full textAbstrackThis study aims to describe the analysis of characters and characterizations in the novel Trauma by Boy Candra with a behavioristic psychology which means that changes in behavior as a result of the interaction between stimulus and response. This research uses descriptive method, qualitative research form, and behavioristic psychology approach. The data source in this research is the novel Trauma by Boy Candra. The data in the study are in the form of quotations, words, phrases, and sentences. The data collection technique in this research is a documentary study. Based on the results of data analysis, it can be concluded that. 1) the author describes the main character, namely directly and indirectly. The main characters in the novel Trauma by Boy Candra are Kimara who has a friendly, vindictive, and caring character, 2) the author describes the additional characters in the novel Trauma by Boy Candra, either directly or indirectly. Mother has a caring character, Ardi Sabil has a humble character, Kori Marsandi has a bad- tempered character, Dent Sasindra has a selfish and liar character, Raditio Rahadi has a caring character, Mona has a friendly character, Grandpa has a caring character, and finally the additional character is Putra Marnanda. has a deceitful character. The results of this study can be implemented in learning Indonesian in high school, especially in class XII students in even semesters.Keywords: Behavioristic, Character and Characterizatio
Ethnomathematics Exploration of the Toba Community: Elements of Geometry Transformation Contained in Gorga (Ornament on Bataks House)
No full textGorga is an ornament known to the Batak community. As one of the works of art
that poured in the form of carvings, gorga become icons for batak society. Long before the
Batak people knew formal education, they had made gorga. This is evidenced through several
historical sources. Gorga not only contains the value of art but also has a mathematical
element. There are many mathematical principles used in the process of making gorga. The
principle of geometry transformation is very prominent in the gorga motifs. This article is an
ethnomathematics research that will discuss how the thinking process in making gorga.
Observations and interviews with the gorga craftsmen (pande) are conducted to find out how
the principles of rotation, translation, dilation and reflection are used in making gorga motif

Penerapan Pendekatan Differentiated Instruction dalam Peningkatan Kemampuan Penalaran Matematis Siswa SMA
No full textThis research is based on the problem of low mathematical reasoning ability of high school students. This study aims to examine the improvement of mathematical reasoning ability among students who get Differentiated Instruction approach and conventional learning. The research design was quasi experiment with non-equivalent control group research design using Purposive Sampling technique. Instruments used include mathematical prior knowledge test, mathematical reasoning tests, observation sheets, and interview guides. Quantitative analysis was performed by using t-test and two-way anova test. The result of the research shows that (1) the improvement of student’s mathematical reasoning ability through DI learning is better than conventional learning, (2) The improvement of student’s mathematical reasoning ability through DI learning is better than the students who follow the conventional learning in terms of Mathematical Prior Knowledge.
