Abstract

Penelitian ini bertujuan untuk mengetahui optimalisasi pembelajaran daring berbantuan video terhadap peningkatan hasil belajar siswa pada mata pelajaran matematika SMP di masa pandemi covid-19. Jenis Penelitian adalah Penelitian Tindakan Kelas. Subyek dalam penelitian ini adalah siswa kelas XC SMP Negeri 3 Tabanan yang berjumlah 30 orang. Data penelitian dikumpulkan dengan menggunakan tes prestasi belajar dalam program pembelajaran yang dilaksanakan dalam dua siklus. Analisis data dilakukan dengan analisis deskriptif kualitatif. Hasil penelitian menunjukkan bahwa optimalisasi pembelajaran daring berbantuan video pada mata pelajaran matematika di masa pandemi covid-19 dapat meningkatkan hasil belajar siswa. Ini terbukti dari hasil belajar siswa mengalami peningkatan dimana ketuntasan invidu meningkat dari 7 orang (23,33%) pada refleksi awal menjadi 14 orang (46,66%) pada siklus I dan dari 14 orang (46,66 %) pada siklus I menjadi 29 orang (96,66%) pada siklus II. Nilai rerata juga meningkat dari 61,02 pada refleksi awal, kemudian 72 pada siklus I dan meningkat menjadi 83 pada siklus II.

Abstract

Ethnomathematics is a mathematical concept contained in a culture. The presence of mathematics with cultural nuances will make a significant contribution to learning mathematics. One of the ethnomathematics objects in Balinese Hindu culture is the jejahitan which is used as a medium for learning geometry. Jejahitan is a means of praying for traditional Balinese Hindu ceremonies made of young coconut leaves or janur, dried doub palm leaves, with various supporting materials such as flowers and fruit. The jejahitan used in ethnomathematics objects such as taledan, lamak, ituk-ituk, ceniga, tamiang, serembeng daksina, and sampian kapit kacang/canang kojong. At the same time, the applied mathematical concepts (geometry) are square, rectangle, triangle, circle, trapezoid, cylinder, cone, symmetry, width, circumference and volume. Ethnomathematics is very important; apart from being a student learning material, it also serves as a cultural preservation venue.

Abstract

Mathematics and culture are something that cannot be avoided in everyday life. Mathematics and culture are interrelated because mathematics is knowledge humans use to solve everyday problems. In contrast, culture is a complete and comprehensive unity that applies to society. However, sometimes mathematics is seen as outside of everyday life. Ethnomathematics is a mathematical concept that exists in a culture. The presence of mathematics with cultural nuances will make a significant contribution to mathematics learning. One of the ethnomathematics objects in Balinese Hindu culture is the Otonan. Otonan is a birth ceremony carried out by the Balinese people, based on Panca Wara, Sapta Wara, and Wuku in the Balinese calendar system. In determining Otonan, the least common multiple of the numbers 5, 7, 30 and repeated (cycles) are calculated so that the count for the Otonan ceremony is held every 210 days. Meanwhile, in determining Panca Wara, Sapta Wara and Wuku in Otonan, modulo (mod) numbers are used, namely modulo 5, modulo 7 and modulo 30. Ethnomathematics is very important; apart from being a learning material for students, it also functions as a means of cultural preservation.
