Abstract

Matematika tidak hanya hadir dalam ruang kelas, tetapi juga melekat dalam kehidupan sehari-hari masyarakat melalui aktivitas budaya, salah satunya dalam seni tari. Pendekatan etnomatematika menjadi cara untuk mengungkap keberadaan konsep-konsep matematika yang tersembunyi dalam praktik budaya lokal. Salah satu wujud konkret dari integrasi antara budaya dan matematika dapat ditemukan dalam Tari Lukat, sebuah karya seni kontemporer yang terinspirasi dari ritual tradisional Seblang Olehsari di Banyuwangi. Penelitian ini bertujuan untuk mengetahui etnomatematika pada Tari Lukat karya komunitas seni Damar Art Banyuwangi. Jenis penelitian ini adalah penelitian kualitatif dengan pendekatan etnografi. Metode pengumpulan data yang digunakan adalah observasi, wawancara, dan dokumentasi.  Data yang diperoleh dianalisis melalui tahap reduksi, penyajian data, dan penarikan kesimpulan, sementara keabsahan datanya diuji menggunakan teknik triangulasi metode. Hasil penelitian menunjukkan bahwa terdapat konsep matematika pada Tari Lukat, yaitu bangun datar (segi lima, segitiga, persegi panjang, dan lingkaran), bangun ruang (setengah bola dan bola), bilangan ganjil, sudut lancip, sudut tumpul, sudut lurus, garis horizontal, serta transformasi geometri (refleksi). Selain sebagai struktur fungsional, bentuk-bentuk ini memiliki makna filosofis, yaitu solidaritas, kekuatan, penghormatan, syukur, kebanggaan, dan spiritual lainnya.

Abstract

This purpose of this study was to investigate how well a Problem-Based Learning (PBL) model supported by interactive Student Worksheets (LKPD) affected the tenth-grade students at SMA Negeri 5 Jember’s capacity for mathematical logical thought when studying quadratic equations. The experimental class received a PBL implementation based on interactive LKPD, whereas the control group received traditional instruction. According to the post-test analysis result, the experimental class student’s average score of 87,78 on the mathematical logical thinking ability exam was considerably higher than the control class's score of 74,36. According to the findings of the homogeneity test, tcalculated>ttable with a value of 4.84 > 1.99. Additionally, the experimental class outperformed the control class in the logical thinking indicators, with an overall average of 81.86% in the very high category and 65.03% in the high category. The results support the idea that students’ mathematical logical thinking skill can be enhanced by the use of interactive student worksheets (LKPD) in conjunction with the problem based learning (PBL) approach.

Abstract

Studi mengungkapkan bahwa penerapan gabungan antara model Pembelajaran Berbasis Masalah (PBL) dan pendekatan Teaching at The Right Level (TaRL) memberikan hasil yang efektif, terjadi peningkatan dalam performa belajar siswa. Evaluasi melalui tes diagnostik kognitif mengungkapkan adanya kesenjangan yang nyata antara siswa dengan tingkat pengetahuan tinggi, jika dibandingkan dengan peserta yang pemahamannya terbatas. Perbedaan kemampuan kognitif ini terlihat jelas dan bermakna secara statistik. Hasil observasi terkait budaya belajar siswa ditemukan siswa yang tidak aktif dan tidak memiliki inisiatif mencari tahu mengenai konsep yang masih belum dikuasai, siswa dapat bertanya kepada guru atau teman yang sudah mengerti. Ini menyebabkan hasil belajar yang tidak optimal. Peneliti melakukan tahap merancang, melaksanakan, mengamati, dan merefleksikan di siklus I. Berdasarkan hasil tes diagnostik, siswa diklasifikasikan ke dalam tiga kelompok: tinggi, menengah, dan rendah. Kelompok-kelompok ini, siswa dibagi secara homogen dalam satu kelompok, dengan guru memberikan pendampingan lebih pada kelompok sedang dan rendah. Nilai asesmen siswa naik pada Siklus I, dengan 67% melampaui batas ketuntasan belajar. Setelah penyesuaian modul ajar berdasarkan temuan pada siklus pertama, pelaksanaan siklus kedua memperlihatkan nilai yang meningkat. Sebanyak 86% siswa berhasil mencapai nilai di atas kriteria ketuntasan belajar. Temuan ini membuktikan efektivitas keterpaduan model PBL dengan pendekatan TaRL dalam mengembangkan kemampuan siswa untuk menyelesaikan masalah matematika.

Abstract

The domination number is the number of dominating nodes in a graph that can dominate the surrounding connected nodes with a minimum number of dominating nodes. This domini number is denoted by γ(G). In this research, we will examine the domination number of the distance between two graphs resulting from the shackle operation with any graph as linkage. This differs from previous research, namely the domination of numbers at one and two distances. This study emphasizes how the results of operations on the shackle are connected to the shackle graph as any graph connects the copy. Any graph here means all graphs are connected and generally accepted. The method used in this research is pattern recognition and axiomatic deductive methods. The pattern detection method examines patterns where a graph's number of dominating points can dominate the connected points around it with a minimum number of dominating nodes. Meanwhile, axiomatic deductive is a research method that uses the principles of deductive proof that apply to mathematical logic by using existing axioms or theorems to solve a problem. The Result of graph S_n with t copies and S_m as linkage, then the two-distance domination number in the graph resulting from the shackle operation is γ_2 (Shack(S_n,S_m,t) )=t-1; graph S_n with t copies and C_m as linkage, then the two-distance domination number in the graph resulting from the shackle operation is γ_2 (Shack(S_n,C_m,t) )={■(t,for 3≤m≤6@⌈n/5⌉(t-1),for m≥7)┤; graph C_n with t copies and S_m as linkage, then the two-distance domination number in the graph resulting from the shackle operation isγ_2 (Shack(C_n,S_m,t) )={■(t-1,for n=3@t,for 4≤n≤5@⌈n/5⌉t,for n≥6)┤ This research provides benefits and adds to research results in the field of graph theory specialization of two-distance domination numbers in the result graph of shackle operation with linkage any graph.
