Abstract

Problem based learning dibentuk dengan beberapa cara, salah satunya melalui proses pembelajaran matematika. Penelitian ini bertujuan untuk mengetahui tren dan fokus penelitian terkait Problem based learning dalam pembelajaran matematika.Metode yang digunakan adalah analisis bibliometrik. Populasi dari penelitian ini adalah 200 artikel hasil penelusuran data menggunakan aplikasi Publish or Perish (PoP) dari tahun 2017-2023, diperoleh 105 artikel sebagai sampel yang sesuai dengan kriteria kata kunci. Data disimpan dalam bentuk Microsoft Excel sebagai bahan pengolahan data dan disimpan dalam bentuk RIS untuk digunakan pada software VOSviewer untuk mendapatkan pemetaan dalam mencari tren publikasi.

Abstract

The determinant is an arrangement of numbers or symbols in the form of a square and presented between twovertical lines. The determinant as a unit that represents a value from the given matrix. The determinant of matrix A is denoted by [A] or det(A). In matrix theory, the calculation of determinants is one of the studies that is often discussed. Calculation of the determinant associated with a small matrix (n ≤ 3) is usually never a problem, only using the definition of the determinant can usually be solved immediately. However, calculating the determinant of a matrix with a large size is difficult to do if you only use the definition of the determinant. Several methods that can be used to calculate the determinant of a matrix are the row reduction method, theLaplace/cofactor expansion method and the Crout method. To determine the determinant of the matrix in this article, the Crout method will be used.
