Linear programming measures for solving the problem of a linear division of convex multiplayers.

In this research, we are trying to solve Simplex methods which are used for successively improving solution and finding the optimal solution, by using different types of methods Linear, the concept of linear separation is widely used in the study of machine learning, through this study we will find the optimal method to solve by comparing the time consumed by both Quadric and Fisher methods.

Profil Kemampuan Mahasiswa Tadris Matematika dalam Memecahkan Masalah Program Linear Ditinjau dari Perbedaan Tingkat Kemampuan Prasyarat dan Gaya Kognitif Fiel Dependent

This research has been carried out on Semester II students of Mathematics education Department, Faculty of Tarbiyah and Teacher Training at IAIN Palopo in 2017. The type of this research is qualitative descriptive. This research aims to describe the ability of students in solving Linear Program problems in terms of differences in the level of prerequisite ability and cognitive style. The instruments were (1) GEFT test, (2) Linear Algebra prerequisite ability tests, (3) Linear Program problem solving tests, (4) and unstructured task-based interviews. The results of this study are (1) research subjects with high prerequisite ability dependent field cognitive style, showing good ability in understanding problems correctly, planning solutions, solving problems in accordance with the plan and re-examining the results obtained. Subjects can solve Linear Program problems with graph and simplex methods (2) research subjects with prerequisite abilities while field dependent cognitive style, able to understand problems correctly, still unsure when carrying out solutions, but according to plan. Subjects can solve Linear Program problems with graphical methods and simplex methods, (3) research subjects with low prerequisite ability in field dependent cognitive style, lack of ability to understand problems, unable to carry out problem solving correctly, and unsure in explaining the completion steps taken.Abstrak: Penelitian ini dilaksanakan di IAIN Palopo Fakultas Tarbiyah dan Ilmu Pendidikan Tadris Matematika Semester III Tahun 2017. Jenis penelitian ini adalah deskriptif kualitatif. Yang bertujuan mendeskripsikan kemampuan mahasiswa dalam memecahkan masalah Program Linier ditinjau dari perbedaan tingkat kemampuan prasyarat dan gaya kognitif. Instrumen yang digunakan adalah (1) tes GEFT, (2) tes kemampuan prasyarat Aljabar Linier, (3) tes pemecahan masalah Program Linier, (4) dan wawancara berbasis tugas tidak terstruktur. Hasil penelitian ini adalah (1) subjek penelitian dengan kemampuan prasyarat tinggi gaya kognitif field dependen, menunjukkan kemampuan yang baik dalam memahami masalah dengan tepat, merencanakan pemecahan, menyelesaikan masalah sesuai dengan rencana dan memeriksa kembali hasil yang diperoleh. Subjek dapat menyelesaikan masalah Program Linier dengan metode grafik dan simpleks (2) subjek penelitian dengan kemampuan prasyarat sedang gaya kognitif field dependent, dapat memahami masalah dengan tepat, masih kurang yakin saat melaksanakan pemecahan, namun sesuai dengan rencana. Subjek dapat menyelesaikan masalah Program Linier dengan metode grafik dan metode simpleks, (3) subjek penelitian dengan kemampuan prasyarat rendah gaya kognitif field dependent, kurang mampu memahami permasalahan, tidak mampu melaksanakan pemecahan masalah dengan benar, dan tidak yakin dalam menjelaskan langkah-langkah penyelesaian yang ditempuh.
