<![CDATA[Kemampuan mahasiswa dalam memecahkan masalah masih sangat kurang. Tujuan penelitian ini untuk meningkatkan kemampuan pemecahan masalah (KPM) mahasiswa melalui pembelajaran berbasis masalah dengan bantuan lembar kerja mahasiswa (LKM). Jenis penelitian yang digunakan melalui pendekatan yakni penelitian tindakan kelas dengan 2 siklus. Objek penelitian adalah mahasiswa Diploma tingkat 1 Institut Teknologi Del yang berjumlah 120 Mahasiswa TA. 2020/2021 pada mata kuliah Matematika Diskrit. Data penelitian dikumpulkan melalui tes dan dianalisis melalui peningkatan analisis gain serta dilakukan wawancara dan kuesioner. Hasil penelitian didapat bahwa ketuntasan belajar terjadi sebesar 66,80% dan peningkatan rata-rata KPM 19,47% dengan nilai gain 0,37 (sedang). Hal ini menunjukkan bahwa terjadi peningkatan KPM mahasiswa dengan menggunakan model pembelajaran berbasis masalah dan bantuan LKM dapat tercapai secara optimal. Hasil wawancara dan kuesioner mengatakan bahwa konten soal sangat baik dan memberikan pengaruh pemahaman materi yang cenderung lebih baik. The ability of students to solve problems is still very lacking. The purpose of this study was to improve student problem solving skills (KPM) through problem-based learning with the help of student worksheets (LKM). The type of research used through the approach of classroom action research with 2 cycles. The object of the research is Diploma level 1 Del Institute of Technology students, totaling 120 TA students. 2020/2021 in the Discrete Mathematics course. Research data were collected through tests and analyzed through increased gain analysis and interviews and questionnaires were conducted. The results showed that the mastery of learning occurred by 66.80% and the average increase in KPM was 19.47% with a gain value of 0.37 (medium). This shows that there is an increase in student learning outcomes by using problem-based learning models and LKM assistance can be achieved optimally. The results of interviews and questionnaires said that the content of the questions was very good and influenced the understanding of the material which tended to be better.]]>
