Abstract

Kalkulus Peubah Banyak 2 (KPB 2) merupakan Mata Kuliah Keilmuan dan Keterampilan pada Program Studi Pendidikan Matematika STKIP PGRI Sumatera Barat. Proses perkuliahan masih menggunakan metode ceramah dan hanya mengacu pada 1 buku teks. Karena buku teks yang digunakan sulit dipahami, akibatnya mahasiswa tidak termotivasi untuk belajar mandiri. Oleh karena itu, dikembangkan modul yang mendukung kemandirian mahasiswa dalam belajar dan dapat memberikan kondisi belajar aktif.  Modul  yang  dikembangkan telah  diuji kevalidannya dan  kepraktikalitasannya. Penelitian ini bertujuan untuk menghasilkan modul berbasis masalah yang efektif. Jenis penelitian ini adalah penelitian pengembangan dengan menggunakan model 4-D. Tahap yang telah dilakukan adalah tahap define, design, dan develop berupa validitas dan praktikalitas. Tahap develop yang dilakukan berupa efektivitas yaitu aktivitas belajar mahasiswa. Data dikumpulkan melalui lembar observasi kemudian dianalisis secara kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa modul berbasis masalah untuk perkuliahan KPB 2 efektif karena sudah dapat meningkatkan aktivitas mahasiswa selama perkuliahan KPB 2

Abstract

Latihan fisik terdiri dari aktivitas aerobik dan aktivitas anaerobik. Latihan fisik aerobik maupun anaerobik dapat mengakibatkan pembentukan radikal bebas. Dalam keadaan ini dapat pula terjadi peningkatan sekresi BNP sebagai indikator terjadinya kerusakan otot. Brain Natriuretic Peptide (BNP) adalah Hormon type-B yang diproduksi di otot jantung yang akan terstimulasi ketika ventrikel jantung meregang dan mengalami tekanan yang berlebih atau sebagai sitoproteksi terhadap kelebihan volume dan peningkatan radikal bebas. Sampai saat ini masih relatif terbatas laporan mengenai perbandingan pengaruh latihan fisik aerobik dan anaerobik terhadap kadar BNP di otot jantung dalam melihat pengaruh positih dan negativenya terhadap fungsi jantung. Penelitian ini merupakan studi eksperimental dengan subjek penelitian pada 28 ekor tikus Wistar yang dibagi menjadi 2 kelompok (kelompok pembanding=P1, perlakuan aerobik 1 hari=P2, perlakuan anaerobik 1 hari=P3). Cara perlakuan latihan fisik menggunakan Animal Treadmill, dengan kecepatan 20 meter/menit selama 30 menit untuk latihan fisik aerobik, dan kecepatan 35 meter/menit selama 20 menit untuk latihan fisik anaerobik. Pemeriksaan kadar BNP dilakukan di Laboratorium Biokimia Fakultas Kedokteran Universitas Indonesia. Hasil uji statistik menunjukkan bahwa, tidak terdapat perbedaan yang bermakna kadar BNP otot jantung pada kelompok aerobic dan anaerobik yang diberi perlakuan 1 hari (sesaat). Akan tetapi dari hasil penelitian ini menunjukkan bahwa kadar BNP otot jantung pada latihan fisik anaerobik cenderung lebih tinggi dibandingkan dengan latihan fisik aerobik (6,00±26,13 vs  6,93±10,47) sebagai indikator terjadinya beban yang berlebih pada otot jantung. Dari penelitian ini dapat disimpulkan bahwa untuk memperbiki fungsi jantung, latihan fisik aerobik lebih baik daripada latihan fisik anaerobik.
