Abstract

Penelitian ini bertujuan untuk memperoleh deskripsi kemampuan pemecahan masalah ditinjau dari karakteristik siswa dalam model Problem Based Learning. Anthony Gregorc, dalam DePorter & Hernacki, membagi siswa ke dalam 4 tipe karakteristik cara berpikir antara lain sekuensial konkret, sekuensial abstrak, acak konkret, dan acak abstrak. Subjek penelitian ini adalah 8 siswa kelas VIII SMP Negeri 9 Semarang, yang dipilih dari masing-masing tipe 2 subjek penelitian secara purposive sample. Subjek dalam penelitian ini dipilih dengan mempertimbangkan penjelasan guru mengenai kemampuan siswa mengemukakan pendapat atau jalan pikiran secara lisan. Metode pengumpulan data dalam penelitian ini menggunakan angket karakteristik cara berpikir siswa, tes kemampuan pemecahan masalah, dan wawancara. Analisis data pada penelitian ini dilakukan dengan tahap-tahap yang meliputi reduksi data, penyajian data, dan menarik kesimpulan dan verifikasi. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah siswa dengan karakteristik cara berpikir tipe sekuensial abstrak lebih tinggi daripada siswa dengan karakteristik cara berpikir tipe sekuensial konkret, acak konkret, dan acak abstrak

Penelitian ini membahas mengenai penentuan nilai eigen dominan dan tak dominan suatu matriks dengan metode pangkat (power method). Metode penelitian yang digunakan adalah dengan kajian pustaka. Pada penelitian ini disimpulkan: 1) Nilai eigen dominan suatu matriks A dengan metode pangkat langsung ditentukan dengan langkah-langkah berikut. (i) Menentukan sebarang vektor taknol x0. (ii) Mencari vektor yk = Axk untuk k = 0, dan vektor xk+1 untuk k = 0 yaitu membagi yk dengan λ(k+1), elemen yk dengan nilai mutlak terbesar. (iii) Mencari vektor yk dan xk+1 untuk k dari 1 sampai n hingga λ(k) mendekati λ(k+1). (2) Nilai eigen tak dominan suatu matriks A dengan metode pangkat invers ditentukan dengan mencari nilai eigen dominan A invers dimisalkan λinvers, dan nilai eigen tak dominan A adalah 1 dibagi λinvers. (3) Nilai eigen tak dominan suatu matriks A dengan metode pangkat tergeser ditentukan dengan mencari nilai eigen dominan A yang digeser dimisalkan λshifted dengan nilai geseran s, dan nilai eigen tak dominan A adalah λshifted ditambah s. (4) Nilai eigen dominan suatu matriks A dengan metode pangkat invers tergeser ditentukan dengan mencari nilai eigen dominan A yang diinvers dan digeser dimisalkan λshiftedinvers dengan nilai s dan nilai eigen dominan A adalah 1 dibagi λshiftedinvers ditambah s.
