Berdasarkan hasil observasi siswa di kelasVIII dan wawancara dengan kepala Laboratorium IPA fisika diperoleh gambaran bahwa laboratorium disana memiliki alat-alat laboratorium yang cukup memadai namun belum dimanfaatkan secara maksimal. Upaya penyelesaiannya diterapkan pembelajaran berbasis laboratorium, yaitu suatu konsep pembelajaran yang memadukan antara kegiatan praktik dan pembelajaran teori di laboratorium. Tujuannya yaitu untuk mendorong siswa agar selalu aktif dan kreatif dalam menghasilkan keterampilan proses sains yang dimilikinya melalui kegiatan praktikum secara berkelanjutan. Subjek penelitian ini adalah siswa kelas VIII.5 yang terdiri dari 28 siswa. Penelitian ini merupakan penelitian Tindakan Kelas yang berlangsung selama 2 siklus, setiap siklusnya terdiri dari 3 kali pertemuan. Untuk keakuratan data yang diperoleh peneliti dibantu oleh 4 orang observer dalam mengamati keterampilan proses sains siswa dan karakter keaktifan siswa. Berdasarkan hasil penelitian, diperoleh sebanyak 85,71% siswa telah memiliki keterampilan proses sains dengan skor ≥71dan sebanyak 67,86% siswa telah menunjukan karakter keaktifan dengan skor ≥72.

Peta konsep diterapkan untuk memberikan gambaran dan kaitan yang lebih kuat antara konsep statistik yang harus dikuasai calon guru Fisika dalam melakukan kegiatan penelitian. Penelitian ini menggunakan pendekatan kualitatif dengan analisis konten. Hasil Penelitian menunjukkan bahwa calon guru Fisika semester tiga yang mengambil matakuliah stastik untuk pendidikan cenderung menggunakan peta konsep bentuk jaring (net) meskipun didominasi dengan banyak kalimat serta sedikit kata kunci yang digunakan. Pendekatan kuantitatif deskriptif sebaiknya dilakukan pada penelitian berikutnya untuk memberikan perbandingan yang lebih baik dan lebih mendalam mengenai penggunaan peta konsep pada calon guru Fisika. The study aims to provide a qualitative description regarding students’ ability in applying concept map during Statistics for Education classroom. Statistics is known as a challenging subject for pre-service Physics teachers in FMIPA UM. Various lecturing methods have been applied to enhance students’ performance. The concept map applied to describe and integrate the Statistics concepts in Physics education research. The study employed a content analysis in a qualitative approach.

Tangki viskometer kapiler yang dikaitkan ke sensor gaya diisi zat cair untuk kemudian dialirkan keluar melalui pipa kapiler dengan panjang (9,8±0,09)×10-2 m dan diameter dalam (2,1620±0,0096) ×10-3 m. Data penurunan massa zat cair direkam menggunakan sensor gaya buatan Vernier Tecnology dan analisis fitting data menggunakan software Logger Pro. Nilai karakteristik waktu diperoleh dari hasil fitting data digunakan untuk perhitungan koefisien viskositas zat cair menggunakan hukum Hagen-Poiseuille. Dari percobaan ini diperoleh nilai koefisien viskositas air sebesar (1,063±0,113) mPa.s yang sesuai dengan nilai acuan teori yaitu 1,002 mPa.s, oli SAE 10W-30 sebesar (79,01±8,90) Pa.s sesuai dengan nilai acuan teori 76,8 Pa.s, dan gliserin sebesar (593,4±56,7) mPa.s sesuai dengan nilai acuan teori 612 mPa.s. Measurement of liquid viscosity coefficient using Hagen-Poiseuille law with Microcomputer-Based Laboratory method has been done. Viscosity is the fluid declination measure of form changes under sheer pressure. Hagen-Poiseuille law is used in this study because the liquid used is a Newtonian liquid.
