Abstract

ABSTRAKPenelitian ini bertujuan untuk mengetahui nilai emisivitas warna ungu (purple comet), hijau, biru, merah, hijau muda, biru muda, jingga, coklat muda, kuning, merah muda; serta mendeskripsikan peningkatan hasil belajar kognitif siswa dengan menggunakan model PBL pada konsep Perpindahan Kalor siswa kelas X-TKJ SMK Negeri 1 Bengkulu Tengah; dan menjelaskan perbedaan hasil belajar kognitif siswa pada kelompok tinggi, sedang dan rendah. Populasi dalam penelitian ini adalah seluruh siswa kelas X SMK Negeri 1 Bengkulu Tengah tahun pelajaran 2016/2017. Sampel diambil dengan teknik Purpose sampling, yaitu kelas X.TKJ (Teknik Komputer Jaringan) yang diajar dengan model pembelajaran Problem Based Learning (PBL). Penelitian ini adalah penelitian eksperimen semu dengan desain One Group pretest-posttest design. Hasil penelitian menunjukkan: Nilai emisivitas secara berurutan sebesar 0,92; 0,83; 0,75; 0,62; 0,57; 0,54; 0,50; 0,40; 0,31; 0,24; Terdapat peningkatan hasil belajar pada konsep Perpindahan Kalor siswa kelompok tinggi, sedang dan rendah dengan nilai N-gain masing-masing sebesar 0,75 (tinggi), 0,52 (sedang), dan 0,44 (sedang); Terdapat perbedaan hasil belajar kognitif siswa pada kelompok tinggi, sedang dan rendah yang ditunjukkan oleh Fhitung > Ftabel (4,04 > 3,35) pada taraf signifikansi 5%. Kata kunci: Emisivitas warna; miniatur ruang; silinder; media; pembelajaran fisika

Abstract

ABSTRACT            This study aims to: know the value of emissivity of purple, green, blue, red, light green, light blue, orange, yellow, pink, and improvement of learning outcomes by using PBL model on the concept of heat transfer class X TKR SMKN 2 Bengkulu Tengah, and explain the difference of students cognitive learning outcomes in high, medium and low group. This study deals with the measurement of color emissivity and its implementation in physics learning on the topic of heat transfer. The population in this study is all students of class X SMK Negeri 2 Bengkulu Tengah academic year 2016/2017. The sample is taken by purposive sampling technique, that is class X.TKR (Light Vehicle Technique) which is taught by Problem Based Learning (PBL) model. This research is a quasi experimental research with One Group pretest-posttest design. The results showed that the purple comet value was 0.91, the green emissivity (going green) was 0.84, the blue emissivity (true blue) was 0.77, the red color emissivity (talk of the town) 0.66, light green color emissivity (apple martini) of 0.61, blue sky emissivity of 0.54, orange torch emission of 0,50, emissivity of light brown (pastry puff) of 0.46, yellow color emission (absolute yellow) of 0.37, and pink emissivity (crystal pink) of 0.24; There is an increase in learning outcomes on the concept of high, medium and low group high caloric transfer with N-gain values of 0.76 (high), 0.64 (medium), and 0.46 (moderate); There was a difference of students cognitive learning outcomes in the high, medium and low groups shown by Fcount> Ftable (4.40> 3.35) at the 5% significance level.
