Abstract
The quality of learning in the classroom is stated to be good if the learning objectives are achieved which is marked by increased student activity and learning outcomes. For that, we need alternative learning strategies that are more effective and efficient, one of which is to use the cooperative learning model type Numbered Heads Together (NHT). This study aims to improve the activity and learning outcomes of physics on wave material through the application of the NHT learning model. The research subjects were students of class XI MIPA3 of SMA Negeri 2 Tembilahan. This research is a classroom action research conducted in 2 cycles. Data collection instruments used were activity observation sheets and written tests of learning outcomes in the form of daily tests with data collection techniques in the form of observations and giving the test. The data analysis technique used is descriptive analysis to determine the extent of increased student activity and learning outcomes by applying the NHT learning model. The results of data analysis obtained an increase in student learning activities in the first cycle from 29.60% increased to 66.40% in the second cycle with a very good category. Improved learning outcomes from 12 students completed with a percentage of 48.00% in the first cycle, to 19 students who completed the second cycle with a percentage of 76.00%. Thus it can be concluded that the use of the NHT learning model can improve the activities and physics learning outcomes of students of class XI MIPA3 in SMA Negeri 2 Tembilahan on wave material.

Summary
Jenis penelitian yang digunakan adalah penelitian tindakan kelas (PTK), dalam rangka memperbaiki mutu proses pembelajaran di kelas, sehingga berfokus pada proses belajar mengajar yang terjadi di kelas (Ningsih, 2016). Instrumen pengumpulan data yang terdiri dari lembar pengamatan aktivitas siswa dan lembar soal tes hasil belajar. Siklus pertama tindakan dilakukan saat proses pembelajaran berlangsung secara teratur sesuai dengan kegiatan pembelajaran pada RPP 1 dengan menerapkan tahapan NHT. Selanjutnya pada siklus kedua, tindakan dilakukan berdasarkan hasil refleksi siklus pertama yang dituangkan dalam RPP 2 dengan pelaksanaan tindakan sesuai dengan tahapan NHT. Instrumen pada penelitian ini adalah instrumen pengumpulan data yang terdiri dari: 1) lembar observasi untuk mengetahui keaktifan siswa yang berisikan tentang kesiapan belajar, interaksi antar siswa dengan guru, interaksi siswa dengan guru, tanggung jawab dan percaya diri, dan 2) tes hasil belajar siswa berupa hasil post test di setiap akhir satu siklus. Teknik analisa data yang digunakan adalah teknik analisis deskriptif, yang di gunakan untuk menganalisis sejauh mana tingkat aktivitas siswa dalam proses pembelajaran pada setiap siklus, memenuhi persamaan (1). Selanjutnya dari hasil penghitungan tersebut dapat dilihat kategori aktivitas siswa berdasarkan pada Tabel 1
