Abstract

The purpose of this study was to improve the quality of learning in the classroom, especially the basic movements of students by using a baseball game. This study uses classroom action research methodology. The population of this study was the entire fifth grade of SDN Ketintang 1 Surabaya as many as 26 people. The sample used cluster random sampling. This study will take 3 data needed by researchers, cognitive, affective, and psychomotor domains. The results of cycle 1 show the average value of both cognitive, affective, and psychomotor with varying average values. The average cognitive pretest 50 and posttest 80, there is a significant increase after being given treatment with a good predicate. For affective obtained an average score of 80 with a good predicate. The average student psychomotor 76 with a very good category but there are some students who still have not reached the minimum criteria of the assessment. Cycle 2 obtained an average in the pretest and posttest cognitive domain of 76 and 83, and for the affective domain obtained an average score of 85. For the psychomotor domain obtained an average score of 87. So that with the completion of a significant increase in the items and also the completeness carried out by students, it can be concluded that increasing students' basic movements through the inscription game can successfully improve students' knowledge, students' attitudes, and students' basic movements.

Abstract

Styrofoam kini semakin banyak digunakan untuk berbagai keperluan, seperti pengaman elektronik dan wadah makanan. Banyaknya tumpukan styrofoam dikarenakan styrofoam merupakan limbah yang sangat sulit terurai di alam. Banyaknya tumpukan styrofoam dikarenakan styrofoam merupakan limbah yang sangat sulit terurai di alam. Sehingga perlu dilakukan penelitian untuk mengurangi limbah styrofoam di alam, seperti penggunaan styrofoam sebagai bahan tambah dalam campuran aspal Pen 60/70 yang menghasilkan aspal modifikasi. Tujuan penelitian ini untuk mengetahui pengaruh penambahan styrofoam terhadap nilai pemeriksaan aspal dan nilai karakteristik Marshall. Penelitian ini menggunakan metode eksperimental yang dilakukan di Laboratorium Perkerasan Jalan Raya, Fakultas Teknik, Universitas Sebelas Maret. Kadar styrofoam yang digunakan 1,5% dari berat aspal, kemudian dibandingkan dengan aspal penetrasi 60/70. Variasi kadar aspal yang dipakai adalah 4,5%, 5,0%, 5,5%, 6,0% dan 6,5%. Benda uji yang digunakan berjumlah masing-masing 3 buah dari setiap variasi kadar aspal. Pengujian menggunakan alat uji pemeriksaan aspal dan alat uji Marshall test. Data hasil uji digunakan untuk mendapatkan nilai perbandingan antara aspal penetrasi 60/70 dengan aspal modifikasi.
