Abstract

So far, education in Indonesia is still dominated by teacher oriented classroom as main source of knowledge, so that teachers often ignore student’s initial knowledge. The application of CTL learning is expected to influence students’ rational thinking activities and skills. Based on this background, the researcher conducts a research to find out the correlation between activities and student’s rational thinking skill in CTL learning. The objective of this research is to identify the correlation between activities and student’s rational thinking skill in CTL learning. This research was conducted in Bina Mulya Senior High School in Bandar Lampung by using one experiment classroom (classroom X2) with 39 students as samples. Teacher observed the students’ learning activities when the learning process is taking place. After three times of meeting by using CTL learning, tests for rational thinking skill were conducted by using student’ rational thinking problems that were subsequently processed with correlation tests. The results show that there is a positive and significant correlation between activity and student’s rational thinking skill, and the correlation is strong and it is indicated by value of rcount of 0.756.Keywords: activity, student’s rational thinking skill, CTL learning

Abstract

ABSTRAK Tujuan penelitian ini adalah 1).Untuk mengetahui prosedur pembuatan baglog di Kota Medan. 2).Untuk menganalisis kelayakan usaha baglog jamur tiram di Kota Medan. Metode penelitian yang digunakan adalah studi kasus, dengan penentuan lokasi penelitian secara purposive yaitu pada Usaha Jamur Mushroom House dan Koptan Jamur Tiram, dengan metode analisis yang digunakan berupa analisis kuantitatif deskriptif. Untuk menganalisis rumusan masalah menggunakan analisis biaya produksi dan studi kelayakan usaha baglog jamur tiram R/C. Berdasarkan hasil dari penelitian 1). Proses pembuatan baglog dimulai dari bahan baku media tanam yaitu serbuk kayu gergaji 100 kg, bekatul 10 kg, kapur pertanian (kaptan). Semua bahan dicampurkan sambil ditambahkan air. Banyaknya air disesuaikan hingga medium kompak yaitu ketika dikepal tidak terurai dan ketika diperas tidak mengeluarkan air. Sebanyak 0,5 kg medium selanjutnya dimasukkan ke dalam plastik tahan panas ukuran 1 kg kemudian padatkan dan ditutup dengan mengikatnya menggunakan karet sambil menyelipkan kapas/kapuk pada bagian atas. Sterilisasi selama tidak kurang dari 5 jam. Setelah steril, simpan baglog di tempat yang bersih. 2) usaha baglog jamur tiram di Mushroom House layak diusahakan dengan R/C sebesar 1,71>1 dan Koptan Jamur Tiram juga layak diusahakan dengan R/C sebesar 2.17>1, Sehingga dapat disimpulkan usaha baglog di kedua lokasi usaha layak untuk di usahakan
