Abstract

The purpose of this research is to describe the difference of student’s achievement cognitive, affective, and psychomotor on natural science subject between cooperative learning model with kancing gemerincing type and time token type. Which one’s better, the student’s cognitive, affective, and psychomotor on environment pollution   concept between cooperative learning model with kancing gemerincing type and time token type. This research used pre experimental design method, which is the population is all of the seventh  grade students of SMP Negeri 8 Tasikmalaya. Sample total entire 2 class that is class VIIA and VIID with each student as much 35 person. Measurement uses post test. Analysis technique that used t-independent on level of significant α = 0,05. The result shows that found the difference of student’s achievement cognitive, affective, and psychomotor on environment pollution concept between cooperative learning model with kancing gemerincing type and time token type. Based on the result in above it can be said student’s achievement cognitive, and psychomotor by using kancing gemerincing type model was better than time token type model on environment pollution concept. Beside that student’s achievement affective by using time token type model was better than kancing gemerincing type model on environment pollution concept.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh konsentrasi M-Bio terhadap kecepatan pengomposan sampah sayur pasar. Metode penelitian yang digunakan adalah deskriptif kualitatif, penelitian dilakukan di Laboratorium Botani Jurusan Pendidikan Biologi FKIP Unsil selama empat bulan dari mulai persiapan sampai diperoleh kompos. Bahan yang digunakan dalam penelitian adalah sampah sayur pasar, dengan instrument berupa pedoman observasi. Hasil penelitian menunjukkan bahwa terdapat pengaruh konsentrasi M-Bio terhadap kecepatan pengomposan sampah sayur pasar, konsentrasi yang paling cepat pengomposannya adalah konsentrasi 0,1 M atau 10 ml M-Bio per 100 ml air gula.Kata kunci: konsentrasi, kecepatan, kompos, M-Bio, sampah
