LEMBAR KERJA BERBASIS PROYEK PADA PEMBUATAN KRIM ANTIJAMUR

Abstract

Konsep koloid bersifat abstrak dengan contoh konkrit, sehingga diperlukan suatu lembar kerja praktik aplikatif yang sesuai dengan konsep tersebut. Pemanfaatan lengkuas dalam bentuk krim antijamur dengan pengaplikasian pembelajaran proyek, dapat mewujudkan pembelajaran yang bersifat bermakna dan dekat dalam kehidupan sehari-hari. Tujuan penelitian ini untuk menyusun LK berbasis proyek, mengetahui uji kelayakan LK berbasis proyek, dan penentuan karakteristik terbaik krim antijamur dari berbagai variasi komposisi fasa terdispersi, pendispersi dan keberadaan zat tambahan. Lembar kerja dibuat menggunakan metode research and development. Prosedur dalam lembar kerja ditentukan melalui pembuatan dan analisis karakteristik krim antijamur dari fraksi nonpolar ekstrak aseton lengkuas. Hasil uji validasi terhadap format LK dinyatakan valid, dengan nilai rata-rata rhitung yang diperoleh sebesar 0,84, persentase keterbacaan LK adalah 97%, sedangkan karakteristik LK yang dihasilkan membuat siswa dapat menentukan konsep dan prosedur pembuatan sistem koloid emulsi, faktor yang mempengaruhi karakteristik emulsi dan penerapan koloid.
