Abstract
Biosurfaktan palmitin etanolamida diperoleh dari reaksi antara asam palmitat dan etanolamina dengan menggunakan katalis enzim lipase imobil getah pepaya dan pelarut organik n-heksan. Pengaruh enzim lipase dapat dianalisa dengan menggunakan katalis enzim lipase ekstrak getah pepaya yang telah diimobilisasi dan reaksi tanpa katalis sebagai pembanding. Telah dilakukan tiga variasi untuk mendapatkan kondisi optimum reaksi masing-masing adalah variasi waktu, konsentrasi enzim imobil dan rasio asam palmitat terhadap etanol amida. Dari ketiga variasi tersebut maka waktu 72 jam, 12,5% enzim imobil dan rasio 1 : 7 memberikan hasil yang optimal dan hasil dilihat dari besarnya bilangan ester yang diperoleh
