Abstract


Pada penelitian ini telah dipelajari sintesis mikrokapsul minyak jeruk nipis (Citrus aurantifolia) dan immobilisasinya pada sampel kain kapas. Sintesis mikrokapsul dilakukan dengan metode polimerisasi in-situ menggunakan bahan kulit (shell) melamin formaldehid. Immobilisasi mikrokapsul pada kain kapas dilakukan dengan metode pad-dry dengan menggunakan binderpoliakrilat dan crosslinking agent N-methylol dihydroxyethylene urea. Sebagai bahan pembanding,metode immobilisasi yang sama dilakukan pula pada mikrokapsul minyak jeruk nipis berbasis kulit etil selulosa. Hasil penelitian menunjukkan bahwa mikrokapsul hasil sintesis terkarakterisasi mempunyai bentuk sperik dengan ukuran partikel 0,44 – 2,10 μm. Immobilisasi mikrokapsul berbasis melamin formaldehid memperlihatkan hasil optimum menggunakan binder poliakrilat, sedangkan mikrokapsul berbasis etilselulosa memperlihatkan hasil optimummenggunakan crosslinking agent N-methylol dihydroxyethylene urea.Kedua sampel kain dengan teknik immobilisasi optimummemperlihatkan ketahanan terhadap pencucian cukup baik hingga setara 5 kali pencucian rumah tangga.
