Judul: Optimasi polivinilalkohol pada pembuatan mikrosfer polipaduan (poliasamlaktat dengan polikprolakton)
Abstrak: Mikrosfer dapat digunakan sebagai sistem pengungkung obat. Pembuatan mikrosfer dilakukan dengan metode emulsifikasi. Bahan dasar mikrosfer (poliasamlaktat (PLA) dan polikaprolakton(PCL)) dilarutkan dalam pelarut atsiri (diklorometana) kemudian diemulsikan dan didispersikan dalam pelarut lain (air) yang tidak saling campur sehingga terbentuk partikel mikro yang disebut dengan mikrosfer.
