      Abstract
      Mikrofibril selulosa merupakan biomaterial yang dapat diaplikasikan pada berbagai bidang. Rumput laut Ulva lactuca merupakan salah satu sumber potensial untuk mikrofibrilasi selulosa. Deep Eutectic Solvent (DES) merupakan pelarut baru yang ramah lingkungan dan dapat dijadikan sebagai pelarut dalam mikrofibrilasi selulosa. Penelitian ini bertujuan menentukan konsentrasi DES untuk menghasilkan mikrofibril selulosa dan mengkarakterisasi fisiko-kimia mikrofibril selulosa dari rumput laut Ulva lactuca. Penelitian ini meliputi preparasi bahan baku, penghilangan ulvan, delignifikasi, bleaching, dan mikrofibrilasi selulosa dengan perlakuan HCl dan DES (ChCl/urea 1:2) dengan konsentrasi 10%, 20%, dan 30%. Mikrofibrilasi dengan DES dengan konsentrasi 10-30% berhasil menghasilkan mikrofibril selulosa yang berbentuk seperti jaring laba-laba. Diameter mikrofibril selulosa terkecil diperoleh perlakuan DES 10%. Mikrofibril selulosa dengan perlakuan DES termasuk ke dalam selulosa amorphous. Selulosa amorphous dapat dimanfaatkan untuk bidang biomedis dan bioenergi. DES memiliki potensi sebagai pelarut untuk mikrofibrilasi.
       
      Cellulose microfibril is biomaterials that can be applied to various fields. Green macroalgae Ulva lactuca is one of the potential sources for the cellulose microfibrillation. Deep Eutectic Solvent (DES) is a new green solvent that can be used to cellulose microfibrillation. This reseacrh aimed to determine the concentration of DES to produce cellulose microfibril and to characterize the physico-chemical properties of cellulose microfibrils from Ulva lactuca. This research method includes preparing raw materials, separation ulvan, delignification, bleaching, and cellulose microfibrillation with HCl and DES (ChCl/urea 1:2) with concentration of 10%, 20%, dan 30%. Microfibrillation using DES with a concentration of 10-30% produced cellulose microfibrils shaped like spider webs. The smallest diameter of cellulose microfibrils was obtained by 10% DES treatment. Cellulose microfibrils treated with DES are classified as amorphous cellulose. Amorphous cellulose can be used in biomedical and bioenergy fields. DES has the potential as a solvent for microfibrillation.
