<![CDATA[ABSTRACTThe aim of the research is study the effect of concentration arrowroot starch and pHsaccharification ( research I ), and the influence of glucoamylase concentration andsaccharification time ( research II ) toward of glucose syrup. This research used CompletelyRandomized Design which consists of two factors with two replications. The first factor onarrowroot starch is concentration (25; 30; 35%), the second factor is the pH ofsaccharification (4, 5, 6). While the first factor of research II of glucoamylase is enzymeconcentration (0.06; 0.075, and 0.09 ml), the second factor is time saccharification (12; 18;24 hours). The best result of glucose syrup from the first research is obtained fromcombined treatment arrowroot starch concentration of 30% and pH saccharification 6.0 with56.590% DE, 37.923% reducing sugar, 60.779% water content, viscosity of 4.6 cps, 0.341%dextrin, 0.388% maltrotriose, 3.094% maltose and 32.897% glucose, while the secondresearch is at treatment concentrations of enzyme glucoamylase0.075 ml andsaccharification time 24 hours with the criteria of 53.138% DE, reducing sugar 32.233%,64.091% water content, viscosity 4.70 cps, 0.330% dextrin, 0.352% maltrotriose, 2.565%maltose and 33.472% glucose.Key word : glucose syrup, arrowroot strach, α-amylase, glukoamylaseABSTRAKTujuan penelitian ini yaitu membuat sirup glukosa dari pengaruh konsetrasi pati garut , pHsakarifikasi ( Penelitian I ) ; pengaruh konsentrasi enzim glukoamilase dan lama sakarifikasi (Penelitian II) . Penelitian ini menggunakan Rancangan Acak Lengkap terdiri dari dua faktordengan dua kali ulangan. Faktor pertama pada penelitian I yaitu konsentrasi pati garut (25;30; 35%), faktor kedua yaitu pH sakarifikasi ( 4; 5; 6 ). Sedangkan pada penelitian II faktorpertama yaitu konsentrasi enzim glukoamilase ( 0,06; 0,075; dan 0,09 ml ) , faktor keduayaitu waktu sakarifikasi (12; 18; 24 jam ). Sirup glukosa terbaik dari penelitian I diperolehdari kombinasi perlakuan konsentrasi pati garut 30% dan pH sakarifikasi 6,0 dengan 56,590%DE, gula reduksi 37,923%, kadar air 60,779%, viskositas 4,6 cps, dekstrin 0,341% ,maltrotriosa 0,388%, maltosa 3,094% dan glukosa 32,897%, sedangkan dari penelitian IIpada perlakuan konsentrasi enzim glukoamilase 0,075 ml dengan waktu sakarifikasi 24 jamyang mempunyai kriteria 53.138 %DE, gula reduksi 32,233%, kadar air 64,091%, viscositas4.70 cps, dekstrin 0,330% , maltrotriosa 0,352%, maltosa 2,565% dan glukosa 33,472%.Kata kunci : sirup glukosa, pati garut, α-amlysae, glukoamylase]]>
