DIAN ARYANI: Pengaruh Kosentrasi Dekstrin dan Perbandingan Sari Mengkudu dan Sirsak terhadap Mutu Tablet Effervescent, dibimbing oleh SETYOHADI dan LASMA NORA LIMBONG.
Penelitian ini dilakukan untuk mengetahui adanyan pengaruh kosentrasi dekstrin dan perbandingan sari mengkudu dan sirsak terhadap mutu tablet effervescent. Penelitian ini dilakuka pada Januari-Februari 2012 di Laboratorium Teknologi Pangan, Fakultas Pertanian USU, Medan, menggunakan rancangan acak lengkap faktorial 2 faktor yaitu kosentrasi dekstrin (K) : (4, 8, 12, 16%) dan perbandingan sari mengkudu dan sirsak (90:10%, 80:20%, 70:30%, 60:40%). Parameter yang dianalisa adalah : kadar air, daya larut, kecepatan larut, kadar vitamin C, total asam, pH dan uji organoleptik warna, aroma dan rasa.
Hasil penelitian menunjukkan bahwa kosentrasi dekstrin memberikan pengaruh berbeda sangat nyata terhadap kadar air, daya larut, kecepatan larut, kadar vitamin C, total asam, pH dan uji organoleptik warna, aroma dan rasa. Perbandingan sari mengkudu dan sirsak memberikan pengaruh berbeda sangat nyata terhadap kadar air, daya larut, kecepatan larut, kadar vitamin C, total asam, pH, dan uji organoleptik warna, aroma dan rasa. Interaksi kedua faktor memberikan memberikan pengaruh berbeda sangat nyata terhadap daya larut dan uji organoleptik rasa tetapi berbeda tidak nyata terhadap kadar air, kecepatan larut, kadar vitamin C, total asam, pH dan uji organoleptik warna dan aroma. Kosentrasi dekstrin 16% dan perbandingan sari mengkudu dan sirsak 60:40 menghasilkan tablet effervescent yang terbaik dan lebih diterima.

ABSTRACT
DIAN ARYANI: Effect of dextrin concentrate and Composition of Noni and Soursop Juice on the Quality of Effervescent, supervised by SETYOHADI and LASMA NORA LIMBONG.
The aims of this research was to find the effect of dextrin concentrate and composition of noni and soursop juice on the quality of effervescent tablet. This research was conducted in January-February 2012 at the Laboratory of Food Technology, Faculty of Agriculture, North Sumatera University, Medan, using completely randomized design with two factors, i.e.: dextrin concentrate (K) : (4,8,12,16%) and composition noni abd soursop juice (M) : (90:10, 80:20, 70:30 and 60:40%). Parameters analyzed were moisture content, solubility, solubility time, vitamin C content, total acid, Ph, and organoleptic values of colour, flavor, and taste.
The results showed that dextrin concentration had highly significant effect on moisture content, solubility, solubility time, vitamin C content, total acid, pH and organoleptic values of colour, flavour and taste. The composition of noni and soursop juice had highly significant effect of moisture content, solubility, solubility time, vitamin C content, total acid, Ph and organoleptic values of colour, flavour and taste. Interaction of the two factors had highly significant effect solubility and organoleptic values of taste but had no significant effect on moisture content, solubility time, vitamin C content, total acid, pH and oragnoleptic values of colour and flavour. Dextrin concentratinon of 16% and composition of noni and soursop juice of 60:40% produced the best quality of effervescent tablet.
