Abstract

Milk is an important food for baby that contains lactose. Normally, a baby could produce lactase enzyme that digest lactose, but in the diarrhea case lactose could not be digested. So, Low Lactose Milk is needed. Low Lactose Milk usually produced from rice or almonds that have low protein. Soybean (Glycine max) is the commodity with rich of protein and also contains raffinose and stachyose, which can lead flatulence. Raffinose and stachyose could be reduced by Rhizopus oryzae at tempe process from lamtoro beans.  So the aim in this research is to know the optimum time of soybean fermentation with R. oryzae to reduce stachyiose  and raffinose. The research was done with innoculation of R. oryzae isolate in the soybeans fermentation for 72 hours. N index, raffinose and stachyose level was tested. The result shows that optimum fermentation time is 48 hour and using 5% skim milk as filler.

Abstract

High diversity of rambutan varieties is potensial to develop new improved rambutan varieties. Due to limitation of rambutan genetic diversity information, the usage of RAPD (Random Amplified Polymorphic DNA) markers becomes an efficient option. This research aimed to study the diversity of rambutan from the collection of LIPI germplasm garden genotypically. Nine rambutan varieties were analyzed using six RAPD markers which generated 45 bands. Polymorphism analysis showed variation between varieties 56,6% and PIC (Polymorphic Information Content) value 0,2-0,5. UPGMA (Unweighted Pair Group Method Arithmetic) dendogram divided nine rambutan varieties in two groups with similarity index of 85-95%. First group was Si Nyonya varieties and the second group consist of Rapiah, Aceh Lebak, Unidentified, Binjai, Parakan, Si Macan, Aceh Pagar and Lebak Bulus varieties. The group differences allegedly related to the stickiness of the flesh to the seed. Aceh Lebak varieties has the closest genetic relationship to unidentified varieties of 95%.Keywords: genetic diversity, molecular marker, phylogenetic tree, PIC value, rambutanABSTRAKTingginya keragaman varietas rambutan menjadi salah satu potensi untuk mengembangkan varietas unggul baru.
