Abstrak: Black rice and red rice are claimed to be safely consumed by the diabetic patients and known to have high antioxidant content. Rice which is grown in different area may have different physical and chemical properties, thus it may also affect the rice functional properties. The purposes of this study were to determine the physical properties (hardness, color and gelatinization profile), chemical properties (proximate composition, total phenolic content, total flavonoid content and digestibility of starch) and the functional properties (antioxidant activity) of the black rice and red rice from Cianjur, Solok and Tangerang and also to observe the effect of cooking on the reduction of total phenolic content, flavonoids and antioxidant activity. In vitro analysis of starch digestibility with α-amylase showed that the starch digestibility of rice which had anthocyanin pigments (black and red varieties) ranged from 56.10-83.43%, smaller than white rice which was 87.35%. In addition, the result also showed that the total phenolic content, flavonoid and antioxidant activity in black, red and white rice were decreasing after cooking process. Black rice and red rice from Solok and Cianjur had the better chemical content and functional properties than the Tangerang one.

Judul: Karakterisasi Aksesi Padi Beras Merah dan Hitam (Oryza sativa L.)
Abstrak: Red rice and black rice has more advantage than white rice, including higher nutrient content than white rice. Red and black rice has anthocyanin, a substance causing the colors on the rice pericarp. Most of the red rice and black rice that has been cultivated are landrace cultivars. The local varieties can be one source of characters for plant breeding. Characterization was done to find out the potential characters that contained in the landraces. Plant material used were local rice accessions 22 red and black rice varieties with Aek Sibundong as check. The research results showed that local red and black rice accessions gave very significant effect on the observed variables . Accessions that has the potential to be developed are Sidrap (G7), Malang (G9), Pasaman (G13), Temanggung (G21), Purworedjo (G23), Mesuji (G25), Garut (G26), Meulaboh (G27), and Nisam (G34). They achieved productivity more than 4 ton.ha-1.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
