Judul: Formulasi dan Analisis Nilai Gizi Produk Mi Berbasis Sorgum (Sorghum Bicolor (L.) Moench.)
Abstrak: Sorghum as cerealia has many advantages over rice, including phenolic compound that have health potential in human body. This grain has good adaptation to dry and tropical climate that is suitable to grow in Indonesia. The objective of this research was to determine the best formula based on organoleptic (colour, taste, and texture), mineral, dietary fiber, and antioxidant activity analysis results. The initial stage of this research was to find the best formula from extrusion processing. The second stage is organoleptic test by hedonic rating and ranking. Mineral analysis (Ca, Fe, and Zn) by AAS method, dietary fiber analysis, and antioxidant by DPPH method were the last stage of this research. The variables that differentiate between formulas are ratio of sorghum to water (60%, 70% and 80%), temperature of starch gelatinitation (80oC, 90oC, and 100oC), and also frying time (1 minute and 2 minutes). Formulas with 60% ratio of sorghum (milled and unmilled sorghum) have the best quality from extrusion processing. Formula with 60% ratio unmilled sorghum at 1 minute frying has the highest rank from organoleptic test. At 2 minutes frying, formula with 60% ratio milled sorghum has the highest rank. Unmilled sorgum noodle have high dietary fiber, 33% compliance rate of nutrient adequacy, and high amount of Fe and Zn. Milled sorgum noodle also have 28% compliance rate nutrient adequacy of dietary fiber. Antioxidant activity from unmilled sorgum noodle (1.98 ppm AEAC/g product) higher than milled sorgum noodle (1.18 ppm AEAC/g product).

Abstrak: In Indonesia, rice consumption is increasing. National rice consumption reach 139 Kg per kapita per year and it is the biggest in the world. In order to have national food security, it is important to create food diversification for providing staple food alternative so as to reduce rice consumption. Sorghum is a kind of cerealia that can be a staple food alternative. This research aim to choose the right method of intstant sorghumpreparationwith good porosity and quick rehidration time. The research was divided in two steps. The first step was the soaking treatment of sorghum grain with 0.2% Na2HPO4, 1% Na-citrate and 0.2% Na2HPO4 + 1% Na-citrate(1:1). In this step, the good instant sorghum and preferred by consumer was instant sorghum that soaked with 0.2% Na2HPO4.The specification of this productwas quick rehydration time within 7.21 minute, rehydration ratio of 2.33 g/g, bulk porocity of54.81% and level of likeness 4.55 (like). The secound step was to conduct treatment of soaking at 25 oC, 35 oC, 45 oC, 50 oC and 60 oC with 0.2% Na2HPO4.Based on such criteria, the best instant sorghum was produced on the soaking in 60 oC. However, the anova statictic showed that no difference occurs amongst the soaking temperature of 45 oC, 50 oC and 60 oC. Therefore, the sampel with 45 oC of soaking temperature is chosen. The moisture content of the samples showed no signifance difference in the range of 6.21% - 7.67%. The protein content ranged between 7.95%-8.00%. The sample soaked in 0.2% Na2HPO4 soaking at 45 oC has the highets consument’s organoleptic acceptability.

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.
