Judul: Kualitas Fisik dan Kimiawi Silase Tanaman Sorgum Manis (Sorghum bicolor L. Moench) Umur 70 Hari dengan Penambahan Aditif
Abstrak: This research was aimed to determine physical and chemical quality of sweet sorghum plant (Sorghum bicolor L. Moench) silage at 70 d harvesting time with additive inclusion of 3% rice bran (w/w) and 3% fermented sorghum extract (v/w). Experimental design used completely randomized design with three treatments and 6 replicates. Treatments consisted of P0 (control), P1 (sweet sorghum plant silage with 3% rice bran), and P2 (sweet sorghum plant with 3% fermented sorghum extract). Measured parameters were quality of plant, physical and fermentation characteristics of silage. Results showed that physical characteristics of silage at 70 d harvesting time of plant was similar at different treatment. However, fermentation characteristics were better at with or without 3% fermented sorghum extract compared to 3% rice bran inclusion treatment

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.

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.
