Judul: Pola Konsumsi Pangan dan Pengaruh Minuman Minyak Bekatul- Cokelat terhadap Aktivitas Superoksida Dismutase Mahasiswa Obes
Abstrak: Rice bran oil and chocolate have been known for antioxidant capabilities from their bioactive compounds. Therefore, rice bran oil and chocolate were made as functional drink. The objectives of this research were to identify eating habits and to analyze the effect of rice bran oil-chocolate drink intervention on superoxide dismutase activity in obese college students. This research used a preexperimental design with one group pretest-posttest design, consisted of 12 obese IPB college students. Intervention was performed by giving two glasses of drink every day and equivalent to 57.2 mg of γ-oryzanol. Consumption of rice bran oilchocolate drink significantly increased intake vitamin E in obese college students (p<0.05). Activity of plasma superoxide dismutase between pre- and postintervention was not significantly different (p>0.05) but tends to decrease after the intervention and probably because of γ-oryzanol high protection capabilities againts oxidative stress, so it can decrease plasma superoxide dismutase activity of obese college students.

Judul: Angka lempeng total minuman emulsi minyak bekatul-cokelat dan pengaruh intervensinya terhadap kadar malondialdehid (MDA) plasma mahasiswa obes
Abstrak: Tujuan dari penelitian ini adalah untuk mempelajari jumlah plate count minuman emulsi minyak dedak padi-cokelat dan pengaruhnya terhadap kadar malondialdehid (MDA) plasma siswa obesitas. Penelitian ini menggunakan pra-eksperimental yang dirancang dengan one group pretest – posttest. Penelitian ini melibatkan 12 subjek obesitas yang terdiri dari 6 laki-laki dan 6 perempuan. Setiap subjek diberikan 2 gelas per hari setara dengan 57,6 mg -oryzanol. Hasil penelitian menunjukkan bahwa minuman emulsi ini layak dan aman dikonsumsi, karena total mikroba dari analisis Total Plate Count (TPC) berada di bawah batas maksimal yang ditetapkan Standardisasi Nasional Indonesia. Rata-rata kadar MDA plasma subjek mengalami penurunan setelah intervensi, namun analisis uji t menunjukkan tidak signifikan (p>0,005).

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.
