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: Pengaruh Intervensi Minuman Emulsi Ready to Drink Minyak Bekatul – Cokelat Terhadap Profil Lipid Mahasiswa Obes
Abstrak: Minyak bekatul telah dikenal memiliki efek hipokolesterolemik oleh karena kandungan -oryzanol di dalamnya dan dikembangkan menjadi minuman fungsional. Tujuan penelitian ini adalah untuk mempelajari kebiasaan subyek mengonsumsi makanan sumber lemak, menganalisis kandungan asam lemak minuman ready to drink minyak bekatul-cokelat, serta efeknya terhadap profil lipid plasma pada mahasiswa obes. Desain penelitian yang digunakan adalah pre-eksperimental studi dengan one group pretest-posttest design menggunakan enam mahasiswa dan enam mahasiswi IPB. Setiap subyek diberikan dua gelas setiap harinya atau setara dengan 57.6 mg γ-oryzanol. Tidak terdapat perbedaan signifikan terhadap konsumsi kebiasaan makan sumber lemak subyek pada masa sebelum dan selama masa intervensi. Asam lemak dominan pada minuman emulsi ready to drink minyak bekatul-cokelat adalah asam oleat sebanyak 32.57%, asam linoleat sebanyak 28.44% dan asam palmitat sebanyak 17.51%. Kadar total kolesterol dan kolesterol LDL secara signifikan menurun sebesar 21.2 mg/dl and 18.7 mg/dl, sedangkan kadar kolesterol HDL dan trigliserida tidak mengalami perubahan signifikan. Secara umum minuman bermanfaat bagi kesehatan yaitu dengan cara menurunkan kadar kolesterol dan kolesterol-LDL plasma mahasiswa obes.

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.
