Judul: Pengembangan Minuman Emulsi Minyak Bekatul Berflavor Kaya Antioksidan untuk Pencegahan Penyakit Tidak Menular
Abstrak: The purpose of this study is to improve the organoleptic acceptability rice brand oil (RBO) emulsion beverage as an alternative to high-antioxidant functional beverage. The design of this study used a completely randomized design (CRD) with a concentration factor of the flavor as much as three levels: 0,1%, 0,3%, and 0,5%. Organoleptic data were statistically analized using the Kruskal-Wallis test and Dunn test, while the other data were analized descriptively. Composition of RBO emulsion beverage comprising RBO, water, sugar esters, CMC, sucralose, salt, and flavor. The results showed that RBO emulsion beverage can be expended with the addition of 0,1% vanilla flavor, 0,5% chocolate flavor, 0,5% strawberry flavor, 0,5% soursop flavor, and 0,3% green tea flavor. The selected RBO emulsion beverage is the most preferred by 0,5% strawberry flavor. Based on TBA numbers and microbial content, the selected RBO emulsion beverage are safe to drink after 8 days stored in the refrigerator

Judul: Pangan tinggi aktivitas antioksidan berbasis minyak bekatul padi berupa minuman emulsi cokelat dan keju rendah lemak untuk pencegahan penyakit degeneratif
Abstrak: Minyak dedak padi (RBO) mempunyai kandungan antioksidan yang tinggi, namun pemanfaatannya masih sangat sedikit terbatas. Penelitian ini bertujuan untuk menilai potensi antioksidan kedua produk tersebut yaitu minuman emulsi minyak dedak coklat dan keju rendah lemak. Pembelajaran ini dibagi menjadi dua tahap. Tahap pertama adalah perumusan minuman emulsi. Tahap kedua adalah pembuatan keju rendah lemak dengan nasi substitusi minyak dedak. Formula minuman emulsi yang dipilih, berdasarkan hasil Uji hedonik keempat formula minuman emulsi adalah formula 1:3 (RBO-cokelat konsentrat : air) dengan komposisi minyak dedak padi dan coklat 6,29% dan 1,26% masing-masing. Minuman emulsi yang dipilih memiliki antioksidan kapasitas 37,68% dengan nilai AEAC 30,75 mg Vit C/100 g. Hasil dari Angka TBA, kandungan protein, lemak, karbohidrat, abu dan air sebesar 0,12 mg malonaldehida eq/kg, masing-masing 0,24%, 0,52%, 6,74%, 0,15% dan 92,32%. Peningkatan konsentrasi coklat dan RBO mempengaruhi hasil secara signifikan parameter kimia (p<0,05). Sedangkan keju rendah lemak dengan substitusi RBO mempunyai kapasitas antioksidan sebesar 92,26% dengan nilai AEAC sebesar 785,37 mg Vit C/100 g. Angka TBA, kandungan protein, lemak, karbohidrat, abu dan air masing-masing 0,06 mg malonaldehid eq/kg, 23,60%, masing-masing 18,02%, 21,51%, 5,90% dan 36,38%. Dibandingkan dengan komersial keju rendah lemak, keju rendah lemak RBO memiliki kapasitas antioksidan dan air lebih tinggi kandungan sedangkan angka TBA, kadar protein, lemak, karbohidrat dan abu lebih rendah dari keju komersial. Secara keseluruhan, minuman emulsi coklat dan Keju rendah lemak berbahan dasar RBO mempunyai aktivitas antioksidan tinggi yang berpotensi mencegah penyakit tidak menular.

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.
