Judul: Pengaruh Penambahan Na2EDTA terhadap Ketersediaan Biologis Besi (Fe) pada Berbagai Olahan Terigu
Abstrak: Na2EDTA in generally added to foods to prevent oxidation, discoloration, and enhances iron bioavailability by chelating added minerals. The purpose of this study was to determine the bioavailability of iron changes that occur due to the addition of Na2EDTA in a variety of processed wheat flour. This study used a nested design with factors of processed wheat flour that nested on Na2EDTA wheat flour. The treatment was consists of Na2EDTA wheat flour in the form of 2 levels without Na2EDTA (control) and with Na2EDTA, while wheat flour processed was consists of 3 levels was wheat flour processed by frying (donuts), steaming (steamed bun), or baking (bread). Bioavailability of iron (Fe) was tested by using in vitro method that made a simulation of human digestion using pepsin and pancreatin bile. Test results of this study showed that wheat treated controls and the addition of Na2EDTA showed no significantly difference (p>0.05) in the value of bioavailability. As well as the iron bioavailability on factors of wheat flour processed that nested on Na2EDTA wheat flour (p>0.05). Since rever to the value, there was an increase in wheat flour processed by frying (donuts) way of 9.5654%.

Judul: Bioavailabilitas Besi dan Seng Produk Pangan Olahan Berbasis Terigu yang Ditambahkan Na2EDTA dengan Kombinasi Berbagai Minuman
Abstrak: Some wheat flour based food products are commonly consumed with drinks, such as tea, plain water, milk and fruit juice. Nutrients and other food components present in food consumed together with drink may interact one another and possibly affect nutrient bioavailability. This research aimed to identify in vitro bioavailability of iron and zinc on Na2EDTA-added wheat flour based foods combined with several drinks. It was expected that addition of Sodium EDTA to wheat flour would increase bioavailability of iron and zinc. Food products used were donuts, bakpao (steamed bun) and white bread. Kind of drinks used as the combination of foods were plain water, tea, guava juice and milk. The results showed that iron bioavailability were varied between 2,46–21,82%, whereas bioavailability of zinc were between 3,73–19,39%. Statistical analyses using one way ANOVA test showed that types of combinations significantly affect the iron and zinc bioavailabiliy. In this study, Na2EDTA could not maintain bioavailablity of iron and zinc from inhibitor contained in tea. Ascorbic acid contained in guava juice increased iron bioavailability. Amino acid contained in milk is potential enhancer of iron and zinc bioavailability. In conclusion, the best drink combination to maximize iron and zinc bioavailability on Na2EDTA-Added Wheat Flour Based Foods Combined with Several Drinksis milk.

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
