Judul: Glycemic Index Values of Instant Porridge Prepared from Cassava Starch and Cassava Resistant Starch
Abstrak: Resistant starch is a starch that indigestible by enzymes. Resistant starch has health benefits effect, one of which has a slow effect in increasing level of glucose in the blood. Several researchs have shown association between resistant starch content in foods with glycemic index. The objective of this study is to observe the glycemic index value of foods prepared from cassava starch and cassava resistant starch. Cassava resistant starch was made using one and three autoclaving-cooling cycles. Four instan porridges were used in this study namely cassava starch porridge, cassava modification starch prepared using one autoclaving-cooling cycle (one cycle) porridge, cassava modification starch prepared using three autoclaving-cooling cycle (three cycle) porridge, and cassava modification starch porridge with added protein and fat from soy protein isolate, vegetable oil, and eggwhite. The results of analyses showed that resistant starch content of cassava starch porridge, one cycle cassava modification starch porridge, three cycle cassava modification starch porridge, and cassava modification starch porridge with added protein and fat were 4.46% db, 7.09% db, 8.00% db and 5.09% db respectively while the in vitro starch digestibility of those porridges were 83.76% db, 77.94% db, 76.63% db, and 79.32% db respectively. Glycemic index value of cassava starch porridge, one cycle cassava modification starch porridge, three cycle cassava modification starch porridge, and cassava modification starch porridge with added protein and fat were 97.74, 93.69, 106.09, and 93.96 respectively. All porridges can be classified as high index glycemic index food product. Statistical test showed that resistant starch manufacturing process does not affect the glycemic index value (p>0.05).

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.
