Judul: Retensi β-karoten pada Minyak Goreng Curah yang Telah Difortifikasi Karoten dari Red Palm Oil (RPO)
Abstrak: The aim of this study was to examine the retention of β-carotene in non-branded palm oil fortified with caroten from RPO. This study began with analyzed the nutrient content, physical properties and chemical quality of RPO, followed by fortified the non-branded palm oil with caroten from RPO that equivalent with 45 IU of vitamin A and followed by analysis of the physical properties, chemical quality, and fatty acid profile. Once that it was done, repeated of tofu frying with non-branded palm oil fortified with RPO and calculation of the β-carotene content in the fried tofu as well as its contribution to the needs of vitamin A were done. The results of this research showed that the RPO contents of β-carotene was 356 mcg/gram. Fatty acids in the RPO was dominated by fatty acids palmitic (16:0) and oleic fatty acid (18:1). The viscosity of RPO was 56.5 cP. The color of RPO was red with the degree of Hue 27.74. Peroxide number in RPO was 2.54 μeq/kg with a value of 0.12% palmitic acid. Recovery from RPO fortification was 107.06%. Retention of β-caroten in the first frying phase of non-branded palm oil was 70,57%, the second was 41.83% and 14.05% for the third. The results of analysis of variance showed that repeated frying made a significant difference (p <0.05) on the retention of β-carotene. Duncan’s test results indicate that retention in oil was different from the first, second and third frying phase. The content of β-carotene of fortified non-branded palm oil per 100 grams on fried tofu products decreased from the first fried 57,26 (μg/100 g) to 10,71 (μg/100 g) in a repeat of the third fried. Duncan’s test results indicated that retention β-carotene in fortified non branded palm oil oil was different in the first, second and third frying phase.

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.
