Abstrak: Pada tahun 2009, konsumsi beras Indonesia mencapai 139 kg per orang per tahun melebihi rata-rata dunia (60 kg per orang per tahun). Dengan laju pertumbuhan penduduk rata-rata 1,4% per tahun, kebutuhan beras Indonesia pada tahun 2030 mencapai 44 juta ton. Kebutuhan yang demikian besar tanpa diimbangi oleh produksi dikhawatirkan akan menyebabkan kerawanan pangan. Tuntutan produksi yang besar tidak terlepas dari berbagai permasalahan yang menyebabkan produktivitas padi menurun. Permasalahan tersebut antara lain penyempitan areal lahan sawah, sumber air berkurang, dan perubahan iklim ekstrim akibat pemanasan global. Fenomena perubahan iklim ekstrim antara lain kemarau panjang yang menyebabkan cekaman kekeringan., Drought is the main factor affecting rice productivity in sub-optimal dryland. Therefore, a drought tolerance upland rice cultivar is needed for extensification purposes. Two approaches to generate drought tolerance rice plants have been carried out in this research. First a genetic transformation and the second is selection for drought tolerance on rice population harboring genetic marker qtl 12.1 in the field.

Judul: Over-expression of OsDREB1A gene for improvement of drought tolerance on rice.
Abstrak: Drought is a major factor that influence the growth and productivity of rice. Drought tolerant rice varieties are needed to increase rice production. Development of improved rice varieties can be done through classical breeding and genetic transformation. The research objective was to obtain rice plants containing the construct 35S::OsDREB1A. Agrobacterium tumefaciens mediated transformation of rice cv. Nipponbare using OsDREB1A gene under the control of CAMV 35 promoter produced 81 putative transgenic rice plants (T0) positively containing the transgene based on PCR analysis. The plant height, panicle number, panicle length, and the grain number of transgenic plants were in general lower than the Nipponbare wild type. T1 seeds from selected genotypes were screened for hygromycine resistence, and rice seedlings were evaluated for tolerance to drought stress in the glasshouse, based on the standard evaluation system for rice (IRRI 1996). Five independent transgenic rice plants were identified to be tolerant to drought stress. Molecular characterization using Southern hybridization showed that these plants had 2- 4 copies of transgene. Physiological analysis showed that the drought avoidance is the possible mechanism of adaptation to drought of the transgenic plants. The drought tolerant transgenic plants were crossed to Indonesian elite rice cultivars (Ciherang, Batutegi, Code, and Konawe). Glasshouse evaluation showed that F1 transgenic plants derived from cultivars Batutegi, Code, and Konawe were more tolerant to drought than their wild-type counterparts. F1 transgenic plants were backcrossed into corresponding elit rice cultivars, and PCR analysis showed that those plants contained the transgene. These results showed that 35S::OsDREB1A could be transferred and inherited to elite rice genotipes through crossing. The new drought tolerant germplasms generated in this research can be useful materials for breeding program for improvement of drought tolerance on rice in Indonesia.

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.
