Judul: Identifikasi dan Analisis Tata Guna Lahan dan Kecukupan Air Irigasi di Dua Desa Lingkar Kampus IPB (Desa Cibanteng dan Desa Benteng)
Abstrak: Water is one of the important factors in agriculture cultivation process. Irrigation planning was very important to guarantee water availability especially for paddy field. Water deficiency influenced paddy development and could reduced its productivity. To fulfill plant water requirement, irrigation must be given in right time and quality. The objectives of this research are to identify and analyse land use, irrigation requirements, and irrigation sufficiency in two villages. The result showed that land use in Cibanteng village and Benteng villages were used for settlement, farming and plantation area. Analysing by Map Info software, showed that settlement and farming area in both villages are increased, but the plantation area is decreased. The irrigation water requirement was calculated by Cropwat software and the result for Cibanteng village in second plant time is 1.47 lt/s and for Benteng village is 0.416 lt/s. The irrigation water sufficiency in Cibanteng village is 26.64 lt/s and in Benteng village is 30.42 lt/s. From that irrigation water sufficiency, the farming area in both villages can planted with paddy twice in a year and once planted with dry crop.

Judul: Analisis Tata Guna Lahan dan Kecukupan Irigasi di Desa Cihideung Udik dan Desa Cihideung Ilir, Lingkar Kampus IPB
Abstrak: Land and water are the most important elements that support agriculture. Land use is the way of planning land usage of certain area, by dividing it based on specific functions of settlement, paddy field, plantation, industry, etc. The purposes of this research are to identify land use and irrigation availability for planting, and to find out irrigation sufficiency in two villages around campus. Irrigation requirement for the both villages were sufficient. Although the agriculture area is wide, it was only used for planting of palawija. Based on the result of the both villages availability, the land can be planted with the pattern of paddy-paddy-palawija. Irrigation requirements were obtained using Cropwat. In Cihideung Udik Village, the irrigation requirement was 0.07751 l/s and the average daily debit was 22.36 l/s. In Cihideung Ilir Village, the values obtained were respectively 0.29313 l/s and 23.39 l/s. These values showed that both villages have sufficient water supply. The average daily debit were far bigger than the irrigation requirement. A change in land use was also discovered, from farming area to settlement. Total farming area in 2009 (village profile) was less than the one in 2008 (Bakosurtanal).

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.
