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: Kajian Penggunaan Pompa Irigasi untuk Pertanian di Desa Babakan Raden, Kecamatan Cariu, Kabupaten Bogor.
Abstrak: One of the main problems that occur in irrigation supply is the increasing water scarcity at certain times. Actually the water is still available in the basin, it's just necessary some efforts to supply the irrigation needs. Actually the water can be raised by using water pump. If agriculture only depends on surface water and rainfall, it will not be able to increase the productivity of land because the crop water requirement is not fulfilled in some periods. The purpose of this study are determining the irrigation water pricing and finding out profitable irrigated farming. Irrigation water requirement is calculated with CROPWAT 8.0 software by using climate and rainfall conditions as input parameters, and engineering economy is used to calculate irrigation water pricing. The result shows that existence of the pump for lifting up the water to agricultural land could help farmers in increasing cropping intensity and farmers income because the farmers could plant three times a year with cropping pattern rice-rice-secondary crops or rice-rice-vegetables. The most profitable cropping pattern is rice-rice-vegetable because vegetables income is the highest among secondary crops. For sustainable farming, irrigation water cost have to based on irrigation water pricing.

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.
