Judul: Analisis Penyediaan Dan Distribusi Air Bersih Untuk Kampus Dramaga Institut Pertanian Bogor
Abstrak: The purpose of this study is to determine the amount of water required in each unit within the scope of IPB Dramaga campus, to find out the amount of water that can be produced IPB water treatment plant and to create water supply system. This research was conducted from June to October 2010. The result shows that WTP Cihideung-IPB is capable to produce treated water about 137.175 m3/hr, WTP Ciapus-IPB (old) can produce treated water around 44.1 m3/hr, while WTP Ciapus-IPB (new) serving residential lines is capable to produce treated water of 65.95 m3/hr. In this research note also that the amount of water used on average per day during holidays amounted is about 1806.2 m3 (993.4 m3 in Fahutan's tower and the Fapet's tower 812.8 m3) and the amount of water used per day in full activity day amounted is about 1959.77 m3 (1070.93 m3 in the Fahutan's tower and 888.83 m3 in the Fapet's tower). Also note that during holiday peak load amounted is about 137.2 m3 in the Fahutan's tower (09.00 - 10.00) and 98.8 m3 in Fapet's tower (at 7:00 a.m. to 8:00), while at full activities peak load is 132 m3 in the Fahutan's tower (at 8:00 a.m. to 9:00) and 121 m3 in the Fapet's tower (11.00 - 12.00). In the dormitory known path needs per day amounted is about 667.890 m3. From these values it can be concluded that the quantity of treated water production on campus IPB Dramaga is sufficient. However, the problems at the level of a water distribution to the consumer level often lack even absent. In terms of quality, treated water from the installation on campus IPB Dramaga have values that fall into water quality standards

Judul: Analysis of clean water required and head loss at water distrisbution in IPB Darmaga Campus Bogor
Abstrak: The objectives of this study were to find clean water needs for campus IPB Darmaga, to know the peak time water consumption in IPB Darmaga, to calculate the amount of head loss and leakage that occurred in the distribution network as well as the general condition of the water supply in IPB Darmaga. Water requirement was calculated by monitoring actual water usage on the main supply meter, in order to get the daily usage and peak time usage. Furthermore, the head loss was calculated using Darcy-Weisbach and Bernoulli equations. The prediction results showed that the academic community of IPB needs clean water 2,670.84 m3/day, while the actual use of clean water could reach 3,566.62 m3/day. This signifies the use of water in the IPB is very large when compared to standard needs. The total production capacity of clean water in IPB was 4,471.75 m3/day consisting of 903.60 m3/day from Water Treatment Plant (WTP) 1 Ciapus, 1,319 m3/day from WTP 2 Ciapus, and 2,249.15 m3/day from WTP Cihideung. Peak time of water use in IPB occurred at 09.00 until 10.00 am with the highest consumption could reach 137 m3/hour. Water leaks that occur in distribution channels Fahutan tower was 88-90 liters/hour or 64.80 m3/day. While the magnitude of head loss that occurred in the pipeline transmission from WTP Cihideung toward the Fahutan tower was 14 m and elevation difference between the two places was 41 m. Pump head that occurred was 55 m.

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.
