Judul: Analisis Hidrologi di Sub DAS Ciliwung Hulu Menggunakan Model SWAT
Abstrak: The Ciliwung Watershed is one of the area which has a critical condition. It caused by residential increased in upper area. This condition change of hydrologic characteristics such as run off increased and flood risk. It means Ciliwung Watershed management must be improve. SWAT model can applied for watershed management scenario, such as predict run off and water balance. Model validation used daily data from 2001 to 2010 resulted the NSE 0.53 and R2 0.57, it means SWAT model is satisfy to predict hydrological conditions of the Upper Ciliwung Watershed. SWAT model shows by input annual rainfall 3 790.12 mm results run off 38.45% (1 457.38 mm/year), evapotranspiration 22.06% (836.04 mm/year), lateral flow 20.31% (769.92 mm/year), percolation 15.28% (579.02 mm/year), and ground water 3.90% (147.77 mm/year). Applied recharging well scenario at settlement area with the infiltration function similar with forest predict can reduce run off 46.17% (672.93 mm/year).

Judul: Pengelolaan Lahan Terbaik Hasil Simulasi Model SWAT Untuk Mengurangi Aliran Permukaan di Sub DAS Ciliwung Hulu
Abstrak: Serious problems encountered in watershed management are related to the vegetated-land conversion and increasing areas of critical lands. The later is caused by inproper land management ignoring land capability and suitability, lack of application soil and water conservation techniques and landuse changes. Measurement of various field parameters at watershed scale was not easy to do because of its complex characteristics which sometime interrelated to each others. Modelling can be useful to understand processes involving those parameters in a watershed. SWAT (Soil and Water Assessment Tool) is a physically-based model developed to predict the impacts of land management practices on water, sediment and agricultural chemical yields in large complex watersheds with varying soils, land uses and management conditions over long periods of time. The objectives of this research were: (1) To analysis application of SWAT model to predict surface runoff, erosion and nutrient loss (nitrate) in upper Ciliwung Hulu watershed, (2) To predict Best Management Practices in agriculture field in order to reduce surface runoff in upper Ciliwung Hulu watershed. Methods applied includes collection of primary and secondary data, preparation and analysis of the input data, application of the SWAT model, analysis of the calibration parameters, determination of the validation values and simulation land management. The research was held in the period of June 2011 until June 2012. Based on daily flow discharge in February and March 2008 and 2009, the calibration result showed an R value of 0,80 and NSE value of 0,55. Validation result in February and March 2009 and 2011 showed an R value of 0,88 and NSE value of 0,74. These results described that SWAT model can be used to predict hydrological processes in upper Ciliwung Hulu watershed. Calibration of sediment observation and nitrat data were not successful because the values between observation and simulation were so different. This condition made erosion prediction and nutrient loss prediction could not be proceeded. Best Management Practices recommended terraces to be applied in upper Ciliwung Hulu watershed as terrace is the most effective soil conservation techniques to reduce surface runoff.

Abstrak: Keeoa Madagaskar (Gromphadorhina portentosa) adalah kecoa yang besar, tidak bersayap yang berasal dari Madagaskar, sebuah pulau yang berada di sebelah tenggara benua Afrika Keeoa ini sering disebut "kumbang Madagaskar yang berdesis" untuk menghilangkan kesan yang negatif tentang kata-kata "keeoa". Akhir-akhir ini, kecoa ini menjadi populer di luar negeri sebab sering digunakan sebagai hewan peliharaan (pets), karya ilmiab untuk anak-anak SD, obyek pameran di kebun binatang dan untuk makanan kadal dan burung hantu. Beberapa perbedaan dengan keeoa pacta umumnya, keeoa Madagaskar tidak memiliki sayap, bersih, tidak berbau, j inak, lambat dan tidak menggigit. Umumnya kecoa Madagaskar ini diberikan pakan berupa buah-buahan antara lain ape], pi sang dan buah anggur. Jenis makanan tersebut cukup mahal di Indonesia untuk diberikan pacta temak karena lebih diutamakan untuk konsumsi manusia, oleh karena itu dicari pakan lain yang murab, mudah didapat dan ketersediaannya teIjamin sehingga dapat memberi pertumbuhan yang baik dan optimum pada keeoa
