Judul: Analisis Efektivitas Waduk Ciawi Menggunakan Model SWAT Sebagai Upaya Pengendalian Banjir DAS Ciliwung
Abstrak: Management of the upstream watershed was significant factor because it had a role as the water catchment area to decrease the surface flow and potential flood. Ciliwung watershed had been gaining attention because the Indonesia central government, which is Jakarta, was located in the downstream of that watershed frequently flooded. The Ciawi Reservoir construction program on the upstream watershed was expected could help to recover that issue. The aim of this research was to analyse the effectiveness of Ciawi Reservoir by hydrology response that obtained by apply the SWAT model. The scenario of reservoir modelling was made on the hydrology simulation that had been formed, so the alteration of hydrology response that happened before and after the reservoir model applied could be known. There were 28 subbasins and 516 HRUs with 9 types of landuse, 3 soil types, and 5 slope classes on Sub Ciliwung Hulu watershed. The reservoir modelling with 15 scenarios indicated the alteration of flow discharge that specifically observed on outlet point 1 (Katulampa). The highest total discharge derivation was 158.626 m3 s-1 (34%), while the highest peak discharge derivation was 27.07 m3 s-1 (47.79%), and the best KRS value was 28.326 with good category. Based on the obtained result, the scenario of reservoir modelling managed to minimize the flow rate, so it could be said that the construction of Ciawi Reservoir was considered effective enough.

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.

Judul: Sifat fisik dan kandungan Fe Meatloaf yang menggunakan tepung daging sapi sebagai bahan baku
Abstrak: Meatlof merupakan produk yang serupa dengan sosis. Hal yang membedakannya ialah pada meatloaf dilakukan pengisian ke dalam loyang dan dipanggang pada suhu 180 °C selama 30 menit. Meatloaf biasanya terbuat dari daging segar, yang memiliki nilai gizi yang tinggi, baik dari segi nilai biologis, kecernaannya maupun kelengkapan asam aminonya dibandingkan bahan nabati, namun masih dinilai sebagai bahan pangan yang sifatnya perishable (mudah rusak). Pembuatan tepung daging melalui proses freeze drying bertujuan untuk meningkatkan umur simpan dan memudahkan pemanfaatannya dalam pembuatan produk olahan. Penggunaan tepung daging sapi dalam pembuatan meat loaf daging sapi diharapkan menjadi alternatif dalam pemenuhan kebutuhan protein hewani dan menjadi langkah awal untuk inovasi teknologi pembuatan meatloaf daging sapi yang praktis.
