Judul: Analysis of Cidanau River Discharge using SWAT Application.
Abstrak: management. The water demand always increases in line with the growths of population, industry and business, but the water availability is ascertained to satisfy those needs continuously. Therefore, it is necessary to analyze water availability in a specified watershed integrated with various aspects in hydrology. The objective of this study was to determine water availability in Cidanau watershed by analysing the relationship of rainfall and river discharge using the Soil and Water Assesment Tool (SWAT). The watershed is located in Banten Province and covering 22 620 ha. Input data were Digital Elevation Models, land use, and soil map. The procedures were including collection and process of climate data, trend analysis of water availability, determination of dry periods, discharge measurements, discharge analysis and calibration using SWAT. The results showed that water demand would reach 2.854 m3/s in 2020 while the estimated of average discharge was 5.282 m3/s, and the minimum discharge was 0.5 to 1 m3/s. Dry periods occurred from May to October with the average of 171 days per year. SWAT has generated 461 HRU that described the spatial condition of the whole watershed. Calculated discharges with SWAT compared to the measured discharges having The Nash-Sutcliffe Index of 0.534, and correlation coefficient of 0.68. Since this study used limited data then further studies should be continued by collecting more data of discharges and climates.

Judul: Analisis Debit Aliran Sungai Menggunakan Model SWAT di Sub DAS Ciasem Kabupaten Subang Jawa Barat
Abstrak: Increasing developed area and decreasing forest area lead to increase runoff coefficient that further to increase the stream discharge during rainy season and draught in dry season. The hydrological model can be applied to understand that phenomena. One of them is SWAT model. Application SWAT model in this research is focused only in rainfall transformation into discharge. Research is conducted in Ciasem Sub Watershed. The aim of this research is to know the dinamics of land use change and stream discharge in Ciasem Sub Watershed, also to know the effectiveness of SWAT Model for analyzing stream discharge by using available data in Ciasem Sub Watershed. The change of land use at 2003, 2006, and 2009 particularly happened on paddy field which was changed into a mixed agricultural dryland area of about 3253,8 ha, decreased runoff coefficient. Discharge estimation using SWAT model with measured rainfall at Curugagung Rain Station as input did not fit succesfully to measured discharge at Ciasem Sub Watershed outlet. Discharge estimation using SWAT model with simulated rainfall as input results better fitting to measured discharge at Ciasem Sub Watershed outlet with the value of R² > 0,51 and NS > 0,74. The result of the simulation showed that land use change of paddy filed to mixed agricultural dryland decreased runoff coefficient from 0,21 to 0,12 and also monthly maximum runoff discharge from 117,55 m3/s to 79,68 m3/s.

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.
