Abstrak: Irrigation techniques provides water with the right conditions, the right space, and timely in a way that is effective, economical, and efficient. Planning and design of irrigation system refers to the contour of the land and the flow pattern of the system is needed. So it will impact in increase of productivity and quality of the harvest quality. Placement of irrigation channel adjoining the location of the farm, intended to have a higher elevation with farmland. The planning of secondary irrigation channels along the branches 4196.47 m with tertiary channels have an average 400-800 m length. With an area of 343.89 ha of agricultural land in total consisting of zone 1, 2, and three. Irrigation water requirements by using an open channel with trapezoidal cross-section and use the design method of Strickler required discharge of 0.6043 m3 / s with a coefficient of crop water 1,46 l / s / ha. The results of channel design successfully done according to the appendix 3, in cross section two secondary channels are used to accommodate the irrigation discharge of 0.6043 m3 / s, k = 35, m = 1, n = 2, b = 1,142 m, y = 0,571 m, v = 0,6 m / s, and I = 0,0012. Based on the results of modeling using HEC-RAS software 4.1 on irrigation channels can be said to be safe, and able to accommodate discharge of irrigation according to the needs of 0.6043 m3 / sec with input value n (manning roughness) of 0.025 and a efficiency of secondary channel 90% and 95% of tertiary channels.

Abstrak: Indonesian Center for Rice Research (ICRR) is a research institute that need precision and high accuracy to strengthen the analysis of research at the institute. One of those research is water balance analysis that need infrastructure such as irrigation. The objective of this research was to design burried pressure pipeline network system for paddy irrigation which starts from the determination of the diameter to the structural analysis. Diameter determination is done by combining the Bernoulli and Darcy-Colebrook-White equation, whereas the structure analysis following the standard of American Water Works Association (AWWA) M41 for pipes made of ductile iron. The results of design indicated that the water from the inlet could not flow by gravity, thus requiring the pump with head difference between the inlet to the outlet was 2.73 m. The main pipe diameters were respectively 36, 30, 24, and 18 in the pipeline while the branch was uniformed with 8 in. Hydraulic gradient along the flow was positive and exceeded the minimum operating pressure at each node, making sure the water can flow throughout both the main and branch pipes. Results of the analysis of the structure of the pipeline due to external loading indicated that the total pressure was still below the maximum bending stress. Total pressure also remained under maximum pressure deflection. Therefore, the pipe can withstand a design load and secure from buckling factor and ring deflection.

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.
