Abstrak: The objective of the research is to design the hydraulics structures on rural irrigation scheme, which include: analysis of irrigation water sufficiency, design of rural irrigation scheme layout, design of pump station, design of open channel, and design of diversion box. The study was conducted in the village of Pekiringan Alit, District Kajen, Pekalongan, Central Java, with two scenarios, i.e. the first scenario with cropping pattern of sugarcane and the second scenario with cropping pattern of corn-beans-melon-tomatoes. Based on analysis, the irrigation water requirements unit of scenario 1 is 0.53 l/dt/ha while for scenario 2 is 0.42 l/dt/ha. The irrigation water requirements can be fulfilled from Sragi River with minimum flow of 537 l/sec. Layout of irrigation scheme consists of 4 irrigated blocks with a total area of 27.15 hectares. Pump station was designed with a capacity of 17.99 l/sec and total dynamic head (TDH) of 14.11 meters. The irrigation water delivery system was designed with three options, i.e. trapezoidal earth channel with a bottom width of 0.3 meters and top width of 0.9 meter, rectangular lining channel with a bottom width and top width of 0.3 meters, and piping channel with a diameter of 4 inches, 3 inches, and 2 inches. The diversion box was designed with dimensions of 0.8 meters height, 0.5 meters width, 0.6 meters length.

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.

Judul: Karakteristik Protein Mioglobin dan Parvalbumin pada Ikan Tongkol Komo (Euthynnus affinis).
Abstrak: Ikan tongkol mengandung dua jenis daging, yaitu daging merah dan daging putih. Dua jenis daging memiliki kandungan mioglobin dan parvalbumin yang berbeda. Penelitian bertujuan menentukan karakteristik protein mioglobin dan parvalbumin pada daging putih dan daging merah ikan tongkol komo (Euthynnus affinis). Kandungan mioglobin dianalisis secara kuantitatif menggunakan spektrofotometri, sedangkan parvalbumin diidentifikasi menggunakan Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). Kandungan mioglobin daging merah lebih tinggi dibanding daging putih. Daging merah bagian tengah memiliki kandungan mioglobin tertinggi. Analisis spektrofotometri mengindikasikan bahwa jenis mioglobin yang dominan adalah metmioglobin. Proses pemanasan dapat merusak protein mioglobin. Kandungan parvalbumin ditemukan pada daging putih dan hanya terdeteksi pada bagian depan. Proses pemanasan tidak dapat merusak protein parvalbumin.
