- Abstract
The irrigation water discharge at the intake gate must be in line with the area of agricultural land. The dimensions of primary, secondary and tertiary irrigation canals must be in accordance with the area of agricultural land and the cropping pattern applied. The aims of this study are (1) to analyze the need for irrigation water at the intake of the Sidopangus Irrigation Area (DI) Semarang Regency; and (2) analyzing the dimensions of secondary irrigation channels in DI Sidopangus, Semarang Regency. This research was conducted at the Sidopangus DI whose source of water comes from the Sidomble Dam in Semarang Regency. Survey method was used in this research. Analysis of irrigation water needs and channel dimensions was done manually using the referral KP-01. The results of the study that can be stated was that the need for irrigation water in rice fields (NFR) was equal to 0.813 l/s/ha and the smallest maximum irrigation water demand (DR) was equal to 1.251 l/s/ha which occurs in late November to early December. The study also found that the dimensions in the secondary channel ie channel width (b) were 1.42 m; water level at the bed of the channel (h) is 0.71 m; slope of the irrigation channel (m) is 1; and irrigation canal height is 0.50 m.
