Abstract

The potential of hilly dry land needs to be developed for limited land farming to have an equal distribution of food security in various potential areas. Many existing drylands, especially in hilly and sloping areas, have not been managed optimally for agriculture due to limited support for practical irrigation techniques. Utilizing differences in existing land elevation is a potential that can be exploited by irrigation techniques that require water pressure. The perforated pipe system irrigation technique has similarities to the mini sprinkler system because it uses water pressure, and it is very possible to be applied to sloped land conditions, but the ability of the perforation system needs to be known further so that it can be used for practical irrigation. For this reason, it is necessary to test the perforated irrigation system with certain variations of the slope of the beam range and uniformity, so that later it can be used as an initial reference. The test model uses a water source from a tendon as high as 3.7 m and with a tank capacity of ± 200 liters. The diameter of the transmission pipe is ½ inch with a length of 2.55 meters, and the lateral pipe as a perforation pipe with a 3mm hole consists of 3 pipes with a pipe length of 4 meters with a diameter of 1/2 inch and the distance between the holes of the perforation pipe is 60 cm. The test was carried out on 4 variations of the slope of 10º, 20º, 30º, and 40º with 4 variations of head 1 = 2.855 m, head 2 = 2.35 m, head 3 = 1.85 m, and head 4 = 1.30 m. Based on the research results, it shows that the greater the slope of the transmission pipe, the higher the head will be. The uniformity of the perforation irrigation was getting smaller the larger the slope with a minimum value of 85% and the highest being 91%. A large perforation beam is obtained at transmission slopes of 20º and 30º, namely 2.66 m and 2.40 m.

Abstract

Estimated flood discharge value for water structure design, ideally determined based on the frequency analysis of measured discharge data. However, the measured discharge data is often not recorded or if the length is limited. So, it needs the technique in getting the design flood value from rain data through the Synthetic Unit Hydrograph (SUH) method. This study examined the suitability of the three (3) SUH methods (Nakayasu, Limantara and ITB2) in generating the design flood discharge and compared it with the Observed Unit Hydrograph (OUH) of the elongated shape watersheds, namely Sidutan and Reak. The main values that are compared are peak discharge, peak time, and base time of HSS to the HSO value. The results obtained from the Sidutan watershed and the Reak watershed are both elongated shape watershed, have almost the same length as the main river, but the area of the Sidutan watershed is greater than Reak watershed. The average OUH of both watersheds indicated that both Qp and Tb of the Sidutan watershed are greater than Reak, but the time peak hydrograph (Tp) was reached at almost the same time. The SUH method that produced unit hydrographs closest to OUH is Nakayasu, then ITB2 and Limantara, respectively.

Abstract

Complete rainfall data for an extended period is needed to facilitate hydrological analysis. However, there are many obstacles to obtaining the measurement rainfall data as a limitation of rain gauges, especially in remote areas. This study aims to determine the accuracy of rainfall data estimated by the IMERG (Integrated Multi-satellitE Retrievals for GPM) satellite and obtain a correction factor to improve its compatibility with measured rainfall data. The IMERG satellite rain data was corrected using the regression method and the average ratio. The accuracy of the IMERG satellite rain data against the measured rain data is measured from the NSE, R, RMSE, and RB values. The analysis results show that the accuracy of the GPM satellite daily rain data is very low but improving for the ten-daily and monthly periods. Generally, the best correction factors for daily, ten-daily, and monthly periods are obtained using simple linear regression methods and 2nd-order polynomials. The corrected IMERG satellite rain data increase in accuracy, where the monthly rainfall data performs well, the ten-daily data generally complies, and the daily data has not shown good performance. The average values of NSE, R, RMSE, and RB for daily data are 0.14 (poor), 0.37 (weak), 9.18 mm, and -0.12%, respectively; for ten-daily data respectively, 0.40 (fair), 0.63 (strong), 39.42 mm, and 1.47%; and for monthly data are 0.55 (fair), 0.74 (strong), 80.19 mm, and -0.07%. The ten-daily and monthly rainfall data from the IMERG satellite can be used as a rain source data alternative in the Bima and Dompu areas by applying a correction factor.
