Abstract

Mataram irrigation canal is an agricultural infrastructure built around 1942 with a channel length of ± 34.5 km. Changes in land use patterns that occur in Yogyakarta will certainly have an impact on changing the demand for water discharge in the canals and the ability of the canals to drain water. The tertiary network in the Mataram irrigation canal is the most influential on land use change. where the network connects the Mataram main network with the surrounding rice fields. This study reviews how much efficiency and water loss occurs in the Mataram irrigation tertiary channel. Analysis of the efficiency of the Mataram irrigation canal was carried out by comparing the discharge inflow and outflow in the channel while the analysis of water loss in the channel is carried out by calculating the amount of evaporation and seepage that occurs in the channel. Efficiency results in 25 Mataram tertiary channels. there are 9 channels where water utilization is greater than water demand indicated loss that occurs in the channel. Loss in the channel is caused using water for other factors or water leakage occurs in the channel. This is indicated by the fact that the water supplied to the canal is greater than the required amount of water. so that the percentage of water usage in this channel is more than 100%. Different conditions were obtained from the other 16 canals. where water utilization was less than the water requirement. so there was excess water in the canals. This incident occurred because the irrigation service area had experienced a change in land use or a lot of land that did not need water. This causes the downstream water discharge to be greater than the given discharge because there is additional discharge from other sources.

Abstract

Yogyakarta International Airport (YIA) is a new airport that operates in the Special Region of Yogyakarta, located in Temon District, Kulon Progo Regency. The presence of the airport will undoubtedly bring various benefits, such as increasing economic activities in the area around the airport. However, the location has a problem, namely the risk of flooding. Flooding can affect activities around the airport, such as freight forwarding activities and access to or from the airport. Based on this problem, efforts are needed to prevent the flood that occurs does not have an impact on the activities of YIA airport and the surrounding area. In this case, the researcher used the EPA SWMM program in modeling the drainage system at the site under study. Modeling the point of occurrence of flooding will make it easier to normalize and add embankments to the channel. Modeling with EPA SWMM 5.1 requires input data such as rain distribution data, watershed characteristics, and the transverse appearance of the drainage channel. The results showed an overflow in the 15 drainage channels studied. The causes of overflow are high surface runoff and sedimentation based on channels and backwaters. Efforts to overcome by normalizing and adding embankments are sufficient to overcome flooding in several channels. Meanwhile, for channels that are still experiencing flooding, other countermeasures, such as retention ponds, are needed.

Abstract

The Padang Sugihan Wildlife Reserve is facing the threat of fires, which have a detrimental impact on the ecosystem of the Sumatran Elephant habitat. To mitigate this risk, this research aims to evaluate the hydraulic efficiency of overflow weir and flap gates as interventions for peatland restoration in the Suka Pindah Canal. 1D HEC-RAS modeling indicates that without control structures, tidal fluctuations at the estuary are ineffective in maintaining soil moisture. The scenario with a flap gate at the Suka Pindah Canal estuary can increase the volume of water by up to 115% compared to the existing condition, but this water structure requires well maintenance. In contrast, an overflow weir that is 1.5 times wider than the flap gate scenario proves to be more efficient, with a 72% better increase in water volume than the flap gate, as well as a simpler design. Further analysis shows that the upstream area of the canal, consisting of low-elevation land (natural ponds), has the potential to double the water retention capacity in the canal and land. These findings indicate that control structures are effective for rewetting efforts.
