Preparation for the modernization of Kedung Putri Irrigation System (DI Putri) required a comprehensive assessment irrigation pillars, one which was at secondary level. To facilitate and development plan, clustering carried out using k-medoids method, that used representative data (called medoid) as cluster center. Then, decision making conducted by Analytic Hierarchy Process (AHP) method. Performance 21 channels stated readiness index (IKMI). The result showed 9,52% included in good...

Abstract In the last decades before entering 21fts century, many countries of world have been facing critical issues less in food production, lack energy availability and weak water recourses management as well. Beside these another phenomenon dealing with climate change also is coming up treating peoples some respects. developing country such Indonesia environmental load term increasing population rate occur tremendously. More mean more resources to be provided. However, recourse scares...

High conversion of agricultural land in Kulon Progo Regency, as such the construction Yogyakarta International Airport (YIA) and Bedah Menoreh road, has resulted food production impacted security, including plains area. This study aimed to calculate rate analyze its impact on security area from 2005 2020. The primary materials needed are administrative maps, Landsat 7 8 images, productivity data, population consumption per capita data. With tools used is Google Earth Engine (GEE), SPSS 25,...

Abstract Sand traps in irrigation networks are typically used mitigating canal sedimentation. In located basins of high sediment yield due to the presence volcanoes, it is essential assess vulnerability sand traps. Using at scheme inlets, trap can be evaluated. This study aims understand throughout Progo–Opak–Serang (POS) Volcanic River Basin, Indonesia, via mapping distributions basin. We employed Revised Universal Soil Loss Equation estimate soil loss, where results show that average loss...

Surface irrigation networks in Indonesia are damaged by several factors, and sedimentation is among the most severe challenges. Sand traps play a substantial role improving system efficiency reducing sedimentation. There two periods sand trap operation: operational maintenance periods. Pengasih one of schemes implemented Progo Opak Serang (POS) River Basin, which has high level erosion. This study aimed to propose an appropriate management strategy for as first barrier network based on...

Terdapat lima pilar dalam penyelenggaraan tata kelola jaringan irigasi, salah satunya adalah perbaikan sarana dan prasarana irigasi. Perbaikan irigasi terbagi menjadi dua kegiatan, yaitu pengembangan pengelolaan. Terkait dengan kegiatan tersebut, terdapat banyak lokasi pada daerah yang memerlukan penanganan terlebih dahulu. Penelitian ini bertujuan untuk menganalisis prioritas sepuluh kewenangan kabupaten tersebar di D.I. Yogyakarta optimalisasi pelaksanaan pengelolaan Analisis data...

Abstract This research was aimed to measure actual evapotranspiration, determine of water requirement and crop coefficient (Kc) longan (Dimorcapus Lour.) cultivated in Longan Nawungan orchard, Selopamioro Village, Imogiri Sub-district. Plot scale balance applied ETa, with input components were rainfall irrigation, while output storage (ΔSM), surface runoff (SRO). Components measured using tank the moisture content gravimetry method. Automatic weather station installed orchard record...

Volcanic eruptions transport substantial amounts of sediment into river systems. It damages irrigation structures that depend on the nearby for water delivery, reducing conveyance efficiency. This study aims to propose an efficient approach management sand traps as main barriers in networks within Progo-Opak-Serang (POS) Basin. is accomplished by a measurable approach: mathematical framework executed with Hydrologic Engineering Center's River Analysis System (HEC-RAS). focuses selected...

Abstract After New Yogyakarta International Airport (NYIA) opening, Kulon Progo continues to develop, one of which is The Bedah Menoreh route project passes through the mountainous region. development encourages agricultural land conversion, impacts food security in Progo, especially This study aims identify conversion region Regency 2005 – 2020 and analyze its impact on regional security. method used a Normalized Difference Vegetation Index (NDVI) Landsat Imagery using Machine Learning...

Abstract Agricultural land-use changes can cause a reduction in the green open space area, thereby reducing infiltration and increase surface run-off. One of phenomena agricultural as indicated by addition percentage irrigation paddy fields Cereng Catchment Area (CA) 2.31%, 2.94%, 4.39%, respectively, 1995, 2008, 2018. Besides, settlement area plantation area’s were also change. The impact these is associated with curve number (CN) direct analysis conducted on relationship between effective...

Abstract The aim of this study was to measure actual evapotranspiration and determine water requirement crop coefficient (Kc) soursop (Annona muricata L). farmed at Nawungan orchard in Selopamioro village, Imogiri sub-district. Village monographs, 1: 25,000 scale Indonesian earth map climate data were used get the purpose study. An Automatic Weather Station (AWS) installed record rainfall, air relative humidity, wind velocity, solar radiation, as well soil moisture every fifteen minutes. A...

Abstract Sand trap is a part of the main building irrigation system. Its function to settle sediment that carried away from river stream. needs be flushed periodically with an optimal and efficient mechanism. This research aimed evaluate flushing efficiency sand Pengasih Weir. The data consisted bedload samples along channel trap’s existing mechanism data. results showed most dominant grain in Weir was fine diameter between 0.075 0.425 mm 77.2%. includes uniform well-graded because Cu Cc...

Abstract One Belt Road (OBOR) is an initiative of collaboration and development that was put forward by China. Moreover, the agricultural production in most country members confronted Water scarcity climate change. In current study it has been used Footprint (WF) as tool for measuring water consumption China participating country. Thus, this paper aims to understand OBOR from perspective WF products. On whole, results showed agriculture’s countries increased steadily about 6.84 trillion m 3...
