Abstract

Desa Medana Kecamatan Pemenang merupakan salah satu Desa di Kabupaten Lombok Utara dengan potensi lahan yang dimanfaatkan untuk tanaman keras. Tanaman Coklat dan kelapa sebagai produk unggulan hasil perkebunan masyarakat. Hasil panen dari perkebunan adalah musiman sehingga kebutuhan sehari-hari masyarakat seperti sayur harus dibeli dari pasar setempat. Sistem irigasi yang digunakan saat ini masih berorientasi pada sistem tradisional dimana air yang digunakan sangat boros. Masyarakat umumnya belum banyak mengetahui tentang sistem irigasi hemat air untuk jenis-jenis tanaman musiman. Sistem irigasi hemat air sangat cocok diterapkan pada wilayah yang memiliki sumber daya air terbatas. Irigasi tetes, pancar maupun sistem irigasi bawah permukaan sangat tepat untuk diterapkan diwilayah kering dengan jenis tanaman musimam. Tanaman yang dibudidayakan dapat berupa tanaman untuk kebutuhan sehari-hari seperti bayam, kangkung, sawi, sayur hijau, pacoy dan tanaman lainnya. Sistem irigasi hemat air ini sangat mudah dibuat dan operasionalnya juga sangat mudah. Kegiatan pengabdian masyarakat ini dilaksanakan untuk memperkenalkan pembuatan sistem irigasi vertical di Desa Medana. Dengan kegiatan ini diharapkan masyarakat di Desa Medana dapat memahami dan mampu membuat jaringan irigasi irigasi hemat air. Sehingga diharapkan masyarakat dapat memanfaatkan pengetahuannya untuk meningkatkan lahan pekarangan yang kurang produktif menjadi lahan yang produktif yang dapat berproduksi untuk memenuhi kebutuhan masyarakat sehari-hari. Hasil sosialisasi menunjukan bahwa Masyarakat desa Medana mempunyai semangat yang sangat tinggi untuk menerapkan berbagai teknologi irigasi hemat air.

Abstract

Soil moisture is the most important part of irrigation activities, because it is the result achieved by providing irrigation on a particular land. Likewise, with the application of drip irrigation, soil moisture is also the purpose of irrigation in the planting medium. In multilevel drip irrigation sistems, the potential for soil moisture produced by the irrigation sistem is very important to pay attention to, because the size of the moisture that can be provided will affect the scheduling of the drip irrigation provided. And therefore the ability of an irrigation sistem to provide optimum soil moisture in a particular medium deserves attention, before the sistem is applied to farming activities. For this reason, this test aims to determine the ability to provide soil moisture in a drip irrigation sistem that uses a 4 liter/hour emitter in a 4-tiered drip irrigation network, a polybag planting medium and an irrigation duration of 5 minutes to 20 minutes. The test data analyzed is irrigation and soil moisture distribution data, then the results of the analysis are presented in tabular form and discussed and conclusions are drawn. The test results show that the distribution of drip irrigation water occurs evenly with the optimal application of 41% moisture, and with the application of additional soil moisture of around 6% -7% for an irrigation duration of 20 minutes. The daily decrease in soil moisture that occurred during the three days of testing was found to be around 2% as a result of evaporation

Abstract

Changes in land use that have occurred over a period of several years in the Kuta area have resulted in a lack of water catchment areas. The impacts caused by the lack of catchment areas are flooding and reduced water quality in rivers. The flood disaster in the Bengkang River caused damage to bridge infrastructure and people’s homes. The Bengkang river basin is divided into 3 sub – basins with a total area of 10,45 km2. Based on the results of the design flood analysis using the Nakayasu synthetic unit hydrograph method, the largest flood discharge value was obtained, namely 32,859 m3/second for a return period of 25 years. Hydraulic modeling was carried out to determine the water level and the ability of the river section to receive flow using HEC-RAS 6.1 software. Based on the simulation results with a return period of 5 years, it is known that flooding occurs in the middle and lower reaches of the Bengkang River, so structural mitigation is needed, namely normalization and repair of embankments. A 25-year return period flow simulation was carried out using a cross – section of the channel plan and no runoff was obtained in the Bengkang River.
