Abstract

Kerusakan dan kerugian terbesar yang diakibatkan oleh gempa Lombok tahun 2018 di Kabupaten Lombok Utara adalah sektor permukiman yaitu sebesar 72,43 % dengan total rumah rusak sebanyak 63.332 unit. Desa Karang Bajo adalah salah satu desa di Kecamatan Bayan Kabupaten Lombok Utara dimana terdapat cukup banyak rumah warga yang mengalami kerusakan dengan katagori sedang dan berat pasca gempa tahun 2018. Permasalahan yang ditemui bahwa masih banyak masyarakat yang belum mengetahui bagaimana cara membuat bangunan yang lebih tahan terhadap gempa ditinjau dari aspek struktural. Disisi lain, potensi tanaman bambu di Kecamatan Bayan cukup banyak namun pemanfaatannya belum optimal khususnya untuk membuat rumah yang aman dari gempa bumi. Dengan demikian penyuluhan tentang pembangunan rumah dari pasangan batu maupun rumah dari bambu plester yang tahan gempa ini sangat relevan dengan kebutuhan masyarakat di Desa Karang Bajo. Metode kegiatan yang dilaksanakan dikemas dalam bentuk demo dan penyuluhan. Demo dilakukan untuk menjelaskan secara langsung bagaimana cara membuat rumah dari pasangan batu dengan struktur beton bertulang dan rumah bambu plester yang tahan gempa. Adapun kegiatan penyuluhan ini dibagi menjadi beberapa tahap yaitu persiapan penyuluhan, pembuatan materi dan gambar-gambar desain sebagai alat bantu penyuluhan, koordinasi dengan Kepala Desa dan menentukan jadwal dan lokasi/tempat penyuluhan. Dari hasil penyuluhan terlihat bahwa masyarakat desa Karang Bajo telah mendapatkan informasi dan pengetahuan tentang bangunan sederhana tahan gempa dari beton bertulang dan bambu plester. Dengan pengetahuan yang dimiliki diharapkan dapat ditularkan kepada keluarga dekat dan masyarakat disekitarnya

Abstract

Test efforts to find alternatives to increase the even distribution of irrigation water on service land. The results of previous research conducted by researchers show that drip irrigation which is designed in stages with a water source from a drip irrigation tank using two types of emitters in a multi-stage drip irrigation system provides different irrigation water distribution results, so it is necessary to find a solution. so that irrigation can occur evenly. To get an alternative that might be tested is to use several types of emitters in the PVC pipe drip point holes, because these tools already exist on the market. This research aims to determine the effect of using two types of emitters, namely 2 lt/min and 4 lt/min emitters on distribution of irrigation water in a 4-tiered drip irrigation network. The test data analyzed includes irrigation distribution data, flow discharge data and irrigation uniformity (Cu), and the results of the analysis are presented in the form of tables and graphs and discussed before conclusions are drawn. The analysis results show that the average Cu for the two types of emitters is above 97%, which is very good and the two emitters have a very even distribution. The difference in distribution volume for each emitter, for a 2ml/min emitter is around 1ml -2 ml and for a 4 ml/min emitter it is 1ml -2 ml, with an irrigation network flow rate of around 84ml/min – 99.7 ml/min.

Abstract

Mataram as the capital of West Nusa Tenggara Province has attracted people to live in it. The small city of Mataram makes the surrounding area a buffer area for rapid development. This condition can be seen from the increase in housing around Mataram City. This increase in housing area causes a reduction in water catchment areas. So during the rainy season there is an increase in runoff. The aim of the research is to determine the effect of an environmentally friendly drainage system on the amount of runoff discharge. The data required is land use data, rainfall, location maps and soil data. Rainfall data is used for Intensity Duration Frequency (IDF) analysis. IDF curves and land use data are used for runoff discharge analysis. Soil data is used to determine permeability which is used to determine of the discharge of infiltration well. Next, analyze the effectiveness of infiltration wells as an environmentally friendly drainage system. The results of the research show that there has been an increase in residential area over the last 10 years by 58% in Labuapi District, the southern part of Mataram City, 25% in Lingsar District and 29% in Gunungsari District, which is in the northern part of Mataram City. Changes in land use resulted in an increase in runoff discharge of 21% in Labuapi District, 8% in Lingsar District and 15% in Gunungsari District. An infiltration well with a diameter of 1 m and a depth of 1 m can absorb 1.13 m3 of water in the southern part and 1.21 m3 in the northern part of Mataram City. If every 100 m2 of residential area there is one infiltration well, then the effectiveness of the infiltration well in reducing flood runoff is 17.71% in Labuapi District, 15.61% in Lingsar District and 23.35% in Gunungsari District.

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.
