Abstract

The objectives of this research are to identify and evaluate the erosion in the catchment area of Way Rarem Dam, by predicting the magnitude of erosion using the Universal Soil Loss Equation (USLE). The outcome of this activity is the maps of erosion potential Catchment Area of Way Rarem Dam , which can be used as a guide in planning further handling. The field survey was conducted to cross check the locations suspected of having land use changes quickly in order to update data that already exist in accordance with current conditions. Calculation of the amount of erosion prediction using USLE equation is A = R x K x LS x CP. Based on the results obtained map making extensive catchment (Catchment Area) Reservoir Way Rarem namely 32864.8 ha (328.648 km ), which consistsof a class of very severe erosion very weight level covering 104.461 km2 (31.78%), weight level measuring 89.998 km 2 ( 27.38%), middle level mesuring 38.856 km (11.82%), light level measuring 92.262 km2 (28.07%), and very light level measuring 3,071 km (0.95%). The average rate of erosion in the catchment reservoirs Way Rarem which amounted to 238.33 tons/ha/year, which is classified in class IV of erosion levels or weight category.Keywords: erosion hazard level, catchment area

Abstract

Flow system engineering using box culvert had done in arterial road Soekarno Hatta section Untung Surapati-Hajimena, precisely on the Way Kandis river channel. As population growth, on the box culvert’s upstream, had frequently been flooding when it rains with high intensity. It could predict that run off discharge was increased as an impact increasing runoff coefficient due to the growth of the built area in its upstream. It indicated that the box culvert dimension is not suitable to serve runoff discharge. Therefore the evaluation is needed to assess whether the dimension of box culvert was still capable of serving the flowing runoff discharge. The existing box culvert dimension could not serve the runoff discharge in 10, 20, and 25 year return periods are 10.13 m3/s, 11.07 m3/s, dan 11,37 m3/s.It was recommended to use precast concrete (n = 0.03)and 0.015 in slope.The evaluation shown that to serve runoff discharge in 10, 20, and 25 year return period, minimum needed box culvert with dimensions are 1.9 x 1.9 (m), 2.0 x 2.0 (m), and 2.0 x 2.0 (m). Refer to it, then recommended the dimension of box culvert is 2.0 x 2.0 m. It could install more than one with an adjustment dimension if the slope were difficult to reach in the recommended dimension Keywords: river, flood, discharge, box culvert.

Abstract

The Bandar Lampung coastal area naturally has the potential of a tsunami hazard. Historically the coastal area of Bandar Lampung City had been hit by a tsunami with a height of 10-30 meters in 1883 when the eruption of Mount Krakatau occurred. The partial collapse of Mount Krakatau, which occurred at the end of 2018, also had a tidal wave impact as high as 1-2 meters in the Bandar Lampung coastal area. This study aims to produce Thematic Maps of Tsunami Hazard Zones in the Coastal Areas of Bandar Lampung City as a source of information for the community and stakeholders. The method used is spatial analysis with GIS through the overlay method. The result shown that eight sub district in Bandar Lampung City are prone to tsunami hazards with risk categories up to very high risk categories.

Abstract

Keterbatasan sumber daya air menjadi salah satu kendala utama dalam peningkatan produktivitas pertanian di Indonesia, termasuk di Kabupaten Tulang Bawang Barat. Sebagian besar petani hortikultura di wilayah ini masih mengandalkan curah hujan musiman dan penyiraman manual, sehingga berisiko mengalami penurunan hasil panen terutama pada musim kemarau. Untuk menjawab permasalahan tersebut, kegiatan pengabdian kepada masyarakat ini difokuskan pada transfer teknologi pemanenan air hujan (Rainwater Harvesting) yang diintegrasikan dengan sistem irigasi cerdas hemat air (smart irrigation). Metode pelaksanaan dilakukan secara partisipatif melalui enam tahapan, yaitu sosialisasi dan pemetaan kebutuhan, pelatihan teknis dan manajerial, implementasi teknologi, pendampingan dan monitoring, evaluasi, serta penyusunan strategi keberlanjutan. Implementasi teknologi meliputi pembangunan sistem pemanenan air hujan berkapasitas 5.000 liter, penerapan irigasi cerdas di instalasi hidroponik, serta integrasi sensor IoT untuk monitoring kualitas dan ketersediaan air. Hasil kegiatan menunjukkan peningkatan signifikan pengetahuan peserta, dengan rata-rata nilai pretest 42,3 meningkat menjadi 84,7 pada posttest. Secara teknis, sistem yang diterapkan mampu menampung rata-rata 4.200 liter air hujan per bulan, menghemat penggunaan air hingga 43%, dan meningkatkan produktivitas hortikultura sekitar 25% dibanding kondisi awal. Kesimpulannya, penerapan teknologi pemanenan air hujan dan smart irrigation terbukti efektif dalam meningkatkan efisiensi air, produktivitas pertanian, serta kapasitas kelembagaan petani.
