Abstract

Drought occurs quite often in Indonesia, closely related to water availability for community needs. One of the districts in West Java Province experiencing drought problems is Karawang district, where the RWH (Rainwater Harvesting) concept will be applied. This study aimed to analyze the risk of drought-related to applying the potential RWH in reducing drought risk. This study only focuses on meteorological drought, determined by SPI (Standardized Precipitation Index). Identification of potential areas for the application of RWH is carried out using the Weighted Method Overlay approach in the Geographic Information System (GIS), which was modified by adding a parameter of potential drought hazard. The potential reliability of RWH, as seen from Volumetric Reliability (VR) for supplying the average water requirement of MCK (Bath Washing Toilet) per year, indicates that most of the Karawang district area is potential for applying RWH. The results of adding the potential drought hazard parameters on applying the RWH concept show the decreasing area of very potential and potential category areas into 5,38%, the increase of drought resistance capacity is 17.5%, and the risk-reducing to 8.3%. Those results are due to the changes in the area of drought in the risk analysis. The assumptions of 60 rainy days on the average rainy day in a year and all households making RWH storage systems were used in the analysis. The results of this study can be used as a first step to see the potential of RWH in Karawang Regency both in terms of area and reliability.

Abstract

ABSTRACT Over the past ten years, flooding has been the most frequent problem in South Sumatra Province, Indonesia. As the capital of South Sumatra Province, Palembang City faces similar problems, where Lambidaro Watershed is the watershed with the highest 25-year potential flood discharge in Palembang City. One of the causes of flooding is the lack of river channel capacity related to land erosion in the watershed. This study aims to learn the prediction of sediment volume and efforts to reduce it in the Lambidaro watershed, Palembang City. This study uses two types of modeling, namely numerical models and empirical models. The numerical model uses the HEC-RAS 6.3.1 application, while the empirical model uses the USLE and SDR equations. The input parameters of the numerical model use some data derived from field measurements. The sediment concentration and observation discharge parameters were measured three times in September 2022. The grain size distribution parameters were sampled at three locations each once in August 2022, and the cohesive parameter was sampled at one location twice in August 2022. The result of the prediction of sediment volume by the numerical model is 1,421.86 m3/year. In contrast, the result of the prediction by the empirical model is 476,941.25 m3/year. Efforts to reduce the prediction of sediment volume USLE method are in the form of applying the intercropping method. The results of the conservation study show that the efforts made can reduce the volume of sediment by 17%.Keywords:       sediment, flood, conservation, intercropping, Lambidaro,  ABSTRAKSelama sepuluh tahun terakhir, banjir telah menjadi masalah yang paling sering terjadi di Provinsi Sumatera Selatan Indonesia. Sebagai ibu kota provinsi Sumatera Selatan, kota Palembang menghadapi masalah serupa. dimana DAS Lambidaro adalah DAS dengan potensi debit banjir kala ulang 25 tahun tertinggi di kota Palembang. Salah satu penyebab banjir adalah penurunan kapasitas alur sungai yang berkaitan dengan erosi lahan di DAS. Penelitian ini bertujuan untuk melakukan kajian prediksi volume sedimen serta upaya pengurangannya di DAS Lambidaro. Penelitian ini menggunakan dua jenis pemodelan yaitu model numerik dan model empirik. Model numerik menggunakan aplikasi HEC-RAS 6.3.1 sedangkan model empirik menggunakan persamaan USLE dan SDR. Parameter input dari model numerik menggunakan beberapa data yang berasal dari pengukuran lapangan. Parameter konsentrasi sedimen dan debit sesaat diukur sebanyak tiga kali pada bulan September tahun 2022. Parameter gradasi butiran diambil sampelnya masing – masing pada tiga lokasi sebanyak satu kali, dan parameter kohesif diambil sampelnya pada satu lokasi sebanyak dua kali pada bulan Agustus tahun 2022. Hasil prediksi sedimentasi dasar sungai model numerik adalah 1.421,86 m3/tahun sedangkan hasil prediksi volume sedimen model empirik adalah 476.941,25 m3/tahun. Upaya mengurangi prediksi volume sedimen metode USLE berupa penerapan metode tumpang-sari. Hasil kajian konservasi menunjukkan upaya yang dilakukan dapat mengurangi volume sedimen sebesar 17%.Kata Kunci:             sedimen, banjir, konservasi, tumpang-sari, Lambidaro

Abstract

The morphology of river mouths is influenced by several factors, including waves, river discharge, tides, currents, and those caused by human intervention. This study explores the dynamics of erosion and sedimentation processes in the estuary of the Ayung River caused by lithology, wind, tides, currents, and waves. This study aimed to determine the effect of river discharge, tides, currents, and waves on erosion and sedimentation in the waters of the Ayung River Estuary. Hydrodynamics and sediment transport modeling using Delft 3D software. As a validation of the modeling results, a calibration was performed on the results of hydrodynamic parameter measurements that had been carried out previously. The review conditions are divided into the rainy season (December – March) and the dry season (April – November). River discharge, tides, currents, and waves affect littoral processes on the shoreline around the waters of the Ayung River. This influence causes erosion and sedimentation around the coastal area and affects sediment transport both in the rainy and dry seasons.

Abstract

Floods are the dominant color of the interaction of human activities and natural mechanisms that occur every year in the city of Jakarta. Various efforts have been made to reduce flooding in Jakarta, but flooding is still the dominant color, especially on the banks of the Ciliwung River. On the banks of the Ciliwung River, Tebet, Matraman and Jatinegara sub-districts are the three areas that experienced the most severe overflows of the Ciliwung River. Flood mitigation efforts in these three areas have been carried out in the form of increasing the drainage capacity of the Manggarai Gate and normalizing the river in the form of dredging and construction of embankments. However, this effort is not optimal because the implementation of normalization is hampered by social conflicts. This paper discusses mitigation efforts in the form of normalization and combination with retention ponds which are carried out by simulating flooded areas. Completion of the normalization of the Ciliwung River is not the best solution to deal with flooding in Jakarta. The flood volume which usually occupies the flood area flows quickly due to changes in the geometry of the river and causes changes in the hydrograph peak and causes flooding in the downstream part of the study area causing an increase in inundation area in Manggarai up to 200%. On the other hand, the use of retention/storage ponds on limited land has been able to reduce flood inundation by 10%. Therefore, staging in the planning and construction of flood mitigation infrastructure needs to be considered and planned thoroughly.
