Abstract

Bekasi is one of the regions in Indonesia that often suffer from flooding. To overcome flooding problems in the Bekasi area, the Ciliwung Cisadane River Basin Center has begun a normalization project along the Bekasi River. This research aimed to evaluate the Bekasi River's cross-sectional capacity both before and after normalization. The analysis focused on the section where the Cileungsi and Cikeas rivers converge to the Bekasi weir. In this research, secondary data were employed, such as national digital elevation model data, detailed engineering designs of Bekasi River flood control activities, and rainfall data from the Cibinong Station that covers the period from 2006 to 2020. The result from planned flood discharge with the Nakayasu synthetic unit hydrograph method for a return period of 25 years on the Bekasi River was obtained at 665.81 m3/s. The results of hydraulic analysis before normalization with the HEC-RAS application show that flooding occurred at 102 out of 116 stations, with capacities of river cross-sections ranging from 453.49 m³/s to 665.71 m³/s at these overflow stations. Following the river normalization process, the cross-sectional capacity at all Bekasi River stations can accommodate flood discharge without any instances of overflow.Keywords: Flood, HEC-RAS, Nakayasu, Normalization, Rainfall.

Abstract

The population growth implies that the population's need for clean water tend to increase. Clean water availability is not optimal due to geographical factors and discharge reductions during dry season. This research was conducted to design spring water catchment building and water distribution system at Kalikajar Village, Wonosobo. The population data, water demand, and spring discharge were utilized in this research. The population growth was calculated with arithmetic, geometric, exponential, and logistic method. Then water demand was calculated based on SNI 19-6728.1-2002.  The population growth which predictably reaches 5328 people in 2050 will result in increasing clean water demand by 9.68% with domestic water demand of 4.63 L/s. The spring discharge measured at the research location showed an average of 10.80 L/s. Therefore, the spring discharge is able to meet the population needs in the projected year. The spring catchment building was designed with Type B, while three reservoir were designed with the capacity of 7 m3 each. The water distribution is designed with gravity system because the elevation difference between the spring and the village is more than 10 m. The PVC pipeline used diameter of 100 – 150 mm, with total length of 11843 m. The design meets the calculated requirement and could be implemented. Keywords:  Distribution system, Reservoir, Spring water, Hilly areas, Water consumption

Abstract

Bogor Agricultural University (IPB) Campus is an urban area that experienced flooding when heavy rain occurred, especially at Graha Widya Wisuda (GWW)’s parking lot, Kamper Street (FEMA), Meranti Street, and Tanjung Street. The drainage system of IPB campus is a conventional system. It drain surface runoff as fast as possible to the outlet. Zero Runoff System (ZROS) is one of technologies to minimize runoff using water storage. The advantages of ZROS are runoff minimization, local aquifer’s recharge, and damage mitigation on public facilities. This research aimed to design ZROS at IPB Campus that capable to minimize surface runoff. This research started by water catchment area (WCA) delineation, design rainfall and peak runoff analysis, infiltration rate measurement, and ZROS design calculation. Based on frequency analysis the design rainfall was 125.68 mm. Sub-sub-WCA 1-1C (3 locations), 1-1B, 2-1B, and 2-2A were the flooding’s location. Water pocket is the proposed technology to be applied in ZROS. To mitigate flooding, sub-sub-WCA 1-1B, 1-1C, 2-1B, and 2-2A needed 44 units of water pockets with length of 1.20 m (sub-sub-DTA 1-1B, 2-1B, dan 2-2A) and 1.60 m (sub-sub-DTA 1-1C),  with depth ranged from 2.41 m to 3.40 m. Keywords: drainage, flood, runoff, water balance, ZROS

Abstract

Bogor is a city with a high rainfall. Bogor has the average monthly rainfall of 267.3 mm with an average of 16 days of rain per month. This research purpose are to identify the condition of the existing drainage channels and to analyze the magnitude of runoff discharge compliance with existing drainage channels capacity. This research was conducted from May to August 2017 in Dramaga Cantik 2, Bogor, West Java, were analyzed using EPA SWMM 5.1. Based on the rainfall data processing of Dramaga area, Bogor, this research used distribution method of Log Pearson III. The result showed that maximum rainfall was 129.722 mm. The result of EPA SWMM 5.1. simulation showed that drainage channel capacity could accommodate the runoff, but channel C24 was overflow. It was suggested to improved channel width to 0.42 m with cost of Rp 2,368,393.00.Keyword: drainage channel capacity, EPA SWMM 5.1, rainfall, runoff

Abstract

Perubahan tata guna lahan dapat mempengaruhi suplai air suatu area. Kapasitas simpan air adalah salah satu aspek dalam studi neraca air yang menunjukkan ketersediaan air. Penelitian ini bertujuan menghitung potensi suplai air dan menganalisis kapasitas simpan air di Kecamatan Cibinong. Penelitian ini berlangsung sejak April-Juli 2017. Data yang digunakan antara lain data iklim, kepadatan penduduk, dan peta tata guna lahan. Perhitungan dilakukan dengan metode Penman-Monteith menggunakan software CROPWAT. Analisis peta tata guna lahan Kecamatan Cibinong menunjukkan terjadi penurunan kapasitas simpan air di Kecamatan Cibinong, dari 70.01 mm menjadi 64.54 mm sejak tahun 2013 hingga 2015. Rasio supply/demand sebesar 0.14 menunjukkan daya dukung lingkungan berbasis neraca air (DDL-air) terlampaui (overshoot). Peningkatan DDL-air dapat dilakukan dengan pembangunan sumur resapan dan perluasan RTH. Kata Kunci: evapotranspirasi, kapasitas simpan air, tata guna lahan

Abstract

Drainage system is one of the important infrastructure components to drain runoff from rainfall. The purpose of this research were to identify the condition of existing drainage system in Alam Sinar Sari Residence, to analyze the discharge using EPA SWMM 5.1 application, and to analyze the suitability of existing drainage system with its runoff. The research was conducted since March 2018 on Alam Sinar Sari Residence which is located in Cibeureum Petir, with the total area of 15 ha. Based on analysis and statistic test, the acceptable distribution model is Log Pearson III model with 5 year return period. The rainfall designed was 175.86 mm. Based on simulation done using SWMM 5.1, the actual debit of conduit C76 were bigger than its planned debit and should be re-evaluated. Conduit C76 had dimension of depth of 0.31 m and width of 0.34 m. Based on simulation the discharge in C76 of 0.088 m3/s was bigger than the planned debit which was only 0.069 m3/s. After evaluation, conduit C76 should undergone changes of width dimension from 0.34 m to 0.50 m to be able to hold runoff.Keywords : designed rainfall, drainage, EPA SWMM 5.1, runoff

Abstract

Land use change have an impact on infiltration capacity. There is often an annual flood on Kadumanggu District. When the rainfall is high so the river will be overflow. The outlet of Cikeas sub-basin was located on Kadumanggu District. This research aimed to determine the maximum discharge of the Cikeas River and analyze the relation between land use change and discharge of Cikeas River. The research was conducted by delineating the water catchment area, analyzing rainfall, making a land use map and modeling with HEC-HMS. Based on the modeling results, the maximum discharge of the Cikeas River in 2000 was 74.3 m3/s, in 2009 was 84.9 m3/s, and in 2018 was 91.7 m3/s. The catchment area with an extensive use as residential had a higher river discharge compared to the area with a large green area. It meaned that, land use changes greatly affected the river discharge.
