Abstract

This research was conducted to find out the availability of water to the requirements of water and also predict flood plan discharge for return period based on hydrological analysis in Comal River.Calculations are carried out using rainfall data obtained from PUSDATARU of Pemali - Comal from 1999 - 2017.Used the rainstation in the region of Comal Watershed, there are 7 rain stations. Catchment area of rain station used Thiessen Polygon Method to know value of catchment area of each rain station. The Gumbel distribution (Generalized Extreme Value distribution Type-I) is used to model the distribution of the maximum (or the minimum) of a number of samples of various distributions. The calculation of the flood discharge design is using the Nakayasu, Rational, Weduwen, Weduweden, and Haspers method.Based on the result of this research it can be concluded that the biggest water potential occurs in January is 199.60 m3/s and the smallest in August is 0.84 m3/s. Cropping pattern carried out with one year there are three cropping patterns, namely paddy - paddy - secondary crops. For the water requirements, enough can be fulfilled, but in August and September, where the planting period III for the secondary crops experiences a deficit. The method used to design flood discharge is the Nakayasu method. For the embankment construction and normalization is profitable.Keywords: River, Flood, Embankment, Thiessen, Comal ?

Abstract

ABSTRACTThe pile foundation is one of a kind of deep foundation that serves to funnel structural loads to hard soil layers that have a high carrying. The purpose of this study was to calculate the bearing capacity of piles.Based on SPT data obtained and calculated by Mayerhoff method at point BH-01 Qult = 259,992 tons, at point BH-02 Qult = 258,234 tons, and at point BH-03 Qult = 279.586 tons, with HSPD data obtained based on reading dial pressure manometer tool is approximately from 178,365 tons - 186,120 tons, whereas with PDA obtained based on RMX value on PDA test is about 124 tons - 225 tons.The results of the calculation of bearing capacity there are differences in values, both from the use of calculation methods and the location of points reviewed. From the results of the calculation can be concluded that the big highets bearing capacity the pile is values of SPT. In values of HSPD and PDA is relative same because the method using similar method (hydraulic and wave method).

Abstract

ABSTRACTRivers drain water by embracing a gravitational philosophy, in which water always flows from high to low or downstream to downstream. The process of river water flow is an endless natural process, closing the hydrological cycle by restoring the river runoff to the sea. For centuries, rivers have been used as a source of clean water, meeting human needs for drinking water, sanitation, irrigation, and so on. Large rivers are dammed to store water in the wet season and use it in the dry season for various purposes.Kali Gung or Kaligung or also known as Kaligung river is a river that flows in Tegal regency, Central Java. This river is one of the largest rivers in Tegal besides Kali Ketiwon and Kali Kemiri. This river is called Kali Gung because it is tangent to the spring that comes from Mount Agung is an ancient name from Mount Slamet in pre-Islamic times in Java. Upstream or spring water Kaligung located in the north of Mount Slamet and empties to the north precisely in the sea of Java.Keywords: Hydrologycal cycle, rivers, downstream, upstream, Kaligung.

Abstract

Bintan island is one of the big island in the Province of Kepri. The topographical condition of the Bintan is flat, which is difficult to convey water gravitate. Therefore the water management requires a storage. Fortunately some lakes were formed due to the boxit mining In Bintan. The lake area is about of  5 hectares and with 20 depth can be used as a storage for  water drinking and then distributes water using pump.  There were  two lakes identified as storage to fulfill water requirement for the west part of Bintan island. The total area of lakes is about 12 hectares and 20 m depth in average. Hydraulic structures, such as canal and water intake were design with method of “Bernoulli”. Analysis showed that the two lakes can be operated with 1 million m3 live storage and will serve 40.000 of people. Hydrological analysis showed that the dry month were occurred on February, March, Augustus and September.  Futher more those two lakes had potentially operated volume about 7 million m3 per year. As conclusion the two lakes can be used to fulfill the water requirement for the west part of Bintan Island. The location of water intake was proposed on Jago river and convey the water gravitate to the two identified lakes. Keywords: Bernoulli, Bintan Island ABSTRAK Pulau Bintan yang terletak di Propinsi Kepulauan Riau menghadapi kendala penyediaan air baku karena kondisi topografi Pulau Bintan relatif datar sehingga tidak memungkinkan pembuatan waduk yang dapat mengalirkan air secara gravitasi.  Sedangkan pemanfaatan air permukaan atau air hujan harus ditampung untuk menjamin ketersediaan air setiap saat.  Di P. Bintan terdapat beberapa danau buatan yang masing-masing luasnya dapat mencapai puluhan hektar dengan kedalaman mencapai 25 meter.  Danau tersebut dapat dipergunakan untuk menampung air yang tentu pengalirannya ke pemukiman harus menggunakan pompa. Untuk merencanakan penampungan air yang paling memungkinkan ditinjau dari aspek teknis, e.konomis maka dilakukan penelitian dan perencanaan. Terdapat dua danau di P. Bintan bagian barat yang sangat sesuai untuk tampungan air untuk penyediaan air baku Kecamatan Bintan Utara. Kedua danau tersebut yang masing masing mempunyai luas masing masning lebih kurang 10 hektar dengan kedalaman 20 m dapat disuplai dari Sungai Jago. Metodologi perhitungan pengaliran air dari sungai Jago ke kedua danau tersebut dihitung menggunakan rumus hidrolika “Bernoulli”. Hasil perhitungan menunjukan bahwa potensi kedua waduk tersebut dapat menampung lebih dari satu juta m3, yang dapat memenuhi kebutuhan air baku kecamatan Bintan Utara dengan penduduk sebanyak lebih kurang 40.000 jiwa, selama dua bulan kering yaitu bulan Februari, Maret, Agustus dan September. Hasil kajian juga menunjukkan bahwa potensi air dalam setahun lebih kurang sebesar 7 juta m3. Kesimpulan pemenuhan kebutuhan air baku untuk Pulau Bintan bagian barat dapat dipenuhi dengan memanfaatkan dua buah waduk untuk menampung air dari sungai Jago dan untuk mengalirkan air dari sungai Jago ke dua waduk tersebut dapat dilakukan dengan cara gravitasi.

Abstract

This paper describes the development and application of a transfer hydrograph approach to flood forecasting on the Cimanuk River at the city of Jatigede in West Java, Indonesia. The Transfer Hydrograph (TH) is a transfer function that transforms total rainfall into a flood hydrograph at the basin outlet. As opposed to the conventional unit hydrograph approach which uses effective rainfall and direct runoff, the transfer hydrograph uses the total rainfall and the direct runoff at the basin outlet. The Cimanuk river basin (drainage area : 1,442 km2) has four sub basins. It was found to be necessary to further extend the application of the transfer hydrograph concept to include all channel routing effects. This because the rainfall at each subbasin was found to be quite independent of the rainfall at other sub basins, and run off data were only available at the basin outlet at Jatigede. Using the available data, transfer hydrograph were derived for each sub basin and later combined to give the runoff hydrograph at Jatigede. The approach was tested against recorded rainfall-run off data at Jatigede and was found to give very reasonable results. For flows above 300 m3/second, the maximum error of prediction was less than 12 %.
