Abstract

Kawasan Perumnas Kota Cirebon sebenarnya dulu diperuntukan untuk tempat daerah resapan air, akan tetapi masyarakat tetap melakukan pembangunan di wilayah tersebut. Oleh karena itu sangat wajar sekarang kawasan tersebut tergenang banjir. Genangan yang terjadi di kawasan Perumnas merupakan hal yang cukup memprihatinkan karena hampir setiap musim penghujan datang selalu tergenang banjir. Data-data yang digunakan pada penelitian ini adalah data curah hujan (15 tahun), peta lokasi, dan data pengukuran laju resapan air di kawasan perumahan. Tujuan dari penelitian ini adalah menganalisa besarnya reduksi limpasan dari air hujan di lokasi penelitian, sehingga dapat mengurangi beban saluran drainase yang ada dan sebagai salah satu suplesi air tanah yang ada dilokasi penelitian. Tahapan olah data mencakup analisis hidrologi dengan mencoba beberapa metode dalam menentukan debit banjir rencana. Dari beberapa metode yang dicoba, maka dipilih Metode Gumbel. Hasil yang diperoleh dilakukan analisa hidrologi didapat curah hujan 2, 5 dan 10 tahun sebesar 0,0034 m3/det; 0,0046 m3/det dan 0,0053 m3/det untuk analisa geoteknik pada lokasi fasum didapat 14,25% lempung; 83.75% lanau dan 2% pasir dan untuk lokasi rumah warga didapat 24,60% lempung; 63,40% lanau dan 12% pasir dan dari 1 buah sumur resapan yang dibuat di lokasi fasum dapat mereduksi air limpasan sebesar 12,81 % untuk periode ulang 2 tahun, 9,47% untuk periode ulang 5 tahun dan 8,22% untuk periode ulang 10 tahun. Reduksi air limpasan dengan menggunakan sumur resapan diharapkan dapat mengurangi beban saluran drainase yang ada dilokasi penelitian, sehingga peluang genangan/banjir pada saat hujan tidak terjadi/berkurang.

Abstract

Cibendung Weir comprised in the district of Banjarharjo Brebes Center Java, the located approximately less than 50 km from Cirebon and 40 km from Brebes Center Java, and exist some villages such as, Cikakak, Karang Maja, Tiwulandu Village in East and Tonjong, Singkup, Gandol in West.Cibendung Weir have duct the name is Induk Cibendung Weir or named D.I Jangkelok Hilir. At first, the water able to dilute more less 6677ha but in this time only more less 6349ha, the trouble is diversion of the use of land. This Cibendung Weir was built in the years 1901 – 1904.  The irrigation areas of Cibendung Weir supply six kemantren such as Kemantren Cibendung, Kemantren Bantarsari, Kemantren Losari Hulu, Kemantren Losari Hilir, Kemantren Kubangjero, and Kemantren Rungkang.The purpose of this research is become reference from evaluation performance of the irrigation area in Cibendung Weir by analyzing the physical condition of building although duct in the irrigation area of Cibendung Weir, analyzing of human resource in the irrigation area of Cibendung Weir, analyzing of rain Hydrology in the irrigation area of Cibendung Weir, analyzing of income from Bendung Cibendong, analyzing of the patterns plants in the irrigation area of Cibendung Weir, and analyzing planning plant and the realization of planting in the irrigation area of Cibendung Weir.The method of this research is qualitative method, in which the fission of the problem is explained that subject or the object research based on the facts which used during doing the research in performance of irrigation system and try to make a good relation in deep from the aspects particularly.Based on the build condition in this irrigation area is classified as satisfactory with percentage of damage reached 11,30%. Meanwhile, the duct condition in this irrigation area Cibendung Weir is good classified with percentage of damage reached 8,21%. The condition of organizer in DI Jangkelok Cibendung Weir only available 51 people, while in needed is 67 people with less percentage reached 17,94% so that service toward the duct condition is less completed and have the impact to net condition which less wake or always damaged, this situation should be increased.From the results of the analysis of the ratio of demand discharge with available discharge added effective rainfall in Irrigation Area Jengkelok,Cibendung Weir fulfilled,but many unused discharge it is necessary to modify cropping pattern in orde to maximize the potential of available discharge. The planting realization in 7 years ago in the irrigation area Jangkelok Cibendung Weir  it is less from the planning plant, but in the period of 2011/2012 occurs increased 7,34% and the realization of intensity planting is average 243,77% while the average of planning plan is 268,91% thus the lower plant in productivity in this case since it can’t be done to planting in this wide area.

Abstract

The perumnas gunung area is one of the areas in the Larangan sub-district, Harjamukti Subdistrict, Cirebon City, whose drainage system greatly disturbs the activities of the population in Cirebon City because when heavy rain causes the high volume of water in the drainage so that it comes out to the highway and is very disturbing it can also cause congestion.To solve the problem of inundation and flooding, it requires maximum rainfall data, population density data and hydraulic data from direct observation at the research location. From the rainfall data, the intensity of the rainfall is calculated, then the standard deviation is calculated to get the return period value using the Gumble formula. From the calculation of the Return Period, the calculation of the flood discharge is carried out using a rational method and calculating the discharge of the existing channel. Calculation of the capacity of the existing channel discharge is carried out by calculating the discharge of rainwater and discharge of household wastewater.From the calculation of Hydrology and Hydraulics, the value of Rainfall Intensity is 46.632 mm / day, the overall channel discharge = 0.603 m3 / s, the calculation of the total discharge from household wastewater and rainwater discharge for the 2-year return period is 0.0076 m3 / s. . From the calculation results, the authors conclude that the dimensions of the existing canal can still accommodate the flow of rainwater and household wastewater. The solution to overcome flood inundation on Jalan Ciremai Raya, it is necessary to normalize the drainage channel so that the drainage channel can function properly.

Abstract

The rain that fell in the city of Cirebon, especially the drainage on Jalan Pemuda, could not accommodate and drain the water so that it could create puddles on the roads and surrounding areas. Hourly rain intensity, planned flow rate and channel cross-sectional dimensions are the first steps for flood prevention. Hydrological analysis is used to calculate the discharge capacity of the drainage plan. The results were then analyzed the dimensions of the channel, the drainage ability to accommodate the falling rainwater where Qs is bigger than Qp. the channel discharge has not been able to accommodate the Q plan in the channel so that there will be a runoff of 17.759%. So to anticipate runoff, it is necessary to have a channel improvement plan of 33.477%. In addition to channel improvement solutions, arrange and define the boundaries of water storage areas by measuring and mapping boundaries and issuing regulations that prohibit or limit the construction of buildings that can reduce the ability of areas to store and absorb rainwater by referring to the basic building coefficient (KDB) permitted as stated in the RT/RW.

ABSTRAKWaduk Malahayu merupakan salah satu waduk buatan yang berada pada daerah aliran sungai Kabuyutan bagian hulu. Sejak Waduk Malahayu dioperasikan pada tahun 1940 sampai sekarang, Waduk Malahayu direncanakan  dapat menampung air 69 juta m³ dengan luas muka air 9,25 km², tujuan di bangunnya waduk malahayu ini untuk menyuplai areal irigasi sebesar 12,674 Ha dengan rincian DI Kabuyutan 4.166 Ha, DI Jengkelok 6.173 Ha, DI Babakan 2.335 Ha. Kondisi persediaan air di Waduk Malahayu terus menyusut yang diduga akibat adanya sedimen yang cukup tinggi.Untuk meningkatkan kinerja  Waduk Malahayu, diperlukan data pendukung berupa: system dan kinerja operasional waduk, data hidrologi, prosedur dan pembuatan pola pengoperasian waduk, dan data irigasi.Berdasarkan hasil analisis menunjukan bahwa pengoperasian Waduk Malahayu kurang optimal karena berdasarkan hasil analisis simulasi operasi waduk menunjukan bahwa volume air Waduk Malahayu dibawah volume normal. Minimum Operating Level (MOL). Berdasarkan catatan Balai Besar Wilayah Sungai (BBWS) Cimanuk-Cisanggarung, Sejak Waduk Malahayu dibangun pada jaman Pemerintahan Kolonial Belanda sampai sekarang, kondisi persediaan air di Waduk Malahayu terus menyusut. Kata Kunci     : Simulasi, Optimasi, Operasi, dan Waduk. ABSTRACTMalahayu reservoir is one of the artificial reservoirs that located in the watershed Kabuyutan upstream. Since Malahayu reservoir operated in 1940 until now, Malahayu reservoir is planned can collect water 69 million  m³ with 9,25 km² area of water surface. The purpose of built Malahayu reservoir is to supply irrigation area of 12.674 Ha with detail of Kabuyutan irrigation area 4.166 Ha, Jengkelok 6.173 Ha, and Babakan 2335 Ha. The condition of water supply in Malahayu reservoir continues to shrink. The depreciation was allegedly due to the quite high sediment.In the case to be achieved against Malahayu reservoir, it was required the data as support such as: reservoir systems and operational performance, hydrological data collection, procedure and pattern making operation of reservoir, irrigation performance data collection and preparation of reservoir operation pattern.Based on the results of the analysis showed that the operation of  Malahayu  reservoir was less optimal because the simulation analysis reservoir operation  shows that water volume of Malahayu  reservoir was under normal volume. Minimum Operating Level (MOL. Based on the notes of Balai Besar Wilayah Sungai (BBWS) Cimanuk-Cisanggarung, since Malahayu Reservoir was built in the Dutch Colonial era to the present, the condition of water supply in the Malahayu reservoir continues to shrink.  Keywords         : Simulation, Optimization, Operations, and Reservoir.
