Abstract

Cipaleubuh Irrigation gets water from the Cipaleubuh River for the needs of rice fields and plantations in Pameungpeuk. To determine water availability and effectiveness of irrigation channels. This research was conducted to determine the Cipaleubuh Bend River Discharge and Irrigation Discharge by taking into account current conditions. The research location is Cipaleubuh Dam to Cipaleubuh Irrigation with an area of ​​1016 ha. The largest river discharge is 5.66 m3/second using the FJ Mock Method, evapotranspiration calculations using 10 years of climatology data and 10 years of rainfall data using the Penman Monteith Method. The Cipalebuh irrigation area with an area of ​​1,016 hectares requires water withdrawals, water availability is still sufficient from January to June, and scarce from July to October, but water availability is low at the end of the year. reduced capacity. Enough for November and December. Based on the analysis results, the maximum river discharge was 5.66 m3/s in March. A water intake of 1.65 l/sec/ha at the key requires a required water volume of 1016x1.65 = 1676.4 l/sec. Cipaleubuh land use is divided into river areas, plantation areas, gardens, irrigated rice fields, bushes and agricultural land. Fertile land contributes 30.880% compared to 2.017% for river water. However, water needs can be met with DI. Effective Cipaleubuh.

Abstract

The Leuwikeris Dam is a dam built in two districts, namely Ciamis Regency and Tasikmalaya Regency. One of the structures of the dam is a stilling pond. Stilling ponds are built to reduce the energy contained in the flow by utilizing hydraulic jumps from a high-speed flow. The type of stilling pond at the Leuwikeris Dam is type USBR II which has a Froude number value of more than 4.5 and a discharge of more than 60m³/second. The research carried out this time calculated the amount of energy loss in the stilling pond of the Leuwikeris Dam with the USBR II stilling pond type. In finding the value of energy loss, the discharge of the Leuwikeris Dam is needed using modeling. Discharge modeling uses the NRECA method by calibrating with existing discharge, namely the discharge in Cirahong. Discharge modeling is also used with normal distribution method calculations, log normal, gumbel and log pearson type III. The results of these calculations are an NSE value of 0.756 in modeling discharge using the NRECA method and calibrated with the Cirahong discharge for 5 years and the amount of energy lost in the stilling pond of 4.78 meters.

Abstract

Clean water is the main source for society. However, not all areas have sufficient availability of clean water, for example Pangkalan Village and Pasir Mukti Village which are located in Tenjowaringin Village. In this research, planning for the availability of clean water was carried out for the people of Pangkalan village and Pasir Mukti village. The spring used in the planning was the Cipeuti spring, the water source of which had not been utilized at all. The method used to determine the amount of discharge is the volumethic method by collecting spring water, then the water is raised to the distribution reservoir using a pump, then the water is distributed using a gravity system. However, the method that will later be used for distribution of clean water is planned using the help of Epanet 2.2 software. The results of the analysis of water needs until the 2033 plan year showed that the population was 474 people using the geometric method, for a water discharge of 13,140 lt/day (0.16 lt/sec) with Cipeuti water availability until 2033, namely 0.17 lt/sec. The results of the calculations show that the availability of clean water in Cipeuti can meet the water needs of the people of Pangkalan village and Pasir Mukti village. For the dimensions of the reservoir used, namely 2.5 m x 2.5 m x 3 m and the dimensions of the planned reservoir are 2.5 m x 2.5 m x 3.5 m, the type of pipe used is HDPE pipe, where the value of the pipe coefficient uses Hazen Williams values ​​which will later be applied in the Epanet 2.2 application for pipe distribution.

Abstract

The availability of water at Gunungcupu Dam is very much needed to support various community activities in the service area. One of the causes of the reduced supply of clean water is damage to pipes due to natural disasters, such as what happened in 2022, there was a flash flood that overflowed the Citanduy River located in the Gunungcupu Bend area and caused the main raw water transmission pipe belonging to PDAM Tirta Galuh Ciamis to reach the Gunungcupu Intake. cut off for 100 meters, as a result the water supply in the Gunugcupu Dam service area was disrupted. So this research was carried out to determine the availability of raw water, find out the projected need for clean water in 2042, and find out the planned flood discharge at Gunungcupu Dam. The method used is a quantitative approach. To determine the availability of raw water, you need to process actual discharge data using the Weibull equation, calculate population projections using arithmetic and geometric methods, calculate clean water requirements for domestic needs in 2042, and process rainfall data to analyze the planned maximum discharge using the Unit Hydrograph method. Nakayasu Synthetic and Gama I Synthetic Unit Hydrograph. The calculation results show that water availability at the Gunungcupu Dam is 730 liters/second. The need for clean water in 2042 for the three sub-districts is 302.66 liters/second. Based on these results, the water supply from Gunungcupu Dam can meet the clean water needs for Ciamis, Baregbeg, and Cijeungjing Districts in 2042. Then the flood discharge planned by the Nakayasu HSS method for Gumbel probability at Q100 is 930,484 m3/second and for Log Normal probability at Q100 amounting to 786,302 m3/second, while the planned flood discharge for the HSS Gama I method for Gumbel probability in Q100 is 833,381 m3/second and for Log Normal probability in Q100 is 707,002 m3/second. Based on these results, it can be concluded that the largest maximum discharge is the HSS Nakayasu method for Gumbel probability, so the HSS Nakayasu method is good for planning the safety of water structures against flooding.

Abstract

Clean water plays a very important role in everyday life. However, the dry season causes a water crisis in several areas of Garut Regency, one of which is Cibunar Village, Cibatu District. The aim of this research is to plan drinking water discharge needs, storage tank capacity and water distribution planning by maximizing the potential of drilled well water as a source of raw water. There is a need for distribution engineering with PVC pipe networks and combined drainage systems. In planning this network, population projections use the geometric method for the 2023-2042 plan year with a population at the end of the plan year of 11,191 people, the total water requirement per person is 60 liters/person/day. The total domestic water requirement for one village is 671,460 liters/person/day or 7.77 liters/second at the end of the 2042 projected plan year. The complete data was then analyzed using the EPANET 2.2 application, the results of the analysis obtained the average pressure 25.23 m, average head loss 0.56 km/m and average flow speed 0.18 m/s and from the results of this analysis the ideal diameter of the distribution pipe is 100-200 mm. Meanwhile, the results of running with the peak hour scenario obtained a flow of 879 liters/hour. In planning the pump specifications required a total head of 159.34 m and a power of 45.41 Kw with pump type CR 120-5-1. Cibunar Village distribution network planning at the end of the planning year can meet community needs during the planning period.
