Abstract

Infiltration wells are a form of hydrological infrastructure used to manage rainwater. Infiltration wells are usually built as part of a rainwater management system to soak rainwater into the ground and reduce surface waterlogging as well as slow down surface runoff and allow rainwater to seep into the ground to renew aquifers or prevent waterlogging. Maintaining groundwater levels is an important step in sustainable water resource management. The aim of this research is to plan effective infiltration wells to replace rainwater catchment areas lost due to building construction. The planning of this infiltration well uses the Sunjoto  method. From the research results, it was found that an effective infiltration well design was calculated using the Sunjoto  method. With the data, each roof area of ​​the house has an optimum number of infiltration wells with a planned infiltration well diameter of 1 m with a depth of 2.5 m with an effective depth according to the calculations is as follows: 60 m2 number of 1 unit of absorption well with an optimum depth of 2.82 m, 80 m2 number of 2 units of absorption well with an optimum depth of 3.76 m, 100 m2 number of 2 units of absorption well with an optimum depth of 4.7 m, 120 m2 number of 2 units of infiltration wells with an optimum depth of 5.64 m, 140 m2 number of 3 units of absorption wells with an optimum depth of 6.58 m, 160 m2 number of 3 units of absorption wells with an optimum depth of 7.52 m, 180 m2 number of 3 units of absorption wells with an optimum depth of 8.46 m, 200 m2 total of 4 units of infiltration wells with  an  optimum depth  of 9.4 m.

Abstract

Kapas District is located in Bojonegoro Regency with an area of ​​2,927 ha of rice fields and 2,805 ha of irrigation land. The obstacle faced by farmers is the uneven availability of irrigation water. The irrigation area in Wedi Village is still simple irrigation by pumping river water next to it. This research aims to plan the irrigation network in Wedi, by calculating irrigation water needs and planning the dimensions of the irrigation channels. The algebraic method is used to calculate rainfall and calculate water needs using the Net Field Requirements (NFR) system. Water requirements at the beginning of planting in November I obtained a maximum value of 1.79 lt/s/ha, the alternative for beginning of planting in December I obtained a maximum value of 1.90 lt/s/ha, and the alternative for beginning of planting in December II obtained a value of 1.88 lt/s/ha. Results of overall water balance analysis for each month in 1 year with 3 alternative plantings with surplus results. The channel dimensions obtained are SP 1 = 1.4 m x 1 m, SP 2 = 1.4 m x 1 m, SP 3 = 1.2 m x 1 m, SP 4 = 1.2 m x 1 m, and for secondary channels the results are SS 1 = 0.6 m x 1 m , SS 2 = 0.8 m x 1 m, SS 3 = 0.6 m x 1 m , SS 4 = 0.6 m x 1 m = , SS 5 = 0.6 m x 1 m.  Keyword: Network Planning, Plant_water_requirements, NFR, channel dimensions.
