UJI COBA PENGGUNAAN ALAT PORI ANTI BANJIR SELAMA 5 JAM UNTUK MENENTUKAN JUMLAH PEMASANGAN PADA BERBAGAI LUASAN RUMAH

Abstract

Not all of rainwater can precipitate because determine of coefficient run off C, soil, and type of building. Pori Anti Banjir (the number of intellectual property rights is 079102) has been designed to improve precipitation of run off so it’s can remove of flood. All types of physical development can eliminate catchment areas, so we need to install pori anti banjir. To determine how much to install pori anti banjir on every house and new building, so we need the trial precipitation run off used pori anti banjir. The time of running were 5 hours or 50 % I. The various of running were can see at table 1. If pori anti banjir were saturated or full, the injection were stopped and to be continued next day with flow injection were 50% q from starting flow. If 50% of starting flow can’t aplicated 5 hours, the flow passed down 33 % to 25 %. The additional at the aplicated is 2;3; or 4 from starting calculation. The benefits of this experiment to calculate the needs to install pori anti banjir of development property (house or new building). The equipment of pori anti banjir were install at cemented land 7 m² circle area with 3 m diameter. Maximal flow at the 5 hour injection were 2 litre/minute. The result of experiment were  every types of houses need installed pori anti banjir each 36 is 3; 45 is 4; 60 is 5; and 75 is 6.
