STUDI EVALUASI SALURAN DRAINASE PADA DESA PUCUNG KIDUL KECAMATAN BOYOLANGU KABUPATEN TULUNGAGUNG

Abstract

Pucung Kidul Village, is a village located in Boyolangu District, Tulungagung Regency. Based on field observations, it is known that one of the factors causing flooding and inundation is due to inadequate drainage facilities. In this research evaluation study of drainage channels, it discusses the solutions used to overcome the problems of flooding and inundation in Pucung Kidul Village by applying the conceptecodrainage namely the use of infiltration wells and planning improvements to the new channel dimensions. By calculating using the Log Person type III method with a return period of 10 years, the rainfall and design discharge are 127.41161 mm. The results of the evaluation of the drainage channels revealed that 8 out of 11 existing channels were unable to accommodate the design discharge and after the plan to improve the new channel dimensions, the results obtained were 3 channels with new dimensions that could accommodate the design discharge. On the application of the conceptecodrainage planned on 5 channels which could not accommodate the design discharge after the new channel dimension plan was carried out, the results of the planning infiltration wells were obtained with an efficiency percentage of 66%, 79%, 35%, 38%, and 76% respectively.
