Identification of Damage Type of Side Ditch Drainage at BenuaMelayuLaut Village, Pontianak City, West Borneo, Indonesia

Abstract

One of the causes of the damage to the side ditch is the absence of a maintenance process, the absence of supporting water management for settlements on the banks of the Kapuas River, especially in the BenuaMelayuLaut (BML) Village, Pontianak, Indonesia. This area often floods during the rainy season, therefore this research needs to be done. The purpose of this study is to identify damage to the existing drainage system, how to handle it and actions to overcome flooding problems in the area caused by damage to the drainage side ditch management system. The qualitative method of determining the types of severe, moderate and light damage is then identified and determined by the type of handling in the form of routine maintenance, periodic maintenance and rehabilitation in the form of construction of new drainage. Based on the analysis of the type of damage, it was found that the damage was minor by 20.00%, it was necessary to carry out routine maintenance; moderately damaged 14.29%, need periodic maintenance, no drainage channel 34.29%, so it must build a new channel (rehabilitation); and 31.43% natural channels, need regular maintenance.
