REPLANNING OF OPEN DRAINAGE ON THE NORTH SIDE OF RUNWAY 28 INSPECTION AT SYAMSUDIN NOOR AIRPORT, BANJARMASIN, SOUTH KALIMANTAN

Abstract

Syamsudin Noor Airport in Landasan Ulin District, Banjarbaru Regency, South
Kalimantan Province, is experiencing flooding problems in the drainage channel along the
northern side of runway 28 due to inadequate existing channel conditions. This problem
disrupts airport operations and triggers complaints from nearby residents.
To address this issue, an open drainage channel development plan is proposed to enhance
flight safety and minimize environmental impacts. The plan begins with the collection of rainfall
data to calculate the maximum rainfall intensity for the next 10 years using the Log Pearson III
method.
The analysis results show that the maximum rainfall intensity in the catchment area is
8.065 m³/s, with a design discharge of 3.9 m³/s. The planned open channel dimensions are 1.2
m wide and 1.4 m high, with an estimated budget of IDR 1,071,200,000
