Evaluasi Kelayakan Kapasitas Drainase Pada Jalan Perumahan Arcawinangun, Kecamatan Purwokerto Timur, Kabupaten Banyumas

Introduction

Evaluasi kelayakan kapasitas drainase pada jalan perumahan arcawinangun, kecamatan purwokerto timur, kabupaten banyumas. Studi ini mengevaluasi kapasitas drainase Jalan Perumahan Arcawinangun, Purwokerto Timur, Banyumas. Meskipun ada sedimentasi penyebab genangan, saluran drainase terbukti masih mampu menampung air.

Abstract

Drainage on Arcawinangun Housing Road, East Purwokerto Subdistrict, Banyumas Regency often experiences flooding caused by sedimentation. This study aims to determine the drainage capacity on Arcawinangun Housing Road, East Purwokerto Subdistrict, Banyumas Regency, whether it is still capable of accommodating and draining the total flow of rainwater runoff and household waste. The results of the study and calculations show that the total flow (Qtotal) ranges from 0.00361 m³/sec to 0.01086 m³/sec and the existing drainage channel flow after sedimentation (Qsed) ranges from 0.065 m³/sec to 2.488 m³/sec. The conclusion of this study is that the discharge of existing drainage channels after sedimentation is greater than the total flow discharge (Qsed > Qtotal), meaning that each existing drainage channel after sedimentation is still capable of accommodating and draining the total flow discharge of both rainwater runoff and household waste. .

Review

This paper addresses a highly relevant and common urban problem: flooding caused by inadequate drainage, specifically highlighting the role of sedimentation in a residential area. The stated objective to quantitatively assess the capacity of the existing drainage system in Arcawinangun Housing Road to accommodate rainwater runoff and household waste flow is clear and holds practical significance for local infrastructure management and flood mitigation efforts. The focus on a specific location indicates a case study approach, which can provide valuable insights for similar contexts. The abstract presents key quantitative findings, indicating ranges for the total flow (Qtotal) and the existing drainage channel flow after sedimentation (Qsed). The calculated Qtotal ranges from 0.00361 m³/sec to 0.01086 m³/sec, while Qsed ranges from 0.065 m³/sec to 2.488 m³/sec. Based on these figures, the study concludes that Qsed is greater than Qtotal, asserting that the existing drainage channels, even after sedimentation, are still capable of accommodating and draining the total flow. This provides a direct answer to the study's objective using numerical evidence. However, a significant ambiguity arises from the abstract's conclusion when juxtaposed with its initial problem statement. If the drainage channels, even after sedimentation, are indeed capable of handling the total flow (Qsed > Qtotal), it directly contradicts the initial premise that the area "often experiences flooding caused by sedimentation." This discrepancy requires thorough explanation within the paper. As a reviewer, I would question whether the calculated "Qsed" truly represents the *functional capacity* of the channels during flood events, or if other critical factors, such as specific blockage points, inadequate inlet capacity, maintenance issues, or the frequency and intensity of peak rainfall events, are overlooked. The paper would benefit from clarifying this apparent contradiction to provide actionable insights into the true causes of flooding and potential solutions.
