Analisis Kapasitas Saluran Drainase Pada Pembangunan Plengsengan Saluran Batu Kali (Brandgang Pucang Kertajaya – Manyar Dukuh)

Abstract

The drainage system serves as a crucial channel for redirecting excess water mass from areas such as residential, urban, and road environments. Its primary role is to prevent surface waterlogging, exemplified by the construction project of an irrigation channel along Jl.Raya Kertajaya - Surabaya. This initiative responds to frequent flooding issues in the region, acknowledging the serious repercussions floods pose in terms of material and non-material losses, as well as disruptions to daily life. The contemporary trend favors drainage as a preferred solution due to its benefits in mitigating intense rainfall-induced floods and managing swift water flow. The implemented manual excavation and placement of river stones (Plengsengan) aim to reinforce the channel against collapse or displacement caused by water pressure or external loads. The expansion project targets three points (A, B, C) with a planned duration of 120 days/4 calendar months. Commencing with the socialization phase, the fieldwork has progressed to manual excavation for channel restoration and the installation of river stones. This study focuses on observing the development of the Plengsengan stone channel (40/120) within the context of the practical fieldwork progress. The field practice is conducted under the guidance of CV.Sanjaya Persada, the implementing entity for the construction project along Jl.Raya Kertajaya – Surabaya.
