Abstract

A puddle is a condition where the water stops flowing in a certain area that is not a water body. In theory, a boezem building in Blimbing Village can help control the inundation and soak it into the ground. However, until now, there are still cases of inundation in Blimbing District. Therefore, this study aims to determine the existing conditions of drainage and boezem, and plan alternative buildings that can help the performance of boezem as a conservation-based inundation controller. From the analysis, the existing drainage and boezem cannot fully accommodate the design discharge. The inability of the existing boezem to accommodate all the total design flows leaves an inundation of 2,076 m3/s with a 2-year return period and 2,551 m3/s with a 5-year return period. Two conservation-based alternatives are offered to control the inundation. Based on technical and economic analysis, a 595-unit infiltration well was chosen in the boezem catchment area with total flood reduction of 22% and Rp's total fund. 3,276,869,973.16.Genangan merupakan kondisi dimana air berhenti mengalir pada suatu area tertentu yang bukan merupakan badan air. Adanyan bangunan boezem di Kelurahan Blimbing secara teori dapat membantu mengendalikan genangan dan meresapkannya ke dalam tanah, namun sampai saat ini masih terjadi kasus-kasus genangan di Kecamatan Blimbing. Maka dari itu penelitian ini bertujuan untuk  mengetahui kondisi eksisting drainase dan boezem serta merencanakan alternatif bangunan yang dapat membantu kinerja boezem sebagai pengendali genangan berbasis konservasi. Dari hasil analisa, drainase dan boezem eksisting tidak dapat sepenuhnya menampung debit rancangan. Ketidakmampuan boezem eksisting dalam menampung seluruh debit rancangan total menyisakan genangan sebesar 2.076 m3/dt dengan kala ulang 2 tahun dan 2.551 m3/dt dengan kala ulang 5 tahun. Untuk mengendalikan genangan tersebut ditawarkan dua alternatif berbasis konservasi. Berdasarkan analisa teknis dan ekonimis dipilihlah pembangunan 595-unit sumur resapan pada catchment area boezem yang dapat mereduksi 22% debit genangan dengan total dana sebesar Rp. 3,276,869,973.16.

Abstract

Background: Subsidized housing for Low-Income Communities (LIC) in Indonesia continues to encounter significant quality challenges, particularly in disaster-prone regions. These challenges are primarily associated with the limited enforcement of technical standards, insufficient infrastructure provision, and inadequate policy support, which collectively undermine the resilience and habitability of such housing.Aims and Methods: This study analyzes the quality and resilience of subsidized housing for LIC in Padang City, which are in disaster-prone zones. Using questionnaire survey methods and factor analysis, this study identified technical and non-technical variables that affect the feasibility of housing. The KMO-Bartlett test, validity, and reliability ensured the instrument's feasibility, resulting in 18 valid variables grouped into four main factors: the quality of infrastructure, facilities, and public utilities (IFP), housing development policies and support, technical quality and housing standards, and residential accessibility.Result: The study results show that basic infrastructure, regulatory support, implementation of technical standards, and strategic location have a significant role in the quality of subsidized housing. These findings confirm the importance of synergy between technical and policy aspects in improving the quality and resilience of subsidized housing, especially in disaster-risk areas.
