Abstract

Banjir merupakan salah satu bencana alam yang sering terjadi di Indonesia, termasuk di Kecamatan Pasar Kemis, Kabupaten Tangerang. Faktor utama penyebab banjir di wilayah ini adalah tingginya curah hujan, buruknya sistem drainase, serta meluapnya sungai yang melewati daerah tersebut, seperti Sungai Cirarab dan Saluran Pembuang Gelam. Untuk mengatasi permasalahan ini, diperlukan suatu sistem pengelolaan banjir yang efektif, salah satunya melalui pembangunan kolam retensi. Penelitian ini bertujuan untuk menganalisis kebutuhan volume kolam retensi sebagai sistem pengelolaan banjir di Kecamatan Pasar Kemis serta menentukan efektivitasnya dalam mereduksi debit banjir. Metode yang digunakan dalam penelitian ini adalah pendekatan kombinasi kuantitatif dan kualitatif. Analisis hidrologi dilakukan dengan menggunakan perangkat lunak Hydrognomon untuk memperoleh debit banjir rencana dengan metode HSS Snyder-Alexeyev. Selanjutnya, pemodelan hidrolika dilakukan dengan perangkat lunak HEC-RAS untuk menganalisis volume genangan serta efektivitas kolam retensi dalam mengurangi banjir. Hasil analisis menunjukkan bahwa debit banjir rencana di Saluran Pembuang Gelam untuk periode ulang 2 hingga 100 tahun berkisar antara 5,56 m³/det hingga 17,40 m³/det. Alternatif terbaik untuk volume kolam retensi yang dirancang adalah Alternatif 6, yaitu kolam dengan kapasitas 30.000 m³ serta dilengkapi dengan tiga pompa. Alternatif ini mampu mengurangi luas genangan dari 1.795,7 m² menjadi 831,8 m². Hasil pemodelan dengan HEC-RAS menunjukkan bahwa keberadaan kolam retensi dapat mengurangi volume banjir hingga 53,68%.

Abstract

The success of a construction project is not only measured by the achievement of technical aspects such as cost, quality, and time, but is also greatly influenced by stakeholder engagement. This is increasingly relevant for irrigation network rehabilitation projects that have a strategic role in supporting food security. This study aims to analyze the influence of stakeholder involvement consisting of project owners (owner/promoters), planning consultants (designer/defender), regulators and regional authorities (latent), as well as the end-user community or the Water User Farmers Association (P3A/apathetic) on the success of the irrigation network rehabilitation project of D.I. Buloila Kanan, Gorontalo. The research method uses a quantitative approach by collecting primary data through questionnaires to respondents who are directly involved in the project, both from elements of the government, consultants, contractors, and the community. Data were analyzed using descriptive methods and inferential tests to determine the partial and simultaneous influence of stakeholder involvement on the success of the project. The results show that the involvement of each stakeholder has a significant effect on the success of the project. The project owner plays a role in the provision of budgets, operating policies, and maintenance (O&M). The planning consultant determines the technical quality of the design according to local hydrological and socio-economic conditions. Regulators and regional authorities facilitate the administrative process and synchronization of spatial planning. Meanwhile, P3A contributes to the sustainability of irrigation functions through active participation in operations and maintenance. Simultaneously, the involvement of all stakeholders strengthens the success of the project, both in terms of physical output and long-term benefits. The conclusion of this study confirms that synergy between stakeholders is the main determinant of the success of irrigation network rehabilitation projects.

Abstract

Construction projects in DIY have high complexity because they are located in disaster-prone areas such as earthquakes, floods, and landslides, so they require structured risk management. This research aims to analyze the influence of cost, quality, time, and accident risk identification on disaster risk management of construction projects. The research employed a quantitative approach by distributing questionnaires to 30 respondents consist of contractors, consultants, and project supervisors. Data were analyzed using statistical test multiple linear regression to examine the influence of each aspect on disaster risk management. The findings indicate that cost risk identification has a significant effect on risk management effectiveness, particularly in preventing budget overruns caused by external conditions such as material inflation and supply uncertainty. The quality aspect contributes substantially to improving construction resilience against disasters, in line with the application of quality standards based on SNI and ISO. The time aspect shows a clear influence on successful risk mitigation, as project delays increase vulnerability to disaster impacts. Meanwhile, accident risk identification is strongly related to the contractors’ readiness in implementing occupational health and safety (OHS) procedures to reduce potential human and material losses. Overall, this study emphasizes the importance of integrating risk identification into the construction project management system in the Special Region of Yogyakarta Province. The findings provide practical implications for contractors, local governments, and other stakeholders in developing adaptive, measurable, and responsive risk management strategies in disaster-prone regions
