Abstract

The relocation of the capital city (IKN) to East Kalimantan, as regulated by Law Number 3 of 2022, will drive massive regional development. However, the province of East Kalimantan, which is prone to flooding, requires a special approach such as implementing the Sponge City concept to minimize flood risks and support the sustainable development of IKN. This research aims to provide recommendations for effectively implementing Sponge City infrastructure to address flood issues in IKN through a comparative study of the application of the Sponge City concept in China. Secondary data is used in this research, covering variables such as topography, climate, area size, rainfall, annual flood frequency, and the objectives of the capital city. The methods used include a comparative study with cluster analysis to compare city characteristics, performance analysis to assess effectiveness, and descriptive analysis to provide recommendations for the implementation of Sponge City in IKN. The results indicate that Nanjing and Haikou in China serve as benchmarks, with retention ponds, green roofs, and wetlands being effective infrastructures for flood management. Wetlands are considered the most economical and effective infrastructure to implement in IKN due to their lower maintenance costs compared to retention ponds and green roofs.

Abstract

Pemindahan Ibu Kota Negara (IKN) ke Kalimantan Timur, sebagaimana diatur oleh Undang-Undang Nomor 3 tahun 2022, akan mendorong pembangunan masif di wilayah tersebut. Namun, Provinsi Kalimantan Timur yang rawan bencana banjir memerlukan pendekatan khusus seperti penerapan konsep Kota Spons untuk meminimalisir risiko banjir dan mendukung keberlanjutan pembangunan IKN. Penelitian ini bertujuan untuk memberikan rekomendasi penerapan infrastruktur Kota Spons yang efektif dalam mengatasi permasalahan banjir di IKN melalui studi perbandingan terhadap penerapan konsep Kota Spons di China. Data sekunder digunakan dalam penelitian ini, mencakup variabel topografi, iklim, luasan wilayah, curah hujan, frekuensi banjir per tahun, dan tujuan ibukota negara. Metode yang digunakan adalah studi komparatif dengan analisis klaster untuk komparasi karakteristik kota, analisis performa untuk menilai efektivitas, dan analisis deskriptif untuk memberikan rekomendasi penerapan Kota Spons di IKN. Hasil penelitian menunjukkan bahwa Kota Nanjing dan Kota Haikou di China menjadi acuan perbandingan, dengan infrastruktur kolam retensi, atap hijau, dan lahan basah yang efektif mengatasi banjir. Infrastruktur lahan basah dinilai paling ekonomis dan efektif untuk diterapkan di IKN karena biaya perawatannya lebih rendah dibanding kolam retensi dan atap hijau.

Abstract

Mangrove ecosystems are a crucial component of coastal areas, serving both strategic ecological and economic functions; however, their existence is vulnerable to human activities and the dynamics of coastal environments. The Balikpapan Barat subdistrict is one of the areas in Balikpapan City that features various types of activities, including settlements, industrial activities, and port activities, which have the potential to impact the condition of the mangrove forests. This study aims to analyse changes in the area and density of mangrove forests in 2019 and 2025 using the Normalised Difference Vegetation Index (NDVI) method based on Sentinel-2A satellite imagery. The research method comprises three stages: image pre-processing, NDVI value calculation, and classification of mangrove density into three classes: low, medium, and high. The analysis results indicate a decline in the distribution area of mangroves in West Balikpapan District, primarily due to anthropogenic activities such as infrastructure development, settlement expansion, and coastal industrial activities. However, some areas still exhibit moderate to high vegetation density, indicating the presence of natural regeneration processes and the role of conservation areas in maintaining mangrove ecosystems. This study confirms that the use of remote sensing imagery and the NDVI method is effective in supporting spatial and sustainable mangrove monitoring, and can serve as a basis for planning the management and conservation of mangrove ecosystems in coastal areas.Keywords: mangrove, NDVI, Sentinel-2, Area, Density, West Balikpapan.
