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.

Abstract

The expansion of urban functions fosters the creation of new activity centers beyond existing built-up areas, thereby transforming rural landscapes into semi-urban zones. Driven by rapid globalization, technological advancements, and population growth within urban areas, peri-urbanization—as a manifestation of urban expansion—has become an inevitable phenomenon. This phenomenon is evident in the Kawasan Perkotaan Yogyakarta (KPY), which administratively encompasses three jurisdictions: Yogyakarta City as the urban core, along with portions of Sleman and Bantul Regencies. Currently, the trajectory of urban sprawl is shifting southward toward Bantul Regency. This study aims to delineate the peri-urban zones within the Kawasan Perkotaan Yogyakarta (KPY). This research employs a quantitative approach utilizing Geographic Information System (GIS)-based spatial analysis. Regional clustering was performed using the k-means algorithm based on four primary variables: percentage of built-up land, net population density, percentage of non-agricultural households, and availability of public facilities. The results indicate that peri-urban areas in the KPY are no longer confined by administrative boundaries but have significantly expanded southward into Bantul Regency. The study classifies the region into four distinct zones: (1) urban core, (2) urban fringe, (3) peri-urban, and (4) rural. These findings indicate a substantial transformation of agricultural land into non-agricultural use within the peri-urban zone. Consequently, this study recommends the integration of cross-regional spatial planning policies within the KPY to control land conversion and ensure sustainable development in these transitional areas.

Abstract

Rukun tetangga (RT) 035 Kelurahan Karang Joang merupakan kawasan pemukiman yang memiliki potensi untuk berkembang karena berada di lokasi strategis. Fasilitas seperti peta lingkungan yang memuat informasi spasial berupa rumah warga, fasilitas umum, akses jalan, maupun potensi dan resiko lingkungan tidak terdokumentasi dengan baik. Ketiadaan data spasial tersebut dapat menghambat proses berkembangnya RT 035. Pemetaan partisipatif menjadi salah satu solusi dalam mewujudkan kawasan strategis. Pemetaan partisipatif tidak hanya menghasilkan produk peta, tetapi menjadi sarana edukasi, pemberdayaan, dan penguatan ikatan sosial warga dalam membangun kesadaran kolektif terhadap ruang hidup mereka. Pemetaan partisipatif dalam pengabdian ini memiliki 3 tahap. Tahap pertama sosialisasi program pemetaan partisipatif, tahap kedua pelatihan penambahan titik lokasi melalui Google Maps, tahap ketiga yaitu bimbingan teknis kepada warga yang memiliki kendala terkait penambahan titik lokasi. Berdasarkan hasil survei yang diperoleh dari data kuesioner, 92% peserta menyatakan pelatihan mudah dipahami, 88% peserta merasa pelatihan bermanfaat untuk kegiatan sehari-hari, 84% menyatakan siap membantu memperbarui data lokasi, dan 8% peserta masih merasa kesulitan akibat keterbatasan kemampuan perangkat. Berdasarkan hasil survei tersebut, masyarakat antusias dan merasa terbantu dengan adanya sosialisasi pemetaan partisipatif dan penambahan fasilitas peta lingkungan RT 035 Karang Joang.
