Abstract

The application of the Normalized Difference Vegetation Index (NDVI) on multispectral satellite imagery has been extensively used to assess the quantitative and qualitative aspects of mangrove vegetation. However, the use of Sentinel-2 imagery for this purpose is still relatively new. This research aims to monitor the distribution and density of mangrove vegetation in West Sulawesi by implementing NDVI transformation on Sentinel-2 imagery. The mangrove forest in Mamuju Regency, located in West Sulawesi, is one of the rich areas of mangrove forests on the island of Sulawesi, Indonesia. However, this region also exhibits disturbances in the mangrove ecosystem, resulting in limited monitoring efforts. By utilizing NDVI transformation, we identified the distribution and density of mangrove vegetation using Sentinel-2 imagery. The accuracy of image classification was evaluated using the confusion matrix method, and further analysis was conducted using linear regression to test the relationship between NDVI and mangrove density values obtained from field surveys. The results indicate that the total area of the mangrove forest reaches 1,798 hectares distributed along the coastal areas in the districts of Sampaga, Papalang, Kalukku, Mamuju, Simboro, Tapalang Barat, and Tapalang. Nearly 60% of this area has high mangrove density, while approximately 7% to 9% falls into the low and lowest density categories. NDVI values range from 0.06 to 0.81, with the highest value found in the Mamuju District and the lowest in the Papalang District. The correlation between NDVI and mangrove density shows a strong positive relationship (R=0.78). Therefore, Sentinel-2 imagery demonstrates high accuracy and potential for the development of predictive models for mangrove vegetation density. These findings have significant implications for the development of conservation policies and environmental management, as well as raising public awareness of the importance of preserving mangrove forests.

Abstract

Bencana banjir terjadi setiap tahun di Kecamatan Tanah Grogot, besarnya kerugian dan kerusakan yang dapat ditimbulkan maka penelitian ini bertujuan untuk mengetahui tingkat kerawanan banjir dan agihan daerah rawan banjir. Menggunakan metode analisis  spasial dengan overlay (peta topografi, peta penggunaan lahan, peta buffer sungai, peta lereng, peta  tanah, dan peta curah hujan), dan skoring. Hasil penelitian menunjukkan bahwa terdapat tiga kelas tingkat kerawanan banjir yaitu: tidak rawan banjir dengan luas 8811,59 Ha (24,42%), rawan banjir dengan luas 17378,98 Ha (48,16%), dan sangat rawan banjir dengan luas 9898,98 Ha (27,43%). Agihan daerah rawan banjir terletak di seluruh desa dan kelurahan dengan luas yang berbeda-beda, hampir keseluruhan wilayah dari Kelurahan Tanah Grogot, Desa Sungai Tuak dan Desa Senaken masuk dalam kelas  sangat rawan banjir, dan lebih dari setengah wilayah Desa Muara Pasir masuk dalam kelas sangat rawan banjir. Sedangkan untuk desa lainnya kelas sangat rawan banjir tersebar di beberapa titik dengan luasan yang kecil. Daerah yang tidak rawan banjir yaitu Desa Pulau Rantau dan Desa Rantau Panjang.

Abstract

Urbanization and rapid development in Makassar City have led to habitat fragmentation, affecting the sustainability of avian species in the area. This study aims to understand the carrying capacity of private green spaces (RTH) in preserving avian species in Makassar City. The results indicate a moderate diversity index, with 19 bird species identified. The Eurasian Tree Sparrow and Sooty-headed Bulbul are the most common species, but species distribution is even, suggesting that no species significantly dominates. These findings indicate that despite urbanization pressures, private RTH remains an important habitat for birds. Endemic species like the Makassar White-eye, as well as threatened species such as the Java Sparrow and the Asian Koel, which are classified as Endangered and Vulnerable by the IUCN Red List, were found in the area. Additionally, these RTHs support protected species like the Great Egret, which plays a vital role in maintaining the balance of local aquatic ecosystems. The study concludes that private RTHs in southern Makassar City play a crucial role in bird conservation and the balance of urban ecosystems. Wise protection and management of these areas are essential to support biodiversity amidst intensive urbanization. These findings can serve as a basis for better environmental policy development, benefiting not only bird species but also the overall health of urban ecosystems.
