Abstract

Tidal flooding often occurs in coastal areas and this is sometimes very difficult to predict because it can occur suddenly this happens because sea water is higher than the land surface. This research aims at 1) vulnerability to tidal flooding due to sea level rise,, 2) disaster mitigation of community preparedness. This type of research is quantitative. Data were analyzed using the overlay method and mitigation using the PLS (Partial Least Square) approach, and by taking random sampling of the population. This research results in 1) tides have a formzahl value of 0.31 with a mixed type leaning to double daily occurring twice the tide and twice the ebb with almost the same height, in tidal affected areas have 2 classes, namely vulnerable and not vulnerable areas that are quite vulnerable have an area of 1009 Ha. The distribution of areas classified as quite vulnerable is in areas close to the coast. Areas that are not vulnerable have an area of 11,173 with areas that are not close to the coast. 2) on policies, emergency response plans, disaster warning systems, resource mobility is able to explain the preparedness variable by 60.9%. Based on the results of these calculations it can be concluded that this research model is included in the moderate or moderate category. Because if > 0.50 indicates a moderate model.

Abstract

Seagrass (Lamun) is a flowering plant (Angiospermae) that thrives in shallow marine environments. Seagrass meadows play a crucial role in aquatic ecosystems, and the degradation or loss of seagrass can impact the balance of these ecosystems. The use of remote sensing technology in mapping the distribution of seagrass beds can support monitoring efforts and contribute to the conservation and protection of marine ecosystems. This research aims to map and measure the extent of seagrass beds in Nirwana Beach, Padang City, in the year 2022. The method employed involves using Sentinel-2A imagery from 2022 and the Object-Based Image Analysis (OBIA) approach for seagrass detection. The Sentinel-2A imagery is processed using ArcGIS and eCognition software, including atmospheric correction, data clipping, composite image creation, segmentation, image classification, and accuracy assessment. The results of processing the Sentinel-2A data in 2022 for Nirwana Beach, Padang City, indicate that seagrass beds are distributed along the Nirwana Beach area, particularly in the eastern and southern regions. The detected seagrass bed covers an approximate area of 25.06 hectares. The use of Sentinel-2A imagery with the OBIA method has proven to be effective in detecting the distribution of seagrass beds in Nirwana Beach, Padang City.

Abstract

Object-based image analysis (OBIA) is an image classification that considers not only the spectral aspects of objects, but also their spatial aspects. This classification is guided by objects that have distribution patterns from object samples which are used as references for their accuracy. However, this object-based classification process must be taken into account when looking at color and calculating it so that there is no error in classification. In this research, the OBIA method was used to identify changes in land use in the Bungus Teluk Kabung District in 2012, 2017 and 2022. By using the OBIA method, identification results were obtained in areas where land use changes occurred between 2012 and 2017, which were identified as having changed from open land to built-up land. with an area of 355.84ha, plantations 22.62ha and rice fields 20.97ha. From 2017 to 2022, it was identified that there was a change in land use from dry land forests to 6.30ha of built-up land. The change in open land to built-up land was 7.47ha. Plantations experienced changes to 6.21ha of built-up land and 9.27ha of rice fields. Meanwhile, bushes/shrubs experienced changes in plantations of 2.47ha.
