Abstract

The distribution and abundance of fish are strongly influenced by several oceanographic parameters, one of which is chlorophyll-a. Chlorophyll-a is one of the oceanographic parameters that play an important role in primary productivity in the sea. The distribution of chlorophyll-a contained in phytoplankton can be used as a measure of fertility in water. With advances in geographic information systems or remote sensing, the distribution of chlorophyll-a can be used to estimate fish catchment areas. This study aims to look at the distribution of chlorophyll-a in Aceh waters both spatially and temporally to predict fishing locations. This study used satellite imagery combined with a Geographic Information System (GIS) to detect chlorophyll-as distribution. The results of satellite image processing show that the average monthly value of chlorophyll-a in Aceh waters ranges from 2.71 23.54 mg/m3, areas with high chlorophyll-a are generally located in the western waters of Aceh to the southwestern waters of Aceh, while areas with The lowest chlorophyll-a is generally in areas far from the coast (towards the open sea) with a range of 0.04 0.5 mg/m3 where the lowest average occurs in the east monsoon. However, in general, the potential locations for fishing grounds are more in the waters west of Aceh than in the waters north of Aceh, Aceh waters.Keywords:Chlorophyll-aSatellite imageFishing areaGeographic information SystemAceh Waters

Abstract

Mangrove has the most important role especially in the coastal area. The existence of mangrove habitats in BandaAceh which got decreasing and loss after tsunami disaster in 2004. The purpose of this study was to thedistribution of mangrove in Banda Aceh divided into five (5) sub districts including Jaya Baru, Kuta Alam, KutaRaja, Meuraxa, and Syiah Kuala. This study the mangrove changes after tsunami 2004, began from 2005, 2010,2015, and 2022. The main data used in this study are Landsat 5 and Sentinel 2A images. Methods of imageprocessing applied in this study are NDVI analysis and supervised classification-based image classification. Theresults are able to show the changes of mangrove area in Banda Aceh from 2004 to 2022. Mangrove area in 2005is 28.89 ha, 2010 is 81.38 ha, 2015 is 180.27 ha, and 2022 is 121.34 ha. It can be seen that there is a decreasing ofmangrove area from 2015 to 2022. The analysis results are also able to show that Kuta raja sub district has thelargest mangrove area of 60.11 ha or 49.54 % of the overall area. According to the overall results, it can be said that remote sensing satellite images such as Landsat and Sentinel 2A are very useful in conducting the spatio-temporal research from the long-term periods. This study is hoped to be able to become a reference data in efforts to restore the mangrove in Banda Aceh in order to create the sustainable ecosystem area.Keywords:Mangrove ecosystemsRestorationNDVISupervised classificationSpatio temporal
