This affects the position of the coastline at Tanjung Siambang Beach from year to year, so it is necessary to conduct research to monitor shoreline changes that occur on the beach. This study aims to determine the distance and rate of change of coastline that occurs at Tanjung Siambang Beach using Sentinel-2A satellite imagery. The methods used to calculate shoreline changes are the Net Shoreline Movement (NSM) and End Point Rate (EPR) methods contained in the Digital Shoreline Analysis System (DSAS). The results showed that during the last 5 years, Tanjung Siambang Beach experienced abrasion with an average change of -10.18 meters at a rate of -2.12 meters/year. Accretion also occurs near river mouths with an average accretion rate of 1.43 meters and a rate of 0.3 meters/year. Overall, in the 2016-2021 period Tanjung Siambang Beach has predominantly experienced land reduction (abrasion). Utilization of remote sensing data and various remote sensing data processing software is very useful for providing information about changes in the coastline that will be useful in making policies related to development in coastal areas as well as prevention or mitigation of possible disasters that will occur in these coastal areas.","PeriodicalId":17689,"journal":{"name":"Jurnal Kelautan: Indonesian Journal of Marine Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139347604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mangroves are one of the productive ecosystems whose primary production consists of litter, decomposition and nutrients. The high productivity of mangroves will be related to the food chain that depends on decomposed litter. This study aims to determine the relationship between mangrove density and litter production rate in the Muara Badak Kutai Kartanegara area, East Kalimantan.
