Abstract: Mangkang Kulon Subdistrict is one of the coastal areas in Semarang that has relatively dynamic conditions, which seen from the coastline and mangrove ecosystem changes within several years of observation. This study aims to observe coastline changes and the spatial distribution of mangrove ecosystems on the coast of Mangkang Kulon Subdistrict between 2005, 2012 and 2019. Land use n were obtained from visual interpretation of high-resolution digital globe satellite images from 2005, 2012, and 2019 which then tested the accuracy of land use interpretation through field observation and overlaid one another through vector analysis to find out the changes that have occurred. The study showed that the coastline changes were increasingly jutting towards the land in this range of time. This condition is affected by the port construction on the east coast of the Kendal Regency, which directly adjacent to the Mangkang Kulon Subdistrict. Meanwhile, the mangrove ecosystem has increased widely with relatively elongated and grouped spatial patterns. The increase that occurred as a manifestation of various coastal care activities in the form of mangrove planting activities carried out by several government agencies and private parties with a model of coastal community empowerment.
