    abstract = {The condition of mangrove ecosystem is fluctuated due to the various factors such as the
environmental support, replanting, maintenance, natural disturbance and anthropogenic effects. This research
aimed to understand the change of mangrove coverage between 2011 and 2016 in Semarang and Demak and
analyze the change of mangrove proportions based on the damage level. The research was conducted in
October 2017 through literature study to obtain information of the condition of mangrove ecosystem in
Semarang city and Demak Regency in 2011 and 2016. Data analysis was conducted with Chi-square test to
understand the change of coverage proportion based on the degradation level. The result shows that the
mangrove coverage of Demak Regency was increased from 3.950 ha in 2011-4.595 ha in 2016 while the coverage
in Semarang city was static with 325 ha. Increased mangrove coverage was occurred in Demak and Semarang
both for the good and poor condition of mangrove. Contrarily, the coverage of mangrove with moderate
condition was reduced. Statistically, the proportions of mangrove conditions were significantly different.
Mangrove coverage in Demak and Semarang should be improved to recover the mangrove ecosystem which
has been destructed.}
