Measurement of Indonesian Marine Health Index to Assess The Health of The Coastal Ecosystem of Tuban, East Java

The purpose of this study is to assess marine health on the scale of coastal water and reveal its potential to provide a benchmark for sustainable marine development activities in Tuban Regency.
