The development area always gives significant impacts on the population, resulting in higher land requirements. In the end, it can trigger an increase in land conversion for settlements, industrial estates, facilities, infrastructure, and other activities.

Conversion of mangrove forests is one form of land conversion that cannot be avoided in coastal areas and small islands due to uncontrolled population growth in an area. This encourages damage to coastal and marine resources, which will have a negative impact on human life.

The existence of mangrove forests in the coastal areas of Pasuruan Regency precisely in the coastal areas of Kedawang District administration continues to experience damage or degradation. It is caused by various pressures in the use and management that do not pay attention to aspects of sustainability. In some areas north of the mangrove in Pasuruan Regency already experienced quite alarming damage.

As an initial effort to prevent and mitigate damage to mangrove ecosystems, accurate data, and information about ecosystem conditions, including identification and inventory of the existing biophysical conditions of mangrove ecosystems in an area is needed. Accurate data on the actual condition of mangroves on the coast of Kedawang Village is now needed as a baseline and a reference for sustainable management programs.

Biophysical information is collected through image analysis and Geographic Information System (GIS) analysis and followed by verification through direct field surveys using the transect method for vegetation analysis. Supporting data such as the results of previous studies and data from agencies have been reviewed as a comparison of the current condition of the mangrove ecosystem.

Data collection is done by measurement and direct observation (observation) and sampling. Biophysical measurement parameters of mangrove ecosystems in the field consist of (a) mangrove species, (b) mangrove density. The data that has been collected is then tabulated and analyzed descriptively qualitatively.

From the research conducted, it was found that the study area was divided into three stations, namely station 1, station 2, and station 3. Several types of mangroves were found, among others, Avicennia alba, Avicennia Marina, Sonneratia Alba, Rhizophora mucronata, and Rhizophora apiculata. From all the research stations observed, Avicennia alba grew.

The results of soil texture measurements at stations 1 and 2 have sandy clay texture because stations 1 and 2 face the sea. While the texture of the ground station 3 is clay. This is expected because station 3 is more influenced by land and population activities. Information related to mangrove species diversity and density can be used as an alternative to the recovery of fisheries and coastal resources in Indonesian waters.
