This study provides an overview of the potential of endophytic fungi isolated from leaves, stems, mangrove roots A. marina as a producer of antibiotics tested for Staphylococcus aureus, Escherichia coli, Candida albicans. This research was carried out in the microbiology laboratory of the Health Polytechnic of the Ministry of Health of Riau from March to June 2017. This study used a laboratory experimental method, the data presented in descriptive form. The stages of the study were: identification of A. marina plants, fungal isolation, qualitative tests of flavonoids isolates from endophytic fungal, and antibacterial activity test. The results showed that from 15 isolates of endophytic fungi, 5 isolates producing antibiotics. FAA 3 isolate showed the highest antibiotic activity with 24 mm the diameter of the inhibitory zone, while the lowest inhibition zone was FAA 4 isolate by forming a diameter of inhibitory zone of 7 mm and the results of qualitative tests of metabolites showed as secondary flvonoid metabolites. This research can be used as a source of information for the community in utilizing mangrove plants as an alternative in improving health.

Mangrove plays important role in the coastal ecosystem worldwide, and Indonesia as an archipelagic country occupies about 27% of the global mangrove area. Unfortunately, about 48% of areas of Indonesia’s mangroves have been damaged. Human, biophysics and climate stressors are found to affect the mangrove damages. Using a case study of Pekalongan and Demak, i.e., the prioritized locations for mangrove rehabilitation in Indonesia, this study translated the contributing stressors into quantifiable indicators that can be used to measure the risks. The risk framework on climate change assessment and ecological sensitive evaluation was employed to define the measured indicators and parameters. The indicators were classified into distinctive groups of hazards, exposures, and vulnerability which were composed of sensitivity and capacity. The indicators are then defined with regards to the existence of mangroves as an individual (vegetation), habitat, and ecosystem, and a set of parameters constitute the indicators measured the stressors of socio-economics, biophysics, and climate were determined with regards to the data availability and requirements. The measured indicators can be helpful to identify what strategies or actions should be devised to address the most contributing indicators to the mangrove risks and may be replicated to other coastal areas in the tropical regions.
