Coral reefs are one of the typical ecosystems in coastal areas that have ecological and economicvalue. There are many cases of coral reef damage in Salah Nama Island caused by natural andhuman factors. Coral reefs damage is mostly caused by human activities such as water pollution,destructive fishing and using of ship anchors. Activity of devotion society aims to provideinformation and skills to fishermen groups in Salah Nama Island about coral transplantationtechniques, as well as conducting coral transplantation activities as one of the efforts to preservethe ecosystem of coral reefs. Based on the description of the problems and objectives of devotionsociety, the activities that have been done are counseling to the partner fishermen abouttransplantation and coral benefits in ecosystem, transplantation practice and coral transplantationmonitoring.

Reef Ecosystem

The coral reef ecosystem is one of the typical tropical ecosystems with high biodiversity which has an important role both biologically, ecologically, physically as well as socially and economically. Several coral reef areas in Indonesia were reported to have suffered damage, not only due to climate change which has an impact on rising sea surface temperatures and ocean acidification but also due to anthropogenic factors and irresponsible management of marine tourism. This study aimed to analyze the condition of coral reefs based on covering in Pramuka Island, which is one of the famous tourist destinations in the Seribu Islands. The study was conducted using Line Intercept Transect (LIT) method at predetermined coordinate points. The results showed that the dominant coral reef life form was Acropora Submassive (ACS), namely 18.9%, and Acropora Branching (ACB) as much as 12.48%. Besides, the types of life forms found were coral foliase (9.42%), Miliepora Coral (9.2%), Coral Massive (4.8%), Acropora Encrustring (4.24%), and so on. Based on the results of this study, it can be concluded that the condition of coral reefs in Pramuka Island is still relatively good with a total coral cover percentage of 72.38%. Efforts to protect the coral reef ecosystem in this area need to be considered so that its condition can be maintained.

Reef Ecosystem

Conservation effort and knowledge on coral reef ecosystem are necessary to protect marine ecosystem. Coral reef ecosystem is very important to support marine biota especially fishes and benthos. The presence of coral reef indirectly support local people income, therefore is is necessary to conserve coral reef ecosystem. District of South Waigeo is one of tourist area as well as preserve area in Raja Ampat Regency of Papua Barat Province. The aim of this study is to identify the current condition of coral reef in Saporken Village of South waigeo District. Data were collected by survey method using coral reefs Point intercept transect method, observation and interviews to determine the social, economic and cultural impact., and measures taken to manage coral reef management in village Saporkren Marine Protected Areas. The results showed that knowledge Saporkren Village community, the conservation community knows about how destructive such arrests are not carried out the bombing, while the traditional way people work is local wisdom. Condition of coral cover in the village of Marine Protected Areas Saporkren in good condition (live coral cover=51%) and very good water quality, flow velocity at high tide ranged from 4.25 to 22.3 cm/sec and the flow velocity at low tide over small ranging from 5.07 to 19.60 cm/sec, salinity ranged from 32–35‰ and wave height ranged from 0.75 m. Based on the results of this study concluded that: Village community know Saporkren conservation activities of local government programs, and the traditional way to preserve coral reef still implemented.Key words: Conservation, coral reefs, Saporkren village, Raja Ampat.

Reef Ecosystem

Coral reefs are some of the most important and ecologically diverse marine environments. At the base of the reef ecosystem are dinoflagellate algae, which live symbiotically within coral cells. Efforts to understand the relationship between alga and coral have been greatly hampered by the lack of an appropriate dinoflagellate genetic transformation technology. By making use of the plasmid-like fragmented chloroplast genome, we have introduced novel genetic material into the dinoflagellate chloroplast genome. We have shown that the introduced genes are expressed and confer the expected phenotypes. Genetically modified cultures have been grown for 1 year with subculturing, maintaining the introduced genes and phenotypes. This indicates that cells continue to divide after transformation and that the transformation is stable. This is the first report of stable chloroplast transformation in dinoflagellate algae.
