Recently, the Local Government of Sukabumi District has taken measures to manage the beach as a "Coastal Park" in order to promote sea turtle conservation. In context, the development of green turtle conservation has been managed as follows: management activity started in 1907 under license from the Dutch Colonial Government. The management implementation was initiated effectively in 1957 using an auction system, with a total management area of 12,300 m 2 established. In 1989, the area of Pangumbahan at about 115 ha, with its 3,000m long and 500m wide beach, was determined to be under the rightful management of the Marine Affairs and Fisheries Service of Sukabumi District. During this period, the technical sea turtle management has beenimplemented by a private company. From the beginning of April 2008 to the present, the management of the beach has been taken over by the Sukabumi District Government which charges the Marine Affairs and Fisheries Service as responsible for managing the park. The positive impact appears in several indicators including data gathering, non utilisation of eggs for any purpose, improvement of hatching rate, an increase in hatchling numbers released into the sea and open access for visitors, which tends to increase year by year. This positive management example would be valuable to turtle conservation in Indonesia.

This study aimed to assess the reef fishes community structure at small islands in Paraja Bay. Observations were made in 20 locations during August and September 2019 in the five small islands. Reef fishes community structure showed 106 species as included major group (54 species), indicator group (24 species) and target group (28 species), among five small islands, i.e. Badul, M angir, Oar, Sumur and Umang Islands. The highest reef fishes abundance was founded in Umang Island waters. Several target fish species recorded during the study were mature fish (such as those targeted by fishermen). Only a small proportion were juveniles. Reef fish community structure was categorized as stress community to stable community with its indication was low diversity value, high evenness index, and low dominance. The low diversity index value illustrates that the level of uniformity of reef fish species in Paraja Bay waters is high. This condition is evidenced by each coral fish group's evenness index included in the main species group around 0.93 to 0.98. The target species is 0.88 to 0.99.

In addition, the sustainability of fishery resources is maintained, as people in Savu Sea depend on fishery resources. The objectives of this research are to analyse the effectiveness of sub-zone cetacean protection for Savu Sea National Marien Park. The research stations were watering inside and outside in Savu Sea National Marine Park. The sampling of the research was conducted on 2015 and 2016, collecting data using a zig-zag transect by observation method of collecting data sighting cetacean with single observer platform. The results of sub-zone cetacean protection against Southwest Sumba waters, West Sumba and East Timor Land need to be reviewed if referring the current zoning area. Sub-zone for areas to protect sustainability cetacean need to be adjusted addition and alteration of fishery zone, the area of Southwest Sumba, West Sumba and Central Sumba is ± 445,567.44...

This area is mainly comprises of disturb coastal old secondary forest. Some sites along the seashore were converted into fishpond, dry land agricultural and other was destroyed for other uses or as an open unproductive areas. However this area has a still plays an important role especially for the conservation of green turtle habitat and also for the ecosystem stabilization of the coastal area in general. Floristic research was conducted on September 2009 to investigate the existing vegetation structure and composition along the seashore using transects method.The “point center quarters method†was used to calculate the importance value of the vegetation on every turtle nesting sites. The important natural species vegetation communities in the area were comprises of herbs, shrubs and trees species. Ipoemoea pes-caprae (L.) R. Br and Spinifex littoreus (N. L...

Recently, the Local Government of Sukabumi District has taken measures to manage the beach as a "Coastal Park" in order to promote sea turtle conservation. In context, the development of green turtle conservation has been managed as follows: management activity started in 1907 under license from the Dutch Colonial Government. The management implementation was initiated effectively in 1957 using an auction system, with a total management area of 12,300 m 2 established. In 1989, the area of Pangumbahan at about 115 ha, with its 3,000m long and 500m wide beach, was determined to be under the rightful management of the Marine Affairs and Fisheries Service of Sukabumi District. During this period, the technical sea turtle management has beenimplemented by a private company. From the beginning of April 2008 to the present, the management of the beach has been taken over by the Sukabumi District Government which charges the Marine Affairs and Fisheries Service as responsible for managing the park. The positive impact appears in several indicators including data gathering, non utilisation of eggs for any purpose, improvement of hatching rate, an increase in hatchling numbers released into the sea and open access for visitors, which tends to increase year by year. This positive management example would be valuable to turtle conservation in Indonesia.

This study aimed to assess the reef fishes community structure at small islands in Paraja Bay. Observations were made in 20 locations during August and September 2019 in the five small islands. Reef fishes community structure showed 106 species as included major group (54 species), indicator group (24 species) and target group (28 species), among five small islands, i.e. Badul, M angir, Oar, Sumur and Umang Islands. The highest reef fishes abundance was founded in Umang Island waters. Several target fish species recorded during the study were mature fish (such as those targeted by fishermen). Only a small proportion were juveniles. Reef fish community structure was categorized as stress community to stable community with its indication was low diversity value, high evenness index, and low dominance. The low diversity index value illustrates that the level of uniformity of reef fish species in Paraja Bay waters is high. This condition is evidenced by each coral fish group's evenness index included in the main species group around 0.93 to 0.98. The target species is 0.88 to 0.99.
