A feasibility study of prepubertal and over mature aged local goat in relation to results of In Vitro growth culture to obtain additional M-II oocyte resources AIP Conference Proceedings 1908, 020001 (2017) Abstract. Research on coral microstructure in Indonesia, especially in East Java is rarely done. Therefore, this study aims to examine the shape of Aragonite Crystal coral Porites lutea in Pantai Kondak Merak, East Java, especially in 1998 which is the time of El Nino and has a global impact on coral growth. The shape of the aragonite crystal on the reef can be seen using the Scanning Electron Microscopy-Energy Dispersion X-Ray (SEM -EDX). Based on the coral aragonite crystal form, the increasing temperature in 1998 was not proven to have a devastating effect on the growth of corals of Pantai Kondang Merak. In contrast, the temperature at this site should support corals in order to grow rapidly, but there are other environmental factors that ultimately inhibit the growth of the coral.

The aim of this research was to evaluate the coral reef condition in Sempu's strait. This research has beeb conducted at December 2017 used PIT method in four research stations i.e. Teluk Semut 1, Teluk Semut 2, Watu Meja and Fish Apartement. In generally the substrate of Sempu strait was devided into two categories, they were living and non-living substrate. Living substrate include HC, SC, NIA, SP and OT while non-living were RKC, RC, RB, SD and SI. Station 1 was dominated by hard coral (33.75%), station 2 and 3 was by rock (59.38% and 40.63%), and station 4 was dominated by sand (39.38%) respectively. Based on the monitoring, the coral reefs ecosystem of Sempu Strait was categorised in damaged condition. It could be seen by the high covering of dead coral and the low covering of healthy coral along observed stations. The coral reefs rehabilitation program is needed to recover the reefs ecosystem in Sempu Strait.

Conservation is one the way for resource management of vulnerable natural resources. Nature Conservation Forum Putri Menjangan is a group of people who have an interest in the management of natural resources, especially on mangrove ecosystems and coral reef ecosystems, in addition to conservation activities is also carried out data collection species start from mangrove, coral reef, reef fishes and other organisms that live in Putri Menjangan waters. Mangrove forest conservation is done through reforestation in areas which have a low mangrove cover, whereas for coral reef conservation activities carried out through coral transplantation and garbage clean up activity in coral reef ecosystems both of trash and competitor organism found on coral reef ecosystems.Keywords: community based management, mangrove, coral reef ABSTRAK Konservasi merupakan salah satu bentuk pengelolaan sumberdaya alam yang telah mengalami kerusakan. Terdapat berbagai macam jenis pengelolaan kawasan salah satu jenis pengelolaan itu adalah pengelolaan berbasis masyarakat atau Community Based Management. Nature Conservation Forum Putri menjangan merupakan kelompok masyarakat yang memiliki ketertarikan dalam pengelolaan kelestarian alam khusunya pada ekosistem mangrove dan ekosistem terumbu karang. Kegiatan konservasi hutan mangrove dilakukan dengan cara reboisasi atau penanaman mangrove di daerah yang memiliki tutupan mangrove yang rendah, sedangkan untuk konservasi terumbu karang dilakukan melalui kegiatan transplantasi terumbu karang dan kegiatan clean up di kawasan ekosistem terumbu karang baik dari sampah maupun biota-biota kompetitor yang terdapat pada ekosistem terumbu karang.Kata kunci: manajemen berbasis masyarakat, mangrove, terumbu karang PENDAHULUAN Konservasi sumber daya hayati laut merupakan salah satu bentuk pemulihan ekosistem yang telah mengalami kerusakan. Kerusakan yang terjadi biasanya diakibatkan oleh pemanfaatan sumber daya alam yang tidak terkendali, selain itu sistem pengelolaan yang kurang maksimal juga merupakan salah satu faktor yang dapat menyebabkan terjadinya kerusakan (Damanik et al., 2006).Organisasi Nature Conservation Forum Putri Menjangan (NCF Putri Menjangan) merupakan suatu organisasi yang terbentuk dari sekumpulan warga atau individu yang berasal dari beberapa komunitas lingkungan kelautan yang memiliki ketertarikan dalam bidang pengembangan dan pelestarian potensi hutan mangrove dan sumberdaya kelautan dalam bentuk pengelolaan dan pemanfaatan lingkungan yang berkesinambungan dengan dasar kelestarian lingkungan dan pemberdayaan masyarakat sekitar (NCF Putri Menjangan, 2016).

Coral reef have very important function for supporting activity in coastal areas. Recently the existence of coral has been degraded and faced threat from bath of antropogenics and natural factor. Predation, bioerosion and competitor among sessil organism has been to be the most lichtiest problem that really direct impact on coral reef. Data has been take by using of quadrant transect and reef check megabenthos metod in two research stations. The results showed that the organism competitors coral reefs in the waters of Putri Menjangan include macro algae, crown of thorns fish and Drupella.
