Simbiosis Zooxanthellae Dan Karang Sebagai Indikator Kualitas Ekosistem Terumbu Karang

TINJAUAN TEORITIS SIMBIOSIS ZOOXANTHELLAE DAN KARANG SEBAGAI INDIKATOR KUALITAS EKOSISTEM TERUMBU KARANG Unstain NWJ Rembet1 ABSTRACT A symbiotic process between zooxanthellae and corals can support the adaptative factors in terms of natural vulnerability criteria. The proposed consideration are 1) the symbiosis between zooxanthellae and corals provides phenomenal contributions to coral evolutionary process and 2) the criteria used by Gomez and Yap have been merely based on live coral cover that is still becoming key tools for the evaluation of coral reef health status measure. These criteria have been weaker and weaker due to neglecting the feature of intra- and interspesific relationship in coral biota itself. Therefore, the use of zooxanthellae and coral symbiotic relationship is thought of being able to complete the coral reef quality evaluation since its information could address this relationship feature beside on the basis of response to environmental pressures. Keywords : symbiotic, zooxanthellae, coral. ABSTRAK Proses simbiosis antara zooxanthellae dengan karang dapat memberikan suatu support terhadap faktor penyesuai dalam hal ini dari segi kriteria kerentanan alami. Pertimbangan yang diajukan adalah (1) simbiosis antara karang dengan zooxanthellae memberikan konstribusi fenomenal dalam proses evolusi karang dan (2) kriteria yang dipergunakan saat ini dari analisis Gomez dan Yap hanya didasarkan atas tutupan karang hidup yang sampai sekarang menjadi acuan bagi evaluasi tingkat status kesehatan terumbu. Kriteria tersebut dipandang mengalami kelemahan karena mengabaikan sifat hubungan intra dan ekstraspesifik dari biota karang itu sendiri. Atas dasar hal tersebut, maka penggunaan hubungan simbiosis zoxanthellae dan karang dipandang dapat melengkapi evaluasi kualitas terumbu karang karena informasinya dapat menjelaskan sifat hubungan intra dan ekstra spesifik, disamping atas dasar respon terhadap tekanan lingkungan.

Pembangunan Wilayah Pesisir Dan Lautan Dalam Perspektif Negara Kepulauan Republik Indonesia

PEMBANGUNAN WILAYAH PESISIR DAN LAUTAN DALAM PERSPEKTIF NEGARA KEPULAUAN REPUBLIK INDONESIA Regional Development in Coastal and Ocean in Archipelago Perspective of The Republic of Indonesia Ridwan Lasabuda1 ABSTRACT Indonesian as an archipelagic state has been recognized Internationally (UNCLOS 1982), later ratified by Act 17 of 1985. Under UNCLOS 1982, the total maritime area of Indonesia is 5.9 million km2, consisting of 3.2 million km2 of territorial waters and 2.7 km2 of Economic Exclusive Zone (Zone Ekonomi Ekslusif), not including the continental shelf. This makes Indonesia as the largest archipelagic state in the world. However, the development of marine and fisheries for this is still far from expectations, while large potential of natural resources and environmental services are relatively unexploited in coastal areas, small islands and ocean in Indonesian archipelago.

The Growth Rate of Acropora SP. Transplanted on Artificial Reefs in Kareko Waters of North Lembeh Sub-District of Bitung City

The purpose of this research is to know the success rate of Acropora sp coral growth rate transplanted on different artificial reefs (iron and concrete) in Kareko waters of North Lembeh Sub-district of Bitung City. The study was conducted in November 2016 - February 2017. The data were collected by SCUBA divers and counted the number of dead and surviving coral transplants and measured the absolute length increase for each month. The results showed that the survival rate and the growth rate of coral transplant of iron-made reefs were 70% (survival rate) and 1.00 cm / month (growth rate), while artificial reefs were recorded had 50% (survival rate) and 0.93 cm / month (growth rate). Coral transplant growth rates on different substrates (iron and concrete) were not significantly different (P> 0.05).
