Abstract. Aulia ED, Hadi TA, Utama RS. 2021. Sponge community (Porifera) in coral reef ecosystem in Sabang, Aceh Province, Indonesia. Biodiversitas 22: 3394-3402. Sponges are one of the most influential benthic organisms in coral reef ecosystems. Many studies about sponge communities have been carried out globally, from tropical to temperate regions. In Indonesia, however, sponge communities have not been adequately observed, especially their diversity and interaction with habitats. Sabang, a developing city located in the northwest of Indonesia, has a lack of information about benthic communities and no reports about sponges. This study investigated the sponge community (species richness, coverage, and morphological characters) and the interactions, both within sponges and with corals and substrates, in Sabang. The study found that the sponge richness (species and morphology) and coverage are categorized as poor, having only 24 species with seven morphologies, and coverage of 1.79 ± 1.03% (SE). The interaction analyses showed significant relationships occur among sponge variables but not between sponges and corals, nor between sponges and their substrates. These results could be attributed to the hydrodynamic-related stresses in Sabang, which are likely influenced by exposure to the open ocean, a condition that is less favorable to diversity and interaction. It is necessary to regularly monitor the condition of benthic communities in Sabang in order to better understand their stable state and detect any change over time.

Penempatan reef ball di perairan Teluk Buyat dan sekitarnya telah dilakukan pada tahun 1999 oleh PT. Newmont Minahasa Raya. Tujuan penempatan reef ball untuk membangun habitat berbagai biota yang berasosiasi dengan karang sehingga dapat meningkatkan populasi ikan ekonomis penting. Kehadiran ikan karang pada reef ball sangat penting secara ekologis dan ekonomis. Penurunan kualitas terumbu berarti hilangnya nilai ekonomi barang dan jasa, serta hilangnya jaminan makanan dan pekerjaan untuk masyarakat pesisir, yang umumnya hidup dalam kemiskinan. Secara keseluruan, komposisi spesies ikan yang ditemukan di reef ball terdiri dari 19 famili, 34 genus, 50 spesies dan 290 individu, yang tertinggi dihuni oleh jenis dari famili Mullidae. Seiring dengan bertambahnya waktu dan usia reef ball, beberapa spesies terlihat sudah menetap seperti Lutjanus kasmira, dan beberapa spesies dari famili Acanthuridae. Keberadaan reef ball membantu terbentuknya ekosistem terumbu karang yang baru dan meningkatkan kesuburan perairan, sehingga lebih meningkatkan keberadaan komposisi ikan karang, yang pada akhirnya meningkatkan pendapatan nelayan dari hasil tangkapan ikan karang.Kata kunci: Reef ball, karang batu, ikan karang Distribution of Coral Reefs and Fish in Buyat Bay Area Reef Ball Southeast Minahasa Regency The placement of reef ball in Buyat Bay and surrounding areas have been carried out since 1999 by PT. Newmont Minahasa Raya. The goal of this placement was to build a habitat for many biota associated with reef thus may improve economically important fish populations. The presence of reef fish on the reef ball is indispensable ecologically and economically. Furthermore, the degradation of reefs might cause the disappearance of economic value of goods and services, as well as the disappearance of food security and employment for coastal communities, who generally live in poverty. Overall, the composition of fish species found in the reef ball consists of 19 families, 34 genera, 50 species and 290 individuals, the highest inhabited by species of the family Mullidae. As time went by and the increase of reef ball age, some species seem have settled down such as Lutjanus kasmira, and several species of the Acanthuridae family. In addition, the presence of reef ball helps the formation of a new coral reef ecosystem and increase the fertility of waters, therefore enhancing the presence of reef fish composition, which might increases the income of fishermen.

Coral reefs are ecosystems with high productivity while being very vulnerable to environmental changes. The oil spill incident in Balikpapan Bay in 2018 still caused damage to the coral reef ecosystem in Tanjung Jumlai, Penajam Paser Utara Regency, East Kalimantan due to the use of dispersants in handling oil spills. Research on the condition of coral reefs is carried out to ensure the sustainability of the benefits of ecosystem products and services provided by coral reef ecosystems to communities around Balikpapan Bay. Coral reef research has been carried out at three transect station locations in the Tanjung Jumlai reef area. This research is aimed to determine the distribution, abundance, and structure of coral reef ecosystems in these waters. The study was conducted in October 2019. Data collection was carried out using the Point Intercept Transect (PIT) method. The results showed that the average percentage of coral cover was 55.7% with a good coral cover category. Substrate covering the bottom of the coral reef ecosystem is dominated by Acropora Tubulate and Acropora Branching from the biotic component, and Dead Coral with Algae and Rubble from the abiotic component. Diversity index value (H') in the waters is categorized as low species richness. This research has been identified only 10 genera in the study area where 9 genera are hard coral species. Similarity Index value (E) included in the medium category and dominance index value (D) belong to the medium category which means that there are no species that are very dominant in the observation area. Water quality at station 1 representing all observation stations shows results that the study area are still appropriate for marine biota according to Minister of Environment Decree 51/2004, except for nitrate content. Sediments also show no trace of hydrocarbons.Coral reefs are ecosystems with high productivity while being very vulnerable to environmental changes.
