Kasdiningsih, Widya Raranata Cahya and Prof. Dr. Rudianto,, MA and Dian Aliviyanti,, S.Si. M.Si (2024) Analisis Estimasi Penyerapan Dan Penyimpanan Karbon Terumbu Karang Di Perairan Gili Noko, Bawean. Sarjana thesis, Universitas Brawijaya.
Abstract
Terumbu karang merupakan sebuah ekosistem yang sangat berjasa bagi lingkungan. Terumbu karang memiliki peran penting dalam ekologis, berfungsi sebagai tempat perlindungan biota, pencegah abrasi, bahkan sebagai objek pariwisata. Perbincangan mengenai penyerapan karbon oleh terumbu karang semakin ramai diperbincangkan dalam penelitian global. Belum banyak penelitian yang menjelaskan apakah karang dapat menyerap dan menyimpan karbon sama halnya seperti tumbuhan. Karbon di bumi semakin bertambah seiring berjalannya waktu, tentunya hal ini menjadi masalah penting yang harus diatasi. Oleh sebab itu, para peneliti memiliki banyak pertanyaan terkait penyerapan karbon pada karang. Kabarnya, laut menyerap karbon sebanyak 26% dari keseluruhan emisi. Penelitian dilakukan pada bulan Maret hingga April 2024, mencakup persiapan, pengambilan data lapang dan analisis laboratorium. Lokasi penelitian berada di Perairan Pulau Gili Noko, Kepulauan Bawean. Analisis laboratorium dilakukan di Laboratorium Eksplorasi Sumberdaya Perikanan dan Kelautan serta Laboratorium Perekayasaan Hasil Perikanan. Data lapang yang diambil berupa sampel karang Acropora Branching, Acropora Tabulate, Acropora Digitate serta data kualitas perairan dari empat stasiun. Analisis kadar karbon menggunakan metode LOI yang dilakukan di laboratorium untuk mengetahui persentase TOC pada sampel karang. Data distribusi komunitas terumbu karang juga diambil menggunakan metode LIT. Hasil penelitian menunjukkan bahwa persentase rata-rata Total Organic Carbon dari Acropora Branching adalah 2,17 %, Acropora Tabulate 1,33%, dan Acropora Digitate 2,50%. Persentase tutupan karang hidup sebesar 44,89%, sedangkan non-living sebesar 55,11%. Distribusi karang hidup didominasi oleh bentuk pertumbuhan Coral Massive, Acropora Submassif, dan Acroporan Digitate. Bentuk pertumbuhan non-living didominasi oleh Death Coral with Algae, Rock, Rubble.
English Abstract
Coral reefs are an ecosystem that is very useful for the environment. Coral reefs have an important role in ecology, functioning as a refuge for biota, abrasion prevention, and even as an object of tourism. Coral reefs have their own beauty that can attract tourists to visit. Conversations about carbon sequestration by coral reefs are increasingly being discussed in global research. Not many studies have explained whether coral can absorb and store carbon just like plants. Carbon on earth is increasing over time, of course, this is an important problem that must be addressed. That's why researchers are curious and have questions about carbon sequestration in corals. Reportedly, the ocean absorbs carbon as much as 26% of overall emissions. The research was conducted from March to April 2024, including preparation, field data collection and laboratory analysis. The research location was in the waters of Gili Noko Island, Bawean Islands. Laboratory analysis was carried out at the Fisheries and Marine Resources Exploration Laboratory and the Fishery Products Engineering Laboratory. Field data taken in the form of coral samples Acropora Branching, Acropora Tabulate, Acropora Digitate and water quality data from four stations. Carbon content analysis using the LOI method was carried out in the laboratory to determine the percentage of TOC in coral samples. Coral reef community distribution data were also taken using the LIT method. The results showed that the average percentage of Total Organic Carbon from Acropora Branching was 2.17%, Acropora Tabulate 1.33%, and Acropora Digitate 2.50%. The percentage of live coral cover was 44.89%, while non-living was 55.11%. The distribution of living corals was dominated by Coral Massive, Acropora Submassif, and Acroporan Digitate growth forms. Non-living growth forms are dominated by Death Coral with Algae, Rock, Rubble. Tourism activities still fulfil the carrying capacity of the area, so there is no significant impact of activities.
