Abstract

SAKILA AZRIL LIA. Estimasi Stok Karbon Biomassa Mangrove Menggunakan Kombinasi Metode Alometrik dan Spasial di Ekowisata Mangrovesari, Brebes, Jawa Tengah. Dibimbing oleh FERY KURNIAWAN dan ARIO DAMAR. Mangrove berpotensi untuk menyerap dan menyimpan karbon lima kali lebih efektif dari rata-rata simpanan karbon hutan tropis. Upaya rehabilitasi yang dilakukan oleh pengelola Mangrovesari berdampak positif dalam menambah luasan hutan mangrove secara signifikan. Penelitian ini bertujuan untuk mengestimasi stok karbon total ekosistem mangrove menggunakan pendekatan integrasi alometrik dan spasial di ekowisata Mangrovesari, Desa Kaliwlingi, Brebes, Jawa Tengah. Hasil penelitian menunjukkan bahwa spesies mangrove yang mendominasi di ekowisata Mangrovesari adalah Rhizophora mucronata. Faktor lingkungan seperti suhu, pH, salinitas, dan DO serta tipe substrat berpengaruh terhadap kerapatan mangrove. Kerapatan mangrove memiliki pengaruh positif terhadap biomassa dan stok karbon mangrove. Nilai stok karbon mangrove di ekowisata Mangrovesari dikelompokan ke dalam 3 kategori kerapatan mangrove. Mangrove dengan kategori jarang mengandung stok karbon sebesar 42,02 ton/ha, kategori sedang sebesar 26,61 ton/ha, kategori rapat sebesar 444,60 ton/ha, dan stok karbon mangrove total sebesar 513,2334 ton/ha. Kata kunci: alometrik, biomassa, karbon, mangrove, spasial

SAKILA AZRIL LIA. Estimation of Stock Carbon Mangrove Biomass Using a Combination of Allometric and Spatial Methods in Mangrovesari Ecotourism, Brebes, Central Java Supervised by FERY KURNIAWAN and ARIO DAMAR. Mangroves have the potential to absorb and store carbon five times more effectively than the average tropical forest carbon storage. Rehabilitation efforts carried out by Mangrovesari managers have a positive impact in significantly increasing the area of mangrove forests. This study aims to estimate the total carbon stock of mangrove ecosystems using allometric and spatial integration approaches in Mangrovesari ecotourism, Kaliwlingi Village, Brebes, Central Java. The results showed that the dominating mangrove species in Mangrovesari ecotourism was Rhizophora mucronata. Environmental factors such as temperature, pH, salinity, and DO as well as substrate type affect mangrove density. Mangrove density has a positive influence on mangrove biomass and carbon stock. Mangrove carbon stock values in Mangrovesari ecotourism are grouped into 3 categories of mangrove density. Mangroves with sparse categories contain carbon stock of 42,02 tons/ha, medium category of 26,61 tons/ha, dense category of 444,60 tons/ha, and total mangrove carbon stock of 513,23 tons/ha.
