Abstract

Penelitian ini dilaksanakan pada bulan Februari – Maret 2024 yang berlokasi di Muara Sungai Desa Mengkapan, Kecamatan Sungai Apit, Kabupaten Siak. Tujuan penelitian ini adalah untuk mengetahui nilai kerapatan, biomassa, stok karbon dan serapan CO₂, serta untuk mengetahui hubungan kerapatan dengan biomassa, stok karbon dan serapan CO₂ mangrove. Metode yang digunakan adalah metode survei. Pada lokasi penelitian ditemukan 3 jenis spesies yaitu Avicennia alba, Rhizophora apiculata, dan Sonneratia alba. jumlah rata-rata kerapatan tegakan mangrove di ketiga stasiun penelitian adalah 1.218,52 ind/ha, jumlah rata-rata biomassa mangrove 303,08 ton/ha, jumlah rata-rata stok karbon mangrove 142,45 ton/ha. Rata-rata jumlah stok karbon sedimen 2.756,80 ton/ha dan jumlah serapan CO₂ rata-rata 521,23 ton/ha. Hubungan kerapatan mangrove terhadap biomassa, stok karbon dan serapan CO₂ memiliki hubungan yang sedang antara kerapatan tegakan mangrove dengan biomassa mangrove, kandungan karbon dan serapan CO₂. Hal ini dikarenakan tingginya biomassa, stok karbon dan serapan CO₂  tidak hanya dipengaruhi oleh kerapatan tapi dipengaruhi oleh faktor lain seperti besarnya diameter pohon, umur tanaman, tingkat kesuburan sedimen atau habitat tempat tumbuh pohon

Abstract

Anadara granosa is one of the bivalves that are often found in public markets. This study aimed to study the relationship between length-weight and sex ratio of blood clams (A. granosa) in the coastal waters of West Rangsang. Sampling was carried out every month at three stations. Shells were collected from a 1 x 1 m2 plot on a quadratic transect. The relationship between length and weight was analyzed by regression analysis. The sex ratio between the number of female and male blood clams in each month of sampling was calculated and followed by the Chi square test to test the similarity. The results showed that the relationship between length and weight of A. granosa was positive allometric. The sex ratio of female and male blood clams in the waters of West Rangsang is not balanced. The number of male blood clams is more than the female.

Abstract

Global warming is caused by increased greenhouse gas emissions, particularly CO₂, and can be controlled through carbon sequestration by vegetation, including mangrove forests. The study was conducted in January and February 2025 in the mangrove area of Penempul Village, Sungai Sembilan District, Dumai City, Riau Province, to determine the density in relation to biomass, carbon stock, and CO₂ absorption, as well as to investigate the relationship between density and biomass, carbon stock, and CO₂ absorption. The method used in this study was a survey method with a purposive sampling technique, which involved measuring the diameter of mangrove tree trunks at chest height (DBH). Mangrove biomass calculations were performed using allometric equations, and biomass was converted into carbon stock and CO₂ absorption. The study results indicated the presence of 11 mangrove species, with average estimated biomass, carbon stock, and CO₂ absorption values of 521.84 tons/ha, 245.25 tons/ha, and 899.35 tons/ha, respectively. The ANOVA results showed significant differences (p > 0.05) between the three stations regarding biomass, carbon stock, and CO₂ absorption. Mangrove density had a weak correlation with biomass, carbon stock, and CO₂ absorption, with a correlation coefficient of 0.299.
