Potential Absorption Carbon Stock of Mangrove in Teluk Awur and Tanggul Tlare, Jepara Regency

Abstract

Mangroves are one of the ecosystems that play an essential role in mitigating climate change by storing and absorbing CO2. One of the mangrove areas that can be found in Jepara Regency in Teluk Awur and Tanggul Tlare. Both of these areas is experiencing coastal abrasion, which impacts the land and mangrove areas. The reduced area of mangroves affects the ability of the ecosystem to store and absorb CO2. This study intends to determine the potential for CO2 absorption in above-ground, below-ground, and mangrove sediments. The method used in determining the station point is the purposive sampling method. While the analysis of the calculation of standing carbon storage uses allometric equations in sediments using the LOI method (Loss on Ignition). The potential for carbon absorption above-ground station 1 is 75.12 Ton.ha-1, below-ground is 51.48 Ton.ha-1, and sediment is 286.49 Ton.ha-1. While the potential for CO2 absorption at station 2 consists of 28.27 Ton.ha-1 above ground, 19.86 Ton.ha-1 underground, and 243.73 Ton.ha-1 of sediment. Based on the study’s results, the potential for CO2 absorption in the mangrove area in Teluk Awur can store more carbon than in the Tanggul Tlare mangrove area, this is supported by the diameter of the mangrove stems in Teluk Awur which has a higher size.
