Abstract

Mount Geulis University Forest (MGUF) is a university forest area surrounded by eight villages and has close relationships with the surrounding community. With a very strategic position, MGUF is vulnerable to various pressures, especially anthropogenic ones. Other studies have shown that population, development, and the economy have an essential role in environmental degradation. Thus, understanding these three things becomes essential to determine the right strategy to reduce the level of vulnerability around MGUF. This study aims to analyze the level of community dependency on MGUF and the level of vulnerability of the community around MGUF. Community dependency was analyzed using perceived value dependency on livelihood, perceived value dependency on income, and perceived value dependency on participation level. Community vulnerability was analyzed based on the population growth index, built-up land index, and economic openness index. The results showed that the farmer community had a relatively high dependency on MGUF. The lower the income, the higher the dependency on MGUF, and the participation rate increases as the dependency on MGUF increases. Raharja Village has the highest population growth index of 123.75, Mangunarga Village has the highest built-up land index with a value of 75.11, and Jatimukti Village has the highest economic openness index with a value of 33.52. In general, the village with the highest composite vulnerability index is Cikahuripan Village, with a value of 0.71, and the lowest is Jatiroke, with a value of 0.20. Based on the value of the vulnerability index and the level of security, the level of vulnerability can be reduced by carrying out collaborative management to run programs with every stakeholder in the MGUF management system.

Abstract. Erniasari I, Hernawan E, Mulyaningrum. 2024. Short Communication: Carbon stock of mangrove forest in Pantai Sederhana, Bekasi District, West Java, Indonesia. Biodiversitas 25: 2974-2980. Mangrove forests play an important role in the carbon cycle because this forest can store greater amounts of carbon than other ecosystems including tropical rainforests. Mangrove forests in Bekasi District, West Java, Indonesia have enormous potential to absorb carbon in this industrial area. In this research, we estimate the aboveground carbon (AGC), belowground carbon (BGC), and soil organic carbon (SOC) of mangrove forest in Pantai Sederhana, Muaragembong Subdistrict, Bekasi District. Carbon estimation of AGC and BGC was carried out using the allometric method, while SOC at four depth intervals (0-15, 15-30, 30-50, and 50-100 cm) was estimated using the LOI (Loss of Ignition) method. There were four mangrove species in Pantai Sederhana, namely Avicennia marina, Avicennia alba, Rhizophora apiculata, and Rhizophora mucronata. The total carbon stock was 329.54 Mg.C.ha-1, which was composed by aboveground carbon (114.51 Mg.C.ha-1), belowground carbon (61.46 Mg.C.ha-1) and soil carbon (153.56 Mg.C.ha-1). The largest carbon pool was contributed from soils with 47% of the total carbon stock. The result of this study can be used as the initial information of the importance of the mangrove ecosystem in Bekasi District.
