Abstract

Mangrove are coastal ecosystems that play a crucial role in maintaining environmental stability, protecting shorelines, and providing essential habitats for diverse species of flora and fauna. Mangrove ecosystems also play a vital role in mitigating climate change by absorbing and storing atmospheric carbon. This study was conducted with the objective of estimate the carbon stock in mangrove seedlings and sediments within the Essential Ecosystem Area (EEA) of Bagek Kembar, Sekotong, West Lombok. Mangrove seedlings sampling was conducted using the destructive (harvesting) method and analyzed in accordance with the Indonesia National Standard (SNI), while mangrove sediments sampling was carried out using a corer and analyzed using the Loss on Ignition (LOI) method. The results showed that natural mangroves had seedlings carbon stock of 3.44 tons C/ha, whereas rehabilitated mangroves had seedlings carbon stock of 2.95 tons C/ha. Carbon stock at sediment in natural mangroves was 591.49 Mg/ha, and for sediments at rehabilitated mangroves was 575.39 Mg/ha. The average seedlings carbon stock in the EEA Bagek Kembar Sekotong West Lombok was 3.19 tons C/ha, while the average sediments carbon stock was 583.41 Mg/ha. These findings highlight the significant carbon storage potential of mangroves ecosystems, particulary in seedlings and sediments. Although mangrove seedling possess relatively small biomass, they make a meaningful contribution to future carbon stock.

Abstract

Mangrove forests have various roles in the environment, and have the potential to be developed as ecotourism areas. The aim of this study is to identify the potential and suitability of the Bagek Kembar mangrove forest as a tourist attraction. Data collection was carried out at two stations, namely natural and rehabilitated mangroves. Samples were taken in plots measuring 10 x 10 meters for mangroves and mobile fauna, and 1 x 1 meter plots for sessile fauna. The Tourism Suitability Index is analyzed based on the number of species, density and thickness of mangroves, number of fauna species, and water depth at high and low tides. The research results show that the Bagek Kembar mangrove forest area is classified as suitable to very suitable for development as an ecotourism area. Tourist attractions that potential to be developed are educational, birdwatching and culinary.

Abstract

Orange-footed scrubfowl (Megapodius reidwardt) are protected species and need to be preserved. Orange-footed scrubfowl (Megapodius reidwardt) are terrestrial birds that build nests on the ground. To maintain its sustainability, it is necessary to have knowledge about the characteristics of orange-footed scrubfowl nests. Kerandangan Natural Tourism Park is one of the places where orange-footed scrubfowl are found, but until now there is still no information about the characteristics of orange-footed scrubfowl nests. So this study aims to analyze the characteristics of orange-footed scrubfowl nests in Kerandangan Natural Tourism Park. The method used in this research is descriptive exploration, the research variables include physical parameters of the nest, environmental parameters of the nest, chemical parameters of the nest mound and plant vegetation around the nest. The results showed that the diameter of the nest ranged from 400-590 cm with a nest height of 85-154 cm, the number of laying holes ranged from 1-3 holes and the soil texture class of the nest mound consisted of sandy loam and loam. Environmental parameters obtained average temperature outside the nest 27,9oC, average temperature inside the nest 28,6oC, average humidity outside the nest 80,3%, humidity inside the nest 81,2% and light intensity ranged from 98,1-834,1 lux in the morning, 437,8-4014,8 lux in the afternoon, and 45,7-653,8 lux in the afternoon. Chemical parameters obtained organic matter content ranged from 1,4%-3,2% and pH ranged from 6,8-7. Vegetation that had the highest INP in each nest was Voacanga foetida, Inga edulis, Artocarpus elasticus, and Bambusa bambos, these plant species act as materials for building nest mounds and potentially as food for orange-footed scrubfowl.
