Abstract

Mangrove ecosystems are a vital form of aquatic ecosystem that significantly contribute to maintaining carbon balance in the atmosphere and support climate change mitigation efforts. Their ability to absorb and store carbon in both biomass and soil makes them among the most effective carbon sinks. This study aims to estimate the carbon storage of mangrove stands in the Gita Nada Mangrove Area, Sekotong, West Lombok. The research was conducted at three stations: Station 1 (Berambang), Station 2 (Siung), and Station 3 (Bangko-Bangko). Data collection involved a 10 x 10 meter transect, where species and diameter at breast height (DBH) data were recorded. Allometric equations were then applied to calculate biomass and carbon reserve values. The results identified four mangrove species: Rhizophora mucronata, R. stylosa, R. apiculata, and Avicennia marina. The average mangrove density at each station fell within the moderate to dense category, with values ranging from 1000 to 4666.66 individuals per hectare. The estimated carbon stocks of the mangrove stands were as follows: Station 1 had 149.33 tons per hectare, Station 2 had 28.38 tons per hectare, and Station 3 had 476.36 tons per hectare. These findings indicate significant differences in estimated carbon stock values across the stations. Overall, the results of this study provide crucial information to support conservation and restoration efforts for mangrove ecosystems in West Lombok, enhancing understanding of the role of mangroves in mitigating climate change.

Abstract

Sea stars have morphological characteristics that are radially symmetrical, have 5 (five) or more arms, do not have a skeleton and move freely using tube legs. Sea stars not only function as litter cleaners in the waters, but are also utilized as food processing and handicraft materials. The study aimed to determine the diversity and abundance of sea star species in the coastal area of Pandanan Hamlet, West Sekotong, West Lombok Regency. This study used the belt transect method. All starfish found in the transect recorded the type, number, and habitat characteristics. The results found 6 species of starfish from 4 families namely Echinasteridae, Archasteridae, Ophidiasteridae, and Oreasteridae. The six species are Henricia sp., Archaster typicus, Linckia laevigata, Culcita sp., and Pentaceraster sp. The diversity index (H') has a value of 0.3 - 1.7, the uniformity index (E) is 0.5 - 0.9, and the dominance index (C) ranges from 0.2 - 0.8. The highest abundance in the species Linckia laevigata with a value of 571 ind/ha (station 1) and 333 ind/ha (station 1), while the lowest abundance in the species Pentaceraster sp. 33 ind/ha. All starfish were found to be associated with seagrass plants except Pentaceraster sp.
