Abstract

Today's mangrove ecosystem is increasingly under pressure, mainly due to the conversion of mangrove land into aquaculture, tourism, and industrial areas. At the same time, the mangrove ecosystem has a very vital role in life. Efforts have been made to slow down the degradation rate of the mangrove ecosystem, including by replanting activities (reforestation). Mangrove planting activities are often constrained by the lack of healthy seeds or a mismatch between the seeds and the planting environment. It causes the planted mangrove seedlings not to be able to grow appropriately and even die. This community service activity aims to educate and assist the community in Poton Bako Hamlet, Jerowaru Village, Jerowaru District, East Lombok Regency regarding mangrove nursery techniques, especially R. mucronata and S. alba species, properly and correctly. The method used is using booklet media and direct practical assistance. Moreover, the community listens and practices what has been conveyed regarding nursery procedures. The results of this activity received high enthusiasm from the community, and the community felt its usefulness. This mentoring activity requires follow-up in the form of continuous control and assistance so that future nursery programs carried out independently by the community can continue and run optimally. In the future, it is hoped that the community's independence to carry out mangrove nurseries can run well. Thus what has been obtained by the community can be transmitted to others so that mangrove conservation is maintained.

Abstract

Cempi Bay is an important water area with a rich and diverse ecosystem. One crucial component of marine ecosystem that plays a major role in maintaining the balance of the marine environment is seagrass. The objective of this research is to provide critical insights into the dynamics of seagrass populations in Cempi Bay and offer an overview of the broader coastal ecosystem's condition. The research, conducted in June-July 2021 at 5 research stations, employed the transect method. At each data collection point, three transect lines were created perpendicular to the coastline. The distance between transect lines was 100 m, and each transect consisted of 10 quadrants measuring 1x1 m with a 5 m distance for each quadrant. Four seagrass species were identified: Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Cymodocea serrulata. These species were found on sand substrates, with the highest total density and percentage cover observed at Station 5 (1135.22 ind/m2 and 40.74%). The results highlight the necessity for routine monitoring, mapping, and further research to comprehend seagrass population dynamics and support effective conservation policies. Implementation of recovery strategies, water quality management, and continued research support is imperative to ensure the sustainability of seagrass ecosystems and marine resources in Cempi Bay.

Abstract

The mangrove ecosystem is a coastal ecosystem that is important for humans. Mangroves absorb carbon in the atmosphere and store it in biomass or sediment. So, in other words, mangroves play a significant role in mitigating global climate change. This study aimed to examine the structure of the mangrove ecosystem composition and estimate standing carbon stocks on Sangiang Island, Banten. The data taken was for the categories of trees, saplings, and seedlings (consisting of mangrove species, DBH, and height). The study was conducted at three stations with three replications for each station. The allometric formula obtained the estimated carbon stock from the stand biomass value. The results showed that 11 species of mangrove species were found with an average density of 1266 ind/ha (trees), 3733 ind/ha (saplings), and <70% (seedlings). Then the estimated average carbon stock in Sangiang Island, Banten is 271.29 tons/ha.
