“…This is following the opinion of Harimbi et al 10 , the biomass value will be directly proportional to the density value so that the density affects the biomass. This is confirmed by the opinion of Heriyanto et al 11 , which states that the high value of seagrass biomass is in line with the high value of seagrass vegetation density.…”

This research was conducted in January 2022. Seagrass density calculations and seagrass sampling were carried out in Dusun Jati, Tuapejat, Sipora Utara District, Mentawai Islands Regency, and seagrass sample analysis was carried out at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, Universitas Riau. The objective of the study is to analyze the density of seagrass C. rotundata, analyze the biomass and carbon stock stored in Agb and Bgb parts, and whether there are differences in density, biomass, and carbon stock between stations in seagrass C. rotundata at the research site. The density value of seagrass C.rotundata varies for each station. The average density of seagrass C. rotundata at the study site was 33.48 stands/m2. The range of the biomass value in the Agb section is 21.78-39.9 gbk/m2 while the Bgb section is 31.01-61.4 gbk/m2. The average value of the carbon stock stored in the Agb section is around 2.08-5.34 gC/m2 and the Bgb section is 10.81-15.48 gC/m2. The conclusion from this research is that the density of seagrass at the research location is infrequently and each station has a different density. The highest biomass is found at a greater density as well as the carbon stock. Biomass between stations was not significantly different while the Agb and Bgb parts were significantly different. Density, biomass, and carbon stock have a very strong relationship.

“…The existence of coastal communities has interaction with mangrove ecosystem, for example, the utilization of wood extracted from mangrove for building materials (Hendrawan et al 2018). Since most mangrove areas are under the authority of government (which are often considered open access by some people) and they are located in a sandy coastal area around the estuary which is easily accessible by humans, mangrove forests are prone to be exploited and disturbed (Heriyanto et al 2020). Various anthropogenic activities that threaten mangroves in Indonesia are detailed below.…”

Abstract. Cahyaningsih AP, Deanova AK, Pristiawati CM, Ulumuddin YI, Kusumawati L, Setyawan AD. 2022. Review: Causes and impacts of anthropogenic activities on mangrove deforestation and degradation in Indonesia. Intl J Bonorowo Wetlands 12: 12-22. Indonesia is a country with the largest extent of mangroves in the world. However, as the human population increases, the extent and quality of the mangroves decrease. The increasing population is in line with the increase in human activities, leading to deforestation and degradation of the mangrove forests. This paper aimed to review anthropogenic activities that cause mangrove deforestation and degradation in Indonesia and the impacts of such anthropogenic activities on the mangrove ecosystems and formulate the efforts to overcome mangrove deforestation and degradation in the country. Various human activities are the primary drivers of deforestation and degradation of mangroves, including land conversion from mangrove forests into other land uses (e.g., agricultural lands, ponds, infrastructure developments, and human settlements), extractive activities (e.g., mining and logging), and household and industrial activities (e.g., plastic debris, heavy metals pollutants). These anthropogenic factors reduce mangrove forest area, changes in mangrove composition, uneven species abundance, and pollution. Combined with sea-level rise caused by global climate changes, such activities pose devastating threats to Indonesian mangroves. Efforts to overcome these problems include increasing awareness of communities regarding mangrove conservation, conducting mangrove restoration programs, and promoting sustainable management of mangrove, for example, through ecotourism. On top of that, community participation plays an essential role in Indonesia's sustainable management and conservation of mangrove forests.

“…Mangroves in Indonesia are generally under the authority of the government, where in the view of the community, mangroves are open access, so in conditions of easy access, mangroves will be used uncontrollably. This makes mangroves vulnerable to degradation [14]. Over-exploitation that causes mangrove degradation in the study locations also occurs in other areas in Indonesia.…”

Data and information on resource utilization supported by vegetation mapping is the basis for developing a sustainable mangrove management strategy. This study aims to map the density of vegetation and identify the use of mangroves by the community in the Klawalu Mangrove Tourism Park (Taman Wisata Mangrove Klawalu-TWMK) Sorong City. The satellite imagery used is Sentinel 2A level 1C. Image pre-processing includes atmospheric correction, geometric correction and image cropping. Determination of the extent and distribution of mangrove vegetation is carried out by applying the color composite method and mangrove boundary delineation. Mangrove vegetation density mapping was carried out by applying the Normalized Difference Vegetation Index (NDVI) method. Identification of the species and intensity of mangrove utilization was carried out through observation and interviews with respondents who were determined purposively. Based on the results of the analysis, the total area of mangrove vegetation in TWMK and its surroundings which is mapped is 144.64 ha. Of this area, 69.01 ha (47.71%) is classified as very dense, 34.96 ha (24.17%) is classified as dense and 24.23 ha (16.75%) is classified as moderate, 12. 94 ha (8.95%) is classified as sparse, and 3.5 ha (2.42%) is classified as very sparse. The intensity of resource utilization from the mangrove ecosystem is quite high, especially the utilization of mangrove wood and coral mining. Awareness/education efforts need to be continued, as well as alternative livelihood solutions to reduce the heavy dependence on mangrove resources.
