<strong>Carbon Stock Estimation in Seagrass Biomass on Semak Daun Island, Thousand Islands</strong>. Seagrass ecosystem has a vital role in protecting the coastal ecosystem. It can also sequester and store carbon as an organic material (blue carbon) for a long time. However, anthropogenic activities in coastal areas give environmental stress on the seagrass ecosystem. This research was conducted to assess the carbon stock of seagrass biomass in Semak Daun Island in order to evaluate the potential of the seagrass meadows in sequestering carbon. Sampling and observation were held in the seagrass ecosystem to obtain seagrass density, biomass, frequency of occurrence, water quality, and anthropogenic activity. Carbon stock was calculated by the loss of ignition (LOI) method, and combined with density to determine the total carbon stock in the whole area of seagrass meadows. Seagrass species in Semak Daun Island consist of Halophila ovalis, Thalassia hemprichii, Cymodocea rotundata, Syringodium isoetifolium, and Halodule uninervis. The coverage area of seagrass in Semak Daun Island was 9.1 ha with carbon stock value of 1.84 ton C or equivalent to 6.76 ton CO2. Fifty two percent of the carbon stock was originated from the below-ground biomass and 48% from the above-ground biomass.
Marine tourism activities in small islands have an important role in the development of Indonesia maritime sector. This study aimed to estimate the economic value of marine tourism activities in Untung Jawa Island. Individual Travel Cost Method (ITCM) was selected to analyze the level of tourism demand of Untung Jawa. Samples were taken from three different season visits are weekday, weekend, and national holidays. The results showed the factors that have an effect on the level of tourist demand of Untung Jawa Island are travel cost, income, and distance to the location. The potential economic value of marine tourism Untung Jawa Island was IDR 68,505,101,600 with consumer surplus of IDR 397,592 per individual trip. This value is higher than the average of actual visitor expenditure which reached IDR 296,860 per individual trip. Tourism activity has a positive impact on economic conditions of local communities. The results of this study have provided useful information for sustainable management of marine resources.
The COVID-19 pandemic has impacted the seaweed industry and business. The export-import trade is the most severely impacted sector, mainly the raw material export of seaweed. The purpose of this study was to determine how smallholder farmers in West Nusa Tenggara, Indonesia, can survive under adverse conditions and maintain their businesses during a pandemic. The research was conducted through a combination of field surveys and in-depth interviews with respondents. Interviews were performed using a variety of instruments, including questionnaires and cameras. According to the study's findings, smallholder farmers are impacted by a decline in prices and demand. Smallholder farmers in West Nusa Tenggara, Indonesia, are attempting to adapt or adjust their operations to maintain profitability. Seaweed farmers make significant savings and cut their spending in the event of a pandemic. What is intriguing is that respondents did not reduce their spending on food. Instead, they prioritize reducing tertiary needs. Additionally, the same holder farmer borrows from collectors, borrows from the bank, and works side jobs. Thus, seaweed farmers are relatively unaffected by this pandemic and recover more quickly than other types of fishery businesses.Keywords: Covid 19, seaweed, smallholder farmer, Nusa Tenggara Barat
