Abstract

The environmental services of mangrove forests as carbon sinks are one of the indirect benefits of the mangrove ecosystem. The absorption of carbon is carried out by mangrove vegetation through the process of photosynthesis. In this study, mangrove environmental services as carbon sinks are based on the ability to absorb CO2 expressed in carbon units (tC, tCO2), and the economic value of carbon storage in monetary units (Rp). This research was conducted in the Bagek Kembar Mangrove Ecotourism Area, Sekotong District, West Lombok Regency. The method used to take samples is stratified random sampling, where the placement of the plots is determined randomly. The observation plots for each type of growth are arranged in stages with different sizes. The plots are 10 m x 10 m for trees, 5 x 5 m for seedlings, and 2 x 2 m for seedlings. Trees are mangroves with trunk diameter > 4 cm, tillers have a stem diameter of 4 cm and, a height of > 1 m, and seedlings are mangroves with a height of < 1 m. This research shows that the mangrove vegetation in the research location has absorbed 6,437.80 tonnes of CO2eq, and a monetary value of Rp. 482.834.700 (four hundred eighty-two million eight hundred and thirty-four thousand and seven hundred rupiahs).

Abstract

Aquatic biodiversity in Muara Putat Estuary, Lombok Utara Regency, Lombok Island is the result of nutrient enrichment in the coastal. A complex combination of natural factors that support the growth of barriers in mangrove plants, agricultural and plantations, fish and aquatic invertebrates that regulate during the summer and rainy seasons. As a source of knowledge, biodiversity of aquatic microalgae is a major producer of nutrient chains in the estuary, habitat diversity will affect the source and regulation of aquatic nutrition. Studying microalgae is one of the important tools to determine the condition of an estuary and microalgae bioprospecting in the future. This study aims to determine the prospect of microalgae species found in Muara Putat waters during the summer and rainy season as well as to record the types of local microalgae found in these waters. Water samples are collected at 3 stations covering upstream, middle, and downstream estuary. Measures were carried out on the value of environmental supporting factors such as pH, water temperature, salinity, brightness, and currents. Obtained two local species that dominated the Bacillariophyceae and Chlorophyceae classes, with both of bioprospects that were sufficiently able to act as bio-indicators of aquatic saprobity, biochemical characteristics with various contents, could be as an agent of the Controlled Ecological Life Support System (CELSS), and produces certain metabolites based on changes in aquatic nutrient concentrations.
