Abstract

Seagrass is one of the marine resources that considerably potential as a CO2 absorbent and functioned as carbon sinks in the oceans known as blue carbon. The result of carbon sequestration from the process of photosynthesis is stored as carbon stocks on seagrass tissue, or streamed to multiple compartments, such as sediment, herbivores and other ecosystems. This study aims to assess the potential for carbon stock storage in biomass on a tissue of seagrass in Sanur Beach coastal area. The observations of seagrass are included the seagrass type, seagrass stands, and measurement of environmental parameters. Then the sampling was conducted to obtain the value of seagrass biomass. The carbon stocks obtained through the conversion of biomass by using carbon concentration analysis of seagrass tissue and then carried a spatial distribution of carbon stocks. Types of seagrass found in Sanur Beach coastal area consist of eight species that are Enhalus acroides, Thalassia hemprichii, Halophila ovalis, Syringodium isoetifolium, Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis and Halodule pinifolia. The result of the carbon stock seagrass in the bottom substrate is 60% greater than the carbon stock in the top substrate which is 40%. Seagrass covering 322 ha of Sanur Beach coastal area with a total potential carbon storage of 66.60 tons or 0.21 tons / ha. Seagrass key role as a carbon storage is on the bottom substrate tissue, and Enhalus acroides is a seagrass species that contributes the most to the carbon storage.

Abstract

Coastal ecosystem is a productive ecosystem and has high ecological and economic value. Coastal ecosystem components, consist of coral reefs, seagrass beds, mangroves and various types of biota. The seagrass ecosystem is one of the most unique coastal ecosystems because the seagrass can live well in high salinity conditions. Seagrass ecosystem in Bali Island has many adventages and widely used for marine tourism activities. One of the marine tourism sites, that take advantage of the beauty of the seagrass ecosystem in Bali is Sanur beach. The utilization of seagrass ecosystem for marine tourism activities might be influence the structure of seagrass community. Therefore, the study about Community Structure of Seagrass Ecosystem at Intertidal Area in Sanur Beach is very important to carried out in order to investigate the structure of the seagrass ecosystem community. Samples were taken in the intertidal zone at six observation stations. At each station, it was conducted three times perpendicular repetition to the shoreline. Seagrass observation was done by using quadratic transect (50 × 50 cm). The types of seagrass found in Sanur Beach were 6 species, namely Cymodocea serrulata, Cymodocea rotundata, Halophila ovalis, Halodule uninervis, Halodule pinifolia, and Syringodium isoetifolium. Cymodocea serrulata is a seagrass-type found in every observation station, and it able to live well in Sanur Beach water characteristics. The highest average of seagrass species density is shown by the Cymodocea serrulata species of 175.11 stands/m2, while, the highest average of seagrass species density is shown by the Halodule pinifolia species of 27.33 stands/m2. The average of diversity, uniformity and dominance index at Sanur Beach reach 0.8682; 0.7347; and 0.4987, respectively. In Sanur Beach area, the seagrass has high uniformity value and stable community. The instability community has been found at station 2 when the dominance of Cymodocea serrulata species was occurred.

Abstract

Telagawaja Sub-Watershed is upper part watershed of Unda Watershed. As upper watershed, Telagawaja sub watershed has functions as conservation area, water catchment area, and managed in order to keep sub watershed environment not degradated. This research objectives are to identify the characteristics of the land, the function of the area, and the erosion potential rate (TBE), as well as land management recommendations on Telagawaja Sub-Watershed. The identification of land is conducted by analyzing the characteristics of thematic maps in study area. The directives of classification land function is determined by the Minister of Agriculture Number.837/Kpts/Um/ 11/1980 and Number: 683/Kpts/Um/8/1981. The prediction of actual erosion is calculated by USLE formula for the agriculture area, while non-agricultural land use is applied Snyder formula (1980) in Asdak (2010). Erosion class and erosion rate (TBE) are determined based on the Director General of Reforestation and Land Rehabilitation Department of Forestry Number.041/Kpts/V/1998. Determination for the amount of erosion is still can be allowed using the method of Thompson (1957) in Arsyad (2010) which based on soil properties attached to Telagawaja sub watershed. The research shows that Telagawaja Sub-Watershed characteristic is an area which is susceptible to erosion.The analysis shows that the direction of the area function Telagawaja sub-watershed consists of an area of 7337.28 Ha of protection forest (66.01%), and the function of a buffer area 3.778.31 Ha (33.99%). The result of the study on Telagawaja sub-watershed erosion is 2777.07 tonnes ha-1year-1. Erosion class and erosion rate of Telagawaja Sub-Watershed vary from very light to very severe. Erosion class and erosion rate (TBE) with category severe to very severe consist an area of 2.071,97 ha (18,64 %) from total sub-watershed area. Land use planning implemented by applying alternative measures of soil and water conservation can reduce the rate of erosion of 2777.07 tonnes ha-1year-1 to 611.00 tonnes ha-1year-1 or less 2166.07 tonnes ha- 1year-1.
