Abstract

This study aims to determine the density of seagrass species, seagrass biomass, and threats faced by seagrass communities in the Coastal District of Lamongan. The study was conducted in August to November 2019 in three coastal villages of Lamongan Regency, namely Tunggul Village (Station 1), Kranji (Station 2), and Banjarwati (Station 3). The stages of the study consisted of: preparation, data collection on density, threat data and seagrass stand samples, sample processing, and data analysis. The results showed that the total density of seagrass species at Stations 1, 2 and 3 was 160 stands / m2; 172 stands / m2; and 185 stands / m2. Furthermore, the total biomass of seagrass at Stations 1, 2 and 3 was 4633 gbk / m2, 2136 gbk / m2, and 9234 gbk / m2. In addition to seagrass species, seagrass density values also affect seagrass biomass. As development progresses in Lamongan Regency, it is known that the biggest threat of seagrass communities in the study site is human activity (anthropogenic), among others: anchor ships when anchored and the use of coastal areas as tourist areas, which often cleans up seagrass communities because they are deemed unfit to be enjoyed tourism sector.

Abstract

Coral reef ecosystems are among the most productive natural biodiversity resources  in tropical coastal areas, within seagrass beds and mangrove forests. Besides, coral reefs have very high ecological impacts and economic value that are managed well and sustainably. Also, healthy ecosystems will undoubtedly provide more incredible benefits and values, so studies need to be conducted to determine the health of coral reefs. While P2O LIPI is an institution that is the guardian of coral reef health data in Indonesia, there is limited information related to the coastal areas of East Java that has not been widely reported. This study aimed to find out the percentage of living hard corals and the health status of the ecosystem at three reef sites: Banyuwangi, Situbondo, and Probolinggo. Field surveys were carried out in June-July 2019, using the Line Intercept Transect (LIT) method. The materials used in this study are Self-Contain Underwater Breath Apparatus-SCUBA diving equipment, roll meters, and an underwater camera. The results showed that the hard coral cover living in Banyuwangi accounted for 28.91%, Situbondo was 31.20%, and Probolinggo (34.77%). Therefore, this study interpreted that the coral reef ecosystem was a moderate category (25% - 49.9%).

Abstract

One of the tourist attractions at Bangsring Beach is the condition of the coral reef ecosystem and unique marine biota that tourists can enjoy by snorkeling and diving. Based on research (Ekawati et al., 2021) using remote sensing, the area of live coral reefs on Bangsring Beach is as follows; 2005; 3.38, 2008; 2.61, 2011; 3.7, 2017; 3.98, 2020; 6.1 Ha). It can be said that the area of coral reefs increases yearly, although, in 2008-2011, it decreased by 32%. The results of the economic valuation explain that the (Total Economic Value) of the coral reef ecosystem in Bangsring Beach is 38.2 billion Rupiah/year or 2.9 billion Rupiah hectares/year. The use-value that has the largest economic value comes from tourism utilization of 25 billion or 60% of the Total Economic Value. The coral community structure includes Coral Branching, Coral Encrusting, Coral Massive, Coral Submaasive, and Coral Mushroom. Mushroom Coral is found solitary and shaped like a mushroom. The research data shows the average value of Bangsring Fish House cover is 82.5%. Fish house cover here is seen and assessed based on the presence of hard corals, soft corals, and algae. The average percentage of hard corals growing at the Bangsring Fish House was 30%, soft corals 21.5%, and algae 17.5%. Found 21 types of coral such as; Acropora, Favia, Turbinaria, Symphyllia, Goniastrea.
