Abstract

Mangrove ecosystems provide high biodiversity because, in addition to being inhabited by various types of vegetation, another role is to provide important areas used by various fauna species for spawning, nurturing, and feeding. This scientific article is a literature review. The data obtained is then analyzed and presented descriptively. The sources of data are reliable scientific references and various relevant sources of information including direct visual observations. The results of the study show that mangrove vegetation found in the Lantebung Mangrove Ecosystem is six species namely Rhizopora mucronata, Rhizopora apiculata, Bruguiera gymnorhiza, Avicennia marina, Avicennia alba, and Sonneratia alba. The mangrove fauna consists of classes of aves, Pisces, reptiles, crustaceans, Insecta as well as several species of gastropods, other macrozoobenthos, and phytoplankton. The Lantebung Mangrove Ecosystem has the potential to provide more biodiversity if mangrove management is carried out comprehensively.

Abstract

Mangroves have various roles for human life, one of which is as an alternative food ingredient, namely coffee raw material. Mangrove propagules, especially the fruit, can be processed and produce powders that can be brewed like coffee in general so this study aims to analyze the characteristics of mangrove fruit powder by calculating ash content, water content, caffeine, followed by sensory and hedonic testing of Rhizophora sp. This study used a laboratory-scale quantitative method followed by panelists' assessment of two different samples. Sample one is Rhizophora sp. mangrove fruit powder, while sample two is a mixture of Rhizophora sp. mangrove fruit powder with the addition of Arabica coffee beans. The test results of ash content, moisture content, caffeine, sensory, and hedonic testing respectively showed values of 2.48 and 1.49; 2.94 and 3.03; 1.36 and 0.92; 23.3 and 25.1; and 27.1 and 28.3. So it can be concluded that the water content and ash content of mangrove fruit powder with the addition of arabica coffee beans are higher than mangrove fruit powder. Although the caffeine content of mangrove fruit powder is higher than those that get additional arabica coffee. Mangrove fruit powder with the addition of Arabica coffee beans has a higher value in sensory and hedonic testing, panellists prefer and feel more satisfied when consuming mangrove fruit powder with the addition of Arabica coffee.

This research aims to show mangrove density in various conditions, to reveal the structure of the gastropod community. and the influence of hydrooceanography. This research was analyzed using the Shannon Wiener index variation method and The Principle Component Analysis (PCA). Overall research findings show: 1) mangrove density values at three station points, namely: a) station 1 (0.35); b) station 2; and c) station 3 (0.16); 2) gastropod density values, namely: a) station 1 (3.44); b) station 2 (3.00); c) station 3 (2.81). The highest relative and absolute frequency value of all stations is Littorina Scabra and the lowest is Terrebralia Pallustris. The diversity index value for gastropod species at various stations ranges from 1.00 to 1.45 and the unity index value ranges from 0.25 to 0.31, which is still relatively low. The distribution pattern of gastropods classified as community groups at each station ranged between 2.53-8.53. The results of the Principle Component Analysis show that gastropods at each station are influenced by environmental factors (Hydro Oceanography).

Abstract

This study aims to determine the effect of differences in salinity on the level of osmoregulation of vaname shrimp larvae (L. vannamei). The research method used a completely randomized design with 4 treatments and 3 replications, namely treatment 17 ppt (A), 22 ppt (B), 27 ppt (C), and 32 ppt (D). The parameters observed were survival rate, absolute weight growth, and osmoregulation at the osmotic work rate (TKO) of vaname shrimp. Data analysis used descriptive. A salinity of 22 ppt gave the best results for survival rates, namely 92.22%, and the best absolute weight growth results, namely 1.03 grams at a salinity of 17 ppt. The results showed that differences in salinity had no significant effect (p > 0.05) on survival and growth in absolute weight. The TKO value of treatment A is media with a salinity of 17 ppt with a value of 654 mOsm/H2O which is the highest TKO value and is a shrimp that is hyperosmotic, namely a liquid whose osmotic concentration is higher than its environment, treatment B is a medium with a salinity of 22 ppt with a value of 500 mOsm/H2O which is the lowest TKO value and is a shrimp that includes isoosmotic regulation. The level of osmoregulation in vaname shrimp indicates a stagnant osmotic performance level so it can be stated that there is no difference in TKO based on salinity.

Abstract

Preserving the mangrove ecosystem is very important for carrying out sustainable ecosystem management because the level of competition for eco-tourism in the mangrove ecosystem is increasing. An ecotourism can win the competition if it has a competitive advantage compared to its competitors. This idea of ​​competitive advantage comes from a resource-based perspective. We must have certain criteria so that the resource can be considered a strength or weakness. Therefore, the research method used is Mixed Method Research with the research aim of identifying Lantebung mangrove ecotourism resources, analyzing VR studies, and Lantebung mangrove ecotourism sustainability strategies. This research was conducted by placing resources and capabilities into five VRIOL categories. VRIOL is a tool for determining the nature of resources and capabilities. Meanwhile, the data collection technique is interviews and distributing questionnaires to 200 respondents using a sampling technique, namely purposive sampling. Furthermore, the data analysis technique used in this research is data triangulation. The research results show that VRIO analysis is used as a basis for identifying competencies possessed. To achieve a sustainable competitive advantage, these resources and capabilities must have four important attributes, namely valuable, rare, inimitable, and organized. This type of research is descriptive and qualitative research, data is collected using observation and interview methods. The research results show that there are sixteen types of resources in the Lantebung Mangrove Ecotourism consisting of tangible, intangible, and capability resources. Lantebung Mangrove Ecotourism has strategic strengths in sixteen resources at the Sustainable Competitive Advantage level.
