Abstract

Mangroves are plants that live in tidal or interface areas between terrestrial and marine ecosystems in tropical and subtropical regions. Mangrove ecosystem is one of the coastal ecosystems that have a very important role, especially for organisms, namely as a supplier of nutrients produced by mangrove litter. An observation regarding litter productivity is still limited in Papua, especially in the city of Merauke. The method used in this study is the transect method, using 3 (three) transects. Mangrove litter is taken by using a litter trap container placed under the mangrove tree. The results obtained from litter production in each transect are as follows transect 1 of 167.8 g/m²/Month, Transect 2 of 65.4 g/m²/Month, and Transect 60 g/m²/Month while density mangrove in each transect 1 transect has a higher tree density value of 65 Ind/ m² while in Transect 2 it has a total litter production of 32 Ind / m² and the mangrove density value in Transect 3 is lower compared to stations 1 and 2 which are 25 Ind/m².

Abstract

Environmental degradation and the utilization of excess are very influential in a reduction of thepotential of Turbinidae Gastropod Resources. Morphology of shells can changes due to adaptation tothe surrounding environment resulting in misidentification. This study aims to analyze morphology andmolecular character of Turbinidae. Morphometric analysis is done by comparing the measureddimensions of the shell, while the molecular identification is done by using the DNA barcoding usingCOI gene to species identification. The results showed a comparison of growth between thedimensions shell of the Lunella sp. showed the negative allometric and positive allometric. Characterof shell growth between dimensions of the Lunella sp. shows the negative allometric and positiveallometric. Molecular analysis identified Turbinidae was found Lunella sp. its similar to DNAsequence Lunella sp. Sulawesi. The molecular analysis identifies Turbinidae found is Lunella sp. withsimilarities of 98.41 and 98.31%. The environmental conditions can affect change the morphology andgenetic of Turbinidae. DNA barcoding has been successful to identify Turbinidae gastropods.

Abstract

This study aimed to analyze the growth and reproductive patterns of the mudskipper (Boleophthalmus boddarti) in the Maro River area, Semangga District, Merauke Regency. The study was conducted in the Maro River area, Semangga District, Merauke Regency, from August to October 2024. Sampling was carried out twice per month using a purposive sampling technique. Quantitative data analysis was applied to evaluate growth patterns and reproductive characteristics, including sex ratio and gonadal maturity stage (GMS), of the mudskipper (Boleophthalmus boddarti). The results showed that a total of 56 mudskippers were collected during the study, consisting of 20 males and 36 females. The growth pattern analysis yielded the equation W = 0.0018L3.5138 in Sidomulyo Village and W = 0.0015L3.5831 in Urumb Village, indicating a positive allometric growth pattern. In terms of reproduction, the sex ratio of the mudskipper population remained relatively balanced. Regarding gonadal maturity stage, males were found only at GMS I, whereas females were recorded at GMS I and GMS II.

Abstract

The abundant potential resources in coastal and marine areas have the potential to be overutilized, which can lead to resource degradation. There are various management aimed at ecosystem sustainability, one of which is community-based ecosystem management. The purpose of this research is to provide information related to the role of community-based management that has been carried out. The method used in this research is the literature review method which is primary and secondary data that has been obtained from searching scientific articles and then compiled, analyzed and conclusions will be drawn. Community Based Management as a process of giving authority, responsibility, and opportunities to the community to manage its own resources preceded by determining needs and goals and aspirations. Various challenges are often experienced in management between the government, the community and also investors related to the use of space. Improving human resources in the form of education, training, access to technology and information, and institutional strengthening are needed to ensure that communities have the ability to manage their territory, while the government plays a role in maintaining, supporting and preserving existing culture or customs. The conclusion of this research is that the naming of each region is different but has the same goal, namely to maintain the sustainability of resources, so it is necessary to involve various parties in maintaining and documenting community-based resource management in each region.
