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

Mantis shrimp is one of the marine organisms that has a very abundant diversity of species. The similarity of morphology of this group make it difficult to identify morphologically. Therefore, identification was carried out using a DNA barcoding approach. The purpose of this study was to identify the mantis shrimp species from Manokwari waters using molecular techniques. The CO1 gene fragments were amplified by using LCO and HCO primers. The DNA sequences obtained were analyzed for homology, phylogeny, and genetic distance using MEGA X software. A total of 537 base pairs of CO1 gene fragments of mantis shrimp from Manokwari were obtained. The results of the homology analysis on GenBank, show the highest similarity of 91.18% with sequences from the genus Gonodactylus. Analysis of phylogenetic tree and genetic distance showed the same results and supported each other with homology analysis on GenBank data.

Abstract

Mangrove forest is a permanent habitat and transit area for various fauna. In the mangrove community, it forms a mixed habitat between terrestrial and aquatic fauna groups. This study aims to analyze the composition of mangrove species and the abundance of insects. There are 3 research station on the mangrove forest ecosystem on Payum beach. Sampling was carried out using the Line Transect method, starting with making a line transect (50 meters) on the outermost mangrove stands and pulling them inland. On each transect line a plot measuring 10 x 10 m is placed, in each of which 5 subplots/quadrants measuring 1 x 1 m are placed. Each transect line consist of 3 plots and 15 sub-plots will be obtained, so there are a total of 45 sub-plots. Based on the research results, it was found that several types of macrobenthos live abundantly and are associated with mangrove ecosystems, such as Terebralia palustris, Terebralia semistriata, Nerita sp., Cassidula angulifera, Cerithidea sp., Telescopium telescopium. Four species of mangroves are found on Payum Beach, Merauke Regency, South Papua Province, namely Avicennia alba, Rhizophora apiculate, Sonneratia alba, and Aegialitis annulata. The insect diversity index in the mangrove forest on Payum Beach in Merauke is H'=2.61, which indicates that the environmental conditions of Payum Beach are still quite good and insect diversity is in the medium category. The evenness index of 0.42 is included in the medium category because human activities vary, and the dominance index is 0.63 because the Payum Beach mangrove forest has various types of insects with moderate dominance.

Abstract

This study aims to determine the growth pattern of barbfish, the condition factors of barbfish, and the water parameters (temperature, brightness, pH, and salinity) in the Maro River waters. This research was conducted in April – June 2024 using the Purposive sampling method. The results of the study showed  (1) The growth pattern of male and female barbfish at each station shows a positive allometric growth pattern, which means that the increase in fish weight is faster than the increase in fish length. (2) The highest condition factor (FK) value was in the female barbfish caught at station 2 with an average value of 1.0074, the next highest (FK) value was in the male barbfish caught at station 2 with an average value of 1.0013 and the lowest (FK) value was in the male barbfish caught at station 1 with an average value of 0.9885. (3) The results of water quality measurements in the Maro River show that the temperature ranges from 27 – 30oC, clarity 30 – 35 cm, pH ranges from 7.2 – 7.5, and salinity ranges from 25 o\oo – 29 o\oo. Overall, the results show that it still supports the existence of marine biota and has not experienced pollution with a stable category and by the quality standards set by Government Regulation Number 22 of 2021 on Implementation of Environmental Protection and Management.
