Abstract

Penelitian telah dilaksanakan pada Agustus 2017. Lokasi penelitian Pulau Pannikiang Kabupaten Barru. Tujuan untuk mengetahui perbedaan kandungan bahan organik disetiap jenis mangrove dan hubungan kerapatan dan penutupan jenis mangrove dengan kandungan bahan organik di sedimen. Pengambilan data mangrove dan sampel bahan organik berdasarkan jenis mangrove dominan di pulau pannikiang. Pengambilan data dengan menggunakan metode transek (Line transect) dengan luas plot 10 x 10 meter pada ke tiga stasiun. Hasil penelitian menunjukkan bahwa pada jenis mangrove dominan dan tumbuh berkelompok antar jenis mangrove di pulau Pannikiang tidak berbeda kandungan bahan organiknya sedangkan stasiun jenis mangrove dengan stasiun yang tidak ditumbuhi mangrove berbeda kandungan bahan organiknya. Hal ini dikarenakan bahwa keberadaan bahan organik dipengaruhi oleh kerapatan dan penutupan jenis mangrove. Hasil pengukuran kerapatan di setiap jenis mangrove tergolong dalam kategori sedang yang berkisar antara 0,06 – 0,12 (individu/m2). Kandungan bahan organik tertinggi pada stasiun 1 jenis mangrove Rhizophora apiculata adalah 32,83% dan stasiun 3 Rhizophora stylosa 30,57%. Hubungan kerapatan jenis mangrove dengan kandungan bahan organik menggunakan analisis linear diperoleh nilai koefisien determinasi (R2) sebesar 0,353, sedangkan nilai koefisien korelasi diperoleh sebesar 0,594 yang berarti berkorelasi positif antara kandungan bahan organik dengan kerapatan jenis mangrove. Kata kunci: Ekosistem Mangrove, Jenis Sedimen dan Kandungan Bahan Organik di Pulau Pannikiang

Abstract

ABSTRACT - Phytoplankton are plants of very small size, their life hovering in waters. Changes in the abundance of types and also the structure of their communities, can be explained by the analysis of the Redfield Ratio. The Redfield ratio is defined as a comparison of the content of N and P types of nutrients in a body of water. For this reason, the purpose of this study is to analyze the Ratio of Redfield to the suitability of phytoplankton life in the Lantebung mangrove ecosystem in Makassar City. The results showed that as many as 19 phytoplankton genera classified into 3 classes were found, namely the Bacillariophyceae class consisting of 14 genera, Cyanophyceae 1 genus, and Dinophyceae 4 genera. The genus of phytoplankton found at all stations is Rhizosolenia and Chaetoceros. These two types of phytoplankton are the Bacillariophyceae group. The results of the Redfield Ratio analysis are not optimal for phytoplankton growth, the ratio is below 16 Based on this, the redfield ratio is not in accordance with phytoplankton life in the Lantebung mangrove ecosystem in Makassar City. The results of pearson's correlation analysis between Redfield Ratio and phytoplankton abundance were 50.7 %. Keywords: Redfield ratio, phytoplankton abundance, Lantebung, Makassar City.

Abstract

Background: Marine debris refers to all solid materials resulting from human activities that are found in aquatic environments, such as oceans, seas, and coastal areas. These materials directly threaten aquatic ecosystems' health and productivity and require specific actions to prevent and mitigate their negative impacts. In mangrove ecosystems, the density of mangrove vegetation may influence the accumulation of marine debris. This study investigates the relationship between mangrove density and the abundance and types of marine debris around Kassikebo Pier, Pangkep Regency. Methods: The research employed the parallel line method for sampling marine debris and a 10 m x 10 m transect for assessing mangrove density. The study was conducted across three stations with varying mangrove densities: sparse, medium, and dense. The abundance and percentage mass of debris were calculated based on size and type. Physical oceanographic parameters were also measured, such as current direction, velocity, and tidal patterns. The mangrove species were identified, and their densities were analyzed to determine their correlation with marine debris abundance. Findings: The study revealed that macro-sized debris dominated across all stations. At Station 1 (sparse mangrove density), the abundance of macro debris was 0.45 pieces/m² and 7.97 grams/m²; at Station 2 (medium density), it was 0.66 pieces/m² and 14.75 grams/m²; and at Station 3 (dense mangrove density), it was 1.05 pieces/m² and 21.48 grams/m². Plastic was the most dominant type of debris at all stations. The mangrove species identified in the area included Avicennia alba, Avicennia marina, and Rhizophora mucronata, with Avicennia alba being the most abundant. Conclusions: The study found a positive correlation between mangrove density and the abundance of marine debris, indicating that denser mangroves tend to trap more debris. Novelty/originality of this article: his research highlights the link between mangrove density and marine debris accumulation, stressing the need for plastic waste management in mangrove-rich areas. It offers recommendations for local governments and communities to adopt the 3R approach.

Abstract

Mangrove forest ecosystem is one of coastal ecosystem having significant roles as habitat for diverse organisms, as barrier ofseawater intrusion, sediment trap, protection to the shore from abrasion and as nutrient supplier in form of detritus to othercoastal ecosystems i.e. seagrass beds and coral reefs. However, mangrove has experienced degradation caused by natural andanthropogenic factors. One effort to recover the mangrove’s function is by rehabilitating this ecosystem through controllingits total organic matter and the soil acidity (pH). Therefore, it is urgent to conduct a study in order to know the relationshipbetween mangrove growth and the total organic matter and pH. The study was conducted May 2014. The study area was locatedin Mampie, Wonomulyo Sub-District, Polewali Mandar Regency. The benefit gained from this study was giving information ondissolved organic matter related to the mangrove rehabilitation. Method used was field survey by determining three observationstations with different environmental condition. Data were presented as tables and pictures. Results of this study indicated thatincreasing of mangrove density and coverage was followed by the increasing of total organic matter percentage within sedimentat station II. Whereas, the higher the acidity, the lower the content of the total organic matter within sediment was found inStation I. In contrast, the organic matter within sediment was high when the acidity value decrease was observed at Station III.Keywords: Vegetation structure, mangrove, environmental factors, Dissolved Organic Matter, pH.

Abstract

This study aims to detect changes in mangrove cover using 30-meter resolution Landsat imagery in 2019 and 2021 and analysis of changes in density to macrozoobenthos abundance. The research method used is the analysis of satellite imagery with NDVI transformation integrated with field surveys, the relationship between mangrove density and abundance of macrozoobenthos was tested by regression analysis. The results showed that in 1 decade (2009-2021) there was an improvement in the quality of the mangrove ecosystem with an increase in the cover of the mangrove ecosystem by 5.49 Ha, which was accompanied by an increase in mangrove density. Improvement of ecosystem conditions also affects the increase in the abundance of macrozoobenthos in substrates, roots, and stems in mangrove ecosystems even though with a small coefficient of determination.
