Abstract

Mangrove degradation is one of the most common issues in the coastal areas of Java, which can cause ecological impacts and even disadvantage for local community. The mangrove forest degradation can be identified based on the vegetation analysis results, which could potentially contribute to the mangrove ecosystem management and rehabilitation programs in the coastal areas. Mangroves in Keboromo Village was the rehabilitation and cultivation area, but often get damaged by ocean waves. This study aims to determine the ecological and vegetation conditions of mangrove ecosystems consist of species composition, density, canopy cover, tree height, and environmental parameters were held in February 2023. The method used was direct observation using transect quadrants of 10x10 m2. The average mangrove density of all observation stations was 3.425 individuals/ha for the tree category, 575 individuals/ha for the sapling category, and 250 individuals/ha for the seedling category. The average percentage of canopy cover was 78.41%. The average height of mangrove trees at all stations is 4.15 m. The environmental parameters were still compatible with the water quality standard for biota and mangrove life. The mangrove forest degradation level based on standard criteria and guidelines for determining mangrove degradation is categorized as low, indicated by mangrove density >1500 individuals/ha and canopy cover >75%. Poor conditions were measured for sapling and seedling densities, which may be caused by environmental factors unsupportive for mangrove regeneration. Based on the results of mangrove vegetation analysis in Keboromo Village, it can state the mangrove ecosystem condition is good. However, management programs are needed to keep the mangroves sustainable.

Abstract

Despite being operated on a small scale, Blue Swimming Crab (BSC), Portunus pelagicus fishery substantially contributes to Indonesia's fisheries as the country's third-largest export commodity after tuna and shrimp. The high of BSC’s demand led to pressure on its stock. Hence a conservation area is needed to be set up, in this study, was proposed using reproduction indicators. with the case study of BSC Stock in Keboromo Waters, Pati Regency, North Central Java. The samples were collected from 38 sampling points at a distance of 2-12 miles from the coastline during November-December 2022 using collapsible crab traps.  A reproduction observation on female crabs was carried out on their carapace width and gonad maturity stage. The data then were analyzed for the percentage of egg-berried females (EBF), size at first maturity (Lm) and first captured (Lc), and their spawning potential Ratio (SPR).  This study found that the mature crabs (GMS2) in November and December were higher than in other stages while the proportion of ovigerous females (EBF) in December was higher than in November. At several sampling points, the size at first captures (Lc) was higher than that at first maturity (Lm) indicating a decrease in resource stocks due to a delay in the recruitment process. SPR of 19% showed that reproductive potential should be maintained before recruitment is limited, therefore based on the existence of EBF in particular sampling points it is recommended three conservation areas as a temporary no-take zone in BSC fishing ground in Keboromo Watres, Pati Regency.

Abstract

Segara Anakan Mangrove Forest in Cilacap is one of the most extensive mangrove forests on the southern coast of Java Island. This study aims to determine the level of herbivory and environmental conditions. The sampling technique used was purposive random sampling, which considered the different characteristics of the vegetation. Sonneratia caseolaris dominated Station 1, while Station 2 was more diverse, including Avicennia marina, Avicennia alba, Rhizophora mucronata, Sonneratia caseolaris, and Aegiceras corniculatum. Each station is spread over three points, each with five sampling plots, representing the distribution and zonal homogeneity of carrying capacity. The research was conducted in May, August, and November 2023, based on the different temporal seasons in Indonesia. The results showed biotic factors from herbivory activity and abiotic factors such as the hydrological cycle caused mangrove leaf damage. The class of leaf damage caused by herbivory at all observation stations was mainly in class I (<2.5%). The most leaf damage was found in old leaves, which is related to the optimal photosynthesis process producing carbohydrates as a food source for herbivores. Additionally, tannin content in the leaves plays a role in protection from excessive UV radiation during the dry season. This condition indicates that Segara Anakan mangrove forest is still in good condition. PCA analysis results show that mangrove leaf damage is closely related to the age of the leaves.

Abstract

Mangrove canopy cover plays an important role in maintaining and protecting environmental stability in coastal areas, namely as a habitat for various terrestrial species and as protection from direct exposure to ultraviolet light on associated aquatic organisms. Mangrove canopy cover is important in protecting coastal areas from strong winds. This research aims to analyze the condition of the mangrove area, the condition of canopy cover based on the NDVI value and the percentage value of canopy closure, and the relationship between NDVI and percentage canopy closure. Sentinel-2B image data was processed using QGIS 3.28.13 and ArcGIS 10.8 software. Maximum likelihood classification is used to separate mangrove delineation from other objects, and an accuracy test is carried out using a confusion matrix to test the accuracy of the classification results. Observations were determined using a purposive sampling method, and canopy closure data was collected using a simple hemispherical photography method. The condition of canopy cover was analyzed based on NDVI calculations and calculation of the percentage of canopy closure, which was carried out using image-j software and Microsoft Excel 2010. The analysis showed that ten types of mangroves included seven families and eight genera with a mangrove area of 21.66 ha. 62.70% of the mangrove area has a canopy cover condition based on the NDVI value, which is very dense. Also, 50% of observation stations have a canopy cover condition based on the canopy cover percentage value, which is still classified as dense. The correlation between the NDVI value and the percentage value of mangrove canopy cover has a unidirectional relationship and a very strong relationship with a correlation coefficient r of 0.949.  Tutupan Kanopi mangrove sangat berperan penting dalam menjaga dan melindungi kestabilan lingkungan pada wilayah pesisir, yaitu sebagai habitat bagi berbagai macam spesies terestrial dan juga sebagai pelindung dari terpaan sinar ultraviolet secara langsung terhadap organisme perairan yang berasosiasi, tutupan kanopi mangrove juga sangat berperan penting dalam menjaga dan melindungi wilayah pesisir dari terpaan angin kencang.

Abstract

Pemalang Regency has a mangrove area of around 2,839.44 but has been damaged reaching 453.38 Ha or about 16% of the existing area. This causes ecological functions in resisting abrasion, erosion, sedimentation, and carbon capture to decrease. Government efforts to restore the function of mangroves on the North Coast of Central Java carried out by rehabilitation require input from a water productivity approach. This study aims to determine the content and distribution of chlorophyll-a found in Pemalang Waters, Central Java. This was done by in situ observations in Pemalang Waters to see the fertility level of the waters, by purposive sampling at 20 sampling site, on April 30, 2024. The results obtained will be interpolated with ex situ data, including the Indonesian Earth Map (RBI), tidal data obtained from the SRGI website, flow data obtained from the Batnas website, and wind data obtained from the BMKG website. The next geospatial approach is ODV 4, Ms.Excel, and WR Plot application mapping; current analysis will be performed using ArcGIS 10.8 and Mike 21 applications; while the tidal analysis is carried out by the Admiralty method. The results of research conducted in Mojo Waters, Pemalang showed that the range of chlorophyll-a values was in the range of 1,858 - 41,287 mg / m3. The results were analyzed in sampling areas including rivers, estuaries, lagoons, eastern drift currents, western drift currents, waters still affected by estuaries, and the high seas. The distribution of chlorophyll values in these waters is the impact of nutrient supply from land because it is closely related to human activities, freshwater and seawater resuspension, drift currents, breaking waves, tidal currents. This causes the distribution pattern to occur from northeast to southwest.

Abstract

Mangrove litter is a critical component of the nutrient cycle, reflecting soil fertility and water quality within the mangrove ecosystem. This study investigates the dynamics of litter productivity in the Segara Anakan mangrove forest in Cilacap. The study area is divided into two locations with three points, with five litter traps installed at each point. Sonneratia caseolaris dominates vegetation characteristics at Station 1, while Station 2 has more diverse vegetation, including Sonneratia caseolaris, Aegiceras corniculatum, Acanthus ilicifolius, Derris trifoliata, Rhizophora mucronata, Avicennia alba, and Avicennia marina. Sampling follows seasonal changes in Indonesia, covering June 2023 to March 2024. The primary data for this study include aboveground litterfall production, estimated using litter traps, and the litter layer on the forest floor collected through soil transects. Secondary data comprise weather measurements, including air temperature, rainfall, wind speed, and humidity. Litterfall and litter layer were collected four times: June (dry season), September (transition from dry to rainy season), December (rainy season), and March (transition from rainy to dry season). The results indicate a total litter productivity of 18.99 tonnes ha-1 yr-1. The lowest litter production was observed in September, while the highest was in March. Leaf litter contributed the most, accounting for 71.49%, followed by twigs at 19.19%, flowers/fruits at 8.31%, stipules at 0.62%, and the lowest portion from other unidentified materials at 0.39%. Litter productivity shows a strong correlation (0.99) with rainfall. The main factors influencing litter productivity include environmental factors, primarily rainfall, and physiological factors, such as flowering and fruiting phenology.

Abstract

Around 20% of mangrove forests in Indonesia are in a degraded condition, which has a negative impact on the potential for blue carbon storage. When mangroves are damaged or degraded, carbon stored in the soil and vegetation can be released back into the atmosphere as CO2, ultimately increasing greenhouse gas emissions and exacerbating climate change. Mangrove forests can store up to four times more carbon per hectare, around 8001,200 tons per hectare, than terrestrial tropical forests. This research was conducted in the Wini mangrove forest area, North Central Timor, East Nusa Tenggara (NTT) which directly borders Timor Leste. The determination of the location of the observation station was based on a map of changes in mangrove forest land use obtained from the Geospatial Information Agency. The parameters measured included organic carbon, mangrove area and sediment type. Organic carbon was analyzed using the Loss on Ignition (LOI) method, and sediment grain size was measured using a particle size analyzer. The results of the study showed that the average organic carbon stock in mangrove forests reached 570,600843,600 tons per hectare, with an average change in the area of mangrove forests from 2013 to 2023 of 181.29 hectares and the type of sediment dominated by sandy mud. This change in area is caused by the conversion of mangrove land into ponds, rice fields, and settlements.Keywords:MangroveCarbonSedimentborder Area

Abstract

Abstract Mangrove forests in Timbulsloko and Bedono have very dynamic conditions, due to tidal flooding and land subsidence that occur in these areas. Meanwhile, mangrove forests in the Timbulsloko and Bedono Village play an important role in preventing abrasion which often occurs in these areas. The importance of the mangroves function in this area makes it crucial to monitor their condition. Monitoring the condition of mangroves can be done by looking at their density through the vegetation index. Therefore, this study aimed to determine the best vegetation index to be used in the Timbulsloko and Bedono villages to monitor mangroves in 2016-2018, 2020, and 2022. The method in this research consisted of two stages, namely sentinel 2 image processing and the field survey. Image processing was used to determine the condition of mangroves based on several vegetation indices. Meanwhile, data collection in the field was utilized to validate several vegetation indices used in this study and conducted with the hemispherical photography method. Linear regression analysis was used to determine the most suitable vegetation index to be applied in the study area. The study found that NDVI vegetation index had the highest accuracy value, followed by SAVI, EVI, and MVI. The use of NDVI to see the changes in mangrove conditions showed an increase in the total area in each category. So, it can be concluded that the area and density of mangrove forests in the Bedono and Timbulsloko villages increased every year. Highlight Research Mangroves in each region have different canopy density values. The use of the mangrove vegetation index will produce different accuracy values in different areas. LAI has a very strong relationship with the NDVI. The addition of area in the sparse mangrove category can be an indication of mangrove planting at the most recent time. In general, the research outcome will be valuable recommendation for mangrove rehabilitation in current target area.
