Abstract

Mangrove forests in Timbulsloko and Bedono villages have very important benefits in minimizing abrasion, due to tidal flooding and land absorption in this area. A large number of people have planted mangroves to restore the function of mangrove forests in coastal areas which conducted by NGOs, students, government agencies, and awareness from local residents. This study aimed to determine the dynamics of mangrove area and mangrove species dominant area changes in 2016, 2018, 2020 and 2022 based on Sentinel-2 Satellite Imagery processing, and to analyze the dynamic changes based on geospatial analysis. The method used in this study is divided into two: satellite imagery data processing and field survey. The result showed that the area of mangrove species in Timbulsloko and Bedono increased from 2016 to 2022. In 2016 the area of mangroves was 140.04 ha, 159.57 ha in 2018, 171.05 ha in 2020, and 234.8 ha in 2022. The use of Sentinel 2 Satellite Imagery to map the distribution of mangrove species dominant produce overall accuracy of 84.62%. The mangrove species with the highest area are Avicennia marina followed by Avicennia alba, Rhizophora apiculata, and Rhizophora mucronate. The increase in this area of mangroves in this area is due to natural additions and artificial additions due to mangrove planting conservation by several parties and the awareness of the local residents to protect mangroves.Keywords:Mangrove SpeciesDynamicsCoastal AreaSentinel 2Remote Sensing

Abstract

Water quality is influenced by the high activity in the port area, resulting in decreasing water quality. The biological parameters based on the structure of the aquatic community of organisms that act as bioindicators could be indicated as changes in water quality around the port. Bioindicators are a group of living organisms susceptible to environmental changes due to human activities and natural damage. One of the aquatic organisms that can be used as an indicator of water quality is Benthos because of its sedentary nature. This study aims to determine the quality of the water environment seen from the benthic community structure, namely density, diversity index, uniformity and dominance index, to embody the clean and pollution-free Kutaraja Fishing Port. The research shows that the aquatic environment of Kutaraja Fishing Port is included as the less stable category with a moderate diversity value (H' 1) but has high benthic individual uniformity (E 0.6), which means that individuals are evenly distributed a low dominance value or C is close to 0.Keywords:Water qualityBio-indicatorBenthosKutarajaBanda Aceh

Abstract

Crabs are a member of the mangrove ecosystem fauna and get their food source from litter. They turn the litter into detritus and maintain ecological balance. In addition, environmental conditions in the mangrove ecosystem also play an essential role in the abundance of brachyuran crabs. Influential environmental factors include temperature, salinity, water pH, and substrate type. This study aims to determine the effect of environment types on the presence of brachyuran crabs from families Ocypodidae and Sesarmidae in the mangrove ecosystem in Gemuruh River, Koto XI Tarusan District. The method used is a descriptive method, which is a direct observation approach to crabs and environmental conditions in the mangrove ecosystem area. Collection of crab samples and environmental condition data used a purposive sampling technique. The result shows six species distributed in the area, namely Uca bellator, U. rosea, Perisesarma eumolpe, Sarmatium germaini, P. plicatum, and Sesarma curoense. The distribution of species crabs in vegetation mangroves is Rhizophora stylosa, R. apiculata, R. mucronata, Sonneratia alba, and Nypa fruticans. The environmental parameters (temperature, salinity, water pH) at each station were within the relatively good category for the growth of the Ocypodidae and Sesarmidae crab families. Based on the analysis results of the relationship between the abundance of brachyuran crabs and environmental parameters (temperature, salinity, water pH), it can be seen that there is no significant correlation between temperature, salinity, and water pH with the abundance of Ocypodidae and Sesarmidae brachyuran crabs families in the mangrove ecosystem of Gemuruh River. The factor with a dominant influence on the abundance of these crabs is the substrate type.Keywords:AbundanceKoto XI TarusanMangroveOcypodidaeSesarmidae

Abstract

Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm±0.24); absolute weight growth (5.47g±0.45), specific daily growth rate (2.28%/day±0.13) and the highest tilapia biomass production (480g/0.5m2±19.25). The highest survival rate was found in treatment C (82.42%±2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

Abstract

The lobster aquaculture industry has a high dependence on natural catch. Hence, lobster farming has become necessary. The waters in Sabang have the potential for developing lobster mariculture, but data is not yet available on the conditions of the aquatic environment that are suitable for lobster farming. This research aims to determine which locations are suitable for lobster mariculture activities in the waters of Sabang. The research parameters are divided into geographics, physicochemical, and supporting parameters. The geographical parameters group was collected through in-situ observations, and physicochemical parameters were measured in-situ and laboratory tests, supporting parameters through observations. Initial data analysis used the SAW (Simple Additive Weighting), AHP (Analysis Hierarchy Process) methods, and spatial analysis to determine the suitability of lobster cultivation zones with the Geographic Information System (GIS). From the observations of geographical parameters, the three locations of the observation station were in the very suitable category. The results of measuring physicochemical parameters group in three research locations were very suitable. Based on observations of other supporting parameters, Lhok Krueng Raya is very suitable for the cultivation zone, while Teupin Sirui and Lhok Weing are suitable. The findings of this research indicate that location protection, accessibility, DO, and COD are limiting parameters for selecting a suitable location for lobster mariculture in Sabang waters.Keywords:Suitability analysisLobster farmingSabangGIS

Abstract

Mangrove has numerous ecological functions, such as a habitat for various biota, a place of care and rearing, with a microclimate regulator and spawning. This ecosystem can store the highest carbon compared to tropical, subtropical, and boreal forests. This research aimed to model the estimation of mangrove carbon stocks using drone images. The method used consists of several steps as follows: (1) Taking and analyzing drone images, (2) Identification and estimation of biomass with carbon stocks, (3) Modeling of mangrove carbon stock using drone and field data. The results of mangrove carbon estimation using logarithmic regression of drone images were the best, by the equation y = 0.0455ln (x) + 0.244. Therefore, the results showed that the R2 value was 0.7454, with the RMSE accuracy-test being 689.9 kg, at 35.4%.Keywords:DronesMangroveCarbon stock
