Abstract

Seagrass beds are highly productive ecosystems and have ecosystem services in the coastal zone but are continuously declining globally. Mainly due to anthropogenic activities that reduce the amount of light entering the waters and reaching seagrasses, such as dredging, reclamation, sedimentation, and eutrophication. This research was conducted to determine the relationship between turbidity level and seagrass composition and morphology. The observations were conducted in November 2016 in Pangkep district on Sagara Island and Makassar City on Barrang Lompo and Lae-lae Island, South Sulawesi Province. The observation stations are determined based on the level of turbidity conditions. Sagara Island, Barrang Lompo, and Lae-lae are areas that are considered to represent turbid waters, by laying a line transect (roll meter) perpendicular to the coast and doing it 3 times. The data collected in this study related to seagrass conditions such as seagrass composition and seagrass morphometrics. Variables observed in seagrass leaf morphometric observations were leaf surface area and leaf width, leaf thickness, and distance between internodes. In addition, other data collected is environmental parameter data, such as currents, TSS, PAR, temperature, and salinity. One-way ANOVA analysis showed that there was a difference in turbidity levels between Barrang Lompo Island, Sagara Island, and Lae-lae Island with a significance value of 0.000. The types of seagrasses found on Barrang Lompo with light availability of 1735.23 mol/m/s are Enhalus acoroides, Cymodocea rotundata, Halodule uninervis, Halophila ovalis, Thalassia hemprichii. On P. Sagara with light availability of 170.01 mol/m/s, E. acoroides, T. hemprichii, Cymodocea serrulata, H. uninervis, and H. ovalis were found. Whereas in P. Lae-lae only E. acoroides was found. The results showed that the level of turbidity has an influence on seagrass morphometrics, namely leaf ratio and leaf thickness of E. acoroides species, and internode distance in H. uninervis species.Keywords:Availability of lightMorphometricsPARSeagrass bedsTurbidity

Abstract

This community service initiative aims to enhance awareness and encourage active participation among the residents of Peunaga Cut Ujong Village, Meureubo Subdistrict, West Aceh Regency, in environmental conservation efforts through mangrove planting. Located in a coastal area vulnerable to erosion and exposed to air pollution due to coal-burning activities, this village faces significant environmental challenges. Employing an educational and participatory approach, the program involved raising awareness about the ecological functions of mangroves and conducting direct planting activities in a mangrove forest area approximately 100 meters from the shoreline. The outcomes of the initiative indicated a positive response from the community, demonstrated by increased environmental awareness and active involvement in conservation efforts. Mangrove planting is expected to function as a coastal protection barrier, an air pollutant absorber, and a potential site for ecotourism and aquaculture development. This initiative highlights the importance of synergy between academia, the local community, and the industrial sector in creating sustainable environmental solutions. Continuous evaluation and the replication of similar programs are strongly recommended to enhance their long-term impact.

Abstract

Seagrass beds are one of the coastal ecosystems that have an important role in maintaining the balance of the marine environment. Indonesia is known for its rich seagrass species but not much has been reported, especially in Aceh waters.This study aims to identify and analyse the distribution and condition of seagrass health through the percentage cover and dominance of seagrass species in Pulau Banyak District, Aceh Singkil Regency. Seagrass research was conducted in July 2024 at 3 different stations, namely Nago, Matahari and Panjang Islands. The research method used was the method of drawing a 100 m long line transect, with each station being repeated 3 times at 50 m, so that the seagrass area observed was 100 m2. Differences in the condition of the aquatic environment showed differences in the presence of seagrass species found. A total of 4 seagrass species were recorded in this study, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata and Halophila ovalis. There is a difference in the number of seagrass species found in the 2015 and 2023 time periods, the 2024 survey recorded 4 species from the previous 5 seagrass species. The highest percentage of seagrass cover was found on Nago, Matahari and Panjang Islands with percentages of 19.98%, 3.69% and 1.23% respectively. The highest overall seagrass species cover was T. hemprichii at 60.268%, while the lowest seagrass species was H. ovalis at 3.534%. Based on the results of the analysis of the percentage of seagrass cover of the entire research station, it is concluded that seagrass in the waters of Pulau Banyak is included in the category of sparse cover, with poor condition status (≤29.9).

Abstract

The coral reef ecosystem on Seureudong Island, Sawang Bau Village, Sawang District, South Aceh is very important for the surrounding ecosystem, with the fringing reef type, namely the shape of its growth around the island. This study aims to determine the current condition of coral cover and the types available on Seureudong Island. The method used is the Point Intercept Transect (PIT). The results showed that the forms of coral found at the study site were branching, digitate, encrusting, foliose, massive, mushroom, plates, and submassive. The percentage of the bottom substrate is dominated by hard coral (hard coral) at 45.3%, Dead Coral with Algae/DCA (37.11%), and (9.89%), rubble of 3.56%, rock (1.56%), algae turf (1.44%), macroalgae (1%) and dead coral (0.11%). At the study site, 25 genera were found with Porites (36%) as the most common genus found. At the research location, there are also genera with a total presence of less than 1%. These genera are Acanthastrea, Ctenactis, Favia, Favites, Fungia, Gardineroseris, Goniopora, Halimeda, Heliopora, Hydnophora, Leptastrea, Montastrea, Pavona, and Seriatopora. The quality of the waters at the research location still complies with the standards of coral life. The results of these observations must be carried out periodically so that they can always update the condition of the coral reefs on Seureudong Island

Abstract

This study was undertaken in September 2023 in the West Aceh Coastal area with the goal of identifying and analyzing the distribution of marine creatures discovered at the two research sites. The sampling of marine debris was determined using a transect length of approximately 100 m. Transect distances were separated into four categories: 0, 25, 50, 75, and 100 m. Marine debris was detected using Lippiat et al. (2013) categories and NOAA (2013) size classifications. The data on the identification and distribution of marine debris was analyzed descriptively. The results revealed that organic waste (wood and its derivatives) was in the highest quantity and composition at both research stations, with 1386 (73%) and 8953 fractions (97.1%). This is followed by the number and composition of inorganic waste (plastic) at the two research stations, which are 492 fragments (26%), and 205 fragments (2.2%). The lowest amount and composition of inorganic waste (non-plastic) were found at both research stations, such as metal/metal, glass, rubber, and clothing/other fibers, namely (metal: 6 and 11; glass: 2 and 1; rubber: 2 and 28; clothing and other fibers: 18 and 24) with respective compositions ranging (metal: 0.3% and 0.1%; glass: 0.1% and 0.0%; rubber: 0.1% and 0.3%; clothing and other fibers: 0.9% and 0.3%). A one-way examination of the spatial distribution of marine debris at each research substation (Substations 1, 2, and 3) revealed no significant differences (p value > 0.05) between the two research stations.  Keywords: coastal, debris, marine, West Aceh

Abstract

Silicate fertilizer is a micronutrient that is widely used by phytoplankton in its growth and development process. One type of microalgae that utilizes this nutrient is Skeletonema costatum. The growth of Skeletonema costatum is strongly influenced by the availability of nutrients, especially silicate, which functions in the formation of diatom cell walls. This research aims to determine the density level of Skeletonema costatum when applying silicate fertilizer at different doses on a laboratory scale. This research used an experimental method with four doses of silicate fertilizer, namely 3 ppm, 5ppm, 10ppm, 15ppm and 20ppm. The S. costatum culture was observed for 10 days under controlled laboratory conditions. The parameters observed were cell growth and density which were calculated every day using a hemocytometer. This research shows that applying silicate fertilizer at optimum doses can increase the growth of S. Costatum phytoplankton which is useful as natural food in aquaculture. The results of this study show that administration of silicate at a dose of 20 ppm was able to produce a cell density of 1.946.250 cells/ml. The growth of S. Costatum showed a significant increase in number, marked by the addition of 7-12 filaments. The most appropriate harvest time is in the exponential growth phase. Meanwhile, the results of measuring water quality parameters show values that are still within the optimal range for the growth of S. Costatum.

Abstract

Damage to mangroves on the West Aceh coast due to the disaster tsunami and the increasing utilization of economic activities towards the beach area makes mangrove planting activities necessary. Service activities aim to support the benefits of conservation and expansion of mangrove ecosystems on the Coas of Peunaga Cut Ujong, Meurebo District, West Aceh Regency. This planting activity is a collaborative activity between industry players, academics, and the surrounding community which was initiated by PT MIFA Bersaudara as a form of concern for the environment and concrete action in contributing to coastal ecosystem conservation, especially for achieving the SDGs. The types of mangroves planted were Rhizophora apiculata and Rhizophora mucronate. This planting uses a planting method with artificial regeneration which involves planting seeds, propagules, or mangrove seedlings by moving the seedlings to a new location. Mangrove planting activities in Peunaga Cut Ujong managed to get attention and attention from the village community. Not only involved directly in mangrove planting activities but also committed to the maintenance and monitoring of the planted mangroves. In addition, the success of mangrove planting is also evident from the low mortality rate (5%) of the seedlings. The addition of more leaves, height, and mangrove roots that have begun to appear in some mangrove stands was observed seven months after planting.
