Abstract

Microplastic in the oceans might interfere the health of marine organisms, including the green mussels (Perna viridis). This is due to microplastic accumulation in mussels organs, such as gills, hepatopancreas, and gonads. Therefore, tissue alteration is a good indicator for ecological risk analysis and other ecotoxicological study activities. Green mussels with shells 4.1 to 5.0 cm in length were collected from Mandalle waters, Pangkep Regency (Pangkajene Islands), Indonesia. Green mussels were exposed for seven days to microplastic with concentrations of  0.05 (A), 0.5 (B), and 5 (C) g/L. The results showed that the higher the concentration of microplastics exposed to the green mussel, the higher the accumulation of microplastics in the body of the mussel, within the tested concentrations. The increased concentration of microplastics increased the level of tissue alteration in the gills, hepatopancreas, and gonads, with the most sensitive organ being the hepatopancreas. Overall, the study confirmed that the histological assay of mussel organs could be used as a biomarker in ecotoxicological studies.

Abstract

Estimating the number of phytoplankton is something important in the field of aquatic science, including the field of aquatic ecotoxicology. Turbiditimeter is a device that can determine the level of turbidity of the water both caused by non-organic and organic matter, such as phytoplankton. Preliminary research has been conducted to estimate the number of phytoplankton, Spirulina, using turbiditymeter. The results showed that the correlation between the number of Spirulina which was directly estimated using the haemocytometer and the turbidity level detected by the turbiditimeter was statistically very strong and significant statistically (R = 0.9762 and S = 0.012). The linear equations of the correlation can be used to estimate the number of Spirulina with an error of 4.17-20.99% indirectly.  The conclusion of this study is that turbiditimeter can be used to predict the number of phytoplankton indirectly.Keywords : Quick assesment, ecotoxicology, Spirulina sp, turbidimetry, revolution, industry 4.0

Abstract

Highlight Research Based on technological and economic dimensions, the sustainability of seaweed cultivation in Ekas Bay was less sustainable (index value lied between 26 and 50). The distance between seed clumps, drying places, seedling binding locations, and warehouses were the most sensitive attributes from technological dimension. Market status, market scale, and target market were the most sensitive attributes from economic dimension   Abstract Indonesia is one of the major countries in the world that produces seaweed. West Nusa Tenggara has become one of the centers of seaweed producers in Indonesia because it has many bays that are used for seaweed cultivation activities. The problem of seaweed aquabusiness is the low productivity of the production unit managed by seaweed farmers. This study aimed to assess the effectiveness and production level of seaweed cultivation technology and the success of seaweed cultivation by seaweed farmers in Ekas Bay based on technological dimensions (17 attributes) and economics (14 attributes). The Rapsewaqua application is used to analyze the sustainability status of seaweed cultivation. Based on the results of the analysis, the index value was 50.08 for the technology dimension and 39.50 for the economic dimension. The result showed that the sustainability of seaweed in Ekas Bay was in the less sustainable category. Spacing between seed clumps, drying area, seedling binding location, and warehouse were the most sensitive attributes on the technological dimension. Market status, market scale, and target market were the most sensitive attributes in the economic dimension. These sensitive attributes need to be improved to support the sustainability of seaweed in Ekas Bay.

Abstract

Kegiatan pengabdian ini bertujuan meningkatkan kompetensi digital Pemuda Karang Taruna Multimedia melalui pelatihan desain produk menggunakan Canva serta pengenalan strategi pemanfaatan platform e-commerce sebagai upaya memperluas peluang ekonomi digital. Program dilaksanakan dengan pendekatan Asset-Based Community Development (ABCD) yang dipadukan dengan Participatory Action Research (PAR) untuk memastikan keterlibatan aktif peserta dalam proses perencanaan, pelaksanaan, hingga refleksi. Hasil pelatihan menunjukkan peningkatan pemahaman peserta terhadap prinsip desain visual, penyusunan materi promosi, dan pembuatan konten yang relevan untuk pemasaran digital. Sesi pengenalan e-commerce memberikan gambaran menyeluruh mengenai alur pembuatan toko online, optimasi tampilan produk, serta strategi promosi melalui tips dan trik yang disampaikan narasumber. Meskipun peserta hanya mengikuti demonstrasi tanpa praktik langsung, kedua pelatihan ini efektif dalam memperkuat literasi digital, kreativitas, dan kesadaran peserta terhadap potensi ekonomi digital. Program ini berkontribusi pada pemberdayaan pemuda agar lebih adaptif terhadap perkembangan teknologi dan mampu memanfaatkan platform digital sebagai sarana pengembangan usaha yang berkelanjutan.

Abstract

Plastic waste continues to increase all the time without decreasing or ending, resulting in the sustainability and restoration of the mangrove ecosystem needing to be improved. The mangrove ecosystem is a place where plastic waste accumulates. The accumulation of plastic waste prevents photosynthesis in mangroves, reduces aquatic productivity and encourages microbial colonization. This research aims to identify the type abundance of plankton, waste and water quality. Sampling was carried out purposively from June to July 2023. STA 1 represents rivers, STA 2 was estuaries and STA 3 was coastal mangroves. Plankton, plastic waste and water quality samples were collected at the beginning of each month based on a 1x1 m2 plot. Furthermore, biological index calculations of plankton and the density of plastic waste were carried out and their relationship with water quality in each location. Mangroves in the village of Pagatan Besar are dominated by Avicennia marina, Avicennia alba, Bruguierra cylindrica and Rhizopora apiculata. The highest density of was in STA 3, but it was inversely proportional to the abundance and diversity of plankton due to the dense waste cover between the roots, mainly plastic materials. The most significant increase in marine waste accumulated in STA 3 from 6697 grams at the beginning of the observation to 13820 grams. The most significant composition of waste in STA 3 consists of plastic bottles and plastic cups. Cyanophyta, Chlorophyta and Chrysophyta are plankton phyla from the research location. Plankton identified there are three phyla in STA 1 and STA 2, while in STA 3, there are only 2. Cyanophyta, Chlorophyta and Chrysophyta are phyla plankton from the study site. The types of plankton that are always present in all STAs are Gonatozygon and Ulothrix from Chloropyta. The survival of plankton and mangroves is influenced by water temperature, pH, salinity, dissolved oxygen and the type of material density of macroplastic waste.Keywords:MacroplasticMangroveWater QualityPlankton
