Abstract

Sampah plastik yang menumpuk menyebabkan beberapa permasalahan baik pada ekosistem maupun lingkungan. Penguraian plastik baru dapat terjadi selama ratusan tahun ke depan. Sampah plastik yang mengalami fragmentasi menjadi mikroplastik dapat masuk ke perairan kemudian masuk ke tubuh organisme laut sehingga dapat mengganggu metabolisme pada tubuh organisme. Penelitian ini khususnya dilakukan pada perairan Muara Sembilang Kecamatan Samboja yang bertujuan untuk mengetahui jumlah, jenis, komposisi dan hubungan antara panjang ikan dengan jumlah mikroplastik pada saluran pencernaan Ikan Bandeng (Chanos chanos). Sampel ikan Bandeng diperoleh menggunakan alat tangkap belat di perairan Muara Sembilang, sampel ikan kemudian diukur, dibedah dan diambil saluran pencernaannya, selanjutnya  sampel didestruksi kering pada suhu 100oC selama 30 menit. Hasil penelitian menunjukkan tiga jenis mikroplastik yang didapatkan pada saluran pencernaan Ikan Bandeng, yaitu fiber sebanyak 6 partikel/ind, film dengan kelimpahan 4,7 partikel/ind dan fragmen dengan kelimpahan 3,8 partikel/ind. Hasil uji Korelasi Pearson menunjukan ukuran panjang ikan Bandeng tidak berkorelasi terhadap jumlah mikroplastik

Abstract

Plastic waste poses a significant threat to the global environment, particularly in coastal and marine ecosystems. Among its various forms, mesoplastics, measuring between 5 and 25 mm have attracted considerable attention. This study aims to identify and analyze the types, weights, quantities, compositions, and densities of mesoplastics found along Manggar Beach, a tourist destination in Balikpapan City, East Kalimantan. Sampling was conducted in two periods: April (Period I) and August (Period II) of 2022. A purposive sampling method was applied using a 100-meter transect line divided into 5x5 meter lanes, followed by the placement of 1x1 meter quadrats. In Period I, four types of mesoplastics were identified as film, fiber, fragments, and styrofoam, while only film was detected in Period II. A total of 43 mesoplastic particles (weighing 9.45 grams) were recorded in Period I, compared to just 5 particles (0.15 grams) in Period II. By weight, styrofoam made up the largest proportion (49%) in Period I, whereas film accounted for 100% in Period II. The average mesoplastic density observed in this study was 0.38 particles per square meter.

Abstract

Microplastics in waters is one of the problems in the coastal and marine environment. One of the areas affected by microplastics in coastal areas is the tourism beach. The purpose of this study was to determine the type and abundance of microplastics in the waters. This research was conducted in April - January 2023 at Seraya Beach, Balikpapan City. The data collection method was descriptive quantitative by describing and calculating the total abundance of microplastics. Water sampling was conducted at the sea surface (0-50 cm) during low tide condition. The research data were analysed by counting the total number of microplastic particles found, grouped, and calculated the abundance of microplastics using Microsoft Ofiice Excel and SPSS software. It was found that the type of microplastics in Seraya Beach was fragments (4666 particles), followed by fibres (560 particles) and films (218 particles). The fragment type was the dominant microplastic type in Seraya Beach waters with a total of 4666 particles, followed by fibre (560 particles) and film (218 particles). A significant difference (p<0.05) was found between the abundance and type of microplastics in Seraya Beach waters. In general, the presence of microplastics in Seraya Beach is influenced by geographical location, tourist activities on the beach and historical factors.

Abstract

The spotted scat (Scatophagus argus) is a nutrition source in the waters of Muara Pantuan, Mahakam Delta. However, anthropogenic activities from land have caused Lead (Pb) contamination in these waters, which has the potential to accumulate in fish. The purpose of this study was to determine Pb concentrations in various tissues of the spotted scat and analyze the associated human health risks from its consumption. A total of 8 fish samples were collected from Muara Pantuan waters with the assistance of local fishermen. Gill, digestive organ, and muscle tissues were digested using the acid digestion method, and Pb concentrations were analyzed using an Atomic Absorption Spectrophotometer (AAS) type iCE 3000. The results show the highest Pb concentration was found in the gills (0.04 ± 0.01 µg/g dry weight), while the lowest was in the digestive tract (0.03 ± 0.01 µg/g dry weight). The mean Pb concentration across all fish tissues ranged from 0.02 to 0.05 µg/g dry weight, which remains below the Indonesian National Agency of Drug and Food Control's (BPOM) standard of 0.20 µg/g. Correlation analysis between Pb and length (r = 0.80) and weight (r = 0.75) of the spotted scat showed a negative relationship with a strong correlation coefficient, but the relationship was not significant (p > 0.05). The Maximum Weekly Intake (MWI) calculation yielded the highest safe consumption limit for the adult group (43.8 kg/week), followed by adolescents (35.7 kg/week), and children (10.9 kg/week). Based on Pb concentration and health risk analysis, the spotted scat from Muara Pantuan waters is still considered fit and safe for human consumption.
