Abstract

Waste is one of the problems for people all over the world, marine debris can come from community activities from the mainland or from the coast. Most of the activities of coastal communities may produce waste including fishing and tourism activities. Research on plastic waste in the Tourism Beach area of Muara Badak District was conducted to identify the type of mesoplastic, analyze the total weight, density and proportion of mesoplastic and determine differences in mesoplastic. This research was conducted at two tourist beach locations, namely Panrita Lopi Beach and Jingga Beach. The research method used was Purpusive Sampling method with recycling and making transect lines with a size of 100 m × 20 m, followed by dividing the transect into 5 lanes measuring 5 m x 5 m. Four types of mesoplastic were found, namely film, fiber, fragment and styrofoam. The amount of trash found on both beaches was 53 particles with the number of particles on Panrita Lopi Beach as many as 32 particles and Jingga Beach was 21 particles. The results of the composition of the percentage of waste obtained at Panrita Lopi Beach were 50% for fragment types and at Jingga Beach for 71% for filament types. The most common amount of trash found was at Panrita Lopi Beach, this was due to the fact that the number of visitors was greater than that of Pantau Jingga.  The relationship between length and weight of waste at Panrita Lopi Beach was 94% while at Jingga Beach it was 58%.

Abstract

Aquatic insects play a crucial role in ecological systems because they are sensitive to environmental changes, indicating whether an environment is healthy or polluted. The vast biodiversity in morphology, physiology, and adaptive behavior among insect species on Earth has led to numerous scientific studies using insects as models. Population dynamics studies, for instance, often rely on the evolution of insect populations. The objective of this research is to explore the types of aquatic insects present, as well as their diversity, evenness, and dominance levels. The study found 4 orders and 4 families totaling 180 individuals on the leaf litter of water lettuce. The diversity index of aquatic insects on the water lettuce leaf litter was categorized as low. The evenness index was categorized as small. The dominance index ranged from low to moderate to high categories.

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.
