Identifikasi Sampah Laut Makro Di Pantai Le Grandeur Kota Balikpapan Kalimantan Timur
AI summary Read the abstract
This Indonesian study identified and categorized macro-sized marine debris collected from Le Grandeur Beach in Balikpapan City, East Kalimantan, using 100 x 20 m transect surveys with 5 x 5 m subplots. Debris was sorted into plastic, glass, metal, rubber, wood, and other categories and quantified by count and weight. The results documented the composition and relative abundance of macro litter at this coastal site, with plastic representing a dominant fraction.
There is a lot of waste that is difficult to decompose and accumulates in nature, especially at the coastal and ocean, resulting in environment disturbance. This study was aimed to identify macro-size marine debris collected from Le Grandeur beach, Balikpapan City, East Kalimantan. A 100 x 20 m transect line was set at the beach. Each transect equipped with 5x5 m subtransect where the macro-debris was sampled. All debris in subtransect were collected and were cleaned prior sorted and grouped based on their categories namely plastic, glass, metal, rubber, wood and other types. Samples from each type were counted and measured in weight. Based on the results of the study, samples of macro marine debris collected at the study site were plastic, glass, metal, rubber, wood and others with a total debris of 435 items and total weight of 2,263.772 g/m2. Total density of waste is 86.6 particles/m2 with the percentage of each waste being 45% plastic, 0% glass, 2% metal, 2% rubber, 2% wood and 49% others.

AI summary Read the abstract
Researchers sampled seawater from Lamaru Beach in East Kalimantan, Indonesia, and found microplastics of three types: fibers, fragments, and films. The study provides baseline contamination data for this coastal area. The presence of microplastics in coastal seawater raises concerns for marine life and communities that depend on this ocean environment.
