Abstract

Periphyton is an attached biota that lives on a substrate. Seagrass meadows and periphyton associate to form an ecological system. Seagrass meadows provide a place of attachment or habitat for periphyton organisms. Periphyton itself is one of the producers of primary productivity in the waters. Baluran National Park is one of the National Parks in which there are land and water habitats, and is a protected area that has natural and native ecosystems. Data collected to support this research included temperature, salinity, dissolved oxygen, pH, nutrients (nitrate and phosphate), seagrass cover data and periphyton data. Physical and chemical water parameters are taken directly on the spot or in-situ. Data collection on seagrass cover and periphyton samples was carried out using a 50 x 50 cm2 quadrant transect. Periphyton community structure analysis includes abundance, diversity index, diversity index and dominance index. Community structure is calculated to determine the community condition of a particular organism, to see its stability and presence in an area.

Abstract

Marine debris has emerged as a significant environmental issue of growing global concern, closely linked to pollution and its impact on the environment. Understanding the distribution of marine waste in coastal areas is crucial, especially considering that beaches are key sites for various human activities such as tourism, fishing, and shipping. To address this, a study was conducted to analyze the composition of marine debris on three beaches in Banyuwangi Regency, East Java. The study took place in July and August of 2023, focusing on Boom, Cacalan, and Cemara beaches. Marine debris was collected along the coastline in 5 x 5 m transects, spaced 20 m apart, to identify and quantify the types of waste. The findings revealed that Boom Beach had the highest percentage of rubbish (46%), followed by Cemara Beach (30%) and Cacalan Beach (24%). Additionally, the highest abundance of rubbish per area was found at Boom Beach (5.97 ± 16.64 item/m2), Cemara Beach (3,92 ± 11,36 item/m2), and Cacalan Beach (3,12 ± 5,27 item/m2). Boom Beach and Cemara Beach were primarily dominated by plastic waste, while at Cacalan Beach, plastic waste and broken glass were found in nearly equal proportions. The calculation of the Clean Coast Index (CCI) indicated that all three beaches were significantly polluted. As a result, there is a clear need for focused attention on waste management at tourist beaches to preserve the aesthetics and comfort of beach visitors.

Abstract

Sampah merupakan masalah telah menjadi krisis global dari daratan hingga lautan. Indonesia sendiri merupakan penghasil sampah plastik terbesar kedua di dunia. Salah satu sampah yang mendominasi di lautan adalah sampah plastik. Sumber sampah plastik yang bermuara di laut banyak berasal dari limbah industri dan rumah tangga. Keberadaan sampah plastik perlu diidentifikasi dan dianalisa kelimpahannya untuk menanggulangi dan mencegah persebarannya di lingkungan. Berdasarkan kondisi yang ada, artikel ini bertujuan untuk mengetahui komposisi jenis sampah plastik serta kepadatannya di kelima pantai yang berbeda di daerah Pasuruan. Penelitian ini menggunakan metode transek kuadran dengan ukuran 5x5 m yang dibentangkan di sepanjang kelima pantai tersebut dan diidentifikasi komposisi jenis sampah pada setiap transek kuadran tersebut. Hasilnya didapatkan bahwa Pantai Tambaan memiliki persentase sampah plastik tertinggi dan Pantai Panggungrejo memiliki kepadatan sampah tertinggi daripada wilayah pantai yang lain. Kedua pantai tersebut dekat dengan wilayah pemukiman dan terindikasi padatanya aktivitas antropogenik di kedua pantai tersebut, sehingga menyumbang sampah yang cukup signifikan terutama sampah plastik.   Waste is a problem that has become a global crisis from ldan to sea. Indonesia is the second largest producer of plastic waste in the world. One of the dominating waste in the ocean is plastic waste. The source of plastic waste that empties into the sea comes from industrial dan household waste. The presence of plastic waste needs to be identified dan analyzed for its abundance to overcome dan prevent its spread in the environment. Based on the existing conditions, this article aims to determine the composition of plastic waste types dan their density on five different beaches in the Pasuruan area. This study used the 5x5 m quadrant transect method along the five beaches dan identified the composition of waste types in each quadrant transect. It was found that Tambaan Beach had the highest percentage of plastic waste dan Panggungrejo Beach had the highest density of waste compared to other beach areas. Both beaches are close to residential areas dan indicated the density of anthropogenic activities on both beaches, thus contributing significant waste, especially plastic waste.
