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.
