Seasonal effect on the spatial distribution of macro debris in Tunda Island, Banten

Abstract

The small island coast is an area that is vulnerable to environmental problems. Debris problems occur in some areas of Tunda Island with low human activity, due to current and wind factors that can distribute the debris. The speed and direction of wind and currents in Indonesia are influenced by the seasons, so the seasons have an influence on the accumulation of debris in a place. This study aims to determine the effect of the season on the distribution of debris and potential sources that influence the presence of debris on the coast of Tunda Island, Banten. This study uses MIKE 21 software to determine current and wind patterns and movement of macro debris particles. Based on season research, it influences the pattern of macro debris distribution in this area. In the east season, the increase in the litter is 9 kg from the weight of the debris in the west season. Also, there is an increase in debris in several categories including the most likely to find items, fishing gear, packaging material, small pieces trash, and base wood materials. The potential source that affects the presence of debris on the coast of Tunda Island, Banten is Muara Ciujung.

Assessing plastic size distribution and quantity on a remote island in the South Pacific

“…Spatial and temporal trends are an important aspect of ecological research, including quantifying and predicting plastic accumulation patterns over time. However, gathering the necessary, robust datasets can be extremely challenging due to the variability in sampling and reporting methods, difficulty associated with working in remote areas (i.e., dangerous weather conditions; Browne et al, 2015), and seasonality in debris accumulation (Maharani et al, 2020;Ríos et al, 2018). For example, seasonal variability was identified in the remote island beaches of the Azores archipelago, likely a result of temporal wind exposure, and human influences (i.e., tourists more prevalent in summer leading to more beach clean-ups in this season) (Ríos et al, 2018).…”

Menentukan Potensi Sumberdaya dan Daya Dukung Ekowisata Pulau Tunda, Kabupaten Serang Banten

“…Pulau Tunda memiliki karakteristik pantai dengan substrat pasir putih dominan berkarang dengan lebar pantai rata-rata 7,90 m dengan kemiringan rata-rata 8,15 o serta panjang pantai rata-rata 7878 m. Namun, banyaknya sampah di sekitar bibir pantai terutama pada bagian selatan menjadi kendala di Pulau Tunda. Keberadaan sampah diduga berasal dari daratan utama yang terbawa oleh angin muson timur dan barat (Maharani et al, 2020). Tabel 3.…”
