Abstract
Marine debris now considered a global concern, is any solid created by human activity that is either purposely or mistakenly thrown into the coastal environment, directly or indirectly. The presence of marine debris may have a wide range of detrimental effects on coastal ecosystems and the environment, including in the Kulon Progo coastal area of Yogyakarta. Unfortunately, no research on marine debris has been conducted in Kulon Progo Regency so far. As a result, the purpose of this study is to define the marine debris characteristics in Yogyakarta’s Kulon Progo coastal area, as well as to analyze tidal influences on marine debris in the study area. Tidal data were obtained from the Tidal Station Data Information System and the Indonesian Geospatial Reference System, Geospatial Information Agency (BIG). Admiralty methods were used to identify the tidal type based on the 29 days of data every 1 h during the last year. Marine debris samples were collected using the transect and simple random sampling method for each beach during different tide conditions. Furthermore, the statistical method of one-way ANOVA was used to obtain the relationship between tidal and marine debris data. The results show that the Congot and Pasir Kadilangu Beaches tides are a mixed tide prevailing semi-diurnal type (1.50 ≥ F > 0.25). Compared to Pasir Kadilangu Beach, Congot Beach has more macro- and meso-sized marine debris during low and high tides, where plastic debris dominates both beaches. In more detail, during the high tide, the mass and amount of marine debris is more significant than during the low tide on both beaches. This phenomenon is supported by the statistical results with a P-value < 0.05. It means that tidal fluctuations and characteristics of marine debris have a substantial connection.
期刊介绍：
The Journal of Coastal Conservation is a scientific journal for the dissemination of both theoretical and applied research on integrated and sustainable management of the terrestrial, coastal and marine environmental interface.
A thorough understanding of both the physical and the human sciences is important to the study of the spatial patterns and processes observed in terrestrial, coastal and marine systems set in the context of past, present and future social and economic developments. This includes multidisciplinary and integrated knowledge and understanding of: physical geography, coastal geomorphology, sediment dynamics, hydrodynamics, soil science, hydrology, plant and animal ecology, vegetation science, biogeography, landscape ecology, recreation and tourism studies, urban and human ecology, coastal engineering and spatial planning, coastal zone management, and marine resource management.
