Oil spilled in the marine ecosystem may be induced by some sources which alter over time and location. Oil leakage from offshore oil drilling, underwater oil pipeline leakage, etc., are the possible source of oil spill pollution. Marine pollution generated by oil spilling occurred in Padang City in 2017. Palm Fatty Acid Distillate (PFAD) spilled within Bayur Bay Harbor due to a leaking storage tank. As much as 50 tons of PFAD overflowed and commenced to pollute Bayur coastal bay. This study aimed to determine the distribution pattern of oil spills throughout the Bayur Bay based on a hydrodynamical model. We employed some oceanographic data and PFAD characteristics obtained directly from survey results. We simulated the particle tracking model for 30 days since the PFAD spilled within the port. The model developed applied the Least Square method to analyze tidal data and a flexible mesh as a model basis, while the governing equation used is Navier Stoke discrete. During a month of simulation, the dominant particles' distribution is still spinning around the Bayur Bay due to the weak current characteristics with the magnitude ranging from 0.02-0.06 m/s. The lighter PFAD particle mass tended to move faster throughout the bay and settled in the coastal area. It will pollute the coastal system even though it is going to be decomposed chemically in the sediment.

“…Estimating the level of microplastic contamination in a certain water area is carried out by taking water samples from the waters and then analyzed. The forms of microplastic that are commonly found in water areas are in the form of fibers, fragments, and filaments (Fitriyah et al, 2022), fibers and pellets, fragments, filaments, films, foams, and granules (Purba et al, 2019). The color of the microplastic varies from transparent, blue, black, yellow, and red filaments (Fitriyah et al, 2022).…”

Mismanaged plastic wastes still become main environmental problem in many countries. It also believed as the root of many environmental problem today faced by both advanced and develop countries, like Indonesia. Microplastics polluted the aquatic environment of Indonesia today mainly come from mismanaged plastic wastes (secondary), but both of the primary and secondary microplastics exist in Indonesian water. This paper reviews microplastic pollution in Indonesian water focused on two main topics, namely the characteristics of microplastics in Indonesian waters and their sources and effects of the presence of microplastics on aquatic organisms. This article was compiled using secondary data consisting of various data and papers, materials obtained from various sources of relevant and reliable official publications that are closely related to the microplastic pollution in Indonesian waters. These findings were then analyzed in an explanatory descriptive manner to provide an overview of characteristics and the sources of microplastics in Indonesian waters and how microplastics affect aquatic ecosystems. It is hoped that this will provide an opportunity to address this issue more effectively.

“…Dengan perkembangan yang semakin jelas di perairan pantai Kabupaten Karangasem, khususnya di perairan sekitar Tanjung Melanting. Sesuai penemuan Adibhusana et al, (2016) dan Purba et al, (2019), contoh pengembangan molekul bisa muncul dari adanya pengaruhi perkembangan aliran laut, yang menunjukkan contoh hidrodinamika yang mengalir, serta oleh efek angin pada aliran ini. Terlepas dari pengaruh arus, hidrodinamika mengalir yang terjadi membuat partikel-partikel tersebut terus bergerak melingkar misalnya di dalam air (Gambar 8).…”

The issue of marine waste has become a global concern due to its impact on polluted biological systems. This occurs because, many individuals still believe that the ocean can handle waste on its own, so they toss trash into the waterway, ending th seas. There has been some research on marine flotsam and jetsam, but little research has been conducted on the distribution of marine debris and jetsam in the waters and along the coast of Badung Strait. This investigation seeks to determine the movement of marine debris and jetsam in the seas and along the coast of the Badung strait during the autumn season. The Limited Volume Coastal Sea Demonstrate (FVCOM) method induces 3D current patterns and particle dispersion patterns derived from 3D Lagrangian Molecule Simulations. As a result of the development of wind and currents, the way of flotsam and jetsam dispersion in the Badung Strait during the westerly season was primarily eastward. The pattern of flotsam and jetsam dispersion within the Badung Strait during the western season was primarily eastward due to the development of winds and currents. Additionally, marine flotsam and jetsam particles move along Badung Strait’s coastline to the coastline of Nusa Penida. In addition, Karangasem Rule, specifically the waters of Melanting Cape and Bugbug Cape, is home to an intriguing area for trash accumulation. This occurs because the shape of the shoreline, which is typically depressed, can trap flotsam and jetsam carried by water streams. In addition, the longer waste particles remain in the water, the more likely they are to be consumed by marine biota that cannot differentiate between their prey and marine waste, particularly filter-feeding marin animal
