Abstract

Bed sediment characteristics and distribution is one of the important parameters in determining the management plan and utilization of estuarine and coastal waters.  The objective of this study was to analyze sediment distribution and determine dominant oceanographic factors controlling the distribution of bed sediment in the river estuary and coastal sea of Malili. Sediment samples were collected using a grab sampler at ten stations, namely four stations in the river estuary and six stations in the adjacent coastal sea for grain size and sediment organic content analysis. The results showed that the bed sediment along the river estuary consisted of silt, very fine sand, fine sand, and medium sand with organic content varying from 1.31 to 7.18 %. In the coastal sea, bed sediment was dominated by silt with a higher organic content of 2.25 - 7.31%

Abstract

HABs were types of phytoplankton considered dangerous in the sea. Its appearance was triggered by an increase in nutrients and the presence of physical and chemical factors in the optimal conditions to support its growth. For that reason, research on the analysis of the causes of the emergence of HABs in the coastal waters of Makassar has been carried out. The implementation is carried out from March to June 2017 using non-experimental methods. The results showed that there were seven types of HABs, such as Protoperidinium, Gymnodinium, Ceratium, Prorocentrum, Gyrodinium, Gonyaulax, and Dinophysis. That types from the Dinophyceae Class. The appearance of the types of HABs was due to the influence of temperature with the relationship were very strong and positive.

Abstract

Marine debris is defined as material that is solid, persistent, manufactured or processed, and deliberately or not-deliberately left in the marine environment. Marine debris comes in many shapes and forms, ranging in size from microscopic microplastics to large vessels. Marine debris is a big and growing global problem, pose threats to marine life sustainability. Plastic is a major component of marine debris, and single-use packaging accounts for an increasing part of the global marine debris load. Research on marine debris was conducted on coastal areas and Small Island of South Sulawesi destined for local tourism, i.e., Karama beach, Bodia beach and Mandi beach (Galesong, Takalar District), Tanjung Bayang beach, Akkarena beach and Lae-lae island/also known as Bob beach (Makassar City). This research was aimed at identifying marine debris according to its types, size, and mass. Debris was collected in a 25 x 60 m transect with direction 30 m towards land and waters, respectively, with 3 replication transects at every location, whilst collections of debris were conducted during low and high tides. Current (direction and speed) and waves (incoming direction and height) were also measured as supporting parameters. Surrounding sampling location characteristics were also recorded. The result showed that Karama beach is found with highest total marine debris mass in Takalar (36.44 kg), whilst in Makassar, the Lae-lae island was found to be the highest with debris mass (43.22 kg). Plastic was predominant debris at all sampling locations with percentages of 62.7 – 86.6%. Lastly, the predominant size was macro-debris (25-100 cm).
