Abstract

Coral reefs and seagrass are natural fortress for small islands from waves and ocean currents. The spatial distribution of these benthic substrate should be known and monitored regularly. This study aims were to map existing benthic substrates on the reef flat of Bontosua Island, determine the spatial composition and develop index ratio. Benthic substrates were surveyed using geotagging technique. Their distribution were estimate using Quickbird image that was rectified and classified using ISOcluster method and validate by 240 selected photos. The seagrass were surveyed at 8 stasions to record percent cover and species composition. Depth profiles were track along 10 reef flat line segment. Bontosua Island has an elongated shape from South to Northwest. This study had produced a benthic substrate distribution map with thematic accuracy 76%. Total area able to map were 54.2 hectares. About 43% benthic substrates at Bontosua were mixture of coral rubble, seagrass and algae, 20% was mixture of rubble and algae, 16% dominated by seagrass, 13% mixture of sand and seagrass and 8% substrate were dominated by live coral. There were eight seagrass species found with average percent cover 37.2 ± 12.5 percent. The spatial ratio of live coral, seagrass and mixed substrate for West side reef flat was 2:20:49 and 1:9:9 for East side. This indicate that the distribution of benthic substrates on the West side is much wider than on the East side. This approach potentially applied to study the relationship between benthic substrate composition and the deformation of small islands.

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

Seagrass distribution is influenced by many factors, including sediment characteristics. This study aims to determine the distribution of seagrass based on their sediment characteristics. Observations and sampling were carried out in the waters of the Puntondo Bay, Takalar Regency. This study observed the cover and density of seagrass species, water depth, water transparency, sediment’s total organic matter and size of sediment grains. There were five species of seagrass found in the area, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis and Syringodium isoetifolium with sediment types of medium sand and coarse sand. Results of the regression analysis showed that the relationship between sediment particle size and seagrass density with the  highest coeficient determination (R2=0,3346) was in seagrass Cymodocea rotundata, whereas the lowest was in  Syringodium isoetifolium. Keywords: Seagrass, Puntondo, aters, Sediment grain size, Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis, Syringodium isoetifolium.

Abstract

Marine debris may become a serious threat because of the increasing in its quantity every day, especially in marine areas around the world. The purpose of this study was to identify the amount, weight, and type of marine debris and to determine the abundance based on the amount and weight present in the coastal area on Kodingareng Lompo Island, Makassar City. This research was carried out during the ebb of the east monsoon period, i.e., in June 2021. The most common types of waste found in the three observation locations were plastic waste. The abundance of waste based on the amount is most commonly found at station 2, which is located near a residential area, so that most of the waste at the station is household waste. Meanwhile, the greatest abundance of weight was also observed at station 3 which has the widest intertidal area and the majority of the waste there came from a type of cloth which was larger than other wastes. Station 3 also has a faster flow rate than the other stations. The existing waste facilities on Kodingareng Lompo Island in the form of garbage motorbikes and Garbage Banks in general have not been effective. Several factors that can also worsen, i.e., lack of understanding, low awareness, and laziness of the community in managing their waste, people prefer to throw garbage into the sea, so the accumulation of marine waste in the coastal area of Kodingareng Lompo Island may have a negative impact in various fields of life.

Abstract

Characteristics and distribution of bottom sediment is one of the important parameters in determining the management plan and land use in coastal areas. The purpose of this study was to determine the condition of the distribution of bottom sediments and to compare the changes that occurred in the distribution of bottom sediment before and after the reclamation of the Center Point of Indonesia (CPI) in Makassar City. Sediment sampling was carried out using a grab sampler at four stations, namely stastions on the island adjacent to the reclamation area and two other stations in the water around the reclamation area. The results showed that the bottom sediment in the waters around the reclamation area consisted of coarse sand and medium sand with an organic matter content of 14.92% in the sediment. On the islands adjacent to the reclamation area, the bottom sediments are move varied, consisting of coarse sand, medium sand and fine sand with lower organic matter content of 4.92% to 5.38%.

Abstract

Benthos are invertebrate animals that live at the bottom of the waters. One biota that can be used as a biological parameter in determining the quality of a waters is macrozoobenthos. The waters around the Center Point of Indonesia (CPI) are one of the waters that have received a lot of additional organic matter and other pollutant materials through the estuaries of the canals that flow into the waters of Losari Beach. The study was conducted by sampling macrozoobenthos at each station using Ejkman Grab at each station 3 times sampling then sieved using a benthos sieve measuring 1 mm. In addition, measurements of environmental factors were carried out at each station with 3 replications directly in the field and analyzed in the laboratory. The results of the macrozoobenthos sampling study obtained 4 macrozoobenthos classes found at the study site, namely the Gastropod Class (4 species), the Crustacea Class, the Ophiuroidea Class, and the Oligochaeta Class each 1 species. The highest diversity and abundance of macrozoobenthos was found at Station 6 which is suspected because this station has a sandy sediment texture and sediment DOM content and high concentrations of water solubility of oxygen which support the life of makzoobenthos. Macrozoobenthos diversity at the study site (waters around the Center Point of Indonesia) is low with a diversity index (H') value of 0.00 - 0.16. The high abundance of makzoobenthos at Station 5 and Station 6 is characterized by high current velocity, sediment DOM and high oxygen concentration.

Abstract

Seaweed cultivation is an alternative community livelihood that potentially helping to reduce pressure on coral reefs in the area of Raja Ampat Archipelago. This study was aimed to conduct an oceanographic analysis of the waters of Meosbekwan Island (Raja Ampat Regency) for the suitability of seaweed cultivation. Oceanographic data collection was carried out at three points (M1, M2, and M3) on the western side of Meosbekwan Island. Analysis of suitability for aquaculture was initiated with an analysis of key parameters, i.e., depth, protection and shipping traffic. The suitability analysis was followed by an analysis of the oceanographic parameters of the waters by weighting them using a ranking system. Furthermore, the final stage of suitability analysis was to evaluate the feasibility level of seaweed cultivation. The results showed that the depth of the waters on the western side of Meosbekwan Island ranged from 1.3 m – 5.8 m with an average depth of 1.5 m in the south (M1), 2.2 m in the middle (M2), and 3.9 m to the north (M3). Wave height during the study ranged from 0.1 – 0.3 m with an average value of 0.25 m at all points. The velocity of the water currents ranged from 0.08 – 0.25 m/s. The salinity of the waters was relatively homogeneous (30 - 31 o/oo). Water temperature also has small and relatively homogeneous variations with a range of 30 - 31˚C. The brightness of the waters ranged from 2.5 – 3.5 m. The bottom of the waters on the west side of Meosbekwan Island generally consists of coarse sand, rubble, and seagrass vegetation Enhalus acoroides and Cymodocea sp. In general, the oceanographic conditions of the waters are suitable for the life and growth of seaweed. The results of the location suitability evaluation indicated that the waters on the western side of Meosbekwan Island were technically feasible to serve as a location for seaweed cultivation.
