Abstract

Clams have a planktonic period which is sensitive to metal pollutants in the waters. The natural concentration of cadmium (Cd) is relatively low in marine waters but may increase with increasing anthropogenic activity on land that may be lethal to organisms, especially in the sensitive larval stages. The purpose of this study was to analyze the values of 24h-LC50, NOEC (No Observed Effect Concentration), LOEC (Lowest Observed Effect Concentration) and MATC (Maximum Acceptable Toxicant Concentration) along with the impact of acute Cd toxicity on mortality and morphological changes of Tridacna squamosa veliger. The toxicity test used was an acute toxicity test with a static method (4 replications). Acute toxicity tests were performed on veliger phase larvae with short-term exposure (24 hours) on various Cd concentrations ie., 0.1 mg/L, 1 mg/L, 2.5 mg/L, 5 mg/L and 10 mg/L . The 24h-LC50 value was calculated using the Trimmed Spearman-Karber application version 4.1, and the LOEC and NOEC values were analyzed using the Dunnet test. Results showed that the 24h-LC50 value of Cd applied to Tridacna squamosa veliger was 2.12 mg/L, whereas the NOEC, LOEC, and MATC values were 1 mg/L, 2.5 mg/L, 1.581 mg/L respectively.  Mortalities were observed with increasing Cd concentrations. It was also shown a decreasing number of zooxanthellae, damaged in mantle tissue and shells, changes in shell color, released of mantle tissue from the shell with increasing Cd concentrations.

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).

Abstract

To support the efforts of the Indonesian government in managing marine debris that has a broad potential negative impact in various aspects, beach debris monitoring activities are urgently required in various locations. This research was carried out from June to August 2018 in the west coast region, on Labuange beach, Barru Regency, South Sulawesi Province, Indonesia, which was exposed by the Indonesian Through-Flow. The study aimed to determine the amount, weight and composition of marine debris on Labuange beach.  Marine debris was sampled from a permanent line transect with an area of 150 m2 (three replications). Samples were then cleaned, sorted, counted, and weighed. The average amount of marine debris was 5.98 + 2.13 items/m2 per month, with a total weight was 138.69 ± 91.32 g/m2 per month. Plastic and rubber category dominated every sampling period in the location. The abundance of marine debris, both regarding quantity and weight, fluctuated in high amount during the sampling period, which indicated the magnitude of the role of oceanographic factors, including the direction of waves, and lack of community awareness on marine debris impacts and management. The great amount and weight of marine debris and the type of waste, which was dominated by plastic and rubber is a potential threat to humans, marine biota, and the local or global environment.

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

The biodiversity of the Tiworo Strait Conservation Area (KKLD) was highly potential to be developed. However, in recent years, potential utilization has begun to lead to environmental destruction due to the use of destructive fishing gear. Therefore, biophysical studies were needed to give an overview and outlook about the area in order to provide information on the condition of coral reefs, reef fish, mangrove, sea grass, scare/endemic biota and socioeconomic conditions as well as the cause of aquatic ecosystems destruction. The method used to collect the data in the field is by undertaking observation, interview, and literature study method. Observation of coral cover and benthos used was by Point Intercept Transect (PIT) method while for the reef fish, the method used was a visual water census (UVC). Quadratic transect method was used for observation of sea grass and mangrove ecosystem. Meanwhile, the socio-economic condition is done by interview survey technique. The observation result shows the coral condition of the Tiworo Straits KKLD was in the medium category with the mean percentage of live coral of 46%. The lowest percentage of live coral was located at Station 1 of Mandike Island (18%), and the highest was at the Indo Island Station (76%), which is categorized as very good. The number of individual reef fish is 1.217 individuals / m2, and benthos type that dominates was sea urchin. The highest density of mangrove trees was 4000 trees/ha and the lowest was 200 trees/ha. The types of sea grasses observed were Thallasia hemprichi and Ehalus acroides. People, in general, have a livelihood as a fisherman with gill net fishing gear and fishing platform.

Abstract

In environmental impact assessment of coal plant, it is essential to determine the radius impact. This information can be used to determine the impacted area, which will significantly receive the pollution emitted from the stack for years. In this study, we use the American Meteorological Society - Environmental Protection Agency Regulatory Model (AERMOD) model, which is a regulated model in the USA and other countries. Five years hourly meteorological data for feeding AERMET model was obtained from MM5 re-analysis data. Terrain data was extracted from the SRTM30 satellite image and converted into DEM. The parameter to be considered in this study is Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), and Total Suspended Particle (TSP). The calculation shows that the pollutions tend to disperse in the south direction by the wind direction. NO2 is more disperse than SO2 and TSP.  Calculation of impact radius indicates that concentration of all pollutants in annual average is below the national standard. For the case of the highest one hour average gives the radius impact of 18 km for NO2 and 9 km for SO2.  For the case of the highest 24 hours, only NO2 gives value beyond the standard with an impact radius of 4.5 km.  Calculation of TSP indicates that concentration is below the standard in all cases. The maximum concentration of all pollutants is detected 3 km south of the stack.

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

Plastics become debris in the ocean that can be broken down into tiny particles of micro size (<5 mm) and scattered into columns to the bottom of the water. Its very small size makes it easily accessible to various aquatic organisms, such as plankton, crustacean, and mussel. There have been many studies use mussel as a bioindicator for microplastic pollution but no one has observed the effect of microplastic exposure to mussel mortality. The aim of study was to examine the effect of microplastic on mussel mortality. Green mussels were collected from Mandalle Waters, Pangkep Regency (Pangkajene Kepualauan) then were exposed to microplastic polyethylene originating from shieving of scrub soap. The exposure was carried out for 7 days with microplastic concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. Statistical test results showed the treatment B and C were not significantly different, but the two treatment were significantly different from treatment A. The percentage of green mussel mortality during the experiment increased with increasing microplastic concentrations with the percentage of mortality exceeding 80% at treatment C.

Abstract

Sulawesi is an island famous for its biodiversity, including many endemic species. In particular, Sulawesi has the highest number of gobies in the world, including species with potential as food and/or ornamental fishes. The exploration of freshwater ichthyofauna is important in the context of Indonesian and global biodiversity. This research aimed to identify gobies found in the Luwuk Banggai area of Central Sulawesi, as a contribution to the exploration of Indonesian ichthyofaunal biodiversity. Gobies were sampled from January to March 2019 in the Biak and Koyoan Rivers. The sampled fish were measured and identified based on morphological characteristics. A total of 52 specimens were collected, and identified as belonging to 17 species within two families, the Gobiidae and Eleotridae. Gobies from the Koyoan River comprised 32 specimens from 8 species, while 20 specimens belonging to species were found in the Biak River. Only two species were found in both rivers: Stiphodon semoni and Sicyopterus lagocephalus. These results augment the body of knowledge regarding the presence and distribution of gobies in Indonesia

Abstract

This study aims to determine the level of land suitability and the area of Eucheuma cottonii in Pasiea waters, to know the dynamics and correlation of oceanographic parameters towards the growth of E. cottonii seaweed. This research was conducted in August-October 2018 in the area of seaweed cultivation in Pasiea waters. The observation station consisted of six stations located in the area of seaweed cultivation. Oceanographic parameters dynamics were measured by oceanographic parameters measured which significantly affected the growth of seaweed species E. cottonii in the form of temperature, salinity, brightness, depth of flow, current velocity, nitrate, and phosphate has been mentioned before which wasthen overlaid on the map maker application to produce a map of the suitability level of E. cottonii seaweed cultivation in Pasiea waters. The results of the spatial analysis showed that the level of Pasiea waters suitability based on oceanographic parameters was in the less suitable category covering 1410 ha and did not match 1 Ha, whereas based on the daily growth rate of E. cottonii the overall research locations were in the excellent category of 1411 ha. The dynamics of oceanographic parameters were still within the range that can be tolerated for the growth of E. cottonii with parameters that correlate to the daily growth rate of salinity, brightness, phosphate, and nitrate.
