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

Marginal coral reefs are located in a limited aquatic environment, causing coral organisms to live under threat and only certain species of coral are able to survive. Porites lutea is one species of coral that is able to live in normal and marginal coral reef conditions. The purpose of this study is to determine the ecology of Porites lutea, the physiological ability of Porites lutea's Productivity (P) and Respiration (R), coral reef habitat conditions and environmental factors that affect the distribution of Porites luteal in normal and marginal locations. This study used the belt transect method, measurement of coral colony volume, physiological productivity (P) and respiration (R), transect picture for substrate cover and coral reef conditions and CTD to measure environmental indicators such as temperature, salinity, turbidity, chlorophyll and DO. The results shows that the density of Porites coral is higher at normal coral reef locations (Pak Kasim), the highest volume range is 25-100 cm3, with the largest size in the 451-475 cm3 class. P/R values ​​is higher at normal coral reef sites, especially in reef slope areas. Coral reef habitat cover is dominated by abiotic components with poor coral reef conditions in marginal and normal environments. Water temperature was significantly different (P=0.039) between two normal and marginal locations with a range of 27.08 - 27.51 oC, Salinity was significantly different (P=0.145) with a salinity 33.44ppt at normal locations and 32.88 ppt at marginal locations. The chlorophyll and oxygen number was not significantly different between the two locations, the range of chlorophyll 0.03 – 0.15 mg/L and oxygen 2.49 – 5.23 mg/L. The turbidity factor was significantly different between locations (P=4.86E-07) where the marginal location in Sample was more turbid than the normal location in Pak Kasim. This study shows that there are differences between normal and marginal waters in environmental conditions and physiological reactions of Porites lutea, but this coral is able to survive to show their resilience to environmental stresses.  Keywords: Coral physio-ecology, Porites lutea, P/R ratio, marginal coral reefs.

Abstract

Kabung Island is an island located in Bengkayang Regency, West Kalimantan, Indonesia. The characteristics of these waters are sandy, muddy and muddy sand. This type of water is compatible with the life of Gastropods and Bivalves. Both of them play an important role in an ecosystem because of their ability as a filter feeder that filters dissolved substances in the water, for a source of food for their survival. The abundance and diversity of molluscs are highly dependent on the conditions of the aquatic environment, such as substrate type, pH, turbidity, temperature, salinity and dissolved oxygen, availability of food, pollutants, predators and competitors. This study was aims to assess the diversity and abundance of molluscs on the Kabung island. The results on this research show that the highest diversity index is 1.94 which means that it is in moderate condition. The evenness index and dominance index values found to show a value of 0.88 which means high evenness so that a dominance value of 0.45 means that there are no molluscs that dominate on the Kabung island. Keywords: Abundance, Bivalves, Diversity, Gastropods, Mollusca.

Abstract

Macroalgae or known as seaweed is one of the potential resources and is responsible for primary productivity in marine waters. Macroalgae plays an important role in marine ecosystems, provides food, oxygen, and habitat for several types of marine biota. Moreover, macroalgae have been reported as renewable resources in marine environment and widely used in various fields. The biodiversity and abundance of macroalgae are strongly influenced by aquatic environmental factors. Lemukutan Island is the largest inhabited island located in Bengkayang Regency, West Kalimantan and has the potential natural resources, including macroalgae. This Island can become a center for producing macroalgae that can be used to meet food needs both locally and domestically. The main objective of this study were to determine the community structure of macroalgae and the condition of the environmental physico-chemical parameters. The sampling locations were carried out in-situ at three stations and the determination of the sampling site was done by purposive random sampling method, by selecting an area based on the presence of macroalgae. The sampling of macroalgae was carried out using a quadratic transect with size of 10x10 m2 and the water quality parameters were measured using the AZ 8603 of WQC instrument. The study found 6 genera of macroalgae, such as Caulerpa, Halimeda, Padina, Turbinaria, Sargassum, and Gracillaria. Among the identified macroalgae, Phaeophyceae have the highest per cent contribution (50%), and Padina had the highest abundance (29.84 ind/m2). Lemukutan Island waters had a moderate level of diversity, high macroalgae uniformity, and dominance index in the low category. The aquaatic environmental factors influenced the abundance of macroalgae in Lemukutan Island waters.

Abstract

The presence of high-resolution satellite imagery on Google Earth provides an opportunity for the availability of maps that can be used as a reference for accurate coordinates. Google Earth has been developed to contain high-resolution images, but it warns users about the accuracy of the data regarding the coordinates of the objects covered. Coordinate inaccuracies have the potential to cause problems when used for navigational purposes, or in technical tasks requiring high accuracy such as surveying and mapping applications. Despite these warnings, users are often forced to refer to Google Earth as a reliable data source due to the absence of other data sources. The purpose of this study is to evaluate the accuracy of Google Earth's horizontal coordinates and determine the maximum map scale that can be made based on coordinate data from Google Earth on the coverage of small islands in the Makassar City area. The method used is to compare the object coordinate obtained from Google Earth and the coordinate measured in the field at the same object point. The calculation results show the RMSEH is 2.49 meters and the horizontal accuracy is 4.28 meters. These results indicate that the horizontal coordinates on Google Earth can be referenced to produce a map with a maximum scale of 1: 10,000.

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.
