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

Surface chlorophyll-a (Chl-a) distribution have been analyzed with seasonal variation during southeast monsoon in southern part of Makassar Strait and Flores Sea. Satellite data of Landsat-8 is applied to this study to formulate the distribution of chlorophyll concentration during monsoonal wind period. The distribution of chlorophyll concentration was normally peaked condition in August during southeast monsoon. Satellite data showed that a slowdown in the rise of the distribution of chlorophyll in September with a lower concentration than normal is likely due to a weakening the strength of southeast trade winds during June – July – August 2016. Further analysis shows that the southern part of the Makassar strait is likely occurrence of upwelling characterized by increase in surface chlorophyll concentrations were identified as the potential area of fishing ground.

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.

Abstract

This study aims to describe the relationship between the upwelling area and the ZPPI area of ​​skipjack tuna using the Generalized Additive Model (GAM) method and to map out the distribution pattern of skipjack in Barru waters, Makassar Strait. The research was conducted in November and December 2020, located in Barru waters, Makassar Strait. The research method used two methods by collecting primary data in the form of catches by following the purse seine fishing operation in Barru and secondary data in the form of satellite imagery data on sea surface temperature and chlorophyll-a. The data were analyzed using the GAM and upwelling area analysis. The upwelling area was obtained from the combination of the referred values of the two parameters. The results showed that sea surface temperature parameters had a significant effect on the catch of skipjack tuna with favored range of 28.5 - 29.7 oC.  Preferred chlorophyll-a ranged from 0.15 to 0.23 mg m-3. We found that the upwelling event in the Flores sea does not have a direct effect on the distribution pattern of skipjack tuna, there is probably a time lag required after upwelling in which in turn has an impact on the distribution of skipjack tuna in the southern Malassar Strait.

Abstract

Satellite remote sensing provides systematically important information on oceanographic signatures. Sea surface temperature (SST) and chlorophyll-a concentration (Chl-a) obtained from Aqua/ Moderate Resolution Imaging Spectro-radiometer (MODIS) data together with skipjack fishing data during January-June were applied to assess the distribution pattern of skipjack tuna in the Bone Gulf, Indonesia. Geographic information system techniques were employed to map out the potential fishing zone generated from the Cobb Douglass model. The fish distribution pattern was produced by the movement of the Gravity Center of the potential fishing ground. Results expressed that the most potential catch per unit efforts (fish/trip) associated with the areas where a combination of optimum SST and chlorophyll-a concentration ranged was found. The center of skipjack potential fishing zones developed in January-February along with the western regions in the Bone Gulf and moved to the northern side during March and April, and subsequently migrated to the south in May –June. We found that skipjack tuna showed a clockwise movement pattern throughout the Bone Gulf during the first semester period (January-June). Therefore, the potential fishing zones suggest corresponding to the movement of skipjack concentration, which may link with prey upon by skipjack.

Abstract

This study was aimed to determine the water quality and seaweed growth and the relationship between  oceanographic parameters and the growth of seaweed Eucheuma cottonii. This research was carried out from June-July 2021 at a seaweed cultivation location in Old Takalar, Mappakasunggu District, Takalar Regency. The seaweed cultivation method used is the longline method placed at three cultivation sites. Oceanographic parameters of physicochemical waters measured were temperature, salinity, pH, brightness, depth, current velocity, tides, nitrate, phosphate and dissolved oxygen. For the measurement of the growth of E. cottonii seaweed, the absolute growth was measured using One Way Anova analysis to determine differences in seaweed growth at each station of E. cottonii cultivation location. The correlation between oceanographic parameters and the growth of E. cottonii seaweed was analyzed using a correlation test. The results showed that the water quality at the cultivation site was within a reasonable range for seaweed cultivation in Old Takalar. The results of One Way Anova showed that there were significant differences in seaweed growth at each station where E. cottonii was cultivated. The results of the correlation test showed that the oceanographic parameters of the waters were very strongly correlated with the growth of E. cottonii seaweed, namely temperature, brightness, and depth.

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

Seaweed cultivation activities in Jeneponto Regency have been practised for a long time and have become the main livelihood for most of the Mallasoro Bay community. In cultivating seaweed, obstacles often arise in the form of failures experienced by seaweed farmers or poor-quality yields. This study was aimed to develop alternative planting calendars for Eucheuma sp. in Mallasoro Bay, Jeneponto Regency based on sea surface temperature and distribution of chlorophyll-a obtained from Landsat-8 imagery. Image Processing Sea Surface Temperature and Chlorophyll-a were processed using ENVI 4.8 AND 5.3 software, the satellite images used were clean and without cloud disturbance. In this study, data analysis was carried out descriptively. The water temperature that is good for seaweed growth is 27-30˚C, for Mallasoro Bay Sea Surface Temperature which is suitable for seaweed cultivation, namely April, May, June, July, August, September, October and November. While the classification is based on the criteria for chlorophyll-a trophic status in marine waters, namely the range < 1 mg/L is classified as Oligotrophic, ≥ 1–3 mg/L is classified as Mesotrophic, ≥ 3–5 mg/L is classified as Eutrophic, and > 5 mg/L is classified as Hypertrophic. , from the results of image analysis for the distribution of chlorophyll-a in Mallasoro Bay, it shows that Mallasoro Bay is at the Mesotrophic level throughout the year or the fertility level of the waters is quite fertile because it is in the range of ≥ 1–3 mg/L. so that a seaweed planting calendar can be obtained in Mallasoro Bay, namely in January, February and December, preparation of tools such as cleaning and repair of seaweed planting tools can be carried out, then at the end of March, the end of May, the end of July and the end of September, the procurement of seaweed seeds is carried out. , in early April, early June, early August, and early October, seaweed seeds can be spread, then in mid-May, mid-July, mid-September, and mid-November, harvesting can be carried out, so that seaweed cultivation can be carried out 4 times in one year. cycle.
