The mechanism of temporary upwelling and downwelling in the southern coast off Makassar Strait, Indonesia is determined not only by the wind-driven coastal during southeast monsoon (SEM) and northwest monsoon (NWM) but also by meeting of two current systems based on previous research. During SEM, water mass of the Flores Sea in eastern area meets the throughflow water coming from northern of Makassar Strait and flow together to Java Sea and this causes upwelling occur. But during NWM, water mass of the Java Sea western area meets the through flow water and flow together to southern cost of Celebes Island and causes downwelling occur. The first mechanism is well proven but the second one need more investigation.Twenty years of data result obtained from numerical simulation over the Makassar Strait and adjacent waters are used to describe the seasonal characteristic and mechanism of upwelling in this region. The 3D baroclinic ROMS (Regional Ocean Model System) from Rutgers version was simulated from 1995 to 2014.The climatological results show the existing of upwelling and downwelling clearly identified by the decreasing or increasing of sea surface temperature ± 2ºC and also increasing or decreasing of surface salinity ±0.5 Psu compared by surrounding waters. The evidence of upwelling starts on June, maximum intensity in August and disappears on September following the easterly wind during southeast monsoon. But downwelling start on December, maximum intensity in January and disappears on February. The mixed layer depth becomes shallow and there is an uplift water from the thermocline to the surface at the upwelling occur, but when downwelling occur the mixed layer depth becomes deeper. The instability of water column was detected from the Brunt-Väisälä frequency (N2) and Richarson number (Ri). By calculating the vorticity and investigate the current circulation we detect the eddy formation in southern part of the Celebes Island at Java Sea and Flores Sea and suggested due to the meeting of current system. We found the Ekman transport is moving to the southern direction offshore of Celebes Island and produces the upwelling during SEM. But when NWM occur, Ekman transport is moving to the northern direction from offshore to the Celebes Island and produce downwelling.

Kendal District coastal and marine areas have considerable fishery potential. The potential of these fisheries can be explored well by taking into account several supporting factors. One of the factors that influence the level of fish existence is the condition of water fertility. The parameter used to determine the level of water fertility is to determine the chlorophyll-a content produced by phytoplankton. The development of remote sensing technology makes it possible to detect the presence of chlorophyll-a in waters with a large coverage and low cost. This study aims to identify the value of concentration and distribution of chlorophyll-a by using satellite landsat 8 imagery in four seasonal conditions, namely the west to east transition season, east season, east to west transition season and west season. The transition from West to East the minimum value of chlorophyll-a concentration is 1,106 mg / m3 and the maximum value is 2,700 mg / m3. East to West transition season has a minimum value of chlorophyll-a concentration of 1,539 mg / m3 and a maximum value of 2,700 mg / m3. The East Season has the same minimum and maximum values as the transition season from West to East but the amount of distribution differs, the West Season has a minimum value of chlorophyll-a concentration in this season of 1,318 mg / m3 and the maximum value of 2,700 mg /m3.

Grouper fish is the most exploited commodity for coral fisheries. The controversy that occurred between researchers regarding the identification of fish species is a problem that is quite alarming. Identification using morphometric measurements, shape and color or morphology is considered still not accurate in determining the fish species. The DNA barcoding method uses COI markers by tracing the nucleotide bases to determine which species of biota have advantages in species identification. This study aims to identify grouper fish species in the traditional Muara angke fish market by using morphological methods and DNA barcoding. The identification results obtained from the morphological methods (shape, color and morphometrics) that the sample species are white-tailed grouper fish (Epinephelus areolatus) by looking at morphological characteristics, namely the white lines on the caudal fins and brown spots on the body. Identification using the DNA Barcoding method using the COI markers showed that the fish samples were 95% similar to E. areolatus.
