Abstract

Sediment is a collection of particles that come from weathering both soil and rock, biological and an anthropogenic process. Sediment flows from upstream to downstream areas. Topographic conditions are one of teh factors in sedimen distribution. The topography in the Wonorejo area tends to be low because it is located in a coastal area. The purpose of this study is to determine the effects of topographic changes in Wonorejo on the distribution of sediments in the area. The method used in this study is descriptive method by collecting data including primary data and secondary data. The primary data used are Landsat 7 and Landsat 8 satellite imagery, while the secondary data used is in the form of Surabaya village administration map data, Surabaya DEM data and Indonesian SHP data. Data processing was performed using ArcGIS 10.3 software. The results indicated that the topographic conditions of the region did not have a significant influence on the distribution of sediments in the Wonorejo area. The distribution of sediment in those area was more influenced by hydro-oceanographic factors such as currents, tides and waves. Other factors that influence are anthropogenic factors such as development and land conversion.

Abstract

Oil pollution in the waters is one of the factors that affect the abundance of fhytoplankton, especially the diatom. The waters of Lalang Strait, Mengkapan Village, are used as international shipping lanes and industrial areas. This study aims to analyze the total oil content, calculate the abundance of planktonic diatoms, and explain the relationship between the total oil content and the abundance of planktonic diatoms carried out in the Lalang Strait waters, Mengkapan Village, Siak Regency, Riau Province. This research uses survey method. Station 1 is near Tanjung Buton Port, station 2 is in the mangrove ecotourism area, and station 3 is in the fishing port and near the settlement. The result of oil content analysis obtained an average value of 0,00016 ppm. The highest oil content at station 3 is 0,00035 ppm and the lowest at station 2 is 0,00011 ppm. The results of the calculation of the abundance of planktonic diatoms ranged from 5.014 to 22.062 cells/L. The highest abundance at station 1 was 17.716 cells/L. The lowest abundance was at station 2 which was 9.694 cells/L. Simple linear regression test result, obtained equation Y= 14,2644+(-3802,27x). The coefficient of determination (R2)= 0,002 states 0,2 % of the abundance of planktonic diatoms is influenced by oil content and the rest is influenced by other environmental factors. Correlation coefficient (r) = 0,053, so the relationship of total oil content with the abundance of planktonic diatoms is very weak.

Abstract

The entry of vaname shrimp into Indonesia was to replace tiger prawns (Penaeus monodon) which at that time experienced a decline in quality. Although vaname shrimp is famous for having various advantages, there are still obstacles encountered during the cultivation period, one of which is the attack of vibriosis caused by the bacterium Vibrio harveyi. This study aims to determine the effect of adding white turmeric extract (Curcuma zedoaria) on the immune system of white shrimp (Litopenaeus vannamei) which was challenged with Vibrio harveyi bacteria. This research was conducted for 60 days from March to May 2021 using experimental research methods. The research container used a container container (size 40x30x28 cm) and a stocking density of 20 fish/container with a volume of 20 L. The research design used was a completely randomized design consisting of 5 treatments with 3 replications where P1: artificial feed + Vibrio harveyi infection, P2: artificial feed + 0.1 mL NaCl injection, P3: artificial feed + 0,5% white turmeric extract + V.harveyi infection, P4: Artificial Feed + 1% white turmeric extract + V.harveyi infection, P5: Artificial feed + 2% white turmeric extract + V.harveyi infection. The results showed that administration of white turmeric extract (C.zedoaria) with a dose of 1% gave the best results and had a significant effect on the survival rate of 68.3%, Total Haemocyte Count of 21.63x10⁶ cells/mL, and Differential Haemocyte Count (hyaline cells). by 58.7%, semi-granulocytes by 18.33%, granulocytes by 23%) which play a role in the immune system of white vaname shrimp. In addition, the value of phagocytic activity was 68.8% and was able to suppress the growth of bacteria in the intestine at the lowest at 57.7×108 CFU/mL and suppress the number of vibrios to the lowest number at 26×106 CFU/mL.

Abstract

In the Koto Panjang Reservoir, the microplastic may originate from the degraded plastic waste as well as degraded plastic net from the fish culturing cages. The microplastic may be accidentally ingulfed as fish swallowing their food. To understand the presence of microplastic present in the stomach of wild common carps living around the fish net cage, a study was conducted in December 2020-February 2021. The fish were captured using fish net (3-5 inc mesh size), 3 times, once/ 2 weeks. The fish stomach was removed and the presence of the microplastic was identified. The stomach content of the fish was mixed with 10% KOH (minimum 3 x of stomach content volume) and was incubated for2 weeks to dilute the organic materials. Then the presence of microplastic was observed using a binocular microscope. Types and abundance of the microplastic was noted. Results shown that the types of microplastic present were films, fibers and fragments. The highest type of microplastic found in the stomach of the fish was films (2.3 particles/ fish), followed by fibers (0.6 particles/fish) and fragments (1.1 particles/ fish).

Abstract

The coastal waters of Semarang Bay have been polluted by heavy metal lead (Pb). The research was conducted from September 2015 to March 2016 with 3 stations at the Tambaklorok green mussel cultivation location. Analysis of the concentration of heavy metal Pb using the AAS (Atomic Absorption Spectrophotometer) method. Data processing using SPSS and Excel. The results showed that the average concentration of heavy metal Pb in the air ranged from 0.51 to 0.76 mg/L. The average concentration of heavy metal Pb in three observations obtained an average concentration of Pb between 4.975-20.43 mg/kg. Green mussels taken in the waters were sorted and separated according to the length of the shell and weighed 1 kg each according to the length of the shell. Small (2-3 cm), medium (3-4 cm) and large shells with long shells (5-6 cm). The results of the measurement of the concentration of heavy metal Pb in P. viridis showed that the average green mussel shell size 4-5 cm at the location of station III had the lowest concentration of heavy metal Pb at 0.24 mg/kg. Meanwhile, the highest average concentration of Pb in P. viridis was found at station I at 0.89 mg/kg with a shell length of 2-3 cm. The correlation equation between shell length and Pb concentration is Y= - 0.131 + 1.13 X. Standard error of the Estimate (SEE) is 0.19. While the standard deviation of 0.20 means that the predictor variable (water) to predict the dependent variable (shellfish) is feasible because SEE is greater than the standard deviation. The average value of the Bioconcentration Factor (BCF) of green mussels is smaller than that of medium-sized green mussels and large green mussels. Green mussels can be consumed by someone if the body weight is 60 kg, then as much as 5.8 kg in a week because it contains Pb.
