Abstract

Plastic waste can be found everywhere, including in the Koto Panjang Dam. As the plastic waste degraded, the microplastic materials may be distributed in the water and it may be accidentally swallowed by omnivorous fishes such as  Puntius schawanafeldii.  To understand the presence of the microplastic materials in the fish stomach, a research has been conducted in December 2020 - February 2021. The number of P.  schawanafeldii captured was 30 using fish net in 3-5 inch mesh size. The fish was dissected and the stomach was removed. Then the stomach content was added with 10% KOH andwas incubated for 2 weeks to delute the organic materials. Then was investigated under a binocular microscope to find out the microplastic materials. Results shown the type of microplastic present in the stomach of P. schawanafeldiiwas namely film, fibre, and fragment. The most common type of microplastic found was film, followed by fragments and fibre. The abundance of microplastic in the stomach of P.  schwanafeldii was around 2 – 15,8 particles/fish

Abstract

In the Koto Panjang Reservoir the microplastic may originated 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 present of microplastic present in the stomach of wild common carps living around the fish net cage, a study was conducted on 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

Mangrove plant, Sonneratia alba, can be found abundantly in Indonesia. Some previous studies reported phytochemical screening and bioactivity test of Sonneratia sp. as anti-diabetic (in vitro and in vivo analysis). However, phytochemical identification of S. alba leaves and inhibitory activity of α-glucosidase as anti-diabetic have not been reported. The purpose of this study are to identify phytochemical compounds of methanolic extracts S. alba leaves, and to predict inhibitory mechanisms of S. alba leaves against α-glucosidase through in silico analysis. In this study, the research method consists of two steps namely identification phytochemical compounds of methanolic extracts S. alba leaves, and prediction inhibitory activities of phytochemical compounds of methanolic extracts S. alba leaves against α-glucosidase by molecular docking (in silico) analysis. Methanolic extracts S. alba leaves contained orientin, vitexin, luteolin, oleanolic acid and reserpine. Reserpine was identified for the first time in S. alba leaves. Based on in silico analysis, binding energy of orientin, vitexin, luteolin, oleanolic acid, reserpine and acarbose (positive control) against α-glucosidase were -9,7; -9,7; -9,2; -8,6; -10,0 dan -8,3 kcal/mol. This result indicated that compounds inhibited α-glucosidase activities and can be considered as antidiabetic agent.

Abstract

Gouramy (Osphronemus gouramy) is a freshwater fishery commodity with a large enough demand and a fairly expensive price compared to other freshwater fish. The purpose of this study was to determine the effect of temperature on larval quality and growth of gouramy fry. The research method used is an experimental method using a Completely Randomized Design (CRD) consisting of two treatments of water media temperature, namely 1) Treatment A = The temperature of the media follows room temperature (control treatment), and 2) Treatment B = The temperature of the medium was set constant at a temperature of 30ᵒC. Each treatment was repeated six times to obtain 12 experimental units. Research parameter data were analyzed statistically using variance (ANOVA) at a 95% confidence level using the t-test. The results showed that the degree of hatching of gouramy eggs, larval size, absolute growth, relative growth, daily specific growth rate and survival rate of gouramy larvae at room temperature and 30°C were 90.38% and 98, respectively. 76%; 0.54 cm and 0.66 cm; 0.86 cm and 0.87 cm; 157.52% and 133.26%; 3.99% and 3.58%; and 74.78% and 91.22%. The study concluded that eggs incubated at room temperature (25-28°C) and 30°C gave significantly different effects on hatching rates and post-hatching larvae size. Larval rearing at room temperature and 30°C gave no significant effect on absolute growth but significantly different on relative growth, daily specific growth rate and survival rate

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

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

Anadara granosa is one of the bivalves that are often found in public markets. This study aimed to study the relationship between length-weight and sex ratio of blood clams (A. granosa) in the coastal waters of West Rangsang. Sampling was carried out every month at three stations. Shells were collected from a 1 x 1 m2 plot on a quadratic transect. The relationship between length and weight was analyzed by regression analysis. The sex ratio between the number of female and male blood clams in each month of sampling was calculated and followed by the Chi square test to test the similarity. The results showed that the relationship between length and weight of A. granosa was positive allometric. The sex ratio of female and male blood clams in the waters of West Rangsang is not balanced. The number of male blood clams is more than the female.
