Abstract

Peripheral blood sel mononuclear cell (PBMC) is a white blood cell that can be isolated using the gradient centrifugation method. Ficoll is a reactant which can be used in this method because it produce a high viability i.e. 97.1% 1.0%. This research aims to isolate PBMC from healthy human blood. PBMCs result is used for analysis of dengue virus immune response.Dengue viruses infect PBMC, so going on the secretion of cytokine which is one marker of severity of dengue disease. Expression of cytokines can be measured using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR).Venous blood from healthy human is takenaseptically using anticoagulants heparin, then PBMC is isolated with ficoll gradient centrifugation method to produce buffy coat that contain PBMC. Viability of PBMC is calculated using hemositometer with the help of a microscope.Based on the results obtained by PBMC isolation per mL of venous blood that is 2, 08x106 up to 2, 61x106 with an average of 2, i.e. 31x106 withviabilityof 95-99%. These results indicate that this method is quite effective in isolating PBMC from healthy human blood.Keyword : blood, ficoll, centrifugasigradien, PBMCs

Abstract

Date seeds are waste from palm fruit processing that has not been utilized optimally. Date seeds contain flavonoids which are known to act as antioxidants. The aim of this study was to determine the antioxidant activity and flavonoid of methanol extract which was carried out by soxhletation and its fractionation results. Date seeds are made into simplicia, soxhlet extraction with methanol, then the methanol extract is fractionated in stages by liquid-liquid partition with n-hexane, ethyl acetate, and n-butanol. Each fraction and extract was determined by its antioxidant activity with the DPPH method and its flavonoid was determined by spectrophotometry. Ethyl acetate fraction has the strongest antioxidant activity with the lowest IC50 value, that is equal to 5.74 ± 0.05μg/mL, followed by methanol extract of 9.55±0.53 μg/mL, n-butanol fraction 19.73±0,58 μg/mL, and n-hexane fraction of 289.59±10.52 μg/mL, while the IC50 value for vitamin C as a positive control was 4.29±0.74 μg/mL. The highest flavonoids were produced from ethyl acetate fractions which amounted to 1484.33 ± 161.47 mg Quercetin Equivalent (QE) / 100 g, followed respectively by methanol extract of 282.84±13.72 mg QE/100 g.

Abstract

Wastewater from the batik industry in Bogor City is the most waste produced from the dyeing process. The batik industry produces waste with concentrated color due to the high concentration of color content from the dyeing process. This affects water bodies as a direct disposal site for waste. Batik waste also has the potential to contain heavy metal compounds derived from the composition of dyes. This will have an impact on the disruption of the balance in the environment around the industry. Therefore, it is necessary to characterize batik wastewater to determine the pollutant content. This research aims to characterize the batik industry wastewater in the city of Bogor by measuring the levels of COD, BOD, TSS, pH, temperature, total chromium content, total phenol content, and sulfide content according to the parameters P.16/MENLKH/SETJEN /KUM.1/4/2019. The results showed the characteristics of the wastewater from the batik industry in Bogor City with levels of COD in dyeing waste at 797 mg/L and total waste at 52463 mg/L, BOD levels in dyeing waste at 431 mg/L, and total waste at 238 mg/L. TSS in the dyeing waste is 706.5 mg/L and the total waste is 3679 mg/L, the temperature in the dyeing waste is 26.9 °C and the total waste is 26.3°C, pH in staining waste at 1.62 and total waste at 6.82; the total chromium content in the staining waste was 2.62 mg/L and the total waste was 940.2 mg/L, the total phenol content and sulfide content in the dyeing waste and total waste was not detected. The characteristics of batik waste are not by the established quality standards, so there is a need for processing before the waste is discharged into the environment.

Abstract

Green grass jelly (Premna oblongifolia Merr) is a plant that belongs to the Verbenaceae family with the Premna genus. The genus Premna has about 200 species in the Verbenaceae family which are spread in tropical to subtropical areas such as Asia, Africa, and Australia. This plant has potential as antibacterial, antipyretic, anti-inflammatory, and antioxidant. This research was conducted to make an extract of endophytic bacteria obtained from green grass jelly plants by maceration method. The extract obtained was tested for its antibacterial activity by disc diffusion method. Extracts with the highest antibacterial activity were identified by FTIR and GCMS. The results showed that the methanol extract of endophytic bacteria of green grass jelly plants had broad spectrum antibacterial activity because it was able to inhibit the growth of Gram-positive bacteria (Bacillus subtilis) and Gram-negative bacteria (Pseudomonas aeruginosa). The results of FTIR and GCMS showed that the active compounds contained in the endophytic bacteria of green grass jelly plants were thought to be Nerolidol compounds or 3,7,11-trimethyl-1,6,10-dokatrien-3-ol which are secondary metabolites of the sesquiterpene alcohol group and play a role in as an antibacterial.

Abstract

Dates (Phoenix dactylifera) is one of the plants that very useful, but the date palm seeds that become waste have not been widely used. Based on studies that are known to contain bioactive compounds that can be suspected as antioxidants, antimicrobials and anti-inflammatory. However, research on immunostimulants from dates, especially in silico and in vitro, has not been widely carried out. Therefore, this study aims to determine the potential of date seed bioactive compounds as immunostimulants through in silico against Human Glycosylation-Inhibiting Factor (1GIF) and Human Cyclooxygenase-2 (5IKR) receptors as well as in vitro through the proliferation of lymphocyte cells of male mice (Mus musculus) balb/c strains with the MTT Assay methods. The results of the in silico study showed that 5-O-Caffeoylshikimic Acid had the highest interaction and stability, Gibbs free energy with 1GIF and 5IKR receptors, -6.68 kcal/mol and -8.58 kcal/mol, respectively. This value is known to be higher than the Caffeic Acid as control ligand. The results of in vitro research obtained methanol extract of date seeds at a concentration series of 6.25; 12.5; 25 µg/mL had higher lymphocyte cell proliferation activity which was indicated by an increasing OD value, and at a concentration of 25 μg/mL produces the highest immunostimulant activity. Therefore, date seed extract containing the compound 5-O-Caffeoylshikimic Acid can potentially be an immunostimulant agent.
