Analysis of Heavy Metals Concentration in Textile Wastewater in Batik Industry Center

The textile industry is the main source of environmental pollution in terms of quality and quantity. It consumes large amounts of water (200 m3/ tonne of products), and around 90% of the quantity is wastewater. Improper disposal of textile wastewater will cause serious environmental problems due to the presence of heavy metals in the waste which will adversely affect aquatic organisms. To analyze, the concentration of heavy metals in textile (batik) wastewater was collected from 15 small, medium, and large-scale textile industry waste disposal centers located at the Batik Industry Center of Kampoeng Batik Laweyan Surakarta, Indonesia August 2019. Standard methods of 22nd Edition 2012 APHA -AWWA-WEF with inductively coupled plasma optical emission spectroscopy (ICP-OES) was used to analyze the concentration of Iron (Fe), Copper (Cu), Chromium (Cr), Cadmium (Cd), Lead (Pb) and Nickel (Ni) in the sample. The results of the analysis showed that from 15 sample locations, several locations had levels of Cu, Pb, Ni, Cr, and Cd below the detection limit, i.e.  2 (<0.01 ppm), 13 (<0.02 ppm), 13 (<0.01 ppm), 15 (<0.01 ppm), and 15 (<0.02 ppm) locations for each metal respectively, while Fe levels were above the detection limit at all locations. The mean levels and number of locations for Fe, Cu, Pb, and Ni were 2.63 ± 5.01 (n = 15), 0.48 ± 0.99 (n = 13), 0.05 ± 0.03 (n = 2) and 0.02 ± 0.00 (n = 2) and the ranges of each metal level were 0.07-19.4 ppm, 0.01-3.73 ppm, 0.02-0.07 ppm, and 0.01-0.02 ppm respectively. Among these heavy metals, the highest concentration was Fe, and all samples had Cr and Pb levels below the detection limit. By comparing the results of this study with the safe limit for industrial wastewater according to Central Java Provincial Regulation No. 5 of 2012, only wastewater originating from two sampling locations can be used for irrigation and aquaculture, namely at locations B2 and B

Stromal Derived Factor-1, C-X-C Motif Receptor-4 and Vascular Endothelial Growth Factor Expression after Induction of Garcinia mangostana. L Peel Extract in Bone Marrow Mesenchymal Stem Cells Culture

survival was unavoidable when stem cell being transplanted. Garcinia mangostana. L Peel may possess beneficial active compound to enhance homing factor of stem cells. C-X-C Motif Receptor-4 (CXCR4), Stromal Derived Factor-1 (SDF-1) and Vascular Endothelial Growth Factor (VEGF) play an important role in stimulating endogenous Bone Marrow Mesenchymal Stem Cells (BMMSCs) mobilization. The aim of this research to find out whether mangosteen (G. mangostana. L) peel extract can induce the expression of a CXCR4, SDF-1 and VEGF in BMMSCs culture. BMMSCs were taken and isolated from femur of male Wistar rats (Rattus novergicus). BMMSCs were cultured then added with mangosteen (Garcinia mangostana. L) peel extract. In this study, the culture of MSCs divided into 2 groups, group 1: added G. mangostana. L peel extract and group 2: without G. mangostana. L peel extract. The examination of SDF-1and CXCR4 expression by using enzyme linked immunosorbent assay (ELISA), meanwhile the VEGF expression by using Immunocytochemistry. Statistical analysis was test using Levene test for variance homogeneity and normality test with the Saphiro-Wilk test. If the data is normally distributed then a different test is performed using the t-test (p<0.05). There was a significant difference in the expression of SDF1-CXCR4, and VEGF (p<0.05) in BMMSCs cells culture between two groups (p<0.05). Conclusion: G. mangostana peel extract is able to induce the expression of a number of proteins, growth factors and chemokines, such as VEGF, CXCR4, and SDF-1
