Abstract

Teknopark Pelalawan area is an area designed as a center for the development of local advantages generated through research. In the region there will be College of Technology Palalawan and various Research and Development Center as to the development of local products, industrial downstream palm oil products, forest products and small and medium scale industries. Means and supporting facilities such as clean water, waste water and drainage systems are currently being incorporated into the master document teknopark region Palalawan plants. Infiltration measurements conducted to support the planning of drainage systems in order to manage rainwater in the area of teknopark Palalawan. This measurement is done in both land area units, namely: dry land units and land units of wet peat. Infiltration measurements done using an instrument called a double ring infiltrometer. To measure the rate of infiltration were analyzed using Kostiokov method. The result is: infiltration in the drylands of 1.5 mm / min on a peaty wetland was 0.4 mm / min. The conclusion that can be drawn is that in order to manage the rainwater would be more efficiently carried out on dry land unit. Keywords: teknopark Pelalawan, infiltration rate, kostiakov, double ring infiltrometer, constant infiltration rate

Abstract

Organochlorine pesticides (OCPs) in waters from five sampling point in Jabodetabek area have been determined using HRGC-HRMS. A total of 21 OCPs have been analyzed, however only few of OCPs were detected. Among HCH isomers, only -HCH and lindane (-HCH) were detected with concentration in the range of ND-0,25 ng/L and 0,083 – 0,82 ng/L, respectively. Interesting result was found, where HCB was detected in relatively high in water of Ciliwung river, Pluit Jakarta with concentration of 688,28 ng/L. HCB is a compound which is not only intentionally produced as pesticide, but also unintentionally produced from industrial by-product. Therefore, contamination of the river water may come from industrial processes which are located near sampling point. If compared with river water quality criteria of PP No.82 Tahun 2001, it results were below the standard of river water quality Class I. Keywords : organochlorine pesticides (OCPs), waters, Indonesia, industrial by-products.
KONSENTRASI POLYCHLORINATED BIPHENYLS (PCBS) DAN POLYCHLORINATED DIBENZO-P-DIOXINS/POLYCHLORINATED DIBENZOFURANS (PCDDS/FS) DALAM AIR DARI DAERAH PERKOTAAN JABODETABEK Shoiful, Ahmad; Nugroho, Rudi; Fujita, Hiroyuki; Honda, Katsuhisa

Abstract

Determination of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) in water samples from Jabodetabek urban area was conducted. In the results, a unique pattern were found interestingly in Ciliwung river, Pluit, Jakarta, where decachlorinated biphenyl (PCB IUPAC #209), and dichlorinated biphenyl (PCB IUPAC #11) were detected at relatively high concentrations as 406.77 ng/L and 6.38 ng/L, respectively. This congener pattern is different with commercial PCB mixtures, such as arochlor, kanechlor, or chlophen. Octachlorinated dibenzo-p-furan (OCDF) was also detected at a significant concentration in this water as 3.10 ng/L. Decachlorinated biphenyl (PCB IUPAC #209) and OCDF were associated with industrial by-products. Meanwhile, dichlorinated biphenyl (PCB IUPAC #11) was associated with colour pigment which widely used in consumer goods, such as paint and printed ink. Thus, PCBs and PCDD/Fs contamination might have arisen from industrial by-products where various industries located near sampling point. Keywords: polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins /polychlorinated dibenzo-p-furans (PCDDs/Fs), waters, Jabodetabek, industrial by-products.
