This study was undertaken to determine the level of 16 polycyclic aromatic hydrocarbon (PAH), listed as priority pollutants by the United States Environmental Protection Agency (USEPA), in surface soils around a coal-transporting facility in the western part of South Kalimantan, Indonesia. Three composite soil samples were collected from a coal stockpile, coal-hauling road, and coal port. Identification and quantification of PAH was performed by gas chromatography-mass spectrometry. The total content of 16 USEPA-PAH ranged from 11.79 to 55.30 mg/kg with arithmetic mean value of 33.14 mg/kg and median of 32.33 mg/kg. The 16 USEPA-PAH measured levels were found to be greater compared with most of the literature values. The levels of high molecular-weight PAH (5- and 6-ring) were dominant and formed 67.77-80.69 % of the total 16 USEPA-PAH The most abundant of individual PAH are indeno[1,2,3-cd] pyrene and benzo[a]pyrene with concentration ranges of 2.11-20.56 and 1.59-17.84 mg/kg, respectively. The degree of PAH contamination and subsequent toxicity assessment suggest that the soils of the study area are highly contaminated and pose a potential health risk to humans.

Concentrations, spatial distribution, and sources of 16 polycyclic aromatic hydrocarbons (PAHs), listed as priority pollutants by the United States Environmental Protection Agency (USEPA), were investigated in surface soils of three different coal stockpile, agricultural, and residential sites in South Kalimantan Province, Indonesia. Total PAHs concentration ranged from 4.69 to 22.67 mg kg(-1)-dw. PAHs concentrations in soil of coal stockpile sites were higher than those in agricultural and residential soil. A complex of petrogenic origin and pyrolytic sources was found within the study area, as suggested by the isomeric ratios of PAHs. The results of principal component analysis and multiple linear regressions (PCA/MLR) showed that three sources contributed to the PAHs in the study area, including biomass and coal combustion (48.46%), raw coal (35.49%), and vehicular emission (16.05%). The high value of total benzo[a]pyrene equivalent concentration (B[a]Peq) suggests that local residents are exposed to a high carcinogenic potential.

Determining category of physical appropriateness of DWS under health office development and controlling program of Hulu Sungai Utara Regency, Determining Microbiology quality of  DWA under health office development and controlling program of Hulu Sungai Utara Regency, analyzing the correlation of physical appropriateness and microbiology quality if DWS under health office development and controlling program of Hulu Sungai Utara Regency. This is a quantitative study using cross-sectional research design in which the research was conducted in a certain period of time, the location of research was in 10 service area of the public health center in 9 subdistricts under health office development and controlling program of Hulu Sungai Utara Regency. It was found that 30 DWS (Drinking Water Storehouse) is under health office development and controlling program of Hulu Sungai Utara Regency, DWS which categorized as physically not Appropriate (TLF) was 20 DWS (66,7%) and categorized as physically appropriate (LF) was 10 DWS (33,3%). Microbiology quality of Balangan, Tabalong, Negara, Tangkawang and Rantau Bujur Darat River were excess the standard of quality of class I intended for the drinking water source. Microbiology quality of water source (PDAM) from 30 samples, it was found that 14 samples (46,7%) contained Coliform and E. coli, there were 2 samples (6,7%) contained only Coliform. Quality of microbiology and water product of  30 DWS, it was found that 2 DWS contained Coliform, all water of DWS production did not contain  E.coli. Statistical test of the correlation of physical appropriateness and microbiology quality of river water cannot be conducted because all samples have the same category which is TMS so that there was no difference in result data of category determination. There was no significant difference between physical appropriateness with microbiology quality of Coliform (p=0,260) and E.coli (p = 0,235) raw water of DWS. There was no significant correlation of physical appropriateness with microbiology quality of Coliform (p = 0,540) water product of DWS, meanwhile for statistical test for correlation of physical appropriateness and microbiology quality of E.coli of water product cannot be conducted because there was no difference in result data of category determination so that all samples has the same category.

ABSTRAK Penelitian ini bertujuan untuk memetakan sebaran tempat pembuangan sampah (TPS) ilegal dan menganalisis faktor-faktor yang mempengaruhinya. Penelitian ini dilakukan di Kota Banjarbaru, Kalimantan Selatan. Data penelitian diperoleh melalui  pengamatan dan pengukuran secara langsung di lapangan serta studi pustaka. Seluruh data yang diperoleh, baik yang berbasis geografis maupun yang bersifat deskriptif dan numerik diolah dan dipetakan dengan menggunakan perangkat lunak ESRI ArcView GIS 3.3. Hasil penelitian menunjukkan bahwa di Kota Banjarbaru terdapat 64 lokasi TPS ilegal dan sebarannya dipengaruhi oleh jarak dari sungai, jarak dari jalan utama, jarak dari jalan lokal, tutupan lahan, kepadatan penduduk, tingkat pendidikan, jenis pekerjaan, cara membuang sampah, cakupan wilayah layanan pengangkutan sampah dan jarak dari TPS resmi.Kata kunci: Kalimantan Selatan, pembuangan sampah ilegal, pemetaan, sampah domestik, sistem informasi geografis
