This study describes the chemical speciation of Pb, Zn, Cu, Cr, As, and Sn in soil of former tin mining catchment. Total five sites were selected for sampling and subsequent subsamples were collected from each site in order to create a composite sample for analysis. Samples were analysed by the sequential extraction procedure using optical emission spectrometry (ICP OES). Small amounts of Cu, Cr, and As retrieved from the exchangeable phase, the ready available for biogeochemical cycles in the ecosystem. Low quantities of Cu and As could be taken up by plants in these kind of acidic soils. Zn not detected in the bioavailable forms while Pb is only present in negligible amounts in very few samples. The absence of mobile forms of Pb eliminates the toxic risk both in the trophic chain and its migration downwards the soil profile. The results also indicate that most of the metals have high abundance in residual fraction indicating lithogenic origin and low bioavailability of the metals in the studied soil. The average potential mobility for the metals giving the following order: Sn > Cu > Zn > Pb > Cr > As.

Ahmad Soleh, Wagini, Vero Agustin; Market Levy is a charge withdrawn by the Department of Industry and Trade to compulsory retribution for the use of facilities in the form of stalls, kiosks and courtyards provided by the city government of Bengkulu. This study aims to examine the potential of public market retribution in Bengkulu City. Data collection techniques in this study using documentation. Secondary data was obtained from the Office of Industry and Trade of Bengkulu City. The market retribution potential formula is used in this method of study. The results showed that the existing market potential in Bengkulu City fluctuated. The average potential of general market retribution is Rp 2,220,464,960 per year with an average growth of 2.51% per year. This is in line with the realization of public market levies that also experience fluctuations. The average realization of general market retribution revenue amounted to Rp 1,854,906,535, - with an average growth of 6.53% per year. The percentage of realization achievement of potential revenue of general market retribution in Bengkulu city from 2014 to 2016 were 82.08%, 80.23% and 88.07% respectively with an average of 83.53% per year. Achievement average achievement above 80% is considered good. However, the local government of Bengkulu city should always try to increase the realization of acceptance of public market retribution with its potential.Key Words: Potential, Public Market Levy, Bengkulu City.
