Abstract

This research was held on June to August 2012 and aims to analyze the content of heavy metals Cd and Pb in sediment, sea water and tembakul (Periophthalmus sp) in Dumai waters and to determine the correlation between the three. The method used was a survey method with 4 stations sampling were set by purposive with the inclusionof the sourceof pollutants. There was a difference between the content of Cd and Pb in sea water, sediment and tembakul (Periophthalmus sp), in which the heavy metal contentin the sea wateris lower than in sediment and fish. The highest content of Cd in sea water is in Stations1, 2 and 3, which .077mg/L. In the sediment, the highest contentis in Station 3, which is1.819μg/g and the lowest at Station 4, which is 0.690μg/g. Another case in Tembakul, the highest content of Cd is in Station 1, which is 0.447μg/g. Pb content of sea water is highest at Station 2, which is 0.787mg/L and the lowest is on station 4, is equal to 0.370mg/L. The highest content of Pb in the sediment is at station 2, which is 33.221μg/g and remained the lowest at Station 4 with Pb contents value of 19.018μg/g. At tembakul (Periophthalmus sp), the highest Pb content is in Station 2, which is 4.976μg/g and the lowest at Station 4, which is 2,555μg/g. The content of Cd and Pb tembakul in Dumai waters under the in fluence of Cd and Pb content of water and sediment 54,2% increase in the content of Cd in sediments under the in fluence of the water content of Cd.62.5% Cd metal content in fish is in fluenced by the water content of Cd and 42.6% are in fluenced by the Cd conten to f the sediment. For Pb in sediments 60.4% in fluenced by the Pb content of the water. 68.1% Pb metal content in tembakul in fluenced by the water content of Pb and 65.9% under the influence of the Pb content of sediment. It means, if the content of heavy metals in water and sediment increases, it will give a negative impact to tembakul.Keyword: Heavy Metal, Dumai, Water, Sedimen, Tembakul

Abstract

This research aims to analyze 1) condition of rocks mining operations existing, 2) stakeholders understanding of good mining practice and 3) physical environment impact of rocks mining operations in sub district of Pangkalan Kerinci Regency of Pelalawan. The methods used to collect the data is a survey method with qualitative descriptive approach. The Mining operations existing condition of the eight mines do not have permit except locations III that only have mining permit (IUP). Mining system still uses an open system and not fully implement the K3 system, environmental protection and post-mining land cover. Stakeholders understanding about good mining practice include: aspects of licensing (72% = understand), technical mining (65% = understand), environmental protection (73% = understand), relationship of the upstream-downstream / conservation / value-added of community development / the area around the operation sites (66% = understand), frame rules regulations and applicable standards appropriate stages of mining operations (79% = very understand ). Health safety (44% = less understand), prepare a post-mining land ( 45% = less understand). Physical environmental impacts arising from mining, include: the loss of natural beauty, the loss of some habitat for flora and fauna, the increase in water runoff (surface run-off), noise (noise) and vibration (ground vibration) due to the operation of heavy equipment, air pollution, oil and used oil spills, soil subsidence and the presence of dry holes without plants.Keywords : Mining, Environmental Degradation, Pelalawan

Abstract

Network for special road, especially in urban imbalance occurs between the growth rate of the road on one side with a growth rate of vehicles on the other, where the growth path is much smaller than the growth rate of the vehicle, this means showing the occurrence of an excessive load on the road. These conditions resulted in traffic congestion, disrupted travel convenience, travel fatigue, boredom trips, increased air pollution, wastage of time and material it also occurs on roads Soebrantas.The observation of the volume of vehicles on Sunday has the highest volume of 87.059 units 86.384 units followed Saturday and Sunday 73.125 units. The observation of Sunday vehicle top speed is 56,90 km/h followed Friday 54,57 km/h and Saturdays 50,26 km/h. Contributions load of pollutants CO are the largest contributor of pollutant loads. The total load of pollutants on Friday 5.265.420,06 grams/day consisting of CO: 92,43%, NOx: 6,32%, PM10: 1,0% and SO2: 0,25%. Total pollutant load Saturday 4.285.967,57 grams/day percentages: CO: 91,59%, NOx: 6,99%, PM10: 1,13% and SO2: 0,29%. The pollution load on the Sunday 5.215.978,35 grams/day percentages: CO: 92,29%, NOx: 6,41%, PM10: 1,04% and SO2: 0,26%.The main contribution of CO and NO2 pollutant load is predominantly gasoline fueled cars, the dominant source of PM10 motorcycle and SO2 pollutant load is the dominant truck. The results of ambient air quality monitoring for parameters of CO, NOx, PM10 and SO2 in Soebrantas streets on Friday to Sunday is still below the threshold value of ambient air quality.Keywords: Transportation, Motor Vehicles, Pollutant Load
