Abstract

A research has been conducated on using charcoal as a filter to control river water pollution with heavy metals from palm oil mill waste based on physical parameters in Kuantan Singingi district using SSA method. The process begin with taking sample from palm iol mill waste output, the the temperature and electrical conductivity of it is mesured. Heavy metal concentration (Zn) is mesured with Atomic Absorption (SSA). The highest electrical conductivity value before filtrasion was found in factory A sampel. The value is 8,87 x  10-4 Ωm-1with 0,241 mg/l Zn concetration. Electrical conductivity value decreased after filtration to 7,11 x 10-4 Ωm-1 with  0,216 mg/l mg/l Zn concetration. While the lowest electrical conductivity value before filtration was found in factory C sample. The value is 4,65 x 10-4 Ωm-1with 0,169 mg/l Zn consetration. Conductivity value decreased after filtration to 4,26 x 10-4 Ωm-1with 0,154 mg/l Zn contretation. These result explain that using charcoal as a filter for pollution control is uqite effective.

Abstract

This study aims to determine how much the pollution level of wells digging to the distance of wells from the coast by analyzing the values of the conductivity, salinity, pH and heavy metals such as Lead(Pb), Iron(Fe) and Manganese(Mn). The method used was purposive sampling with number of sample are 10 sample points with variation distance ± 100 m. Conductivity measurements were carried out in two ways, namely using a conductivitimeter and Wheatstone bridge. The measurement results using conductivity meter indicate that the average conductivity value of a well water sample is 125.50 - 80.04 μS/cm while the comparison using the Wheatstone bridge method has an error percentage value of 6.12 %. The salinity has values ranged from 0.112 - 0.093 ‰ which is classified as fresh water. The measurement of pH values shows indications of pollution, due to water classified as acid with a pH value ranging from 3.1 - 4.1. The measurement of the value of Iron(Fe) and Manganese(Mn) does not indicate water pollution due to heavy metals with an average concentration of Iron(Fe) 0.3697 mg/l and Manganese(Mn) 0.0391 mg/l. Comparison of the salinity and conductivity values to the well distance from the coast does not show relation that correlates with seawater intrusion in Mekar Indah Vilage.

Abstract

People who care about the environment always reject the use of peat land for large-scale plantation areas, because this can cause an increase in carbon gas and can even cause damage to peat land in Rimbo Panjang Village, Tambang District, Kampar Regency. that there was an event of a land fire which almost hit the residential area in Rimbo Panjang village, Kec. Kampar District Mine on February 24, 2015. That there are complaints from the community in Rimbo Panjang village, Kec. Kampar Regency Mine about environmental conditions or smog. The implementation of Eco-Technology can protect the environment of peatlands to maintain sustainability and avoid fire from peatlands and regulate groundwater management on peatlands.

Abstract

The analysis of aquifer potential has been done in the Rumbai Pesisir District of Pekanbaru City by using the Schlumberger configuration geoelectric method. Data was taken from four villages in Rumbai Pesisir Subdistrict, in Lembah Damai, Limbungan, Limbungan Baru and Meranti Pandak. The result obtained using progress software showed that each location has aquifer with different layer and thickness. The highest aquifer resistivity is located in Lembah Damai Village with a resistivity value of 549.50 Ωm in the third layer, while aquifer with the lowest resistivity value is located in Meranti Pandak Village with a resistivity value of 15.69 Ωm in the third layer. The highest thickness aquifer located in Meranti Pandak Village with a thickness of 48.47 m in the third layer, while the lowest thickness aquifer located in Limbungan Baru Village with a thickness of 11.51 m in the second layer. The Result from lithology of each path shows that flow pattern of water flowing from Lembah Damai Village to Limbungan Village, then Meranti Pandak Village and then Limbungan Baru Village. The results of the analysis of aquifers potential indicate that underground water reserves in the Rumbai Pesisir District of Pekanbaru City are 17.13 x 109 m³.

Abstract

Forest fires in Riau Province are the biggest contributor to air pollution that spreads to the urben area of Pekanbaru. PM10 is one of the most dangerous elements contained in forest fire smoke. This study aims to map areas that have accumulated the spread of PM10 in the city of Pekanbaru. This research has been carried out using a data interpretation methodology using data on the value of PM10, rainfall, air temperature, humidity, wind direction and wind speed in the form of monthly data from 2015 – 2019. Data processing is carried out using Microsoft office excel 2017, SPSS, surfer 17, google earth pro. The result of the analysis there is a significant effect of wearther parameters on PM10. Wind speed has a strong influence on the spread of PM10. Mapping of wind distribution patterns and distribution patters of PM10 in sub-district Limapuluh every year and the wind direction accoriding to the wrplot flower chart always goes to sub-direction Limapuluh.

Abstract

This study aims to determine the magnetic properties and particle size of the volcanic ash of Sinabung Mount with experiment method. Magnetic properties studied were magnetic degree, magnetic induction magnetic susceptibility, and mass susceptibility of sample. The samples used were volcanic ash taken from the west part of Sinabung, precisely at Gurukinayan village. The ash samples were taken horizontally on the slopes of the Mountain with the amount of 1.5 Kg each point with the number of 10 points (A to J). Separation of concentrate of ash was done using a Neodymium Iron Boron (NdFeB). The magnetic induction of ash and concentrate was measured using a Pasco 2162 Probe using a solenoid is 3 cm in diameter, 10 cm in length and 2000 coil turns. Magnetic induction without a core was measured as a current function (2,4,6,8,10)A and a distance of 1 to 5 mm. The total magnetic induction of ash and concentrate was measured as a current function and the particle sizes was measured using a Light Microscope. The results showed that the greate magnetic degree value at point B of 7.02% and the lowerst level of magnetism is at point J was 1.07%. The largest particle sizes is at point B and the smallest is at point J with particle size of 0.175-0.90 mm. The highest average magnetic susceptibility value for concentrate at point B is 87.32 x 10-3 and the lowest at point F is 20 x 10-3. Based on the mass susceptibility value of the concentrate obtained the volcanic ash of Mount Sinabung is at interval (46–80.000) x 10-8 m3/kg of mass susceptibility value at each location point which contains Ilmenite particles (FeTiO3).
