    ANALISIS KANDUNGAN LOGAM BERAT Cd, Pb, DAN Mn PADA SEDIMEN KOLAM TPA MUARA FAJAR PEKANBARU
    (2014-03-27) Panjaitan, H.; Bali, S.; Hanifah, T. A.
    The concentration of three heavy metals (Cd, Pb, and Mn) had been known in TPA ponds sediment Muara Fajar Pekanbaru. Pond sediment samples were taken of four TPA ponds in pre-monsoon season (June 7, 2013) and brought to laboratorium for analyzing. Determination of the concentration of heavy metal Pb and Cd was done using Atomic Absorption Spectrophotometry, and determination of the concentration of heavy metals Mn was performed by Persulfat Kolorimetri. Results of heavy metal analysis in the TPA ponds sediment are as follows: Cd: 0-0,0003 mg/g; Pb: 0,0104-0,0150 mg/g; and Mn: 0,3077-0,8928 mg/g. To assess metal contamination in the TPA ponds sediment, USEPA (United Stated Enviromental Protection Agency) guidelines were applied. Based on the guidelines, TPA ponds sediment was unpolluted of heavy metal Cd and Pb. Metal that potential as pollutant is Mn in every TPA ponds. In general all TPA ponds sediment have been polluted and need to be investigated further

    The FinalWaste DisposalMuara Fajar is the final waste disposal in Pekanbaru. The waste is potential as a pollutan to our environment.Leachate contains organic and inorganic materials such as heavy metal which precipitate at the bottom of the ponds. The purpose of this study were to determine thecontent of nitrogen, phosphor, and potassiumin the sediment of all ponds.Sample were taken from eight sampling point in eachponds. Total nitrogen content was analyzed using titration method, phosphor content was determined using UV-VIS spectrophotometer (Spectronic Milton Roy) and pottasium content was determined by Flame Photometer (Jenway Series PFP 007). We found a various concentration of nitrogen, phosphor, and potassium from all ponds. The highest concentration of total nitrogen (0,5868%) and phosphor (0,1238%) was found in the sediment third pond, while the highest potassium content was found in sediment from pond (0,0884%).

    ANALISIS SENG(Zn), KROM (Cr) DAN KOBAL (Co) PADA SEDIMEN KOLAM INSTALASI PENGOLAHAN AIR LIMBAH (IPAL) TPA MUARA FAJAR PEKANBARU

    The advantages of sediment that formed by leachate water precipitation n waste reservoir ponds could be determined through analysis of metal content which ere obtained from decomposition process of garbage piles. The sediment samples were, collected from TPA Muara Fajar Rumbai-Pekanbaru, from four ponds and eight sampling points were then choosen from each pond. All samples were destructed by adding nitric acid (HNO3 1:1) and chloride acid (HCl 1:1), to analyze the content of heavy metals, and then measured by using UV-Vis spectrophotometer for Cr content, atomic absorption spectrophotometer was used for Co and Zn content. Our results showed that four samples contained Cr and Zn with different concentrations while Co was not detected. Zn content of sediment samples were ranged between 0.5899 to 0.6625 mg/g while Cr content was ranged between 0.1363 to 0.4029 mg/g. These results showed that the sediment could be used as a fertilizer for city ornament plants .

    BEBAN PENCEMARAN LOGAM BERAT Hg DAN SO42- DARILIMBAH TAMBANG EMAS TERHADAP BADAN AIR SUNGAI SINGINGI KUANSING
    (2014-03-27) Firnadi; Hanifah, T. A.; Bali, S.
    The illegal gold mining at the district of Kuantan Singingi resulted the presence of dangerous heavymetalsin liquid waste in the riverof Kuantan Singingi. The aim of this study was to determine the contamination level of mercury and sulfate in Kuantan Singingi river water. Concentration of Hg was determined by using SSA while the concentration of sulfate was calculated by using UV- VISspectrophotometry. The highestconcentrationof Hg(4.066 ppb) was found inthe thirdweek ofsampling timefromstation3, whilethe lowest (1.091 ppb) found inthe firstweek ofsampling timefrom station5. Hglevelsatstation3has passed the limit of Hg contentaccording to Government RuleNo82, 2001(1 ppb). The highest sulfate content was found (25.065 mg/L) in the third weeks ofsampling timefrom station 4 and the lowest (1.948 mg/L) was in the secondweekonstations8.Based onThe Goverment Rule No.82(2001), thelevel of sulfate inall stationswaslower then water quality standard (400ppm).

    POTENSI ABU CANGKANG KERANG DARAH (Anadara Granosa) SEBAGAI ADSORBEN ION TIMAH PUTIH
    (2014-03-27) Afranita, G.; Anita, S.; Hanifah, T. A.
    The waste of blood clam seashells (Anadara granosa) can be used as adsorbent of tin. Blood clam seashells was calcinated at 800 0C of ±9 hours. Blood clam seashells contained CaO . The aim of this study was to see potential of blood clam seashell ash as absorbent of tin. The research was conducted by contacting was tin ion and blood clam seashell ash with the variation of concentration. Tin analysis performed by using atomic absorption spectroscopy (AAS). The results showed that optimal absorption occurs at 30 mg/L, at 15 hours was 66,53%

    Broiler chicken bone consist of extracellular matrixes. The extracellular matrixes consist of organic and inorganic matrixes. The organic matrixes consist of substances containing complex protein molecules that surrounded by collagen fibers. Organic matrixes have used as a carbon source for chicken bones activated charcoal. Chicken bones activated charcoal was made from carbonization and activation processes, using activator substance Na2CO3 with variation of concentration 2.5%, 5%, and 7.5%. In this research, chicken bones activated charcoal was used to adsorb lead cation in solution Pb(NO3)2. The lead cation has been analyzed by Atomic Absorption Spectrophotometer (AAS), while the chicken bones activated charcoal was analyzed by Scanning Electron Microscopy (SEM), Energy Dispersive X - ray Spektroscopy (EDS), and Infra Red (IR). Adsorption (Q) of chicken bones activated charcoal on lead cation in a solution of Pb(NO3)2 with variation of concentration 10 mg/L, 50 mg/L, and 100 mg/L subsequently are 5.0578 mg/g, 24.7297 mg/g, and 49.9974 mg/g. Efficiency of chicken bones activated charcoal (E) are 99.5292% and 99.9947%
