Metode Penukar Ion dalam Penyisihan Ammonia Air Lindi Tpa Muara Fajar dengan Variasi Waktu Kontak dan Ukuran Tanah Lempung

Water into the garbage heap that comes from rain water, drainage channels, ground water, or other resources available around Muara Fajar landfill. Shelters Muara Fajar landfill leachate potential to generate waste that seeps into the ground and flows on the surface of the soil around the landfill. Leachate originating from shelters litter may result in increasing levels of environmental pollution in the vicinity of Muara Fajar landfill. Has done research methods ammonium ion exchangers in isolation Muara Fajar landfill leachate with contacts and measure the time variation of clay. This study aims to determine the parameters of pollutant removal efficiency of ammonia (NH3) by ion exchange method using clay and compares the characteristics of leachate treatment with quality raw KEPMENLH / 51/10/1995. This study uses clay size variations -5 + 10; -10 + 15; -15 + 20 mesh and 60 contact hours; 120; 180 minutes. The analysis shows that the leachate characteristics of NH3 concentration 38.69 mg / L indicating a high enough quality and more than raw (Minister of Environment Decree No. 51 of 1995). Having done the flow of leachate recovered pollutant concentrations decrease. Factors influence size variations of clay and contact time effect on the efficiency of reduction of concentration, the larger the mesh size (smaller diameter clay) then recovered the high efficiency of the concentration of pollutants. The results showed that the efficiency was high in clay size -15 + 20 mesh and 180-minute contact time gives the best removal efficiency of 91.12% NH3. While the efficiency of the lowest available in the size clay -5 + 10 mesh that is Ammonia of 17.13%. Cation exchange capacity of 105 earned meq / 100 g sample

Efisiensi Penurunan Kadar Natrium (Na+) dan Klorida (Cl-) pada Air Laut Menggunakan Tanah Lempung dengan Metode Penukar Ion

Research efficiency decreased levels of chloride ion in sea water by ion exchange method which utilitizes clay to do. The results of the initial analysis on the sea of chloride parameter indicates the concentration parameter exceeds the quality standards PERMENKES 416/MENKES/PER/IX/1990. The research uses an ion exchange column with a diameter of 2 inches and a height of 1,2 meters. Media used is sea water of Bengkalis and clay activated with KOH 2 M. Variation used is the flow rate and time of observation. The flow rate used are 140 ml/mnt, 160 ml/mnt, 180 ml/mnt and 200 ml/mnt and time of observation used are 1; 1,5; 2 hours. Concentration of chloride before research is 15.423 mg/L and after processing occurs at decreasing concentrations in each variation of chloride are 278 mg/L - 667 mg/L. This result shows that the ion exchange methode using activated clays are capable of removing of chloride concentration in sea water. Over all, the variation used in this research give effect to decreased of chloride in sea water. This is also evidenced in the removal efficiency of ion is 98,2 % - 95,7 %

Studi Timbulan, Komposisi dan Karakteristik Fisika dan Kimia (Proximate Analysis) Sampah Non Domestik di Kecamatan Tampan Kota Pekanbaru

Increased community activities will increase the amount of waste generated. Tampan District is one of a small town in the city of Pekanbaru can not be separated from tge garbage thing. This research aims to determine the generation, composition and physical characteristics and chemical (proximate analysis) non domestic garbage in Tampan of District Pekanbaru of City and generation data, composition and physical characteristics and chemical (proximate analysis) garbage are indispensable in designing of garbage management system. This research was conducted in 37 places including 19 institutions ( 8 schools, 5 offices and 6 health centers), 11 commercials garbage (6 stores, 1 markets, 2 restaurants and 2 hotels), 1 street sweeping and 6 industrials. Determination of non-domestic garbage generation is performed by interviewing and sampling of garbage at source based methode SNI 19-3964-1994 performed for eight day in a row. The results study of non-domestic generation of Tampan District Pekanbaru City in the amount of 0,38 kg/p/d in of weight unit or 4,13 l/p/d in volume unit. The composition of non domestic Tampan of District Pekanbaru of City solid waste domination of organic waste about 60,94% and anorganic garbage composition of 39,06%. For Physical characteristics such as specific weight is 0,23 kg/l and composition factor is 1,38 litre. The chemical characteristics (proximate analysis) are moisture 26,2%, volatile rate 54,6%, ash rate 9,5% and 10,0% fixed carbon rate

Penurunan Timbal (Pb) Air Laut Pulau Bengkalis Menggunakan Tanah Lempung dengan Metode Penukar Ion pada Variasi Tinggi Unggun dan Debit Aliran

The lack of clean water Sources in the regency of Bengkalis create communities that are the island's shortage of clean water. Moreover, during the dry season, services of PDAM Bengkalis was only able to supply about 10% of the number of existing communities. While Bengkalis island has abundant sea water availability. The purpose of research is to reduce the concentrations of Pb and pH as on the parameter using the method of ion exchange support using column height 1.2 m in diameter 2 inches of clays as well as Kulim size -10+15 mesh that has been on activation by using the HCI. A variation was used in this study is bed hight of 40 cm, 80 cm and 120 cm with discharge flow 80 ml/min, 100 ml/min, and 120 ml/min. Results of the analysis of effluents obtained efficiency for metal Pb is in the range of 41,44% - 89,35%. Metal concentrations of pb with the best reduction of 0,024 mg/L at bed hight variation 80 cm with discharge flow 80 ml/min and the pH from 8,5 to be 7,3. These concentrations already meets the quality of the raw water supply based on PERMENKES416/MENKES/PER/IX/1990. Cation Exchange Capacity (CEC) values obtained at the best efficiency of 78.6 Meq/100 gr with most types of minerals contained in the clay Kulim is a montmorilonit
