Abstract

Wilayah Cibinong-Citeureup terdapat banyak industri, berdebu, dan telah mengalami hujan asam. Salah satu dampak hujan asam adalah degradasi kualitas air sumur. Lebih kurang 75% penduduk di wilayah ini yang memanfaatkan air sumur sebagai air minum. Telah dipelajari distribusi dan dampak hujan asam terhadap peningkatan kadar Fe dalam air sumur. Monitoring air hujan dilakukan pada 30 menit pertama hujan pada 16 lokasi dari tahun 1999 sampai 2009. Data keasaman air hujan setiap tahun dipetakan menggunakan program sufer 6, selanjutnya dilakukan overlay dan diidentifikasi daerah yang mengalami hujan asam intensitas tinggi secara terus-menerus. Monitoring kadar Fe air sumur dilakukan pada 16 lokasi sumur dari tahun 1999 sampai 2009. Keasaman air diukur menggunakan pH meter elektronik, dan Fe ditentukan dengan metoda o-fenantrolin menggunakan spektrofotometer UV-VIS. Hasil penelitian menunjukkan bahwa daerah yang terus-menerus mengalami hujan asam intensitas tinggi (pH5,0) terjadi seluas 4 km2. Dalam daerah hujan asam intensitas tinggi ini keasaman air hujan terus meningkat dari tahun 1999-2009. Peningkatan keasaman air hujan menyebabkan leaching Fe ke dalam air sumur secara nyata (P 0,049, 95%).Kata kunci: Hujan asam,, leaching, Fe, air sumur, industri

Abstract

The processing of palm sago into flour produces unsightly brownish wastewater with high COD and TSS values and very low DO. Waste treatment to reduce waste parameter values can be done one of them by electrocoagulation method. This study was conducted to determine the effectiveness of processing sago wastewater by electrocoagulation and decreasing kinetics of TSS and COD. Electrocoagulation batch system was carried out using 5 x 10 cm aluminum electrode, 3 cm electrode distance. Application of voltage variations: 15; 18; and 20 volts with electrocoagulation time variation 15; 30; and 60 minutes. The results showed that the best electrocoagulation at 18 volts and 60 minutes time, namely the efficiency of reducing TSS and COD values respectively 89.17% and 58.28%, and can increase the DO value from 2.5 to 6.8 mg / L The kinetics of decreasing TSS and COD follow the one order with a constant decrease of respectively - 0.012 and -0.013 per minute.Key words: Electrocoagulation, palm sago liquid waste, TSS, COD

Abstract

Carbon has many benefits as an adsorbent, catalyst, drug delivery, energy, and it can produced from various resources, includinglignocellulosic biomass. One of the potential biomass for carbon material is bamboo. The particle size is usually inversely proportionalto the surface area and adsorption level; therefore, studying the particle size of activated carbon is essential. This research aims toproduce carbon and sulfonated carbon from andong bamboo to understand the effect of particle size on the characteristics andadsorption capacity. The method for this research was the pyrolysis of andong bamboo into sulfonated carbon bioproducts usingH2SO4 10N with variations in particle size of 60 and 100 mesh. The proximate analysis of activated carbon based on IndonesianNational Standard (SNI) No.06-3730-1995 includes moisture content, ash content, volatile matter content, and fixed carbon.Sulfonated carbon adsorption analysis was conducted on iodine, methylene blue, ammonia, chloroform, and benzene compounds.The result showed that the proximate parameters of activated carbon produced had met the SNI requirements. The adsorptioncapacity of activated carbon on the adsorption of iodine, methylene blue, ammonia, chloroform, and benzene was 421.71432.50mg/g; 20.3521.90 mg/g; 9.559.98 mmol/g; 10.1615.03%, and 4.63.83%, respectively. Based on andong sulfonatedcarbon data, it can be used as an adsorbent and renewable green catalyst.
