Abstract

Slag is defined as a waste material produced from iron ore smelting process in blast furnace. The slag was derived from Research Center for Mineral Technology located in Tanjung Bintang Lampung Selatan with particle size of 80,100, and 120 mesh. The percentages of slag used as cement substitution were 10%, 20%, and 30% from total volume. Test pieces was made by compressing all mixture material in 50 x 50 x 50 mm cubical mortar mold. Physical test of mortars, such as : porosity test, density test and compressive strength test were performed. Based on physical test of samples, it was shown that the higher ratio of slag used in cement substitution gives higher mortar porosity. Substitution of 10% slag with size of 100 mesh produced the porosity of 3.45%, while the substitution 20% and 30% slag with the same size, produced 5.08% and 5.76% porosity, compared with the standard of mortar which was 5.12%. The compressive strength test with 10% slag substitution was 19.3 Mpa, while 20% substitute slag gave the compressive strength of 19.1 Mpa and 30% substitute slag has compressive strength value of 18.7 Mpa. The standard mortar is 17.2 Mpa. However, beside of slag substitution ratio, the slag particle size also affected the compressive strength and porosity. Based on the results explained, the substitution of slag as a substitute for cement in mortar strength was still above the mortar standard.

Abstract

Waste water from textile industry contain pollutant whit in certain concentration. To protect the environment and water bodies, wastewater containing pollutant must be treated before discharging into the environment. Anaerobic biological treatment has been used as a method in treating textile industry waste water. Several factors of conventional anaerobic treatment needs to be repaired in order to improve the performance of treating wastewater. A selected microorganisms as inoculum was expected to increase effectivity of waste water biodegradation. In this study a selected microorganisms was used as inoculum in the form of immobilized and free cells in anaerobic treatment of waste water from textile industry and compared with conventional sludge. Results from this study show that selected-immobilized microorganisms achieved the best performance due to its stability and efficiency in removing pollutant in the waste water. Mean while microorganisms in the form of free cells got the lowest performance in treating waste water, estimated due to its sensitivity of environmental conditions and having low mechanical strength of biomass.Immobilized cells succesfully treated waste water from textile industry, removal of pollutant in suspended solid parameter  reached on 93,78% mean while, in oil grease, BOD5 and COD parameter reached on 99,13%, 81,54% and 64,94% respectively. Pollutant in amonia parameter has not been fully treated in this experiment due to condition of the experiment system was anaerobic instead of aerobic.

Abstract

Surfactants have been widely used in many industries, one of them is sodium dodecylbenzene sulfonate (DBS) which is a major component used in the manufacture of detergents and considered as toxic material. Various methods have been undertaken to reduce DBS content in water. One of them is adsorption, which is known as the most effective and environmentally friendly method so far. Our previous study has successfully synthesized an adsorbent C?3,4?dimethoxyphenylcalix[4]resorcinarene triphenylphosphonium chloride (CRP). The aim of this study is to investigate the adsorption of DBS by CRP. Adsorption studies were carried out using the batch methods at different acidity, contact time, and initial DBS concentration and analyzed using UV?Visible, FTIR, and SEM?EDX spectrophotometer. The results showed the optimum condition of DBS adsorption was at pH 8, contact time 120 min, and DBS concentration 40 mg/L. The maximum capacity for the adsorption process was 12.93 mg/g. The rate of adsorption was found to follow the pseudo second?order kinetic model and the Langmuir adsorption isotherm. The mechanism was a chemisorption that occur in monolayer (?G? ads = ?24.87 kJ/mol).

Abstract

Dry Rubber Content (DRC) describes a rubber particle percentage in natural rubber latex. In this paper, the relation between forward light scattering profiles of natural latex and rubber contents is reported for dry rubber content latex. The profile, characterized by Full Width at Half Maximum (FWHM), is increasing linearly with respect to rubber content. The measurement was performed immediately after latex being tapped with necessary addition of acetic acid. This addition was meant to prevent latex coagulation. There is a high linear correlation between DRC and FWHM of both domain: one and two dimension. This is indicated by correlation factor which are higher than 0.9 for both of domains and sufficient in DRC determination.

Abstract

The performance of Horizontal Sub-Surface Flow Constructed Wetland (HSSFCW) to remove high ammonia content in catfish processing wastewater was investigated. A rectangular HSSFCW with 6 m long, 3 m wide ,1 m deep and divided into 3 compartments was used. Gravel beds were used as medium. Canna sp, Heliconia sp., and Papirus sp. were planted with plant density 10 plants per m2. The result showed that removal of ammonia was 67-87%, nitrite was 26-96%, nitrate was 35-99%. Ammonia removal relies on the efficient nitrification that requires sufficient amount of oxygenand organic carbon source to obtain optimum removal.
