Abstract Â The reduction of land that used for land-based mining caused the shift of mining from land-based mining to off-shore mining, that used to namedFloating Inkonvensional Mining. This type of mining caused waters quality degradation.This research aimed to analyze Pb, Cd, and Zn content in water, sediment, and biota so that the value of the bio-accumulation factor can beanalyzed.The locations determination was conducted by using purposive random sampling method and the implementation was using GPS Garmin 60 in June 2013. The sea water sampling was using the water sampler, the sediment sampling was using paralon pipe, the plankton sampling was using the plankton-net, the shellfishes sample was collected from the fishermen, and the chavies and squids sample was got from Baganin the waters of Pulau Panjang.The analysis of the metal in water and sediment was refer to the prosedur standard method (APHA, 2005), while the analysis of the heavy metal in the planktons and the tissue of the biota was refer to SNI 2354.5:2011. The content of metal was compared with the quality standard that have been determined.The Cd and Zn content in water was under the sea water quality standard for sea biota. The Pb in the waters have been exceeded the quality standard that have been determined in Kepmen LH no. 51 Tahun 2004.The Pb, Cd, and Zn content in sediment wasÂ lower and far away from the quality sandard that have been determined by Norwegia and Irlandia. The heavy metal content in Anadara granosa, Stolephorus, sp, and Loligo chinensis, gray which were got chaught in the waters of Batu Belubang was lower thanthe national quality standard (SNI 2731.1:2010). The value of bio-concentration factor (BCFs-w) showed that the highest ability of sediment to accumulate Pb was existed in station number 2, i.e. 10,037 l/kg. The value of bio-concentration factor (BCFo-s) showed the plankton ability to accumulate Pb in sediment (1,26) was higher than its ability to accumulate Zn in sediment (1,22), while its ability to accumulate metal in water (BCFo-w) was as high as 8,275 in station number 2. The value of bio-concentration factor (BCFo-s) showed that the shellfish, chavies, and squid ability in accumulating metal in sediment was as high as 0,713; 0,564 and 0,703. The value of bio-accumulation of shellfish in sediment was higher because sediment was the habitat of shellfish.Floating Inkonvensional Mininghave contribution in spreading heavy metal, that was contained in the soil, to the waters. This condition needs supervision to control TI Apung growth in this location so that does not pollute the waters.

Popularity of conducting polymers are become widely known and researches for practical application also has been done. In order to developed a continuous process for industrial scale,Â we have proposed a spray pyrolysis method to synthesis a flexible conductive film of Poly(3,4-ethylenedioxythiophene) poly(styrene sulfonate) (PEDOT:PSS) on poly(ethylene terephthalate) (PET) and annealed at different temperatures and spray distances. The optimum condition that resulting a best morphology was anneal at 90oC and 20 cm distance with electrical conductivity 4.5 S/cm. It was found that annealing at temperature higher than 90oC will resulting a stress to a film and formed crack due to a different thermal expansion, while at the distance higher than 20 cm resulting a loss of PEDOT:PSS droplets. IR spectra shows that there is no any sign of PEDOT:PSS degradation even at 110oC. SEM analysis also show that the thickness is well distributed and there is no any sign of crack formedArticle History: Received February 24th 2017; Received in revised form May 16th 2018; Accepted May 20th 2018; Available onlineHow to Cite This Article: Tarmidzi, F.M. and Sasongko, S.B.

The objective of this research was to study a kinetic model of biodiesel production from waste cooking oil assisted by ultrasound power. The model considered the biodiesel production process as a 2nd order reversible reaction, while its kinetic parameters were estimated using MATLAB, based on data extracted from Hingu, et al. [1]. The data represented experiments under low-frequency ultrasonic wave (20 kHz) and variations of temperature, power, catalyst concentration, and alcohol-oil molar ratio. Statistical analysis showed that the proposed model fits well to the experimental data with a determination coefficient (R2) higher than 0.9.

Drying with air dehumidification with solid adsorbent improves the quality of food product as well as energy efficiency. The natural zeolite is one of adsorbent having potential to adsorb the water. Normally, the material was activated to open the pore, remove the organic impurities, and increase Si/Al rate. Hence, it can enhance the adsorbing capacity. This research studied the activation of natural zeolite mined from Klaten, Indonesia as air dehumidification for food drying. Two different methods were used involving activation by heat and NaOH introduction. As indicators, the porosity and water loaded were evaluated. Results showed both methods improved the adsorbing capacity significantly. With NaOH, the adsorbing capacity was higher. The simple test in onion and corn drying showed the presence of activated natural zeolite can speed up water evaporation positively. This performance was also comparable with Zeolite 3A

Indonesia is a country that has a lot of Ilmenite (FeTiO3), but as yet only plays the role of an exporter of this important raw material. The exact conditions for processing Ilmenite into products for sand proficiency levels as well as industrial raw material pigments are not yet known. Improved grade of titanium dioxide as a separation process should be supported by research on natural raw material sources that can be used. One raw material is waste zircon sand in Central Kalimantan (Borneo), which contains 80-90% of Ilmenite. The purpose of this research was to determine the effect of aeration time and concentration of salt catalyst (NH4Cl) on the transformation rate of iron (Fe) into iron oxide (Fe2O3), where iron oxide and titanium dioxide was separated by acid leaching process to produce pure titanium dioxide. The titanium oxide purification process adopted from Becher process which is the process of oxidation, reduction, aeration, leaching, stripping, and calcination. In this experiment, the fixed variables used were time of oxidation and reduction of 3 hours and time of calcination of 3 hours. The changing variables used were aeration time of 2, 4, 6, and 8 hours; and concentration of salt catalyst (NH4Cl) of 1%, 2%, and 3%. XRD (X-ray Diffraction) qualitative analysis and GSAS (General Structure Analysis System) quantitative analysis on the results showed an increase in TiO2 content on all the variables. The process of increasing TiO2 content at a variable of 1% NH4Cl gave the best result. The greater the concentration of NH4Cl catalyst, the smaller the TiO2 increase. The best time for improving the grade of TiO2 was 4 hours, proven by a very effective transformation of Fe into Fe2O3. The result of research gave a potential concentration of titanium dioxide was 45.86% with aeration process time of 4 hoursand NH4Cl concentration of 1%.

Fly ash is a solid waste product of coals combustion. Potential areas for the utilization of fly ash is in cement production, butthe unburned carbon in fly ash adversely affects the quality of final product (Miura, K 2010), and this research is a way to separate unburned carbon from fly ash using a flotation column with DAF system(Dissolved Air Flotation). This research is also aim to calculate the unburned carbon using LOI test (Lost On Ignition). This method, used to calculate unburned carbon content, will estimate energy potential from fly ash recycles.The variable that used in this research is flotation times (15, 25, 35, 45, and 55) minutes and feed concentrations (10, 20, 30, 40, 50) gram/liter. The result shows that the biggest of average % reduction of LOI is 55.1782% at 55 minutes of time variable. For concentration variable there is no significant differences because the average % differences is 7.5395%. Therefore the most effective variable in this research is 50 gram/liter of concentrations and 55 minutes of flotation times.
