| Abstract: |
This study investigated the potential of pineapple waste and treated pineapple waste as an adsorbent for removal of lead (Pb2+) from aqueous solution. The raw materials used are mixed pineapple residues such as stems, leaves and fruit. The treated pineapple waste was prepared using sodium hydroxide (NaOH). Both untreated and treated pineapple wastes are characterized using Fourier Transform Infrared (FT-IR) analysis and serial series of adsorption experiment were performed to evaluate the suitability of product as an adsorbent material. The influence of pH (2, 4, 6), contact time (15, 30, 60, 90 minutes), and the temperature (30, 60, 900C) on adsorption experiment were also evaluated. Pineapple waste treated with NaOH was found has higher adsorption efficiency for lead ions average at 85.88% than untreated ones by about average at 52.57%. The optimum contact time is at 60 minutes. For pH effect, the biosorption capacity increases sharply from pH 2.0 to pH 4.0 while slightly decreased at pH 6.0 due to the formation of soluble hydroxyl complexes. With increasing the temperature, the Pb2+ removal efficiency also increased from 74.31% to 87.28%. The results of this study revealed that pineapple waste is a suitable to remove Pb2+ metal ions from aqueous solution and can be applied for wastewater treatment.

| Abstract: |
Benefit for mankind is the key for intensive scientific innovation. In this belief, the research in field of biofuels is one such to create an ecofriendly environment. The work presented here includes the study on the influence of variation of compression ratio(CR) on engine performance, combustion and emissions for the selected biodiesel fuels namely Vateria Indica Oil Methyl Ester (VIOME) B20, Waste Cooking Methyl Ester(WCOME) B20 and W10V10 (Hybrid of VIOME B10 and WCOME B10)along with neat diesel. The main focus is on VIOME due to the reason being very little research is done on the same. The compression ratio levels selected are 17, 17.5 and 18 where 17.5 is standard for the engine design to work on diesel. The increase of the compression ratio favored to increase the brake thermal efficiency (BTE) and reduction in brake Specific fuel consumption (BSFC). The combustion characteristics enhanced at CR 18 due to the temperature assistance. The emissions did not show a significant improvement. The NOx levels were observed to be high whereas the CO levels dropped due to the better combustion.
