Abstract

Abstract. Dragon fruit peel is a material that is abundant and cheap. The material has been used as an adsorbent in the biosorption process for the removal of metal ions of Cd(II) from wastewater. Biosorption of Cd(II) ion by dragon fruit peel was done on the variation of contact time, pH and concentration. The concentration of metal ions Cd(II) before and after adsorption was determined using Atomic Absorption Spectrophotometer (AAS). Results showed that the optimum time was 20 minutes and the optimum pH was 5. Adsorption capacity was studied by both isotherm adsorptions of Langmuir and Freundlich. Results showed that the biosorption of Cd(II) ion using dragon fruit peel full filled the isotherm Langmuir model with the biosorption capacity (Qo) of 36,50 mg/g. The functional group involved in metal ion biosorption of Cd(II) by the peel of dragon fruit is a hydroxyl group (-OH).

Abstract

Nickel is one of the heavy metals which is very dangerous because it is carcinogenic and can cause a variety of acute and chronic diseases. Biosorption is one alternative method for the removal of heavy metals from the environment using a biomaterial called biosorbent. Biosorption of Ni(II) ion using cacao fruit peel (Theobroma cacao) with variation of contact time, pH and concentration has been investigated. The concentration of Ni(II) ion before and after adsorption was determined by Atomic Absorption Spectrophotometer (AAS). The result showed that cacao fruit peel (Theobroma cacao) was able to adsorb Ni(II) ion and the optimum biosorption occured at a contact time of 10 minutes and at a pH of 5. Langmuir and Freundlich isotherm models were used to study the adsorption isotherm. Biosorption of Ni(II) ion by cacao fruit peel (Theobroma cacao) fulfilled the Langmuir isotherm with a biosorption capacity of 0,21 mmol/g. The functional groups involved in the  biosorption of Ni(II) ion by cacao fruit peel (Theobroma cacao) are –OH and N-H.

Abstract

A study on synthesis and characterization of nanoporous carbon derived from sugarcane bagasse   (Saccharum   officianarum)   by   ultrasonik   irradiation   using   ZnCl2     activator   for electrochemical capasitor application has been investigated. Nanoporous carbon is a basic material for the electrode in the electrochemical energy storage. Nanoporous carbon has been synthesized based on three-steps procedures, i.e. carbonization in temperature of 350 0C, silica extraction, and activation using ZnCl2  with ultrasonic irradiation. Activated carbon with irradiation showed an increasing in intensity of the –OH functional group stretch at wave number of 3419,79. The results of XRF analysis showed the highest content of oxide compound in the activated carbon was ZnO as 97,06%, and result of XRD analysis showed that activated carbon has both amorphous and crystalline. The result of SEM analysis showed that the pores evolvement of irradiated activated carbon was better than un-irradiated activated carbon, with diameter of the pores 1,5 to 2 µm. The surface area of the carbon in optimum temperature of 30 oC for 60 minutes was 171, 2802 m2/g and the energy storage capacity was 0,3284 x 10-5 F/g.
STUDY OF COMPOUNDS FROM EXTRACT OF Melochia umbellata (Houtt.) Stapf var. Degrabrata K. (PALIASA) LEAVES THAT HAS POTENTIAL AS ANTIBACTERIAL Selfi Wullur; Firdaus Firdaus; Hasnah Natsir; Nunuk Hariani Soekamto

Abstract

Determination of antibacterial activity of each extract of M. umbellata (Houtt.) Stapf var. K. degrabrata leaves has been conducted against three strains bacteria Escherichia coli, Staphylococcus aureus, and Shigella dysenteriae by using amoxicillin as a positive control and DMSO as a negative control. Agar diffusion method has been used with MHA medium (Muller Hinton Agar) on variation concentrations of each extract were 2500 ppm, 5000 ppm, 10,000 ppm, and 20,000 ppm N-hexane extract was the most active extract against S. aureus with zone of inhibitions were 10.50 mm, 10.80 mm, 11.00 mm and 11.45 mm, respectively. The most active extract against S. dysenteriae was ethyl acetate extracts with zone of inhibitions were 9.36 mm, 11.55 mm, 11.58 mm and 17.70 mm, respectively. Isolated compound from n-hexane extract was first compound as white powder with a melting point of 75-77 °C which was identified as 1-Tetracosanol and second compound was obtained in the form of a yellow paste which was identified as steroid compound that had long conjugated substituent. These compounds were elucidated based on the data of IR, UV-Vis, 1H-NMR, and 13C-NMR.

Abstract

Phytochemical analysis, toxicity test by the   brine   shrimp   lethality   test   (BSLT) against Artemia salina L, and antioxidant activity evaluation of the extracts of  Kerehau leaves (Callicarpa longifolia  Lam.)  have  been  carried  out.  The  ethanol  extract  obtained  from  Kerehau  leaves  was concentrated by using a rotary vacuum evaporator. Furthermore, the crude extract was fractionated with n-hexane and ethyl acetate solvent, successively. The phytochemical  analysis of crude extract constitutes alkaloids, phenolics, flavonoids and steroids. n-hexane fraction contains alkaloids, flavonoids and steroids and ethyl acetate fraction contain alkaloids, phenolics and flavonoids. n-Hexane fraction exhibited highest toxic activity with LC50  value 90.05 ppm against Artemia salina L and ethyl acetate fraction has the highest antioxidant activity with IC50 value 38.94 ppm compared with other extracts.

Abstract

Eosin is one of the dyes commonly used in the industry and has the potential to cause pollution of the water environment. The Eosin pollution treatment methods used in this study was the adsorption method using humin fraction obtained from the peat land comes from Kalimantan. From the research data showed that the adsorption of eosin in humin result of washing with HCl / HF optimum at pH 4 and a contact time of 60 minutes with the adsorption-order rate was 8,4 x 10-3 min-1
