Abstract

ne heavy metal, which is potential as pollutant, is cadmium that has been accumulated in soil and sediment. Although, cadmium is non essential element for plants, it is easily adsorbed and accumulated by various plants. The negative effect of cadmium on plants is that it can prevent the absorption of nutrition so that the plant growth will be inhibited and then the plant will die. Therefore, it is necessary to reduce the concentration of cadmium to be used as good growth media. Several methods of heavy metal accumulation, such as physical, chemical and biological methods, have been used, but the three methods have been considered as less effective methods. The use of plants to accumulate heavy metals in polluted soil is considered as a good method because the method is a safe method and can increase the soil fertility. In this research, accumulation of cadmium has been conducted by using Ipomeae reptans Poir. Result showed that the highest concentration that can be accumulated by I. reptans Poir was 3317.68 mg/kg of dried mass with the plantation time of 21 days. The increase of concentration in the growth media increased the cadmium concentration accumulated. The high accumulation of cadmium showed that I. reptans Poir is a hyperaccumulator plant for cadmium. The bioconcentration value was higher than 1, whereas the translocation factor was lower than 1 indicating that the accumulation mechanism was phytostabilization.Keywords : cadmium, accumulation, analysis, Ipomoae reptans Poir.

Abstract

Penelitian ini bertujuan untuk menentukan dampak jerapan campuran ion logam Pb(II) dan Zn(II) terhadap pertumbuhan mikroalga Chaetoceros calcitrans dan menentukan efisiensi penjerapan kedua ion logam dalam campuran. Pemaparan ion logam dengan berbagai variasi konsentrasi Pb(II) terhadap Zn(II)dilakukan setelah diperoleh pertumbuhan optimum C. calcitrans, yakni pada hari ke-9. Konsentrasi ion logam Pb(II) dan Zn(II) setelah pemaparan ditentukan dengan spektrofotometer serapan atom. Penambahan ion Pb(II) ke dalam Zn(II)membuat penjerapan ion Zn(II) oleh C. calcitrans turun dibandingkan dengan penjerapan ion tunggal Zn(II). Hal yang sama juga terjadi pada penambahan ion Zn(II)ke dalam ion Pb(II). Hasil penelitian menunjukkan bahwa ion Pb(II) lebih banyak terjerap oleh C. calcitrans dibanding ion Zn(II). Effisiensi penjerapan optimum ion Pb(II) sebesar 64,44% pada perbandingan konsentrasi Pb(II) terhadap Zn(II) 45 : 30 ppm sedangkan penjerapan ion Zn(II) yaitu 56,33% pada perbandingan konsentrasi Zn(II) terhadap Pb(II) 15 : 30 ppm.The main purpose of this research was to determine the adsorption effect of the mixture of Pb(II) and Zn(II) on the growth of Chaetoceros calcitrans and to determine the adsorption efficiency of the ions in the mixture. Exposure of Pb(II) and Zn(II)ions was conducted after the optimum growth of C. calcitrans was obtained, that is at the ninth day with the variation of the concentration ratio of Pb(II) to Zn(II). Concentration of Pb(II) and Zn(II) ions after exposure was determined by atomic absorption spectrophotometer. Addition of Pb(II) ion in solution Zn(II) ion resulted in the decrease of the Zn(II)ion adsorbed by C. calcitrans compared to the adsorption of the single ion of Zn(II). The same result was obtained when Zn(II) ion was added in Pb(II) solution. Results showed that the adsorption of Pb2+ ion by C. calcitrans was higher than that of Zn(II) ion. The maximum adsorption efficiency of Pb(II) ion was 64.44% at the Pb(II):Zn(II) ratio of 45:30, whereas that of Zn(II)ion was 56.33% at the Zn(II):Pb(II) ratio of 15:30.

Abstract

The use of epichlorohydrin to improve the stability of chitosan adsorbent has been carried out. The purpose of this study was to determine the stability of the chitosan adsorbent after modified into epichlorohydrin cross-linked chitosan and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. Adsorbent prepared by homogeneous gel formation of chitosan in acetic acid medium and then modified into epichlorohydrin cross-linked chitosan beads and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. Stability of the adsorbent was determined by calculating the percentage of insoluble material after stirring the adsorbent in nitric acid medium at pH 1, 2, and 3 for 12 hours. The results of FTIR spectra show a shift of the absorption band of chitosan were compared with epichlorohydrin cross-linked chitosan and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. The use of epichlorohydrin as cross-linked agent may increase the stability of the adsorbent to maintain the percentage of insoluble material by 89% at pH 3 for epichlorohydrin cross-linked chitosan adsorbent and 96% at pH 3 for ionic cobalt imprinted adsorbent chitosan  cross- linked epichlorohydrin.

Abstract

A molecularly imprinted polymers (MIP) can be synthesized using functional monomers and template molecules through polymerization with the aid of cross linker. In previous studies, MIP_TFMAA-co-EGDMA was synthesized using the main ingredient tryfluoromethylacrylic acid (TFMAA) as functional monomer, b-sitosterol as a template molecule and ethyleneglycol dimethacrylate (EGDMA) as cross linker. The ability of adsorption against the effects of pH and contact Time of MIP has been evaluated. Variations of pH standard solution b-sitosterol were 4, 5, 6, and 7, while the time variation used were 30, 60, 90, and 120 minutes. The data of b- sitosterol concentrations adsorbed by MIP_TFMAA-co-EGDMA because of the influence of pH and contact times were analyzed using high pressure liquid  chromatography (HPLC). pH5 gives the most influence on the adsorption capacity MIP_TFMAA-co-EGDMA against b-sitosterol. The number of b-sitosterol adsorbed on the pH was 1.0265 mg/g, while at 90 minutes was the best time for the MIP b- sitosterol adsorb as much as 1.3486 mg/g. Based on the adsorption kinetics study, the adsorption ability MIP_TFMAA-co-EGDMA against b-sitosterol in accordance with the pseudo second order kinetic model.

Abstract

Research about composition of superior nutrients, growth parameters, and best method to maximize production of biomass sea phytoplankton, Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. has been performed. The nutrients was named as MSSIP which were consist of following compositions: urea fertilizer, Arschat-M nutrient, Fe:Co:Ni metal ions (6 : 3 : 9 : 6 : 3). Methods used were identification and analysis of sea phytoplankton.  Determination of optimum growth condition, pure culture, and mass culture were using local raw materials-based engineered nutrients or MSSIP (M. Sjahrul-Syahruddin Kasim-Indah Raya-Paulina Taba). Determination of product density of sea phytoplankton biomass, analyses of carbohydrate content, and lipid biomass were done by using haemocytometer and microscope, Luff Schrol method, and soxhlet method (n-hexane as solvent), respectively. Morphology of phytoplankton was identified by using a digital camera microscope, SZ60/sZ60-61. Furthermore, to understand the effect of metal ions, Fe, Co, and Ni added into MSSIP nutrient, identification of nutrient before and after culturing process were done using XRF-Thermo-Fisher.  The results showed that Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. were suitable as raw materials  to produce biofuel. Those three phytoplankton contained 0,3095 g/L, 0,3782 g/L, and 0,3325 g/L biomass, 32,49%w/w, 31,58%w/w, and 29,81%w/w carbohydrates; and  25,95%w/w, 26,82%w/w and 24,53%w/w lipid, respectively. Best optimum condition of culture were salinity of 30-35%, temperature of 20-30 °C, pH of 8-9, initial density of 2.5 x 104 cell/mL, light exposure of 40 watt, and continuously aerated with CO2. Based on our study, sea phytoplankton, Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. have a high potency as source of bioethanol and biodiesel.Keywords: mass culture, superior nutrient MSSIP, sea phytoplankton biomass, Fe, Co, Ni metal ions
