Asymmetric dense and thin membranes have been prepared from powders of perovskite oxide-type CaTiO3 without cracking by phase inversion method. Polyetherimide was used as a polymeric binder in the method. The resulting green membranes, composed of CaTiO3 powder and polyetherimide binder, were sintered at 890, 1100 or 1200 °C. The crystal phase of CaTiO3 was analyzed using X-Ray Diffraction (XRD). The XRD pattern of the synthesized CaTiO3 powder was matched with the reference indicating the formation of CaTiO3 structure. Sintering at 890 °C fails to form a strong membrane. Scanning Electron Microscope (SEM) images of the membranes showed that the membrane had the asymmetric structure with dense layer on one side and porous layer on the other side. The pores in the porous layer were both finger-like and sponge-like structure. The mechanical strength of the membranes, which were determined by Vickers micro hardness method, varied from 3.5 to 25.8 Hv. The strongest membrane without any crack was resulted from sintering at 1200°C with hardness values between 19.4 and 25.8 Hv. Thermal expansion coefficients of the asymmetric membranes sintered at 1100 and 1200 °C, measured with Thermomechanical Analyzer (TMA), were 10.82 × 10-6 and 12.78 × 10-6.C-1 respectively.

Binuclear complex, [N(n-C4H9)4][MnIIFeIII(ox)3] (ox=oxalate), has been synthesized and characterized. Binuclear complex with formula of [N(n-C4H9)4][MnIIFeIII(ox)3] was synthesized by forming precursor K3[Fe(ox)3] which was followed by adding manganese chloride and tetrabutyl ammonium chloride. Characterization of the complex was made by microanalysis, FT-IR spectroscopy, x-ray diffraction and Magnetic Susceptibility Balance. Magnetic moment of binuclear complex [N(n-C4H9)4][MnIIFeIII(ox)3] is 7.81 BM. The compound has higher magnetic moment than the previously reported compound with different organic cation, [N(n-C5H11)4][MnIIFeIII(ox)3]. This behavior might be associated with the decreasing range among layers on polymeric network.

CRYSTALLINE PHASE REACTIVITY IN THE SYNTHESIS OF FLY ASH-BASED GEOPOLYMER Lukman Atmaja; Hamzah Fansuri; Anggaria Maharani

Publisher : Universitas Gadjah Mada

Aluminosilicate, alkaline solution and fly ash from a power plant have been used to synthesize geopolymer at ambient temperature. SiO2/Al2O3 mole ratio of the starting materials was varied by the addition of pure, insoluble corundum and quartz. The geopolymer exhibited some differences in the ratio of initial reaction mixtures and that of final products. The corundum gave no influence to the compressive strength while the quartz at SiO2/Al2O3=4.0-6.0 produced significant change in the strength. The highest compressive strength achieved was 65 MPa. XRD using analysis Rietveld method proved that quartz has been found both in starting materials as well as in the geopolymer indicating the involvement of crystalline phases, to some extent, in geopolymerization process.

THE EFFECT OF PHOSPHORUS ADDITION ON THE ACTIVITY OF BISMUTH MOLYBDATE CATALYST FOR PARTIAL OXIDATION OF PROPYLENE TO ACROLEIN Hamzah Fansuri; Gia Hung Pham; Sandra Wibawanta; Dong-ke Zhang

Publisher : Universitas Gadjah Mada

In order to examine the effect of phosphorus addition on the activity and selectivity of bismuth molybdate catalysts for partial oxidation of propylene to acrolein, three modes of phosphorus addition were performed. The three modes of Preparation were performed by (1) adding phosphorus into a-Bi2Mo3O12 to obtain Bi2PxMo3Oy, (2) inserting phosphorus on bismuth sites to obtain Bi2-xPxMo3Oy, and (3) inserting phosphorus on molybdenum sites to obtain Bi2PxMo3-xOy. Four major phases of bismuth phosphomolybdate were detected as the result of the phosphorus addition, namely a-Bi2Mo3O12, Bi9PMo12O52, MoO3, and BiPO4. Experimental results showed that the catalysts solely containing BiPO4 and/or MoO3 have very low activities for partial oxidation of propylene to acrolein. Meanwhile, catalysts containing a-Bi2Mo3O12 and Bi9PMo12O52, together with either MoO3 or BiPO4 showed on average the same activities as a-Bi2Mo3O12 and one of them (combination of a-Bi2Mo3O12, Bi9PMo12O52 and MoO3) has better performance than a-Bi2Mo3O12 at lower temperatures. The presence of the oxygen donor phase, i.e. BiPO4 and MoO3, are believed to play a key role for the high activities of bismuth-phosphomolybdate catalysts. However, at higher temperatures, the presence of oxygen donor reduces the catalyst selectivity to acrolein.

CATALYTIC PERFORMANCES OF Fe2O3/TS-1 CATALYST IN PHENOL HYDROXYLATION REACTION Didik Prasetyoko; Cholifah Endah Royani; Hamzah Fansuri; Zainab Ramli; Hadi Nur

Hydroxylation reaction of phenol into diphenol, such as hydroquinone and catechol, has a great role in many industrial applications. Phenol hydroxylation reaction can be carried out using Titanium Silicalite-1 (TS-1) as catalyst and H2O2 as an oxidant. TS-1 catalyst shows high activity and selectivity for phenol hydroxylation reaction. However, its hydrophobic sites lead to slow H2O2 adsorption toward the active site of TS-1. Consequently, the reaction rate of phenol hydroxylation reaction is tends to be low. Addition of metal oxide Fe2O3 enhanced hydrophilicity of TS-1 catalyst. Liquid phase catalytic phenol hydroxylation using hydrogen peroxide as oxidant was carried out over iron (III) oxide-modified TS-1 catalyst (Fe2O3/TS-1), that were prepared by impregnation method using iron (III) nitrate as precursor and characterized by X-ray diffraction, infrared spectroscopy, nitrogen adsorption, pyridine adsorption, and hydrophilicity techniques. Catalysts 1Fe2O3/TS-1 showed maximum catalytic activity of hydroquinone product. In this research, the increase of hydroquinone formation rate is due to the higher hydrophilicity of Fe2O3/TS-1 catalysts compare to the parent catalyst, TS-1.

Polymeric membrane-based-Styrofoam waste in the form of a thin sheet was successfully prepared by a phase-inversion technique in different final solidification treatments, namely, immersion and evaporation. This study aims to identify the effects of different solidification processes on membrane properties such as hydrophobicity, pore configuration, porosity, and membrane temperature stability. Characterization was carried out using contact angle, SEM, FTIR, TGA, and porosity tests. The results showed that an increase in Styrofoam 18-30 wt.% in dimethylformamide (DMF) as solvent decreases the hydrophobicity by 9.5%. The average contact angle of 62–80° indicated that the obtained membrane was prepared by immersion treatment. The membrane subjected to evaporation treatment was hydrophobic. Moreover, the microscopy image shows that the immersed membrane was denser than the evaporated membrane. This showed that a higher exchange rate between the solvent and non-solvent (water) produced a tight membrane than free evaporation in air. The polystyrene membrane from Styrofoam exhibited excellent temperature stability up to 350 °C. In addition, the mechanical strength was affected by employing different solidification processes. The obtained results were also successfully tabulated from a statistical point of view to validate the conclusions. The following information can provide basic knowledge for modifying membrane-based-Styrofoam to optimize zero-waste goals.

Piperine obtained from Javanese long pepper extract is an essential compound, but it has the disadvantage of being insoluble in water, so its bioavailability is low. One of the efforts that can be made to overcome this is by changing the size to nano, such as making nanoemulsion preparations. The study aims to determine the effect of VCO:Tween 80 ratio and homogenization time on nanoemulsion characteristics of Javanese long pepper extract. The research method utilized a completely randomized design by treating VCO:Tween 80 ratio and homogenization time. The research parameters included an organoleptic, percent transmittance, pH, viscosity, piperine content, particle size, polydispersity index, and zeta potential. This research resulted in a percent transmittance value of 97.05-99.55%, pH 4.89-5.56, viscosity 0.35-0.76 cP, piperine content 6.29-12.25%, particle size 41.482 nm and 266.62 nm, polydispersity index 0.7446 and 0.4358, zeta potential -4.443 mV, and -2.166 mV. The study is expected to be a reference in utilizing piperine content to benefit spices and medicines.
