POLYMER ELECTROLYTE MAKING FROM EUGENOL AND DIRECT METHANOL FUEL CELLS

The continuous use of hydrocarbon fuels results in fossil fuel supply as natural resources that cannot be renewed. Another problem that is also caused is the occurrence of environmental pollution and global warming. Therefore, it is necessary to look for alternative energy that is sustainable and economical with low emissions. One alternative energy that has received attention to be developed is the fuel cell. A fuel cell is an electrochemical device that directly converts chemical energy from a redox reaction into electrical energy [1]

Peningkatan Kualitas Produksi UKM Percetakan di Karangpilang Surabaya dan Krian Sidoarjo

Mitra 1 (Purnama Advertising) is a printing business engaged in printing and graphic design, owned by Mr. Purnomo. Business location Purnama Advertising is very strategic close to the highway, due to many people skipped. Mitra 2 (Smart Jaya) owned by Mr. Hidayat handles a very simple print design. Smart Jaya business location is very strategic close to the school. The problems faced by Partners 1 and Partner 2 are constrained in the field of online marketing, due to the limited cost of the Partners. The purpose of the devotion activity is to develop an independent printing business and have a broad insight on print design and graphic design. The solutions offered from the devotion activities are providing printing machines and hot press machines, mentoring media marketing, production management and marketing training. The outcomes of the IbM program are scientific publications in ISSN Journals, national seminar publications, and online promotional media

Sulfonated PEI membrane with GPTMS-TiO2 as a filler for potentialdirect methanol fuel cell (DMFC) applications

This study addresses the effect of 3-Glycidyloxy propyl trimethoxy silane (GPTMS)-modified titanium dioxide (TiO2) which composited sulfonated polyetherimide (SPEI) as a proton exchanger on direct methanol fuel cell (DMFC). The membrane fabrication was mainly based on phase-inversion method after GPTMS-TiO2 and SPEI were prepared separately. Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electronic microscopy (SEM), ion exchange capacity (IEC), proton conductivity, water uptake, methanol permeability, and mechanical properties were utilized to characterize and measure their physical and thermal stability. As the result, high water uptake and IEC performance were achieved using the fabricated membrane. Lower methanol permeability was observed compared to Nafion 117 membranes. The membrane performance showed improvementusing 20 wt% SPEI and 5wt% TiO2-5 wt% GPTMS with an optimum result of 3 times lower in terms of methanol uptake and methanol permeability with proton conductivity of 21 mS.cm-1than the remaining membranes and Nafion. Thus, the obtained results of SPEI/TiO2-GPTMScan be promoted as a novel polymeric membrane for DMFC

Preparation and Characterization of Nanofiltration Membrane for Water Treatment

Membrane technology has been developed significantly because it could be applicated on several fields. Therefore, in this study we report the manufactures of cellulose acetate nanofiltration membranes. The membranes were fabricated from dope solution consisting of cellulose acetate, poly ethylene glykol (PEG), distilled water, and acetone using a simple dry/wet phase inversion process. Production condition used included evaporation times of 10, 15, and 25 seconds, PEG addition of 2.5%; 3.5%; and 5%, with and without non-solvent addition of 1% distilled water in order to fabricate a high performance nanofiltration membrane. The mambranes performance that are based on percentage of rejection of barackish water and multivalent ion Ca2+, flux and mechanical strength of membrane. Generally, the percentage rejection and mechanical strength were found to increase and the flux were decrease with increasing of eveporation times. In the other side, the percentage of rejection, flux and mechanical were found to increase with increasing PEG addition. The percentage of rejection and mechanical strength were found the best in membranes with addition non-solvent of 1% distilled water, but the fluxes were the least. An optimimum membranes performance were found at compotition of dope solution composition consisting of 23% CA, 5% PEG, 25 seconds evaporation times and 1% distilled water
