SINTESIS NANOPARTIKEL PERAK (AgNPs) MENGGGUNAKAN EKSTRAK DAUN PUTAT( Planchon…
Synthesis of silver nanoparticles (AgNPs) using putat leaf extract (Planchonia valida) had been carried out. AgNPs synthesis was carried out by varying the extract volume and heating temperature. The formation of AgNPs was observed by a color that change from yellow to brownish red and also confirmed by using a UV-Vis spectrophotometer which was marked by the appearance of a peak in the surface…

APLIKASI TINTA KARBON BINCHOTAN DENGAN SnO2 UNTUK LAPIS KATALIS DALAM MEMBRAN…
The research about the application of carbon dots from binchotan and SnO2 ink as catalyst layer in Membrane Electrode Assembly (MEA) of Direct Methanol Fuel Cell (DMFC) has been done. Carbon dots was prepared by electrolysis and sonication then ball milled with 40% and 60% SnO2 against carbon dots formed SnO2/C catalyst. Gas diffusion layer (GDL) were made with varied conductive components whic…

STUDI PENGOMPLEKSAN BORON DARI SENYAWA ASAM BORAT DENGAN PEREAKSI PIRIDOKSIN
Boric acid is a weak acid derivative of boron and the form of a white powder. This study aims to optimize the reaction between boric acid and pyridoxine through the effect of time temperature, and the effect of the amount of pyridoxine on the formation of boron complexes using the UV-Vis Spectrophotometry method and characterized by Fourier Transform Infrared (FTIR) and X-Ray Diffraction (XRD).…

PREPARASI KOMPOSIT (TiO2/C, V2O5/C, SnO2/C) DAN APLIKASINYA PADA DIRECT METHA…
Composite preparations (TiO2/C, V2O5/C, SnO2/C) and their application to Direct Methanol Fuel Cells (DMFC) have been carried out. Carbon sheets were made from gelam bark powder and then hydrothermally and pyrolyzed, while carbon ribbons are made from reduced carbon sheets. The results of the carbon was made into electrodes. The electrodes were characterized using the Cyclic Voltammetry (CV) met…

KONVERSI KARBON DIOKSIDA (CO2) MENJADI METANOL DENGAN METODE ELEKTROKIMIA MEN…
One of the ways to reduce excess CO2 on earth can be in the form of converting CO2 into methanol. The preparation and characterization of Cu2O-ZnO/C and Pt/C electrodes with their application in the conversion of CO2 to methanol by electrochemical reduction method using Gas Diffusion Electrode (GDE) as electrolyte membrane have been carried out. The electrodes were cast by spraying method and i…
