The blend of standard Indonesian rubber (SIR-3L) and low density of polyethylene (LDPE) with a ratio of 50/50 (w/w%) had been prepared by varying the amount of divinylbenzene (DVB) and dicumyl peroxide (DCP). The properties of SIR-3L/LDPE blends had been characterized using scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), and mechanical properties. The addition of divinylbenzene and dicumyl peroxide affected the properties of SIR-3L/LDPE blends. [ABSTRACT FROM AUTHOR]

S-doped TiO2 photocatalyst has been prepared by the hydrothermal method at 180oC that assisted by the sol-gelel method and its photocatalytic activity was evaluated to reactive black 05. The obtained photocatalyst was characterized by XRD and SEM. The phase composition of S-doped TiO2 was influenced by the amount of sulfur. [ABSTRACT FROM AUTHOR]
