The inactivation of E. coli at pH 7.4 was performed using: ultrasonication (14, 22, and 47 kHz), cecropin P1 (20 µg/mL), and a combination of both. Maya Fitriyanti, Ph.D and her colleagues found the treatment at 22 kHz, 8W for 15 min of exposure and a combination of ultrasound at higher frequency (47 kHz, […]

Controlling volatile organic compounds (VOC) is of utmost importance due to their adverse impacts on human health and environment. In this study, Prof. Fenny Martha Dwivany, Ph.D. and her colleagues investigate the influence of gold nanoparticles (AuNP) on TiO2-based structures, namely AuNP-decorated TiO2 thin films, Au@TiO2 core@shell structures, and AuNP-loaded TiO2 nanoparticles, using finite difference […]

A combination ozone-based advanced oxidation process is coupled with a nanobubbles generator for the generation of ozone nanobubbles (NB) utilized the same to treat the primary effluent acquired from textile wastewaters. Here Ir. Sri Harjati Suhardi and her colleagues find several key parameters such as chemical oxygen demand ammonia content (NH3), and total suspended solids […]

Excretion of cytoplasmic protein (ECP) is a commonly observed phenomenon in bacteria, and this partial extracellular localisation of the intracellular proteome has been implicated in a variety of stress response mechanisms. In response to hypoosmotic shock and ribosome stalling in Escherichia coli, ECP is dependent upon the presence of the large-conductance mechanosensitive channel and the […]

Plant-derived exosome-like nanoparticles (PDENs) could be a potential future functional food ingredient as their cross-kingdom communication abilities were reported to exert multiple health benefits. Macrophage and other cells have been reported to absorb PDENs in a manner regulated by the membrane lipid and protein profile and the intactness of the PDENs lipid bilayer. PDENs could […]

Cell suspension and callus cultures may serve as an alternative solution to provide a fast-growing plant material to produce artificial agarwood in a short period. Here, Dr. Ahmad Faizal, Dr. Rizkita Rachmi Esyanti, and their colleagues induced agarwood formation in callus cultures of Aquilaria malaccensis by application of crude mycelial extracts of Fusarium solani strains […]

Jayen Aris Kriswantoro, M.Si. and his colleagues conducted this work to study the effect of thermal alkaline pretreatment and zinc acetate-catalyzed methanolysis in biogas production from bioplastic in anaerobic digestion. The pretreated bioplastic with MtOH-ZnOAc performs efficient solubilization and produced 205.7 ± 6.9 mL/g CODadded, which is higher than thermal alkaline degradation. The mesophilic condition […]

The low hydrolytic stability of urea–formaldehyde adhesive leads to poor water resistance by the particleboard. Dr. Atmawi Darwis and his colleagues analyze the effect of hot-pressing temperatures and the addition of methylene diphenyl diisocyanate in UF adhesive on the physical and mechanical properties of PB. The first experiment focused on pressing temperature treatments including 130, […]

The application of self-eDNA in agriculture presents the potential to increase the resistance of banana plantlets. Karlia Meitha, Ph.D., Dr. Iriawati, Dr. Rizkita Rachmi Esyanti, and colleagues conducted this study that evaluated whether the eDNA from Fusarium oxysporum f. sp. cubense (Foc) could limit the growth of Foc itself while increasing the resistance of banana […]

This article explores linkages between food security, food sovereignty and foodways within the context of poor urban populations in Southeast Asia. Angga Dwiartama, Ph.D. and his colleagues situate the study within the vast array of literature concerning the (in)ability of the urban poor to access healthy and nutritious food due to factors of distance, price, […]
