Aboveground Biomass and Carbon Stock Estimation Using UAV Photogrammetry in Indonesian Mangroves and Other Competing Land Uses

Aboveground Biomass and Carbon Stock Estimation Using UAV Photogrammetry in Indonesian Mangroves and Other Competing Land Uses

Dr. Elham Sumarga and his colleagues report a novel application using unmanned aerial vehicles (UAVs) to estimate and compare aboveground biomass (AGB) carbon stocks of mangrove forests with two alternate replacement commercial land uses (oil palm and coconut plantations) in Lubuk Kertang and Pulau Sembilan, North Sumatra, Indonesia. They generated high-accuracy digital surface models (DSMs) […]

Synergistic Effect of Ultrasound and Cecropin p1 Antimicrobial  Solutions in Deactivating Escherichia coli 0157:H7 with a Clyndrical Ultrasonic System

Synergistic Effect of Ultrasound and Cecropin p1 Antimicrobial Solutions in Deactivating Escherichia coli 0157:H7 with a Clyndrical Ultrasonic System

  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, […]

Optical absorption enchancement of TiO2 via plasmonic effect of gold nanoparticles in volatile organic compounds medium

Optical absorption enchancement of TiO2 via plasmonic effect of gold nanoparticles in volatile organic compounds medium

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 […]

Combination of Ozone-based Advanced Oxidation Process and Nanobubbles Generation Toward Textile Wastewater Recovery

Combination of Ozone-based Advanced Oxidation Process and Nanobubbles Generation Toward Textile Wastewater Recovery

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 […]

arfA antisense RNA Regulates MscL Excretory Activtiy

arfA antisense RNA Regulates MscL Excretory Activtiy

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 : A Concise Review on its Extraction Methods, Content, Bioactivities, and Potential as Functional Food Ingredient

Plant-derived Exosome-like Nanoparticles : A Concise Review on its Extraction Methods, Content, Bioactivities, and Potential as Functional Food Ingredient

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 […]

Elicitation of Secondary Metabolites in Aquilaria malaccensis Lam. Callus Culture by Crude Mycelial Extract of Fusarium solani and Methyl Jasmonate

Elicitation of Secondary Metabolites in Aquilaria malaccensis Lam. Callus Culture by Crude Mycelial Extract of Fusarium solani and Methyl Jasmonate

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 […]

Comparison of Thermal Alkaline Pretreatment and Zinc Acetate-catalyzed Methanolysis (MtOH-ZnOAc) for Anaerobic Digestion of Bioplastic Waste

Comparison of Thermal Alkaline Pretreatment and Zinc Acetate-catalyzed Methanolysis (MtOH-ZnOAc) for Anaerobic Digestion of Bioplastic Waste

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 […]

Influence of Isocyanate Content and Hot-Pressing Temperatures on the Physical-Mechanical Properties of Particleboard Bonded with a Hybrid Urea-Formaldehyde/Isocyanate Adhesive

Influence of Isocyanate Content and Hot-Pressing Temperatures on the Physical-Mechanical Properties of Particleboard Bonded with a Hybrid Urea-Formaldehyde/Isocyanate Adhesive

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, […]

Extracellular DNA of Fusarium oxysporum f. sp. Cubense as a Priming Agent for Inducing the Resistance of Banana Plantlets

Extracellular DNA of Fusarium oxysporum f. sp. Cubense as a Priming Agent for Inducing the Resistance of Banana Plantlets

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 […]
