Extracellular polymeric substances (EPS) can be used as an effective biosorbent for removing heavy metals from soil washing effluent. In this research by Ir. Sri Harjati Suhardi and her colleagues, Bacillus subtilis was used as an EPS-producing bacteria with a yield of bound EPS of 0.6 mg/g biomass with protein and polysaccharide content of 199 […]

Digital technologies have transformed our approach to food and agriculture, promising to revolutionize global food production while minimizing environmental impact. Angga Dwiartama, M.Si., Ph.D., and his team propose a model of digitalization based on assemblage theory, comprising three dimensions: project-based digitalization, everyday digitalization, and reflexive digitalization. These dimensions represent various relationships between practices, representations, and […]

This themed issue sets out to explore the everyday dimension of digitalization, in the specific context of agri-food systems. Angga Dwiartama, M.Si., Ph.D. and his colleagues propose a collection of papers that contribute to opening new approaches to digitalization in food and agriculture. The various forms of everyday digitalization that are presented in this symposium […]

In this study, Dr. Muhammad Yusuf Abduh, MT. et al. examined how microclimate conditions affect the activity of Tetragonula laeviceps, Tetragonula biroi, and Tetragonula drescheri in Modular Tetragonula Hives for crude propolis production. They also studied the impact of cultivating these species with P. merkusii resin on propolis productivity, and different extraction methods on propolis […]

Dr. Indra Wibowo, Dr. Ahmad Faizal, and their colleague explored the production of oleanane-type saponins produced by the genus Talinum. The first aim of the study was to isolate the probable gene encoding bAS, a key enzyme involved in the cyclization of 2,3-oxidosqualene producing the backbone of the oleanane-type saponin β-amyrin and characterize the gene […]

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) […]

  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 […]
