Together with Syed S., Helen J., and team, Sri H. Suhardi examined an HF-sAnMBR-DHS system for enhanced RB5 diazo dye synthetic textile wastewater treatment. Phase-1 (51 days) operated with natural aeration, while Phase-2 (66 days) applied intermittent forced aeration (2 L/min, 5 min ON/OFF cycle) into the DHS. Results showed that mean tCOD and sCOD […]

The origin of the German cockroach, Blattella germanica, is enigmatic, in part because it is ubiquitous worldwide in human-built structures but absent from any natural habitats. The first historical records of this species are from ca. 250 ya from central Europe. However, recent research suggests that the center of diversity of the genus is Asian, […]

To anticipate the condition when the peatland emit more carbon, Dr. Devi Nandita Choesin, M. Sc.; Dian Rosleine, S.Si., M.Si., Ph.D.; and their colleagues developed the Generalized Space Time Autoregressive (GSTAR) model in predicting these physical properties for the following weeks. The spatial weight matrix was based on three-dimensional coordinates with a modifcation on the […]

Indonesia, a global biodiversity hotspot, confronts escalating threats from land-use change, triggering extensive forest fragmentation and threatening biodiversity. This review by Dr. Tien Lastini, S. Hut., M.Si. and her colleagues synthesize existing literature on Indonesian forest fragmentation, highlighting key findings, methodologies, and knowledge gaps. Pressures such as agricultural expansion and infrastructure development induce changes in […]

Propolis produced by stingless bees contains various chemical compounds that contribute to its bioactivity. This study by Dr. Muhammad Yusuf Abduh, M.T., and his colleagues was aimed to examine the chemical profile, yield, total flavonoid and phenolic content, and in vitro antioxidant and anti-inflammatory effects of propolis extract from 10 distinct locations in Indonesia.The results […]

Lipopeptide Biosurfactant (LB) is a bacteria derived compound able to reduce surface tension between water and hydrophobic substances and exhibit antimicrobial and anti-biofilm properties. This study by Dr. Eng. Isty Adhitya Purwasena, S.Si., M.Si., aimed to investigate the antimicrobial and anti-biofilm effect of a Lipopeptide Biosurfactant (LB) on Enterococcus faecalis, and its potential use in […]

This study by Jayen Aris Kriswantoro, S.Si., M.Si., and his colleague aims to explore the impact of pretreatment on cacao pod husk (CPH) and investigate the kinetics of biohydrogen production in a dark fermentation (DF) batch reactor with consideration for substrate and inoculum concentration. The study showed that biohydrogen production was significantly increased by 74.4 […]

The process for the synthesis of lectins remains unidentified, it is understood that certain inducing factors can trigger their expression. Prof. Fanny Martha Dwivany, S.Si., M.Si., Ph.D., Dr. Rizkita Rachmi Esyanti, Dr. Sony Suhandono, and their colleagues assessed the gene expression levels of lectins in Cavendish bananas throughout different stages of ripening by contrasting bananas […]

Plant-derived exosome-like nanoparticles (PDENs) are a promising candidate for therapeutic application because they are safe, biodegradable and biocompatible. In this study, papaya PDENs were isolated by a PEG6000-based method and characterized by dynamic light scattering (DLS), transmission Electron Microscopy (TEM), bicinchoninic acid (BCA) assay method, GC-MS analysis, total phenolic content (TPC) analysis, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) […]

Aedes spp. mosquitoes are the primary vectors; however, species such as Culex quinquefasciatus pose significant health risks by transmitting diseases such as filariasis, impacting millions of people worldwide.This study introduces a real-time convolutional neural network-based mosquito classification system using wingbeat frequency for identifying various mosquito species, with emphasis on Aedes sp. Prof. Tjandra Anggraeni, Ph.D., […]
