Prof. Agus Dana Permana and Khalilan Lambangsari, together with the team, explored an innovative solution for managing bovine blood biowaste through bioconversion by Black Soldier Fly (BSF) larvae. By combining food waste and bovine blood as feedstock, they evaluated the larvae’s growth performance, survival rate, waste reduction index, and nutritional content. Remarkably, the treatment with […]

In this study, Marwani E. and team unraveled how geographical origin and climate factors shape the volatile metabolite profiles of Robusta green coffee beans from five major regions in West Java. Through SPME-GC-MS analysis, they identified 143 volatile compounds, with aromatic hydrocarbons, alcohols, and terpenes as the dominant groups. PCA revealed that Bogor beans had […]

Together with Zuhri M., Setiawan N. N., and team, Dr. Susana Paulina Dewi and Prof. Endah Sulistyawati explored seed germination strategies of 31 woody plant species from the submontane tropical forests of West Java, Indonesia. By examining seed traits and conducting germination tests, the study revealed five germination categories: early-high, early-medium, early-low, late-low, and failed. […]

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 […]
