Tourism and marine litter are on a collision course along parts of the Tasikmalaya and Garut Coast (TGC) in West Java. This study offers a practical, place‑based way to manage that tension by combining Sector Analysis (SA), the Coastal Scenic Evaluation System, and the Coastal Clean Index. Seven beaches—from the remote Sancang Nature Reserve to […]
New Research on Devil Rays in the Indian Ocean
A new study published in Marine Biology highlights the urgent conservation needs of two endangered species of devil rays — the Spinetail Devil Ray (Mobula mobular) and the Bentfin Devil Ray (M. thurstoni) — in the Indian Ocean. Researchers found that these rays have extremely low reproductive rates and are highly vulnerable to overfishing. Current […]
Advancing Photonic Crystal Technology for High-Sensitivity Optical Sensors
A team of researchers from Universitas Padjadjaran, Universitas Pakuan, and Universiti Tun Hussein Onn Malaysia has successfully analyzed the double resonance characteristics of photonic crystal structures with defect metal layers. Using the Finite Difference Frequency Domain (FDFD) method, the study revealed that introducing two defect layers—one metal and one sensing material—produces a double resonance effect […]
Unlocking Mangrove Ecotourism Potential in Pangandaran: Insights from Bulaksetra, Bojongsalawe, and Batukaras
A team of researchers from Universitas Padjadjaran and collaborators examined the potential of mangrove ecosystems in Pangandaran, West Java, as a foundation for sustainable ecotourism development. Focusing on three locations—Bulaksetra, Bojongsalawe, and Batukaras—the study combined field surveys, vegetation analysis, water quality assessments, and satellite imagery to measure the mangrove tourism suitability index (TSI). Findings revealed […]
Estuary Water Quality in Cirebon Before and After COVID‑19
COVID‑19 lockdowns offered a rare, real‑world experiment: what happens to estuaries when human activity slows down—and what happens when it resumes? This study tracks water quality in three Cirebon estuaries (Kesenden, Sukalila, Kalijaga) over 2019–2023, comparing pre‑, during‑, and post‑restriction periods. Using the NSF‑Water Quality Index, the team integrated physical (temperature, turbidity, total solids), chemical […]
Probiotics Improve Growth of Snakehead Fish in Bucket System
A new study published in the Egyptian Journal of Aquatic Biology & Fisheries (2025) highlights the effectiveness of probiotics in enhancing the growth and feed efficiency of snakehead fish (Channa striata) cultivated in a bucket system. This innovative aquaculture method addresses land scarcity by using small-scale media, making fish farming more accessible and environmentally friendly. […]
Unlocking the Bioactive Potential of Tropical Brown Macroalgae
A recent study published in Marine Drugs (2025) sheds light on the bioactive compounds and chemodiversity of tropical brown macroalgae, highlighting their potential as a sustainable source for pharmaceuticals, nutraceuticals, and functional food products. Brown macroalgae are rich in unique compounds such as phlorotannins, fucoxanthin, and sulfated polysaccharides, which exhibit antioxidant, anti-inflammatory, and antimicrobial properties […]
Effect of fermented restaurant waste meal addition on growth performance of pangasius catfish (Pangasius pangasius) for promoting sustainable aquaculture
Aquaculture faces two pressing challenges: the high cost of feed and the environmental burden of waste. This study by researchers from Universitas Padjadjaran investigates how fermented restaurant waste flour (FRWF) can be used as a low-cost, eco-friendly feed ingredient to improve the growth of pangasius catfish fry (Pangasius pangasius). Restaurant waste typically contains useful nutrients—protein, […]
Nanoplastics in aquatic environments: The hidden impact of aging on fate and toxicity
Nanoplastics—tiny plastic particles smaller than 1 µm—are increasingly recognized as an invisible but serious threat to aquatic ecosystems. While much research has focused on their presence and immediate toxicity, this study emphasizes a critical but underexplored dimension: how nanoplastics “age” once they enter the environment, and how this aging alters their behavior, interactions, and risks. […]
Eco‑Friendly Biocomposites that Clean Dyes from Wastewater
Industrial dye effluents are a persistent source of water pollution in many developing regions. This study presents a greener pathway to remove dyes—specifically methylene blue—by engineering a hybrid biocomposite made from alginate, polycaprolactone (PCL), and TiO₂. The materials were compounded and characterized using XRD, FT‑IR, tensile testing, DSC/TGA, and biodegradation assays, then evaluated for their […]
New Marine-Derived Compounds Show Promise Against Breast Cancer
A research team led by Universitas Padjadjaran, in collaboration with Bandung Institute of Technology, IPB University, Universitas Andalas, and Universiti Malaysia Terengganu, has successfully identified two novel compounds—Unguisol A and Unguisol B—from the marine fungal symbiont Aspergillus unguis, isolated from sponges in the Seribu Islands, Indonesia. Published in the Journal of Experimental Pharmacology (2025), this […]
Effects of Dietary Tryptophan Supplementation on Melatonin and Oocyte Maturation in African Catfish, Clarias gariepinus
African catfish (Clarias gariepinus) is one of the most important freshwater aquaculture species due to its adaptability, fast growth, and commercial value. However, its reproduction is naturally seasonal, creating challenges for year-round seed production. This study explored how dietary supplementation of tryptophan, an essential amino acid, could influence reproductive hormones and oocyte maturation in African […]
