Abstract In this study, the organic polymer monolith was developed as a weak anion exchanger column in high performance liquid chromatography for DNA separation. Methacrylate-based monolithic column was prepared in microbore silicosteel column (100 x 0.5 mm i.d.) by in-situ polymerization reaction using glycidyl methacrylate as monomer; ethylene di...

Scopoletin is regarded as a major constituent of noni (Morinda citrifolia L), which contributes to the antioxidative, anti-inflammatory, immunomodulatory, and hepatoprotective properties in noni. It is also suggested as a marker for identification and quality control of noni and its derivative products. With the increasing interest in noni due to i...

Scopoletin, also known as 6-methoxy-7 hydroxycoumarin, is one of the naturally occurring coumarin commonly found in many edible plants and plays an important role in human health. Despite the various potential pharmacological properties, the biosynthesis process, method of extraction, and mechanism of action on this compound have not been documente...

Response surface methodology is employed to investigate the optimum evaporative light scattering detector (ELSD) operating conditions for high performance liquid chromatography (HPLC) analysis of frondoside A, which is a bioactive compound valuable for its anti‐cancer activity. The results suggest that ELSD response is mostly affected by nebulizing...

Foodborne pathogens may cause foodborne illness, which is among the major health problems worldwide. Since the therapeutic options for the treatment of the disease are becoming limited as a result of antibacterial resistance, there is an increasing interest to search for new alternatives of antibacterial. Bioactive essential oils from Curcuma sp be...

Pseudomonas aeruginosa can regulate its pathogenicity via quorum sensing (QS) system. Zingiber cassumunar and Z. officinale have been used for the treatment of infectious diseases. The study aimed to evaluate and compare the chemical constituents, antibacterial, and QS inhibitor of Z. cassumunar essential oils (ZCEO) and Z. officinale essential oil...

Cancer is considered a leading cause of death worldwide due to its high morbidity and mortality rate. Conventional treatments for cancer therapy, such as chemotherapy, and radiotherapy, have been hampered by their side effects. Natural product-derived plants have been used for decades to treat diseases. Compared to conventional therapy, natural pro...

A sensitive liquid chromatography method was developed for the determination of β-carotene in high β-carotene modified cassava flour (MOCAF). β-carotene was separated isocratically on a reversed-phase high performance liquid chromatography (HPLC) system, employing a C18 column stationary phase and a methanol-acetonitrile elution system with the rat...

The antibiotic resistance has dramatically increased, particularly against the Gram-negative bacteria and caused critical health problems. One appealing strategy to overcome this problem is the use of combinations of natural products and commercial antibiotics. Pseudomonas aeruginosa is a Gram-negative pathogen that is difficult to control. Essenti...

Improving access to safe drinking water in developing countries is still a challenge and Gravity-Driven Membrane (GDM) filtration systems may be a sustainable solution. Two rural schools in West Java Indonesia were studied, one as a control site and another having an installed GDM system. Chemical and microbiological water quality data were collect...

Antibacterial resistance has become a major global public health issue. Pathogens such as Staphylococcus aureus, Bacillus subtillis, Escherichia coli, and Klebsiella pneumoniae associated with most community infections are linked with antibiotic resistance. Curcuma xanthorrhiza is a traditional medicine used to prevent and cure bacterial infection....

Carboxymethyl glucomannan (CMGM) was successfully synthesized through the reaction of glucomannan from Amorphophallus oncophyllus and monochloroacetic acid, using NaOH as a catalyst. Two types of glucomannan were used in this study, low viscosity glucomannan (LGM) and high viscosity glucomannan (HGM). The produced CMGM were differentiated into LCMG...

Indonesia is the second-largest contributor of microplastics (MPs) pollution in the marine ecosystem. Most MPs pollution-related studies in Indonesia focus on seawater, sediment, with less information found on the commercially important fish species used for human consumption. Skipjack Tuna (Euthynnus affinis) is one of the major exporting fishery...

The transportation sector primarily causes urban air pollution in Indonesia and has a significant role in environmental emissions. Emissions resulting from vehicles are particulate matter, SO 2 , CO 2 , CO, HC, and NO x . The concentration and dispersion of PM 10 and SO 2 from the activity of the traffic on the roads Kuin Utara and Kuin Selatan, Ba...

Dalam penelitian ini, monolith polimer organik berbasis polistirena dikembangkan sebagai kolom kromatografi fasa terbalik pada kromatografi cair kinerja tinggi (KCKT) untuk pemisahan senyawa-senyawa dengan ukuran molekul kecil, yaitu alkilbenzena. Kolom monolith dibuat dalam kolom silicosteel berukuran microbore (100 ´ 1,02 mm i.d) secara polimeris...

A polymer monolithic column, poly-(methacrylatoethyltrimethylammonium chloride-co-vinylbenzyl chloride-co-ethylene dimethacrylate) or poly-(MATE-co-VBC-co-EDMA) was successfully prepared in the current study by one-step thermally initiated in situ polymerization, confined in a steel tubing of 0.5 mm i.d. and 1/16" o.d. The monoliths were prepared f...
