Abstract

Free-living N2-fixing bacteria are essential in the soil because they provide a source of nitrogen in the form of ammonium needed by plants to be used in building protein blocks. The fixation of free N2 needs to be increased by adding nanomaterials such as magnetite (Fe3O4), which has an active group and can be a source of nitrogenase enzyme cofactor. In this study, increased N2 fixation used N2-fixing bacteria in Burks medium. This increase was determined by measuring NH3 levels using the Phenate method formed after Burks medium was treated with Fe3O4 and chitosan-magnetite (CS-Fe3O4). The study found that the number of bacteria can be well decreased. This research showed that using Fe3O4 and CS-Fe3O4 increased NH3-N levels in cultures of free-living nitrogen-fixing bacteria by 15.40% and 75.54%. For future development, it can be in the form of optimization, the effect of adding the same material to plant secondary metabolites, and the mechanism of bacteria in using the material.

Abstract

A common enzyme for superoxide anion radicals biosensors is superoxide dismutase (SOD). Deinococcus radiodurans protein extract can replace the use of pure SOD enzymes for superoxide anion radicals biosensors. The purpose of this research is to determine the analytical performance of the superoxide anion radicals biosensor with protein extract of Deinococcus radiodurans immobilized on carboxymethylcellulose-gelatin-zeolit (CMC-G-Z) that is crosslinked by glutaraldehyde. The response surface method showed that the optimum condition for the biosensor was pH 7, protein extract concentration of 1075 µg/ml, zeolite concentration of 5 mg/ml, and glutaraldehyde concentration of 0.0042 M. Stability of the biosensor retained 67% of its sensitivity after use for 24 hours. The biosensor exhibits good analytical performance with a linear range from 0.1 – 0.8 mM, a detection limit of 77.84 µM, and a limit of quantification of 259.5 µM with a correlation coefficient of 0.9905.

Abstract

The quality of crude palm oil (CPO) is influenced by the quality of fresh fruit bunches, crop culture, and postharvest handling. A delay in fruit processing can cause physical damages to the fresh fruit bunches. Gibberellic acid (GA3) can potentially reduce the physical damage due to delayed processing of the fresh fruit bunches. Our study aims to determine how GA3 affects the physical and chemical quality of oil palm fresh fruit bunches. The fresh fruit bunch samples were collected from the IPB-Cargill Palm Oil Education and Research, Jonggol, Bogor, Indonesia. This study used a randomized complete block design that consisted of four concentrations of GA3: 0, 12.5, 25 and 37.5 ppm. GA3 application reduced fruit loss, respiration rate, and maintain fruit moisture and firmness, increased the oil content, and stabilize the free fatty acid content. GA3 concentration of 12.5 ppm is the optimal concentration. Based on the correlation analysis, fruit softness has a strong correlation with free fatty acids.

Abstract

Lead (Pb) contamination in water poses serious environmental and health risks, necessitating the development of effective and sustainable adsorbents for its removal. This study aimed to synthesize and characterize magMCM-41 composites derived from rice husk silica, and evaluate their performance for Pb(II) ion removal in aqueous solutions. The magMCM-41 was prepared by integrating magnetite (Fe3O4) nanoparticles into a mesoporous silica framework via co-preparation and sol-gel methods using cetyltrimethylammonium bromide (CTAB) as a template. Characterization by XRD, FTIR, BET, and PSA confirmed successful composite formation, revealing a high specific surface area o f 476.744 m2/g, a mesoporous framework (pore diameter 3.83 nm), and an average particle size of 362.7 nm. Adsorption conditions were optimized using Response Surface Methodology (RSM); pH positively influenced capacity, whereas adsorbent dosage had a negative effect. The maximum adsorption capacity was 115.77 mg/g at pH 5 with 0.05 g of adsorbent. The Dubinin-Radushkevich model best described the adsorption equilibrium (R2=0.935), indicating physisorption on a heterogeneous surface. Thermodynamic analysis confirmed a spontaneous and exothermic process. These results demonstrate that rice husk-derived magMCM-41 is a sustainable and magnetically separable adsorbent with high potential for Pb(II) remediation.

Abstract

Myristicin is the key marker of nutmeg (Myristica fragrans) quality, while methyl eugenol is an undesirable compound requiring strict monitoring. This study aimed to optimize the extraction conditions of these compounds from nutmeg seeds and mace as a pretreatment step prior to electrochemical quantification. Optimization was performed using Response Surface Methodology (RSM) with a Box–Behnken Design (BBD), considering extraction time (h), ethanol concentration (%), and the sample-to-solvent ratio (g/mL) as independent variables. The analytes were quantified by Gas Chromatography–Mass Spectrometry (GC-MS), and the experimental data were modeled using Design Expert software. Regression models indicated that ethanol concentration and solvent volume significantly influenced extraction yields, while extraction time had a statistically minimal effect (p-values > 0.05, small effect sizes). Nevertheless, practical differences were observed between matrices: nutmeg seeds reached optimal extraction within 2 hours, whereas mace required 17 hours, likely due to its higher essential oil content and fibrous structure, which slows diffusion kinetics. Thus, although time effects were not statistically significant, extended extraction was practically preferred for mace to ensure adequate recovery. Response definitions were specified as follows: Y1 = myristicin concentration (mg/mL), Y2 = methyl eugenol concentration (mg/mL), and % extraction yield. The optimal extraction conditions were achieved with 90% ethanol and 50 mL solvent, maximizing analyte detectability while maintaining reproducibility across seed and mace extracts. These optimized ethanolic matrices are compatible with subsequent electrochemical quantification, given their aqueous/ethanolic composition and anticipated sensitivity of electrochemical detection.
