Abstract

Blood glucose, a form of sugar present in the bloodstream, is derived from dietary carbohydrates and stored as glycogen in the liver and skeletal muscles. Blood glucose levels of 140 mg/dL in random testing or 120 mg/dL in fasting tests the indication of diabetes mellitus (DM). According to the World Health Organization (WHO) in 2021, DM is among the top ten leading causes of death globally. Blood glucose levels can be measured using various methods, including chemistry analyzers, glucometers, and spectrophotometers. This study aims to evaluate the differences in blood glucose levels obtained using these three analytical methods. The study aims to compare blood glucose levels measured using a chemistry analyzer, glucometer, and spectrophotometer. A descriptive research method was applied, with samples collected through random sampling, comprising 25 normal and 25 elevated blood glucose level samples. The majority of participants were women (76.0 %, n=38), while men represented 24.0 % (n=12), with an average participant age of 57.8 years. In the normal group, blood glucose levels measured using the chemistry analyzer ranged from 72 mg/dL to 116 mg/dL, with a mean of 90.52 mg/dL. Measurements using the glucometer showed a range of 75 mg/dL to 129 mg/dL, with a mean of 95.88 mg/dL, while the spectrophotometer results ranged from 74 mg/dL to 120 mg/dL, with a mean of 93.00 mg/dL. In the high blood glucose group, measurements using the chemistry analyzer ranged from 195 mg/dL to 342 mg/dL, with a mean value of 272.04 mg/dL. Measurements with the glucometer ranged from 200 mg/dL to 358 mg/dL, with a mean value of 278.44 mg/dL, while the spectrophotometer results ranged from 199 mg/dL to 354 mg/dL, with a mean value of 275.48 mg/dL. Based on the results, the chemistry analyzer demonstrated higher precision and accuracy in measuring blood glucose levels compared to the glucometer and spectrophotometer.

Abstract

This study aims to determine the manufacture of adsorbents made from activated carbon areca nut shell coated with nanochitosan from shrimp shells. The carbon from the areca nut shell was obtained by heating process using a temperature of 300oC. The carbon obtained is activated with H2SO4 and then modified by coating activated carbon with nanochitosan. Chitosan was prepare through isolation the stages of deproteinization, demineralization, and deacetylation. Chitosan will be characterized using FTIR. The change in size of chitosan to nano chitosan was evaluated by ionic gelation method with 1% NaTPP. The nanochitosan obtained will be characterized using PSA. The results of FTIR characterization showed the presence of an N-H group at a wave number of 3345.89 cm-1. PSA characterization gave a result that the particle size of shrimp shell chitosan was nano-sized, which was 51.11 nm.

Abstract

Schiff bases were successfully synthesized via a condensation reaction between dialdehyde starch (DAS), derived from breadfruit (Artocarpus altilis) starch, and aniline. DAS was prepared through oxidative cleavage of the vicinal diol groups in native starch using sodium periodate. The formation of DAS was confirmed qualitatively by the appearance of a brick-red precipitate upon addition of Fehlings reagent and a marked increase in its water solubility. Fourier Transform Infrared (FT-IR) spectroscopy revealed a strong absorption band at 1635.64 cm, corresponding to the aldehyde C=O stretching vibration, supporting the successful oxidation. The oxidized starch showed a high degree of oxidation (80.9%) and a carbonyl content of 10.36%. Condensation between the aldehyde groups of DAS and the amino group of aniline resulted in the formation of a Schiff base. FT-IR analysis of the resulting compound revealed absorption bands at 1635.64 cm and 1604.77 cm, indicating the formation of imine (-C=N-) bonds, while a peak at 871.82 cm confirmed the presence of aromatic ring structures. The antibacterial activity of the synthesized Schiff base was evaluated using the disk diffusion method, showing strong inhibitory effects against Escherichia coli and Staphylococcus aureus. These findings showed that starch-based Schiff bases represent a promising class of biodegradable antibacterial agents with potential applications in biomedicine and biomaterials.

Abstract

Arsenic contamination in water is a critical environmental concern due to its high toxicity and persistence, posing serious risks to human health and ecosystems. Adsorption is considered one of the most efficient and cost-effective methods for arsenic removal, especially using composite adsorbents. This study evaluates several silica-based composite adsorbents designed to enhance arsenic removal from aqueous solutions. The composites combine silica with various functional materials, including iron oxide, iron(III) nitrate, iron(III) chloride, manganese, magnesium, activated carbon, and polyamines, aiming to improve adsorption capacity, selectivity, thermal stability, and reusability. Adsorption performance was assessed under varying pH levels, adsorbent dosages, contact times, initial arsenic concentrations, and temperatures. Among the tested materials, the iron oxide loaded silica (IOLS) composite (silica, iron(II) sulfate, and iron(III) chloride) exhibited the highest As(III) adsorption capacity of 82.4 mg/g at pH 7 with 90 minutes contact time. Meanwhile, the ironmanganese oxide incorporated rice husk silica (FMRS-2) composite (silica, iron oxide, and manganese) achieved an As(V) adsorption capacity of 20.3 mg/g at pH 7 after 24 hours, with 100% removal efficiency sustained over four regeneration cycles.
