Abstract

The growing demand for environmentally friendly and halal-compliant gelatin in Indonesia necessitates the exploration of alternative sources based on organic waste. One such potential lies in the underutilized waste of the catfish (Clarias gariepinus) head skin. This study aims to synthesize and characterize halal gelatin derived from catfish head skin using asam kandis (Garcinia cowa) as a natural acid solvent through an acid-based extraction method. The extraction process consisted of three main stages: degreasing, demineralization, and extraction at 55°C. An experimental approach was employed to assess the physicochemical parameters of the extracted gelatin. The analysis revealed moisture content of 10.01%, ash content of 0.24%, fat content of 1.07%, pH of 5.60, gelling point of 13°C, melting point of 29°C, and viscosity of 6.0 cP, all of which comply with the Indonesian National Standard (SNI 06-3735-1995) for gelatin quality. FTIR characterization showed distinctive absorption spectra for Amide A (3276–2939 cm⁻¹), Amide I (1630 cm⁻¹), Amide II (1532–1447 cm⁻¹), and Amide III (1241 cm⁻¹), confirming successful collagen conversion into gelatin. In conclusion, catfish head skin presents promising potential as a halal, eco-friendly gelatin source that meets national quality standards.

Abstract

This study aims to determine the concentrations of heavy metals—iron (Fe), manganese (Mn), and lead (Pb) in drinking water samples using the Atomic Absorption Spectrophotometry (AAS) method. The research employed a descriptive quantitative approach, involving the preparation of standard solutions and the analysis of filtered drinking water samples. Measurement results indicated that the concentrations of Fe (–0.3714 mg/L), Mn (–0.1098 mg/L), and Pb (–0.5218 mg/L) were below the instrument’s detection limit, resulting in negative values. These findings suggest that the levels of heavy metals in the samples are extremely low and well below the maximum limits set by the Regulation of the Minister of Health of the Republic of Indonesia No. 2 of 2023: 0.3 mg/L for Fe, 0.1 mg/L for Mn, and 0.01 mg/L for Pb. The study concludes that the tested drinking water samples meet quality standards and are safe for consumption, posing no health risks from heavy metal exposure. Additionally, AAS proved to be an effective method for detecting trace metal concentrations, making it suitable for regular and sustainable water quality monitoring.
