Abstract

The content of tetracycline residues in poultry meat products can cause antibiotic resistance in humans who consume these products, so it is necessary to develop sensitive analytical techniques to determine the levels of tetracycline residues to assess the safety of these products for consumption. The molecular imprinting technique is a method to produce sorbents with molecular recognition capability of target compounds that can be used to increase the selectivity of solid phase extraction to extract tetracycline residues for further analysis. This study aimed to obtain a sorbent synthesized by molecular imprinting technique to analyze tetracycline in poultry meat products. The stages of the research began with the study of the interaction of functional monomers with template molecules, determining the association constants of functional monomers with template molecules, synthesis of imprinted polymer molecules using bulk and precipitation methods, evaluating the ability and adsorption capacity of the synthesized polymers, assess the selectivity of polymers for analog structures and physical characteristics with FTIR. The research showed that methacrylic acid was the best functional monomer with a binding energy value of -27.3776 kcal/mol. The higher adsorption capacity was achieved by Molecularly Imprinted Polymer (MIP) that was synthesized by precipitation method (MIP2) than the other MIP synthesized by bulk polymerization (MIP1) with a value of 0.8748 mg/g and 0.4077 mg/g, respectively. The analogous compounds' imprinting factor values for each MIP were 1.197 and 1.1272. The polymer synthesized by molecular imprinting technique is selective for extracting and analyzing tetracycline from poultry meat matrix.

Abstract

Tetracycline (TC) residues in poultry meat products can create antibiotic resistance in humans who consume them. Hence, sensitive analytical procedures to evaluate the quantities of tetracycline residues are required to assess the safety of these products for consumption. The study aimed to develop a sorbent using molecular imprinting technology to analyze tetracycline in chicken broiler meat products. The study used several tests and computational techniques to increase the effectiveness of screening for the best MIP systems. According to the bond energybased computational analysis, methacrylate acid (MAA) was the best functional monomer at a TC-to-MAA molar ratio of 1:6. The mixture of methanol and chloroform yielded the greatest Ka. The Job plot showed that a TC-to-MAA-molar ratio of 1:6 was best for synthesizing imprinted polymer in the mixture of methanol and chloroform. We generated MIPs using two alternative production methods: bulk (MIP1) and precipitation (MIP2). Adsorption capacity results revealed that MIP1 matches well with the Langmuir model, whereas MIP2 fits better with the Freundlich. MIP1 application produced recovery rates of 82,74±4.1% and MIP2 results of 92.14±3.2% for TC in spike-chicken meat. The outcomes of the selectivity test also demonstrated that MIP2 is superior to MIP1 and can recover TC from spiked chicken meat while coexisting with another antibiotic drug. The study’s findings indicate that MIP2 helps determine TC in spike chicken meat.

Abstract

Hypertension is a non-communicable disease often referred to as a "silent killer" because it may develop without noticeable symptoms and can lead to serious complications if left untreated. Elderly individuals are among the high-risk groups who require special attention in efforts to prevent and control hypertension. This community service activity aimed to improve the knowledge of elderly residents regarding hypertension through health education as a preventive measure against further complications. The program was conducted in Parakan Village, Garut Regency, involving 30 elderly participants. The method used was health education combined with pre-test and post-test assessments to evaluate knowledge improvement. The results showed a significant increase in understanding after the session, particularly regarding the symptoms and prevention of hypertension. Another notable finding was that most participants had only elementary-level education, which influenced their receptiveness to health information. In conclusion, health education proved effective in enhancing the elderly's knowledge of hypertension and its potential complications. Periodic follow-up education and collaboration with local health services are recommended to sustain the impact.
