Abstract

This research focused on the evaluation of raw broiler chicken meat texture and pathogenic antibacterial effect under the treatment of grade 2 coconut-shell liquid smoke (CSLS) as a food preservative. Compound identification of grade 2 CSLS was conducted using the GC-MS method. The main chemical compounds of CSLS were polyunsaturated fatty acid derivates, fatty acid and phenol. The evaluation of texture was conducted on raw broiler chicken meat under the treatment of grade 2 CSLS during storage at 25 ℃ for 7 days. The effect of antibacterial activity of grade 2 CSLS with different concentration (i.e., 5%, 25%, 50%, and 75%) were tested using Gram-positive bacteria on several pathogenic bacteria such as L. monocytogenes, S. aureus, P. Aeruginosa, and E. coli. The results indicated that grade 2 CSLS influenced the inhibited zone of L. monocytogenes, S. aureus, P. Aeruginosa, and E. coli respectively with linear correlation. The optimal concentration of grade 2 CSLS resulted in a concentration of 50%, which was the most optimal against L. monocytogenes, S. aureus, P. Aeruginosa, and E. coli as pathogenic bacteria strains.

Abstract

Conventional organic waste management methods often lead to environmental degradation and underutilization of valuable resources. In rural areas, such as Polaman Village, limited awareness and inefficient disposal systems exacerbate these issues, thus necessitating innovative and sustainable solutions. This study explores black soldier fly larvae (BSFL) bioconversion as a community-based solution for organic waste management, addresses environmental challenges, and promotes economic empowerment by converting waste into valuable by-products. The study employed a mixed-methods approach, beginning with baseline assessments of waste generation and existing management practices to identify community needs. Educational workshops and hands-on training sessions introduced BSFL bioconversion techniques to local stakeholders. Focus group discussions (FGDs) were conducted to facilitate dialog and collaboration between Polaman residents, the Polaman Resik Sejahtera Waste Bank, and Universitas Diponegoro. Continuous mentoring and pilot trials were conducted to ensure proper adoption and to demonstrate the feasibility of the proposed system. The results reveal that BSFL bioconversion significantly reduces organic waste while producing valuable by-products such as compost and larvae. These findings demonstrate the potential of BSFL bioconversion to align with circular economy principles, contributing to environmental sustainability and economic resilience. The project serves as a scalable model for addressing organic waste challenges in rural communities while advancing the green economy agenda.

Abstract

The browning of freshly sliced apples greatly diminishes their quality and attractiveness to consumers. Edible coatings offer a viable solution for maintaining the quality and prolonging the shelf life of cut fruit. This research examined the impact of combining maltodextrin and chitosan in edible coatings on the quality of fresh-cut apples. The dip-coating technique was utilized to apply the coating. A Completely Randomized Design (CRD) with two factors was used, featuring various maltodextrin (MD)-to-chitosan weight ratios (1:1, 1:3, and 3:1) and two types of maltodextrin with different dextrose equivalent (DE) values (10 and 25). The performance of the edible coatings was assessed over a 10-day storage period at 4°C, with evaluations conducted on days 0, 2, 4, 6, 8, and 10. The findings indicated that the optimal preservation of apple quality was achieved with a 3:1 MD-to-chitosan ratio combined with DE 25, resulting in a browning index of 36.09, firmness measuring 5.7 kg/cm², vitamin C content of 20.43 mg/100 g, and a weight loss of 18.09%. In terms of organoleptic assessment (rated on a 1–5 scale), samples with the same MD-to-chitosan ratio received the highest ratings for color (2.65) and texture (2.5). The treatment with a 3:1 MD-to-chitosan ratio and DE 10 yielded the best aroma score of 2.3.
