Abstract

Traditional fish smoking methods often raise significant concerns regarding product safety, quality inconsistency, and environmental pollution. This study aimed to evaluate a modified Efhilink smoking cabinet designed to address these issues by utilizing agricultural waste, specifically corn cobs and coconut shells, as bio-smoke sources for producing high-quality, safe smoked fish compliant with the Indonesian National Standard (SNI 2725:2013). Three fish species (mackerel tuna, Euthynnus affinis; flying fish, Cypselurus spp.; and ray, Dasyatis spp.) were processed using the modified cabinet and a traditional cabinet (control) and subsequently analyzed for sensory properties, proximate composition, histamine, TVB-N, pH, total phenolic content, and various contaminants (microbiological, heavy metals, chemical residues, and polycyclic aromatic hydrocarbons (PAH4)). The results demonstrated that all smoked fish samples from the modified cabinet met all critical parameters of the national standard. Coconut shell smoke generally yielded superior products, characterized by higher acceptability in aroma and taste, a greater infusion of phenolic compounds (up to 0.334 mg/kg), and significantly lower levels of PAH4 contaminants compared to the traditional control. All samples from the modified cabinet exhibited histamine levels well below the 100 mg/kg safety limit (12.36–19.37 mg/kg), total plate counts within the permissible range (10 to 3.6x10? CFU/g), and a complete absence of detectable pathogens (E. coli, Salmonella spp., S. aureus, V. cholerae) or hazardous chemical residues (chloramphenicol, malachite green, nitrofuran); heavy metal contaminants were also found at levels far below the maximum allowable limits. The modified cabinet significantly outperformed the traditional method in reducing PAH4 contamination. The technology not only enhances food safety but also promotes sustainable practices by converting agricultural waste into value-added products. In conclusion, the modified Efhilink cabinet, using either corn cob or coconut shell bio-smoke, effectively produces safe, high-quality smoked fish that complies with stringent food safety standards, with coconut shells demonstrating superior performance as a smoke source by enhancing sensory attributes and bioactive compound content while minimizing hazardous contaminants.

Abstract

The Green Belt area is a buffer area in an industrial area that functions as a barrier or separates the mining area from other regions, such as residential areas or community agriculture. The Green belt area consists of various plant vegetation that absorbs carbon dioxide and air conditioning, preventing sedimentation and erosion in the mining area. Arbuscular mycorrhiza has the potential to live in the green belt area by forming a mutualism symbiosis with plants or vegetation in the area. This study aimed to determine arbuscular mycorrhizae found in the Greenbelt area of PT Semen Indonesia Tbk Tuban. Sampling used purposive sampling techniques at three sampling stations, namely rhizosphere eucalyptus (Malaleuca cajuputi), trembesi (Samanea saman), and sawo (Manilkara zapota). The study was conducted in November 2021 through three stages: sampling, sample isolation, and species identification. The results showed seven types of arbuscular mycorrhiza from five different genera, namely the genus Glomus, Acaulospora, Gigaspora, Racocetra, and Archaeospora. The most found species is the genus Glomus. This research contributes as a source of literacy and information about the types of AMF found in PT Semen Indonesia's Greenbelt area, which can be used as biological fertilizer, support plant growth, help reclaim mining areas, and protect plants from drought pressure in mining areas.
