Abstract

Slag waste from the metal refining industry, if left to accumulate for a long time, can become a source of environmental pollution due to the content of heavy metals that can dissolve and spread to the surrounding environment. However, slag can also be an alternative source for obtaining valuable metals. Aim: This study aims to examine the ability of diethylaminedithiocarbamate ligands to recover nickel metal from slag waste through the mechanism of complex compound formation. Methodology and results: The extraction process was carried out at the optimal pH for each ligand to maximize the selectivity and efficiency of metal recovery. Characterization of the complex compounds from the reaction was carried out using various analytical techniques, including Fourier Transform Infrared Spectroscopy (FTIR), UV-visible spectroscopy (UV-Vis), X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS), and melting point tests to determine the thermal stability of the compound. The study results indicate that diethylaminedithiocarbamate ligands can selectively form complex compounds with nickel metal in slag and are effective in recovering metals from slag waste with a recovery value of 94.88%. Conclusion, significance, and impact study: The results of this study indicate that using diethylaminedithiocarbamate ligands can be an environmentally friendly approach to using slag waste as a secondary source of metals.

Abstract

Ulva sp. is a type of seaweed that has high potential as a sea vegetable with sufficient protein and economic value. This study aims to determine the effect of washing and storage methods on the quality of Ulva sp. powder in CV. Lars. The research was conducted using two washing methods (seawater and fresh water), two types of packaging (black plastic and aluminum foil), and storage time of 0, 15, and 30 days at room temperature. The parameters analyzed included moisture content, impurity content, color (CIELab model), and organoleptic test. The results show that washing with fresh water packaged in aluminum foil gives the best results in keeping moisture content low, maintaining its natural green color, and providing an acceptable taste and aroma. The average impurity level is below 1%, indicating that both washing methods are equally effective. The discoloration towards yellow occurs more often in washing using seawater. In conclusion, the combination of washing with fresh water and storage using aluminum foil packaging is the best treatment in maintaining the quality of Ulva sp powder. during storage

Abstract

This study evaluated the effect of bromelain enzyme supplementation on the sensory quality of anchovy (Stolephorus sp.) fish sauce. The experiment was conducted from August to September 2025 using a Completely Randomized Design (CRD) with two treatments: a control without bromelain and a treatment supplemented with 30 g bromelain enzyme. Fresh anchovies were fermented under controlled laboratory conditions using identical salt and water compositions. The resulting fish sauce was evaluated through a hedonic sensory test assessing taste, aroma, texture, and appearance, while amino acid analysis was prepared using High-Performance Liquid Chromatography (HPLC). The sensory evaluation showed that bromelain supplementation slightly reduced panelists' preference for taste (2.9 to 2.7) and aroma (2.8 to 2.7), indicating that enzymatic hydrolysis generated peptides and volatile compounds that moderately altered sensory perception. Conversely, bromelain improved texture, increasing the hedonic score from 3.1 to 3.3, suggesting that protein hydrolysis produced a smoother and more acceptable consistency. Appearance remained unchanged, with both treatments obtaining an average score of 3.7, indicating that bromelain did not affect the visual characteristics of the product. Overall, bromelain enzyme accelerated protein modification while maintaining acceptable sensory quality. These findings suggest that controlled bromelain supplementation has considerable potential as an enzymatic strategy to improve fish sauce processing efficiency while preserving consumer acceptance and supporting the development of higher-quality fermented fish products.

Abstract

Kecap ikan teri merupakan produk fermentasi yang kaya protein sehingga berpotensi menghasilkan kandungan asam amino yang tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan enzim papain terhadap total asam amino serta mutu organoleptik kecap ikan teri dan membandingkannya dengan kecap tanpa enzim. Metode penelitian menggunakan dua perlakuan, yaitu A (0g enzim papain) sebagai kontrol dan B (10g enzim papain). Analisis komposisi asam amino dilakukan menggunakan kromatografi cair kinerja tinggi (HPLC), sedangkan evaluasi organoleptik dilakukan melalui uji hedonik. Data diolah dengan uji non-parametrik menggunakan Mann-Whitney U. Hasil analisis menunjukkan bahwa total asam amino sampel A adalah 19.49% w/w, sedangkan sampel B adalah 11.54% w/w, yang menunjukkan rendahnya kadar asam amino akibat penambahan enzim papain. Hasil uji organoleptik menunjukkan bahwa penambahan enzim papain menurunkan nilai rasa pada sampel B 2.6 (cukup suka) dan nilai warna pada sampel B 3.1 (cukup suka), sedangkan sampel tanpa penambahan enzim papain meningkatkan nilai rasa pada sampel A 2.7 (cukup suka) dan nilai warna pada sampel A 3.3 (cukup suka), sedangkan sampel tanpa penambahan enzim papain menunjukkan penurunan nilai bau pada sampel A 2.5 (kurang suka) dan nilai tekstur pada sampel A 2.8 (cukup suka), sedangkan pada sampel dengan penambahan enzim papain menunjukkan peningkatan nilai bau pada sampel B 2.6 (cukup suka) dan nilai tekstur pada sampel B 3.0 (cukup suka). Hasil uji Mann-Whitney U menunjukkan bahwa penambahan enzim papain berpengaruh negatif terhadap asam amino dan nilai organoleptic rasa dan warna kecap ikan teri.

Abstract

The increasing accumulation of non-biodegradable plastic waste has encouraged the development of environmentally friendly alternatives derived from renewable natural resources. One promising material is cellulose extracted from the red seaweed Kappaphycus alvarezii, which possesses favorable characteristics for bioplastic production. This study aimed to evaluate the degradability of azo dyes and microbial activity in bioplastics produced from K. alvarezii cellulose with different cellulose-to-cassava starch ratios. The research was conducted from July to October 2025 using five formulations: F1 (5:5), F2 (8:2), F3 (2:8), F4 (0:10), and F5 (10:0). Cellulose extraction was performed through alkaline and acid hydrolysis methods, while bioplastic films were produced through solution casting with glycerol as a plasticizer. Azo dye degradation was analyzed using UV–Visible spectrophotometry, whereas microbial activity was evaluated through Total Plate Count (TPC) analysis. The UV–Vis results revealed no characteristic absorption peaks of azo dyes in the 300–500 nm wavelength range, indicating the absence or successful degradation of azo chromophores in all formulations. Cellulose-rich formulations exhibited higher optical transparency and greater film homogeneity than starch-dominated formulations. TPC values ranged from 0 to 420 CFU g⁻¹ and remained substantially below the maximum limit established by SNI 7388:2009 (4,400 CFU g⁻¹), confirming excellent microbiological quality and product safety. Statistical analysis using the Kruskal–Wallis test showed no significant differences among formulations (p > 0.05). The combined findings demonstrate that cellulose-based bioplastics derived from Kappaphycus alvarezii possess good biodegradation potential, are free from detectable azo dye contamination, and maintain low microbial contamination levels. Therefore, these bioplastics have strong potential as sustainable alternatives to conventional petroleum-based plastics for food packaging, cosmetic packaging, and other environmentally sensitive applications
