Abstract

The purpose of the study was to analyze hydrolysate astaxanthin as an inhibitor of the enzyme alf glucosidase. The method used is an experimental method by applying a Complete Random Design (RAL) The treatment used is a concentration of different papain enzymes, consisting of 3 treatment levels namely t1 (3%), t2 (6%), and t3 (9%). Observations made are 1) proximal analysis; 2) analysis of hydrolysate astaxanthin and its antioxidant activity; 3) analysis of the inhibition test of the enzyme alpha glucosidase and its inhibitory mechanism. The results showed that the proxmat of vanname shrimp skin flour is; water content (9.20% bb), ash (31.46% bk), fat (1.64% bk), protein (37.60% bk), and carbohydrates (29.29% bk) (by different) with a yield of 36.22%. The highest astaxanthin content at the 3% papain enzyme concentration of 3.57 μg/g with the best antioxidant activity has the smallest IC50 value of 88,793 ppm and astaxanthin shows inhibition activity of alpha glucoside enzyme by 49.38% - 58.87% and astaxanthin has a competitive enzyme inhibition mechanism resulting in a decrease in postrandial blood glucose levels.

Abstract

Bukit Batu River in Bengkalis Regency plays a vital role as a water source for domestic use, irrigation, industry, and transportation. However, increasing domestic and industrial activities have significantly contributed to water pollution. This study aims to analyze the current water quality and socio-economic activities, assess water quality status and pollution load, and formulate pollution control strategies. The research employed field observations, laboratory testing of physical, chemical, and biological water parameters, and SWOT analysis. Results show that parameters such as COD and ammonia exceeded Class II quality standards, indicating a moderately polluted condition. The primary pollution sources include domestic waste, agriculture, and industry. Pollution control strategies were developed based on strengths and opportunities, such as community awareness and active involvement of local government. The study concludes that multi-sector collaboration, environmental education, and improved waste management are essential to reducing pollution loads and preserving the sustainability of the Bukit Batu River's functions.

Abstract

Limbah sludge dari industri minyak bumi menimbulkan masalah lingkungan akibat penimbunan. Inovasi diperlukan untuk mengubahnya menjadi pupuk kompos bernilai ekonomi, dengan memanfaatkan kulit nanas sebagai sumber nutrisi dan pendegradasi polutan. Penelitian ini bertujuan untuk mengetahui potensi sludge sebagai pengganti tanah dalam kompos berbasis kulit nanas, dengan parameter pH dan suhu sesuai SNI. Penelitian ini menggunakan metode kuantitatif-deskriptif dengan 12 komposter (4 perlakuan rasio sludge-tanah: 0:8, 2:6, 4:4, 6:2 kg) selama 12 minggu. Data pH dan suhu dianalisis dengan regresi linear. Semua komposter memenuhi standar pH (SNI 7763:2018) pada minggu ke-8 dan ke-12, serta suhu (SNI 19-7030-2004) pada minggu ke-4, -8, dan -12. Sludge mempercepat kenaikan pH dan menstabilkan suhu. Penelitian membuktikan sludge minyak bumi dapat dijadikan bahan kompos ramah lingkungan, dengan rekomendasi optimasi komposisi, uji logam berat, dan integrasi teknologi seperti vermicomposting untuk penelitian selanjutnya.

Berunok sea cucumber has a nutritional content that can be utilized as a functional food ingredient. This study determined the characteristics of berunok sea cucumber hydrolysate (Paracaudina australis) and the type and level of total amino acids. This research was conducted using experimental methods, with a Non-Factor Complete Randomized Design consisting of 3 levels of enzyme concentration treatment (1%, 2%, and 3%) with three replicates. In this study, the parameters tested were the proximate content of flour and hydrolysate of berunok and the type and content of total amino acids. The results showed that the chemical composition of berunok flour was water 11,40% (dw), ash 10,82% (dw), protein 68,21% (dw), fat 6,53% (dw), and carbohydrate by the difference of 14,43% (dw). The best treatment for preparing berunok protein hydrolysate using pepsin enzyme is 2% pepsin enzyme concentration. The proximate of berunok protein hydrolysate is water 6.87% (dw), ash 8.45% (dw), protein 80,59% (dw), and fat 2,86% (dw). The results of the identification of types and levels of total amino acids found 17 kinds of amino acids with a total of 16.524% in hydrolysate berunok.

Abstract

Mantis shrimp carapace waste can be processed into chitin and chitosan as antibacterial. This study aims to determine the characteristics, and heating time of chitosan on the potential of chitosan as an antibacterial, and to obtain the best chitosan in increasing the durability of catfish meatballs. Experimental research method with the manufacture of chitin and continued with deacetylation with a long heating time to obtain chitosan. The analytical parameters consisted of chemical characteristics (moisture content, ash, and degree of deacetylation), the inhibitory power of chitosan against Escherichia coli and Staphylococcus aureus bacteria, and the effectiveness of chitosan on the quality of catfish meatballs. The results showed that the chemical characteristics of chitosan were water content (K1 3.72%, K2 4.65%, K3 5.24%), ash (K1 2.38%, K2 2.53%, K3 3.69%), and the degree of deacetylation (K1 54.31%, K2 78.04%, K3 79.51%). The results of the inhibition test of chitosan against Escherichia coli and Staphylococcus aureus bacteria using the well method showed an inhibition zone with values (K1 10.11 mm and 10.18 mm, K2 11.52 mm and 11.48 mm, K3 12.15 mm and 11. 70 mm, positive control 14.64 mm and 14.02 mm, negative control 9.25 mm and 7.35 mm). This value indicates that the activity of chitosan as an antibacterial is quite strong. The effectiveness of chitosan on the quality of catfish meatballs with 7% chitosan immersion and storage at room temperature showed that the TPC value of catfish meatballs with chitosan could prolong the shelf life of meatballs until day-2.

Abstract

This study aims to determine the secondary metabolic content of saponin contained in the active fraction of sea cucumber (Stichopus vastus) by using metabolic test reagents and thin-layer chromatography (TLC) analysis. The active fraction was given the reagent in the form of HCl 2N and strong acid then continued with analysis to determine the Rf value and lieberman-burchad reaction. The results of the metabolic reaction test showed that the active fraction contained steroidal saponin compounds characterized by the presence of a stable foam and the formation of a greenish-green color. TLC analysis produced a single stain with an Rf value of 0.9 and a bluish color reaction after being given Liberman-burchad which confirmed that the saponins contained in the active fraction of sea cucumbers were steroidal saponin.

Abstract

Graphical Abstract Highlight Research Chlorella indigenous from waters of Rokan River estuary was identified. The using of 4 chemicals KNO3, KH2PO4, MgSO4.7H2O and FeSO4.7H2O can reduce production cost and obtain an optimal medium formulation. The manipulated media was obtained can replace the commercial media of Chlorella Chlorella vulgaris contains high antioxidant activity.   Abstract Chlorella is a microalga that is rich in chlorophyll and antioxidants so it has the potential to be a functional food or health supplement; however, the quality of Chlorella depends on the nutrient composition in cultivation. The research aimed to evaluate the effect of different formulations in Chlorella cultivation on the content of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids and antioxidants. Furthermore, to analyse the profile of amino acids, fatty acids and secondary metabolism in the best formulation. The experimental design used was a non-factorial Completely Randomized Design (CRD) with 5 formulations in Chlorella cultivation: F-1, F-2, F-3, F-4, and F-5 by manipulating the use of 4 chemicals: KNO3, KH2PO4, MgSO4.7H2O and FeSO4.7H2O. The data obtained were analyzed descriptively and analysis of variance (ANOVA). The results showed that F-2 treatment with the use of 1.50 KNO3, 1.25 KH2PO4, 1 MgSO4.7H2O and 0.0498 FeSO4.7H2O (g/L) was the best treatment with the content of chlorophyll a 38.19 μg/mL, chlorophyll b 41.45 μg/mL, total chlorophyll 79.65 μg/mL, carotenoids 0.08 μg/mL, and antioxidants activity 49.52 mg/L (strong) which is the same as the F-1 treatment. In addition, Chlorella cultivated with the F-2 formula has 17 amino acid profiles with a total of 301.52 mg/g, 7 fatty acids 84.32 mg/g, and secondary metabolites, namely alkaloid 109.471 mg/L, flavonoid 82.111 mg/L, saponin 1342.222 mg/L, tannin 411,591 mg/L, and phenolic 151.889 mg/L. Therefore, the F-2 formulation can be developed for large-scale Chlorella cultivation and applied as a health supplement.
