Abstract

These work aims are to determine the best condition extraction and product quality of quercetin from Carica papaya L flowers extract. The extraction of quercetin from Carica papaya L flowers had done by microwave-assisted extraction (MAE) method. Dried flowers prepared by cutting into 0,125 mm of particle size. Dried flowers were extracted using methanol 80% (w/w) to determine influence of solid to liquid, S/L, ratio (1:10, 1:15, 1:20), microwave power (120, 200, 280, 400 W), and extraction time (1-5 minutes) on extraction process. Using the phytochemical test by Mg-HCl-amyl alcohol and UV-Vis spectrophotometer techniques, the quercetin detected by qualitative and quantitative analysis. As a result, the presence of flavonoids detected by the formation of a brownish red-colored flavylium compound. Increasing extraction time, power, and S/L ratio increased the extraction temperature. Consequently, yield quercetin decreased when the temperature extraction exceeds its temperature degradation. The highest quercetin yield, 0.214%, was detected with solid to liquid ratio (1:15), microwave power (400 Watt), and extraction time (4 minutes). FTIR spectrophotometer technique on the highest yield quercetin proved that have product quality with 91,17% similarity on group function like OH, C=O, C=C, and C-H with quercetin standard spectrum.

Abstract

Biofloc in shrimp aquaculture provides natural food and reduces the reliance on commercial feed. The extent to which biofloc can optimize feeding management is not, however, fully understood. This study aimed to evaluate the effects of reducing feeding rates on the growth performance and feed utilization of Pacific white shrimp (Litopenaeus vannamei) reared in a biofloc system. A completely randomized design was used with four treatments: K (standard feeding, clear water), N (standard feeding, biofloc), NA (25% feeding reduction, biofloc), and NB (50% feeding reduction, biofloc). Shrimp were stocked at 40 individuals per tank and fed commercial feed containing 40% protein over a 30-day period. Results showed that shrimp in the NA treatment (25% feed reduction with biofloc) had the highest final weight (8.66 ± 0.03 g), biomass (306.13 ± 14.27 g), and weight gain (5.74 ± 0.25 g) compared to other treatments (P<0.05). NA also exhibited a higher specific growth rate (3.63 ± 0.27 %/day) than K and NB. Feed utilization improved with a lower feed conversion ratio and higher protein retention in the NA group. This study highlights that a 25% feeding rate reduction in biofloc systems optimizes shrimp growth and feed utilization. Future research should explore long-term sustainability, biofloc composition variations, and technological integration for scaling up efficient and environmentally sustainable shrimp farming operations.Penggunaan bioflok dalam budidaya udang memberikan makanan alami dan mengurangi ketergantungan pada pakan komersial. Namun, sejauh mana bioflok dapat mengoptimalkan manajemen pakan belum sepenuhnya dipahami. Penelitian ini bertujuan untuk mengevaluasi efek pengurangan laju pemberian pakan terhadap kinerja pertumbuhan dan pemanfaatan pakan udang vaname (Litopenaeus vannamei) yang dibudidayakan dalam sistem bioflok. Desain penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan, yaitu: K (pemberian pakan standar, air jernih), N (pemberian pakan standar, bioflok), NA (pengurangan pakan 25%, bioflok), dan NB (pengurangan pakan 50%, bioflok). Udang ditempatkan sebanyak 40 individu per tangki dan diberi pakan komersial yang mengandung 40% protein selama 30 hari. Hasil menunjukkan bahwa udang pada perlakuan NA (pengurangan pakan 25% dengan bioflok) memiliki berat akhir tertinggi (8,66 ± 0,03 g), biomassa (306,13 ± 14,27 g), dan kenaikan berat (5,74 ± 0,25 g) dibandingkan perlakuan lainnya (P<0,05). NA juga menunjukkan tingkat pertumbuhan spesifik yang lebih tinggi (3,63 ± 0,27 %/hari) dibandingkan K dan NB. Pemanfaatan pakan meningkat dengan rasio konversi pakan yang lebih rendah dan retensi protein yang lebih tinggi pada kelompok NA. Penelitian ini menunjukkan bahwa pengurangan feeding rate pakan sebesar 25% dalam sistem bioflok mengoptimalkan pertumbuhan udang dan pemanfaatan pakan. Penelitian di masa depan harus mengeksplorasi keberlanjutan jangka panjang, variasi komposisi bioflok, dan integrasi teknologi untuk meningkatkan praktik budidaya udang yang efisien dan ramah lingkungan.

Abstract

Recently, renewable energy sources are needed to meet human energy needs, one of which is bioethanol. Bioethanol can be made from banana peels. Banana peel contains starch which has the potential to be converted into bioethanol through fermentation. There are factors that affect fermentation including the number of microorganisms and glucose levels. One method to increase glucose levels is hydrolysis. The purpose of this study was to determine the effect of hydrolysis and the amount of yeast on bioethanol levels in banana peel fermentation. The research variables used were hydrolyzed and non-hydrolyzed banana peel substrates, as well as variations in the amount of yeast as much as 3 grams; 4.5 grams; and 6 grams. From this research, it was found that hydrolysis causes an increase in glucose levels in the substrate due to the conversion of starch to glucose. Increased glucose levels can affect the yield of bioethanol. The bioethanol content of the hydrolyzed substrate fermentation is 9%-9.5% greater than the bioethanol content of the non-hydrolyzed substrate fermentation of 3%-3.5%. The difference in the amount of yeast used in banana peel fermentation has an effect on the bioethanol content but not significantly enough because the amount of yeast will depend on the glucose content in the substrate.

Abstract

The use of carbon monoxide (CO) in the fishing industry to improve the bright red color of fish fillets has been controversial. Despite its effectiveness and buyer demand, CO results in food safety risks and there are strict regulations in some countries. The objective of this study was to examine the effectiveness of ascorbic acid as a substitute for CO to enable products to penetrate the European Union market. The research method employed was a combination of organoleptic and microbiological testing of Goldbanded Jobfish fillets treated with CO, whereas treatment with ascorbic acid was only evaluated through organoleptic testing. The results showed that the use of CO in Goldbanded jobfish fillets resulted in bright red color and a soft texture. However, European countries prohibit the injection of CO in meat products, so the fisheries industry cannot export Goldbanded jobfish (Pristipomoides multidens) fish fillets to the European Union. Therefore, innovation in natural ingredients is needed to maintain the red color of fish fillets. The addition of 0.03% ascorbic acid, can maintain the bright red color of fish fillets and produce a firm and dense texture. To our knowledge, this research is the latest alternative solution to replace CO gas adjuvant in improving the texture of frozen Goldbanded jobfish products.
