AbstractCadmium can accumulate in the renal cortex and lead to renal failure. Hence, this study was designed to investigate lemon pepper’s kidney protection effect against cadmium toxicity. Twenty-five male Wistar rats were grouped into five groups viz. Control (0.5% Na-CMC), standard (25 mg/ kg BW quercetin), Lemon Pepper methanol extract (LPME)-1 (300 mg/ kg BW), 2 (600 mg/ kg BW), and 3 (1,200 mg/ kg BW). These interventions were performed for 14 days; at the first seven days, all rats received some interventions based on intervention group without cadmium administration followed by cadmium administration for the next seven days. After that, all rats were sacrificed for kidney function tests and histology studies. The highest BUN level was found in the control group (103.20 ± 3.11 mg/dL) and the lowest was the standard group (57.60 ± 2.41 mg/dL). Meanwhile, the highest creatinine levels were found in the control group (1.06 ± 0.02 mg/dL), and the lowest was found in the standard group (0.83 ± 0.07 mg/dL). Moreover, the LPME-3 group also rescued some glomerular structures and reduced cyst formation due to severe kidney damage. Therefore, it can be concluded that the lemon pepper had a kidney protection effect against cadmium toxicity.

Abstract
Motile Aeromonas Septicemia has become a problem in aquaculture. This study set out to investigate the usefulness of the probiotic Lactobacillus acidophilus and Staphylococcus lentus on survival rate, growth, and feed conversion efficiency of African Catfish (Clarias gariepinus). In vitro test was carried out to evaluate the effectiveness of probiotic against A. hydrophila and followed by in vivo test. In earlier treatment, Aeromonas hydrophila (final concentration 104 CFU mL−1), L. acidophilus, and S. lentus at a final concentration of 104 CFU mL−1 were added in aquaria every 2 days. there are four of the aquaria with three replicates, one control (without probiotic). In vitro test exposed the inhibition zone of L. acidophilus, S. lentus, and the combination of both bacteria was 11.72±0.55, 13.03±2.99, and 14.66±1.50 mm, respectively. After 21 days of treatment, the addition of the probiotic significantly increased the survival rate (P<0.05) for all conducts compared with controls. In vivo test showed that the application of probiotics in media of cultivation could reduce the number of A. hydrophila, improve the specific growth rate (SGR 6.00 ± 0.05%), and also increase the survival of catfish compared to the positive control. The results indicated that the combination of probiotics L. acidophilus and S. lentus appearances the highest survival (91.11 ± 1.53 %) of all treatments and the ratio of feed conversion was found to be decreased (0.23).

Published: October 2022

Abstract
Swallow’s nest is made from the saliva of swallows, especially from the genus Collocalia. Swallow’s nest is usually used traditionally to improve health by the community. Swallow’s nest products are difficult to produce, causing the product price to be expensive. This study aims to identify the production costs and benefits of swiftlet nests using the Greedy algorithm by finding solutions for each stage of production. The principle of Greedy’s algorithm is "take what you can get now". There are 6 processes in the production of swiftlet nests, namely sorting raw materials, cleaning, drying, printing, in process control, and packaging. In the sorting and cleaning process, employees in the medium to light nest category are combined. The identification results show that the total costs incurred in the sorting and cleaning process are reduced by 14% and 8%, respectively. The process of drying dense and medium hair nests takes the same time so that it is carried out simultaneously and the required cost is reduced by 11%. The original molding stage and the nest supertype are combined because they have 90% similarity in the production process.
