The Influence Of Maceration Time And Ethanol Volume On Total Flavonoid Content Of Luffa cylindrica Fruit Extract
Luffa cylindrica is a potential source of bioactive compounds, particularly flavonoids, which are known for their antioxidant and health-promoting properties. However, information regarding optimal extraction conditions for maximizing flavonoid yield from L. cylindrica fruit remains limited. Therefore, this study aimed to evaluate the effect of solvent volume and maceration time on the total flavonoid content of L. cylindrica fruit extract. Extraction was performed using the maceration method with 70% ethanol at solvent volumes of 750, 1000, and 1250 mL, and maceration times of 3, 5, and 7 days. Total flavonoid content was determined quantitatively using the aluminum chloride colorimetric method and measured by UV–Visible spectrophotometry, with quercetin used as the standard. Flavonoid content was expressed as milligrams of quercetin equivalent per gram of extract (mg QE/g). The results showed that both solvent volume and maceration time significantly affected total flavonoid content (p < 0.05). Flavonoid levels ranged from 1.12 to 3.15 mg QE/g, with a clear increasing pattern observed as solvent volume and maceration time increased. The highest flavonoid content (3.15 mg QE/g) was obtained using a solvent volume of 1250 mL and a maceration time of 7 days. In conclusion, increasing solvent volume and extending maceration time effectively enhanced flavonoid extraction from L. cylindrica fruit. The maceration method using 70% ethanol is a simple, effective, and economical approach for flavonoid extraction from this plant.

Optimasi Pertumbuhan Bakteri Laut Penghasil Protease Menggunakan Variasi Konsentrasi Media Skim Milk Modifikasi
This study aims to analyze the growth rate of marine bacteria producing protease using variations in the concentration of skim milk media and to observe the relationship between cell growth and enzyme activity. The study was conducted using three concentrations of skim milk media (1%, 2%, and 3%) and observation of growth and enzyme activity for 108 hours. The results showed that 1% skim milk concentration produced the largest proteolytic zone diameter (13.8 mm) with the fastest growth (1 day). Observations of cell growth patterns and enzyme activity showed that the highest enzyme activity (0.5933 U/mL) occurred in the early growth phase and decreased in subsequent phases even though cell growth increased. This indicates that there is no linear relationship between cell growth and enzyme activity in marine bacteria-producing protease, where enzyme production and activity are influenced by various complex factors such as physiological conditions of the cells and nutrient availability.
Aktivitas Antibakteri Infusa Daun Mangga Bacang (Mangifera foetida) Terhadap Bakteri Aeromonas hydrophila
Aeromonas hydrophila is an infectious agent that triggers Motile Aeromonas Septicemia (MAS) in freshwater fish, including catfish, leading to significant economic losses in aquaculture. This study aims to evaluate the antibacterial activity of Mango Bacang (Mangifera foetida L.) leaf infusion against A. hydrophila and its effect on catfish mortality. The research methods included the preparation of the infusion, phytochemical screening, antibacterial activity testing, and assessing the infusion's impact on catfish mortality. Phytochemical screening revealed that Mango Bacang leaf infusion contains alkaloids, flavonoids, phenols, tannins, and saponins, contributing to its antibacterial properties. The well-diffusion technique used to examine antibacterial effects demonstrated that the infusion at concentrations of 5–100% produced significant inhibition zones against A. hydrophila, with strong activity observed at a 5% concentration (14.38 ± 1.67 mm). However, toxicity testing on catfish indicated increased mortality with higher infusion concentrations, reaching 50% at 5% concentration. These findings suggest that Mango Bacang leaf infusion has potential as a natural antibacterial agent to control A. hydrophila, but its use requires precise dosage management to ensure safety for catfish. Further studies are necessary to optimize effective and environmentally friendly concentrations and explore applications on a broader scale.

Using the experimental method Completely Randomized Design (CRD), with 5 treatments namely P0 (control), P1 (100ml/L water), P2 (150ml/L water), P3 (200ml/L water), and P4 (250ml/L water) ), The treatment was repeated 4 times and the results showed that the best concentration was in the P4 treatment with a dose (250 ml/L of water) for plant height (14.87), number of leaves (12) and stem diameter (0.65).
Kelimpahan Dan Pola Pertumbuhan Kerang Bulu (Anadara antiquata) di Perairan Gunung Riting Kabupaten Belitung
Gunung Riting waters are located in Belitung Regency which has high water biota resource potential. One biota that has a high economic value is the feather shell (Anadara antiquata). Feather shells generally live in muddy waters in shallow waters with a high turbidity levels and are one of the important commodities that are very potentially developed. The purpose of this study was to find out the abundance, growth patterns and water quality in the waters of gunung which is the habitat of feather shells. The study was conducted from December 2019 to January 2020 at 3 sampling stations, sampling using the transect method. The results of the study obtained that the highest number of feather shells found in the waters of gunung riting obtained at Station 2 is 506 feather shells with an abundance of 33.73 individuals/m2, the pattern of growth of feather shells in the waters of gunung riting has an negative allometric growth pattern where long growth is more dominant than weight growth and the water quality obtained is able to support the growth and abundance of feather shells in the waters of gunung riting.

Research on the morphology of insects attracted to color traps was carried out in April-June 2023, aiming to study the interest of insects to color and their morphology in red chili plantations, Pedu Village, Jejawi Sub-district, OKI District. This study used a survey method. Sampling by purposive sampling. The color traps used are red, yellow, green and blue. The observation parameter is the number of trapped insect species. Many insects are housed both in the number of species and in the number of individuals of each species. The results of the study found 11 insect species namely, Bactrocera dorsalis, Epilachna sp, Periplanetta americana, Bemisia tabaci, Nezara viridula, Valanga nigriconis, Odontomachus sp., Musca domestica, Agelastica alni, Oxya chinensis, Polistes sp. scattered in red 8 species, yellow 8 species, green 8 species, and blue 1 species. Mouth morphology types include chewing, sucking, piercing-sucking, biting-sucking, and biting-chewing. Head morphology types include hypognathus, prognathus, and opistrorincus types. Antenna morphology types include filiform, clavate, pectinate, aristale, and geniculate types. Wing morphology types include membrane, elytra, halter, and tegmina types. The morphological types of insect violations include cursorial, saltatorial, raptatorial, and natatorial types. 81% of pests, 9% of saprophagus and 9% of pollinators get the role of insects.
Perbedaan Nilai Indeks Eritrosit Pada Sampel Darah Vena Dengan Pengambilan Posisi Duduk Dan Posisi Berbaring
The erythrocyte index or Mean Cospuscular Value is an average value that can provide information about the average erythrocyte and the amount of hemoglobin per-erythrocyte. The erythrocyte index consists of Mean Corpuscular Volume (MCV) or the average volume of an erythrocyte, Mean Corpusculara Hemoglobin (MCH) or the amount of hemoglobin per-erythrocyte, Mean Corpuscular Hemoglobin Concentration (MCHC) or the concentration of hemoglobin obtained per-erythrocyte. Erythrocyte index examination is more specifically used to determine what type of anemia is suffered by someone who experiences it. This study aims to determine the difference in the results of the examination of erythrocyte index values in venous blood sampling by taking sitting and lying positions. This research method is Crossectional, research conducted at Bunda Hospital Palembang. The population taken was female students of the S.Tr study program. Medical Laboratory Technology Muhammadiyah Palembang, Samples used in this study amounted to 31 samples using Purposive Sampling. The study obtained the results of MCV sitting position 84.88 and lying position 84.34 fl, MCH obtained an average value in sitting position 28.09 and lying position 28.05 pg / cell and MCHC examination obtained an average value in sitting position 33.05 and lying position 33.22 g / dl which means there are differences in erythrocyte index examination in venous blood sampling with sitting position and lying position. It can be concluded that venous blood sampling in the sitting position is not recommended for erythrocyte index examination, because the examination results are different in the sitting position.
