The Phytase and Microbial Potential in Fish Feed: A Review
Get PDFPhytic acid is a form of phosphorus storage that can interfere with the absorption of starch and protein as an energy source from cereal grain flour. This review aims to explore the benefits of microbial fermentation processing in producing phytase enzymes to degrade phytic acid and improve the nutritional quality of grain-based fish feed. Through a comprehensive literature study approach, reviewing the mechanism of phytase production, characteristics of potential microbes, and fermentation process optimization strategies that can affect the effectiveness of enzymes in reducing phytic acid content. The results of the study showed that the microbes Bacillus subtilis, Aspergillus niger, and Lactobacillus plantarum have the potential to produce phytase. Optimization of environmental conditions in fermentation and phytase application is influenced by media composition, environmental parameters, microbial strains and fish species, becoming the key to the success of effective enzyme application. Optimal fermentation conditions range from pH 4.5-6.5 and temperature 45-55℃. Addition of phytase with a dose of 0.75-2 g/kg feed can increase growth. Phytase can increase digestibility and is effectively needed (range 500-1500 mg/kg) in farmed fish

Analysis of the Biological Quality of Clean Water in the Male Dormitory
Get PDFThe use of unclean water is one of the causes of skin diseases. Skin diseases are often suffered by students in the Islamic boarding school environment because sanitation facilities may be inadequate. It is known that the water source in the Islamic boarding school uses drilled well water. The purpose of this study was to determine the quality of clean water in the male dormitory of the Abu Hurairah Mataram Islamic boarding school, which was reviewed biologically. This type of research is descriptive qualitative. The population in this study were all the water taps in the male dormitory of the Abu Hurairah Mataram Islamic boarding school. Based on the results of biological quality tests, including Coliform tests and Eschericia coli tests on water, it is known that the coliform test results obtained in sample A were 18 MPN / 100ml, sample B was 46 MPN / 100ml, sample C was 230 MPN / 100ml, and sample D was 0 MPN / 100ml and the results of Eschericia coli in sample A were 24000 MPN / 100ml, sample B was 24000 MPN / 100ml, sample C was 0 MPN / 100ml, and sample D was 0 MPN / 100ml. The water used by students still cannot be said to be suitable for use because of the presence of Escherichia coli and Coliform bacteria that can cause disease in humans. There needs to be treatment to reduce the bacterial content in sanitation facilities in Islamic boarding schools
Relationship Between BMI, Hemoglobin Levels, and Dur ation of Hemodialysis with Blood Pressure Changes Pressure at Praya Hospital
Get PDFHemodialysis (HD) is a kidney replacement therapy by filtrating blood outside the body using a dialysis machine. Intradialysis complications such as hypotension and intradialysis hypertension are one of the abnormal conditions that occur during the hemodialysis process. The purpose of this study in RSUD Praya was to evaluate the relationship between IMT, hemoglobin level, and duration of hemodialysis with changes in blood pressure during the hemodialysis process. This study used a cross-sectional approach and was observational quantitative analytic in nature. Sampling was done using the total sampling method. The sample size of this study was 45 samples. Data were tested using spearmen rank. The findings of 45 respondents, most of them have stable blood pressure 24 people (53.3%), while 10 people (22.2%) have decreased blood pressure, and 11 people (24.4%) have increased blood pressure. There was a significant correlation between body mass index and blood pressure changes (p=0.028). Hemoglobin levels were not associated with blood pressure changes (p=0.574). There was a strong relationship between hemodialysis duration and blood pressure changes (p=0.009). There is a relationship between BMI, duration of hemodialysis and blood pressure changes during hemodialysis process and there is no relationship between hemoglobin levels and blood pressure changes during hemodialysis process. The conclusion is that body mass index and duration of hemodialysis affect blood pressure changes in hemodialysis patients at Praya Regional Hospital, while hemoglobin levels have no influence on blood pressure changes in hemodialysis patients at Praya Regional Hospital

Phytochemical Profiling of Tampoi (Baccaurea macrocarpa (Miq.) Mull. Arg.) Leaves Using Liquid Chromatography-Tandem Mass Spectrometry
Get PDFTampoi leaves (Baccaurea macrocarpa (Miq.) Mull. Arg.) have been reported to contain a diverse array of phytochemicals associated with various biological activities, including antioxidant and antibacterial effects, as well as the enhancement of erythrocyte and hemoglobin levels in anemic mouse models. This study aimed to comprehensively characterize the phytochemical profile of tampoi leaves to establish a foundation for elucidating the mechanisms underlying their biological activities. Extraction was conducted using a solid phase method with methanol as the solvent. Phytochemical profiling was performed using Liquid Chromatography Tandem Mass Spectrometry (LCMS/MS) in positive ionization mode, and data analysis was carried out using MassLynx software. The analysis revealed the presence of 39 phytochemical compounds in the methanolic extract of tampoi leaves. These compounds were classified into 12 major groups: coumarin, amino acid, glycosides, flavonoids, inositol, tannin, terpenoids, jasmonic acids, alkaloids, saponin, phenols, and fatty acids. Among these, terpenoids constituted the most abundant class, comprising nine compounds. Vitexin and linolenic acid exhibited the highest chromatographic peaks, indicating relatively high abundances compared to other constituents in the extract. The phytochemical profile of tampoi leaves offers a valuable basis for understanding the interactions between bioactive compounds and biological targets through in silico approaches, thereby supporting the development of phytopharmaceutical candidates
