PENGARUH DAUN JAMBU BIJI TERHADAP SIFAT MIKROBIOLOGIS DAN KIMIA NIRA GEWANG SERTA FISIK DAN ORGANOLEPTIK GULA CAIR
No full textThe sap of gebang (Corypha utan Lamk) is one of the basic materials in making liquid sugar in East Nusa Tenggara (ENT). The presence of microbial contaminant reduces the quality of the sap, therefore it need an effort to overcome the problem by using safety locally natural resource. One of this is the leaves of guava (Psidium guajava). A research has been conducted by using a simple Completed Random Design (CRD) with 4 treatments: gebang sap without guava leaves (DJ0), the sap with 1% (w/v) of guava leaves (DJ1), the sap with 1,5% (w/v) of guava leaves (DJ2), and the sap with 2% (w/v) of guava leaves (A3). The treatments were replicated 3 times. Parameters observed for the sap were total microbia, pH and total soluble solids (TSS); while the parameters for liquid sugar were water activity and organoleptic properties. The results show that adding guava leaves into the sap significantly reduces total microba, and increases the TSS of the sap as well as reduces the water activity of the liquid sugar; while organoleptically, the most acceptable of liquid sugar is found in the DJ1 treatment
Potential of Flavonoid Isolate from Okra Fruit (Abelmoschus esculentus L.) as Antidiabetic and Antilipase Agent In Vitro and In Silico
No full textObesity, which is currently a global issue that contributes to a number of diseases, including diabetes and coronary heart disease. This study set out to isolate and identify the flavonoid compounds from okra fruit that demonstrate the ability to inhibit alpha glucosidase and pancreatic lipase. Okra fruit powder was extracted using ethanol at a concentration of 80% following fractination with n-hexane, ethyl acetate, and aquadest. TLC preparation was used to isolate flavonoid from fraction ethyl acetate. Flavonoids that were succesfully isolated were quercetin compounds. The IC50 value of quercetin was found to be 47.9763 micrograms/mL. This was greater than IC50 acarbose as a positive control at a concentration of 33.8169 micrograms/mL, which showed its ability as an inhibitor -glucosidase was smaller. Quercetin acted as pancreatic lipase inhibitors, albeit weaker than the positive control Orlistat, which at the same concentration could inhibit 68% of pancreatic lipase activity, while quercetin could only inhibit 50%. Using molecular docking in silico testing, quercetin compounds were shown to have a stronger bond than the positive control. Similar to positive control, quercetin compounds could interact with receptors with amino acids residues GLU 277 (glutamic acid) and ASP 352 (aspartic acid), amino acids crucial in determining enzyme activity. Conversely, in the silico tests for pancreatic lipase inhibition, Orlistat displayed an exceedingly strong bond than quercetin compounds. Despite this, quercetin compounds also showed interaction between resceptors with amino acids residues MET 123 (Methionine) and ALA 51 (Alanine), amino acids that determine enzyme activity (catalytic site of enzyme
DETERMINANT OF EFFECTIVE TAX RATE: INSTITUTIONAL OWNERSHIP AS MODERATING VARIABLE
Get PDFResearch Purposes. This research examines how capital intensity, leverage, profitability, and sales growth influence effective tax rates, with institutional ownership as a moderating variable. The study measures these factors using Capital Intensity Ratio (CIR), Debt to Equity Ratio (DER), Return on Assets (ROA), Sales Growth (SG), and Institutional Ownership (KI).
Research Methods Employing quantitative methodology, the analysis uses multiple linear regression on data from 38 food and beverage companies on the IDX between 2021-2023. These companies were identified through purposive sampling techniques.
Research Results and Findings. The findings indicate that capital intensity and return on assets influence the effective tax rate, while debt-to-equity ratio and sales growth show no impact. Furthermore, institutional ownership successfully moderates how capital intensity and return on assets affect the effective tax rate. However, this institutional ownership fails to moderate the relationship between debt to equity ratio, sales growth, and the effective tax rate. Therefore, this research is expected to be useful for company management in order to find out what factors affect the amount of corporate tax payments and in an effort to streamline the company's tax burden according to applicable tax regulations. This research is also expected to be a source of reference and development material for further research in the future related to factors that affect the Effective Tax Rate in Indonesia

KETIKA KEBIASAAN MENJADI RISIKO: HUBUNGAN POLA MAKAN DAN AKTIVITAS FISIK DENGAN KEJADIAN DIABETES MELLITUS PADA ORANG DEWASA
Get PDFDiabetes Mellitus (DM) is a chronic disease characterized by high blood glucose levels due to the body’s inability to use insulin effectively. This condition creates an imbalance between the availability of glucose and the body’s needs for metabolism and cell growth. Dietary patterns include the types and amounts of food consumed to meet nutritional needs, which are influenced by attitudes, beliefs, and individual preferences. Physical activity refers to body movements produced by skeletal muscles that burn energy. To maintain health, it is recommended to engage in at least 30 minutes of moderate-intensity physical activity per day or 150 minutes per week. This study aimed to analyze the relationship between dietary patterns and physical activity with the incidence of DM. The research employed an analytical observational method with a cross-sectional design. It was conducted at Praya Health Center, Central Lombok Regency, involving 50 respondents aged 30–59 years, both with and without DM, selected through purposive sampling. Data were collected using a structured questionnaire and analyzed with Fisher’s exact test. The results showed no significant relationship between dietary patterns (p=0.170) and physical activity (p=0.713) with the incidence of DM. These findings indicate that, in this study population, both factors were not significantly associated with DM.
