ANTIDIABETIC POTENTIAL OF SOLID LIPID NANOPARTICLES (SLNS) FROM KABAU SEED (ARCHIDENDRON BUBALINUM (JACK) I.C. NIELSEN) EXTRACT COATED WITH TRIMYRISTIN
Get PDFType 2 diabetes mellitus is a global health problem that continues to increase. One alternative approach in managing diabetes is using natural materials with antihyperglycemic activity. This study aims to evaluate the effectiveness of solid lipid nanoparticles (SLN) containing Kabau seed extract (Archidendron bubalinum (Jack) I.C. Nielsen) coated with trimyristin in reducing blood glucose levels in hyperglycemic rats. Extraction was carried out by maceration using 96% ethanol, while SLN was synthesized by high-speed homogenization and ultrasonication methods. Particle size analysis showed an average diameter of 262.61 nm with a polydispersity index (PDI) of 0.144, indicating a homogeneous formulation. Phytochemical testing showed that Kabau seed extract contains alkaloids, flavonoids, tannins, and saponins contributing to antihyperglycemic activity. In vivo tests on Mus musculus showed that 20 % concentration of Kabau SLN reduced blood glucose levels by up to 97 mg/dL, approaching the effectiveness of metformin (104 mg/dL). Statistical analysis of ANOVA and BNT test showed significant differences between treatments. These results indicate that Kabau SLN has the potential as a candidate for phytopharmaceuticals in managing type 2 diabetes mellitus.

Correlation and Regression Between Body Measurements and Body Weight of Ongole Crossbred Cattle in Various Age Groups
Get PDFThis study aimed to estimate the value of genetic correlation and the regression equation between body weight and body measurements of male Ongole crossbred (PO) cattle across various age groups. The sample used consisted of 80 male PO cattle divided into four age groups: I0 (<18 months), I1 (18 to 24 months), I2 (24 to 30 months), and I3 (>30 months). The parameters observed include body weight (BW), body length (BL), body height (BH), hip height (HH), and chest circumference (CC). Correlation and regression data were analysed using the Excel program; the regression between body weight and body size was analysed using the best subset regression method. The results showed a strong to robust genetic correlation between body weight and body size, with the highest correlation value in chest circumference (CC) in all age groups (0.92-0.98). The regression equations revealed that chest circumference had the highest regression coefficients (ranging from 2.36 to 3.87), indicating that it is the most reliable body size measurement for predicting body weight in PO cattle. This study concludes that chest circumference can be used as a reliable parameter to estimate the weight of PO cattle in various age groups, especially for farmers who do not have access to scales
Diversity of Land Arthropods in Community Oil Palm Plantations in the Coastal Area of Bengkulu
Get PDFBengkulu is one of the provinces located on the island of Sumatra, boasting a significant agricultural sector. One of the leading agrarian commodities in Bengkulu Province is oil palm. Oil palm in Bengkulu is planted in coastal areas. One of the key factors supporting oil palm fruit production is a healthy soil arthropod ecosystem. Soil arthropods play an essential role in the oil palm plantation ecosystem. As organisms that live in the soil, these animals help maintain soil and plant health, improving soil structure and nutrient availability for oil palm plants. This study aims to obtain initial data on the diversity of soil arthropods and their roles in smallholder oil palm plantations on the coast of Bengkulu. This study began with sampling oil palm plantations around the coast of Bengkulu. The areas that will be used as study locations include Sungai Suci, Danau Gedang, and Pekik Nyaring. Arthropod sampling was carried out by installing pitfall traps in both areas, which were determined diagonally in a 200 m² area, with 20 pitfall trap units per location. Arthropod species were identified based on morphology, and the type and number of populations were recorded. The Shannon-Wiener diversity index, dominance index, and evenness index measure analysis of biodiversity data. The results of the study showed that in the majority, the diversity of soil arthropods in the three sampling areas was moderate, the dominance of arthropod types was low to moderate, and evenness was moderate to high
