Abstract

This study aims to determine the effect of Rosella flower extract (Hibiscus sabdariffa L.) on uric acid levels in White Rats (Rattus norvegicus) induced by LDL. The research method used is the Laboratory experiment method with a Completely Randomized Design (CRD) pattern. The number of samples used was 21 White Rats consisting of 7 treatment groups and 3 replications. The normal control group (KN) is a group that is only given food and drink, the negative control group (K-) is given LDL induction for 30 days, the positive control group (K+) is given LDL induction for 30 days and allopurinol, and the group given LDL induction for 30 days and Rosella flower extract, namely concentrations of 25% (PI), 50% (PII), 75% (PIII), and 100% (PIV) for 14 days. The data obtained were tabulated and analyzed using one-way ANOVA statistical test using SPSS version-30. The results showed that Rosella flower extract had a significant effect (p <0.05) on reducing uric acid levels. The effective concentration for reducing uric acid levels is a concentration of 50% (PII) compared to concentrations of 75% and 100% because there are chemical compounds that are antagonistic to the active compound, thus reducing the extract's ability to reduce blood uric acid levels. The results of the Rosella flower study can reduce uric acid levels so that it can be used as an alternative natural treatment.

Abstract

This study aims to determine the effect of rosella flower extract on reducing blood glucose levels in alloxan-induced white rats. The research method used is an experiment conducted in the laboratory with a complete randomized design (RAL) pattern. The number of samples used was 24 white rats consisting of 6 treatment groups and 4 replicates. Normal control group (Kn) is a group that is only given food and drink, negative control group      (K-) is a group given alloxan induction, positive control group (K+) is a group given alloxan induction and metformin synthesized drug, treatment groups I, II, and III are groups given alloxan induction and rosella flower extract at a dose of 50 mg/kg BB, 100 mg/kg BB and 150 mg/kg BB. The data obtained were analyzed by ANOVA statistical test. The results showed that rosella flower extract had an effect on reducing blood glucose levels in white rats induced by alloxan. The most effective dose in reducing blood glucose levels in white rats is a dose of 150 mg/kg.

Abstract

This study aims is to identify the types of ectoparasites affecting Nile tilapia (Oreochromis niloticus). This research employed a survey method with purposive sampling technique. Fish samples were collected from two different locations, namely a tarpaulin pond and a soil pond in Binangga Village, Marawola District, Sigi Regency. Ten fish were sampled from each location and subsequently identified in the Biology Education Laboratory at Tadulako University. Observations were made on the external parts of the Nile tilapia, including the mucus, gills, fins, and tail. The parameter observed was the type of ectoparasite infecting the Nile tilapia. The results indicated the identification of five ectoparasite species: Dactylogyrus sp., Gyrodactylus sp., Attheyella sp., Cichlidogyrus sp., and Unitubulotestis sardae in 20 Nile tilapia samples. The highest prevalence of ectoparasites was found in the tarpaulin pond. However, both the tarpaulin and soil ponds shared one common ectoparasite species, Unitubulotestis sardae. The conclusion of this study is that Nile tilapia in both locations are infected by various ectoparasite species, with differences in prevalence between the tarpaulin and soil ponds.
