Abstract

This study aims to describe the influence of parental income on students' learning motivation. This study uses a descriptive qualitative approach. The subjects of this study consisted of 30 students in grade VII. The results showed that the majority of students came from families with low incomes, and this had an impact on students' low learning motivation. The level of parental income influenced the learning motivation of students in the subject of science (Biology) in grade VII at SMP Negeri 20 Sigi. The researcher found several students whose parents had low incomes so that it influenced the students' learning motivation, from the 30 samples that the researcher used, there were 26 students with low incomes with incomes <Rp.500,000 and those with high incomes were 4 students with incomes of Rp. 1,000,000 - Rp. 1,999,999. The average student learning motivation only reached 36%, which is included in the very low category. Internal factors (31%) and external factors (42%) both play a role in decreasing students' learning motivation. Interventions such as scholarships and support from parents and schools are needed to increase students' enthusiasm for learning. Thus, it can be concluded that the learning motivation of class VII students at SMP Negeri 20 Sigi is very low.

Abstract

This study aims to inventory the types of macroalgae found in the hot springs of Marana Village, Sindue District, Donggala Regency. This research used descriptive quantitative method with free collection sampling technique. Sampling was carried out directly at five points of hot springs around the research location. Observation data were analyzed descriptively and identified using the determination key and the help of taxonomic images. The results showed that there were five types of macroalgae classified into three classes, namely Chlorophyta, Phaeophyta, and Cyanobacteria. Chlorophyta class (green macroalgae) consists of three species, namely Ulva lactuca, Cladophora glomerata, and Spirogyra sp. Phaeophyta class (brown macroalgae) consists of only one species, namely Saccharina latissima. The Cyanobacteria class (blue-green macroalgae) consists of one species, namely Noctos sp. The existence of these types of macroalgae indicates the existence of biodiversity that can be utilized as a source of environment-based learning and as basic information for further research in the field of aquatic ecology.

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.
