Abstract

This study aims to determine the effect of Problem Based Learning (PBL) learning model on students' biology problem solving skills in class VIII SMP Negeri 19 Palu. The method used was a quasi-experiment with Non equivalent (Pretest and Posttest) Control Group Design. The research sample amounted to 46 students, consisting of 23 experimental class students who used the PBL model and 23 control class students who used the conventional learning model. Data were collected through observation, teacher and student activity assessment sheets, and tests in the form of valid and reliable description questions. Data analysis was carried out with prerequisite tests, namely normality test and homogeneity test, as well as hypothesis testing using Independent Sample t-test. The results showed that there was a significant effect of PBL model on students' biological problem solving ability. The average posttest score of the experimental class reached 91.73, while the control class was only 75.21. The t-test shows a p value <0.05, which means that the alternative hypothesis is accepted, indicating that the application of the PBL model has a positive effect. Thus, it can be concluded that the PBL model is effective and influential on students' biology problem solving skills in science subjects of class VIII-D SMP Negeri 19 Palu.

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 identify the types of medicinal plants, parts of medicinal plants and the processing of medicinal plants used by the Kaili Tribe in Sipi Village, Sirenja District, Donggala Regency, Central Sulawesi. The type of research used in this study is descriptive qualitative with the snowball sampling method. The sampling technique used the roaming method and free collection. The method of determining the sampling area using the roaming method of the research location, namely, explored from the initial boundary of hamlet 1 in the west to the boundary of hamlet 4 in the east in Sipi Village. Data were collected through field observations, free interviews with people who have local knowledge about medicinal plants, and direct documentation. The results showed that there are 20 species of medicinal plants from 12 families that are used to treat various diseases such as diabetes, external wounds, tinea versicolor, toothache, digestive disorders, and others. The plant parts used include roots/rhizomes, stems, leaves and sap. The methods of utilization are various such as boiling, pounding, rubbing, chewing and drops. This research shows the importance of preserving traditional knowledge regarding the use of medicinal plants by local communities as part of local wisdom that is passed down from generation to generation.

Abstract

This study aims to identify the types of macroscopic fungi found in the forest area of Namo Village, Kulawi Subdistrict, Sigi Regency. The research employed an exploratory method with a free collection sampling technique. Sampling was conducted at three different stations: forest area, plantation, and residential settlement. The observational data were analyzed descriptively and identified using reference books, scientific publications, and the Google Lens application. The results of the study revealed a total of 30 species of macroscopic fungi, classified into two phyla, namely Basidiomycota and Ascomycota, encompassing 4 classes, 7 orders, and 16 families. The Basidiomycota phylum dominated with the highest number of species, comprising 21 genera, 14 families, and 5 orders. In contrast, the Ascomycota phylum consisted of only 2 genera, 2 families, and 2 orders. These findings indicate a high diversity of macroscopic fungi, highlighting the potential of these biological resources for educational purposes and further scientific research.

Abstract

Apart from being used as a food ingredient, water purifier or cosmetic ingredient, the moringa plant can also be used as a health drink in the form of moringa tea. Other benefits of moringa leaves are as a chemopreventive, increasing the body's endurance, nutrition for the eyes and brain, eliminating signs of wrinkles on the face, and as an antioxidant. However, unfortunately not all people know about the benefits of the moringa plant as a nutritious plant. This article is a literature review to analyze the benefits of moringa leaves as a health drink. The results of the literature analysis that has been carried out show that the moringa plant contains a number of important nutrients that are needed for body health.  The nutrients in moringa include vitamin C which is equivalent to seven times that of oranges, calcium equivalent to four times and protein equivalent to twice that of milk, vitamin A equivalent to four times that of carrots, and potassium equivalent to three times that of bananas. Apart from that, it also contains high levels of antioxidants, so the Moringa plant is very important for warding off free radicals. Several research results have found that moringa leaf extract can reduce blood glucose levels in white mice. People can be encouraged to use the moringa plant in their daily lives. Based on the explanation in this article, people can cultivate the use of moringa leaves as a drink to overcome health problems. Through the development of moringa plants as a typical plant and raw material for herbal tea in the Central Sulawesi area, communities can be empowered to utilize empty land to plant Moringa.
