Abstract

Abstract:The aim of this reserch is to know the corelation of emotional intelligence and pedagogical competence of kindergarten teachers sub-district Tenayan Raya. The population in this study were kindergarten teachers with a Bachelor of Education background (S1) in formal and non-formal institutions totaling 78 teachers, the sample of this study was 58 teachers. Method of this research is Pearson product moment correlation to see relationship between variables of work emotional intelligence and pedagogical competence. The technique of collecting data used tests and quistioner in Likert scale form. The technique of analyzing data used scale test and statistic analitical by using SPSS program for Windows Ver.17. Based of this research there is level of emotional intelligence of teachers is in the high category with empirical values of 71,88 and the level of pedagogical competence is in the moderate category with empirical values of 30,45. Based on the hypothesis test, there is a positive and significant relationship between emotional intelligence and pedagogical competence of kindergarten teachers Tenayan Raya District. This can be seen from the correlation coefficient of rxy = 0.566 and the significance level of 0.000 <0.05. The level of the relationship between emotional intelligence and pedagogical competencies is included in the medium category with the determinant coefficient value of KD = r² x 100% = 32%, meaning that emotional intelligence has an effect of 32% on pedagogic competence.Key Words : Emotional Intelligence , Pedagogic Competence

Abstract

Bengkal (Nauclea subdita (Korth.) Steud) is a medicinal plant that has been traditionally used for various treatments and is known to contain a wide range of secondary metabolites. However, most previous studies have focused only on the leaves, so information regarding the phytochemical composition of other plant parts remains very limited. This research is important to provide a comprehensive overview of the bioactive contents in all morphological parts of N. subdita, which have the potential to support the development of biological and pharmacological applications, such as antibacterial, antioxidant, antidiabetic, and anticancer activities commonly associated with alkaloids, flavonoids, and phenolic compounds. Secondary metabolite analysis was conducted on the leaves, roots, stems, and bark using phytochemical screening. Samples were collected from Ketapang, West Kalimantan, then dried, ground, and extracted using sequential maceration with n-hexane and ethanol. The extracts were subsequently fractionated with dichloromethane (DCM) at pH 3 and pH 9. Moisture content was determined using the gravimetric method. Phytochemical screening was carried out using standard qualitative tests, including Mayer’s and Wagner’s tests for alkaloids, color tests for flavonoids and phenolics, the Liebermann–Burchard test for triterpenoids, the FeCl₃ test for tannins, and the foam test for saponins. The results showed that all parts of the plant contain alkaloids, flavonoids, phenolics, and triterpenoids, although there were variations among extracts and fractions. Tannins were detected only in the leaves, while saponins were found in the leaves, roots, and stems. These findings confirm that all parts of N. subdita possess important biological potential due to the presence of major bioactive compounds that play a role in the development of herbal medicines and nature-based therapeutic agents. This information serves as a significant initial foundation for further pharmacological research.
