Abstract

Purpose of the study: This research aims to improve students' understanding of mathematical concepts in number competency by using the Team Assisted Individualization (TAI) Learning Model in class IV B SDN No. 64/1 Muara Bulian. Methodology: This research is a study that consists of 2 cycles. This type of research uses a mixed method, namely a combination of quantitative and qualitative research. The research subjects were students of class IV B at SD Negeri 64/1 Muara Bulian. The data obtained are quantitative data and qualitative data. Data collection techniques were obtained through observation and interviews. Then the data were analyzed based on the type of data obtained. Main Findings: The study's findings showed that students' understanding of concepts increased from 60.35% in cycle I to 84.86% in cycle II. So that the use of the Team Assisted Individualization (TAI) learning model can help improve students' conceptual understanding of number competence in class IV B SDN NO. 64/1 Muara Bulian. Novelty/Originality of this study: The update in this research is contained in the results of this research, where the studies in this article are the latest results in the field of science, especially mathematics education. With this research, readers and other researchers can determine the impact of using the Team Assisted Individualization (TAI) learning model on students' understanding of mathematical concepts in elementary schools, especially in number competency material.

Abstract

This study aims to examine the effect of fertilizer concentration on the growth of land kale. The research method chosen was a simple completely randomized design (CRD).The plant samples consisted of 6 groups, each consisting of 5 plants, with 1 group as the control group and the remaining 5 groups as the experimental group. The experimental group was treated with varying concentrations of liquid fertilizer from 2.44% by volume, 4.76% by volume, 6.98% by volume, 9.10% by volume up to 11.11% by volume and observations of plant growth were carried out once every 4 days for 5 period. Based on the plant height results, the experimental group produced the highest average plant in sample E with a concentration of 11.11% by volume. As for the number of leaves parameter, the highest number of leaves was also obtained in the experimental group sample E. Based on the results of analysis of variance using the Anova Test, it was found that the results of Fcount>Ftable were good in the analysis of the effect of fertilizer concentration on plant height and number of leaves. So that the use of liquid fertilizer has a significant effect on the growth of land kale (Ipomea reptans. Poir).
