Abstract

Mathematics is one of the compulsory subjects in elementary school. Therefore, it is expected that by introducing Islamic values in mathematics learning, students can learn mathematics and understand the greatness of Allah SWT. This research is motivated by the lack of students' understanding of Islamic values instilled in mathematics learning because mathematics material lacks a connection with Islamic values. This research was conducted at SDN 100315 Sanggapati, East Angkola Subdistrict, South Tapanuli and all students are predominantly Muslim. This research is a qualitative research that uses data collection methods through observation at elementary schools, interviews with SDN 100315 Sanggapati teachers, and learning documentation according to the lesson plan. The purpose of the research is to find out the integration of Islamic values and mathematics education in developing students with Islamic character at SDN 100315 Sanggapati.

Abstract

Research on the Exploration and Characterization of Several Local Rice Plants in South Tapanuli Regency, North Sumatra Province. The purpose of this study is to determine the level of diversity and similarity of the phenotypic character of local rice plants with the exploration and identification of morphological characters in South Tapanuli Regency. Sampling was carried out randomly (purposive sampling) from South Tapanuli Regency. The data observed are in the form of quantitative data and qualitative data of local rice plants.  The results of the study show that rice cultivars are found in various areas in South Tapanuli Regency with a high diversity of characteristics. From the observation results, a similarity analysis was described and carried out using the NTSYS 2.02 program. The results showed that 10 cultivars of local rice plants with a similarity coefficient of 0.29-0.92 or 29-92% were obtained. 2 genotypes were obtained that were grouped close together, namely C4 and C5 at a coefficient of 0.71. Judging from the coefficient of similarity of local rice plants in the location are close relatives.

Abstract

Economic potential and growing public interest in the grapes have led to the plant having high prospects for cultivation and development in other parts of Indonesia. The aim of this research is to produce quality seedlings through network culture techniques. The method of providing grape seed is relatively fast with the amount of seed produced quite a lot that is through the technique of network culture. The research was conducted from March to May 2023 at the Laboratory of Physiology and Culture of Plant Networks, Faculty of Mathematics and Natural Sciences, University of North Sumatra, Field, North Sumatera. Parameters observed in Vitis vinifera plant tissue culture practices with a combination of IAA and BAP treatment on MS media are growth time, growth percentage and contamination percentages. Data from the study was analyzed using Analysis Of Variance (ANNOVA). If the treatment gives a significant different effect then proceed with the Duncan New Multiple Range Test (DNMRT) at the level of 5% (P 0.05) on the treatment factor.Treatment I1 has the fastest increasing power output with an average growth time of 9 a. Further testing results show that the treatment of IAA and BAP hormones in different media is significantly higher than the control. The results of the study showed that the highest percentage of explanation growth (100%), although it took a relatively longer time to form the calus and shoots.

Abstract

The research aims to determine the increase in students' cognitive learning outcomes through a demonstration of the use of Al2(SO4)3 for dyeing fabric on colloidal materials. The method in this research is one group design, namely research is only carried out in one class. Data collection techniques used field observation, interviews, pretest and posttest as well as response questionnaires. The results of this research showed that the average pretest score before treatment was 53.68%, while after treatment there was an increase with an average posttest score of 81.04% with a pretest and posttest N-Gain index of 0.5 in the medium category and a percentage of 58%. Based on the results of this research, the application of Al2(SO4)3 for effective fabric coloring can increase students' cognitive learning outcomes.

Abstract

The Realistic Mathematics Education approach emphasizes understanding concepts through the context of everyday life, while conventional methods can provide a solid foundation in mathematical concepts. Therefore, teachers use conventional and realistic methods in teaching mathematics to improve student learning outcomes. Comparative analysis is the research method used in this study. The purpose of the Comparative Study between Realistic Mathematics Learning and Conventional Methods in Improving Students' Understanding of Mathematics Concepts is to compare how well the two approaches, realistic mathematics learning and conventional methods, in improving students' understanding of mathematics concepts. This research aims to find out whether the conventional approach or the Realistic Mathematics learning method is more effective in helping students understand mathematical concepts. It is expected that the information or data obtained from this research can provide an overview of learning strategies that are more effective in improving students' understanding of mathematical concepts. The final result of this research is expected to provide important data related to learning strategies that are more feasible to help students in understanding numerical ideas. The results of this study will have a significant impact on the development of more efficient methods for teaching mathematics in the classroom.

Abstract

The application of probing and prompting techniques is the application of science and technology by conducting investigations or examinations by relating questions in the form of cause and effect aimed at encouraging or guiding the achievement of satisfactory learning outcomes. The application of probing and prompting techniques as a source of independent learning because it requires the involvement of students in exploring and guiding learning. The application of probing and prompting techniques is expected to make students more interactive in learning. So that student curiosity can increase in accordance with the expected learning objectives. This research was motivated because probing and prompting techniques had never been applied at SMA Negeri 4 Padangsidimpuan. This study aims to determine whether there is an influence of the application of probing and prompting techniques on students' curiosity and learning outcomes on oxidation reduction reaction material in class X MIA SMA Negeri 4 Padangsidimpuan. The data on the curiosity test of students in the experimental class was with an average of 49.37 and in the control class was with an average of 49.17, so students' curiosity was higher in the experimental class. Then classes that used Probing and Promting techniques obtained an average learning outcome test of 36.47 to 79, so there was an increase.
