Abstract

The low student learning outcomes are caused by a lack of ability to understand concepts and many students are not serious about working on questions, so that learning is not optimal and effective. Therefore, the general aim of this research is to describe the influence of TGT type cooperative learning based on badeglar media on the conceptual understanding of class X students at Adi Luhur Vocational School for the 2023/2024 academic year. The method in this research uses a pre-experimental method, namely comparing the results of the pretest and posttest with the research population being all class X students at Adi Luhur Vocational School and the sample used in this research is the population itself. Data was collected using test techniques with test sheet research instruments. The data is processed according to parametric statistical calculations. The results of this research prove that the use of TGT type cooperative learning based on counting funnel media has a positive effect on student learning outcomes. The average percentage of student learning outcomes using t-test calculations where tcount is greater than ttable, namely 3.277 > 1.740. So it can be concluded that H0 is rejected and H1 is accepted, in other words there is a significant difference between the pretest and posttest

Abstract

Advances in science and technology are faced with a number of challenges, one of which is preserving the environment which is faced with the use of synthetic materials. Synthetic materials are basically materials that cannot be decomposed naturally and pollute the environment. Therefore, a number of research and developments have been carried out in utilizing more environmentally friendly materials through the manufacture of biocomposites. However, the use of biocomposites has not been able to replace the use of synthetic materials as a whole, due to the weak bonding of the fiber-matrix interface (adhesion between fiber and matrix) in biocomposites. One effort that can be made to increase fiber-matrix interfacial bonding in biocomposites is through modification of natural fibers using NaOH. A number of studies have been carried out using NaOH to modify the fiber-matrix surface. The results obtained through a number of studies state that each natural fiber has a different response to NaOH concentration, so that each natural fiber requires a certain concentration to increase the bond between the fiber-matrix interface in biocomposites.

Abstract

This research aims to explain a review of the relationship between Self-efficacy and the ability to understand mathematical concepts, and how to develop and measure student Self-efficacy. In this research, the Systematic Literature research method was used which aims to obtain data from relevant research. With research sources coming from Google Scholar, Researchgate, Scopus, Syntax, and DOAJ. In this research, 17 reference sources were collected to obtain data and information. Information collected regarding differences in mathematical concept abilities in students' Self-Efficacy criteria, Development of Self-Efficacy in students in mathematics learning, Impact of students' Self-Efficacy on their ability to understand mathematical concepts, Measurement techniques (Indicators) of Self-Efficacy Efficacy of students' understanding of mathematical concepts. From the data collected, it was found that the technique that is often used is the Bandura technique. To develop self-efficacy in mathematics learning, you can focus on learning objectives, adding learning models, as well as 4 triggers, including: Mastery of experience, represented experience, social persuasion, and physical and affective conditions. In activating or applying these abilities, self-efficacy can have a positive impact on learning for students through external and internal learning activities of individual students. And self-efficacy is also useful in maintaining students' resilience in answering difficult questions, as well as understanding the concepts more deeply.

Abstract

This research aims to evaluate the effectiveness of the Missouri Mathematics Project (MMP) Learning Model in improving mathematics learning outcomes for junior high school students. This study employs a comparative approach, comparing mathematics learning outcomes between students taught using MMP and those taught using conventional teaching models. Data were collected through hypothesis testing of mathematics learning outcomes for both groups. The data analysis results indicate a significant difference in mathematics learning outcomes between the two groups, with a significance value (sig.) smaller than the commonly used significance level. These findings suggest that the implementation of MMP effectively improves mathematics learning outcomes for junior high school students. The practical implications of these findings are discussed in the context of developing more effective and inclusive mathematics teaching strategies.

Abstract

The destruction of the incesce customary forest in Pandumaan village and the conflict over customary land with PT Toba Pulp Lestari (TPL) have damaged the preservation of the incesce customary forest. This condition really needs attention and restoration. Frankincense trees are continuously cut down by the company. Frankincense trees and other natural wood in the forest are cleared using a clear-cutting system and the logging areas are immediately planted by PT.TPL. The research method in this study uses qualitative descriptive analysis research methods. The author will conduct a special investigation regarding ecological restoration proposed by Van Wearen. Qualitative research in data collection is carried out using primary data sources, and data collection techniques will look for literature reviews, books, news and journals by collecting data from various literature. Restoring customary forests is also healing God's creation which has been damaged by humans. Understanding of ecological restoration as a basis for restoring the traditional incesce forest in Pandumaan village. The traditional forest of Pandumaan Village is a beautiful creation of God that should be protected and preserved.

Abstract

The low interest in reading among elementary school (SD) students poses a significant challenge in the context of primary education. This article identifies various factors that contribute to the low interest in reading among students, including lack of access to engaging reading materials, insufficient support from parents, lack of motivation or intrapersonal interest, uninteresting curriculum and teaching methods, influence of electronic media, socio-economic conditions, lack of reading role models, and difficulties in reading. The analysis yields recommendations that encompass improving access to engaging reading materials, encouraging parental support, fostering student motivation and intrapersonal interest, and developing engaging curriculum and teaching methods. Through a holistic and sustainable approach, it is hoped that these recommendations can help address the challenges of low reading interest among elementary school students and enhance the quality of literacy learning at the primary level.
