Abstract

This study aims to analyze the relationship between metacognition ability and understanding of mathematical concepts of grade VII students. This study used a qualitative descriptive method, with three students selected based on their level of metacognition ability (high, medium, low). Data were collected through written tests, in-depth interviews, and observations. The analysis is carried out based on indicators of understanding mathematical concepts, such as restating concepts, classifying objects, developing concept terms, and selecting and implementing appropriate procedures. The results of the study show that students with high metacognition skills are able to understand concepts in depth, consistently, and effectively in practical application. Students with moderate metacognition skills show quite good understanding but are less consistent. Meanwhile, students with low metacognition skills experience significant difficulties in understanding and applying mathematical concepts. These findings emphasize the importance of metacognition-based learning strategies to improve students' understanding of mathematical concepts.

Abstract

Mathematics is known as a science that always uses concepts and calculations. Under the pretext that mathematics is just calculations, of course, there is a possibility that there will be a response about mathematics that has nothing to do with the story in the Bible. In fact, based on previous research, it has been stated that one of the two qualities of the Bible is Clear and Sufficient. Considering these two properties, this study aims to prove that the Calculation of the Volume of Noah's Ark using Integral can Reveal the Clarity and Adequacy of the Bible. The research method used is a descriptive research method based on biblical statements that are calculated using integrals. The final result of this study states that the Calculation of the Volume of Noah's Ark using Integral can indeed reveal the Clarity and Sufficiency of the Bible as a form of immeasurable measurement. The meaning is: 1) The clarity of the Bible regarding the Volume of Noah's Ark using Integral can be interpreted and understood with the help of the Holy Spirit. 2) The sufficiency of the Bible regarding the Volume of Noah's Ark using Integral can be interpreted and used as a guideline for every believer's life.

Abstract

The waste problem is one of the serious problems faced by every city in Indonesia, including Bengkulu City. To overcome the problem of waste production which continues to increase every day, the government's role is needed in efforts to transport waste with various facilities and support from the surrounding community. One effort to solve the problem of waste piling up in Temporary Disposal Sites (TPS) is to schedule effective transportation to Final Disposal Sites (TPA). To do the scheduling, one possible approach is a mathematical approach. The purpose of this research is to build a Vehicle Routing Problem (VRP) model using Ant Colony Optimization (ACO), and determine the solution of this model to determine the optimal solution to the problem of transporting waste from all TPS to TPA. This research involved 29 TPS in Bengkulu City. This model is solved using Python 2.7 programming language and PuLP modeller and CPLEX Solver. With 2000 iterations, solutions were found in a relatively short time, which is less than 10 minutes. There are 6 garbage transportation routes in Bengkulu City which are considered as a VRP problem by using ACO which can transport garbage and considering the capacity of garbage trucks. From this route, a total distance of 128 km is obtained.

Abstract

Motivation and physics learning outcomes among students remain low. One approach to improving both aspects is the use of contextual teaching assisted by PhET. This study aims to determine whether and to what extent the application of the contextual teaching and learning model assisted by PhET influences students' motivation and physics learning outcomes. This research employs a quantitative quasi-experimental method and was conducted at SMA Negeri 71 Jakarta, with samples selected through purposive sampling. The instruments used include a questionnaire to measure learning motivation and a test to assess learning outcomes on Ohm's law, resistor circuits, and Kirchhoff's first law. Hypothesis testing using an independent sample t-test resulted in a significance value of 0.000 < 0.05, indicating a significant effect of PhET-assisted contextual learning on motivation and learning outcomes. The effect size analysis showed values of 0.289 for motivation and 0.655 for learning outcomes, categorized as moderate and high, respectively. Thus, it can be concluded that PhET-assisted contextual learning has a moderate impact on motivation and a strong influence on learning outcomes.

Abstract

This study aims to analyze the effectiveness of mathematics learning with an open-ended approach in improving the learning independence of Vocational High School (SMK) students. This study uses a quasi-experimental method with a pretest-posttest control group design involving two groups of class XI Computer Network Engineering students (TKJ 1 and TKJ 2). The sample used was 72 students, which were divided into an experimental group and a control group. Data on student learning independence were collected through a learning independence questionnaire consisting of 36 statements that were analyzed using statistical tests with the help of the SPSS version 30 program. The results showed that the experimental group using an open-ended approach experienced a more significant increase in learning independence compared to the control group. This finding indicates that the open-ended approach is effective in improving student learning independence, which is very important in preparing them to face the dynamic world of work. However, the level of student learning independence is still in the low category, which indicates the need for the implementation of advanced strategies to further maximize the potential for student independent learning in the long term.

Abstract

This study aims to analyze the fixed carbon content and combustion rate of briquettes made from banana peel waste as a renewable energy alternative. The experimental method was used, involving key stages such as material preparation, carbonization process, briquette molding, and testing of fixed carbon content and combustion rate. The results showed that the fixed carbon content of the produced briquettes reached 87%, indicating good combustion quality and high energy storage capacity. Additionally, the combustion rate of the briquettes varied, with Sample A having a combustion rate of 0.017 grams/s and Sample B at 0.014 grams/s. This difference suggests that Sample B has a longer combustion duration. Thus, banana peel briquettes have the potential to be an efficient and environmentally friendly alternative fuel. Further research is needed to optimize the production process and enhance briquette efficiency.
