Abstract

The purpose of this study is to describe the analysis of farmers' economic concepts, especially the wage system of land hoe labourers. The low wage value of land hoe labourers is a deep concern considering the amount of energy expended by farmers in spending their potential throughout the day on the farm. In this context, the use of mathematical ethnoscience in human life is something that may not be clearly observed. This study becomes very interesting, when the awareness of local power to apply mathematical concepts is realised as an amplifier of human needs in solving their life problems. Life's problems are increasingly complicated in the construction of inevitable needs. This research method is a qualitative research method with a descriptive approach. This research operationally examines various sources of literature relevant to the above research context. This research is qualitative descriptive research using the content analysis method to obtain the results that in the use of hoes there are several physics concepts about mechanics including the concepts of force, rotational dynamics, work and energy. Based on the results of data analysis and discussion, it can be concluded that there are several physics concepts in the use of hoes in cultivating the soil starting from the mechanical advantages of using a hoe, the moment of force when swinging a hoe, the compressive force exerted by the hoe, the lifting force when lifting the soil, the pulling force when pulling the soil, and the effort and energy expended during hoeing activities.

Based on this background, this research aims to enhance students' creativity in addressing energy issues. The research method employed is a quantitative research method with a Pretest-Posttest Nonequivalent Control Group Design, which is a form of Quasi Experimental Design. The subjects in this study are twelfth-grade science students (XII MIPA) selected through purposive sampling and divided into two groups, namely the control group and the experimental group. The control group uses a project-based learning model, while the experimental group uses project-based learning based on the engineering design process. The number of samples for the experimental group is 33 students, and for the control group, it is 34 students, making a total of 67 research subjects. The creative thinking skills of students are measured using a descriptive test that includes indicators of creative thinking skills, while student creativity in their products is measured using an assessment sheet for creative products based on presentations and testing of creative products carried out at the end of the learning process. The data analysis results show that there is an improvement in students' creative thinking skills, as indicated by the average N-Gain achievement of 53.3%, falling into the moderate category. Additionally, the creativity of student products in all creative product indicators is rated as highly creative, with an average score of 89. The Mann Whitney U Test results indicate a significant difference in the improvement of creative thinking skills and student creativity in their products
