This research involves 38 JUNIOR students with math skills vary, 12 students with high math ability, 18 students with the capabilities of the math medium, and 8 students with a mathematical ability is low. The entire students are asked to work on the problem-solving tests individually, with its main focus are as follows: (1) students were asked to write down what was known to be reserved; (2) write back what is asked the question; (3) write the problem resolution plan; (4) to resolve the issue in accordance with the plans that have been written; (5) try the other possible alternative in resolving problems; (6) rechecking problem resolution. The findings show that students answer math problems solving has diversity which is categorized into four categories: no changes mean, a variability of blind, orthodoxy, and creativity. Students in the creative categories are students who can solve problems by integrating CT and DT by using two models: the CDM and DCM. Students in this category can have opportunities to create and explore the variability.

Fuzzy graph is a graph consisting of pairs of vertices and edges that have a membership degree that contains a closed interval of real numbers on each edge and vertex. A fuzzy graph is said to be a strong fuzzy graph if the membership degree of edge with the minimum membership degree of vertex and the same membership degree of vertex for each edge with . This paper explains the properties of fuzzy graph isomorphism including weak isomorphism, co-weak isomorphism, and isomorphism in strong fuzzy graphs.

Based on observation results, students' low level of creative thinking in mathematics lessons is influenced by the use of inappropriate methods, so teachers are required to innovate using fun learning methods. One method that makes students interested in learning mathematics is a realistic mathematics learning method. This research aims to improve students' creative thinking abilities in positive whole number material using a Realistic Mathematics Learning approach. Based on the research results, it was found that students' creative thinking increased from 25.94% to 66.7% in the first cycle, and 80.96% in the second cycle. After conducting research on the Realistic Mathematics Education (RME) approach to improve students' creative thinking, it can be seen from the results of initial observations that there has been quite a significant increase until the second cycle process.

This research aims to describe the analysis of students' creative thinking in posing SPLDV problems in terms of students with high abilities and low abilities. This research is a qualitative descriptive study. The material used is Systems of Linear Equations in Two Variables (SPLDV). SPLDV are two linear equations that have solutions in the form of ordered pairs which can be represented by x, y. The results of the research are that students with high abilities in asking SPLDV problems can be included in the good category. Students with medium low ability in asking SPLDV problems are still in the sufficient category. Low ability students HY are only able to meet the indicators of creative thinking fluency. In planning and implementing SPLDV problem submissions, it is seen from cognitive ability, namely high ability and low ability are still categorized as lacking.

This research aims to describe the profile of students with high, medium and low mathematical abilities in solving word problems on flat shapes. This study used descriptive qualitative method. Supporting instruments include mathematical ability tests, problem solving tests and interview guides. The data obtained from this research are the results of students' mathematical ability tests and the results of mathematical problem solving tests in the form of story questions, both written tests and interviews. The results of this research are that students with high mathematical abilities in understanding problems, planning solutions, carrying out solutions and re-examining problem solving are included in the good category. Students with moderate abilities in understanding problems are quite good, in planning solutions they are quite good, in carrying out problem solving plans they are in the poor category and in re-examining solutions they are not good enough. Students with low mathematical abilities in understanding problems are in the fairly good category, in planning solutions are quite good, while in carrying out and re-examining problem solving they are in the not so good category.

Mathematical modeling is the process of deducing a mathematical model of a phenomenon based on the assumptions used. The purpose of a mathematical model is to make decisions based on real situations by analyzing the model. This research aims to obtain a mathematical model of income for KUD Karya Bhakti Pamekasan, to determine the most dominant variables influencing income and to determine the perception of the Karya Bhakti village community regarding income and progress of KUD in the area. The method used in this research is a quantitative method. Data collection techniques through literature study. Data analysis uses linear regression analysis to obtain a mathematical model, namely Y=228961 935 - 0.197x e. The constant is 228961935, which means that if income (Y) is non-existent or zero (zero), then the SHU (Y) in the cooperative will decrease by IDR 289,61,935. Meanwhile, the b value (regression coefficient) shows a negative value of 0.197. A value of 0.197 means that if income is zero then the SHU remains the same and every additional 1 sale reduces the SHU by 0.197.

This research aimed to reveal various reasons that encourage teachers to use outdoor learning, the implementation of outdoor learning in schools, obstacles, and the positive impact of implementing outdoor learning at SDN 2 Tajinan. Researchers employed a descriptive qualitative approach, where data collection was carried out through interviews, observation, and documentation. The research results showed that the reasons teachers use outdoor learning include increasing learning engagement, providing authentic learning experiences, honing skills, and introducing students to the environment. Apart from that, outdoor learning is carried out to connect theory and practice in everyday life, create contextual learning, and develop social skills, problem-solving, and students' curiosity. Outdoor learning is carried out by inviting students to plant plants in the school environment, visiting the Arhanud Education Center in Batu City, and inviting students to get to know the environment around the school. The obstacles faced by teachers are difficulties in conditioning students due to the large number of students and the weather and natural conditions. Apart from that, implementing outdoor learning requires more thorough preparation and tends to take longer than conventional learning. The positive impacts that arise include being able to increase student enthusiasm and involvement in learning, making learning more lively, and increasing students' social-emotional aspects, responsibility, and concern for the environment.
