ANALYSIS OF THE DIFFICULTIES OF GRADE VII H STUDENTS OF SMP NEGERI 6 PALU IN SOLVING SET STORY PROBLEMS IN TERMS OF LEARNING STYLE

,


INTRODUCTION
Mathematics is a very important subject to learn.As stated by Widiantara (2014) that mathematics is one of the subjects studied from elementary school level to high school level and also studied in universities.This happens because mathematics is an activity of human life, meaning that every human activity always uses mathematics.So it is important that everyone knows the basic material about mathematics so that they can apply and solve problems related to everyday life.In line with this Soedjadi (Ratnamutia and Pujiastuti, 2020) suggests that the general purpose of mathematics is to prepare students to be able to use concepts from mathematics in daily activities or life.
Mathematics plays an important role in learning, so it is expected that students master mathematics subjects, but in reality until now the ability and learning achievement of students in mathematics subjects is still relatively low.It is evident from the 2018 PISA (Programme for International Student Assessment) results conducted by the OECD (Organization for Economic Cooperation and Development) that Indonesia is ranked 73 out of 78 countries with a score of 379 in mathematics and with an average score of 489.There are several things that cause Indonesian students' math achievement to be very low, one of which is the difficulty experienced by students in learning mathematics (Ratnamutia and Pujiastuti, 2020).Abdurrahman (Dewi et al, 2020) stated that of the various fields of study taught at school, mathematics is the field of study that is considered the most difficult for students to understand, especially for students who have difficulty learning mathematics.
Learning difficulty is an obstacle that is often faced by students.Mulyadi (Dewi, et al 2020) suggests that learning difficulties can be interpreted as a condition in a learning process characterized by certain obstacles to achieving learning outcomes.One of the difficulties experienced by students in solving math problems if the problem is presented in the form of a story.This can be seen based on the mistakes made by students in solving math problems.
solve the story problems given.This is in line with research conducted by Muntaha, et al (2020) that students' difficulties in solving story problems are the difficulty of students understanding the story, determining the existing quantities and their relationships so that a mathematical model is obtained and solving the mathematical model mathematically.
According to Muncarno (Sudirman, et al. 2018)  Mathematics story problems are presented in the form of a story or a series of simple and meaningful sentences (Widyaningrum, 2016).Mathematics story problems provide a real picture in everyday problems for students and to train students' ability to solve mathematical problems in everyday life.(Nurajizah & Fitriani, 2020).Many things related to mathematics are in the surrounding environment in everyday life, for example, when paying for groceries purchased at a market or supermarket, exchanging money, determining time, and many more (Ratnamutia and Pujiastuti, 2020).
According to Syah (Fatmawati, 2019) several factors will occur if the completeness of student learning outcomes is low, especially internal factors and external factors.Factors that are in students are internal factors that also affect learning outcomes.Some of the internal factors that are still not seen by teachers are learning styles.So it can be said that learning styles can affect student learning difficulties, this is supported by Dewi and Bahar (2021) that there are many factors that influence students' difficulty in solving math problems, one of which is influenced by the habits of the mathematics teaching and learning process carried out in class, one of which is the student's own learning style.
According to Rosyida (2016) learning style is a combination of how a person absorbs and then organizes and processes information.In line with the opinion of Rosyida (2016), learning style according to Fleming and Mills (Wassahua, 2016) is the tendency of students to adapt a certain way to their learning as a form of their obligation to get a learning approach that suits the demands of learning in class or school and the demands of the subject.
DePorter & Hernacki (2007) state that there are three learning styles that a person has, namely visual, auditorial and kinesthetic learning styles.Basically, every individual has a learning style but not all of them develop in a balanced manner but some dominate their learning style.GA also had difficulty in solving the problem.In the difficulty of solving verbal problems, GA made mistakes in translating the problem into mathematical form.GA also could not determine the data used, and had difficulty checking the answers obtained.
Based on the explanation above, it can be concluded that subjects with an auditorial learning style fulfill all indicators of difficulty, namely difficulty learning concepts, difficulty applying principles and difficulty solving verbal problems.The results of this study are in line with (Nuriza, et al 2020) where the difficulty that tends to be experienced by students with an auditorial learning style is making mathematical models so that in the end there are incorrect calculations.

Based on the picture above, on the difficulty of learning the concept, GK subject can translate the form/illustration of the problem, but the subject is hesitant in using memorization or set notation.GK cannot use a formula that matches the condition of the problem.So in this case it can be concluded that GK has difficulty in learning concepts.In the difficulty of applying principles, GK made mistakes in calculation activities.This happened because GK did not know the formula, causing errors in using the data that should be used.
So in this case it can be concluded that GK has difficulty in applying principles.In the difficulty of solving verbal problems, GK could translate the problem into mathematical form but made mistakes in determining the data used, GK did not recheck his answers so in this case it can be concluded that GK had difficulty in solving verbal problems.
Based on the explanation above, it can be concluded that subjects with kinesthetic learning styles fulfill all indicators of difficulty, namely difficulty learning concepts, difficulty applying principles and difficulty solving verbal problems.However, in the difficulty of applying principles, GK made mistakes in calculation activities.This happened because GK did not know the formula and made mistakes in using the data used.However, GK can complete the calculation, so in this case it can be concluded that GK has difficulty in applying principles.
The results of this study are in line with Widyanimgrum, (2016) where the most dominant error made by students with kinesthetic learning styles is language interpretation errors, namely students have not been able to interpret problems into mathematical language.
Meanwhile, as a result of this, students also make technical errors, conceptual errors, and errors in the use of data.
From the data above, it shows that students' abilities in solving problems, both GV, GA, GK, have different abilities, one of the factors that influence the ability to solve problems is learning style.Likewise, the results of research conducted by Johson and Miller (Sari, 2021) where a person's learning style can be determined by the learning experience and the field of study studied.Where students in the disciplines of physics, mathematics, chemistry are more likely to have a visual learning style.In Susanti's research, et al (2020)  formulas that are in accordance with the conditions of the problem, namely the formula for the combination and difference of three sets.In difficulty applying principles, students make mistakes in calculation activities when solving problems.In the difficulty of solving verbal problems, students make mistakes in translating the problem into mathematical form.Students also cannot determine the data used, and do not check the answers obtained.

Students with kinesthetic learning styles experience all indicators of difficulty, namely difficulty learning concepts, difficulty applying principles and difficulty solving verbal problems.In difficulties in learning concepts, students hesitate in using memorization or set notation.Students cannot use formulas that match the conditions of the problem, namely the formula for the combination and difference of three sets.In difficulties in applying principles, students make mistakes in calculation activities.This happens because students do not know the formula and make mistakes in using the data used.In the difficulty of solving verbal problems, students make mistakes in determining the data used, students do not check their answers again.
that students have difficulty working on story problems because students are less careful in reading and understanding sentence by sentence and about what is known in the problem and what is asked, and how to solve the problem correctly.Based on the results of interviews that researchers have conducted with one of the teachers of SMP Negeri 6 Palu, researchers received information that most of the seventh grade students are weak and have difficulty working on story problems.Students have difficulty working on story problems because they find it difficult to understand the problem, one of the materials that are difficult for seventh grade students to understand is set material. figure.

stated that the learning difficulties experienced by students vary based on their learning style.Students with auditory learning styles have difficulty in receiving material with low proportions and explanations or discussions.Students with kinesthetic learning styles have difficulty in understanding writing or images and the lack of practice problems given.While students with a visual learning style have difficulty in understanding material with a low level of visuality.Based on the results of research and discussion, the conclusion is obtained related to the analysis of the difficulties of students of class VII H SMPN 6 Palu on the problem of set stories in terms of learning styles, namely: 1. Students with visual learning styles experience two indicators of difficulty, namely difficulty learning concepts and difficulty applying principles.For difficulties in learning concepts, students cannot use formulas that are in accordance with the conditions of the problem, namely the formula for the combination and difference of three sets.As for the difficulty of applying principles, students make mistakes in calculation activities and do not solve the problem.students are only able to master one indicator of difficulty, namely difficulty solving verbal problems.2. Students with auditorial learning styles experience all indicators of difficulty, namely difficulty learning concepts, difficulty applying principles and difficulty solving verbal problems.In the difficulty of learning concepts, students cannot translate the form of the problem, do not know what is known from the problem, students also cannot use
