Abstract This study aims to improve student achievement in learning chemistry in class X MIA4 at SMA Negeri 1 Palu by applying the Jigsaw Cooperative Learning Model. The classroom action research (CAR) problem can be formulated as follows: Is the Jigsaw Cooperative Learning Model application able to improve student achievement in learning chemistry in class X MIA4 SMAN 1 Palu? CAR is carried out with the following stages to answer the problem: 1. planning, 2. observation, and 4. evaluation and reflection. The study results can be explained as follows several fundamental aspects of learning were successfully improved by applying the Jigsaw cooperative learning model. Such as student activity in collaboration and in completing worksheets independently, actively asking and answering questions, and making students feel happy and enthusiastic. Likewise, the average evaluation of each cycle showed that the percentage completeness increased. In cycle one, action one was 73. 8%, action two 85. 5%, and activity three 92. 9% increased in cycle two, the average from three actions was 98. It can be concluded that the application of the Jigsaw cooperative learning model can improve student achievement in class X MIA4 SMA Negeri 1. Keywords: Cooperative learning, jigsaw, learning achievement, chemistry learning of daily tests for class X shows that students who have not completed individually are 45. The formative test results indicate that student achievement is still below the average class success, with a percentage of at least greater than 75%. shows that student achievement in chemistry subjects still needs to be improved. Efforts to improve student achievement in chemistry subjects need to be taken seriously by chemistry teachers because chemistry teachers are the spearhead of implementing learning in the Therefore, improving student learning achievement must be done by chemistry teachers by making changes, innovations, and new creativity in chemistry learning (Manurung, 2. So far, it has been objectively acknowledged that chemistry learning is too dependent on the lecture method or various lectures. Sometimes the teacher also improves the question and answer practice and However, the results are still less So chemistry teachers need to apply a method or learning model that can optimize all learning resources such as. teachers, students themselves, and fellow students. Teachers' pedagogical strategies will improve students' skills and four learning dimensions: knowledge, process, understanding, and product (Tabiolo & Rogayan. Introduction The quality of education in Indonesia has It is due to the improvement of the One of the subject matter taught in high school education units is chemistry. The burden carried by the school, in this case, the teacher, is weighty because it is the teacher who is at the forefront in shaping the students' personalities. Thus the education system in the future needs to be developed so that they are more responsive to the demands of society and the challenges the world of work will face. The availability of learning tools is one of the factors that can support the learning process to run well and improve the quality of education. previously stated, this is in agreement with Ayuningtyas et al. that learning tools provide convenience and can assist teachers in preparing and carrying out teaching and learning activities in the This toolkit offers several strategies to encourage students to use different learning styles. Thus, with careful planning, the needs of all students can be met in a Science class. The teaching pattern described above is one of the causes of the low academic achievement in chemistry subjects for graduates of SMAN 1 Palu.

Sitti Rahmawati et al. One of the cooperative learning-based learning models considered to improve student achievement in chemistry subjects is the jigsaw model (Kartika et al. , 2. The jigsaw model provides students opportunities to find the knowledge that is their task and jointly, in groups, develop that understanding (Halimah & Sukmayadi, 2. The knowledge found by themselves through the jigsaw model will eventually be embedded in students' minds . tudents do not easily forget because they found it themselve. In addition, this jigsaw model allows students to do a kind of shearing between groups by forming expert groups (Halimah & Sukmayadi, 2019. Wang, 2. that through this jigsaw model, chemistry learning takes place dynamically and interestingly because of the variations in the origin group and the expert If in learning chemistry with various lecture and lecture methods, students gain knowledge only through the teacher, then through the cooperative learning jigsaw model, each student can gain knowledge from 4 . sources simultaneously. From the students themselves personally. Other students in the group, 3. other groups through groups or expert teams, and 4. From the teacher as a learning facilitator Research on the application of cooperative learning jigsaw models in learning has been carried out, including Applications of jigsaw collaborative learning in science learning and basic technology: changes in physics and chemistry. The results showed that jigsaw cooperative learning resulted in a significantly better mastery of scientific concepts related to physical and chemical changes than traditional learning. The students who took the lesson had a lower proportion of misconceptions. Jigsaw cooperative learning is an effective teaching technique that can increase students' motivation, learning achievement, self-confidence, and willingness in science and technology lessons (Tarhan et al. , 2. Another research is on the effect of the jigsaw cooperative learning model and confirmatory laboratory method on the achievement of prospective physics teachers in science teaching and learning practice courses. Another research is about the effect of jigsaw cooperative learning and confirmatory laboratory methods on the achievement of prospective physics This paper aimed to describe the chemistry learning achievement of class X MIA4 students at SMA Negeri 1 Palu by applying the Jigsaw Cooperative Learning Model. ccording to the lesson schedule at SMA Negeri I Pal. in a predetermined class, namely X MIA4. The duration of action is six weeks or six meetings divided into two cyclesAione cycle of three steps, where each activity is allocated 2 hours of lessons. So the total number of lesson hours used in this classroom action research (CAR) was 12 hours of Factors studied Student factors: Seeing student achievement results after following the action . in chemistry subjects. In addition, students' responses were also observed during KBM with jigsaw actions. Student responses that need to be followed such as perseverance, seriousness, cooperation in groups, a collaboration between groups . eam of expert. , the ability to ask and answer questions, and respect for other groups Teacher factor: Seeing how the teacher designs learning with the jigsaw model includes identifying the materials and tools used, learning tools, observation and evaluation tools, and observing the implementation of actions carefully and in-depth. Activity procedures Planning There are three stages in planning this CAR: The first stage is compiling learning tools in the form of learning scenarios and teaching plans, determining the nine sub-subjects . that are the content of the action. The determination of this material is adjusted to the curriculum and learning tools, especially study material analysis, preparing learning materials and tools, and organizing relevant learning media. The second stage is to make indicators for the design of group formation based on gender, religion, and of course, the level of achievement/academic ability of students. At this stage, a plan for changing the composition of group members has also been prepared nine times . to avoid group saturation The third stage is making various instruments of action in the form of devices for observing teacher activities and student activities in KBM with jigsaw actions, making evaluation instruments that are tailored to specific learning objectives as contained in learning tools, especially teaching plans Implementation The action was carried out nine times in three The target of the action is students, the teacher's giver of action, and the type of action is the cooperative learning jigsaw model. As an action giver, the teacher has activities to carry out these actions divided into three stages: the initial stage . pening/introductio. , the core activity stage, and the final or closing stage. Similarly, student activities are divided into three phases . arly, core, and fina. Teacher activities in the early stages include. Delivering greetings, attending attendance. Methods Research settings This research was conducted at SMA Negeri I Palu. Central Sulawesi Province. The research subjects were students of class X MIA 4, with 42 students consisting of 18 males and 24females. The action was carried out during chemistry class hours Volume, 11. No. 1, 2022, 39-45 Jurnal Akademika Kimia Data collection techniques conveying the title of the material and the importance of the material, stating the learning objectives, generating initial knowledge, forming groups, explaining student assignments in groups, and motivating students and sharing the required At the same time, student activities in the early stages include responding to greetings, responding to attendance, paying attention to goals, listening to material explanations, sitting in groups, taking notes and understanding group assignments, and receiving worksheets/materials given by the At the core activity stage, the teacher carries out several activities or actions such as: asking students to understand the worksheet, asking students to do assignments according to the worksheet, helping and guiding students to work together in groups, forming expert groups/teams, asking the expert team to explain the results of their discussions to the The initial group set the percentage course and set the responders in turn. At the core activity stage, the student activities include understanding worksheets, doing assignments according to worksheets, conducting cooperatives, actively discussing in expert teams, socializing the results of expert team discussions, making presentations, and providing responses to other groups. Furthermore, the teacher's activities at the final stage are stated, namely: responding to group work results and presentations, concluding, evaluating formative tests, and ending learning. At the same time, the student activities at the final stage are observing the teacher's conclusions, making independent summaries, completing formative test questions, and responding to closing greetings from the teacher. Observation Observations were made before and during the implementation of the action. Before, the practical action was in the form of completeness of teacher learning, including worksheets and media. when the action is carried out, what is observed is the teacher's activities in carrying out measures starting from the initial, core, and final stages. Students' responses were also monitored while receiving actions, especially collaboration between students and expert Reflection Reflection is intended to identify the strengths and weaknesses of the actions that have been taken. The sources of information for reflection are the results of observations of teacher and student activities and the evaluation results of formative A good assessment of the previous action is maintained in the following step. While specific weaknesses are discussed together, look for the best way to improve these weaknesses. Thus, the researcher makes this reflection stage a medium for revision of action. Reflection is getting more mature every time you finish one cycle Source of data: Students and teachers Types of data: Two types of data are the research target: Qualitative data, obtained from the observations of teacher and student activities in each action in the form of an observation sheet and presented in the form of a percentage. Quantitative data were obtained from the evaluation results given at the end of each action . ormative test-post-tes. , and the instrument used was a learning outcome Data analysis techniques In classroom action research, the increase in student achievement due to the action is the most expected aspect. Therefore, the analysis used is closely related to the study of student achievements, such as analysis of absorption, learning completeness, and average scores. The formula used is as follows: Individual absorption % ycnycuyccycnycycnyccycycayco ycaycaycycuycycycnycuycu = ycycaycuycyce ycuycaycycaycnycuyceycc ycayc ycyycaycycycnycaycnycyycaycuyc ycyc ycu 100% max ycycaycuycyce ycycyceycycycnycuycu Complete learning individually.

The constructivism approach is considered successful in increasing student learning achievement if each action produces a minimum of 60% individual absorption . ndividual master. and is said to have completed classical learning. if 85% or more students have completed learning Results and Discussion The data obtained are presented in two categories, namely the results of observations of teacher activities (Table . and student activities (Table . Based on Table 1, it can be seen that the Sitti Rahmawati et al. development of teacher activities in each cycle through the application of the jigsaw cooperative learning model is increasing. It can not be separated from the improvement efforts made by the teacher based on the suggestions and reflections of each Of course, the teacher's activities in each process can affect student activities in participating in learning (Widayati, 2. The results of observing student activities are presented based on Table 2. Table 1.

After describing the data for cycles one and two accompanied by details of strengths and weaknesses, it can be seen that the results of the research both concerning teacher and student activities showed an excellent tendency to increase student achievement. In other words, student learning outcomes in chemistry subjects using the jigsaw cooperative learning model were successfully improved. Through the application of jigsaw. Eilks & Leerhoff . also showed that the cognitive aspects of students produced were Volume, 11. No. 1, 2022, 39-45 Jurnal Akademika Kimia Table 2.

Table 3 contains the Enough Good evaluation results starting from the first act of cycle one to the third act of cycle two . The data is made in one table to increase learning Each cycle can be seen directly. Table 3. Student evaluation results in cycle 1 and cycle 2 Cycle 1 Action Nilai Total Absorption Avarage % Completeness 1 cycle Cycle 2 Action Based on these data, the CAR problems formulated in the introduction section can be answered and discussed. The problem is whether applying the jigsaw cooperative learning model can improve student achievement in class X MIA4 SMA Negeri 1 Palu, especially in chemistry lessons. 2 cycle Improved learning achievement can be seen from the evaluation results of each action . verage, absorption, and classical completenes. The study results, especially the evaluation results, showed that students' absorption increased when applying the jigsaw cooperative learning Sitti Rahmawati et al. model in chemistry. In the first cycle for the first action, the absorption capacity of 63. 6 was achieved, the second action increased to 67. 0, and the third action became 69. Meanwhile, in the second cycle for the first action, the absorption capacity was 74. 5, which increases the previous step in the first cycle. The dual action became 74. 9, and in the third act, the absorption power was achieved The evaluation results show that students' absorption increases when applying the jigsaw cooperative learning model in chemistry learning. The increase occurred because students contributed knowledge in each cycle that directly took part in learning (Karacop & Doymus, 2013. Karacop, 2. The same thing happened to the application of the jigsaw cooperative learning model to improve student achievement in class X IPA3 SMA Negeri 1 Padang, which can be seen in the results of the evaluation of each action, absorption 5 to 76. 6 and classical completeness from 8 to 92. 9% (Aswirna, 2. Previous research found that cooperative learning leads students to research and construct their knowledge according to students' cognitive characteristics (O'Leary & Griggs, 2. Therefore, an essential part of cooperative learning is how to learn in groups (Doymus, 2. These data indicate an increase in absorption in chemistry learning by applying the jigsaw cooperative learning model, likewise to classical The completeness of each individual is determined by a score of 65 . ccording to the KKM at SMAN 1 Palu with a maximum score of The first cycle for the first action only reached 8%, which means it also met the classical completeness standard even though there were still 10 students who did not complete it individually. the second act, it became 85. 5% which means 6 students did not complete individually, and in the second cycle, it was 85. The third action rose again to 92. 9%, which means three students did not complete individually. Furthermore, the increase in classical completeness is increasingly visible in the second Cycle two for the first act of classical completeness reached 92. 9% . students did not complete individually, the second action became 100%, and the third action became 95. 0% which means there were only 2 students who did not complete individually. It means that there is an increase in classical completeness. this is in line with Muhardini's research . that applying the jigsaw type cooperative learning model in class X9 students of SMAN 2 Mataram can increase classical mastery to 85. 7% with a class average of 75. From the results of this study, it can be said that the application of the jigsaw-type cooperative learning model can improve the chemistry learning achievement of class X9 students of SMA Negeri 2 Mataram. Applying the jigsaw-type cooperative learning model can increase chemistry students' motivation and learning outcomes of class XI MIPA3 SMA Negeri 1 Marga in two cycles, with classical learning mastery reaching 89. (Widarta, 2. Based on the description above, it has been successfully proven that applying the jigsaw cooperative learning model can increase absorption and classical mastery, which means that student learning achievement is proven to improve. It can also be seen and established based on increased student learning outcomes. Existing data show that in cycle one for the first action, the average score was 6, the second action rose to 67. 0, and the third action rose again to 69. Furthermore, in the second cycle, the first action obtained an average value of 74. 5, the second action was 74. 9, and the third was 76. It means that overall all actions tend to increase student learning outcomes. Therefore, it is concluded that applying the jigsaw cooperative learning model in learning chemistry can improve student achievement. Conclusions Based on the results of classroom action research in class X MIA4 IPA SMA Negeri 1 Palu, it can be concluded that applying the jigsaw cooperative learning model can improve student The learning achievement of class X MIA4 students of SMA Negeri 1 Palu in chemistry can be improved if a jigsaw cooperative learning approach is used. It can be proven by two indicators: the cycle's average value and the cycle's classical For the average value, one cycle has an average value of 65. 4 with classical completeness In cycle two, the average value rose again 2 with 98% classical completeness. Thus, it is proven that the cooperative learning jigsaw model approach can improve student achievement in learning chemistry in class X MIA4 SMA Negeri 1 Palu.
