INTEGRATING MATHEMATICS LOCAL WISDOM BASED THROUGH WORKSHEET IN BILINGUAL PROGRAM

Elementary school mathematics learning is generally taught classically by teachers. By using the lecturing method and the material is also general nationally. There is no regional element (local wisdom values) there is no technological element. In this study, researchers discussed the integration of local wisdom-based mathematics learning through the development of student worksheets with Banten culture in the bilingual program at the SDIT Assa'adah Global Islamic School (AGIS) Elementary School, Serang City. The aimed of this research is to introduce Banten regional culture to elementary school students in a bilingual program with Indonesian and English trough mathematic worksheet. Researchers also simultaneously introduce foreign languages that are commonly used. This study used Research and development in the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) method. the population of research are IT AGIS Elementary School students, and the sample is grade 4 SD IT AGIS. In this study, researchers drafted a grade 4 bilingual mathematics worksheet. The results were validated by 3 experts recommended worthy of being tested on students.


INTRODUCTION
Mathematics is a science that plays an important role in life and is a useful branch of science for engaging and socializing in society (Purwanti, 2016). In fact, there are many problems faced, namely the ability of students to solve math problems is still low, this is because when learning mathematics students tend to memorize formulas, and only imitate the examples given, thus each time a different question is given, the student has not been able to work on the question even though the student has been given handbook (Anggoro, 2015). Currently, not only for senior high school (SMA) and junior high school (SMP) there are bilingual programs, but also at elementary schools (SD) there are also bilingual programs. One of them is mathematics. Mathematics in bilingual programs is still a very scary paradigm, because mathematics has a very abstract nature (Hasbullah, 2018).
The contents of student worksheets must also be able to develop students' thinking skills. This is in accordance with the research that has been done that student worksheets should be able to support and encourage students to be able to think, analyze, and compile the results of their own activities (Hernawati, 2015). Mathematics subjects in elementary school education units include the following aspects: (1) Numbers, (2) Geometry, (3). Data Processing. Number coverage includes numbers and figures, calculations, and estimates. This is stated in the syllabus for the fourth grade of elementary school at first semester in curriculum 2013. Using bilingual student worksheets in mathematics learning can improve students 'ability to solve math problems in English with an indicator of success in research is the increase in students' ability to solve math problems in English with the attainment of the minimum completeness criteria (KKM) (Zuraidah, 2017). ADDIE method developed by Dick and Carrey, developing local wisdom bilingual worksheet in Math that have been validated by material experts, media experts, linguists and trials, the average score is very good in the material category, the media gets very good scores and very good also in the field of language (Sandiyanti, 2018).
Student worksheets is an instruction sheet for students to carry out an activity in the learning process, as well as a list of tasks and a place to record observations (Astuti, 2017). The width of this activity is usually in the form of instructions, steps to complete a task (Majid, 2006). Adding student worksheets contains a set of basic activities that must be done by students to maximize understanding in an effort to form basic abilities according to indicators of achievement of learning outcomes that must be taken (Triyanto, 2015). Local wisdom should also be preserved to develop regional culture, but it is more often ignored in learning, only briefly conveyed to students, not discussing the roots of regional culture. This is only understood and cannot be applied in everyday life (Ulfah, 2018). Learning tools based on local wisdom developed in valid categories so that they are quite effective in improving students' problem solving abilities (Wahyuni, 2015). Furthermore, learning that is oriented towards local wisdom gives a more contextual impression in learning therefore students easily understand the material being studied (Fannie, 2014).

METHOD
The data analysis technique used in this research is descriptive analysis, namely by calculating the average score of the validity score of each validity indicator of the student worksheet and the average used response score. Validation score given by the expert as a result of validation. The feasibility of student worksheets developed from user response scores (on a small-scale trial). This research is a research and development (Research and Development). This study uses the ADDIE research model, namely analysis, design, development, implementation and evaluation (Gunaydin, 2016). The systematic process is represented by the acronym ADDIE, namely analysis, design, development, implementation, evaluation (Aldoobie, 2015). This research is in accordance with the ADDIE research stages, which begins with the analysis process and the evaluation process. The development design used in this study is ADDIE, describing the ADDIE design stages as follows :

Figure 1. ADDIE design stages
At the analysis stage, the researcher conducted a learning analysis. it is found that the learning is centered on the teacher. The student worksheets made by the teacher used have not been able to fully assist students in learning objectives because the concepts proposed are still very general, the examples of stories presented do not contain elements of local wisdom that are appropriate to the child's learning environment. Based on the analysis, the use of bilingual mathematics student worksheet based on local wisdom is one way to overcome this problem. At the design stage, the writer determines the format and design. At the develop stage, the designs obtained from the design stage are developed into bilingual Mathematics Worksheets based on local wisdom. The response of teachers and students about the developed bilingual worksheets local wisdom based is good.
The implementation of this research and development, the researcher used two types of data collected, namely, quantitative data and qualitative data. The data collection technique used to obtain data on student responses to illustrated bilingual student worksheets used a questionnaire by distributing a G-form link. The development product will end when the assessment score on this student worksheet has met the eligibility requirements with the suitability level of the material and design, which is categorized as very attractive. By having the following categories: The criteria for drawing conclusions on the developed student worksheet are defined as follows: a. Each component of the assessment for the student worksheet format is declared valid if the validity is high according to table 3. b. Each component of the assessment of the contents of the student worksheet is declared valid if each statement on the indicator gets a score of 3 and 4, the validity is high or very high according to table 2. Practicality user response student worksheets based on local wisdom, seen from the responses of teachers and students to student worksheets. Student worksheets are declared fit for used if the user's response is in the high or very high category.

Result and Discussion
The development of student worksheets based on local wisdom that has been carried out show the following results: Based on the expert validation above, design format of worksheet got average score 3,305 was very good criterion. It means that format of worksheet design was valid to be used as material development that propose by researcher. Based on validation experts Questionaire, got average score 3,37 was very good criterion. It means that worksheet was valid to be used for 4 th grade students as their material, exercise and references in their learning. In this research and development, the researcher drafted material into bilingual worksheet of mathematic with local wisdom values and without disseminated to large group test because the pandemic of Covid 19, the student learns at home by daring and also the drafted need more critic to be great product. Score of questionnaires from teacher and students as user of development product delivered by G-form on Whatsapp given for teacher and students, it got average score very good criterion. it could be references for the researcher to be continue the worksheet development until disseminated and granted ISBN and HAKI and could be useful for students 4 th elementary school in Banten or Indonesia.

CONCLUSION
The development of student worksheets on bilingual mathematics subjects based on local wisdom can provide opportunities for students to increase knowledge and build creativity in learning English. Through this learning strategy, researchers make teaching materials that can help teachers in the classroom in providing material and students can easily understand the material provided by the teacher in class. In making student worksheets, researchers used expert tests for validation. As well as mathematical knowledge, the use of English, the context of the suitability of the use of animation, the suitability of the cover design. In this case, the researchers only make a draft student worksheet consisting of 2 chapters, namely the operation of counting numbers and multiples and a factor of a say according to the additional output in submitting a research grant proposal for novice lecturers. In addition, it will be continued in the next grant by making textbooks for grade 4 elementary schools, therefore that researchers can contribute creative works to the world of education. This is almost the same as the research which explains that the developed worksheets are declared valid where the validity of the student worksheet format is high. This is similar to research that describes the results of the feasibility test for teaching material products in the form of bilingual worksheets with a contextual approach both from the test of material experts, media experts, linguists, teachers and students that can be used or valid, therefore it can help teacher learning in class (Veny, 2014).
