INTRODUCTION
Indonesia is a country that has diversity, both ethnicity, race, culture, regional languages, religion, natural potential, and other. This is a matter of pride for the people of Indonesia. Local wisdom is the results of the earth, artistic creations, cultural traditions, services, services, natural resources, human resources, or others that are the advantages of an area. According to Rahyono [1] local wisdom is obtained through the experience of certain people or ethnic groups from the results of their intelligence. That is, local wisdom itself is a result of certain communities through their experience and not necessarily other communities experience it. These values will be strongly attached to the community and will be remembered throughout the life of the community.
Local wisdom is generally defined as ideas, values, views that are wise, full of wisdom, good value, which are embedded and followed by members of the community [2]. Education that utilizes local excellence in various aspects is education based on local wisdom. The content of local wisdom in education is very important because it can help stakeholders in carrying out an inventory of local wisdom [3,4], learning is more effective by incorporating cultural values in it so that students do not forget the cultures in a particular area [5], as well as local wisdom content of the local area are often found and close to students so that they are easily remembered by students. Tisngati [2] revealed that local wisdom in education can be applied into several aspects such as economic aspects, arts and culture, human resources, languages, information and communication technology, ecology, and others. In the school curriculum, local wisdom is useful for the development of student competencies in facing global competition. Preparation of lesson plans, use of methods and media, and evaluation of learning are efforts that can be done to develop student competency. Therefore, teachers must have competence in preparing lesson plans, using methods, using media, and evaluating learning.  [2]. A teacher in carrying out their duties must have the competence and professional attitude to be taught to students. From these competencies, the teacher must prepare themselves in conveying learning materials well, starting from the preparation of learning plans (lesson plans, tools, models used, worksheets, etc.), implementation (the learning process) and reflection (picture on when the learning process occurs) [12]. Therefore, a teacher must have professional competence, one of which is in the use and manufacture of instructional media in the form of teaching aids to improve the learning process.
According to Yulianti, et al [7] said in theory of teaching tool should, (1) In terms of its form: durable, the shape and color are attractive, simple, not dangerous. (2) In terms of its purpose: right with the purpose of teaching, support the contents of the lesson material, can help the learning process, useful for students during learning, in accordance with the level of thinking of students.
The learning process can be improved by using teaching tool based on local wisdom. The media contains cultural values in it so students do not forget the cultures that exist in a particular area. Therefore, researchers will conduct research related to teacher responses in the manufacture and use of teaching tool based on local wisdom using used stuff. Used stuff are selected as materials for teaching aids because of the high cost of materials used to make teaching aids, used stuff are easily obtained around the environment of students, utilizing and developing existing materials can create critical thinking skills, curiosity, and curiosity seeking truth from participants [13]. In addition, the use of used items for teaching tool can also motivate students to learn and learn new things [14] as well as efforts to overcome environmental damage by utilizing used stuff. This includes the implementation of scientific character and science concepts in learning [15].

METHOD
The study was conducted on March 17, 2020. The subjects of this study were elementary school teacher 1 Potrobangsan, Magelang City. They numbered 8 people consisting of 6 women and 2 men. This research is a quantitative research.
This research was conducted in three stages: (1) Preparation, this stage includes the design of teaching aids, (2) Expert Test, this stage is carried out by assessing the appropriateness of teaching aids by the lecturer, (3) Feasibility Test, this stage is carried out by assessing the feasibility of teaching aids by the teacher.
In accordance with the type of data to be obtained in this study, the research instrument used was a questionnaire. The questionnaire is used to obtain data on the assessment of teaching tool based on local wisdom from used stuff. The questionnaire was given to teachers at Potrobangsan Elementary School 1 Magelang City during training for teaching aids, this questionnaire referred to good indicators of teaching aids.
The data analysis technique uses scale method with Likert scale modification. Likert scale is a psychometric scale that is used in a questionnaire to reveal a person's attitude and opinion towards a phenomenon. Respondents' responses in the form of quantitative data were changed to quantitative data expressed in the form of answers ranging from strongly disagree to strongly agree. This scale can be simplified to just 5 answer scales so that respondents' responses are clearer in which position. After all respondents' answers have been changed into grades 1 to 5, the total value of respondents is calculated by finding the ideal score or expected score for each assessment indicator and overall indicator, after which a percentage is drawn so that a conclusion can be drawn on how appropriate the learning media is used . This calculation can be calculated using the formula below:
