various learning devices that can actively develop learners, one of the teaching materials that can be used in the curriculum 2013 is the work plane of the learners or Students worksheets.
Though it has been a lot LKPD what developed, but still alone cannot match the 2013 curriculum that is expected to help learners in building high-level thinking and active in learning in accordance with the 2013 curriculum in which demanding active learners in learning (Riyadi, Syarifah, T. J., & Nikmaturrohmah, P. , 2021;and Andriyani, Y.E., Ernawati, W.D.M., & Malik, A., 2018).
Student worksheets which developed to improve the high-level thinking skills learners refer to the syntax of the project-based learning model.Where the project-based learning syntax is selected because the project-based learning is a learning model based on learners so that it can obtain concepts by experiment or practicum.So learners expect to be able to investigate why an event can occur, collecting data and processing scientifically discover to find answers form a problem.The project based learning model is a model that is concerned about the importance of understanding of understanding or important ideas against a science, through the involvement of participants actively in the learning process.In learning-based discoveries, learners are encouraged to learn with most through their own active involvement in which teachers are facilitators for learners to have experiences and experiment that enables them to find knowledge for themselves (Hosnan, 2014).
Experts say that Students worksheets is one of learning resources that can be developed by teachers as a facilitator in learning activities (Aini, Nur A., et al., 2019).The LKPD are in the arrangement can be planned and developed in accordance with the conditions and situations of learning activities to be faced (Widjajanti, 2008).According to the association of education and communication technology (AECT) in ethicology of the word media is a plural form of the medium derived from the Latin is "Medius" which means middle.So, in the Indonesian medium can be in the artistic as the intermediary media can lead to a unit or forward the information.According to Trianto (2007), in the learning process is a process of learners to develop knowledge, thinking, and psychomotor skills.In learning IPA is something to be done by learners instead of something that is done to learners.Where in the current curriculum used demands active learners in learning and optimizing intelligence or talent that has been, then from it is done in the improvement in the understanding and the thinking skills of learners with the making of learning media in the form of speakers of learners.
Student worksheets can be developed with the creativity of teachers, such as creating a colored book and can invite learners to be imagined.It that can be used in learning should invite the activity of learners.One of them can use it with the corresponding model one of the project-based learning so that it can cause liveliness of learners.According to Hidayat (2013) there are several components in the purpose of using the workpiece of the leisure (Student worksheets) at the time of learning process (1) can provide the knowledge, attitudes and skills that need to have been in by learners, (2) can check the extent to the level of understanding of learners in learning to learning materials that have been given by the teacher, (3) can provide knowledge, attitudes, and skills that need to have been in by participants, (4) can check the extent to which levels of understanding of learners in learning to learning material that need to have been in by the teacher, (5) can develop and apply difficult learning material in conviction orally, (6) can help learners in obtaining material through learning activities containing tasks and can be done in practice.
The science learning about magnets is one of the physics materials in the invitation to class VI.This material is the basis of physics learning therefore learners should be understanding the concepts in the material in depth so if the launch is given the exercise or test of learners can answer with you in the other learners will be easy to learn the next science material.In fact, still there are learners who have not midge in the material and cause misconceptions while studying learning materials.This is not leaving many learners not interested to study the science material related to physics.One way to help learners in understanding this material is by using LKPD that corresponds to learning.
Based on the description above the researcher has done initial observation at any of the elementary schools in West Aceh that is at the SD Negeri 24 Meulaboh Aceh Barat precisely on classroom VI in September 2021.In the observation that has been done to make that masi there are many constraints in the learning process related to the application of learning tools in the form of Student worksheets in accordance with the curriculum 2013 demanding learners can be active in learning or learning centered to learners.But in fact, it is used by some teachers at the school is not much different from the workplace that is in the teaching books available at school.Where the existing questions in Student worksheets are not in the category about the hots but it is still the loss category, so it is to make the learners cannot think high levels so difficult learners in answering the problems in the category of the Hots.From the issue, researchers are interested in conducting research on the development of the projected work spread (Student worksheets) based on projected based learning to improve high-level thinking skills (HOTS) on magnetic material in SD Negeri 24 Meulaboh, Aceh Barat.  the entrepreneurship theme on magnetic material.In this activity the researcher performed the initial observation that was done on SD Negeri 24 Meulaboh Aceh Barat, So the researchers found where in the learning process, learners still have not been able to think high levels.The exam results on thematic subjects especially in the class IPA classes VI Indicating that by 2020 learners still received 71 of the value of minimum completeness criteria 75 and in 2021 obtained 73 values that were still under minimal completeness which is valid 77 if viewed in the outline, the researcher has that the result of learning students is learned in the IPA lesson is still very low, this indicates that learners have not been able to think high levels.Seeing the value of the thrill of learners under KKM, the researcher did the development of teaching materials in the form Student worksheets based on project learning-shaped prints with entrepreneurial themes on learning IPA with magnetic material has gotten the result of the previous stage of define and design stage and already in completion then produce the initial design of the media called on the draft I. Then the next stage is the development stage or development stage, the first phase is done in the process of development stage this is validate and evaluation.
