INTRODUCTION
Education is an action undertaken by each individual to gain insights, knowledge, and to develop attitudes and skills.Education is a crucial element for human needs in preparing human resources to enhance the welfare, prosperity, as well as the development of the nation and the state of Indonesia (Maulana, 2021;Puspitaningrum et al., 2018;Sajnani et al., 2020).Education also plays a significant role in enlightening the life of the nation (Tajvidi et al., 2014;Mehrtash dkk., 2019).Human beings can determine and alter their lives through education The rapid advancement of Science and Technology has complex implications for society.Therefore, education is expected to develop the potential of learners to become individuals who have faith and piety towards the One Almighty God, possess noble character, are healthy, knowledgeable, capable, creative, independent, as well as becoming democratic and responsible citizens (Chauhan, 2017;Lynch et al., 2021;Rahardja et al., 2019).Therefore, a good educational system is one that can shape the character of the younger generation to be of high quality and able to adapt to life within the community.
The government itself always strives to enhance and improve the quality of education in Indonesia (Hairunisya & Sunaryanto, 2020;Shufa, 2018;Sofiyan et al., 2019)."One of the efforts made by the government is to update and refine the curriculum, as the curriculum is one of the crucial components in achieving educational goals."(Abdullah et al., 2022;Ramli, 2019;Siahaan & Ani, 2019).The curriculum is a content that contains rules and activities used to achieve educational goals as a reference in the learning process (Arianty et al., 2021;Puad & Ashton, 2022).The enhanced curriculum has undergone changes towards a more positive direction.(Hairunisya & Sunaryanto, 2020;Kurniaman & Noviana, 2017;Muhajir et al., 2020).
However, in the current era of globalization, often local wisdom values are marginalized within an education system that tends to adopt a general national curriculum (Ratna et al., 2022;Triastari et al., 2021).However, local wisdom is an inseparable part of a society's identity and holds significant potential to enhance students' learning outcomes.The diversity or local wisdom present in each region is crucial to introduce to the learners (Arianty et al., 2021;Habaridota, 2022;Sinthya & Ramadan, 2021).Learning that utilizes the surrounding environment as a source of study is considered more effective and beneficial for both teachers and students.Students also feel that the conducted learning is more meaningful (Wendo et al., 2022;Widiastuti, 2017).This is because the learning becomes increasingly contextual, allowing students to connect the learning materials with their environment, making it easier for them to comprehend the subject matter.
The reality is that many teachers do not introduce and integrate local wisdom from the local region into their teaching materials (Meilana & Aslam, 2022;Nabila et al., 2021;Putri & Ananda, 2020).Teachers tend to prefer using existing teaching materials (Astra et al., 2020;Raharjo et al., 2017), meanwhile, students require comprehensive information about local wisdom-based learning (Asrial dkk., 2021).Therefore, current students are often perceived as having insufficient knowledge about local culture.This is evidenced by the significant number of students who are unaware of their local wisdom (Asrial dkk., 2021).Students are more familiar with and have a greater affinity for foreign cultures.This is because they are unaware that their local area possesses such diverse local wisdom.
As observed among the students in Bondowoso district, they are unaware of the local potential in their residential areas.Based on the interview findings conducted with fourth-grade teachers at SDN Poncogati 1 Bondowoso, it was revealed that Bondowoso possesses a diverse range of local wisdom that is essential to integrate into the learning process.The instructional materials used in fourth-grade classes include thematic books and student worksheets.The content found in the thematic book, especially in theme 7, has been adjusted to match the characteristics of the students.However, material related to the local environment where the students reside has not been taught.Therefore, it is important to introduce locally-based learning materials from Bondowoso to ensure that students become acquainted with and understand the culture or local wisdom of their residential area.Additionally, concerning the implementation of instruction, it is evident that the student worksheets used in the learning process are not well-tailored to the students' environmental context.The content of the book is generally examined and lacks alignment with the students' environmental conditions and capabilities.However, the diverse characteristics, environments, needs, and abilities of students in each region are essential aspects that should be integrated into the learning process.
The purpose of introducing local wisdom is to help students better understand the taught material, as well as to serve as an effort to introduce the local wisdom of the students' residential area, so that it is not eroded by the progress of time (Meilana & Aslam, 2022;Sinthya & Ramadan, 2021).In this context, the research focuses on the development of locally-based student worksheets with Bondowoso local wisdom.student worksheets is an instructional material used by teachers in the learning process, containing summarized content and a collection of activities or tasks that students need to complete (Astawan & Agustiana, 2020).The student worksheets to be developed will be presented as a form of reinforcement, encompassing the same basic competencies as in the thematic book.However, the learning material within will include content based on Bondowoso's local wisdom, encompassing culture and arts, such as traditional houses (Tanean Lanjhâng), traditional attire (Kacong Jebing), and traditional dances (Tari Petik Kopi and Teri Singo Ulung) (Dewi et al., 2021;Efendi & Triaditya, 2020;Swastika et al., 2016;Winarni, 2019).
Bondowoso is an eastern region of East Java rich in unique and diverse local wisdom (Mashoed, 2004).The integration of local wisdom into the student worksheets is expected to enhance the holistic learning outcomes of students, enrich their learning experiences, and foster a strong cultural identity.
The presence of locally-based student worksheets from Bondowoso's local wisdom is expected to enhance students' learning outcomes, transform the learning process from being teacher-centered to student-centered, meaning that students need to be more active in engaging with the learning process.These locally-based student worksheets are suitable instructional materials for students, as they help students understand and comprehend the concepts being taught, especially Bondowoso's local wisdom, through a systematic learning approach.The developed student worksheets will also be more practical.Besides covering content related to the students' living environment, these student worksheets include practice questions that help students exercise their minds to think and remember the previously learned material.This facilitates the teaching process for educators, as students are accustomed to independent learning by working on the practice questions provided in the student worksheets.Furthermore, these developed student worksheets serve as instructional materials for teachers to create an engaging and effective learning environment.
In the development of educational science, there are studies related to the use of local wisdom in learning.According to previous research, the development of student worksheets effectively enhances learning outcomes.The validation results of the product obtained a score percentage of 94.5% and were categorized as highly appropriate (Putri & Ananda, 2020).Based on these results, it is evident that locallybased student worksheets are suitable for use in learning.Similar studies also revealed that validation results obtained a score percentage of 88.3%, while the percentage from the student response questionnaire was 98% with a highly effective category (Arianty et al., 2021).Other studies also indicate that locally-based student worksheets are effective in enhancing student learning outcomes and meet the criteria for being highly suitable for use in learning (Aini & Fathoni, 2022).Based on previous research, it can be concluded that the development of locally-based student worksheets is effective for use in learning and can enhance student learning outcomes.However, there is still a research gap regarding the development of locally-based student worksheets with Bondowoso's local wisdom and its impact on student learning outcomes.
There is a gap in the literature regarding the development of locally-based student worksheets with Bondowoso's local wisdom.While some studies have explored the integration of local wisdom in learning, research specifically focused on the development of locally-based student worksheets with Bondowoso's local wisdom is still limited.Therefore, this study aims to fill this gap by developing student worksheets that can specifically integrate Bondowoso's local wisdom.Furthermore, the research gap lies in the limited knowledge regarding the validity, effectiveness, and practicality of locally-based student worksheets with Bondowoso's local wisdom in enhancing student learning outcomes.While there have been some previous studies indicating the positive impact of integrating local wisdom in learning, this study offers a unique contribution by exploring the validity, effectiveness, and practicality of locally-based student worksheets with Bondowoso's local wisdom specifically for fourth-grade students.
The literature review indicates a need for further research in the development of student worksheets based on Bondowoso's local wisdom.Relevant studies in this context are still limited, and the conducted research so far has yielded varied results.Therefore, this study aims to address this knowledge gap by investigating the validity, effectiveness, and practicality of locally-based student worksheets with Bondowoso's local wisdom in enhancing the learning outcomes of fourth-grade students.Considering the challenges faced by students, teachers, and the school, efforts are being made to address these issues by developing instructional materials in the form of locally-based student worksheets with Bondowoso's local wisdom.These student worksheets will be researched and tested with students.The reasons driving the development of these student worksheets are: (1) based on previous research, locally-based student worksheets have proven effective in enhancing student learning outcomes, (2) students lack awareness and understanding of Bondowoso's local wisdom, (3) the instructional materials used in learning lack variety and fail to engage students' enthusiasm, and (4) there is a lack of instructional materials based on Bondowoso's local wisdom.The purpose of this research is to examine the validity, effectiveness, and practicality of locally-based student worksheets with Bondowoso's local wisdom as an effort to enhance the learning outcomes of the theme 'The Beauty of Diversity in My Country' for fourth-grade students.

The second phase is the planning and development phase.In this phase, you will formulate a research proposal that includes the research title, research problem statement, research objectives and benefits, literature review, research methodology, research procedures, as well as instruments and schedule of activities.The third phase is the development of the initial product design, which is in the form of student worksheets based on the local wisdom of Bondowoso.The fourth phase is the validation of the product design.The validation of the student worksheet design is conducted by four validators, including 2 content experts, 1 media expert, and 1 practitioner expert.The fifth phase is the revision of the initial product.This revision phase is carried out based on the suggestions and criticisms from the validators (Carlos et al., 2020;Kumalasari et al., 2023).There were several revisions suggested by the validators, ranging from language aspects, content feasibility aspects, and graphical aspects.The sixth phase is the trial usage.This phase aims to gather feedback or responses from students regarding the student worksheet based on local wisdom from Bondowoso (Carlos et al., 2020;Masyhud, 2021).The trial usage of the student worksheet product based on local wisdom from Bondowoso was conducted on a small scale with 15 students from class IV of SDN Badean 1 Bondowoso as respondents.During the trial usage activity, each student was given the student worksheet based on local wisdom from Bondowoso.The trial usage of the student worksheet resulted in a score of over 80% for each answer point.Therefore, no revisions were needed, and the research proceeded to the eighth phase, which is the effectiveness trial.
The effectiveness trial phase aims to determine the effectiveness of the student worksheet product based on local wisdom from Bondowoso (Carlos et al., 2020;Sinakou et al., 2019).The effectiveness trial of the product in this research was conducted in Class IV A and IV B of SDN Poncogati 1 Bondowoso using an experimental method.This phase employed a pre-test post-test experimental design.The trial of the student worksheet product based on local wisdom from Bondowoso was conducted in Class IV A as the experimental group and Class IV B as the control group.Class IV A, the experimental group, received instruction using the new product, which is the student worksheet based on local wisdom from Bondowoso.Meanwhile, Class IV B, the control group, received instruction using the old product, which is the school's standard student worksheet.After the instructional process, both classes were assessed using the same measurement tool (test).The evaluation of the effectiveness criteria of the student worksheet based on local wisdom from Bondowoso was determined using the Independent Sample t-test and Relative Effectiveness Test based on pretest and posttest results.The Independent Sample t-test aimed to determine the level of effectiveness of the student worksheet based on local wisdom from Bondowoso, while the Relative Effectiveness Test was used to assess the level of learning achievement effectiveness among the students (Hasna N, 2023).
The data analysis conducted indicates that the development of the student worksheet based on local wisdom from Bondowoso significantly enhances the learning outcomes of Grade IV students.The students experienced an improvement in their understanding of concepts and the application of knowledge in their everyday lives.This suggests that the use of local wisdom as a learning context can motivate students and help them connect learning concepts to real-life experiences, thereby reinforcing their understanding (Asmah et al., 2022;Fatmawati et al., 2021;Wardani & Suniasih, 2022).
The findings of this research are consistent with previous studies that have shown that the use of local cultural contexts in education can enhance students' learning interest and outcomes (Ayurachmawati et al., 2022;Hanafie Das et al., 2022;Pane et al., 2022).Previous research has found that a local wisdombased learning approach helps students engage in a more effective learning process (Hasna N, 2023;Wulan et al., 2019).Other studies have also proven that developing instructional materials based on local wisdom is effective in enhancing students' learning outcomes (Azizah & Alnashr, 2022;Rahayu et al., 2020).These findings support the results of this study, where the use of local wisdom from Bondowoso also has a positive impact on students' learning outcomes.This finding provides a deeper understanding of the importance of integrating local wisdom into education to enhance students' learning achievements.In a broader context, this research demonstrates that an instructional approach that connects subject matter with local culture can enrich the learning experience and facilitate a deeper understanding of academic concepts.Therefore, the generalization of this study is that incorporating local wisdom into student worksheets can be an effective strategy to improve students' learning outcomes in various educational contexts.
This study has significant strengths.The main advantage of this research lies in its innovative approach to developing student worksheets based on local wisdom from Bondowoso.This approach allows Suhartiningsih / Learning Revolution with Student Worksheets Based on Bondowoso Local Wisdom for Fourth Grade of Elementary School students to learn within their own cultural context, providing an authentic and relevant learning experience.By integrating local wisdom into the student worksheets, this study offers students the opportunity to explore academic concepts through the lens of their familiar culture (Astuti, 2021).The cultural diversity of Bondowoso that is reflected in the student worksheets provides a richer and deeper dimension to the learning process.Additionally, this study has provided concrete evidence of the effectiveness of the student worksheets based on local wisdom from Bondowoso in enhancing student learning outcomes.Students who used these student worksheets experienced significant improvements in their understanding of concepts, application of knowledge, and learning interest.These results indicate that using local wisdom as a learning context has a significant positive impact on student learning achievements (Kudsiah et al., 2022;Rahmawati & Margunayasa, 2022).The findings of this research have several important implications.Firstly, the use of student worksheets based on local wisdom can serve as a relevant and engaging alternative teaching method for students.This can enhance the connection between learning and students' everyday lives, thereby increasing their learning interest and motivation (Rizkiwati et al., 2022;Tohri et al., 2022).Secondly, the utilization of local wisdom can also aid in preserving and appreciating local cultural heritage, as well as strengthening the identity of the students (Haerunnisa et al., 2020;Rahmadanty et al., 2022;Wiyani, 2022).
This research has certain limitations that need to be considered.The study was conducted in a single elementary school in Bondowoso, which means the results may not directly apply to other school contexts.Furthermore, the research focused on 4th-grade students, so generalizing the findings to higher grade levels or school levels needs further investigation.Based on the results of this study, several recommendations are offered for both research and educational practitioners.First, it is advised to involve more schools and regions in similar studies to achieve stronger generalizations about the use of local wisdom in education.Additionally, research involving different age groups and grade levels should be conducted to ascertain the extent of the effectiveness of using local wisdom in education.Educational practitioners are also encouraged to adopt a teaching approach that integrates local wisdom to enhance students' learning outcomes continuously.

CONCLUSION
