Pengembangan Instrumen Tes Literasi Sains Sains Pada Materi Suhu dan Kalor dengan Mengintegrasikan Kearifan Lokal Pembuatan Batik Karang Khas Kabupaten Tuban Development

Development of Science Literacy Test Instrument on Temperature and Heat Materials by Integrating Local Wisdom of Making Batik Karang from Tuban Regency 

        Tantangan pembelajaran di abad ke-21 menuntut peserta didik menguasai berbagai keterampilan, salah satunya adalah keterampilan literasi sains yaitu kecakapan dalam memahami dan menerapkan konsep sains dalam kehidupan sehari-hari. Tujuan penelitian ini adalah mengembangkan instrumen tes literasi sains yang terintegrasi kearifan lokal pembuatan batik Karang khas Tuban dan mengidentifikasi profil kemampuan literasi sains peserta didik pada materi suhu dan kalor. Metode yang digunakan dalam penelitian ini adalah metode pengembangan model ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Pengumpulan data dilakukan menggunakan metode wawancara, angket validasi, dan tes untuk mengukur kemampuan literasi sains. Data penelitian berupa validitas teoritis dan empiris instrumen tes. Instrumen tes diujicoba pada 30 mahasiswa tingkat pertama Program Studi Pendidikan Fisika Universitas Negeri Surabaya dan diimplementasikan pada 70 peserta didik kelas XI-G dan XI-F di SMA Negeri 1 Tuban. Hasil uji validitas teoritis memenuhi kriteria layak berdasarkan nilai Percentage of Agreement (PoA) sebesar 97,44% untuk aspek isi, 97,30% untuk aspek konstruksi, dan 100% pada aspek bahasa. Sedangkan untuk validitas empiris diperoleh hasil sebanyak 67% dari 15 soal berkategori valid sedangkan 33% berkategori tidak valid. Nilai reliabilitas yang diperoleh sebesar 0,690 berarti instrumen tes yang dikembangkan termasuk reliabel kategori tinggi. Selain itu, nilai tingkat kesukaran butir soal instrumen tes yang dikembangkan telah mencakup variasi tingkat kesukaran, dengan rincian 67% butir soal berkategori mudah, 27% sedang, dan 6% sukar, dalam rentang taraf kesukaran kisaran 0,294-0,973. Serta nilai daya pembeda instrumen berada pada kisaran 0,105 hingga 0,293, dengan 67% butir soal berkategori cukup dan 33% berkategori jelek. Profil kemampuan literasi sains peserta didik menunjukkan hasil 4 peserta didik dengan kategori sangat rendah, 13 peserta didik berkategori rendah, 11 termasuk kategori cukup, 24 peserta didik termasuk kategori tinggi, dan 18 peserta didik berkategori sangat tinggi. Dengan demikian, dapat disimpulkan bahwa instrumen tes literasi sains pada materi suhu dan kalor yang terintegrasi kearifan lokal pembuatan batik Karang khas Tuban yang telah dikembangkan layak digunakan untuk mengukur kemampuan literasi sains peserta didik.

The challenges of learning in the 21st century require students to master various skills, one of which is science literacy skills, namely the ability to understand and apply scientific concepts in everyday life. The purpose of this study was to develop a science literacy test instrument that integrates local wisdom in making Karang batik typical of Tuban and to identify the profile of students' science literacy abilities on temperature and heat materials. The method used in this study is the ADDIE model development method (Analysis, Design, Development, Implementation, and Evaluation). Data collection was carried out using interview methods, validation questionnaires, and tests to measure science literacy abilities. The research data were in the form of theoretical and empirical validity of the test instrument. The test instrument was tested on 30 first-year students of the Physics Education Study Program, Surabaya State University and implemented on 70 students of grades XI-G and XI-F at SMA Negeri 1 Tuban. The results of the theoretical validity test met the criteria for eligibility based on the Percentage of Agreement (PoA) value of 97.44% for the content aspect, 97.30% for the construction aspect, and 100% for the language aspect. Meanwhile, for empirical validity, the results obtained were 67% of the 15 questions were categorized as valid while 33% were categorized as invalid. The reliability value obtained was 0.690, meaning that the developed test instrument was included in the high category of reliability. In addition, the level of difficulty of the test instrument items developed has covered variations in the level of difficulty, with details of 67% of the questions being categorized as easy, 27% as moderate, and 6% as difficult, in the range of difficulty levels from 0.294 to 0.973. range 0.294-0.973. And the value of the instrument's discriminatory power is in the range of 0.105 to 0.293, with 67% of the questions in the sufficient category and 33% in the poor category. The profile of students' science literacy skills shows that 4 students are in the very low category, 13 students are in the low category, 11 are in the sufficient category, 24 students are in the high category, and 18 students are in the very high category. Thus, it can be concluded that the scientific literacy test instrument on the material of temperature and heat integrated with the local wisdom of making Karang batik typical of Tuban that has been developed is suitable for measuring students' scientific literacy abilities.
