Tujuan dari penelitian ini adalah menghasilkan Lembar Kegiatan Peserta Didik (LKPD) Berbasis Praktikum Materi Perubahan Lingkungan dan daur Ulang Limbah untuk Melatihkan Keterampilan Proses Sains Terintegrasi pada Siswa Kelas X SMA yang layak secara teoritis dan empiris. Selain itu, penelitian ini juga bertujuan untuk mendeskripsikan validitas LKPD berdasarkan hasil validasi, mendeskripsikan kepraktisan LKPD berdasarkan keterlaksanaan pembelajaran, serta mendeskripsikan keefektifan LKPD berdasarkan respon dan hasil tes keterampilan proses sains terintegrasi peserta didik. Penelitian ini merupakan penelitian pengembangan yang mengadaptasi model 4-D yang hanya melalui tahap pendefinisian (define), perancangan (design), dan pengembangan (develop). LKPD diujicobakan secara terbatas pada 20 peserta didik di SMA Muhammadiyah 4 Surabaya. Instrumen yang digunakan adalah lembar validasi, lembar observasi keterlaksanaan pembelajaran, lembar angket respon, dan lembar tes keterampilan proses sains terintegrasi. Data dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan kelayakan teoritis LKPD ditinjau berdasarkan hasil validasi sebesar 3,72 dengan kategori sangat valid. Kelayakan empiris LKPD berdasarkan kepraktisan yang ditinjau berdasarkan hasil observasi keterlaksanaan pembelajaran LKPD 1 dan LKPD 2 masing-masing sebesar 92,83% dan 98,17% dengan kategori sangat praktis, dan keefektifan LKPD yang ditinjau berdasarkan respon siswa sebesar 95% dengan kategori sangat positif serta hasil belajar peserta didik rata-rata 89,29 dengan ketuntasan peserta didik sebesar 90% dan ketercapaian indikator keterampilan proses sains terintegrasi memperoleh rata-rata 88,61%. Dengan demikian dapat disimpulkan bahwa LKPD yang dikembangkan layak secara teoritis dan empiris sehingga dapat digunakan dalam proses pembelajaran.

    The purpose of this research was to produse student activity sheets (LKPD) based on practicum on environmental change material and waste recycling to practice integrated science process skills in class X Senior High School students that feasible theoretically and empirically. In addition, this study also aims to describe the validity of LKPD based on the results of validation, describing the practicality of the LKPD based on the observation of the implementation of learning, and describing the effectiveness of LKPD based on the results of the response and the results of the science process skills tests. This research was development research referred to 4-D model which consisted of define, design, and develoment. LKPD weretested in limited 20 students at SMA Muhammadiyah 4 Surabaya. Instruments used in this research are validation sheets, learning implementation observation sheets, response questionnaire sheets, and integrated science process skills test sheets. The data were analyzed descriptively quantitatively. The results of the study indicate that the theoritical feasibility of LKPD reviewed based on the results of the validation is 3.72 with a very valid category. The empirical feasibility of LKPD based on the results of practically reviewed based on the observations on the implementation of LKPD 1 and LKPD 2 learning, each 92.83% and 98.17% with very practical categories, and the effectiveness of LKPD reviewed based on the student’s response gets 95% with a very positive category and the learning outcomes of students get an average 89.29 with a completeness students by 90% and achievement indicators of integrated science process skills gained an average of 88.61%. Based on the results, it can be concluded that the LKPD developed is theoritically and empirically feasible so that it can be used in the learning process.
