Penelitian Ini Bertujuan Untuk Menghasilkan Perangkat Pembelajaran IPA Berbasis Integrasi Pendekatan Saintifik Berupa Silabus, Rencana Pelaksanaan Pembelajaran (RPP) Dan Lembar Kerja Siswa (LKS) Pada Materi Perubahan Sifat Benda Untuk Mengetahui Kualitas Perangkat Pembelajaran Berdasarkan Aspek Kelayakan Yang Ditinjau Dari Validasi Para Ahli, Aspek Kepraktisan Yang Ditinjau Dari Angket Respon Guru Dan Observasi Keterpakaian Produk, Dan Aspek Keefektifan Ditinjau Dari Angket Respon Siswa Dan Tes Hasil Belajar Siswa.
Penelitian Pengembangan Yang Dilakukan Merupakan Adaptasi Tahap-Tahap Pengembangan Four-D, Yaitu Define, Design, Develop Dan Dessiminate. Namun Tahap Penyebaran (Dessiminate). Instrumen Yang Digunakan Berupa Silabus, Rencana Pelaksanaan Pembelajaran (RPP), Lembar Kegiatan Siswa (LKS), Tes Hasil Belajar (THB), Angket Keterpakaian Produk, Angket Respon Siswa Dan Angket Respon Guru. Hasil Penelitian Ini Berupa Perangkat Pembelajaran IPA Berbasis Integrasi Pendekatan Saintifik Dan Keterampilan Proses Sains Pada Materi Perubahan Sifat Benda Di Kelas V SDN 027 Tarakan Berupa Silabus, RPP Dan LKS.
Hasil Penelitian Menunjukkan Kualitas Produk Yang Dihasilkan Berdasarkan Aspek Kelayakan Yang Ditinjau Dari Hasil Validasi Ahli Bahasa Diperoleh Nilai 92,5%, Ahli Konstruk Diperoleh Nilai 88,6%, Ahli Materi Diperoleh Nilai 90% Dan Ahli Desain Diperoleh Nilai 77,5%. Aspek Kepraktisan Diperoleh Dari Penilaian Lembar Observasi Keterpakaian Produk Diperoleh Nilai 92,5% Dan Berdasarkan Dari Penilaian Angket Repon Guru Diperoleh Nilai 100%. Sementara Itu Untuk Aspek Keefektifan Berdasarkan Penilaian Angket Respon Siswa Diperoleh Nilai 88,3% Dan Berdasarkan Hasil Belajar Siswa Setelah Menggunakan Perangkat Pembelajaran IPA Berbasisi Integrasi Pendekatan Saintifik Dan Keterampilan Proses Sains Menunjukkan Sebanyak 88% Siswa Mencapai Kriteria Ketuntasan Minimal (KKM=75).

This Research Aims To Produce Science-Based Learning Tools Based On The Integration Of Scientific Approaches In The Form Of Syllabus, Learning Implementation Plan And Student Worksheet On The Material Changes To Know The Quality Of Learning Devices Based On Feasibility Aspects Reviewed From The Validation Of The Experts, The Aspect Of Practicality Which Is Reviewed From Teacher Questionnaire Responses And Product Exposure Observations, And Effectiveness Aspects In Terms Of Student Response Questionnaires And Student Learning Outcomes. Research Development Is An Adaptation Of The Development Stages Of Four-D, Namely Define, Design, Develop And Dessiminate. But The Stage Of Dissemination (Dessiminate). The Instruments Used Are Syllabus, Learning Implementation Plan, Student Activity Sheet, Learning Result Test, Product Disposal Questionnaire, Student Response Questionnaire And Teacher Response Questionnaire. The Results Of This Study Are Science-Based Learning Tools Based On The Integration Of Scientific Approach And Science Process Skills On The Material Change Of Object Properties In Class V SDN 027 Tarakan In The Form Of Syllabus, Learning Implementation Plan And Student Worksheet. The Results Showed That The Quality Of The Products Produced Based On The Feasibility Aspect In Terms Of The Validation Of The Linguist Obtained 92.5%, The Constructor Obtained The Value Of 88.6%, The Material Expert Obtained The Value Of 90% And The Design Expert Obtained 77.5%. Aspects Of Practicality Obtained From The Assessment Of Product Descriptions Observations Obtained Value 92.5% And Based On The Assessment Repon Teacher Obtained A Value Of 100%. Meanwhile, For The Effectiveness Aspect Based On Students 'Questionnaire Assessment, The Score Was 88.3% And Based On The Students' Learning Outcomes After Using Science-Based Instructional Tools Based On The Integration Of Scientific Approach And Science Process Skills Showed That 88% Of Students Achieved The Minimum Mastery Criteria (KKM = 75).
