ABSTRAKPenelitian ini bertujuan untuk: 1) mengetahui karateristik modul IPA terpaduberbasis inkuiri terbimbing untuk meningkatkan keterampilan proses sains siswadengan tema alat pendengaran manusia dapat digunakan sebagai sumber belajar siswadi SMP; 2) mengetahui kelayakan modul IPA terpadu untuk meningkatkanketerampilan proses sains siswa; 3) mengetahui keefektifan modul IPA terpadu berbasisinkuiri terbimbing untuk meningkatkan keterampilan proses sains siswa.Penelitian pengembangan modul IPA terpadu ini menggunakan prosedur modelBorg & Gall dimodifikasi terdiri 7 tahapan: 1) penelitian pendahuluan danpengumpulan informasi, 2) perencanaan, 3) pengembangan bentuk produk awal, 4) ujicoba kelompok kecil, 5) revisi terhadap produk utama, 6) uji coba pemakaian produk, 7)revisi terhadap produk akhir. Kelayakan modul divalidasi oleh ahli pengembanganmodul, ahli materi, ahli desain dan keterbacaan, guru IPA (praktisi), dan siswa.Pengumpulan data dilakukan dengan menggunakan angket, lembar observasi,wawancara, dan tes. Analisis data yang digunakan selama pengembangan adalahanalisis deskriptif, analisis kelayakan modul berdasarkan skor kriteria. Keterampilanproses sains dianalisis dengan mengunakan uji-t (t-test) dengan desain posstest onlycontrol group design.Hasil penelitian dapat disimpulkan sebagai berikut: 1) pengembangan modulIPA terpadu berbasis inkuiri terbimbing dengan tema alat pendengaran manusia yangtelah dikembangkan memiliki karakteristik: a) modul yang utuh, berdiri sendiri; b)materi IPA terpadu bersifat holistik, bermakna, dan aktif dengan aktivitas modul berupasintak pembelajaran inkuiri terbimbing untuk meningkatkan keterampilan proses sains.Cara penyusunannya menggunakan prosedur pengembangan yang diadaptasi daripengembangan Borg & Gall. 2) modul IPA terpadu yang dikembangkan layak untukditerapkan pada tema alat pendengaran manusia. Kelayakan modul IPA terpaduberdasarkan penilaian dari ahli, praktisi, dan respon siswa yang secara keseluruhanmemberikan kategori sangat baik pada produk pengembangan, 3) modul IPA terpaduberbasis inkuiri terbimbing dengan tema alat pendengaran manusia efektifmeningkatkan keterampilan proses sains (sig. 0,000) dan hasil belajar kognitif (sig.0,000). Besarnya peningkatan dilihat dari gain score keterampilan proses sains siswa0,38 (sedang) dan gain score hasil belajar kognitif 0,42 (sedang).Kata kunci: Modul IPA Terpadu, inkuiri terbimbing, keterampilan proses sains, danalat pendengaran manusia.ABSTRACTThis research aimed: 1) to examine the characteristics of the guided inquirybasedintegrated Natural Science module to Increase the students science process skillswith the theme of human hearing tool, which can be used as the learning source of injunior high school students; 2) to examine the feasibility of the guided inquiry-basedintegrated Natural Science modules to Increase students' science process; 3) to examinethe effectiveness of the guided inquiry-based integrated Natural Science module toIncrease the students’ science process skills.The Research on the development of the guided inquiry-based integrated NaturalScience module used the procedure model of the Borg and Gall, which was modifiedinto seven phases, namely: 1) research and information collecting, 2) planning, 3)develop preliminary from of product, 4) preliminary field testing, 5) main productrevision, 6) main field testing, 7) final product revision. The feasibility of module wasvalidated by development module experts, materials specialists, expert design andlegibility, a science teacher (practitioner), and students. The data collection wasconducted using questionnaire, observation sheet, interview and test. During thedevelopment the data of research were analyzed by using the descriptive model ofanalysis, the feasibility of the developed module was analyzed based on the scores ofcriteria. Science process skills were analyzed using t-test (t-test) with design posttestonly control group design.The result of research, the following conclusions could be drawn: 1) thedevelopment of the guided inquiry-based integrated Natural Science module with thetheme of human hearing tool which has been developed has the followingcharacteristics: a) the module is intact, stand-alone; b) the integrated Natural Sciencematerial is holistic, meaningful, and active in nature with the guided inquiry-basedlearning syntax to increase the science process skills. How to use the formulationdevelopment procedure adapted from Borg & Gall development,2) the developedintegrated Natural Science eligible to apply to the theme of human hearing tool. Thefeasibility of the guided inquiry-based integrated Natural Science module on theassessment of experts, practitioner, and student response, overall, provided very goodcategory in development product, 3) the guided inquiry-based integrated NaturalScience module with the theme of human hearing tool is effective to increase thestudents’ science process skills (sig. 0.000) and cognitive learning outcomes (sig.0.000). The magnitude of the increase seen from gain score students' science processskills 0.38 (moderate) and cognitive learning outcomes gain score of 0.42 (moderate).Keywords: Integrated Natural Science Module, guided inquiry, science process skills,and human hearing tool.
