ABSTRAKPenelitian ini bertujuan untuk mengetahui: 1) pengembangan modul IPATerpadu SMP/MTs Kelas VII dengan model Discovery Learning tema Air LimbahIndustri Batik; 2) kelayakan modul IPA Terpadu SMP/MTs Kelas VII dengan modelDiscovery Learning tema Air Limbah Industri Batik; 3) efektivitas modul IPA TerpaduSMP/MTs Kelas VII dengan model Discovery Learning tema Air Limbah Industri Batikdalam meningkatkan keterampilan proses sains.Penelitian pengembangan modul IPA Terpadu ini dilakukan mengikuti model R& D dari Thiagarajan (1974) yang terdiri dari 4 tahapan, yaitu pendefinisian (define),perancangan (design), pengembangan (develop), dan penyebaran (disseminate). Semuatahapan tersebut telah dilakukan sehingga data yang diperoleh dianalisis lebih lanjut.Desain penelitian yang digunakan adalah Quasi Experimental Design dengan modelNonequivalent Control Group Design. Pada desain penelitian ini terdapat pretestsebelum diberi perlakuan dan posttest setelah diberi perlakuan. Analisis data yangdigunakan selama pengembangan adalah analisis deskriptif, analisis kelayakan modulberdasarkan skor kriteria, dan analisis tes keterampilan proses sains, sikap danpsikomotor melalui n-gain score dari hasil pretest dan posttest tiap kelompok dan t-test.Hasil penelitian disimpulkan bahwa: 1) modul IPA terpadu SMP/MTs berbasispenemuan (discovery learning) tema air limbah industri batik yang dikembangkandengan model Four D (4D). Perancangan dan pengembangan modul mengacu padasintak discovery learning. Kegiatan pembelajaran dalam modul sesuai dengan sintakdiscovery learning untuk meningkatkan keterampilan proses sains siswa; 2) modul IPAterpadu SMP/MTs berbasis penemuan (discovery learning) tema air limbah industri batikyang dikembangkan termasuk dalam kategori sangat baik ditinjau dari kelayakan fisik,isi/materi, bahasa, media, dan penyajian, kesesuaian model penemuan dalammemberdayaan keterampilan proses sains siswa, kesesuaian basis discovery learning,kualitas metode penyajian, penggunaan ilustrasi, kelengkapan bahan penunjang,penyajian pembelajaran, kegrafikan, dan tampilan umum berdasarkan validator ahli danpraktisi pendidikan serta menurut siswa; 3) modul IPA terpadu SMP/MTs berbasispenemuan (discovery learning) tema air limbah industri batik yang dikembangkan efektifmeningkatkan keterampilan proses sains berdasarkan hasil N-gain score sebesar 0,32termasuk kriteria sedang.Kata kunci: modul IPA Terpadu, discovery learning, keterampilan proses sains, airlimbah industri batikABSTRACTThe research aims to know: (1) the development of the Discovery Learning-Based Integrated Natural Science Module to increase the students’ science process skillswith the theme of Batik Industries Waste Water, which can be used as the learningsource of 7th Class the students at Junior Secondary School; (2) the feasibility of theDiscovery Learning-Based Integrated Natural Science Module to improve the students’science process skills with the theme of Batik Industrial Waste Water; (3) theeffectiveness of the Discovery Learning-Based Integrated Natural Science Module toimprove the students’s science process skills with the theme of Batik Industrial WasteWater.The research on the development of the Discovery Learning-Based IntegratedNatural Science Module used the procedure claimed R & D by Thiagarajan (1974) into 4phases, namely: 1) define, 2) design, 3) develop, and 4) disseminate. Researh design usedQuasi Experimental Design with model Nonequivalent Control Group Design. Duringthe development 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, and the science process skill test, pschicomotor was analyzed by using N-gainscore from pretest and posttest and the t-test.The results of research are concluded: 1) the Discovery Learning-BasedIntegrated Natural Science Module with the theme of Batik Industrial Waste Waterwhich has been developed with Four D (4D) models. Design and development of modulerefer to discovery learning syntax. Learning activity in module accordance syntaxdiscovery learning to increase the science process skills. 2) integrated Natural Sciencemodule based discovery learning the theme of batik industrial waste water included inthe excellent category in terms of eligibility physical, content/material, language, media,and presentation, suitability model of the invention in the empowerment of scienceprocess skills students, suitability base discovery learning, the quality of the method ofpresentation, use of illustrations, the completeness of supporting materials, instructionalpresentation, graphic, and general appearance based validator experts and practitioners aswell as by students. 3) integrated Natural Science module based discovery learning thetheme of batik industrial waste water developed effectively increase science processskills based on the N-gain score of 0.32 including moderate category.Keywords: Integrated Natural Science module, discovery learning, science processskills, and batik industrial waste water.
