ABSTRAKTujuan penelitian adalah (1) memperoleh gambaran pelaksanaanpembelajaran di SDIT Al Huda Wonogiri, (2) menemukan prosedur pengembanganproduk multimedia pembelajaran interaktif yang tepat, (3) menemukan multimediapembelajaran interaktif yang dikembangkan dengan software Lectora, (4)memperoleh keefektifan multimedia pembelajaran interaktif dalam meningkatkanmotivasi dan prestasi belajar IPA siswa.Pendekatan penelitian yang digunakan adalah penelitian Research andDevelopment (R&D). Populasi penelitian adalah siswa kelas 4 di SDIT Al HudaWonogiri dan SDIT Al Huda Sidoharjo. Model pengembangan mengadopsi dariADDIE (Analysis, Design, Development, Implementation, Evaluation). Teknikanalisis data menggunakan uji t. Instrumen penelitian yang digunakan adalahkuesioner dan tes. Kuesioner untuk mengukur motivasi dan tes digunakan untukmengukur prestasi siswa.Tahap uji coba produk multimedia dilakukan sebanyak tiga kali (uji one toone, uji kelompok kecil, uji kelompok besar). Hasil uji coba produk menghasilkankesimpulan bahwa penggunaan multimedia pembelajaran interaktif mampumeningkatkan motivasi dan prestasi belajar siswa.Implementasi produk dilakukan di dua sekolah yaitu SDIT Al HudaWonogiri dan SDIT Al Huda sidoharjo. Hasilnya adalah : (1) di SDIT Al HudaWonogiri hasil uji t terhadap prestasi menunjukkan nilai sig 2-tailed = 0,023 < a =5%, sehingga pengaruh produk dalam meningkatkan prestasi adalah signifikan.Pada motivasi siswa diperoleh sig 2-tailed = 0,003 < a = 5%, sehingga pengaruhproduk multimedia interaktif dalam meningkatkan motivasi adalah signifikan. (2) diSDIT Al Huda Sidoharjo hasil uji t terhadap prestasi menunjukkan nilai sig 2-tailed= 0,005 < a = 5%, sehingga pengaruh produk dalam meningkatkan prestasi adalahsignifikan. Pada motivasi siswa diperoleh sig 2-tailed = 0,038 < a = 5%, sehinggapengaruh produk dalam meningkatkan motivasi adalah signifikan.Kata kunci : Multimedia pembelajaran interaktif, Lectora, IPA, prestasi, motivasi.ABSTRACTThe objectives of this research are to obtain: (1) the description of learningimplementation at Al Huda Integrated Islamic Primary School of Wonogiri; (2) theprocedure for development of an appropriate interactive learning multimediaproduct; (3) the feasibility of interactive learning multimedia developed with theLectora software; and (4) the effectiveness of the interactive learning in improvingthe learning motivation and achievement in Nuatural Science learning of thestudents.This researcch used the Research and Development (R&D) researchmethod. Its population was all of the students in Grade 4 of Al Huda IntegratedIslamic Primary School of Wonogiri and of Al Huda Integrated Islamic PrimarySchool of Sidoharjo. The developmental model adopted the model of ADDIE(Analysis, Design, Development, Implementation, Evaluation). The data ofresearch were collected through questionnaire and test. The former was employedto measure the learning motivation of the students, and the latter was used tomeasure the learning achievement of the students. They were analyzed by using thet test. In multimedia product testing stage, three tests were administered (one to onetesting, small group testing, and large group testing). The product testing showedthat the use of interactive learning mutlimedia was able to improve the learningmotivation and achievdment of the students. The implementation of developedproducts was done at two Primary Schools, namely: Al Huda Integrated IslamicPrimary School of Wonogiri and Al Huda Integrated Islamic Primary School ofSidoharjo.The results of research are as follows: 1) At Al Huda Integrated IslamicPrimary School of Wonogiri, the result of t test indicates the value of sig 2-tailed =0.023 < a = 5%, suggesting that the effect of product in improving the learningachievement is significant. In term of learning motivation of the students the valueof sig 2-tailed is 0.003 < a = 5%, indicating that the effect of interactivemultimedia product in improving the learning motivation is significant. 2) At AlHuda Integrated Islamic Primary School of Sidoharjo, the result of t test shows thevalue of sig 2-tailed = 0,005 < a = 5%, so that the effect product in improving thelearning achievement is significant. In term of learning motivation of the students,the value of sig 2-tailed is 0.038 < a = 5%, meaning that the effect of product inimproving the learning motivation of the students is significant.Keywords: Interactive learning multimedia, Lectora, Natural Science, achievement,and motivation
