Penelitian ini bertujuan untuk meningkatkan hasil belajar siswa pada materi energi dan perubahannya siswa kelas iv a sdn 015 tarakan. jenis penelitian yang digunakan oleh peneliti adalah penelitian tindakan kelas (ptk). penelitian tindakan kelas (ptk) ini dilaksanakan dalam 2 siklus, masing-masing empat komponen yaitu planning (perencanaan), action (tindakan), observating (pengamatan), dan reflecting (refleksi). teknik pengumpulan data yang digunakan adalah tes dan non-tes. instrument pengumpulan data yang digunakan adalah tes hasil belajar, lembar penilaian psikomotorik siswa, lembar penilaian afektif, dan lembar observasi aktivitas siswa dalam pengolahan pembelajaran. rata-rata ketuntasan hasil belajar siswa secara klasikal pada aspek psikomotorik siklus i yaitu 86% siswa dinyatakan telah tuntas sedangkan 14% siswa tidak tuntas. mengalami peningkatan pada siklus ii yaitu 93% siswa telah dinyatakan tuntas sedangkan 7% siswa tidak tuntas. rata-rata ketuntasan hasil belajar siswa secara klasikal pada aspek afektif siklus i yaitu 82% siswa telah tuntas sedangkan 18% siswa tidak tuntas mengalami peningkatan pada siklus ii pada aspek afektif yaitu 96% siswa telah tuntas sedangkan hanya 4% siswa tidak tuntas. rata-rata ketuntasan hasil belajar siswa secara klasikal pada aspek kognitif pada siklus i yaitu siswa yang telah tuntas yaitu 61% sedangkan yang tidak tuntas yaitu 39% mengalami peningkatan pada siklus ii yaitu siswa yang tuntas 89% dan tidak tuntas yaitu 11%. berdasarkan hasil penelitian dapat disimpulkan bahwa dengan menerapkan model pembelajaran integrasi pendekatan scientifik dan metode inquiry dapat meningkatkan hasil belajar ipa pada materi energi dan perubahannya pada siswa kelas iv asdn 015 tarakan. kata kunci: ipa, hasil belajar, pendekatan scientifik, metode inquiry

The objective of this research was to improve the learning outcomes of students on the topic of energy and changes in matter at the iv a class on sdn 015 tarakan. the researcher used the classroom action research (car) as the research design. this classroom action research (car) was conducted on 2 cycles, each of them consists of planning, action, observation and reflection. the data was collected either through test or non-test. the instrument of the data that be collected was through test of learning evaluation, the sheet of students psychomotorical assessment, the sheet of emotional assesment and observation sheet of students activity in learning process. the average passing grade of the students learning outcomes, classically on the aspect of psychomotor on the first cycle found that 86% students were passing and 14% were not on the category of passing grade. it had been improved on the second cycle which found that 93% of students were categorized passed and 7% were not. the average passing grade of the students learning outcomes, classically on the aspect of emotional on the first cycle found that 82% students were categorized passed while the other 18% who categorized not passed were having improvement on the second cycle. 96% students passed and the 4% did not pass. the average passing grade of the students learning outcomes, classically on the aspect of cognitive on the first cycle found that 61% students passed and 39% students did not qualify the category but they had improvement on the second cycle. students who passed the test were about 89% while 11% did not pass the test. based on the result of this research, it may assumed that by applying the model of integrational scientific approach and inquiry method can improve the learning outcomes of science learning on the topic of energy and changes in matter of iv a students of sdn 015 tarakan. keywords: ipa, learning outcomes, scientific approach, inquiry method
