Penelitian ini bertujuan untuk meningkatkan hasil belajar IPA pada materi sumber daya alam dengan menerapkan model contextual teaching and learning (CTL) di kelas IV SDN 005 Peso. Penelitian ini menggunakan Penelitian Tindakan Kelas (PTK) dilaksanakan dalam 2 siklus, masing-masing terdiri dari 4 tahapan yaitu perencanaan, pelaksanaan tindakan, observasi/pengamatan dan refleksi. Data dikumpulkan dengan menggunakan teknik tes dan non tes yang meliputi tes hasil belajar siswa, lembar pengamatan aktiitas guru, lembar pengamatan psikomotorik, dan lembar pengamatan afektif. Teknik analisis data berupa teknik analisis secara kuantitatif dan kualitatif.
Rata-rata hasil belajar pada aspek kognitif meningkat dari siklus I ke siklus II. Hasil ketuntasan pada siklus I memperoleh persentase sebesar 54,54% dengan rincian 6 siswa tuntas dan 5 siswa tidak tuntas, sedangkan siklus II mencapai ketuntasan 81,81% dengan rincian 9 siswa tuntas dan 2 tidak tuntas. Hasil penelitian pada siklus II telah memenuhi lebih dari indikator keberhasilan tindakan yang telah di tetapkan yakni 75%.
Kesimpulan Penelitian Tindakan Kelas (PTK) ini adalah penerapan model contextual teaching and learning (CTL) pada materi sumber daya alam di kelas IV SDN 005 Peso dapat meningkatkan hasil belajar siswa.

This research aimed at improving the natural science learning achievement on natural resources by applying contextual teaching and learning (CTL) model at class IV of SDN 005 Peso. This research amployed classroom action research (CAR) which was carried out into two cycles in which each cycle consisted of four stage, namely: planning, implementation, observation, and reflection. The data were collected by using tes and non tes technique including achievement test, observation sheet of teacher activities, observation sheet of psycomotoric aspect, and observation of affective aspect. The data were than analyzed using quantitative and qualitative. The average score on the cognitive aspects of learning outcomes increased from cycle I to cycle II. Results of completeness in the first cycle to obtain a percentage of 54,54% with details of 6 students and 5 students completed incomplete, while the second cycle achieve mastery of 81,81% with details of 9 students completed and 2 incomplete. Results of research on the second cycle have met more than indicators of success of the action that has been set that is 75%. Conclusion Class Action Research (PTK) is the application of contextual models of teaching and learning (CTL) on the matter of natural resources in class IV SDN 005 Peso can improve student learning outcomes.
