Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran Project Based Learning (PjBL) melalui proyek fisik individu membuat robot penyaring sampah terhadap kemampuan berpikir kreatif peserta didik pada mata pelajaran IPAS materi Harmoni dalam Ekosistem di kelas V SDIT Tresna Asih Bandar Lampung. Jenis penelitian yang digunakan adalah eksperimen semu (QuasiExperimental Design) dengan bentuk Nonequivalent Control Group Design. Populasi penelitian mencakup seluruh peserta didik kelas V SDIT Tresna Asih. Pengambilan sampel dilakukan menggunakan teknik Purposive Sampling, sehingga terpilih kelas VA sebagai Kelas Eksperimen n=19 setelah pembersihan data outlier) dan kelas VB sebagai Kelas Kontrol n=20. Kelas Eksperimen diberikan perlakuan berupa model PjBL dengan produk individu Robot Penyaring Sampah berbahan daur ulang, sedangkan Kelas Kontrol menggunakan metode konvensional dengan produk individu berupa Poster. Instrumen pengumpulan data utama berupa tes tertulis uraian sebanyak 5 butir soal yang telah teruji validitas dan reliabilitasnya, didukung oleh instrumen penilaian produk fisik. Teknik analisis data yang digunakan meliputi uji prasyarat (normalitas Shapiro-Wilk dan homogenitas Levene's Test) serta uji hipotesis menggunakan Independent Samples T-Test melalui program SPSS. Hasil penelitian menunjukkan bahwa terdapat perbedaan peningkatan kemampuan berpikir kreatif yang signifikan antara kedua kelas. Nilai rata-rata posttest Kelas Eksperimen mencapai 66,32 dengan perolehan efektivitas Normalized Gain (N-Gain) sebesar 0,3638 (Kriteria Sedang). Capaian ini secara nyata mengungguli Kelas Kontrol yang hanya memperoleh rata-rata posttest 54,25 dengan perolehan N-Gain sebesar 0,1822 (Kriteria Rendah). Hasil uji hipotesis akhir menggunakan Independent Samples T-Test menghasilkan nilai thitung sebesar 3,010 dengan nilai signifikansi Sig. (2-tailed) sebesar 0,005. Karena nilai Sig. (2-tailed) < 0,05 ,0,005 < 0,05, maka H0 ditolak dan Ha diterima. Kesimpulan dari penelitian ini adalah penerapan model pembelajaran Project Based Learning (PjBL) berpengaruh signifikaniii dan efektif dalam meningkatkan kemampuan berpikir kreatif peserta didik kelas V di SDIT Tresna Asih Bandar Lampung. ABSTRACT The primary background of this research is the low creative thinking skills of students in solving environmental problems. This study aims to determine the effect of implementing the Project-Based Learning (PjBL) model through individual physical projects of making wastefiltering robots on students' creative thinking skills in the IPAS subject, specifically on the topic of Harmony in Ecosystems, in Grade V at SDIT Tresna Asih Bandar Lampung. This research employed a QuasiExperimental Design in the form of a Nonequivalent Control Group Design. The research population included all fifth-grade students at SDIT Tresna Asih. Sampling was conducted using a Purposive Sampling technique, selecting Grade V A as the Experimental Class n=19 after outlier data cleaning) and Grade V B as the Control Class n=20. The Experimental Class received treatment using the PjBL model with an individual recycled waste-filtering robot as the product, while the Control Class used a conventional method with an individual poster as the product. The primary data collection instrument was a written essay test consisting of 5 items that had been tested for validity and reliability, supported by physical product assessment instruments. Data analysis techniques included prerequisite tests (Shapiro-Wilk normality test and Levene's homogeneity test) and hypothesis testing using the Independent Samples T-Test via the SPSS program. The results showed a significant difference in the improvement of creative thinking skills between the two classes. The post-test mean score of the Experimental Class reached 66.32 with a Normalized Gain (N-Gain) effectiveness score of 0.3638 (Medium Criteria). This achievement significantly outperformed the Control Class, which only obtained a post-test mean score of 54.25 with an N-Gain score of 0.1822 (Low Criteria). The final hypothesis test using the Independent Samples T-Test yielded a t-value of 3.010 with a significance value of Sig. (2- tailed) of 0.005. Since the Sig. (2-tailed) value (<0.05) (0.005 < 0.05), (H0) was rejected and (Ha) was accepted. The conclusion of this study is that the implementation of the Project-Based Learning (PjBL) modelv has a significant and effective influence on improving the creative thinking skills of fifth-grade students at SDIT Tresna Asih Bandar Lampung.
