Pengaruh Model Pembelajaran Project Based-Learning (PjBL) Terhadap Hasil Belajar IPA Materi Tumbuhan sebagai Makhluk Hidup Siswa Tunarungu di SLB Bangun Bangsa Surabaya

The Influence of The Project Based-Learning (PjBL) Learning Model on Science Learning Outcomes of Plant Needs Material As Living Things For Deaf Students at SLB Bangun Bangsa Surabaya

Penelitian ini dilatarbelakangi oleh hasil observasi berupa permasalahan siswa tunarugu terkait hasil belajar pada mata pelajaran IPA, khususnya materi kebutuhan tumbuhan sebagai makhluk hidup. Dalam penelitian ini hasil belajar siswa tunarungu ditingkatkan melalui penggunaan model pembelajaran Project Based Learning (PjBL). Tujuan penelitian ini untuk mengetahui ada tidaknya pengaruh signifikan model pembelajaran Project Based Leraning (PjBL) terhadap hasil belajar IPA siswa tunarungu. Subjek yang diteliti berjumlah 6 siswa tunarungu kelas IV di SLB Bangun Bangsa Surabaya. Metode penelitian yang digunakan yaitu pendekatan kuantitatif dengan desain pre-experimental tipe design one group pre-test pos-test. Teknik statistic yang digunakan dalam analisis data adalah perhitungan menggunakan rumus Wilcoxon match pair test dan pengujian melalui aplikasi SPSS v.26.0. Hasil penelitian menunjukkan nilai rata-rata sebelum diberikan perlakukan sebesar 37,5 dan meningkat menjadi 72,9 setelah diberi perlakukan. Dari pengujian statistic Wilcoxon secara manual diperoleh hasil  Ztabel = 1,96 < Zhitung = 2,20 dan pada uji Wilcoxon menggunakan aplikasi SPSS diperoleh hasil  Asymp. Sig. (2-tailed) 0,027 < 0,05 sehingga diperoleh hasil yang sama yaitu H0 ditolak dan diterimanya Ha. Dari hasil analisis data melalui kedua cara tersebut dan disimpulkan bahwa  ada pengaruh signifikan penerapan PjBL terhadap hasil belajar IPA siswa tunarungu di SLB Bangun Bangsa Surabaya.

This research was motivated by observations in the form of deaf students’s problems which are related to learning outcomes in science subjects, especially the material plant needs as living things. In this study, the learning outcomes of deaf students were improved through the use of the Project Based Learning (PjBL) model. The purpose of this study was to determine whether there was a significant influence of the Project Based Learning (PjBL)  model on the science learning outcomes of deaf students. The subjects studied were 6 grade IV deaf students at SLB Bangun Bangsa Surabaya. The research method used is a quantitative approach with a pre-experimental design type one group pre-test pos-test design. The statistical technique used in data analysis is the Wilcoxon match pair test. The statistical techniques used in data analysis are calculations using the Wilcoxon match pair test formula and testing through the SPSS v.26.0 application. The results showed an average score before being given treatment of 37.5 and increased to 72.9 after being given treatment. From statistical testing using the Wilcoxon formula manually, Ztabel = 1.96 < Zcalculate = 2.20 and in the Wilcoxon test using the SPSS application, Asymp results were obtained. Sig. (2-tailed) 0.027 < 0.05 so that the same result is obtained. meaning that H0 is rejected and Ha is accepted. From the results of data analysis through these two methods and it was concluded that there was a significant influence on the application of PjBL on the learning outcomes of deaf students at SLB Bangun Bangsa Surabaya.
