PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) UNTUK MENINGKATKAN AKTIVITAS DAN HASIL BELAJAR SISWA PADA MATA PELAJARAN GEOGRAFI KELAS X SMAN 1 SUMBERREJO BOJONEGORO

APPLICATION OF THE PROBLEM BASED LEARNING (PBL) LEARNING MODEL TO INCREASE STUDENT ACTIVITY AND LEARNING OUTCOMES IN GEOGRAPHY CLASS X SMAN 1 SUMBERREJO BOJONEGORO

Pembelajaran geografi yang telah dilaksanakan di SMA Negeri 1 Sumberrejo Bojonegoro di kelas X belum mencerminkan konsep pendidikan abad 21, seperti membimbing kemampuan aktif dan kritis siswa, kemampuan menyelesaikan masalah, berkomunikasi, dan bekerja sama. Persentase observasi aktivitas siswa awal (25%), disebabkan oleh kurangnya siswa dalam berinteraksi, serta kurang berpartisipasi aktif dalam pembelajaran. Siswa lebih sering bermain ponsel sendiri, berbicara sendiri, dan mengganggu temannya. Tujuan penelitian untuk mengetahui aktivitas siswa dan hasil belajar siswa, dalam kompetensi dasar (KD) dinamika atmosfer dan dampaknya bagi kehidupan setelah penerapan model pembelajaran problem based learning.

Jenis penelitian ini merupakan deskriptif kuantitatif, menggunakan metode pre eksperiment design one group pretes-postes. Sampel penelitian mengambil kelas X IPS 3 SMA Negeri 1 Sumberrejo Bojonegoro 2021/2022. Teknik pengumpulan data penelitian ini menggunakan lembar observasi aktivitas siswa, tes hasil belajar, dan dokumentasi. Teknik analisis data yang digunakan adalah analisis data aktivitas belajar siswa, menghitung n-gain score aktivitas siswa, uji rata-rata sampel berpasangan aktivitas siswa, dan menganalisis nilai tes dari hasil belajar.

Hasil penelitian menunjukkan keberhasilan eksperimen problem based learning, diketahui dari peningkatan aktivitas siswa. Pra eksperimen aktivitas positif diangka 25%, setelah eksperimen aktivitas positif diangka 67%. Pra eksperimen aktivitas negatif diangka 16%, setelah eksperimen aktivitas negatif diangka 14%. Perbandingan aktivitas positif naik 42%, sedangkan aktivitas negatif mengalami penurunan 2%. Aktivitas positif berada pada kategori baik (B), sedangkan aktivitas negatif kategori cukup (C). Pembagian skor n-gain didapatkan 0,3 dalam kategori sedang. Hasil uji normalitas berdistribusi normal (terima H0), karena p value 0,509 > alfa 0,05 dapat dilanjutkan uji rata-rata 2 sampel berpasangan. Hasil uji sampel T berpasangan didapatkan nilai p value 0.002 < alfa 0.05 sehingga (H0 ditolak). H1 = terdapat perbedaan antara sebelum dan sesudah eksperimen. Hasil belajar siswa dari nilai rata-rata kelas diangka 76,1. Nilai tertinggi diangka 84, sedangkan nilai terendah di angka 36. Persentase ketuntasan kelas diangka 69%.

The geography learning that has been carried out at SMA Negeri 1 Sumberrejo Bojonegoro in class X has not reflected the concept of 21st century education, such as guiding students' active and critical abilities, problem solving skills, communication, and collaboration. The percentage of early student activity observations (25%), caused by the lack of students in interacting, and not actively participating in learning. Students more often play their own cellphones, talk to themselves, and annoy their friends. The purpose of the study was to determine student activities and student learning outcomes, in the basic competencies of atmospheric dynamics and their impact on life after the application of the problem based learning model.

This type of research is a quantitative descriptive, using a pre-experimental design one group pretest-posttest method. The research sample took class X IPS 3 at SMA Negeri 1 Sumberrejo Bojonegoro 2021/2022. The data collection technique in this study used student activity observation sheets, learning outcomes tests, and documentation. The data analysis technique used is data analysis of student learning activities, calculating the n-gain score of student activities, testing the average paired sample of student activities, and analyzing test scores from learning outcomes.

The results showed the success of the problem based learning experiment, it was known from the increase in student activity. Pre-experimental positive activity is 25%, after experimental positive activity is 67%. Pre-experiment negative activity is 16%, after experiment negative activity is 14%. The ratio of positive activities increased by 42%, while negative activities decreased by 2%. Positive activities are in good category (B), while negative activities are in sufficient category (C). The distribution of the n-gain score was 0.3 in the medium category. The results of the normality test are normally distributed (accept H0), because p value 0.509 > alpha 0.05, it can be continued to test the average of 2 paired samples. The results of the paired T sample test obtained a p value of 0.002 < alpha 0.05 so that (H0 is rejected). H1 = there is a difference between before and after the experiment. Student learning outcomes from the average value of the class is 76.1. The highest score is 84, while the lowest value is 36. The percentage of class completeness is 69%.
