Abstract

This study aimed to determine the effect of the Project-Based Learning (PjBL) model on students' cognitive, affective, and psychomotor learning outcomes in learning prokaryotic material. The research was conducted at SMA Kesatrian 2 Semarang using a quasi-experimental method with a nonequivalent control group design. The final sample consisted of 25 students in the experimental class and 29 students in the control class, selected through purposive sampling. The research instruments included cognitive learning outcome tests, affective observation sheets, and psychomotor observation sheets. Data were analyzed using the Shapiro–Wilk normality test, Levene's homogeneity test, the Mann–Whitney U test, the independent samples t-test, and the N-Gain test. The results showed a significant difference in cognitive learning outcomes (p < 0.001) and affective learning outcomes (p = 0.044) between the experimental and control groups. However, no significant difference was found in psychomotor learning outcomes (p = 0.282). The average N-Gain scores were 0.63 for the experimental group and 0.69 for the control group, both categorized as moderate. Because the two groups differed significantly in their initial abilities before the intervention, the findings should be interpreted with caution.

Abstract

Penelitian ini bertujuan untuk mengetahui penggunaan tutup botol yang tepat pada pertumbuhan anggrek Dendrobium donny rizal antara penggunaan tutup botol filter dengan tutup botol rapat. Sampel penelitian terdiri dari 30 planlet anggrek D. donny rizal dengan diambil 5 planlet sebagai satuan pengukuran. Data tersebut diolah dengan menggunakan metode Rancangan Acak Lengkap (RAL) dengan satu faktor perlakuan yaitu tutup filter dan tutup rapat. Terdapat 2 perlakuan dengan 6 kali ulangan. Data penelitian diambil dengan teknik pengamatan dan pengukuran objek secara langsung dengan cara mengukur dan menghitung objek sesuai dengan parameter yang diamati. Data dianalisis dengan uji-t independent dengan taraf kepercayaan 5%. Hasil penelitian menunjukkan bahwa jenis tutup botol kultur berpengaruh terhadap semua parameter pertumbuhan vegetatif anggrek D. donny rizal. Planlet yang ditanam dengan tutup botol berfilter mempunyai ukuran  tinggi tanaman, pertumbuhan akar, dan pertumbuhan daun yang lebih besar dibandingkan dengan planlet yang ditanam di tutup botol rapat. Hal ini dikarenakan pada penggunaan tutup botol berfilter terjadi pergantian udara dari dan ke dalam botol kultur yang berpengaruh pada peningkatan laju proses fotosintesis
