%X Students today face the challenge of modern technological advancements in the Era
of the Fourth Industrial Revolution. Students are less involved in forming their own
knowledge by developing logical thinking that includes understanding concepts,
facts, and then translating them into a product. That characteristic encompasses
the scope of science process skills. In fulfilling students' science process skills, an
appropriate project-based learning model is needed, and the solution is to
implement the Project Based Learning (PJBL) model with a STEM approach.
(Science, Technology, Engineering, and Mathematics). This research aims to
determine the differences in learning outcomes before and after implementing
PjBL-STEM to stimulate students' science process skills in reaction rate material.
The research design used is a Quasi-Experimental design (pseudo-experiment) with
a one group pre-test-post-test design type. The research sample consisted of 30
students from the XI IPA 1 class at MAN 2 Cilegon, selected using the Purposive
Sampling technique. The instruments used include LKPD, Teaching Modules,
observation sheets for science process skills, and test questions. Data analysis
techniques based on descriptive statistical analysis (results of test instruments and
observation of students' science process skills) and inferential statistical analysis
(uji normalitas, paired sample t-test, reliabilitas, validitas. The results show that
science process skills are stimulated by the PJBL-STEM model as evidenced by the
sign value. (2-tailed) of 0.000 < 0.05 and significant differences in learning
outcomes from tests and observations. The Science Process Skills from observations
were stimulated with an average of 91% across 10 indicators, which falls into the
very good category.

%O Peserta didik saat ini menghadapi tantangan kemajuan teknologi modern pada Era
Revolusi Industri 4.0. Peserta didik kurang dilibatkan dalam membentuk
pengetahuan sendiri dalam membangun cara berpikir secara logis yang memuat
tentang pemahaman konsep, fakta-fakta lalu menuangkannya dalam suatu produk.
Karakter tersebut merupakan cakupan dari keterampilan proses sains. Dalam
memenuhi keterampilan proses sains siswa dibutuhkan model pembelajaran yang
tepat untuk berbasis proyek, solusinya dengan menerapkan model Project Based
Learning (PJBL) dengan pendekatan STEM (Science, Technology, Engineering,
and Mathematics). Penelitian ini bertujuan untuk mengetahui perbedaan hasil
belajar sebelum dan sesudah diterapkan enerapan PjBL-STEM untuk menstimulus
keterampilan proses sains siswa pada materi laju reaksi. Desain penelitian yang
digunakan adalah Quasy Eksperimental design (eksperimen semu) dengan jenis
one group pre test-post test design. Sampel penelitiannya adalah siswa-siswi kelas
XI IPA 1 di MAN 2 Cilegon sebanyak 30 orang dengan teknik Purposive
Sampling. Instrumen yang digunakan seperti LKPD, Modul Ajar, lembar
observasi keterampilan proses sains dan soal tes. Teknik analisis data berdasarkan
analisis statistik deskriptif (hasil instrumen tes dan observasi keterampilan proses
sains siswa) dan analisis statistik inferensial (uji normalitas, paired sample t-test,
reliabilitas, validitas). Hasil menunjukkan bahwa keterampilan proses sains
terstimulus dengan model PJBL-STEM yang dibuktikan dengan nilai sign. (2-
tailed) sebesar 0,000 < 0,05 serta perbedaan hasil belajar dari tes dan observasi
yang signifikan. Keterampilan Proses Sains dari observasi terstimulus dengan
rata-rata dari 10 indikator sebesar 91% yang berada pada kategori sangat baik.
