Abstract :
Minat belajar belajar fisika masih rendah salah satu meningkatkan minat belajar fisika pada
siswa dapat dicapai dengan cara mengembangkan alat peraga. Penelitian ini mengunakan
motode Research and Development dengan model 4D Difine dengan langkah-langkah:
(analisis kurikulum, analisis konsep,analisis kebutuhan siswa, dan analisis kegiatan
pembelajaran) Design memiliki langkah langkah (pemilihan komponen bahan, desain alat
peraga, validasi alat, dan perakitan prototipe. Development (validasi prototipe, pengembangan
prototipe produk, uji coba terbatas, dan pengembangan produk akhir). Dan tahap akhir, yaitu
penyebaran (Disseminate), dilaksanakan pada uji coba lapangan di sekolah. Penelitian ini
bertujuan untuk merancang dan mengembangkan alat peraga berupa lampu otomatis berbasis
Arduino Uno sebagai upaya untuk meningkatkan minat belajar fisika. Subjek penelitian ini
adalah siswa kelas XII IPA di SMA Negeri 72 Jakarta pada semester ganjil tahun ajaran
2023/2024. Hasil penilaian validator terhadap alat peraga yang dikembangkan menunjukkan
persentase kelayakan sebesar 79,48% pada kategori "layak".sehingga alat peraga lampu
otomatis berbasis Arduino Uno tersebut dinyatakan memenuhi syarat untuk dapat digunakan
disekolah tersebut. Hasil pengujian produk alat peraga ?Lampu Otomatis Berbasis Arduino
Uno? pada uji coba terbatas dari mahasiswa mendapatkan respon positif sebesar 75,57%
kategori ?praktis dengan uji lapangan 80% kategori ?sangat praktis?. Peningkatan minat belajar
siswa diukur menggunakan angket yang diberikan sebelum dan sesudah kegiatan berlangsung,
data akan dihitung menggunakan microsoft Excel untuk menentukan nilai N-gain. kemudian
didapati N-gain sebesar 0,71 pada kriteria ?tinggi?. Dengan demikian alat peraga ini dapat
digunakan untuk memperbesar minat siswa terhadap pelajaran fisika.

physics in students can be achieved by developing teaching aids. This research uses the
Research and Development method with the 4D Define model with steps: (curriculum analysis,
concept analysis, analysis of student needs, and analysis of learning activities) Design has
steps (selection of material components, design of teaching aids, validation of tools, and
assembly of prototypes. Development (prototype validation, product prototype development,
limited trials, and final product development). And the final stage, namely Disseminate, was
carried out on field trials at school. This research aims to design and develop teaching aids in
the form of Arduino Uno-based automatic lights as an effort to increase interest in learning
physics. The subjects of this research were XII science students at SMA Negeri 72 Jakarta in
the odd semester of the 2023/2024 academic year. The results of the validator's assessment of
the developed teaching aids showed a feasibility percentage of 79.48% in the ?feasible?
category, so that the Arduino Uno-based automatic light props were declared eligible for use
at the school. The results of testing the ?Arduino Uno-based Automatic Light? props product in
the limited trial from students received a positive response of 75.57% in the ?practical?
category with a field test of 80% in the ?very practical? category. The increase in student
interest in learning is measured using a questionnaire given before and after the activity takes
place, the data will be calculated using Microsoft Excel to determine the N-gain value. then
obtained an N-gain of 0.71 in the ?high? criteria. Thus, this teaching aid can be used to increase
students' interest in physics lessons.
