ABSTRAK Penelitian ini bertujuan untuk mengembangkan kit praktikum Elektronika Dasar II berbasis simulator Proteus untuk meningkatkan kemampuan pemecahan masalah mahasiswa.Hasil observasi dalam prapenelitian menunjukkan bahwa mahasiswa kesulitan merangkai komponen elektronika, kekurangan waktu praktikum, dan kesulitan dalam mendapatkan data.Untuk mengatasi permasalahan ini dilakukan pengembangan kit praktikum Elektronika Dasar IIberbasis menggunakan simulator Proteus. Melalui kit praktikum mahasiswa fokus pada proses pengambilan data dan menganalisis sinyal keluaran rangkaian elektronika.Sedangkan simulator Proteus dapat membantu dalam mengamati gejala-gejala yang tidak dapat diamati langsung dan sebagai data pembanding. Penelitian ini merupakan jenis penelitian dan pengembangan dengan tahapan adalah analisis kebutuhan, pengembangan produk awal, validasi ahli, uji lapangan dan revisi produk. Penelitian ini dilakukan di Laboratorium Fisika FMIPA Universitas Bengkulu semester ganjil 2018/2019dengan subyek penelitian ini adalah 22 mahasiswa. Pengumpulan data dilakukan menggunakan metode observasi dan kuesioner yang dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa kit praktikum yang berhasil dikembangkan terdiri dari delapan percobaan yaitu penguat common drain, common source, emitor ditanahkan, pushpull, respon frekuensi rendah, inverting dan non inverting, integrator dan diferensiator, dan filter aktif. Kelayakan kit praktikum sebagai media pembelajaran di laboratorium berdasarkan validasi ahli sebesar 82,50% (sangat layak) dan berdasarkan pengguna sebesar 82, 64% (sangat layak).

The results of observations in the pre-study showed that students had difficulty assembling electronic components, lack of practicum time, and difficulties in obtaining data. To overcome this problem, the development of Basic Electronics II based practicum kit using the Proteus simulator is carried out. Through the practicum kit students focus on the process of data retrieval and analyzing the electronic circuit output signal. Whereas the Proteus simulator can help in observing symptoms that cannot be observed directly and as comparative data. This research is a type of research and development with stages are needs analysis, initial product development, expert validation, field testing and product revision. This research was conducted in the Physics Laboratory of the University of Bengkulu FMIPA odd semester 2018/2019 with the subjects of this study were 22 students. Data collection was carried out using observation methods and questionnaires which were analyzed quantitatively descriptively. The results showed that the practicum kit that was successfully developed consisted of eight experiments namely common drain amplifier, common source, ground emitter, pushpull, low frequency response, inverting and non-inverting, integrators and differentiators, and active filters. The feasibility of the practicum kit as a learning media in a laboratory based on expert validation is 82.50% (very feasible) and based on the user is 82, 64% (very feasible).
