Abstract

Pembelajaran kimia yang berbasis pada masalah (PBL) melibatkan aktivitas-aktivitas sains dalam proses perolehan pengetahuan dan pengembangan kemampuan berpikir pada peserta didik sehingga adanya laboratorium diperlukan sebagai sarana pembelajaran. Akan tetapi, sarana laboratorium sebagai pendukung aktivitas proses sains peserta didik terkadang belum dapat dimanfatkan secara optimal baik karena keterbatasan alat maupun biaya. Selain itu, pembelajaran kimia pada pendidikan formal umumnya belum terintegrasi secara optimal dengan cabang ilmu lain sehingga diperlukan suatu pendekatan pembelajaran terintegrasi yang berbasis laboratorium. Penelitian ini bertujuan untuk mengembangkan media pembelajaran untuk pembelajaran berbasis STEM berupa sistem pendeteksi gas karbon dioksida (CO2) yang dilengkapi dengan modul interaktif STEM. Penelitian ini diawali dengan pembuatan modul dan sistem pendeteksi gas CO2 yang tersusun atas sensor berbahan oksida logam semikonduktor SnO2, CDM 4160. Sistem pendeteksi gas dikalibrasi dengan menggunakan flowmeter. Media pembelajaran STEM divalidasi dan diimplementasikan pada pembelajaran kimia SMA/SMK. Uji coba lapangan dilakukan pada siswa kelas X SMK untuk kelas eksperimen dan kontrol. Media yang dikembangkan pembelajaran sistem pendeteksi gas CO2 yang terintegrasi dengan bidang ilmu fisika, matematika, dan teknologi informasi. Hasil penelitian menunjukkan bahwa sistem pendeteksi gas CO2 yang telah divalidasi oleh 3 dosen kimia dan 2 guru kimia SMA/SMK layak untuk digunakan sebagai media pembelajaran kimia terintegrasi berbasis STEM, dengan skor kelayakan sistem pendeteksi gas CO2 sebesar 3,42 dan modul interaktif STEM sebesar 3,33. Uji coba lapangan dilakukan pada 33 siswa kelas eksperimen dan 33 siswa kelas kontrol di SMKN 5 Surabaya. Berdasarkan hasil uji coba lapangan, terdapat perbedaan hasil belajar yang signifikan baik pada aspek kognitif, afektif, dan psikomotor. ================================================================================================ Learning chemistry based on the problem (PBL) involves scientific activities in the process of acquisition of knowledge and the development of thinking skills in learners so that laboratory is necessary as a learning tool. Yet, laboratory instruments to support science activities sometimes have not been optimally used because of limited equipment and costs. In addition, chemistry learning in formal education have not been optimally integrated with other disciplines so that it is necessary to apply integrated laboratory-based in chemistry learning. This study aims to develop a mini-scale laboratory equipment for STEM based learning in the form of carbon dioxide (CO2) detection system which is equipped with an interactive STEM module as chemistry learning media. This research begun with the fabricating of carbon dioxide detection system which was composed of semiconductor SnO2 based sensor, CDM 4160. Carbon dioxide gas detection system was calibrated by using flowmeter. STEM instructional media was validated and implemented in chemistry learning for high or vocational school. Field trial conducted on state vocational school students in grade X on experimental and control group. Learning media which was developed integrated with physics, mathematics, and technology information. Results of this research showed that CO2 detection system and interactive STEM interactive module which was validated by 3 lecturers and 2 chemistry teachers is valid to be used as STEM chemistry learning media, with the validity score of CO2 detection system 3,42 and STEM interactive module 3,33. Field trial was done on 33 students of experimental group and 33 students of control group in State Vocational High School 5 Surabaya. Based on the result of field trial could be concluded that there was a significant difference in students learning outcome on cognitive, affective, and psychomotoric aspect between experimental and control group.
