Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengatasi keterbatasan pemahaman siswa SMP terhadap konsep dasar teknologi elektronika dengan pendekatan pembelajaran berbasis pengalaman nyata dan visualisasi langsung. Urgensi pengabdian ini terletak pada kebutuhan untuk meningkatkan literasi STEM siswa di sekolah-sekolah dengan fasilitas terbatas, seperti SMP Citra Kasih Ambon. Program Teknologi Elektronika yang dilaksanakan terdiri atas dua aktivitas utama: visualisasi gelombang listrik menggunakan osiloskop dan pengenalan teknologi pencetakan tiga dimensi (3D printing). Metode pelaksanaan meliputi demonstrasi alat, praktik langsung, diskusi interaktif, dan evaluasi menggunakan pretest dan posttest. Teknik sampling yang digunakan adalah simple random sampling, dimana 25 siswa dari kelas VII hingga IX dipilih secara acak untuk mengikuti kegiatan ini. Instrumen evaluasi berupa sepuluh soal yang mengukur pemahaman konsep elektronika, fungsi osiloskop, karakteristik gelombang AC dan DC, serta prinsip kerja printer 3D. Hasil pretest menunjukkan tingkat pemahaman awal siswa yang terbatas dengan rata-rata jawaban benar sebesar 53,6%, sedangkan posttest menunjukkan peningkatan menjadi 77,2%, yang mencerminkan peningkatan pemahaman sebesar 23,6%. Selain itu, siswa menunjukkan keterlibatan aktif dan respons positif sepanjang kegiatan. Temuan ini menunjukkan bahwa pembelajaran berbasis eksperimen dan visualisasi efektif dalam meningkatkan pemahaman, motivasi, dan literasi STEM siswa SMP. Program ini direkomendasikan untuk diterapkan secara berkelanjutan melalui kolaborasi antara perguruan tinggi dan sekolah.

Abstract

Water quality in cultivating marine organisms is a very important part to pay attention to. Prevention of pollution in marine waters needs to be done by recognizing changes in physical, chemical and biological parameters in these waters from normal conditions. To find out these changes, it is necessary to carry out measurements which include parameters that determine the quality of a liquid and carry them out periodically. The measurement parameters measured include pH, Dissolved Oxygen (DO), Electrical Conductivity (EC) and temperature. The use of technological developments, especially in the world of microcontrollers, namely the ESP32 device, makes it possible to design measurement instruments in determining the quality of sea waters to be more efficient and comprehensive. The instrument created in this research will be equipped with several sensors that will read the parameters that determine water quality. The sensors used are pH sensors, DO sensors, EC sensors and temperature sensors. This research aims to create an integrated instrument (pH, DO, ED and Temperature) with instrument performance specifications that have good accuracy and a portable design so that it is easy to use in the field. The research results show thatdevelopment of a biosensor instrument for measuring seawater quality based on the ESP32 DevKit V1 can work well and can display temperature, degree of acidity (pH), DO and EC parameters on the LCD screen according to actual conditions with a difference range in percent between 0.2% - 4.16 %. The accuracy level of the designed tool is classified as having a high accuracy above 95%

Abstract

The development of digital technology demands innovation in physics learning to make it more contextual and applicable. However, in it’s implementation, learning at the Senior High School (SMA) level still faces various problems, especially in physics learning. One of the main obstacles is the abstract and mathematical nature of physics material, making it difficult for students to understand if it is only delivered through lecture methods or text-based learning. This community service activity aims to introduce Arduino microcontroller technology as a practical-based physics learning medium to improve students conceptual understanding and interest in learning. The activity implementation method is designed gradually and participatively, including preparation stages, socialization and introduction to Arduino concepts, training and physics practicum based on Arduino, as well as evaluation and follow-up. The participants consisted of 20 twelfth-grade science major students from SMA Negeri 10 Ambon. Evaluation was conducted using a questionnaire instrument to assess students perceived understanding, interest, and responses to the activity. The results showed an increase in students perceived understanding of physics concepts after the activity, with 55% categorized as “very good” and 35% as “good.” In addition, students interest and enthusiasm for Arduino-based physics learning also increased, reaching 70% in the “very good” category. These findings indicate that the use of Arduino microcontrollers is effective as an interactive and contextual physics learning medium, with the potential to improve the quality of physics education in schools.
