Abstract

Pengembangan e-learning melalui aplikasi educate pada materi gerak parabola ini bertujuan untuk mengetahui kelayakan media yang ditinjau dari segi validitas dan kepraktisan media. Penelitian ini menggunakan metode Penelitian dan Pengembangan (R&D) dengan mengadopsi model pengembangan 4D yang terdiri dari 4 tahapan, yaitu define, design, develop dan disseminate. Instrumen yang digunakan meliputi validasi ahli, praktikalitas guru dan praktikalitas siswa. Data yang diperoleh dianalisis dengan uji validitas dan uji praktikalitas. Hasil penelitian diperoleh validitas media e-learning melalui aplikasi educate pada materi gerak parabola yang dilihat dari nilai rerata para ahli 3,3, sehingga media yang dikembangkan dapat dikatakan valid. Kemudian, hasil praktikalitas media e-learning melalui aplikasi educate pada materi gerak parabola oleh guru 3,43 (sangat praktis) dan oleh siswa 3,76 (sangat praktis), sehingga media yang dikembangkan dapat dikatakan sangat praktis. Hasil penelitian tersebut menunjukkan bahwa media e-learning melalui aplikasi educate pada materi gerak parabola ini layak digunakan untuk meningkatkan pemahaman konsep peserta didik SMA/MA karena telah memenuhi kriteria validitas dan kepraktisan.

Abstract

The advancement of optical fiber technology has opened new opportunities in the development of high-accuracy sensors. This study focuses on the development of a Fiber Bragg Grating (FBG)-based sensor capable of simultaneously detecting temperature and pressure changes with high precision. FBGs are optical sensors that reflect specific wavelengths of light, which shift in response to external stimuli such as thermal expansion and mechanical strain. In this research, an FBG sensor system was designed, calibrated, and tested under controlled laboratory conditions to evaluate its sensitivity, linearity, and repeatability in detecting variations in temperature and pressure. The results show that the FBG sensor exhibits a high degree of accuracy and stability, with temperature sensitivity reaching up to 32 pm/°C and pressure sensitivity up to 32 pm/MPa. The dual-parameter sensing was achieved by using a configuration that separates the wavelength shifts induced by temperature and pressure through a compensation algorithm. This makes the proposed FBG sensor suitable for applications in harsh environments such as aerospace, biomedical, and industrial monitoring systems. The study concludes that FBG technology offers a promising platform for developing compact, reliable, and high-resolution sensing devices.
