Abstract

Penelitian ini bertujuan untuk menghasilkan modul pembelajaran berbasis guided inquiry pada materi alat-alat optik dan menguji efektivitasnya. Penelitian dan pengembangan (Reseach and Development) ini mengacu pada model Borg and Gall (1983) yang dimodifikasi. Teknik pengumpulan data yang digunakan adalah observasi, angket, tes dan dokumentasi. Hasil uji kelayakan menunjukkan bahwa modul pembelajaran fisika berbasis guided inquiry pada materi alat-alat optik layak digunakan dengan persentase skor kelayakan dari ahli materi sebesar 87,27% dan dari ahli media sebesar 91,67%. Hasil uji efektifitas menunjukkan bahwa modul yang dihasilkan efektif digunakan. Hal ini ditunjukkan dengan hasil perhitungan uji t terhadap data tes hasil belajar peserta didik. Hasil uji t diperoleh ttabel sebesar 2,048 dan thitung sebesar 6,433, sehingga thitung>ttabel yang artinya ?0 ditolak dan ?? diterima.

Abstract

The inclination of a building can be a serious issue with potentially fatal consequences if not addressed correctly from the beginning, as it may lead to the building collapsing. Therefore, a tool is needed to detect the tilt of a building to determine the level of inclination. This research aims to design and build the Tilt Building Gun (TB Gun) as a portable device for detecting building inclination that can be easily used anywhere. The research methodology includes the design of hardware, development of software, and overall testing of the device. A miniature building in the form of a laptop-sized box was also constructed. The components used in this research include Arduino Nano, 2 HC-SR04 ultrasonic sensors, and an OLED display. The test results of ultrasonic sensor 1 for horizontal direction yielded an accuracy value of 99.06% and a relative error of 0.94%. Meanwhile, the testing results of ultrasonic sensor 2, with an additional distance of 13.1 cm (distance between ultrasonic sensor 1 and ultrasonic sensor 2 to the ground surface) for vertical direction, resulted in an accuracy of 96.29% and a relative error of 3.71%. Subsequently, testing the building inclination angle with a horizontal distance of 25 cm for ultrasonic sensor 1 and a vertical distance of 20 cm for ultrasonic sensor 2 yielded an accuracy of 98.86% and a relative error of 1.14%. From these accuracy values, it can be concluded that the prototype has excellent accuracy. The building inclination angle data is then displayed on the OLED.
