Abstract

This study aims to develop ISLE-based STEM learning media and utilize standing wave resonance tube teaching aids to study the phenomenon of stationary (standing) waves. The method used is research and development (R&D) with the ADDIE development model (Analysis, Design, Develop, Implement, and Evaluate). The results obtained from this study are learning media in the form of Practical Teaching Aids (APP), wave simulation programs and student worksheets for traveling wave and stationary wave experiments. The two learning media have gone through the validation process of material experts and media experts and have been declared suitable for use/implementation by students. The developed APP makes it easy for students to visualize stationary waves in a tube. Student worksheets which is prepared using the ISLE-based STEM model approach, is used as a guide in achieving learning objectives by building students' thinking concepts about stationary wave material through resonance tube experiments. The use of APP provides a visualization display of experimental results so that it helps students understand the concept behind physics processes that are invisible like standing waves

Abstract

Analisis lapisan tanah yang dilakukan di lapangan salah satunya, metode Cone Penetration Test (CPT) yang menghasilkan parameter utama nilai tahanan ujung konus (qc). Sedangkan, metode Multichannel Analysis of Surface Wave (MASW) adalah metode dari bidang ilmu geofisika untuk menganalisis lapisan tanah yang dapat menghasilkan parameter kecepatan gelombang geser (Vs). Penelitian ini bertujuan untuk mendapatkan parameter gelombang geser (Vs) MASW dan parameter tahanan ujung CPT untuk menganalisis lapisan tanah serta membandingkan hasil dari kedua metode tersebut terhadap karakteristik lapisan tanah sebagai perencanaan pondasi bangunan sipil. Akuisisi data dilakukan di TPI (Tempat Pendaratan Ikan) Lampulo, Kecamatan Kuta Alam. Hasil penelitian pada pengukuran MASW didapatkan nilai Vs sebesar 70 - 130 m/s. Berdasarkan SNI 1726-2012, tanah pada lokasi penelitian termasuk ke dalam  kategori Tanah Lunak (SE). Data CPT yang telah dikorelasikan meggunakan persamaan empiris menjadi nilai Vs menunjukkan hasil yang  relatif sama dengan klasifikasi tanah pada MASW. Jenis pondasi yang sesuai diterapkan pada lokasi penelitian adalah pondasi tiang karena letak tanah keras berada pada kedalaman lebih dari 10 meter dibawah permukaan tanah.
