Abstract

Dual Translasional dynamic vibration absorber (dDVA) dua buah masa DVA yang dapat bergerak pada arah translasional dan diberikan pada sistem guna meredam getaran translasi- rotasi sistem. Penelitian terkait penggunaan dual translasional DVA untuk mengurangi getaran dengan metode simulasi telah dilakukan, namun belum ada kajian terkait penggunaannya metode eksperimental dalam penelitian tersebut guna melakukan hasil validari dari hasil simulasi yang dilakukan. Dalam penelitian ini dilakukan kajian terkait karakteristik response getaran sistem 2 DOF setelah penambahan dual translasional DVA dengan pendekatan eksperimental dan membandingkan hasilnya dengan data hasil simulasi. Perbandingan antara data hasil eksperiment dan simulasi dilakukan guna mengetahui tingkat error yang terjaidi antara kedua metode tersebut. Data hasil simulasi diperoleh dengan mensimulasikan kembali persamaan gerak yang ada dari studi literatur, seangkan data hasil eksperiment diperoleh melalui pengujian melalui alat uji DVA dengan dilakukan beberapa perubahan fekuensi eksitasi. Dari hasil penelitian ditunjukan karakteristik getaran hasil eksperiment adalah sama dengan karakteristi  getaran hasil simulasi, dengan  rata-rata tingkat segnifikansi sebesar 91,5%. Adanya error yang terjadi antara hasil simulasi dan eksperiment lebih dikarenakan oleh tersalurnya sebagian getaran dari sistem utama kepada lingkungan di sekitar sestem, sehingga mengakibatkan adanya perbedaan hasil anara simulasi dan eksperiment.

Abstract

Technology's impact on education and the industrial sector is growing, and in this day and age, it is constantly used in a variety of ways to help people carry out their daily tasks and more. One of these is computer-aided design (CAD) technology. Other technologies that have emerged lately and are helping people with their problems include 3D printing technology. Both of these technologies are widely used as tools that utilize design and real-world projects. SMK education must be characterized by a few technologies that will become the foundation of the working world for students; therefore, instruction and learning must be provided as a means of preparing students for the digital age. Our collaborative efforts with SMK Wahid Hasyim Glagah aim to provide education and training related to the use of design and 3D printing technologies. We use public speaking as one of our teaching methods, along with intense visual and practical training conducted at the Universitas Qomaruddin Gresik Laboratory. The expected outcome of this activity is that the students will be able to use the computer-based design application to create drawings and be able to innovate in various design-related fields independently. They will also be able to use a 3D printer as a source of accurate 3D drawings so they can innovate in the field of business.
