Abstract

Kebisingan menjadi suatu masalah yang tengah dihadapai oleh masyarakat terutama masyarakat yang tinggal didaerah perkotaan yang sangat ramai oleh berbagai macam aktivitas. Bahan pernyerap suara atau bahan akustik adalah bahan khusus yang dibuat untuk fungsi menyerap bunyi pada frekuensi tertentu. Material yang bersifat lembut, berpori dan berserat diyakini mampu menyerap energi suara yang mengenainya. Pelepah pisang dan eceng gondok adalah salah satu contoh material alami dengan karakteristik berpori. Percobaan ini menggunakan metode tabung impedansi, dengan pengukuran intensitas bunyi yang divariasikan dari level 1 hingga level 5 pada frekuensi 200 Hz, 400 Hz, 600 Hz, dan 800 Hz. Berdasarkan hasil nilai koefisien absorbsi, pelepah pisang memiliki koefisien absorbsi tertinggi pada frekuensi 800 Hz, sedangkan eceng gondok memilki koefisien absorbsi tertinggi pada frekuensi 600 Hz. Sehingga pelepah pisang lebih efektif daripada eceng gondok, sebagai bahan akustik alami.

Abstract

Piezoelectric constituents consist of PbZrTiO3 or PZT which contains lead (Pb) hich is industrial waste which is hazardous if it enters the human body. Based on this, the researchers used environmentally friendly kitchen materials in the form of Potassium Bitartrate and Sodium Bicarbonate as a substitute for the original piezoelectric material. Through the experimental method of mixing the two materials, the evaporation and refrigeration methods, amorphous solid forms were obtained. The solid is then coated with aluminum and tested for suitability by measuring the stress of the material before and after being vibrated. The voltage obtained after being vibrated formed an exponential graph with the highest voltage of 0.28 V. Then, the material was tested again for its feasibility in charging the capacitor and the voltage generated by the capacitor was obtained at. 0.0221V. Basic knowledge related to cross-curricular and subject-specific sustainability.
