| Abstraksi | : | 'Eceng Gondok' was still considered as troubled weeds plant, since the growth was so fast and in 3-4 months able to cover more than 70% water surface. The research was done in Civil Engineering Laboratory University of Muhammadiyah Malang by prototype placement south area of University of Muhammadiyah Malang stadium. Compound material with 'Eceng Gondok' compound material: glue: cement was 1:1:2.5. Test was done in 3 sound sources 80 dB, 85 dB, and 90 dB. Test which was done to wall prototype was bounce back sound, escape sound, and sound absorption to eceng gondok wall by comparing to brick wall prototype with similar test. From test and calculation, there found average value for eceng gondok wall was not better in sound absorption with brick wall> eceng gondok wall in sound source 80 dB, 85 dB, and 90 dB found 31.63 > 28.96 dB, 36.64> 30.06 dB, 39.81> 29.95 dB. eceng gondok wall was better for escape sound with value brick wall < eceng gondok wall in sound source 80 dB, 85 dB, and 90 dB found 39.86 < 42.46 dB, 39.68 < 46.34 dB, 41.46 < 51.63 dB. And eceng gondok wall could be similar in echo sound with significance 5% at the sound source 80 dB, 85 dB, and 90 dB. |
