A research on design and construction of purification equipment of water contaminated by heavy metals Fe, Cu, and Zn was carried out. The equipment was utilized to purify water sample of Siak River at a distance of 1m from the PT. RICRY of rubber industry in Pekanbaru. Analysis was performed by using Atomic Absorption Spectrophotometer (AAS). The analysis results showed that the concentration of Cu, Fe and Zn before filtration process sequentially were 0.3809 ppm, 0.0051 ppm, and -0.0012 ppm. After being filtered twice showed an absorption percentage for type I sieve (with carbon) on the heavy metals sequentially were Fe 75%, Zn 14.29% and Cu 10.78%. Sieve type II (without carbon) absorption percentage of each heavy metal were Fe 59.5%, Zn 7.75%, and Cu 0.0%, while the water discharge at the sieve type I (with carbon) obtained an average water discharge of 0.164 645 x 10-2 m3/s, and the sieve type II (without carbon) of 0.17838 x 10-2 m3/s. Based on the result the sieve type I with carbon has a better result for water purification treatment.

A research on the testing of concrete elasticity has been done in order to measure concrete compressive strength using a non destructive test based on sonic wave velocity. An equipment that was used for this research was a Sonic Wave Analyzer (SOWAN). In this research, concrete samples were formed in cylindrical shape with 15 cm diameter and 30 cm length. The compressive strengths of this concrete were 19 , 23 , and 25 ( ⁄ ). After that the time delay of sonic wave was measured. The research results showed that primary and secondary sonic wave velocity, elasticity, and compressive strenght were = 3525 m/s, = 1950 m/s, 23240 x N/ , and 24 x ( ⁄ ) respectively. Based on the data, it was concluded that this non destructive test based on sonic wave velocity can be used to measure the concrete compressive strength, because the values obtained were comparable to the values obtained using the Universal Testing Machine (UTM) which is a destructive test.

A research has been done in analyzing a coefficient absorption of composite material of oil palm trunk fiber and gypsum using a sonic wave analyzer (SOWAN) and carried out using sound wave of 150 Hz frequency. Sample was formed as a cylinder made from gypsum with 3:5 ratio of water and gypsum, formed a pipe with 7,5 cm outer diameter and heights of 2 cm, 3 cm, 4 cm, 5 cm, and 6 cm (sample thickness). The pipe with the outer diameter of 6 cm was used for making a cavity in the samples and then the composed of oil palm trunk fiber of ± 1 cm length with the variation percentage of fiber of 12,24%, 24,48%, 36,73%, and 48,97% filled in to each sample. Ao (initial amplitude) and A (final amplitude) then were measured by Sonic Wave Analyzer (SOWAN) with the intensity of 65 dB, 70 dB, 75 dB, dan 80 dB. Results of the measurements showed that the bigger percentation of fiber, the higher coefficient of sound absorption andthicker sample produced bigger the coefficient of sound absorption. The biggest absorption coefficient was 0,4957, due to the sample with 6 cm thickness when the intensity was 80 dB and the smallest absorption coefficient was 0,3088, of the sample with 2 cm thickness when the intensity was 65 dB. The maximum absorptioncoefficients of the sample thickness of 2 cm, 3 cm, 4 cm, and 5 cm were 0,3557, 0,3779,0,4155, and 0,4863, respectively. This showed that preparing the sample by method ofarranging the oil palm stem's fiber inside the sample was more effective to absorb the sound for low frequencies (150Hz) if viewed from the standard of absorption coefficientof gypsum was 0.29 for frequency of 150 Hz. Based on the results of this study the absorption coefficients exceed the minimum limit 0.15 as suggested ISO 11654 as a silencer.

A research has been done on the use of acoustic waves in order to separate pollutant particles in water. This research has been performed by an experimental method utilizing the second and the third harmonic mode of acoustic waves. The results showed that the use of both modes was affected by their intensity. It was proved that the treatment of the second harmonic mode wave yielded the difference of concentration of water that depended on the intensity level ( IL ) of the wave. The value of 0.035 mg/L, 0.09 mg/L, and 0.15 mg/L have been found respectively, for the IL of 83.2 dB, 92.4 dB, and 102.3 dB by second harmonic mode treatments to the water of 0.40 mg/L. Meanwhile, the use of the third harmonic mode wave treatments to the same water samples gave the differences of concentration of 0.07 mg/L, 0.11 mg/L, and 0.17 mg/L respectively, for the ILs of 65.9 dB, 75.2 dB, and 84.8 dB. It was showed that the treatment of the third harmonic resulted bigger difference concentration of the samples. The bigger the difference concentration, the better the separation of pollutant particle in the sample. It can be concluded that acoustic waves can be used to separate the pollutant particles in water.
