Abstract

Antioxidants play a role in preventing and repairing damage to human cells. Searches for antioxidant sources continue to be carried out including in P. subpeltatum plants. This study aims to compare the antioxidant activity of the bark, wood, and leaves of P. subpeltatum C.B. Rob plants. The materials were dried and then shaved to a fineness level of 80 mesh. Materials were extracted using the maceration method with ethanol solvent. The macerate was filtered and the filtrate obtained was concentrated with an evaporator. The three extracts were tested for antioxidants using the DPPH (1,1-diphenyl-2-picrylhydrazyl) Free radical scavengers method, ascorbic acid was used as a comparison. Absorbances was measured using UV-Vis spectroscopy. Each material was made in 5 concentrations. The IC50 value was calculated using the Blois regression equation. The results of the antioxidant test were obtained consecutively: stem wood with an IC50 value = 3.39 μg/mL, stem bark = 5.15 μg/mL, and leaf = 258.58 μg/mL, the IC50 value of ascorbic acid was 2.79 μg/mL. Based on these data, it shows that the antioxidant activity of stem wood and stem bark is in the high category, although still lower than ascorbic acid, while the leaf are included in the weak category.

Abstract

Noise pollution is a major concern in companies. The utilization of machines to support a production activity in factories or indutries can cause unwanted noise. PLTD Rema is one of diesel power plant companies in Gayo Lues regency which has been running for 18 years. Diesel engines at PLTD Rema will certainly cause noise that disrupt the workers’ hearing. The aims of this study are to identify the noise level, map noise, and examine workers' insights of noise in the area of PLTD Rema. This study shows that the highest noise level of 91.3 dBA lies at sampling point 1. Meanwhile, the lowest value of noise level of 68 dBA lies at sampling point 12. If all of the results of the noise level evaluation at 12 sampling points are evaluated with the Regulation of the Minister of Manpower and Transmigration No. 13 of 2011, the noise levels acquired are unthreatening for all PLTD Rema’s empolyees, except for the area of diesel engines. Moreover, the mapping of noise levels using urfer 13 software consists of 5 different colours (green, blue, red, yellow, and orange). The last one, the workers' perception towards noise has been accepted or H0. Therefore, the noise produced at PLTD Rema has no impact to thier workers’ performance.
