Abstract

The difference in polarity between materials often prevents direct interaction; therefore, a compatibilizer is required to facilitate reactions between polar and non-polar substances. This study aims to investigate the effect of maleic anhydride (MA) concentration on the grafting process of MA onto polypropylene (PP) chains, using benzoyl peroxide (BPO) as an initiator. The blending method employing an internal mixer was used to combine the materials, and the degree of grafting was determined via titration, with three replicates performed for accuracy. The results indicated that the highest grafting degree, 10.28%, was achieved at a composition of 86% PP, 11% MA, and 3% BPO. Fourier Transform Infrared (FTIR) spectroscopy analysis of polypropylene grafted with maleic anhydride (PP-g-MA) revealed new absorption peaks at wavenumbers 1707 cm and 1162 cm. Furthermore, increasing the concentration of maleic anhydride did not significantly affect the grafting degree. This study provides valuable insight for the development of PPg-MA compatibilizers.

Abstract

The purpose of this study is to assess water quality, specifically pH, conductivity, total dissolved solids (TDS), salinity, and turbidity. The research utilizes quantitative methods and covers 15 sampling points across the Timbalun River basin in Padang City, West Sumatra, Indonesia. Samples were measured based on several parameters, with three repetitions for accuracy. The testing took place from August to September 2024. The results showed that some water quality parameters, such as pH and total dissolved solids, met the standards outlined by Ministry of Health Regulation No. 2 of 2023. However, other parameters, including salinity, conductivity, and turbidity, did not meet the specified thresholds. It is essential to implement treatment measures to ensure the water meets the required standards for its intended use.
