Pengolahan Limbah Praktikum Mahasiswa Menggunan Alat Penyulingan Sebagai Bahan Praktikum Kelarutan Aspal Dengan Tetra Chloro Ethyline (TCE))

Abstract

Waste is material resulting from an activity or process that will no longer be used and can have a negative impact on society if it is not managed properly. The definition of waste can be found in RI Menperindag Decree No. 231/MPP/Kep/7/1997 and Government Regulation No. 18/1999, which states that waste is leftover goods or materials from production activities or processes whose function has changed. Waste has physical, chemical and biological characteristics. The types of waste can be grouped based on the source and type of compound, such as domestic, industrial, agricultural, mining, tourism and medical waste. The waste generated at the Civil Engineering Department Highway Lab, from practicum activities, student and lecturer research is in the form of liquid waste and solid waste. The liquid waste originates from the asphalt solubility test against Tetra Chloro Ethylene (TCE) and the extraction test waste is the solvent is Pertamax. This waste has the potential to be reused, namely by re-purifying it with a distillation process using specially designed tools. Based on the test results, it was found that the waste resulting from the practicum and research activities was still suitable for use or reuse by showing a solubility value that was not too dominant, namely only having a difference of 0.01%, namely the solubility of asphalt in the waste TCE of 99.63% while pure TCE has a solubility value of 99.64%. So it can be concluded that this waste can still be used for practical activities and further research without having to use a new TCE.
