Hazardous Waste Generation and Composition from Electric Train Activities

Abstract

Transportation is one of the human needs in a big city like Jakarta. Currently, the implementation of public transportation is being scaled up to reduce vehicle emissions, especially those fueled by oil. One public transportation activity is electric trains that produce hazardous solid waste. This study aims to identify the generation and composition of hazardous waste from electric train transportation activities in Jakarta. This study uses quarterly secondary data from July 2019 to March 2020. The composition of hazardous waste is calculated based on the w/w weight ratio, then looks at the effect of time and phase of each time hazardous waste generation from electric train activities. The composition of the largest hazardous waste is contaminated packaging, scrap-contaminated, and contaminated waste is 28.14%; 23.34%; and 10.72%, respectively. The lowest hazardous waste generated is used lamps at 0.10%. Hazardous waste arises from activities that contaminate to produce hazardous or toxic properties. Based on the phase, solid hazardous waste is 96%, and liquid is 4%. The analysis of the variance test showed no significant difference in terms of time (sig. 0.679) and phase (sig. 0.534). Therefore, the data used show no difference in hazardous waste generated by time or phase.

Evaluation and Management of B3 Waste Sludge via the Sludge Oil Recovery (SOR) Program at PT. X Plaju

“…Based on PP 101 of 2014 concerning management of hazardous and toxic waste, hazardous and toxic materials from now on abbreviated as B3 are substances, energy, or other components due to their nature, concentration, or amount, either directly or indirectly pollute the environment. Meanwhile, waste is a business or activity [8,9]. So that, hazardous and toxic material waste is the residue or a business or activity that contains B3.…”

“…The density of sludge oil based on the above data is 0.85 gr/cc. At the same time, the pH of sludge oil has a value of 7.9 which means that sludge oil has a neutral pH (6)(7)(8)(9) [17].…”
