Abstract

One issue that might lead to environmental disturbances in Indonesia's varied areas is solid waste. It is possible to execute waste management effectively, and one such implementation is the installation of waste transportation. If waste transportation fleet is unable to handle the current waste generation, which may result in waste accumulation, then the problem of transporting waste may arise. In order to address this issue, assistance is required in the form of waste transportation costs. In accordance with the local conditions at the time of the study, this paper analyzes the calculation of waste transportation fees. The collection of information was done to determine how waste transportation was currently operating, including the number of vehicles, the distance that went, their rotation, and their carrying capacity. According to the study's findings, the cost of garbage transportation is Rp. 3,277/km or Rp. 21,257/m3 for armroll trucks and Rp. 5,980/km or Rp. 86,459/m3 for dump trucks. These findings show that the fee for Armroll trucks is higher than the levy for dump trucks. This is because Armroll vehicles have a longer service route and use more fuel.

Abstract

The increase in development growth throughout the world every year is directly proportional to the increase in demand for construction materials. To overcome the very limited sources of natural materials, alternative materials are needed as substitutes for construction materials. Utilizing nickel slag waste as an alternative material to replace natural aggregate to reduce the extraction of excess natural aggregate and preserve limited natural resources. The purpose of this study was to determine the Marshall characteristics and ideal composition for using nickel slag as a substitute for aggregate in worn-coated asphalt concrete (AC-WC) mixtures. The test specimens used were a mixture of worn coated asphalt concrete (AC-WC) with variations in nickel slag content, namely 0%, 10%, 40% and 70% and optimum asphalt content (KAO) respectively of 5.5%; 6%; 5.5%; and 5%. Based on the results of study that has been carried out, the optimum stability value was obtained at 1087.38 kg at a nickel slag content of 70% with an optimum asphalt content (KAO) of 5%. This value is greater than the stability value obtained at a nickel slag content of 0% with an asphalt content. optimum 5.5%, namely 1034.39 kg. From these results it can be concluded that nickel slag can improve the performance of worn coated asphalt concrete (AC-WC) mixtures and the ideal composition of nickel slag is at a nickel slag content of 70% with an optimum asphalt content (KAO) of 5%.
