Abstract

Plastic waste, which is one of the biggest environmental pollutants, can open up opportunities to be utilized in the field of highway construction because it is easy to obtain and has a more economical price as a porous asphalt mixture. Referring to this, a research was carried out on the characteristics of a mixture of porous asphalt with polyethylene terephthalate (PET) plastic waste as an additive to asphalt. The purpose of this study was to determine the effect of the use of PET plastic waste on the characteristics of porous asphalt mixtures. The method used is a laboratory scale experimental method based on 3 types of testing, namely marshall, cantabro loss and asphalt flow down. The gradation in this study used the open graded Australian Asphalt Pavement Association (AAPA) 2004. The test results showed that the addition of PET could improve the performance of porous asphalt mixtures. Stability, density, MQ, and VFA values increase with the addition of PET content so that they can prevent fractures due to traffic loads. The decrease in the cantabro loss value makes the mixture's resistance to disintegration better. addition of PET content up to 7.5% can reduce the flow value so that the mixture has optimal flexibility. However, the recommended PET content should be below 5% because in this study the penetration and ductility values did not meet the general specifications for 2018 Highways.

Abstract

The base course material uses mountain stone which is broken up with a stone crusher so that it has a high quality which makes it expensive. In this research we need an alternative material to replace fine aggregate that meets the specification requirements. One of the more affordable resources is sand aggregate. The purpose of this study was to determine the density and comparison of the California Bearing Ratio (CBR) value of the base course using sand as a substitute for fine aggregate. The method used in this research is laboratory scale testing to obtain data on aggregate characteristics, optimum moisture content, and CBR values. The base course aggregate mixture used was 55% coarse aggregate and 45% fine aggregate consisting of a mixture of fine crushed stone and 0%, 10%, and 20% sand substitution. The results showed that the KAO value decreased with the addition of sand aggregate. Laboratory CBR values increased with 0% sand substitution having a CBR value of 99.2%, 10% sand substitution having a CBR value of 90.6%, and 20% sand substitution having a CBR value of 84.1%. Only the laboratory CBR value with sand substitution of 20% does not meet the specifications for base A aggregate, namely a minimum value of 90%.

Abstract

Increased community mobility needs to be followed by the provision of transportation services that are tailored to the needs of travelers. To adjust to these needs, it is necessary to know the preferences of travelers in choosing the mode and level of service required by travelers. This research discusses the problem of choosing a mode of transportation between the royal-class Damri bus and the Lampung-Jakarta route plane. The purpose of this study is to determine the characteristics of travelers and the factors that influence mode selection, determine the probability of mode selection, and determine the condition of the Damri bus service level and the Lampung-Jakarta airplane route. The analysis carried out was multiple linear regression analysis with data from the results of distributing questionnaires to travellers, then a probability analysis was carried out using a binomial logit model. The results of the study show that there are factors that have an individual significant effect on the choice of mode, namely tariffs/costs, travel time, and level of security. The probability of choosing a mode for airplanes is 62% and for Damri buses is 38%. The service quality of the two modes has not been maximized, this can be seen from several passenger complaints, including Damri buses still using regular ship services, and the airplane fares that are imposed are expensive.Key words : characteristics, travelers, mode selection, probabilities. Peningkatan mobilitas masyarakat perlu diikuti dengan penyediaan layanan transportasi yang disesuaikan dengan kebutuhan pelaku perjalanan.
