Abstract

Bus Rapid Transit (BRT) is one of the types of bus-based public transportation that provides fast, convenient, and affordable urban transportation. The BRT service in Central Java is called Trans Jateng and is managed by the Transportation Agency of Central Java Province. The operational concept of Trans Jateng is to serve routes that connect urban agglomeration areas in the province of Central Java. Trans Jateng plans to develop future services grouped into service corridors based on the existing development areas in Central Java, including the Kedungsepur, Wanarakuti, Banglor, Bregasmalang, Petanglong, Subosukowonosraten, Barlingmascakeb, and Purwomanggung agglomerations. In addition to opening new corridors, the development of Trans Jateng BRT services can also be carried out by expanding existing services; therefore, a comprehensive study is essential to monitor and track the progress of the research. This paper will map the literature on service expansion, BRT, and Trans Jateng. The literature database was taken from Google Scholar and analyzed using the VOSviewer tool with a mapping of previous research. The results of this research are highly useful for understanding the current development of research on the expansion of Trans Jateng BRT services in the future.

Abstract

Expansive clay which is a problematic soil is spread almost all over the world, including Indonesia. In various regions in Indonesia, expansive clay has damaged the infrastructure above, causing high maintenance costs. Expansive clay often becomes a problem when infrastructure is built on it, due to its large swell and shrink properties. Improved stabilization of expansive clay is required to improve mechanical behavior (shear strength, compressive strength and modulus of elasticity). In this study, the effect of increasing shear strength, unconfined compressive strength and modulus of elasticity of expansive clay added with SiO2 nano material will be investigated. SiO2 nanomaterial can be produced from processing waste from geothermal power plants. The percentage of SiO2 nanomaterial mixture used in this research is 0%; 1%; 2% and 3% compared to dry soil weight. The increase in shear strength, unconfined compressive strength and modulus of elasticity will affect the mechanical behavior of expansive soil. This increase in mechanical behavior also means increasing the bearing capacity of the soil and this is very influential in stabilizing expansive clay. From laboratory substantiation that have been carried out, the laboratory test results show an increase in modulus of elasticity of 17%. An increase in shear strength of 64% and an increase in UCS stress of 91%, which occurs at the optimum mixing nano SiO2 ratio.
