Abstract

The degression of road performance was caused by several factors, particularly by road side activities. Tuanku Tambusai Road, the front side of Mall SKA is an economic region with large volume of traffic. This condition could be assumed in case the traffic volume gets higher, it will decrease the performance of road side, especially on busy hours due to the movement of vehicles to SKA Mall, the stopping public transportations, street vendors, and the parking motorcycles at road side. This research aims to evaluate the performance of Tuanku Tambusai Road, at the front of SKA Mall and find some solutions to overcome theproblems. The road performance analysis was based on Manual Kapasitas Jalan Indonesia (MKJI) 1997. The traffic data was collected from 3 days long, i.e. Saturday (3/2/2018), Sunday (4/2/2018) and Monday (5/2/2018). The results showed that busy hour was happened on Sunday at 12.45-13.45 WIB with Q = 2579,6 smp/hour, C = 3234 smp/hour dan DS = 0,80. Due to DS was higher than MKJI standard, which is DS < 0,75 some planning needs to be done in order to increase the performance of road. In order to reach the maximum standard, a specific lane was planned for vehicles which made their way into SKA Mall. The results showed that DS was able to meet MKJI standard, i.e. DS = 0,59.Keywords : Road Performance, MKJI 1997, Side Activities.

Abstract

Concrete is a brittle material and has low tensile strength comparing to other material. When the cracks occur, the quality of concrete will decrease, so the new innovations will be created to cover the weakness of concrete. The innovation is self healing concrete that uses bacteria as a medium that can close the cracks of concrete. This research used 25 ml bacillus subtilis with a concentration of 105 cells/ml as admixture to the concrete mix. The test conducted in this research was compressive and flexural tests carried out at the age of 28 dan 56 days. The test consists of two types of loading namely crushing crack test where the concrete cylinder was loaded until it failed and initial crack test when the concrete cylinder was loaded until first crack appeared. For the case of conducted crushing crack bacterial concrete were able to increase compressive strength of 14.71% and flexural strength of 6.96% compared to those of normal concrete at the age of 56 days. Furthermore, initial crack test conducted at bacterial concrete was able to withstand compressive and flexural loads of 17.15% and 3.17% higher than those of normal concrete. Keywords: concrete, crack, bacillus subtilis, compressive strength, flexural strength

Abstract

Concrete is a common material used in structures, such as foundations, roads, and bridges. Concrete has a high compressive strength, but the tensile strength of the concrete is low. At the time the tensile strength limit of concrete is reached, the crack will exist on the tension side of the concrete. The use of bacteria as an added ingredient in concrete is an innovation to reduce the crack. According to Pangeran and Karolina’s research (2017), the addition of bacteria to the concrete can also increase the compressive strength of the concrete. In this research, a 25 ml of Bacillus subtilis solution with the concentration of 105 CFU/ml were added to a concrete mixture. The concrete was soaked in normal water and sulfate solution with the concentration of 150 ppm and the physical properties were examined such as workability, porosity, and shrinkage. There were 3 variations in the specimens, namely normal concrete (BN), bacterial concrete (BB), and bacterial concrete soaked in sulfate solution (BBS). Theresults of this study indicated that slump on specimen BBS was 8.05% and 18.98% higher than specimen BN and BB, respectively. The porosity on specimen BBS was 11.07% and 14.47% higher than specimen BN and BB, respectively. Lastly, the shrinkage on specimen BBS was 1.42% and 18.54% higher than specimen BN and BB, respectively. So it can be concluded that bacteria does have a good effect on the physical properties and soaking the bacterial concrete on the sulfate can adversely affect the physical properties of concrete.Keywords : concrete, bacillus subtilis bacteria, sulfate, physical properties
