Abstract

Concrete has some advantages and some deficiencies. The advantage of concrete is the character that concrete can resist from compressive strength and the deficiency of concrete is the character that concrete can’t resist from tensile strength. One of the solution to increase the resistance of concrete from tensile strength is mix the concrete with fiber. The fiber will be used are natural fiber and fabrication fiber. The natural fiber is Agave Cantula Roxb and the fabrication fiber is fiber glass. The fiber that will be mixed to Polymer Modified Mortar is a short fiber that spread randomly. the adding of short fiber has two aspects the first is fiber length and the second is volume fraction. The fiber length is 1,0 cm, 1,5 cm, 2,0 cm, 2,5 cm, 3,0 cm and the volume fraction is 1%, 2%, 3% from the volume of cylinder test object. The test object will be test on 3 days and 28 days for tensile strength test, for compressive strength test the test object will be test on 3 days, 7 days and 28 days. Result of testing is natural fiber have highest tensile strength on fiber length 2,0 cm and the volume fraction is 3% while the fabrication fiber has highest tensile strength on fiber length 2,0 cm and the volume fraction is 2%. The compressive strength and the tensile strength of Polymer Modified Mortar with Agave Cantula Roxb Fiber is not far different from the compressive strength and the tensile strength of Polymer Modified Mortar with Fiber Glass.

Abstract

Soft soil has low bearing capacity and high compressibility that can cause instability and long-term degradation that can make around some road settlement or wavy. A solution to prevent this soft soil problem was built Modified Chicken Foot, The function of Chicken Foot Foundation is to increase its bearing capacity. This research is using single load with variation distance of triangle foot foundation pattern whereas analysis of deflection using finite element method based. The research shows displacement result is depend on distance between load position and foot foundation, the closer distance between foot foundation the less it would result. The displacement result that happened at roadside is larger than at middle of the road, the difference between them is -6,8% up to 67% and The displacement result that happened in plate without pipe is larger than a plate with pipe, the difference between them is 12,31% up to 59,41%.

Abstract

Cakar Ayam Modification System (CAM) has been widely used as one of the solutions to road pavement problems in soft subgrade, although construction costs were initially high, the total costs incurred were smaller due to small maintenance costs. This research analyzes the deflection produced in a triangle patterned CAM system and quadrilateral with variations in the distance between claws of 2.25 m. Loading uses truck loads based on SNI 1725 2016 with three different position variations each in the middle and edge of the pavement. The analysis was carried out using Finite Element Method-based software which has been proven to be able to approach the original conditions in the field. The results of the analysis show that the CAM pattern with triangular pattern is better at reducing deflection that occurs compared to quadrilateral CAM systems. The deflection difference produced by the triangular CAM system against the clawless pavement system reached 36.97% while on the quadrilateral CAM system the difference was only 28.56%.

Abstract

Electricity is a basic requirement in carrying out activities. However, over time, the electricity needs to increase but the availability of electricity is still stagnant. So that the necessary innovation of electricity generation. Solar power plants (PLTS) can be a solution to this problem. PLTS tends to require extensive land, therefore the idea of utilizing the reservoir as a PLTS location. In this penelitin selected Reservoir Bening / Widas as PLTS location. The calculation of the extent of the permit puddle needs to be done to find out how much PLTS design can be built. Furthermore, it is necessary to calculate the energy generated as well as economic feasibility analysis. The results of this study indicate that the area of permit inundation in the Bening / Widas Reservoir is 944893 m2 and PLTS which can be built as many as 20 modules with a design area of 1 module PLTS is 8000 m². The energy produced by 20 PLTS modules within 1 year is 19668.52 MWh.

Abstract

No fines concrete can be known such as porous concrete, no-fines concrete and pervious concrete, because not use of sand in the mixture causing the cavities between coarse aggregates. When the rainy season, especially in urban areas there are many flood because the water is difficult to infiltration into the ground. Because permeable nature of non-fines concrete which can accelerate the absorption of water to the soil and to the water channel, reduce run-off and increase groundwater reserves. In this research will study for compressive strength and infiltration in non-finnes concrete. This research uses coarse aggregates from the results of stone crushing machines with coarse aggregate sizes (5-10) mm. cement: aggregate ratio used 1: 2; 1: 3; 1: 4; 1: 5; 1: 6; 1: 7; 1: 8. The study began with material checking, planning of material requirements, making non-sand concrete, then testing compressive strength, and infiltration testing at the age of 28 days. The results showed that the compressive strength of non-finnes concrete with a variation of the ratio of cement : gravel 1: 2  is  33.19 MPa while for a mixture of 1: 8 it is 5.23 MPa. The Infiltration rate has increased along with the greater variation in the ratio of the mixture. The maximum infiltration rate for a mixture of 1: 8 is 9.44 mm/sec. The infiltration rates in no-finnes concrete can be used to accelerate the absorption of water into the soil and can function to reduce water on the surface of the yard.
