Abstract

Asphalt is an aggregate binding material in road pavement construction that plays a very important role in determining pavement performance although its composition is around 4-10% based on the total weight of the mixture. One effort that can be done to overcome these problems is to reduce dependence on oil asphalt by developing alternative binders. The addition of pome waste to asphalt becomes an alternative as a binding agent that can bind aggregates to asphalt pavement which is determined at the penetration value and asphalt softening point. In this study the penetration value and softening point without adding pome waste were 62.2 mm and 48.5 ° C then pome waste was added by 1%, 2%, 3%, 4% and 5%. From the addition of this pome waste to the penetration value has decreased while for the softening point with the addition of this pome waste has increased. For the penetration value of the index with the addition of pome waste, the penetration value of the index has increased from -0,686 for asphalt without the addition of pome waste increased to -0,245 at 5% addition, this indicates that the addition of pome waste makes the asphalt sensitive to temperature.

Abstract

Building construction requires soil conditions that have good bearing capacity so that they can bear the load on it. Clay soils with high plasticity are soils that contain lots of clay grains. The properties of clay that need to be considered are the properties of compression, permeability, and shear strength. To increase the carrying capacity of the clay by compacting it, so that the maximum density is obtained. Mixing the original soil with palm bunch ash and cement will increase the maximum dry density value of clay soil. The purpose of this study was to determine the compaction of the soil mixed with various percentages of palm bunch ash and cement, respectively 5%, 7.5%, and 10%. The addition of palm bunch ash and cement can reduce the value of soil moisture content and increase the value of the dry density of the soil so that the soil becomes denser. The largest dry density value in a mixture of 10% palm bunch ash and cement was 1.42 g/cm³, whereas the dry density value of the original soil was 1.32 g/cm³. The conclusion is that there is an increase in the dry density value of the soil and a decrease in the value of the soil moisture content with the addition of palm bunch ash and cement.

Abstract

The nature of the subgrade plays an important role in road construction. The subgrade can be compacted embankment. The physical and mechanical properties of embankment soil are values ​​or parameters to see the quality requirements. The purpose of this study was to determine the characteristics of the embankment soil as a subgrade. The method used is laboratory testing to obtain the physical and mechanical properties of the embankment soil. Soil samples were taken from Tenayan Raya, Kulim, Pekanbaru City. The results showed that the physical properties of the soil were classified as ML, PI 6.62%, and the mechanical properties of the soil with a CBR value of 17.8%. Conclusion The physical properties of the embankment soil should not contain organic matter and high plasticity. Mechanical properties of embankment soil for CBR value > 10% based on Bina Marga 2018 Revision 2 specifications for selected embankments.

Abstract

The Pekanbaru City North Cross Road is a national road connects the city of Pekanbaru with the northern border of Pekanbaru which is a causeway often damaged. So we need a system to predict the damage that occurs. This research method consists of data collection, data selection, the process using the backpropagation method, analysis, and evaluation. Based on the data obtained the most damage that occurs on this road segment is 60% cracking, 30% rutting damage, and 10% for potholes. Backpropagation are weight initiation, activation, calculating input weights, output bias, and changes in weight. In these stages, the output to be achieved is obtained with the smallest error approach.. The result is that the prediction of damage made there is an increase in the number of crack damage by about 3% with an MSE error value of 0.18535 with Matlab software

Abstract

Volume instability in expansive soils due to changes in moisture content results in damage to the supporting structure. Soil improvement is one of the efforts made for soil improvement. Soil stabilization is one part of soil improvement. Appropriate soil improvement needs to be carried out to see the performance of the soil to meet post-construction stability requirements. Chemical stabilization using cementitious soil materials can improve the engineering properties of expansive soils. The research objective is to analyze the value of engineering properties of expansive soil with cement. Experimental research method to determine the value of California Bearing Ratio (CBR and Atterberg limits. Expansive soil was stabilized with cement with variations of 10, 12, and 14% cement by weight. As a result, the value of engineering properties increased, namely the maximum CBR value of 7.40% in the 14% variation at a curing time of 7 days. The smallest PI value in the 14% cement variation is 13.65%, there is a decrease in PI value with the addition of cement. In conclusion, engineering properties of soil with cement stabilization increase the CBR value of soil and decrease the Plasticity Index value.

Abstract: A laboratory assistant is someone who has expertise and works in a laboratory and helps student learning processes (practicum) and lecturer research. In addition to laboratory laboratory assistants are also assisted by assisting the work of the laboratory. Given the importance of the role of a concrete laboratory assistant in supporting practical activities or testing in the laboratory, it is very important to improve the abilities and competencies of a concrete laboratory worker. These competencies need to be prepared considering technological advances, scientific developments continue to develop so that the roles and insights possessed by concrete laboratory workers are needed to answer all these challenges. In overcoming partner problems, the service team provides solutions in the form of concrete testing training for laboratory workers. The steps for implementing the solutions offered in overcoming these problems are four stages, namely (1) the planning stage, (2) the implementation stage, and (3) the evaluation stage. From the results obtained, there is an increase in the results of 62.1% of the preetest and posttest questions. Then 80% of the participants got a good score and 20% of the participants got a pretty good score.            Keywords: Laboratory Asistant, Concrete TestingAbstrak: Laboran adalah seseorang yang memiliki keahlian dan bekerja di laboratorium serta membantu proses pembelajaran mahasiswa (praktikum) dan penelitian dosen.
