Abstract

The work built on the land which high plasticity clay (CH) that has a relatively low carrying capacity will have a short service life. To overcome this problem, efforts are made to improve the geotechnical properties of the soil by stabilizing using bottom ash (coal waste) and cement. The addition of this mixture aims to determine its effect in efforts to improve the physical and mechanical properties of high plasticity (CH) clay. The sample making in this research is based on the variation of bottom ash mixture 5%, 10%, 15% and the variation of the cement mixture is 3% and 5% of the dry weight of the soil. The UCS test was carried out as a reference to see the effect of using a mixture of bottom ash and cement. Testing of UCS samples was carried out based on curing time, with the following curing variations, without curing, 7 days and 28 days. Based on the results of the original soil UCS test, the Cu value is 10.55 kPa and the best mixed soil test value is in the variation of the soil mixture L-S5-BA15-C28 with a Cu value of 30.71 kPa. The conclusion from the research proved that the addition of a mixture of bottom ash and cement was able to increase the Cu value by 291.09% at 15% bottom ash content and 5% cement with a curing time of 28 days.

Abstract

Along with the growth of society and technological improvements, the demand for electricity continues to increase. However, the development of the electric power system is not sufficient to supply the needed electrical energy. For this reason, it is necessary to regulate and manage a good electricity distribution system so that the current growth of community needs is met and has a high enough reliability. The installation failure in the electric power system cannot be avoided due to the long transmission distance. This has a major effect on the flow of power in electric power transmission resulting in a decrease in voltage and loss of electrical power. One of the ways to overcome voltage stability and improve the reliability of the electrical power system is to use a Flexible Alternating Current Transmission System (FACTS). One of the FACTS devices is the Thyristor Controlled Series Compensator (TCSC). The TCSC is installed in series with the transmission line and is used to increase the power capabilities of the transmission line. Regulating the reactance of the transmission line can be done by controlling the reactance of the TCSC so that the power flowing can be increased. After conducting a power flow study using the MATLAB 2016a PSAT toolbox software, it was found that the voltage on the Bangkinang bus was 0.9868 p.u (148.02 kV) and on the Garuda Sakti bus was 0.9637 p.u (144.55 kV). After installing the TCSC on the Riau 150 kV transmission system, the TCSC was installed on the Garuda Sakti transmission line - Balai Pungut. The installed TCSC rating is 24 Mvar. The value of the alpha parameter is 0.2 and (-0.8) radians. After installing the TCSC, voltage stability the Bangkinang bus and the Garuda Sakti bus increased to 0.99008 p.u (148.512kV) and 0.97693 p.u (146.535kV). The percentage increase is 0.4% on the Bangkinang bus, 1.15% on the Garuda Sakti bus, the average stress on the object of research has increased by 1.15%.

Abstract

Based on the Work Plan and Budget Plan of Public Works Office, the Riau Province service in 2019, the provincial road handling program in Pekanbaru City, Riau Province is only based on the level of damage to road conditions and the level of road stability. The Ministry of Public Work has a definition of the purpose of road handling which is 100% stable roads. The level of road stability is determined by two criteria, the first one is steady in construction and the second is steady in traffic services. The purpose of this study is to obtain a priority sequence for handling provincial roads in the Tampan District of Pekanbaru appropriately by involving relevant parties. This study used the AHP method with 5 (five) criteria that were used to determine the priority of road handling, that is road conditions, traffic volume, accessibility, mobility and regional development. Based on AHP analysis, the importance level of each criterion is obtained to determine the priority of road handling. The results showed that the criteria for road conditions gains the highest weight 39.57% then level of accessibility 18.33%, then the criteria for regional development 18.25%, the criteria of traffic volume 12.51% and mobility criteria 11.35%. This study concludes that the most prioritized road sections in handling provincial roads in the Tampan District of Pekanbaru City in planning for 2020 is S.M Amin Road and Tuanku Tambusai Road and this study proves that the results of the author's analysis are different from the provincial roads planned by the government which to be handled in 2020, S.M Amin Road and Soekarno-Hatta Road.

Abstract

Adsorption is a process in which solute liquids accumulate on the adsorbent surface and form a thin layer of atoms or molecules. The adsorbent used was shrimp shell powder. Utilization of the adsorptionprocess in the absorption of Cu metal is useful for determining the isotherm model and adsorption kinetics. In this study the adsorption process was carried out by varying the concentration of adsorbate(10, 20 and 30 ppm) and the pH of the Cu metal solution (5, 7 and 9) at room temperature. The largest adsorption capacity occurred at the adsorption pH of 5 and the initial solution concentration of 10 ppmwith an adsorption capacity value of 88.28%. The isotherm model of the Cu metal adsorption process follows the Harkins Jura isotherm equation with R2 value of 0.9990. The kinetics of the Cu adsorptionprocess followed the Elovich kinetics model with a value of R2 0.9914 and a constant adsorption rate of 0.631 at an adsorbate concentration of 10 ppm and a pH of 7 Cu metal solution.Keywords : Adsorbent, Adsorption, Isotherm, Kinetics, pH
