Authors: Darmawan Altheo , Leman Sunarjo
Published: December 2020

In the world of construction the use of mild steel is increasing due to the relatively light material and has great strength. This makes the producers start to innovate with the addition of reinforcement to get greater strength. Mild steel is formed from the grinding process on steel plate sheets. Because its thin thickness makes mild steel susceptible to buckling. The use of mild steel as a structural component requires great strength with the addition reinforcement. This research will discuss the effect of embossment width and dimensions on the compressive strength values of mild steel by the finite element method. This thesis uses MIDAS FEA finite element method program. The channel profile used is 75 mm x 34 mm x 5 mm x 0,65 mm with length 2000 mm. Model used is with and without stiffener and embossment distance variation from 15 - 150 mm. Boundary condition used hinge-roller, loading use axial load. The results of the analysis found that the greater the embossment distance, the greater the compressive strength produced. failure that occurs in a stiffener model that has embossment is lateral buckling

Authors: Christabel Pardamean Joshua , Noor Tajudin Anissa
Published: December 2020

Roads have the strength and durability to be able to handle the existing traffic load for their planned lifespans, and damage must be minimized. Methods of minimizing damage include self-healing. Before testing self-healing ability, steel fibers that have a solid density and as a good conductor must be tested for their mechanical characteristics in the AC-WC mixture. These consist of the Marshall characteristic tests and the volumetric characteristic test. With an asphalt content of 5.7%, the 0.25%, 0.5%, 0.75%, and 1% addition of steel fibers into the asphalt- concrete wearing-course (AC-WC) mixture increases the value of Void Filled with Asphalt (VFA), stability, and the Marshall Quotient and reduces the value of Void in The Compacted Mixture (VITM), Void in Mineral Aggregate (VMA), and flow. However the VITM value obtained is below the 3% requirement, because the number of cavities in the mixture is already close to the minimum requirement without the addition of steel fibers. Another reason is the high 5.7% asphalt content. The optimum steel fiber content, obtained using the narrow range method, is 0.625%. Based on its mechanical characteristics, steel fiber is a recommended additive.

Published: December 2020

The conventional pushover method has 2 major drawbacks, it cannot account for the higher mode effect and do not consider the change in lateral load pattern when the structure reaches its inelastic phase. To overcome those limitations, in this research will present the Adaptive Force-Based Multimode Pushover Analysis (AFMP) method, in this method the higher mode effect, and the change in lateral load pattern have already been considered. This research will compare the result of evaluation using triangular and uniform load pattern with the AFMP load pattern using 1, 2, and 3 modal pairs towards its effects on non linier seismic behaviour of a building with the first mode being not dominant. The analysis resulted that using the AFMP method yields to a higher seismic response on the upper floors, caused by the higher being considered in the analysis. The triangular load pattern, resulted in smaller seismic response on all stories than the AFMP method, while the uniform load pattern tends to overestimate the response on the lower floors. Based on the performance criteria of FEMA 356, the conventional pushover resulted in Life safety performance level, while the AFMP also resulted in Life safety performance level.

Authors: Chery M F , Susilo A J
Published: December 2020

Shallow foundation and slab on ground that were built on soft clays might have some settlement because of the low bearing capacity. If the settlement that happened was a differential settlement, it can cause damage to the structure. There are many ways to fix the soil by improving the bearing capacity such as using wood pile. Wood pile is often used because it was easy to find, easy to use, and cheaper than using the pile made of concrete. There are many types of wood that can be used, for example dolken wood, mangrove, and bamboo. Those type of woods have different specification that effected the wood strength as a pile to improve the soil bearing capacity. The diameter and length of the wood also influence the pile effectiveness. All this factor can give a different result in reducing the settlement that happened on the soil.

KMHE is one of the efforts of Indonesia’s government in advancing the technology of electric vehicles and fuel vehicles in terms of more efficient use of energy. The prototype of the SEM electric car is an electric car made by UNTAR Engineering students that will be included in the upcoming KMHE. The prototype of the SEM electric car uses a BLDC motor as a drive. The BLDC motor is controlled by an electronic controller. Therefore, the BLDC motor controller simulation was designed which can be used as a reference in designing BLDC motor controllers that will be used in KMHE 2020. From the simulation results, the maximum speed of the BLDC motor is obtained by using a controller designed at 2680 rpm. The speed of an electric car of 40 km/h can be achieved by adding a proper transmission system from an electric motor to the car wheel.

Retaining wall is a very important structure in the basement construction process. The planning of the retaining wall, whether in the design or in the processing step should be precise, otherwise, it can be disastrous. In the construction process, problems sometimes happen when the excavation process is going on. Therefore, the role of retaining wall is crucial. If the retaining wall doesn’t function well, the soil around the excavation site will shift and move and it can cause a rift or even more fatal failures to the structure. The analysis on this study is the failure analysis on retaining wall type secant pile. This analysis will be focusing on the failure that happen on primary pile. The analysis is done by reducing the strength of the primary pile based on the potential failure that might happen. This aims to test the deformation on the secant pile system, if there’s a failure on the primary pile. It will be done in two different types of soil, clay and sand.

The parking of car in the smaller space area is very difficult for the driver and it consumes more time. While in the parking, the drivers used to wait for proper place so that engine idle time also becomes more. In this paper we are creating a prototype of the collateral parking so to reduce the parking time, engine running time, reduce the pollution, and reduce occupying the space. The angle of steering systems always having the angle to tilt, but the extreme level of angle at 90° cannot be achieved in normal steering system. To minimize this issue, we have perpendicular rotation of wheels with steering control we can achieve the parking system easier. This collateral parking system makes our vehicle to park in less space area also.

There is various energy resources scattered around the world. As the population increases the energy demand is posing challenges to supply of fuels. The emissions from various industries and transports cause the main reason for Greenhouse gas, i.e. carbon emissions. Hence there it is right time to find an alternative fuels such as biofuels from plants and vegetables which is an efficient way to reduce these emissions. Biofuel are produced from crops like wheat, soybean and sugarcane, jackfruit, algae. Although there are various methods in production of biofuel, the most common is transesterification method. In the transesterification process the viscosity of the bio oil is reduced to make it suitable for engine. In this study we deal with analysis of the Emission characteristics of Jackfruit peel oil with three hole nozzle. The following emission characteristic of Hydrocarbon (HC), Nitrogen oxide(NO), Carbon dioxide(CO2), Particulate matters, Carbon monoxide(CO) are investigated in this paper.

To meet the regular global emission norms, the transition of fuel development stages was incorporated in petrol/gasoline engines from Carburetor type to Throttle fuel injection/Single point petrol injection and throttle injection to Port/Manifold fuel injection. To achieve advanced emission norms, conventional or manifold fuel injection (MPFI) engines are replaced by Gasoline Direct Injection (GDI) engines. To attain efficient range of fuel economy, power output and controlled concentration of emissions coming out of an engine exhaust, the control of ignition timing and fuel injection timing are much important. In this work, the electronic hardware part includes controller/Arduino with ignition control and fuel injection drivers were used for controlling both ignition timing and fuel injection timings. In order to control these timings, the position of piston with respect TDC was measured with the help of crank and cam position sensors. Software required for ignition and fuel injection timings with crank and cam position are developed for controlling an engine with arduino and drivers.

By witnessing the evolution of material science in the engineering fields, many engineering products are manufactured by fiber reinforced composites instead of metals. Most of the industries shows interest in these polymer composites than the metals because of their advanced properties and their easiest way of manufacturing processes. In this project natural fiber reinforced polymer composites (NFRPCs) were fabricated using hand layup method. This project aims at investigating the mechanical properties of the NFRPCs in order to fabricate this material by the cheapest and easiest way. Here three composite plates were manufactured, where Bamboo bark or (Bamboo Culm) and typha angustifolia (cattail) were used as reinforcing material and General epoxy resin was used as a strong adhesive material to bind these fiber. These three plates are to be compared. One of the plates is random chemical treated; the second is bi-directional chemically treated and the third plate is unidirectional chemically treated. The mechanical properties in this study include the tensile, impact strength and flexural modulus. The flexural test was taken at these plates and with the help of test’s results. Mechanical properties of the plates were compared and the plate which has more strength can be selected.

Vertical axis wind turbine is one of the types of savonius wind turbine; VAWT generates huge twisting moment when running under lower speed by wind. Savonius wind turbine is the self-starting turbine; it uses magnetic levitation principle to get high rotational speed for the Generator. Magnetic Levitation is the phenomenon in which anything can freely suspend in the air without any support with opposed of gravitational energy. This magnetic levitation occurred due to the repulsion between the two symmetrical poles. The strong levitation is occurred with the use of permanent magnets. This type of model is to show its greater efficiency in varying wind conditions as compared to the conventional horizontal axis wind turbine and contribute to steady growing popularity for the purpose of increased utilization in the recent future as a reliable source of power generation.
