Abstract
Construction installations built with stainless steel are the main choice of the list of materials that can be used for construction near the sea. With the recent discovery of tungsten inert gas (TIG) technology, construction with stainless steel can be realized. In some cases stainless steel welding joints are made by connecting with stainless steel of different types without regard to the strength generated especially if experiencing corrosion in this case corrosion due to sea water. In this study the tensile strength of stainless steel combination joints of type 304-201 was tested and compared with similar joints of types 304-304 and 201-201. The effect of seawater corrosion on the tensile strength of stainless steel joints was also examined. This research found that the highest tensile strength is 304-304 joints followed by 304-201 combination connections and the lowest is 201-201 joints. The effect of seawater corrosion is known to reduce the tensile strength of all types of joints.

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

Abstract
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.

Abstract
Bicycle is one of the most popular transportations in the world because it is emission-free and can be used by everyone. Bicycle is always evolving in accordance with the latest technology. Various designs have emerged to change the shape of the bicycle to the present. Design is important in making new concepts to overcome existing problems. The design of a bicycle transmission system without a chain intends to overcome the problem of maintenance needs of a chain-equipped bicycle. The design of the bicycle chain transmission system was changed using a four linkages mechanism. Two types of models were made using the same principle. These two types of bicycle system designs use a four linkages connecting mechanism. The system motion simulation is created using Fusion 360. Motion simulation of this system shows that bicycle transmission without chain works properly. The two types of designs will be compared based on the force needed to move the bike and the results of the simulation.

Published: December 2020

Abstract
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.

Abstract
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.

Abstract
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.
