Authors: Sudirman A 
Published: November 2019

Abstract
This study aims to examine a literature review on teaching innovations that in part continues to sustain certain key aspects namely curriculum and assessment innovations, innovational instructions, innovative pedagogical strategies, technological innovations, and innovative teaching materials. As critical issues in current trends of vocational education and training (VET), these componential parts determine how vocational teaching innovations are set to enhance breakthroughs in terms of student-centered learning and teaching activities, and to what extent technology-based interactions should not abandon a humanistic approach involving direct social interactions and engagement. The results of article reviews show that teaching innovations seek to promote vocational teachers’ professional services, so that they actively advance technological skills, competencies and digital technologies in the digital era (45%). Another finding also leads to an institutional policy that teaching innovations need massive changes in the online pedagogical dimension (30%) fully supported by technological devices within a conducive atmosphere of learning and teaching processes. In another perspective, vocational teachers play a vital role in implementing the curriculum and literacy development through contextual projects, cultural awareness and curriculum development (20%). In contrast, only one article (5%) reviews how a competency-based performance assessment obviously contributes to the students’ competence and teaching innovations. Regardless of this fact, vocational teachers are agents of innovations who keep prioritizing better academic development and innovative professional services.

Applied programmable ECU on an internal combustion engine single cylinder 600 cc for Student Formula Japan
Authors: Wayan Adiyasa I , Yudianto Aan , Kurniadi Ninda , Sutiman  
Published: November 2019

Abstract
Student formula competition requires modification of the intake manifold hole by 20 mm. The internal combustion engine used has a capacity of 600 cc and an intake hole of 45 mm. The intake hole reduction affects the performance of the internal combustion engine. The ratio of the amount of air that is too small causes a decrease in engine performance. Ignition remapping is needed and fuel injection on the internal combustion engine. In the remapping process, the ratio of air and fuel is adjusted to the needs. The standard ECU on an internal combustion engine cannot be remapped. So the standard ECU on internal combustion engines is replaced using Motec M400. The parameters on the engine are only added to the camshaft sensor to determine the ignition timing and injection. Other sensors such as throttle position sensor, manifold absolute pressure, intake air temperature sensor, and engine temperature are used to determine ignition mapping parameters, fuel injection, and compensation for cranking, idle, and acceleration requirements. Tests obtained ignition remapping and fuel injection on internal combustion engines using ECU.

Published: November 2019

Abstract
Good ride performance is one of the most important key attribute of a passenger vehicle. One of the methods to achieve this is by using continuously variable transmission (CVT). This is because a CVT has the capability of providing an almost infinite ratio within its limits smoothly and continuously. Motor with automatic transmission known as motor matic is now become widely used as main transportation. Easy to drive is the main reason to choose this type motor cycle. The mechanism of pulley axially movement controller based on centrifugal concept where the ratio of pulley totally depend on speed rotation of input shaft which is in line with the engine shaft. The effect of this system is there is no engine break during decline road condition. So that actually this motor cycle is not suitable for road with extreme decline condition. The purpose of the research is to design mechanism where the pulley movement can be controlled by the driver with the aid of electromechanical system. The design electromechanical of Single Acting Pulley Actuator (EmSAPA) Continuously Variable Transmission (CVT) utilizes combinations of DC motor system, gear reducers and power cam mechanisms to actuate primary movable pulley sheaves on the transmission shaft. The secondary pulley supported by spring provides a belt clamping force to prevent slips, while the secondary controls the rubber v-belt from slipping. This paper is also present comparison on mechanical linkage system which will actuate pulley to move axially.

Published: November 2019

Abstract
A situation in which the car is directly parked under the sunlight needs to be considered as one of unavoidable operating conditions.The thermal phenomenon perceived by car dashboard might affect its functionality. The biomechanical function of the dashboard focused on the thermo-structural evaluation due to the direct sunlight was numerically simulated and investigated in this work. Polypropylene was chosen as the main dashboard material.The aims are to evaluate the temperature distribution, stress distribution and structural deformation of a car dashboard subjected to direct sunlight and due to the outside air goes inside the passenger compartment through an air duct.The material yieldsa small temperature gradient due to both direct sunlight and air flow through the air duct.By imposing 400 W/m2 heat flux on the dashboard surface, the stress distribution mainly occurs in the part of the applied constraints and the air duct placement, which has maximum value 19.56 MPa. The displacement of the dashboard is 0.0357 mm which is chiefly experienced by the front-centre part of the dashboard surface.
The Effect of Air Pressure in the Electric Train’s (KRL) Braking System on Wheel Damage
Authors: Zulkarnain Akbar , Artha Wirawan Willy , Boedi Wahjono Hari , Puspitasari Aldoko Indah 
Published: November 2019

Abstract
A flat wheel is a kind of wheel damage occurring when the train wheels are dragged along the rail as the axle wheel’s rotation stops. The wheels will skid when the brake block force is greater than the train force. The equation for the wheel skid is (Fbrake > Ftrain), this applies when the wheels stop rotating, but the train still moves so that a flat spotmay appear. This study finds that the electric trains from the JR 205 seriesthat has many flat spots on its wheels are the M trains (70%). It also reveals that the percentage of the brake block pressure in the unloaded KRL is 130.4%. Provided that ɳ>ɳmax (100%), this condition does not meet the standard of the International Union of Railway or Union Internationale des Chemis de Fer (UIC). If the percentage of the brake block pressure (ɳ) exceeds 100%, the braking force will be greater than that of the axle load and this causes the skid. To overcome this condition, rechecking the braking force and providing additional equipment are needed to assure that the air pressure is controlled.

Published: November 2019

Abstract
Calculating fluid pressure number is important in designing a pipeline system. When fluid is passing through the pipe, the pressure number is decreased, resulting in the decreasing of height set by the pump. If the height of fluid pressure in the pipeline is higher than that set by the pump, the fluids will fail to deliver. This research used a Sanyo pump type P-WH137C with 125 Watt electrical power, 1.55 Ampere electric current, 220V-50Hz voltage, maximum capacity 30 liter/minute with maximum flow height on 30 m and maximum water temperature at 45°C. This research aimed to find out the loss of water pressure’s height on two plastic pipes (paralon) sized 0.5 inch with 177 cm long and another one sized 0.75 inch with 102 cm long, each of which has one elbow and uses two valves.
