Abstract

AbstractAstra Isuzu Sales Operations Karawang branch is the official workshop of the Isuzu brand which is a PT network company. Astra International – Isuzu Sales Operations (ISO) which provides Analysis, Overhoul, Adjusting, Replacing, Retrofit, Periodic Service, Maintenance and so on. Lead time is an important factor to measure how long the work process takes to determine quality, of course, in an industry, time is money, the longer the work takes, the more time it will hamper other work. The problem that the author found was that it was difficult to remove the reverse switch sensor on the Isuzu Giga unit because its location was very difficult to reach using tools and very limited space. So far, technicians have used the Fukung 24 tool to remove it, but it took quite a long time, namely around 35 minutes, from As a result of the analysis carried out, the root of the problem can be identified, and to overcome this the author created the SST Switch Reverse Tracker Sensor to simplify and speed up the work with the processing time using the SST Switch Reverse Tracker Sensor being 8 minutes, making the work more effective and efficient so that the productivity of technicians and Workshop stalls are maximized and wasted time is lost.ektif dan Efisien, Sensor Switch Mundur, SST

Abstract

For 91% of the world's population, the air environment is very bad because it exceeds the threshold set by the World Health Organization. The global transportation sector is experiencing major changes towards sustainability and innovation because it is one of the contributors to air pollution. This research focuses on convertible electric motorbikes which have many advantages compared to conventional motorbikes such as having greater torque, minimal maintenance, and emitting no exhaust emissions. The method used in this research is analyzing the forces that occur on conventional motorbikes, analyzing wheel rotation speed, analyzing gearboxes and CVTs as a starting point for determining the type and specifications of the electric motor used, designing the left crankcase for the electric motor mount, designing the mechanism. construction of a connecting jow-clutch between the electric motor and the primary pulley mounting shaft, making a prototype of the left crankcase along with the components of the clutch mechanism and the primary pulley mounting shaft, and carrying out experimental testing on a motorbike. Replacing parts only takes 2 hours to convert a motorbike of this type. The results of static experiments in this research are that the effective power produced by a converted motorbike is 593.61 Watts at a torque of 1.71 Nm at 3317.63 rpm. In the dynamic experimental test, the convertible beat motorbike from a full battery position could cover a distance of 15.35 km until it was finished with a driver and passenger load of 146.5 kg. The convertible motorbike can accelerate from 0 to 51.43 km/h in 14 seconds.
