Handbrake of a vehicle is the most important thing in a safety system in maintaining theposition of the vehicle in its stop position. The hand brakes function to brake or lock the rearwheels mechanically through the connecting rods and cables. The hand brake is also to parkthe vehicle on a down/climb road. In order to facilitate the ability of four-wheeled vehicles whenstopping on the ramp due to traffic jams, a special wheel locking system is used on the ramp. Ina one-way wheel shooting system when a four-wheeled vehicle stops on the ramp, the systemlocks the wheel when the wheel rotates slightly backwards without having to pull the handbrakelever. Therefore, this research aims to describe how the work of the one-way wheel lockingsystem when on the ramp of a four-wheeled vehicle. At the design of this system researchersmake prototype as a simulation system that is approaching similar to the shape of componentsof a four-wheeled vehicle. Researchers perform test system work when the prototype movesforward and backwards to find out if the system is capable of locking the wheels when the moveis backward and release the locking wheel when moving forward without using the hand brake.Using a one-way wheel locking system is expected to facilitate the driver in driving four-wheeledvehicles on the ramp without having to use the hand brake.

The hospital information system has been regulated in Law Number 44 of 2009 concerning Hospitals. The law states that every hospital is required to record and report all hospital operations in the form of a hospital management system. In this regard, the research conducted at Wangaya Regional General Hospital, Denpasar City, aims to determine the performance calculation of the fiber optic network design at the hospital so that SIMRS implementation can be carried out optimally. This research uses Optisystem 7.0 simulation to determine the performance of network design at Wangaya Regional General Hospital, Denpasar City. Optisystem simulation with MMF OM4 cable produce a power receive value greater than allowable minimum receiver sensitivity, that is -11.1 dBm. The BER value obtained from the Optisystem simulation is less than 1x10-9 which indicates that the value has met the adequacy of the standard BER value in fiber optic networks. However, the Q-factor value obtained in the simulation is greater than the optical communication standard, that is 6. This design is feasible to implement using MMF OM4 cable from the results of testing with Optisystem simulations.
