Abstract
As an increasing highly mobility and high traffic, the necessary of motorcycle is highly increasing. The condition makes user ride motorcycle with highly speed in highly frequency. Then, these conditions make motorcycle machine reliability is highly decreasing. Finally, it made machine is run to damage and maintenance cost to be high. Analog tachometer is an electronic instrumentation that proposed to solve these problems. Actually, instrumentation system of tachometer is an electromechanical system. A wire in a control unit is embedded into shaft of crank. Then, magnet in control unit will convert rotary machine energy into electrical energy with d’Arsonval meter. Current sensor and small variable resistor are the kind of sensor that are used in tachometer. Small variable resistor is used for tuning and recalibration. Utilization small variable resistor in tachometer circuit is make calibration and recalibration current sensing of electrical current that rectified by diode. Tachometer for counting rotation per minute (RPM) motorcycle machine is built up. The tachometer has capability to count RPM motorcycle machine 1,000 – 13.000 RPM. The range is reliable as an indicator for user to minimize motorcycle machine wearing.

Analog tachometer is an electronic instrumentation to count machine revolution based on time period – revolution per minute (RPM)
Summary
Motorcycle is a popular modern transportation in Indonesia because cheap and high mobility. Instrument based electronics circuit such as analog tachometer is used to give weathering or reliability indicator through showing rpm value of motorcycle machine for user. Qualitative and quantitative analysis are made with C++ in the platform software .Net. Reference [16] explains complexity fault detection process to detect fault of rotating machine because its non-stationery character and non-linear vibration since its operated. Reference [20] explains utilization of locality constrained linear coding with support vector machine (LLC-SVM) to detect machine fault with vibration as based parameter. LLC-SVM is used to identificate vibration signal and classfified into the kind of fault in the rotating machine Based on these researches, there are many information to support our proposed design, namely instrument facility design should be conformed to instrument’s function. Arduino as microcontroller is used to control signal output for tachometer
