    Abstract

    Determine configuration of landslide sensor based on glass fibre optical multi-monitoring model has been researched. This sensor developed using intensity modulation principle macrobending loss. Mainly part of this sensor consist of displacement fibre sensors, mechanical displacement sensors, and Short Messaging Service (SMS) gateway equipped with a siren. This sensor can send a signal SMS when critical condition has been reached. Optical fibre sensors made by wrapping a glass optical fibre around a holey elastic cylinder. The elastic cylinder made with diameter of 1 cm; 1,5 cm; 2 cm; & 2,5 cm. The number of turn for each diameter was varied from 1 turn to 10 turns. A coil fibre gave pressured would made a changed of output light intensity. This changed would read by interface program has made with LabView 2013. From the experimental results, we suggest a configuration with 2,5 cm coil diameter and 10 turns has best sensitivity for applied to sensor systems. The configuration looked from linear graph trend about relation between light loss and displacement. The sensor has been simulated on landslide model and it could sent a warning SMS when critical displacement reached, for example 4 cm. This work occured too in every point of system.
