“…Landslide monitoring has developed using optical fiber. The optical fiber as the sensor can be used in various fields of measurement, including measuring solution pressure, temperature [6], vibration [7], displacement [8], load and crack [9][10][11], stress [12], fuel detection [13], health [14,15], etc. Optical fiber is safe to use, has a high speed of light transmission, is resistant to corrosion, is not sensitive to electromagnetic waves, and does not conduct heat.…”

The research has measured the landslide using a displacement sensor based on Glass Optical Fiber (GOF) and Optical Time Domain Reflectometer (OTDR). The sensor manufacture process consists of various materials, structures, configurations, diameters, and directions. The sensor is made using GOF with a single-mode structure and single mode-multimode-Singlemode (SMS) structure. Each system is given a variety of configurations, namely gamma, bowknot, and three loops configuration. Each arrangement is provided a variation of the indentation diameter in three displacement directions. The test results will be read as the power loss on the OTDR in dB units. The results obtained were then compared between two materials, two structures, and directions. Displacement resulting landslides and changes to the sensor, causing power losses, and affecting the characteristics of each sensor. We found the best measurement results with the sensitivity value of 0.241 dB/mm and the resolution value of 0.004 mm. The displacement sensor has been made for measuring landslide in the laboratory-scale simulation based on GOF and OTDR with easier fabrication, easy operation, high sensitivity, better resolution and can be connected to a computer

Indonesia’s geographical conditions are one of the causes of land movement. This land movement can occur due to the movement of rock masses, soil, or debris material making up the slopes. The stability of a slope is influenced by several parameters such as material, soil strength, slope angle, climate, vegetation, and time. In Indonesia, land movement disasters are placed the third rank of natural disasters that occurred throughout 2021. Thus, the development of a land movement detection system is very important for monitoring land movement disasters. In this research, a land movement detection device was developed using the ADXL 335 accelerometer sensor and fiber optic. For data acquisition, Arduino Uno, LEDs, and photodetectors were used. Arduino Uno was used to convert analog signals to digital. In addition, LEDs were used as light sources, and photodetectors were used as a receiver. Changes in the output voltage due to macrobending loss are obtained when the curvature changes due to the pendulum system. The results of the study show that the average acceleration values on the x, y, and z axes of the accelerometer sensor are 0.118 g, 0.925 g, and -2.494 g. The maximum land displacement movement that can be represented by fiber optic is 4 cm. Further, the combination use of accelerometer sensors and fiber optic can show the magnitude of the force that causes displacement, the direction of land displacement, and the magnitude of the land displacement that occurs.
