Abstract

Research has been carried out to further investigate specifically the effect of sand powder, both the size of the sand grains and the thickness of the sand powder on the photodetector output as an advanced study of the single-mode optical fiber microbending loss theory in sand grains to pressure. This was done to investigate the response of optical fibers due to microbending loss to the load and determine the size of the sand particles that are most effectively used as a compiler of load sensors. The principle works to test the response of load sensors based on single-mode fiber optic microbending loss in the form of photodetector output when given a large variety of pressure. The method used in this research is to observe the reduction in the intensity of the light transmitted through optical fibers in the form of a voltage drop that is read by MMD that is connected to the photodetector. The reduced light intensity shows that the load sensor experiences optical attenuation of the laser as a light source with a wavelength of 1550 nm and a power of 1.47 mW. Microbending loss is caused by mechanical pressure that can change the direction of optical signal transmission and the radius of the curve is equal to or less than the diameter of a bare optical fiber. Observations were made using 12 load sensors with variations in the size of the sand grains in each diameter of the hose. The results of this study obtained the size of the most effective grains of sand providing microscopic curvature in the optical fiber that is 0.05 mm in terms of the correlation between the response of sensors with various diameters to changes in pressure.

Abstract

Instrumentation for monitoring natural disasters as an integrated early warning system has been widely developed and placed in areas that are estimated to be prone to natural disasters to help the government and the community. The purpose of this study is to take pre- and post-disaster measures to reduce losses experienced. However, the placement of these monitoring instruments has many shortcomings, one of which is the theft of the main components of the power supply and the battery used to activate the instrument. An alternative technology to solve this problem is to rely on power transmission with fiber optic-based light. The laser will be sent to the location using fiber optics which is then emitted to the solar panels so that the laser is converted into electrical energy. The power produced by an 810 nm laser-illuminated solar panel with a power of 140 mW is 7.76 mW. The power to produce an 810 nm laser must provide the same power as a monochromatic solar panel, which is illuminated by the sun's intensity at 25.395 mW.

Abstract

Abstract The type and technique of feeding is the main thing related to the acceleration of livestock development but almost most of the farmers do not pay much attention to the type and quality of feed given to their animals. Therefore, researchers designed the farm animal scales by creating an optical fibre-based sensor and utilizing the Arduino IDE software system for the purpose of making animal farmers aware of the weight information of their animals. The design of the scales has been done in the laboratory of Optoelectronics and Instrumentation, Physics Research Center of Indonesian Institute of Sciences (LIPI) Serpong. The optical fibre sensor system with the received light intensity output was then transmitted by the photodetectors and then Analog to Digital Converter (ADC) process using the Arduino Software. Result of sensor characterization with varying diameter rubber hose with high sensitivity obtained sensor with diameter of 3.1 cm and 2.6 cm. The test results showed that the sensor with a diameter of 3.1 cm was able to withstand pressure of 3.1 kg. F/cm2 or a load equivalent of 905.2 kg.
