Abstract

Landslides are a common disaster in Indonesia so that the necessary anticipation through the monitoring of areas prone to the development of instrumentation systems disaster. Design has been done measuring the physical symptoms of landslides using optical and electronic systems. Measured physical symptoms include a shift in soil, and soil strains. Shift in the electronic ground sensors made by using linear and potensio constan current source. The result of measurement is known that this sensor can detect a shift change of 0.5 mm with a maximum shift of 250 mm. Soil strain measured using a fiber optic brag grating (FBG), which changes the transmission peak of FBG was done by using the diode laser wavelength sweeping. Fiber brag grating is an optical sensor that works according to the resonant effect of a refractive index grating lattice, where the resonant wavelength is determined by the lattice distance. From this principle it is when the lattice spacing change due to the strain and temperature changes, the peak resonant wavelength will also change. Changes in the resonant peaks are measured to determine the strain or temperature measurement. measurement Simulation showed that the relationship between strain and change in peak wavelength is linear with slope (Δλ / ΔF) 1.41 nm / kNewton. Keywords: Extensometer, linear potentiometers, fiber Brag grating, landslides, system monitoring, disaster

Abstract

The growing demand for advanced coatings in industries such as aerospace and automotive necessitates materials with superior hardness, wear resistance, and thermal stability. Despite advancements in ternary coatings, research on binary Titanium Nitride (TiN) coatings remains limited, particularly in optimizing deposition parameters for lightweight aluminum substrates. This study aims to investigate the effects of sputtering parameters, specifically Ar:N₂ gas ratios and deposition durations, on the mechanical properties of TiN coatings on Al 6011 substrates. The optimized conditions (70Ar:30N₂ gas ratio and 60-minute deposition) yielded a 165% increase in surface hardness (88.92 HV) and a 54% reduction in wear rate compared to untreated samples. XRD and SEM analyses confirmed the dense microstructure and strong (200) phase orientation contributing to these enhancements. This research highlights a cost-effective and scalable approach to improving the performance of aluminum alloys, bridging the gap between fundamental studies and industrial applications.
