On a laboratory scale, water quality measurements generally use the degree of acidity (pH) and wather index. This study aims to implement simple physics equations with the tools we make by applying the principle of light diffraction. One of the parameters to determine the level of water quality can ...

Split stone is a type of irregular stone formed from sedimentary rock deposits and sandstone due to weathering and the influence of abrasion in rivers, so split stones are formed. The utilization of split stone as an embankment can be optimized by varying the angle of inclination of the embankment i...

The bilinear interpolation method is generally used to improve images that have noise. However, in this research the bilinear interpolation method will be used to determine the weight value of a digital scale designed with four load cell sensors. Data collection was carried out by placing loads at n...

Activated carbon (AC) combined with TiO2 photocatalyst can be used as a hybrid material in water purification. However, the dispersed–composite of AC/TiO2 in water needs additional treatment to obtain clean water, so it is considered less effective. This study aims to deposit AC/TiO2 on polystyren...
