CV. Handika Karya is a private mining company that focuses on andesite mining and operates in Hargorejo Village, Kokap, Kulon Progo Regency. To ensure the achievement of production goals, the exposure action is carried out through a blasting process. The use of the blasting method can cause a blasting effect due to ground vibrations and has the potential to cause damage to surrounding buildings. Civilians were within a 200 m radius of the explosion site. Controlling the resulting vibrations is essential to ensure the comfort of nearby civilians. The measurement location is divided into four areas considering direction, distance, elevation difference to the slope face, and the presence of buildings. After conducting research to determine the value of peak particle velocity (PPV) and the value of peak vector sum (PVS), there are incidents where the PPV value exceeds 3 mm/s and the PVS value exceeds 5 mm/s, which has exceeded the specified limits. Therefore, an updated review of seismic wave values is necessary. Data analysis was carried out using Scaled Distance Theory with the parameters of the distance from the blasting location to the measurement location and the maximum mass of explosives, using a safe limit value approach according to SNI 7571:2010. The first objective of this research is to determine the maximum amount of explosive mass that can be used for blasting while maintaining a PPV value of less than 3 mm/s within a radius of 200 m from the blasting location. After the analysis, it was discovered that the maximum mass of explosives was 83.4 kg/delay. The second objective is to determine the effect of ground vibrations at various measurement locations.
