Penerapan Data Mining Dalam Memprediksi Gempa Bumi Di Nusa Tenggara Timur Dengan Menggunakan Metode Naïve Bayes Dan K-Means Clustering
Get PDFEarthquakes are natural disasters that are difficult to predict bot in terms of timing and magnitude. The cause of earhquakes can originate from inense shaking due to the accumulation of energy within the lithosphere, which is then released onto the Earth’s surface with a certain magnitude. Indonesia, as a country located in the Ring of Fire and at the intersection of three major tectonic plates (Eurasian, Indo0Australian, and Pacific), frequently experiences earthquakes both tectonic and volcanic in nature, resulting in high damage and casualties. The process of earthquake occurrence is highly complex and difficult to directly observe due to the intricate interactions between materials and energy beneath the Earth’s surface. To date, there is no precise theory to accurately predict when and where earthquakes will occur. In this context, researches utilize earthquake data from the East Nusa Tenggara islands and apply data mining methods such Naïve Bayes and K-Means Clustering. Naïve bayes used to predict future earthquake events based on historical data using probabilities and statistic. K-Means Clustering in employed to group earthquake data into cluster based on specific characteristics. The research result indicate with a prediction vale of 0.907 and a confusion matrix achieving 90.74%. this indicates that 2022 had the highest number of both mild and major earthquakes in the past 11 years. Analysis using K Means Clustering also identifies patterns in the number of earthquakes each year, such as in 2022 where the clustering resulted in C1 with 67 mild earthquakes, C2 with 7 major earthquakes, and C3 5 mild earthquakes. Thus, this study demonstrates that the combination of Naïve Bayes and K Means Clustering is effective for predicting and analyzing earthquake events in this region. This research provides a foundation for further development in enhancing prediction capabilities and risk mitigation againts earthquake disasters in the future

No full textReinforced concrete is a composite material consisting of concrete and steel reinforcement. This combination provides optimal strength to the building structure.
Concrete is strong in compression and steel reinforcement is strong in tension. One of the factors that affects the corrosion of rebar is the thickness of the concrete
cover. This study aims to evaluate the effect of variations in concrete cover thickness on the corrosion rate of steel reinforcement and the compressive strength of
concrete.

The test specimens consist of 15 pedestal columns measuring 15 x 15 x 30 cm. The variations in concrete cover thickness used are 10 mm, 15 mm, and 25 mm. The process to accelerate corrosion on the reinforcement steel was carried out by immersing the test specimens in a 3.5% NaCl solution for 10 days using the galvanostatic method. The compressive strength test was conducted according to ASTM C39 (Determine the compressive strength of cylindrical concrete specimens such as mold cylinders and drill cores) and the corrosion rate test according to ASTM G31 (Standard Practice for laboratory immersion corrosion testing of metals) on the rebar. The research results show a correlation between the thickness of the concrete cover and the corrosion rate and compressive strength. The thicker the concrete cover, the lower the corrosion rate occurring on the steel reinforcement. The test
specimen with a cover thickness of 25 mm showed the lowest corrosion rate (5814 mpy) and the highest compressive strength (392.00 kN). Conversely, the test
specimen with a cover thickness of 10 mm experienced the highest corrosion rate (10315 mpy) and the lowest compressive strength. (322,50 kN
