Abstract

Abstract. Kalirejo Village, Pengasih District, Kulonprogo Regency, is an area that is prone to landslides. The purpose of this study is to identify the weathering layer thickness, which is one of the triggering factors for landslides. This study was conducted using the seismic refraction method by applying two lines. Line 1 uses 24 geophones, has a distance of 1 meter between geophones, while Line 2 uses 24 geophones, has a distance of 2 meters between geophones. The results showed that the velocity of seismic wave propagation in the weathering layer for Line 1 was 400 m/s, and in the slip surface was 2,300 m/s. The weathering layer thickness on Line 1 is 7.6 - 9.8 meters and the slope is steep so that this location is predicted to have a potential landslide. While the velocity of seismic wave propagation in the weathering layer for Line 2 was 300 m/s, and in the slip surface was 2,200 m/s. The weathering layer thickness on Line 2 is at less than 2 meters, so this location is predicted not to have a landslide potential even though the slope is steep

Abstract

Indonesia is one of the countries located in the Pacific Ring of Fire, where three tectonic plates meet. This makes Indonesia very vulnerable to natural disasters such as earthquakes, volcanic eruptions, and tsunamis. These natural phenomena occur very frequently, as evidenced by events such as those that have occurred on the island of Sumatra. This study aims to classify earthquake data in the Sumatra Islands based on hypocenter using the Naive Bayes Algorithm. The study uses earthquake datasets specifically from the Sumatra Islands, which are divided into training and testing data. The results of the study indicate that classification can be performed using the Naive Bayes Algorithm based on three categories, ranging from shallow earthquakes, moderate earthquakes, to deep earthquakes.

Abstract

The development of big data technology has generated huge volumes of diverse data, creating challenges in detecting anomalies that could potentially affect decision-making. This research aims to examine the application of artificial intelligence (AI) in detecting anomalies in big data systems to support faster, more accurate and effective decision-making. The approach used includes the integration of machine learning algorithms, such as classification-based detection, clustering, and deep learning, in identifying abnormal patterns in large datasets. The research method involves real-time dataset-based simulations by measuring the performance of AI models using accuracy, precision, recall, and F1-score metrics. The results show that the application of AI can significantly improve the anomaly detection capability compared to conventional methods, with an average accuracy of 92%.

Abstract

This Community Service (PKM) activity aims to increase cybersecurity literacy among teachers and students as part of efforts to support digital transformation in education. The training was conducted online with an interactive approach, involving 50 participants from various schools in Indonesia. The material includes an introduction to cyber threats, mitigation strategies, and daily digital security practices. The evaluation was done through pre-test and post-test, accompanied by a participant satisfaction questionnaire. The results showed a significant improvement in participants' understanding, with an average score increase of 73%. The level of satisfaction of participants with the training reached the "excellent" category with an average score of 4.75 on a scale of 5. These findings reflect the effectiveness of the designed training methods. However, the limitations of digital infrastructure are the main challenge in implementing activities. This Activity has contributed positively to building cybersecurity awareness and literacy in the education sector. In addition to providing direct benefits to participants, this program is expected to be a model for similar training that supports the sustainable strengthening of digital literacy in Indonesia.Abstrak.

Abstract

Photocatalysis is one of the environmentally friendly technologies with great potential to address global issues related to pollution and the demand for clean energy. However, limitations of conventional photocatalyst materials, such as low light absorption and high electron–hole recombination rates, have hindered optimal efficiency. This review highlights the role of carbon-based materials as the latest innovation in enhancing photocatalytic performance. Various forms of carbon materials, including graphene, carbon nanotubes (CNTs), carbon quantum dots (CQDs), and porous carbon, have been shown to improve charge separation, broaden the light absorption spectrum into the visible region, and enhance the structural stability of photocatalysts. Literature analysis indicates that the integration of carbon with semiconductors significantly increases pollutant degradation efficiency, cycle stability, and the potential application in renewable energy production. Moreover, the utilization of biomass waste as a source of porous carbon opens opportunities for more economical, sustainable, and eco-friendly technologies. This article provides a comprehensive overview of research progress, performance enhancement mechanisms, and future development directions of carbon-based photocatalysts, which are expected to contribute to innovative solutions in the fields of energy and environmental sustainability.
