Abstract

Multi-face detection presents a significant challenge in computer vision, especially in environments with limited hardware resources. This study compares the performance of three multi-face detection methods—Haarcascade, Dlib (HOG and CNN), and RetinaFace—using a subset of the WIDER FACE dataset in a CPU-only environment without GPU acceleration. The experiment was conducted in two stages using a total of 300 images from the WIDER FACE dataset, which reflect real-world variations such as pose, scale, illumination, expression, and occlusion. Performance evaluation was carried out using precision, recall, F1-score, accuracy, and processing time as metrics. The results show that RetinaFace consistently outperforms the other methods, achieving superior metrics in Recall (0.92), F1-score (0.93), and Accuracy (0.88) on Subset A, and leading across all metrics on Subset B. While Dlib-CNN demonstrates high detection performance, it suffers from very slow processing time. In contrast, Haarcascade delivers the fastest processing speed but performs poorly in terms of evaluation metrics. The experiments also reveal that RetinaFace is the most consistent and reliable method based on standard deviation values of precision (0.01), recall (0.11), F1-score (0.07), and accuracy (0.11). Overall, this study contributes valuable insights for selecting efficient face detection methods under constrained resource conditions.

Abstract

Flores Island is vulnerable towards natural disasters. Therefore, it requires an effective disaster warning ma-nagement. In this context, schools play an important role in disaster warning system. However, not all schools implement Disaster Risk Reduction (DRR) procedures effectively. Therefore, efforts are needed to improve disaster warning system among schools by integrating the three pillar principles, which include safe facilities, effective disaster management, and resilience education. This study aims to understand the state of school readiness in the Flores region and assess the extent to which these schools apply the three pillar criteria for school disaster warning system. The research method used is a qualitative descriptive ap-proach, with data collection through an open questionnaire distributed using Google Forms. The result showed that the locations of the respondent's schools are spread across the most disaster-prone areas of Flo-res, especially along the coastal areas. In addition, there are still many schools in the region that have diffe-rent levels of understanding and awareness regarding to disaster warning system. Based on that issue, the program for activating the disaster warning system in school area is very important to apply and can increase public awareness of disaster warning system. To achieve that idea, a collaboration between school commit-tees, external parties, and the Flores community is essential to strengthen the school infrastructure and to build an effective response towards potential disaster risks and threats.

Abstract

In November 2024, the eruption of Mount Lewotobi Laki-laki on Flores Island, Indonesia, resulted in the release of substantial volcanic aerosols, including sulfur dioxide (SO₂) and volcanic debris. These aerosols impacted the environment, health, and aviation activities. The objective of this investigation is to examine the temporal and spatial dynamics of volcanic aerosols by employing the Absorbing Aerosol Index (AAI) in conjunction with TROPOMI satellite data (Sentinel-5P). The methodologies employed are as follows: spatial-temporal analysis with Google Earth Engine (GEE), aerosol dispersion simulation with the HYSPLIT model, and data processing with the Sentinel Application Platform (SNAP). The results indicated a substantial increase in volcanic activity from November 8th to 11th, 2024, as evidenced by an ash column that reached a height of as much as 10,945 m. The distribution of aerosols was influenced by atmospheric dynamics, with high concentrations observed in the vicinity of Mount Lewotobi Laki-laki and extending to the east-southeast. Although the level of volcanic activity declined in late November, aerosol concentrations were still detected in the atmosphere. This investigation offers critical insights into the distribution of volcanic aerosols during the eruption and its effects on disaster risk mitigation and air quality. It is anticipated that these discoveries will facilitate the implementation of more sustainable and effective risk management strategies for volcanic eruptions.

Abstract

Over 30 years, the Flores region experienced earthquakes with Mw >7 twice, namely in 1992 and 2021 at shallow depths <60 km. However, the behavior of the aftershocks accompanying the quake has yet to be studied in detail. This research aims to compare the behavior of aftershocks after the main earthquake. This research uses three-lifetime analysis functions, namely, Wilber3, Mustang Web Browser, and comparison of Probability Density Function Hazard. The data used comes from IRIS data and BMKG Online Data. Through graphical analysis, it is known that the data for the time difference for aftershocks follow the RMS distribution, indicating that the Flores Sea aftershock on 12 December 1992 occurred with high intensity on the 3rd and the 6th day after the main earthquake. Meanwhile, the aftershocks in the Flores Sea on 14 December 2021 tended to occur with a more even intensity during the observation period, but the power returned to high on the 7th day
