Abstract

The Western Sunda Arc is an active tectonic zone formed by the subduction of the Indo-Australian Plate beneath the Eurasian Plate. The tectonic zone hosted for 83 active volcanoes, including Mts. Sinabung, Krakatau, Tangkuban Parahu, Merapi, and Semeru. The dense volcano concentration and high volcanic activity cause complexity in monitoring and observation processes. Segmenting volcanoes by location and tectonic setting is necessary to simplify the disaster monitoring and enhance mitigation efforts through focused observation areas. This study focuses on the segmentation of the volcanoes distributed at the Sunda Arc in Indonesia by analyzing the satellite-derived geological lineaments and land surface temperatures. The Sunda Arc is a complex volcanic chain that spans through Sumatra and Java Islands and lies in an active tectonic region. Remote sensing data and advanced geospatial techniques were used to examine geological lineament patterns and surface temperatures along the volcanic arc and the results were validated through fieldwork. Moreover, Shuttle Radar Topography Mission (SRTM) and Landsat 8 OLI/TIRS imagery were applied to achieve accurate lineament extraction and surface temperature anomaly detection. Lineament density was also computed through the modified Segment Tracing Algorithm (mSTA) to identify the fault zones and structural discontinuities in order to ensure better regional geological understanding. Subsequently, land surface temperature analysis was used to classify thermal anomalies and this led to the differentiation of natural volcanic sources from ground surfaces. These parameters were integrated to segment the volcanoes of the Sunda Arc into nine zones. Each zone was presented by average lineament density from 207.83 km/km2 to 166.06 km/km2, land surface temperature from 23.36 °C to 28.65 °C, angle of subduction slab from 22.871° to 38.007°, and lineament strikes from N 330° E to N 260° E. The zones were later discussed relative to the gradient of the Sunda Arc subduction slab as a form of contribution to the existing knowledge on geothermal dynamics, tectonic processes, and volcanic hazards beyond the region.

Abstract

Geological mapping for volcano products that has just erupted will give important basic information to understand the eruption characteristic and the hazard mitigation that can be done. Difficult terrain and high danger around active volcano cause geological mapping hard to be done using direct observation method. To give another solution for the problem, we try to explain digital volcano products mapping using supervised classification method from field data that still be reached. Image data selection with atmospheric correction is the important factor to get high map accuracy. Supervised classification method that used in this research is Minimum Distance Classification. This method uses average vector for each ROI and calculates Euclidean distance from every pixel for each class, so every class can be distinguished well and precisionly. Geological observation is done before classification process by choosing 140 observation point that spread in the east of Agung Volcano. Geological data consists of lithology, correlation, and the mechanism of the rocks that used as the reference in the determination of class for classification from Landsat 8-OLI/TORS image. The research area is located on the east of Agung Volcano which has 60 km2. It is located between Kubu District, Abang District, and Bebandem District, Karangasem Regency, Bali Province. Supervised classification can map products of Agung Volcano for area that can’t be reached around 324 km2. Verification process is done by comparing supervised classification result in research area with observation point at the field using Classification Accuracy Assessment method with result reaching 90%.

Abstract

This study examines the factors influencing Generation Z consumers' preferences for Cash on Delivery (COD) and their intention to continue using this payment method in Garut Regency, Indonesia. Despite the proliferation of electronic payment options, COD remains the predominant choice in e-commerce transactions. The research employs the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach to investigate the impact of three key factors on the intention to continue using COD: risk perception, trust, and ease of use. The findings reveal that ease of use and risk perception significantly influence the intention to continue using COD, while trust does not demonstrate a significant effect. These results highlight the critical role of user-friendly payment systems and perceived risk in shaping the payment preferences of Generation Z consumers. The study contributes to the understanding of consumer behavior in emerging e-commerce markets and provides insights for businesses and policymakers seeking to optimize payment systems for younger demographics.

Abstract

Although research on learning to write descriptive texts continues to grow, there are still few studies that systematically map the trends and directions of research related to the use of learning media. Therefore, this study aims to analyze scientific developments on the use of media in learning to write descriptive texts using a bibliometric analysis approach. Data were obtained from 200 scientific articles published on Google Scholar during the period 2020–2024, collected using the Publish or Perish application, and analyzed through VOS viewer based on quantity, quality, and structural indicators. The results of the analysis show eight main clusters of research topics, namely descriptive text writing skills, types of media, learning models, digital technology, and visual approaches to writing. The research trend has increased since 2020, with Padlet, Instagram, and serial images being the dominant media studied. However, after 2023, no new prominent trends have been found. Density analysis shows that the topics of "media" and "writing text" are relatively dense, while "methods" and "skills" are still open for further research. Thus, this study provides a comprehensive overview of the dynamics and development of research in the use of learning media for writing descriptive texts, and is an important reference for the development of studies in this field.
