Abstract

This study was conducted to identify the presence and distribution of pumice resulting from the 1257 AD eruption of Mount Samalas in the Ampenan and Sekarbela Districts of Mataram City. The research is significant because pumice serves as a volcanic indicator that greatly influences soil characteristics and the local environment. The study aims to map the distribution of pumice and to examine its subsurface dispersal, particularly in coastal areas. Georadar and geoelectric resistivity methods were employed—two geophysical techniques that measure the electrical response of the subsurface, thereby detecting changes in resistivity and conductivity indicative of volcanic material such as pumice. The results reveal that pumice is uniformly distributed at depths of 0–9 meters and is intermixed with gravel, silt, and sand. In the study area, the soil layer is predominantly sandy, likely due to its coastal location. This research underscores the importance of using geophysical methods to map the distribution of volcanic materials in shallow layers, especially in areas affected by volcanic eruptions.

Abstract

Retraction Notice This article has been retracted at the request of the Editor-in-Chief after reviewing the available evidence and verifying the report received. The article entitled “Identification of the Presence of Pumice Stone Based on Georadar Data and Geoelectric Resistivity Data in Ampenan District and Sekarbela District, Mataram City” published in Jurnal Ilmu Fisika, Vol. 17 No. 1 (March 2025), was found to have a similarity level of approximately 94% with another article previously published in Lambda: Jurnal Pendidikan MIPA dan Aplikasinya, Vol. 5 No. 1 (April 2025), titled “Kombinasi Metode Georadar dan Geolistrik Resistivitas untuk Mendeteksi Keberadaan Batu Apung di Kota Mataram.” The research data (Georadar and Geoelectric data) belong to Universitas Mataram and were used without permission from the data owner. Therefore, Arsi et al., as the authors of the article published in Jurnal Ilmu Fisika, are considered to have published the article without authorization from the rightful data owner. As a result, this article has been formally retracted from the Jurnal Ilmu Fisika archive.
