Abstract

This document presents the PPMI Project 2023 conducted by the Research Group of Applied Geology. The research theme focuses on forensic geology for society, encompassing various sub-themes such as hydrogeology, engineering geology, geophysical exploration, geothermal exploration and management, and hazard mitigation. The objectives of the project are to apply these sub-themes of forensic geology to address physical problems in society.

Sub theme 1

In this report, you will find a comprehensive overview of the ongoing research activities and recent publications. The studies include the evaluation of a deep neural network model for rainfall anomaly analysis, analysis of chemical properties of groundwater and surface water, quantification of aquifer interaction using a numerical groundwater flow model, and more.

Sub theme 2

The project also involves reports in progress, technical notes, and abstracts covering diverse topics such as Tiga Danau Mahakam, offshore platform design and reliability analysis, primary-field data significance in regional planning, and hydrogeological studies in the Walini urban area.

The first paper under review focuses on the performance evaluation of a deep neural network model applied to the annual rainfall anomaly index in Indramayu, Indonesia. The second paper published discusses the chemical properties of groundwater and surface water along the Jilu River. The third paper presents an abstract on quantifying aquifer interaction using a numerical groundwater flow model in the Bandung groundwater basin.

Sub theme 3

Furthermore, several papers have been published, ranging from the geochemical investigation of geothermal conceptual models to the cultural traces of plantation industries and geological hazard assessments. Additionally, accepted papers address the establishment of GIS data repositories for multi-sectoral geoportals and integrated methodologies for urban flood mitigation

Several papers have been published, covering various topics. These include the geochemical investigation of the Tangkuban Perahu geothermal conceptual model, cultural traces of the Gutta Percha Cipetir plantation industry in Sukabumi Regency, and the assessment of geological hazard potential in Bukit Barisan Selatan National Park.

Sub theme 1

Moreover, a paper has been accepted for publication on a GIS data repository to support multi-sectoral geoportals. Additionally, another paper has been accepted that presents an integrated methodology for urban flood mitigation in Bandung, Indonesia. Lastly, it is worth mentioning that forensic geology is an emerging area of study in the field of geoscience.

Collaboration

This project operates in a collaborative scheme with the Atmospheric Science Group, Geodesy and Geomatics Group, and Civil and Environmental Group. Together, these groups contribute their expertise to enhance the research outcomes and address complex physical problems in society. The interdisciplinary nature of the collaboration allows for a comprehensive approach to forensic geology and fosters innovative solutions for societal challenges.

Benefits

Through their collaborative efforts, the group is able to enhance the research outcomes and broaden the scope of their investigations. By utilizing advanced techniques and methodologies, such as deep neural network models for rainfall anomaly analysis and numerical groundwater flow models for aquifer interaction quantification, they are able to gain valuable insights into the physical processes and phenomena that affect our environment. The research activities also involve the analysis of chemical properties of groundwater and surface water, as well as studies on hydrogeological and hydrochemical systems in urban areas.

The outcomes of this project are not only reflected in the ongoing research activities and publications but also in the potential for practical applications. The findings and methodologies developed by the group have the potential to inform regional planning documents, contribute to the design and reliability analysis of offshore platforms, support the establishment of GIS data repositories for multi-sectoral geoportals, and provide integrated methodologies for urban flood mitigation. By addressing societal challenges through forensic geology, the group is actively contributing to the betterment of our communities and the sustainable management of our natural resources.
