Abstract

The presence of water in mining activities is common, especially in tropical areas that have high rainfall, such as the research location at PT ANTAM Maluku Utara at the Moronopo Site. While the sump maintenance needs to be considered so that the sump can accommodate the incoming discharge. The purpose of this research is to calculate the total discharge entering the mine and to design the dimensions of the sump according to the incoming water discharge. The research method used is the Gumbel method starting from the analysis of rainfall data at the research location starting in 2004-2013 and then continuing with 2019-2020 data, the planned rainfall value is 96.56 mm/day, rainfall intensity is 15.63 mm/day hours with a rain return period of 25 years and a hydrological risk of 18.46 % and the total inflow of mine water is 17,556 m3/hour. After calculating the sump capacity in the Danis 2 area, it still has not accommodated the incoming discharge with the remaining unaccommodated discharge of 2,319.1 m3/hour.

Abstract

Building damage can be caused by disasters such as earthquakes, landslides, etc. To minimize the fatality, the identification of buildings is needed to know the condition of buildings and whether the construction of buildings is able to endure if the disasters happen. This research uses the Rapid Visual Building (RVS) method to identify the building condition. The data are collected from  Kalirejo, Kulon Progo. The survey is conducted by taking a simple building evaluation form (typical of the walls ) based on RVS data. The field assessment results are distinguished into several factors that affect the condition of typical building walls: the foundations, structures, walls, and roofs of the 11 categories on the assessment form. From the data obtained, it is used to classify the building condition using Fuzzy Soft Set. The results show that the classification has been made with good performance in terms of accuracy, precision and time response. The accuracy and recall are close to 100% with above 50% of prevision average and time response is quite 0.0051 second. Thus, it can be used to  predict the condition of buildings accurately.

Abstract

This research focuses on the distribution of andesite and breccia rocks in East Java, Indonesia, specifically in Morang Village, Madiun Regency, through geoelectric resistivity measurements. This study aims to enhance geoelectric interpretation from 2D to 3D, providing high accuracy in target positioning for potential building material resources. By employing a dipole-dipole configuration with electrode spacing, the resistivity values of subsurface rocks were analyzed to classify the types and distributions of building materials, such as andesite and breccia. Data was collected through field measurements and geological surveys, followed by inverse modeling using the least squares method. The results reveal that andesite, with resistivity values above 1000 Ωm, is distributed predominantly in the southeast-northwest trend at a depth of 10–15 meters, while breccia, with resistivity values between 600–900 Ωm, is found at various depths closer to the surface. The geological interpretation suggests that the southeast-northwest orientation may correlate with an ancient basin structure, which directed lava flow during past volcanic activities, forming these rock layers. This study contributes valuable information for local infrastructure planning by providing data on accessible rock resources essential for construction. The application of the 3D geoelectric model offers an effective tool for environmental assessment and mineral exploration, promoting sustainable resource management.

Abstract

This study evaluates the effectiveness of the Induced Polarization (IP) method in identifying mineral presence within the Pacitan region through a detailed case study utilizing 2-dimensional (2D) interpretation of crossing lines. The Pacitan region, with its diverse geological structures, offers an ideal test site for assessing the IP method's capabilities in mineral exploration. By conducting extensive IP surveys and integrating the data with geological and geophysical information, distinct anomalies indicative of mineralization were identified. The results demonstrate that the IP method is highly effective in detecting subsurface minerals, providing a reliable tool for exploration. The 2D interpretation of crossing lines significantly improved the accuracy of anomaly detection and offered detailed insights into the spatial distribution of mineral deposits. Based on the IP survey results, a large resistivity anomaly is located at a distance of 40 metres from the starting point of measurement with a depth of 2-20 metres and a diameter of about 40 metres. Meanwhile, the chargeability anomaly is at a distance of 30 metres from the starting point with a depth of 4-24 metres and a diameter of about 30 metres. When observed from each analysis of line 1 and 2, the cross results can identify resistivity and chargeability anomalies very accurately. This research highlights the potential of the IP method as a non-invasive, cost-effective approach for mineral exploration, particularly in geologically complex regions like Pacitan. The findings underscore the method's utility in enhancing mineral prospecting efforts and contributing to more efficient exploration strategies.

Abstract

This study employs integrated geophysical methods to analyze the spatial distribution and subsurface geometry of andesitic rock formations in the Mujil Hill area, Kulon Progo, Yogyakarta. Electrical resistivity imaging (ERI), using a dipole-dipole configuration, was conducted to identify high-resistivity zones (>1000 Ωm), which are interpreted as fresh andesitic intrusions. These zones are consistently found at an average depth of 10 meters, embedded within moderately resistive volcanic breccia. Near-surface layers with low resistivity values (<100 Ωm) are associated with weathered volcanic deposits or unconsolidated soil. To enhance subsurface structural interpretation, resistivity data were complemented with gravity modeling, providing a more comprehensive geological assessment. The results confirm the lateral continuity and shallow emplacement of andesite bodies, highlighting their potential as a local source of construction material. This integrated geophysical approach supports sustainable mineral resource development and aligns with the objectives of the regional economic empowerment program, contributing to the responsible utilization of local geological resources.

Abstract

The proposed study area is located approximately 1.9 km southwest of the main cement plant in Tuban, Indonesia. This research aims to evaluate the rippability characteristics of the limestone formation underlying the planned development site. The assessment is based on data obtained from a geotechnical borehole investigation (CR-1), integrated with previous subsurface exploration results. The site is designated for shallow foundation systems designed to withstand bearing pressures ranging from 300 to 800 kPa. Subsurface conditions are characterized by karstic limestone with complex hydrogeological features. The limestone exhibits high sensitivity to water infiltration, dissolution processes, and mechanical property degradation under saturated conditions. Significant spatial variability in rock mass quality and strength is observed over relatively short vertical and horizontal distances. The uppermost layer comprises residual lateritic (red) soil derived from in-situ weathering of the underlying limestone. The presence of limestone gravels and boulders within the residual soil indicates a transitional interface between the overburden and the more competent limestone strata. The limestone formation consists of heterogeneous materials, including highly porous honeycomb-textured rock and relatively intact, sound limestone, distributed irregularly across the site. This heterogeneity results in considerable variability in mechanical strength and excavation response. The findings provide essential insights into the rippability behavior of the limestone and its implications for foundation design and construction planning in karst environments.
