Abstract

This study aims to identify hydrothermal alteration zones in Lubuk Sikaping District, Pasaman Regency, West Sumatra, using Enhanced Magnetic Model (EMM) 2017 geomagnetic data developed by the National Oceanic and Atmospheric Administration (NOAA). The data processing stages include International Geomagnetic Referee Field (IGRF) correction, evaluation of regional and residual anomalies using Radial Average Power Spectrum (RAPS), reduction to the poles, analysis of magnetic anomaly values ​​with the geological conditions of the study area. The results show that residual magnetic anomalies are in the range of -7.09582 nT to 7.65333 nT. The results of the analysis of magnetic anomaly values ​​and geological conditions indicate that the high anomaly zone (3.12460 nT - 7.65333 nT) spread in the south and southwest is a mineralization zone. The moderate anomaly zone (0.07503 nT - 3.12460) spread in the central to northeast is a lithology preservation zone between magnetic igneous rocks and non-magnetic sedimentary rocks. The low anomaly zone (–7.09582 nT - 0.07503 nT) located in the north and northeast is a hydrothermal alteration zone. The presence of mineralization zones, lithology boundary zones and hydrothermal alteration zones indicates that there is a fluid migration path in this area. The hydrothermal alteration zone in Lubuk Sikaping District is associated with the Sarik-Gajah Formation which consists of volcanic rocks that have undergone alteration due to the presence of active structures of the Sumatran Fault System.

Abstract

A study has been conducted utilizing secondary geomagnetic data from the Enhanced Magnetic Model (EMM) 2017. This study aims to identify the potential presence and lateral distribution of laterite nickel minerals in Poli Polia District. The data processing stages include International Geomagnetic Reference Field (IGRF) correction, Reduce to Pole (RTP) transformation, and separation of regional and residual anomalies. Furthermore, analysis and interpretation are carried out by comparing the residual anomaly map to the regional geological map. The results of the RTP transformation obtained residual magnetic anomaly values ​​ranging from -0.8 nT to 0.7 nT with high anomaly values ​​ranging from 0.5 nT to 0.7 nT and low values ​​ranging from -0.8 nT to -0.6 nT. In the southwest of the study area there is a low magnetic anomaly zone surrounded by a low magnetic anomaly zone, while in the north it is the opposite. The results of data interpretation indicate that the high anomaly zone in the southwest is related to the presence of the Ultramafic Complex (Ku) composed of peridotite and serpentine rocks, while the low anomaly zone is interpreted as a prospective area containing laterite nickel minerals. Meanwhile, in the northern part, the low anomaly zone correlates with the Mekongga Complex (Pzm), which is composed of metamorphic and sedimentary rocks. The presence of a high anomaly zone in this area indicates the presence of geological features such as faults or joints that play a significant role in enhancing the local magnetic response.

Abstract

Indonesia is a country with significant potential for gold mineral resources, particularly in areas along the Sumatran magmatic belt. This study aims to identify the potential distribution of gold mineralization in Sangir District, South Solok Regency, using secondary geomagnetic data. The data used is the Enhanced Magnetic Model (EMM) 2017 model obtained from the National Oceanic and Atmospheric Administration (NOAA). Data processing was carried out through the stages of IGRF correction, calculation of total magnetic anomalies, separation of regional and residual anomalies and reduction-to-pole transformation (RTP) using Oasis Montaj software. The results show that the residual anomaly after reduction to the pole ranges from -1.0935 to 1.1861 nT. Based on local geological conditions, zones with low magnetic anomalies that develop in the central to western parts of the study area are interpreted as alteration and fracture zones that have the potential to become hydrothermal fluid movement pathways. The zone with moderate to high magnetic anomalies that developed in the eastern, east-central, and southeastern parts of the research area is interpreted as a response from high magnetic rocks associated with sulfide minerals (pyrite) and porphyry systems, so that the zone is identified as a prospective zone that has the potential to contain gold mineralization.

Abstract

The role of external oversight institutions in maintaining the integrity of the judicial system is becoming increasingly important in contemporary governance. However, there is often a significant gap between institutional mandates and public perceptions, resulting in diminished public trust in judicial institutions. This study proposes a conceptual model of Corporate Social Responsibility (CSR) adapted from the private sector for application to the context of state institutions, using the Indonesian Judicial Commission as a comprehensive case study. Using a qualitative exploratory approach, the study analyzes the Commission's constitutional mandate in depth, combined with a review of contemporary CSR frameworks to assess its applicability to public oversight functions. The findings suggest that the adaptive application of CSR principles—such as operational transparency, authentic public participation, and sustainable community empowerment—can significantly enhance institutional legitimacy and the effectiveness of external oversight. This study introduces a CSR model tailored to the context of state institutions, comprising three key interrelated dimensions: legal education and civic awareness, public advocacy and institutional socialization, and community empowerment through participatory governance. The study suggests that CSR is not simply a tool to enhance corporate image, but a vital and strategic instrument for strengthening public trust and accountability in the modern judicial governance system.

Abstract

Defamation in cyberspace has become a serious legal issue alongside the rapid development of information technology and social media. The widespread use of digital platforms allows information to be disseminated quickly, but also increases the potential for acts that harm a person’s honor and reputation. In Indonesia, defamation is regulated under the Criminal Code and specifically through the Law on Information and Electronic Transactions (ITE Law), which provides distinct legal mechanisms and sanctions for offenses committed via electronic media. A normative legal approach with descriptive-analytical methods is employed by examining statutory regulations, legal doctrines, and relevant legal literature to analyze the regulation and enforcement of defamation offenses in the digital sphere. The analysis shows that Article 27 paragraph (3) of the ITE Law serves as the main legal basis for addressing online defamation, with criminal sanctions regulated separately under Article 45. However, its implementation faces significant challenges, including differing interpretations among law enforcement officers, complexities in digital evidence, and tensions between protecting individual reputation and safeguarding freedom of expression. These obstacles indicate that legal enforcement has not yet functioned optimally. Strengthening the capacity of law enforcement authorities, improving clarity in legal interpretation, and enhancing public legal awareness are essential to ensure balanced, fair, and effective enforcement of defamation law in cyberspace.

Abstract

The research aims to analyze how far work discipline and work facilities influence the level of effectiveness of employee performance at Ibis Hotel Padang. The method applied in this research is a descriptive method with a quantitative approach. Data in the form of numbers was obtained through distributing questionnaires, and processed using SPSS version 26. The research results showed that work discipline and work facilities had an impact on employee effectiveness. Hypothesis testing using analysis with multiple linear regression results shows that the F value of 39.272 is greater than the F value of 3.15, with a significance level of 0.00 which is smaller than 0.05. This shows that the variables work discipline (X1) and work facilities (X2) have an effect on work productivity (Y), and the alternative hypothesis (H1) is accepted. Furthermore, the regression coefficient for variable X1 was obtained at 0.088 with a significance level of 0.019 (smaller than 0.05). Meanwhile, variable X2 has a regression coefficient of 0.654 with a significance level of 0.00 (smaller than 0.05). This indicates that an increase of one in work discipline may increase the effectiveness of employee performance by 0.088, while every increase of one in work facilities will increase the effectiveness of employee performance by 0.654. Multiple linear regression analysis shows that the influence of work discipline (X1) and work facilities (X2) on employee performance effectiveness (Y) is 55.7%.
