Open-pit mining activities in Indonesia contribute significantly to the national economy but require stringent monitoring to mitigate environmental degradation. Conventional monitoring methods relying on terrestrial surveys are often constrained by vast coverage areas, high operational costs, and limited field accessibility. This study aims to develop an artificial intelligence model capable of automatically detecting and mapping mining areas to enhance surveillance efficiency. The applied method is Deep Semantic Segmentation utilizing the U-Net Convolutional Neural Network (CNN) architecture. The model was trained using Sentinel-2 satellite imagery, focusing exclusively on Red, Green, and Blue (RGB) spectral channels to replicate human visual perception. Experimental results demonstrate that the proposed model performs reliable segmentation of mining areas, achieving an Accuracy of 93.58% and a Global Intersection over Union (IoU) of 0.8067. These findings indicate that the U-Net architecture can effectively extract spatial features of mines even when utilizing standard visual data. This research contributes to the development of an efficient, cost-effective, and scalable digital monitoring prototype to support innovation in sustainable environmental governance.

This article examines how meritocracy is institutionalized within the public administration systems of Indonesia and Singapore and how it affects public service quality. Using a descriptive–comparative library research design, the analysis focuses on four dimensions: bureaucratic structure, governing system and political influence, administrative reform and merit mechanisms, and implications for service delivery. The findings indicate that Indonesia’s bureaucracy remains highly hierarchical and decentralized, creating uneven institutional capacity and allowing electoral–political dynamics to influence appointments and rotations, which weakens consistent merit implementation. In contrast, Singapore operates a streamlined and centrally coordinated bureaucracy supported by high political stability, rigorous competency-based recruitment and promotion, transparent performance management, and competitive remuneration, enabling merit principles to be applied more consistently. These differences translate into more uniform and efficient public services in Singapore, while Indonesia continues to experience variability across regions and sectors. Strengthening merit enforcement, oversight, and professional culture is therefore crucial to improve the effectiveness and equity of public services in Indonesia.

State revenue holds a vital position in sustaining national development and the functioning of government, with taxation serving as the primary contributor to Indonesia’s State Budget (APBN). The substantial reliance on tax income obliges the government to manage the taxation system in an optimal, efficient, and sustainable manner. Nevertheless, the attainment of tax revenue targets in practice remains challenged by various issues, including structural, administrative, and strategic limitations. This study seeks to examine the role of strategic tax management in supporting the achievement of state revenue objectives. The research adopts a literature review approach by analyzing textbooks, national and international scholarly journals, official government publications, and relevant regulatory frameworks. The data are analyzed using a descriptive qualitative method through processes of classification, comparison, and synthesis of findings from previous studies. The findings reveal that strategic tax management has a crucial influence on enhancing state revenue performance through coherent policy formulation, flexible strategy execution, and ongoing performance assessment. The integration of information technology, the reinforcement of tax administration, and the improvement of taxpayer compliance emerge as key determinants in achieving revenue targets. Accordingly, strategic tax management constitutes a fundamental tool for ensuring fiscal resilience and promoting sustainable national development.

Breach of contract disputes with small claim values are often hindered by the lengthy and costly conventional litigation process. To address this issue, the Supreme Court issued PERMA No. 2 of 2015, which was later amended by PERMA No. 4 of 2019 concerning Small Claims Court. This study aims to examine the mechanism for resolving breach of contract disputes through small claims and its effectiveness in achieving the principles of fast, simple, and low-cost litigation. This research uses a normative legal method to analyze the relevant legal procedures and regulations. The findings show that small claims court is effective in streamlining the litigation process, with a resolution time limit of a maximum of 25 working days, much faster compared to regular litigation, which can take much longer. However, the implementation of this mechanism is limited by the requirement that evidence must be simple, which can be a challenge in some cases. Thus, small claims court can be an efficient and affordable solution for business disputes with low claim values.

Regional government financial performance is a strategic indicator for assessing the success of regional autonomy implementation, particularly in managing public finances in an effective, efficient, transparent, and accountable manner. This study aims to analyze the financial performance of the Government of West Nusa Tenggara Province (NTB) during the 2018–2022 period using a regional financial ratio analysis approach. The research employs a descriptive quantitative method utilizing secondary data obtained from the Budget Realization Reports (LRA) and the Regional Government Financial Statements (LKPD) that have been audited by the Audit Board of the Republic of Indonesia (BPK). The analysis is conducted by calculating regional financial ratios, including the financial independence ratio, the effectiveness ratio of Regional Original Revenue (PAD), the efficiency ratio of regional finances, the activity ratio (expenditure harmony), and the revenue growth ratio. The results indicate that the financial performance of the Government of West Nusa Tenggara Province has generally improved. The regional financial independence ratio falls within the participatory category with an average value of 57.81%, reflecting a gradual reduction in dependence on central government transfer revenues, particularly in 2022. The effectiveness ratio of PAD is categorized as moderately effective, with an average of 92.84%, although it fluctuates due to increases in revenue targets that were not fully matched by actual revenue realization. The regional financial efficiency ratio consistently remains in the efficient category, indicating the local government’s ability to control expenditures relative to revenues. Furthermore, the activity ratio analysis shows a shift in expenditure composition from operating expenditure toward capital expenditure, indicating an increased orientation toward development and long-term investment. The growth ratio reveals a significant increase in PAD in 2022, accompanied by a decline in transfer revenue growth.

This study aims to analyze the financial performance of the East Java Provincial Government based on the Budget Realization Report (LRA) for the 2022–2024 period. This study is important to assess the effectiveness of revenue achievement and the efficiency of regional expenditure management. The research method used is quantitative descriptive with secondary data in the form of Budget Realization Reports obtained through documentation techniques. Data analysis was performed using financial ratio analysis, namely effectiveness and efficiency ratios. The results show that the revenue performance of the East Java Provincial Government is in the highly effective category, as reflected in the realization of revenue that was able to reach and even exceed the budget target. However, regional expenditure performance is still considered inefficient because the realization of expenditure is close to the set budget. The conclusion of this study shows that even though revenue optimization has been achieved, the local government still needs to improve expenditure control so that regional financial management becomes more efficient in the future.
