Estimation of Understorey Carbon Stocks in Post-Mining Land: A Case Study of One-Year Revegetation at PT Insani Baraperkasa Site Loa Janan, East Kalimantan
No full textPost-mining land rehabilitation is an important strategy to mitigate climate change and conserve tropical ecosystems. Surface mining activities in East Kalimantan have caused ecological degradation and the release of carbon stored in vegetation and soils. Revegetation has been widely practiced as the main approach to restore ecosystem functions, including initial carbon accumulation by understory plants. This study aims to estimate the carbon stock of the understory on post-mining land that has undergone revegetation for one year at the PT Insani Baraperkasa site in Loa Janan, East Kalimantan. The method used was destructive sampling of understory biomass from 10 plots measuring 5 m x 5 m, each with subplots measuring 0.5 m x 0.5 m. Biomass samples were dried and converted to carbon. The results showed an average carbon stock of 1.26 tons/ha. These results suggest that understorey vegetation plays an important role in early stage carbon recovery on post-mining land. Understory carbon monitoring can be an effective early indicator to measure the success of ecosystem restoration.

The Phytoremediation effect on the pH and TSS of acid mine drainage by constructed wetland metods
Full text linkCoal mining is a significant contributor to the economy of East Kalimantan Province, with most activities employing open-pit mining systems involving stripping and transporting soil surface. If not properly managed, these activities can lead to Acid Mine Drainage (AMD), which is rainwater and groundwater reacting with sulfide content. Without any treatment before discharge into the environment, AMD can cause environmental pollution. One such treatment method is constructed wetlands, utilizing Pontederia crassipes to absorb heavy metals present in AMD. This study aims to determine the phytoremediation effect on the pH and TSS of acid mine drainage using constructed wetland methods. The research was conducted at PT. Lanna Harita Indonesia, using three 60x50x50 cm container boxes as a collection pond for AMD, a phytoremediation pond containing sand, zeolite rock, and filter cotton, and a constructed wetland phytoremediation pond containing Pontederia crassipes. The results show that Pontederia crassipes can increase the acidic pH from 4.11 to 7.65 and reduce the TSS value from 1016 mg/L to 22 mg/L. This indicates that the final AMD values after phytoremediation treatment comply with the quality standards outlined in East Kalimantan Regional Regulation No. 2 of 2011, meaning it is suitable for discharge into the environment with minimal negative environmental impact

Full text linkIn response to the growing need for effective governance and public service delivery, this study investigates the implementation of the E-Kinerja system at Bukit Biru Village, Tenggarong District, Kutai Kartanegara Regency. The system was introduced as part of the Regulation of the Minister for Administrative and Bureaucratic Reform of the Republic of Indonesia No. 6/2022, which mandates the use of electronic performance management systems within government institutions. The purpose of this regulation is to improve the efficiency, transparency, and accountability of public servants, thereby enhancing the quality of public services. The E-Kinerja system, designed to manage, monitor, and evaluate employee performance more effectively, is expected to streamline public service delivery and align it with organizational goals. This research employs a qualitative descriptive approach to explore the implementation process and its impact on public service quality in the Bukit Biru Village government office. The study includes interviews with government officials, staff observations, and document analysis of the E-Kinerja system's application. The findings suggest that while the system has shown potential in improving the tracking and evaluation of employee performance, its implementation has faced several challenges. These challenges include limited training opportunities, a lack of thorough understanding among employees regarding the benefits and features of the system, and inconsistent participation in using the E-Kinerja platform. Furthermore, the study reveals that some critical factors support the implementation process, including the leadership's commitment to adopting new technologies, the integration of the system with existing human resource management practices, and the alignment of the system’s objectives with the goals of the public sector. However, despite these positives, the study identifies several barriers that undermine the effectiveness of the system, such as insufficient communication regarding the importance of employee engagement, the complexity of the platform, and technical limitations such as inconsistent internet access. This study highlights the importance of providing continuous training and ensuring that all employees understand the advantages of using the E-Kinerja system for both their individual development and the overall improvement of public services. Additionally, a robust communication strategy is crucial to ensuring employee buy-in and effective implementation. The research concludes by suggesting several policy recommendations aimed at optimizing the E-Kinerja system, such as enhancing staff involvement in the decision-making process, improving access to resources, and reinforcing the commitment to public service quality through better managerial support. This paper contributes to the growing body of literature on public administration and electronic government systems, offering valuable insights into the implementation challenges and opportunities that come with digitizing government performance management. It also provides a case study for other governmental bodies in Indonesia and beyond that aim to implement similar E-Kinerja systems to strengthen public sector governance and improve service delivery
Implementation of Special Village Financial Assistance Policy to Realizing Village Self Reliance in Rapak Lambur Village
Full text linkThe village plays a central role in Indonesia's decentralized governance and serves as a strategic unit for achieving equitable and sustainable development. In this context, the Special Village Financial Assistance (BKKD/K) policy was introduced as a mechanism to enhance financial capacity, promote local autonomy, and stimulate grassroots development initiatives. This study explores the implementation of the BKKD/K policy in Rapak Lambur Village, Tenggarong District, Kutai Kartanegara Regency, with the objective of assessing its effectiveness in fostering village self-reliance. Using a qualitative case study approach, data were collected through in-depth interviews, participatory observation, and analysis of official documents. The research highlights that BKKD/K has contributed significantly to infrastructure improvements, economic empowerment programs, and increased village-generated income. However, the implementation process faces several persistent challenges, including limited financial management capacity among village officials, inadequate community participation in planning and monitoring, and weak accountability mechanisms. Findings suggest that while the BKKD/K policy has the potential to reduce dependency on central government transfers, its success depends largely on good governance practices such as transparency, accountability, and participatory decision-making. Moreover, enhancing the managerial skills of village apparatus and promoting civic engagement are critical to ensuring sustainable outcomes. The study underlines the importance of adaptive policy support and technical assistance to overcome institutional constraints and to align village development priorities with community needs. Ultimately, the implementation of BKKD/K in Rapak Lambur demonstrates both the promise and the limitations of fiscal decentralization at the village level, offering practical insights for policymakers and practitioners aiming to strengthen village autonomy and resilience across Indonesia
Implementation of the Electronic Performance System for State Civil Apparatus at the Tenggarong Seberang Sub-District Office
Full text linkThis study explores the implementation of the Electronic Performance System for State Civil Apparatus at the Tenggarong Seberang Sub-District Office, Kutai Kartanegara Regency. The system was developed as part of the Indonesian government's broader strategy to improve bureaucratic performance and accountability through the application of digital governance (e-government). The research applies to a qualitative descriptive method with data collected through field observations, in-depth interviews, document analysis, and literature review. Key aspects examined include communication, resource availability, disposition or willingness of implementers, and bureaucratic structure drawing from the policy implementation model of George C. Edwards III. The findings reveal that while the transmission and clarity of the E-Kinerja policy are adequately established through training and socialization activities, the consistency of its application varies among staff. A significant challenge lies in the limited understanding and technical capacity of certain employees to operate the system effectively. In addition, the absence of specific financial resources to support the digital infrastructure and recurring system errors further hinder smooth implementation. However, a strong disposition among the staff and legal support from national regulations such as BKN Regulation No. 7/2023 act as positive factors reinforcing the system’s use. This research concludes that the successful implementation of E-Kinerja depends not only on the system's technical robustness but also on human resource readiness, leadership commitment, and the integration of organizational routines. The case of the Tenggarong Seberang Sub-District Office illustrates both the opportunities and constraints that local governments face in translating central government digital policy into effective administrative practice. The study offers insights for future improvements in performance-based management systems within Indonesia’s public sector
The Relationship Between Height and Diameter of Palaquium Obtusifolium Burck Trees at 7 Years of Age
Full text linkThe relationship between tree height and diameter is a key indicator for understanding growth patterns and the physiological balance of forest trees. In tropical agroforestry systems, this relationship is commonly used to estimate tree height, volume, and biomass without direct field measurements. This study was conducted on a seven-year-old Palaquium obtusifolium (Nantu) stand in Pandiri Village, Poso District, Central Sulawesi Province, to identify the pattern of the relationship between stem diameter and total height. Measurements were taken from 64 trees, which were measured with a Suunto clinometer and a phi tape. Data normality was tested using the Shapiro–Wilk test, and potential outliers were identified through boxplot analysis. The relationship between height and diameter was analyzed using a simple linear regression model in R Studio. The results showed a significant linear relationship between diameter and height, expressed by the equation H = 4,82 + 0,48D, with a coefficient of determination (R²) of 0,69. This indicates that approximately 69% of the variation in tree height could be explained by stem diameter. The regression model was statistically significant (p < 0,05) and could be effectively applied to estimate tree height in the field.

Predicting Loan Delinquency in Installment Loans Using LightGBM for Enhanced Credit Risk Management
Full text linkCredit risk assessment is essential for financial institutions to effectively manage loan portfolios, especially for installment loans. Predicting delinquency is challenging due to the complex interplay of borrower behavior, loan characteristics, and repayment pattern. Traditional models often fail to capture non-linear relationships in data and require significant preprocessing to address imbalanced datasets, feature scaling, and diverse data distributions, resulting in inefficiencies. This research predicts installment loan delinquency using LightGBM, a gradient-boosting algorithm tailored for complex, imbalanced financial datasets. Unlike previous studies focusing on general credit risk or credit card defaults, this work specifically addresses the temporal and behavioral dynamics of installment loans. The model uses a real-world dataset from financial institutions, integrating borrower demographics, loan attributes, and engineered repayment features. LightGBM's histogram-based binning and inherent handling of heterogeneous feature scales both reduce preprocessing complexity and improve performance. Evaluation results show significant improvements over traditional models, achieving an AUC-ROC of 0.91 and strong precision and recall. This approach demonstrates scalability and effectiveness for modern credit risk management. Future work could incorporate macroeconomic factors and assess real-time deployment to further expand the model’s applicability
