The plantation sector is one of the main pillars in Indonesia’s international trade. Commodities such as palm oil, rubber, coffee, and cocoa serve as leading export products that contribute significantly to the country’s foreign exchange earnings. This study aims to analyze the role of plantation commodity exports in Indonesia’s international economic performance and to identify the challenges faced. The method used is a descriptive qualitative approach through literature review from various scientific sources. The results indicate that plantation exports contribute substantially to economic growth, employment generation, and the stability of the trade balance. However, several challenges persist, including global price fluctuations, sustainability issues, and international trade barriers. Therefore, strategic policies are required to enhance the competitiveness of Indonesia’s plantation commodities in the global market.

This study is motivated by the importance of economic growth as a key indicator of regional development performance and public welfare improvement. Economic growth reflects the ability of local governments to manage resources and implement effective fiscal policies. This research aims to analyze the development and the influence of Local Own-Source Revenue, General Allocation Fund, and Special Allocation Fund on the economic growth of regencies/cities in Jambi Province during the period 2020–2024. The study employs a quantitative approach combined with descriptive analysis. Secondary data are obtained from official publications of relevant institutions and analyzed using panel data regression with the Common Effect Model approach. The results indicate that Local Own-Source Revenue and the General Allocation Fund have a significant effect on economic growth, showing that the increase in regional revenue and fiscal transfers contributes to economic performance. Meanwhile, the Special Allocation Fund does not have a significant effect, indicating that its allocation may not be optimally utilized in stimulating regional economic activities. These findings imply that strengthening regional fiscal capacity and improving the effectiveness of fund allocation are essential to promote sustainable economic growth. The study also highlights the need for better policy coordination and efficient financial management at the regional level to reduce disparities and enhance development outcomes.  

Hydrogen-based hybrid microgrid systems have emerged as a promising solution to enhance renewable energy integration and improve energy supply reliability. By combining renewable sources such as solar and wind with hydrogen production and storage technologies, these systems address the intermittency of renewable power while ensuring continuous energy availability. This study evaluates the techno-economic feasibility, environmental impact, and scalability of hydrogen-based hybrid microgrids, with a focus on cost-effectiveness and system performance under varying operating conditions. Simulation tools, including HOMER Pro and MATLAB Simulink, are used to model the system and conduct sensitivity analyses on hydrogen production costs and demand fluctuations. Key performance indicators such as Levelized Cost of Energy (LCOE), Net Present Value (NPV), and CO₂ emissions reduction are assessed. The results show that although the system requires a high initial investment, it becomes economically viable over time due to reduced operational costs and improved efficiency. Additionally, the system demonstrates significant environmental benefits, outperforming conventional fossil fuel-based systems in terms of emissions reduction. Sensitivity analysis further indicates that advancements in hydrogen production technologies could substantially enhance economic feasibility. Overall, hydrogen-based hybrid microgrids offer a reliable and low-carbon energy solution, supporting sustainable energy transitions and reducing dependence on fossil fuels.

This study aims to analyze the contribution and potential of the Lampung Province tourism sector to national economic growth in the 2020-2025 period. Using a quantitative descriptive approach using the Location Quotient (LQ) and Shift Share methods, this study processes secondary data on Gross Regional Domestic Product (GRDP) at constant prices from the Central Statistics Agency. The analysis shows that although Lampung's macroeconomic performance is still dominated by the primary sector, the tourism sector, particularly the accommodation and food and beverage subsector, has demonstrated post-pandemic resilience with a significant positive growth trend. In 2024, the GRDP value of this subsector at the provincial level reached IDR 4,616.76 billion, with strategic areas such as Bandar Lampung City confirming the accommodation sector as a base sector (LQ > 1) with a high competitive advantage. The integration of a creative economy based on local wisdom, such as the use of Tapis cloth and digital marketing, has been proven to increase the attractiveness of destinations, capable of driving the volume of domestic tourist trips to reach 17.87 million trips by 2024. This finding confirms that Lampung's tourism sector is not only a regional economic driver, but also makes a substantial contribution to national income through a multiplier effect on job creation and increasing domestic foreign exchange. Optimizing collaboration between policymakers and accelerating infrastructure development are key to strengthening the strategic position of Lampung tourism in the future.

Low financial literacy, weak sharia-based governance, and limited business legality remain key barriers to the sustainability of Micro, Small, and Medium Enterprises (MSMEs). These constraints reduce managerial capability, restrict access to formal financing, and hinder business growth. This study developed an integrated mentoring model combining financial literacy, sharia governance, and business legalization using a Participatory Action Research (PAR) approach. 25 MSMEs in Brebes Regency participated in four stages: needs assessment, training, mentoring, and evaluation. Data were collected through pre- and post-tests, bookkeeping observations, and legality checklists. Results showed significant improvements: financial literacy scores increased from 52 to 84 (61.5%), bookkeeping adoption rose from 20% to 88%, and Business Identification Number (NIB) ownership increased from 32% to 84%. Average monthly turnover also grew by 33%. These findings indicate that participatory and practice-based mentoring effectively enhances knowledge, behavior, and economic performance. The model offers a scalable strategy for strengthening sustainable and ethical MSME management.

Tobacco is a leading commodity that forms the foundation of the rural economy, but its cultivation faces challenges in the form of labour intensity, significant capital requirements, and farmers' lack of understanding of systematic cost structures. This study aims to analyse the production cost structure and evaluate the economic efficiency of tobacco farming managed by the Batu Daun Farmer Group in Batuan Village, Sumenep Regency. The research method used a qualitative descriptive approach with data collection through in-depth interviews with the head of the farmer group, field observations, and analysis of financial documents as secondary data. The analysis focused on identifying fixed and variable costs, as well as evaluating economic performance using the Break Even Point (BEP) and Revenue-Cost Ratio (R/C) indicators. The results showed that the total production cost was IDR 28,597,500 (fixed costs of IDR 3,450,000 and variable costs of IDR 25,147,500) for the production of 2,800 kg of tobacco with a gross income of IDR 70,000,000. The R/C ratio value of 2.44 (>1) indicates that the business is operating efficiently and profitably, while the BEP of 215.4 kg shows that actual production far exceeds the break-even point, meaning that the business is in an economically safe zone. The results of the study conclude that the tobacco farming business of the Batu Daun Farmer Group is economically viable and efficient.

Koperatives are a form of people-based economic organization that play a strategic role in improving community welfare and strengthening the national economy. However, many cooperatives still face organizational and managerial challenges that limit their economic performance. This study aims to analyze the relationship between cooperative organizational structures, governance mechanisms, and the economic performance of cooperatives in the context of modern economic transformation. A qualitative descriptive approach was employed to gain an in-depth understanding of organizational practices within cooperatives. Data were collected through in-depth interviews, participatory observation, and document analysis involving cooperative managers, members, and supervisors selected purposively. The findings indicate that cooperatives with clear organizational structures, professional management, transparent governance, and active member participation tend to demonstrate better economic performance and sustainability. Conversely, weak organizational arrangements and low member involvement are associated with stagnation in cooperative economic activities. These results highlight that organizational quality is a key determinant of cooperative success, not merely financial factors. The study implies that strengthening cooperative governance, improving human resource capacity, and enhancing member participation are essential strategies to increase the competitiveness of cooperatives in the digital economy era. This research contributes to the development of cooperative economic theory and provides practical recommendations for cooperative managers and policymakers.
