The Free Nutritious Meal Program (MBG) is a strategic initiative by the Indonesian government to address the long-standing issues of malnutrition and stunting, which have significantly hindered human resource (HR) development in Indonesia. The program aims to improve children's nutrition and reduce stunting by providing free nutritious meals, particularly in areas with limited access to healthy food. This study aims to analyze the legal framework of MBG, its effectiveness in achieving its goals, and its impact on national development. Using a qualitative approach, the study analyzes the implementation of MBG through document analysis, interviews with relevant stakeholders, and field observations. The findings highlight challenges within the program, including imbalanced food distribution, inadequate infrastructure in remote areas, and suboptimal food quality control, which resulted in several food poisoning incidents in 2025. Nevertheless, the program has a positive economic impact by empowering micro, small, and medium enterprises (MSMEs) involved in food supply. The study suggests strengthening the monitoring system, improving budget management, and better coordination between government sectors and communities to maximize the success of MBG. It also emphasizes the importance of nutrition education campaigns to support the program's goals. Overall, MBG is a crucial step toward creating a healthier and more productive generation, supporting the achievement of Indonesia's Golden Generation by 2045..

This study examines the role of the Lubuk Intan Village Unit Cooperative (KUD) in assisting in managing oil palm sales for smallholder farmers in Peninjau Village, Batanghari Regency. The background of this study is based on the suboptimal distribution of economic benefits to farmers, despite increasing sales through the cooperative. This situation indicates the need to strengthen the role of cooperatives in the harvest marketing system. This study used a qualitative approach with descriptive methods. Thirteen informants were interviewed: three administrators and ten members of the Lubuk Intan KUD in Peninjau Village, Batanghari Regency. The results indicate that the Lubuk Intan KUD plays a role in facilitating collective sales, providing price information, and creating certainty and transparency in the weighing and recording of harvests. This role has been able to improve marketing efficiency and member trust. However, its implementation still faces obstacles such as limited human resources, limited operational capital, and inadequate member participation.

Fish farming using the biofloc system is a technological innovation capable of increasing efficiency, production results, and the sustainability of fisheries business at the village level. This study aims to determine the development of fish farming businesses using the biofloc system in increasing family income in Sembuluh village. Then, it aims to understand the impact of using the biofloc system in increasing family income and to understand the Islamic economic perspective on the utilization of the biofloc system in increasing family income. The method used is a qualitative or field research approach with purposive sampling techniques to collect data from 5 fish farmers who implement the biofloc system. Data were collected through in-depth interviews, observation, and documentation, then analyzed descriptively. The research results show that fish farming using a biofloc system is able to increase family income through increased production and feed cost efficiency. This system supports more controlled pond management, maintains water quality, and produces more stable harvests. In addition to increasing income, the implementation of the biofloc system also strengthens family economic resilience due to planned harvest cycles and group cooperation. From an Islamic economic perspective, this practice aligns with the principles of halal, honesty, justice, and social responsibility, as well as providing benefits for families and the community.

This study aims to analyze the impact of the geopolitical conflict between the United States, Israel, and Iran in 2026 on global macroeconomic stability and climate change dynamics. Using a qualitative approach through a Systematic Literature Review (SLR), this research synthesizes findings from various international journal articles, reports, and academic sources. The results indicate that the conflict has significantly disrupted global energy markets, leading to a sharp increase in oil and gas prices. This energy shock has triggered global inflationary pressures, reduced purchasing power, and increased economic uncertainty across both developed and developing countries. Furthermore, monetary tightening policies implemented to control inflation have created trade-offs with economic growth, increasing the risk of global recession. On the fiscal side, government interventions such as energy subsidies have helped mitigate short-term impacts but have raised concerns about long-term fiscal sustainability. In addition, the energy crisis has slowed the transition toward renewable energy, thereby exacerbating climate change risks. The study highlights the interconnectedness between geopolitical conflict, macroeconomic instability, and environmental sustainability. Therefore, coordinated global policies and integrated economic strategies are essential to address these multidimensional challenges effectively.

Micro, Small, and Medium Enterprises (MSMEs) are one of the key pillars of the rural economy, including in Karangkuten Village. Although they exist in significant numbers and possess considerable economic potential, most rural MSMEs still face various limitations in the marketing aspect, particularly in utilizing rapidly developing digital media. This Community Service Program (KKN) of the Faculty of Economics aims to support the digitalization process of MSMEs through the creation of engaging promotional videos integrated with the official website of Karangkuten Village. The implementation method of this program includes stages of socialization for MSME actors, video recording in six hamlets, a systematic editing process, as well as uploading and handing over the results to the village government. The results of the activity indicate that this program successfully produced MSME promotional video content that is not only engaging and informative but also suitable for publication on the village website as a digital promotional medium. In addition to increasing the visibility and branding of MSMEs, this program also contributes to strengthening the image of Karangkuten Village as a culinary village and a center for innovative creative MSMEs. This program is expected to provide long-term impacts in improving the competitiveness of MSMEs and encouraging sustainable and inclusive rural economic growth.

This study aims to analyze the optimization of regional expenditure in the education sector of Surabaya City for the 2025 fiscal year in supporting regional development. The research uses a descriptive qualitative approach through observation, interviews, and documentation studies conducted at the Surabaya City Education Office. Data were obtained from relevant stakeholders involved in education budget management and supported by official documents related to policies and the implementation of education programs. The results show that the management of education expenditure has been aligned with the Regional Medium-Term Development Plan (RPJMD) and applies the money follow program principle, which prioritizes programs based on community needs and development priorities. Programs such as Regional School Operational Assistance (BOPDA), educational assistance for students, school infrastructure development, and community-based learning innovations have contributed to expanding access to education, improving the equity of educational services, and reducing dropout rates. In addition, the use of monitoring systems, periodic evaluation, and the involvement of multiple stakeholders in supervision has strengthened transparency and accountability in budget management. However, several challenges remain, including limited implementation time, procurement constraints, and economic conditions such as inflation. Overall, education expenditure in Surabaya has been managed relatively well in terms of effectiveness, efficiency, and accountability while still requiring continuous improvement

This study examines the legal implications of the regulation of foreign investment (FDI) and domestic investment within the Indonesian legal system, as well as its relation to national economic sovereignty. The background of this research is rooted in the need of developing countries, including Indonesia, to attract investment in order to promote economic growth while still safeguarding national interests as mandated by the constitution. This research employs a normative juridical method with statutory and conceptual approaches. The results show that although foreign and domestic investments are regulated under a single legal framework through Law Number 25 of 2007, there are significant differences in terms of legal subjects, business entities, as well as ownership and sectoral restrictions. These differences do not constitute discrimination, but rather reflect the state’s protective legal policy. On the other hand, foreign investment brings positive impacts such as capital inflow, technology transfer, and market expansion. However, it also poses potential risks, including economic dependency and reduced policy autonomy. Therefore, a balance between investment openness and regulatory control is necessary to ensure that economic sovereignty is maintained and the benefits of investment can be optimally realized for society.

High dependence on the United States Dollar (USD) in international transactions has long been a challenge for economic stability in the Southeast Asian region, especially amidst global exchange rate fluctuations and geopolitical tensions. This study aims to analyze the effectiveness of Local Currency Settlement (LCS) cooperation in supporting intra-ASEAN trade stability. The main focus of this study is how local currency mechanisms can mitigate exchange rate risks and strengthen regional economic integration as part of a de-dollarization strategy. The research method used is descriptive qualitative with a literature review approach, relying on secondary data from central bank reports, ASEAN policy documents, and relevant academic literature. The results show that the implementation of the LCS framework, particularly in countries such as Indonesia, Malaysia, and Thailand, has provided more efficient transaction alternatives by reducing double conversion costs. However, its effectiveness still faces challenges such as low awareness among business actors, limited local currency liquidity compared to the USD, and the need for broader cross-border digital payment system integration. These findings imply the need for strengthened synergy between central banks in the ASEAN region and increased literacy for the private sector so that the economic stability benefits of LCS can be optimally achieved. This strategy not only strengthens monetary sovereignty but also encourages a more resilient ASEAN economic integration against external shocks.

The retention of customers in the retail banking sector is a critical economic imperative; however, predictive modeling is frequently hindered by severe class imbalance and the “Black Box” nature of complex algorithms. This study proposes a Heterogeneous Stacking Ensemble framework integrating XGBoost, CatBoost, and Random Forest base learners with a Logistic Regression meta-learner to forecast customer attrition. To overcome the pervasive “Majority Class Bias,” we introduce a “Dual-Imbalance Defense” that synergizes the Synthetic Minority Over-sampling Technique (SMOTE) with algorithmic cost-sensitive penalization. Furthermore, moving beyond standard accuracy metrics, the framework mathematically derives a dynamic classification threshold to guarantee a strict 0.90 recall rate, actively optimizing the capture of at-risk capital. Model opacity is addressed through the integration of a SHapley Additive exPlanations (SHAP) TreeExplainer. This cooperative game theory approach provides localized, patient-level “Reason Codes” for regulatory compliance and reveals global systemic vulnerabilities, including non-linear drivers such as the “Product Paradox.” Achieving a 0.90 recall rate and an AUC of 0.8654, this framework provides a statistically robust and operationally transparent tool for targeted customer retention.

This study examines the implementation of Indonesia’s Visa on Arrival (VoA) policy in DKI Jakarta as both an instrument of tourism-driven economic recovery and a component of non-military national defense management under Law No. 23 of 2019 on the Management of National Resources for National Defense. While VoA has significantly contributed to the rebound of international tourist arrivals—surpassing 11 million visits nationally in 2023—it simultaneously generates governance challenges at strategic entry points such as Soekarno–Hatta International Airport, where facilitation of mobility intersects with risks including overstaying, transnational crime, human trafficking, and potential infiltration by non-state actors. Existing scholarship largely emphasizes economic impacts and regulatory frameworks, leaving limited analysis of VoA as part of an integrated civil defense infrastructure. Addressing this gap, the study aims to analyze how VoA implementation in DKI Jakarta is managed within a non-military defense perspective, particularly regarding institutional coordination, immigration intelligence, and risk mitigation mechanisms. Employing a qualitative case study approach, data were collected through in-depth interviews with immigration officials and security stakeholders, document analysis of relevant laws and ministerial regulations, and review of official immigration statistics, followed by thematic analysis. The findings indicate that although VoA effectively supports economic and diplomatic objectives, its function as a non-military defense instrument remains constrained by fragmented inter-agency coordination, uneven intelligence integration, and limited adaptive governance capacity at the local level. Strengthening collaborative surveillance systems, data-sharing mechanisms, and strategic policy alignment between immigration authorities and national defense institutions is therefore essential. The study concludes that reframing immigration governance as part of Indonesia’s broader non-military defense strategy is crucial to balancing openness with security in high-density international gateways.

Attention mechanisms have been widely incorporated into recurrent neural network architectures for financial time series forecasting, with most prior work reporting improvements in price-level error metrics. This study revisits that claim through a controlled empirical comparison of four deep learning architectures on nearly two decades of Telkom Indonesia (TLKM) closing price data from the Indonesia Stock Exchange (IDX). The models evaluated are a three-layer Gated Recurrent Unit (GRU) baseline, a comparable Long Short-Term Memory (LSTM) network, a Bahdanau end-attention GRU (Attn-GRU-V2), and a multi-head self-attention GRU hybrid (Attn-GRU-V3). Each architecture is trained over 30 independent runs with distinct random seeds, and performance is reported as 95% confidence intervals derived from the t-distribution. Statistical comparisons employ the Wilcoxon signed-rank test, a nonparametric paired test appropriate given the confirmed non-normality of residuals. The main finding is a consistent trade-off: the plain GRU achieves the lowest RMSE (94.02 ± 1.22 IDR) across all 30 runs, while Attn-GRU-V2 achieves the highest directional accuracy (45.91 ± 0.09%), surpassing GRU in every independent run. Bahdanau attention weights are nearly uniform across the 30-day lookback window (coefficient of variation: 3.21%), indicating that the mechanism cannot identify selectively informative timesteps in this univariate price series. This finding is consistent with the weak-form Efficient Market Hypothesis for the Indonesian market. An ablation study reveals that a 20-day lookback window maximizes directional accuracy (47.72 ± 0.21%) for the Attn-GRU-V2 model. These results suggest that Bahdanau end-attention consistently and significantly improves directional accuracy relative to a plain GRU baseline, providing an architecturally attributable advantage for direction-based applications, even when absolute price-level error is not reduced. The directional accuracy values remaining below 50% across all models are consistent with a weak-form efficiency characterization of the Indonesian market.

The money market plays a vital role in the global financial architecture as a provider of short-term liquidity and a primary channel for monetary policy transmission. This research is motivated by the rapid transformation of financial instruments, which now encompass conventional and Sharia-compliant sectors, as well as digital innovations such as e-money and stablecoins. The purpose of this study is to examine the concept of the money market, identify the diversity of modern instruments, and analyze their strategic role in economic stability through a qualitative literature review approach. The analysis shows that the money market is highly effective in managing bank cash reserves and controlling inflation by regulating the money supply. The presence of digital instruments has been proven to accelerate liquidity flows, while Sharia schemes provide transparent and equitable investment alternatives. However, the emergence of digital assets also brings challenges of volatility that require adaptive regulation and professional skepticism from market participants. The implications of this research emphasize the importance of synergy between monetary authorities and financial technology to address global disruption. Strengthening regulations on future instruments is expected to create a more inclusive and stable financial system that can respond precisely to economic shocks.

Micro, Small, and Medium Enterprises (MSMEs) and Village-Owned Enterprises (BUMNeg) in Makariki possess regional economic potential. However, business managers face cash flow recording obstacles. They have not implemented standard bookkeeping. This community service aims to provide training and mentoring in financial document preparation using the Financial Accounting Standards for Micro, Small, and Medium Entities framework. The implementation method consists of preparation, execution, and evaluation stages. The execution stage includes initial testing, material presentation, interactive discussion, and final testing. Evaluation results indicate this program resolves participants' financial literacy problems. Participants' understanding regarding bookkeeping accounts and calculating profit and loss increased. Participants can compile drafts of income statements, financial positions, and supporting notes independently. In conclusion, intensive mentoring changes participants' mindsets from conventional management to a more structured one. Systematic bookkeeping helps participants separate personal and business assets. These records also serve as administrative requirements to access additional capital from banks or government assistance programs. This program supports the transparency and accountability of village fund management through BUMNeg.

This research aims to analyze the urgency of implementing Statement of Use, Declaration of Use, and Specimen of Use instruments as a means of supervising trademark use obligations in Indonesia. Currently, Law Number 20 of 2016 concerning Trademarks and Geographical Indications (UU MIG) only requires a written statement of use without being accompanied by concrete evidence at the time of renewal applications. This creates a loophole for trademark registrations without the intent to use (non-use), which can hinder bona fide applicants.  This study employs a normative legal research method with a comparative law approach between the UU MIG and the Lanham Act (U.S. Trademark Act of 1946). The Lanham Act mandates proof of actual trademark use through a Statement of Use for intent-to-use applications, as well as a Declaration of Use for applications based on use-in-commerce, which must be submitted with a Specimen of Use as actual evidence of the trademark's use in trade.  The results indicate that the adoption of these instruments into the Indonesian legal system is urgent to strengthen the supervisory function of the Directorate General of Intellectual Property (DGIP). This implementation would enable the DGIP to conduct administrative (ex-officio) trademark cancellations for non-use, thereby purging the trademark database of passive marks without having to rely on third-party lawsuits. This legal reform is in line with the legal development theory to encourage business actors to actively utilize the economic functions of trademarks.

Zakat is a key instrument in the Islamic economic system, functioning as a mechanism for income redistribution and poverty alleviation. However, zakat management at the level of mosque-based Zakat Collection Units (Unit Pengumpul Zakat/UPZ) still faces significant challenges, particularly in terms of managerial capacity, administrative systems, and institutional governance. This community service project aims to optimize the collection and distribution of zakat through capacity building of the UPZ management at Al-Hidayah Mosque, Mandailing Natal. The study employed a participatory approach consisting of observation, joint planning, socialization, training, mentoring, and evaluation stages. Data were collected using observation, interviews, and structured questionnaires administered through pre-test and post-test to measure participants’ knowledge improvement. Data analysis was conducted using a descriptive comparative method to assess changes before and after the intervention. The results indicate a significant improvement in the managerial capacity of UPZ administrators, as reflected by an increase in the average score from 55% in the pre-test to 80% in the post-test. In addition, improvements were observed in zakat management practices, including the establishment of simple financial recording systems, the development of a structured database of donors (muzakki) and beneficiaries (mustahik), and enhanced transparency and accountability. Qualitatively, the program also fostered behavioral change among administrators, the emergence of local leadership, and increased public trust in the UPZ. This study concludes that participatory-based socialization, training, and mentoring are effective in strengthening institutional capacity and optimizing zakat management at the grassroots level. The findings highlight the importance of governance and capacity building in enhancing the effectiveness of community-based zakat institutions.

The policy plan to integrate parking fees into the Vehicle Registration Certificate (STNK), scheduled for nationwide implementation in 2027, has generated debate regarding contractual validity and fiscal justice. From the perspective of Islamic Economic Law, the transformation from a conventional pay-per-use retribution system to an annual prepaid system raises issues related to mutual consent (an-taradin) and the certainty of service benefits. This study aims to analyze the 2027 subscription parking policy using the framework of Maslahah Mursalah and the principle of distributive economic justice to assess its legitimacy as an instrument of public welfare. This research uses a normative legal method with conceptual and statutory approaches. Literature data are analyzed qualitatively through deductive reasoning to derive legal conclusions from general principles of Islamic economics in relation to contemporary fiscal policy. The findings indicate that the policy contains elements of Maslahah Mursalah, particularly in improving bureaucratic efficiency and preventing state revenue leakage (sadd adz-dzari'ah). However, from the perspective of distributive justice, the policy may contain elements of dzulm (injustice) if it is not supported by fair tariff segmentation. Without guaranteed service availability for all payers, mandatory annual parking fees risk being categorized as akl al-amwal bi al-bathil (unlawful appropriation of wealth). Therefore, a zoning-based tariff system is recommended to ensure fairness between obligations and benefits.

The study of takhrij al-hadith plays a crucial role in hadith scholarship, involving the tracing of transmission sources and evaluating the authenticity of sanad and matn through systematic analysis. In contemporary studies, differences in scholars’ approaches have led to variations in hadith classification and epistemological orientation. However, comparative research examining methodological criticism, epistemological foundations, and operational procedures of modern takhrij remains limited. This study aims to critically compare the methodologies of Muḥammad Nāṣiruddīn al-Albānī and Muqbil bin Hādī al-Wādiʿī, focusing on their evaluation of sanad and matn. Using a qualitative approach with an integrative literature review, this research analyzes primary works and relevant academic sources. The findings reveal three main epistemological patterns: independent reasoning through cross-narration, methodological caution based on classical authority, and a shared reliance on jarḥ wa taʿdīl. These differences influence hadith classification and reflect varying depths of criticism. The study shows that contemporary hadith criticism forms an epistemological spectrum rather than a strict methodological divide. It also highlights implications for religious practices, including the Megengan tradition in Java, which adapts to socio-economic contexts, and enriches comparative studies in hadith methodology.

This study aims to design and implement an information technology-based economic and tourism potential mapping system in Tema Tana Village. This village faces several problems, including manual data management, limited access to information, and the absence of an integrated system for efficiently presenting village potential data. This study uses a descriptive approach with data collection techniques through observation, interviews, and documentation studies. In developing the system, the Waterfall method is used, consisting of the stages of planning, design, implementation, and testing. The system design was carried out using the Unified Modeling Language (UML) to ensure a clear system structure and flow. The results of the system development indicate that the system is able to present information in the form of interactive digital maps and reports that are easily accessible to users. Testing using the Black Box Testing method shows that all system features function well and are in accordance with predetermined needs. Thus, this system is expected to improve the effectiveness of data management and support better decision-making processes in developing village potential, particularly in the economic and tourism sectors.
