The Indonesian Archipelagic Sea Lane II (ALKI II) constitutes a strategic route stretching from the Sulawesi Sea to the Indian Ocean with trade values reaching USD 1.5 million daily and traversed by more than 36,773 vessels annually. The complexity of maritime security threats in this region has increasingly intensified following the relocation of the capital city to East Kalimantan, thereby demanding an effective decision support system to assist Indonesian Warship Commanders in making operational decisions that are rapid, accurate, and in accordance with applicable legal provisions. This research employs a qualitative approach through in-depth interviews with four maritime expert sources, with data analysis using NVivo 12 software. Analysis results identified maritime operational complexity and the urgent need for a comprehensive decision support system. These findings subsequently served as guidance in designing a Decision Support System (DSS) with a tab-based interface that integrates international legal frameworks such as UNCLOS 1982, Law No. 3/2025 on TNI, and related national regulations to generate structured action recommendations along with their legal foundations. Research findings demonstrate that the developed DSS successfully integrates operational, legal, and situational aspects to support decision-making that is rapid, accurate, and legally compliant. This system has proven to enhance the effectiveness of Indonesian Warship Commanders in addressing the complexity of maritime security (KAMLA) challenges in ALKI II through the provision of legally-based action recommendations from national and international frameworks accessible in realtime during operational situations.  

This study examines Egypt's security dilemma in the Bab el-Mandeb Strait in response to the escalation of Houthi attacks on global maritime trade routes. Since late 2023, Houthi attacks on commercial ships in the Red Sea have disrupted major sea trade lanes, posing a direct strategic threat to Egypt, which relies heavily on Suez Canal revenues as a primary source of national income. This research employs a qualitative approach with a descriptive-analytical method, using secondary data from academic journals, international policy reports, and credible news sources. The analysis is grounded in Security Dilemma theory and the concept of Maritime Security within the framework of International Relations. Findings show that Egypt faces a complex strategic dilemma: on one hand, it must safeguard its economic interests through stable Suez Canal operations; on the other, direct military intervention against the Houthis risks political backlash from Arab public opinion and entanglement in Yemen's civil war. Egypt's response has therefore been calibrated, prioritizing diplomatic channels and multilateral coalition participation over unilateral military action. This research contributes a novelty by specifically mapping Egypt's strategic constraints in the Red Sea as a middle power caught between great power competition and regional non-state actor threats.

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.

Regional economic development requires understanding the structure and performance of economic sectors to create effective policies. PadangiCity, the capital of West SumatraiProvince, plays a strategic role in the regional economy. However, differences in sector contributions and growth indicate structural imbalances that need attention. This studyiaims to identify leading and potential economic sectors in Padang City to support sustainable development planning. The study uses Location Quotient (LQ), iDynamic Location Quotient (DLQ), and the Growth Ratio Model (GRM) to analyze secondary data on GrossiRegional Domestic Product (GRDP) at constant 2010 prices from 2020 to 2024, sourced from the CentraliBureau of Statistics of Padang City and West Sumatra Province. LQ results show that most sectors in Padang City are base sectors, especially business services, transportation and warehousing, ifinancial and insurance services, real estate, and wholesale and retail trade. DLQ analysis indicates that mining and quarrying, trade, transportation and warehousing, iinformation and communication, and health and social services have higher growth prospects than the reference region. GRM results show that trade, information andicommunication, real estate, health services, andiother services are leading sectors with good performance and growth potential. In contrast, agriculture, manufacturing, and construction are still lagging sectors. These findings highlight a structural shift in Padang City’s economy toward service-sector dominance and underline the need for sustainable, inclusive, and adaptive development policies to support long-term economic growth.

This study aims to examine the historical legacy of the Sriwijaya and Majapahit Kingdoms in the context of the development of Southeast Asian civilization through a literature review approach. The study focuses on the contributions of both kingdoms in various aspects, including politics, economy, maritime activities, culture, education, and international diplomacy. Research data were obtained from primary and secondary sources, such as historical manuscripts, inscriptions, archaeological reports, and national and international scholarly publications. The findings indicate that the Sriwijaya Kingdom played a significant role as a major maritime power and an international center of Buddhist education that influenced intellectual networks across Asia. Meanwhile, the Majapahit Kingdom was prominent in developing systems of governance, law, and regional integration of the Nusantara through extensive political and trade networks. Both kingdoms not only shaped the social and cultural structures of their respective periods but also laid an important historical foundation for the formation of identity and regional dynamics in modern Southeast Asia. Therefore, the legacies of Sriwijaya and Majapahit remain highly relevant for understanding historical processes, regional integration, and the long-term development of Southeast Asian civilization.

This study examines the optimization of military defense in North Sulawesi as a supporting pillar for Indonesia’s new import gateway. Positioned strategically on the Pacific rim, North Sulawesi is expected to become a hub for imported goods to support national economic equalization. However, this import route shift also brings security challenges, including military and non-military threats such as smuggling, maritime crimes, and potential infiltration by terrorist groups. This research employs a qualitative descriptive method based on literature study, focusing on the analysis of naval and air defense strategies, modernization of main weapon systems (alutsista), and the enhancement of human resources within the Indonesian National Armed Forces (TNI). The results indicate that strengthening defense infrastructure, including the addition of warships, patrol vessels, and modern fighter aircraft, is urgently needed to maintain regional stability. Furthermore, the application of the smart defense concept, integrating advanced technology with local community empowerment, can sustainably enhance maritime resilience. Investment in the defense sector has been shown to create a conducive climate for international trade, boost investor confidence, and strengthen Indonesia’s economic connectivity with the Asia-Pacific region. This study recommends synergy between the Ministry of Defense, TNI, and the national defense industry to accelerate the modernization and maintenance of alutsista, while ensuring the security of trade routes in North Sulawesi. With these measures, North Sulawesi can function optimally as a strategic import gateway that supports national economic growth and reinforces state defense.

The increasing demand for interactive web applications has encouraged the adoption of server-driven approaches such as Livewire as an alternative to building Single Page Applications (SPAs) without complex client-side JavaScript. However, the performance implications of this approach compared to conventional methods remain insufficiently explored. This study presents an empirical comparison between Laravel Blade with AJAX and Livewire in an academic attendance system scenario. Performance evaluation was conducted using k6 on the same web server, complemented by manual browser-based testing to observe actual communication patterns. The results indicate that Livewire exhibits approximately 2.7× higher average response time and up to 6× greater bandwidth consumption than Laravel Blade, primarily due to its snapshot mechanism and state synchronization process. Conversely, Livewire demonstrates better stability, reflected by lower maximum response times and a 0% error rate. These findings highlight a clear trade-off between resource efficiency and development convenience, where Livewire favors stability and developer productivity, while Laravel Blade provides superior efficiency in terms of latency and bandwidth usage.

Consumer protection is an important pillar in ensuring fairness and balance in the relationship between business actors and consumers, including for foreign nationals who transact in Indonesia. Economic globalization and digital developments are expanding the range of cross-border economic activities that demand the presence of an inclusive legal protection system that is adaptive to modern trade dynamics. This research aims to analyze consumer protection for foreign nationals in Indonesia through juridical and sociological approaches to understand the implementation of legal norms, the effectiveness of dispute resolution mechanisms, and the social realities faced by foreign consumers in practice. The research method used is normative legal research with a legislative approach and a sociological approach through the analysis of the literature, regulations, and empirical findings from various studies related to cross-border consumer protection. The results of the study show that although normatively Law Number 8 of 1999 concerning Consumer Protection guarantees equal rights for all consumers, in practice there are still administrative, cultural, linguistic, and information access obstacles experienced by foreign citizens. These findings affirm the importance of harmonizing consumer protection policies with the principles of global justice, accessibility, and non-discrimination.

The food and beverage industry are generally known for its stability. Nevertheless, this sub-sector underwent fluctuations as a result of the COVID-19 pandemic, one of which was in its firm value. The study investigates how firm value is affected by key organizational characteristics, including financial performance, the scale of the firm, and the rate of sales growth. A firm's value is measured by its PBV (Price to Book Value). The study's measure of financial performance is a combination of Return on Equity (ROE) and the CR, DER, and TATO ratios. This study uses a quantitative approach. The study's population is composed of F&B firms publicly traded on the Indonesia Stock Exchange throughout 2019–2023. A purposive sampling technique was used to select the sample based on predefined requirements, leading to a total of 125 samples from 25 companies. Data were processed using WarpPLS version 8.0 to evaluate the research model through model fit, structural testing, and hypothesis testing. The results show that the model meets the required fit indices and has strong explanatory power. The findings reveal that profitability (ROE) and leverage (DER) have a positive and significant effect on firm value, while liquidity (CR) and sales growth exert a negative and significant effect. On the other hand, activity ratio (TATO) and firm size do not significantly influence firm value.

The financial sector plays an important role in promoting Indonesia's economic recovery. This study was conducted to determine the effect of credit to priority sectors on economic growth on the island of Sumatera. The data analysis technique used is dynamic panel data regression analysis with the system-GMM approach. The results of this study indicate that credit for the agricultural, forestry, and fishery sectors; manufacturing sector; the accommodation and food and drink provision sector can increase economic growth on the island of Sumatera, while the construction sector credit; wholesale and retail trade sector; and the transportation and warehousing sectors have a negative influence on economic growth. This shows that the credit of the banking sector has a positive and negative influence on economic growth on the island of Sumatera. Therefore, banks and the government are expected to increase financial literacy to the community and improve internet facilities, especially in rural areas.

The franchise business model has experienced rapid growth in Indonesia, particularly in the food, beverage, and modern retail sectors, such as Indomaret. The franchise system provides efficient business expansion opportunities for franchisors and franchisees to participate in businesses that already have established operational standards and market reputations. However, behind this development, significant legal challenges have emerged, particularly related to the unequal position between franchisors and franchisees in franchise agreements. This study aims to analyze the forms of legal protection for franchisees by reviewing the principles of fairness, balance, and legal certainty in the implementation of franchise contracts. The approach used is a normative juridical method with a case study of the Indomaret franchise partnership, which is examined through an analysis of related laws and regulations, such as Government Regulation Number 42 of 2007 concerning Franchising and Regulation of the Minister of Trade Number 71 of 2019. The results of the study indicate that there is still asymmetry of power in contract drafting, weak legal literacy of franchisees, and a lack of government oversight of agreement implementation. Therefore, regulatory reform and strengthening of oversight mechanisms are needed to ensure that franchise relationships operate fairly, transparently, and sustainably

Belawan Port is a strategic port in North Sumatra with export-import activities reaching 5,000 tons per year, making it an important terminal in supporting international trade and regional economic growth. This research examines the role of daily work reports in dry bulk cargo unloading operations at PT. Wahana Intradermaga Niaga Belawan as a Stevedoring Company (PBM) responsible for ensuring the smooth process of loading and unloading at the port. The research methodology employs library research approach and direct field observation. The dry bulk cargo unloading process involves the inaportnet system and operates for 24 hours with three work shifts. Activities include four main types of operations: stevedoring (transferring cargo from ship to wharf), cargodoring (transfer from wharf to warehouse), delivery (shipment outside the port), and receiving (acceptance from factory to warehouse). The daily report document is a list of all cargo unloading activities during 24 hours at wharf 112. Daily work reports function as structured documentation of daily activities, conveying work progress updates, supporting performance monitoring, and serving as a reference for operational evaluation. The report's usefulness includes strengthening accountability, reducing misunderstandings, early problem detection, consistency in task implementation, and orderly documentation of unloading activities. Operational preparation involves permit processing according to port regulations, equipment preparation such as hopper, conveyor belt, grab, excavator, wheel loader, and sling ropes. Supporting documents include Bill of Lading, Cargo List, Cargo Manifest, and various operational reports. Obstacles faced include the influence of bad weather, human resource constraints related to workforce professionalism, and land transportation barriers. Related institutions include cargo owners, PBM, shipping agents, port authorities, PT. Pelindo Belawan, and EMKL companies that coordinate to ensure smooth dry bulk cargo unloading operations.

This study aims to analyze the thermal performance of the heating system in a small-scale plastic bolt molding machine using LDPE material, in order to determine process parameters that are efficient while maintaining product quality. The method used includes experimental testing at two set-point temperatures (90 °C and 120 °C), measurement of melting time and feed mass per cycle, as well as heat balance calculations separating the contributions of conduction, convection, and radiation on the barrel heated by a band heater. In addition, the power/energy requirement per cycle and productivity projections based on hopper capacity were calculated. The results show that increasing the set-point from 90 °C to 120 °C accelerates melting from ±240 s to ±180 s (≈25% faster). Heat transfer analysis confirmed the dominance of conduction (≈329.7 W at 90 °C and ≈471 W at 120 °C), while convection and radiation contributions were much smaller; the total system heat rate was ≈342.7 W (90 °C) and ≈490.8 W (120 °C). The discussion highlights the process trade-off: higher set-points increase production rate and mold filling quality (due to lower melt viscosity), but may raise energy consumption per cycle and require tighter mold temperature control to limit shrinkage/warpage. The practical implications for SMEs are the need for efficiency strategies based on barrel insulation, heater contact area optimization, and correlation of temperature-time settings with quality and energy consumption targets. This study concludes that controlled temperature and heating duration, supported by simple yet targeted thermal design, can improve cycle time consistency, dimensional precision, and energy efficiency in small-scale plastic bolt molding machines.

This article examines the economic defense reforms implemented by China under Xi Jinping's leadership through a literature review. This research aims to examine the key strategies employed by the Chinese government to strengthen its economic resilience amidst global pressures, such as the trade war with the United States, the COVID-19 pandemic, and escalating geopolitical rivalries. The findings indicate that Xi Jinping prioritizes a dual-circulation strategy, namely strengthening domestic consumption while maintaining connectivity with international markets, as a crucial step in addressing global uncertainty. Furthermore, the Made in China 2025 policy serves as a key pillar for promoting technological independence, reducing dependence on imports, and enhancing the competitiveness of domestic industries in strategic sectors such as information technology, renewable energy, and artificial intelligence. Furthermore, through the Belt and Road Initiative (BRI), China seeks to expand its economic influence globally, open new markets, and transfer excess domestic industrial capacity to partner countries. These reforms are not solely oriented toward economic aspects but are also closely linked to political and national security interests. This strategy demonstrates China's systematic efforts to build economic resilience integrated with geopolitical interests, using the economy as an instrument of both soft and hard power. This study demonstrates that Xi Jinping's economic defense reforms are not merely a short-term response to the global crisis, but rather part of a long-term vision to establish China as a dominant global power. Thus, this study emphasizes the importance of understanding China's economic strategy holistically, as these reforms, in addition to significantly influencing domestic dynamics, also have significant implications for the future global economic and political order.

Warfarin (commonly known by its trade name, Coumadin) is an oral anticoagulant that has been widely used for the prevention and treatment of thromboembolic disorders. Despite its clinical benefits, warfarin therapy is complicated by a very narrow therapeutic index and wide inter-individual variability in dose requirements. This variability represents a major challenge for clinicians, as inappropriate dosing may lead to serious adverse outcomes such as bleeding or thrombotic events. A growing body of evidence suggests that genetic polymorphisms are among the most important factors contributing to this variability, particularly those involving the Vitamin K Epoxide Reductase Complex Subunit 1 (VKORC1) gene. VKORC1 encodes a key enzyme that functions as a bottleneck in the vitamin K cycle, playing an essential role in the regeneration of reduced vitamin K (VKH). This active form of vitamin K is required for the γ-carboxylation of vitamin K–dependent clotting factors, including prothrombin and other coagulation proteins. Polymorphisms within VKORC1 can significantly alter the enzyme’s expression and activity, thereby modifying an individual’s sensitivity to warfarin. One of the most clinically relevant variants is the -1639G>A (rs9923231) polymorphism, which reduces VKORC1 transcription and subsequently decreases enzyme activity. Patients carrying the A allele often exhibit increased sensitivity to warfarin and therefore require lower maintenance doses compared to those with the G allele. Understanding these genetic influences not only improves our knowledge of warfarin pharmacogenomics but also highlights the importance of personalized medicine in anticoagulant therapy. Incorporating VKORC1 genotyping into clinical practice could optimize dose prediction, minimize adverse events, and enhance the safety and effectiveness of warfarin therapy. This narrative review aims to provide an in-depth discussion of the complex role of VKORC1 in vitamin K metabolism and its impact on warfarin sensitivity, thereby underscoring the critical relevance of genetic factors in guiding individualized anticoagulation therapy.

This research examines the impact of Indonesia's sugar import policy during the period 2020–2024 through the case study of Thomas Trikasih Lembong. Employing a qualitative methodology with an instrumental case study approach, the study seeks to capture the complexities of strategic commodity trade policies in Indonesia. The analysis reveals that the issuance of sugar import permits to PT Andalas Putra was conducted in violation of existing legal frameworks, particularly Presidential Regulation No. 48/2013, resulting in state financial losses estimated at Rp 400 billion. These irregularities highlight not only weak adherence to regulatory standards but also minimal coordination among relevant government agencies, reflecting the broader challenge of weak good governance implementation. The distributional consequences of this policy were also significant. While downstream industries benefited from increased sugar availability and lower input costs, domestic sugarcane farmers and the national sugar industry suffered substantial losses. The oversupply condition triggered by import policy mismanagement led to a decline in local sugar prices, producing welfare transfers that disproportionately disadvantaged rural farming communities. These findings underscore the structural vulnerability of agricultural stakeholders when state institutions fail to balance industrial and farming interests in policy formulation. Furthermore, the imposition of a 4.5-year prison sentence on the policymaker involved has sparked discourse on the criminalization of public policy, raising debates over the line between policy failure and corruption in governance. In light of these findings, the study provides several recommendations. These include strengthening inter-agency coordination mechanisms, developing early warning systems to monitor commodity market dynamics, reforming the regulatory framework governing import permits, and designing adaptive policy instruments capable of mitigating welfare risks while optimizing strategic commodity management. Overall, this study contributes to the discourse on governance, accountability, and policy reform in Indonesia’s strategic trade sector, particularly in relation to sugar as a vital commodity.

The war between India and Pakistan has had a devastating impact on the economies of both the countries directly involved and those indirectly affected. The economic impacts of this armed conflict include significant infrastructure damage, reduced production capacity, soaring inflation, rising unemployment, and reduced investment flows. This geopolitical instability has also fueled uncertainty in global financial markets, triggering a "flight to safety" phenomenon, a shift in capital and investment to countries or instruments perceived as safer, such as US government bonds or gold. For Indonesia, this situation has the potential to significantly disrupt national economic stability. One impact is a reduction in foreign direct investment (FDI) inflows, as investors tend to hold back or relocate their investments to more geopolitically stable countries. Furthermore, pressure on the rupiah exchange rate could increase due to global financial market volatility and a decline in international investor confidence. The conflict could also hamper Indonesia's export traffic, particularly to countries with close trade ties with India and Pakistan. Furthermore, these tensions could disrupt global supply chains, particularly for energy and food commodities, many of which pass through strategic trade routes. If the conflict drags on, the price of crude oil and other raw materials could potentially rise sharply, which in turn would increase domestic production costs. This would have a direct impact on inflation and public purchasing power. This situation further complicates the management of Indonesia's monetary and fiscal policies, which currently face significant challenges, such as the imminent maturities of large government debt and a still-widening state budget deficit. The government must take strategic steps to maintain domestic economic stability, strengthen foreign exchange reserves, and encourage export market diversification to reduce over-reliance on conflict-prone countries.

The potential war between India and Pakistan poses significant risks to the Indonesian economy, as it is expected to exacerbate uncertainty in the global financial market. Such geopolitical tensions often trigger a ‘flight to safety,’ where capital flows shift to countries considered stable, leading to reduced foreign direct investment (FDI) in emerging markets like Indonesia. This scenario is likely to place additional pressure on Indonesia’s exchange rate, further destabilizing its financial position. One of the key impacts of the looming India-Pakistan war on Indonesia is its effect on monetary and fiscal management. The Indonesian government is already facing significant challenges, including managing a large amount of maturing debt and grappling with a growing budget deficit. The war would complicate these efforts, making it more difficult for the government to stabilize the economy and implement effective policies. Indonesia’s export sector will also be affected, as India and Pakistan are two of the country’s main trading partners, especially for key commodities like crude palm oil (CPO) and coal. India is Indonesia’s 4th largest export destination, accounting for approximately 9% of total exports, while Pakistan represents around 1.9%. Any disruption in trade with these countries, due to the war or political instability, could significantly hurt Indonesia’s export revenues and negatively affect industries reliant on these markets. Moreover, Indonesia is already facing challenges from the United States, which has imposed reciprocal tariffs worth 32% on Indonesian products. This trade tension, combined with the geopolitical instability from the India-Pakistan conflict, will add further strain to Indonesia’s trade balance. The combination of these factors could lead to slower economic growth, reduced investor confidence, and potentially higher inflation, as the country faces multiple external and internal economic pressures.

The reciprocal tariff policy has a significant impact on a number of countries, including Indonesia. In this scheme, Indonesian non-oil and gas products are subject to a tariff of 32% when entering the US market. Such a high tariff places Indonesian exporters in a less competitive position compared to other countries that have more favorable trade arrangements with the United States. This condition becomes more complex when viewed in the broader context of the US-EU trade war, which creates uncertainty and turbulence in the global economy. Indonesian exports are affected both directly and indirectly. Indirect impacts can be seen from disruptions to the global supply chain, the slowdown in the world economy, and decreased global demand. As global production networks become increasingly interconnected, any disruption in major economies will ultimately suppress demand for Indonesian export commodities. This means that even if Indonesian products are not directly targeted, the ripple effects of global trade tensions will still hinder Indonesia’s export performance. For instance, reduced consumption in Europe and the US due to rising product prices and inflation will diminish market opportunities for Indonesian goods.On the other hand, direct impacts arise because several Indonesian products have been explicitly subjected to tariffs by the US government. These include textiles and textile products (TPT), electronics and their components, footwear, furniture, and palm oil (crude palm oil/CPO). Such tariffs significantly reduce Indonesia’s competitiveness in the US market, potentially leading to decreased export volumes, lower revenues for domestic industries, and job losses in export-oriented sectors. Furthermore, the policy also makes European products much more expensive in the US market, which worsens the global supply chain, increases logistics costs, triggers inflation, and escalates uncertainty in international trade.

The relationship between Makassar sailors and the Yolngu Aboriginal people in northern Australia since the 17th century shows an early form of peaceful and mutually beneficial inter-community diplomacy. The sea cucumber trade activity became the entry point for deep economic cooperation and cultural exchange, leaving a significant influence on the social and cultural identity of the Yolngu people. Using a historical method approach, this article explores archaeological, linguistic, and oral narrative evidence that strengthens the traces of this interaction. In the modern context, this historical legacy is an important foundation for Indonesia's cultural diplomacy and soft power, while strengthening strategic cooperation with Australia in the fields of maritime, culture, and regional security.
