This study analyzes the economic phenomenon known as the "Purbaya Effect" in the Indonesian capital market during the second half of 2025. This phenomenon is characterized by a significant surge in the Jakarta Composite Index (IHSG), which broke the All-Time High (ATH) record 21 times within four months following the appointment of Purbaya Yudhi Sadewa as Minister of Finance. Using a mixed-methods approach combining quantitative market data analysis and qualitative policy review, this research finds that the "Purbaya Effect" is driven by aggressive liquidity injection policies (Rp 200 trillion), institutional trust built during his tenure at LPS, and strong narrative economics. However, this study also identifies significant risks related to exchange rate volatility and potential economic overheating. The findings suggest that while the "Purbaya Effect" successfully restored short-term investor confidence, long-term sustainability depends on the balance between growth acceleration and macroeconomic stability.

This study aims to determine and analyze service waiting times, identify the root causes of long queues, and develop a strategy to improve service performance at the 5361137-gas station (SPBU) at the Surabaya-Gresik Toll Rest Area. The research method used is a mixed-methods approach with an exploratory sequential design. This study combines quantitative analysis using Queuing Theory to measure system performance (arrival rates and service times) and descriptive qualitative analysis using a Fishbone Diagram. Data were collected through direct observation, interviews, and g-form techniques. The results indicate that the current queuing system performance is in a critical or severe condition, indicated by a server utilization rate of 0.94 to 1.02 during peak hours. The average time spent by vehicles in the system is 14.3 minutes, of which 9.6 minutes (67%) is spent waiting in the queue. Fishbone diagram analysis revealed that the root cause of the main problem lies in the complex interaction of factors: Machine factors (EDC signal failure and pump repair downtime), Human and Method factors (implementation of static shifts and reactive maintenance), and Environmental factors (narrow layouts that hinder large vehicle maneuvers). As a solution, this study formulated a hybrid improvement strategy that includes short-term business process engineering (the use of Floating Staff and lane segregation) and long-term investment in additional pumps to change the queuing model from Single Channel to Dual Channel. This strategy is expected to reduce the utility level to a safe zone below 0.80 with a target waiting time of 3–5 minutes.

The concept of the Day of the LORD in the prophetic tradition of the Old Testament is often narrowly understood as a day of victory and salvation for Israel. However, the book of Amos offers a sharp critique of such an interpretation. This study aims to examine the eschatological meaning of the Day of the LORD in Amos 5:18–24 as a moment of judgment and restoration. This research employs a qualitative method with a biblical hermeneutical approach, particularly historical-contextual and theological analysis of Amos 5:18–24. The findings indicate that the Day of the LORD is portrayed as a divine event that brings judgment against social injustice, religious hypocrisy, and ethical deviation among the people of Israel. At the same time, the text opens the possibility of restoration through the demand for justice and righteousness as expressions of true worship. Therefore, Amos’s eschatology is not speculative about the future but functions as a prophetic critique that calls for repentance and social transformation. This study affirms that the Day of the LORD remains contextually relevant for the contemporary church in integrating faith, worship, and social justice as an inseparable unity.

This community service activity aims to improve the efficiency of inventory management at Zencha MSMEs through the design and implementation of a Standard Operating Procedure (SOP) and a spreadsheet-based inventory recording system. Prior to this program, Zencha MSMEs managed its inventory manually without written procedures, which often caused stock discrepancies, delays in restocking, and difficulties in monitoring raw material availability. The methods used in this activity included observation, interviews, SOP design, system socialization, and direct implementation assistance. The SOP was structured to regulate the process of receiving, recording, storing, and using raw materials, while the spreadsheet template functioned as a digital tool to record stock movements automatically. The results show that after the implementation, inventory management became more organized, transparent, and measurable. The business owner was able to monitor stock levels more accurately, determine restocking time more effectively, and reduce the risk of stock shortages. In addition, employees demonstrated better discipline in recording inventory according to established procedures. This program proves that the implementation of SOP and digital-based inventory recording can significantly improve operational efficiency and support the sustainability of micro and small enterprises.

Closed distal humerus fractures are injuries involving the distal portion of the humeral bone without disruption of the overlying skin, most commonly resulting from direct trauma such as the impact of a heavy object or blunt force to the elbow region. Although relatively uncommon in adults, this type of fracture presents considerable complexity due to its proximity to neurovascular structures and the elbow joint. Diagnosis is established through targeted anamnesis, comprehensive physical examination, and radiographic imaging in two standard projections to assess the location, fracture pattern, and degree of displacement. Additional modalities such as computed tomography (CT) may be indicated in cases of articular or comminuted fractures to enhance operative planning. Management depends on fracture stability, the extent of displacement, and the condition of surrounding soft tissues. In unstable or comminuted fractures, operative intervention such as Open Reduction and Internal Fixation (ORIF) is the preferred approach to restore bony continuity, reconstruct articular anatomy, and enable early mobilization. The primary therapeutic goals are to optimize elbow function, maintain joint stability, and prevent long-term complications including stiffness, malunion, delayed union, or non-union. Postoperative rehabilitation plays a crucial role in preventing restricted range of motion and restoring extremity strength. This case report describes a 49-year-old male with a comminuted closed distal humerus fracture of the left arm following direct trauma from a heavy object. The patient underwent complete clinical and radiological evaluation and was treated with ORIF. Early outcomes demonstrated adequate restoration of stability and alignment, affirming that accurate diagnostic assessment and timely intervention significantly contribute to optimal functional recovery of the affected extremity.

The increasing global energy demand drives the search for efficient and sustainable renewable energy solutions. Solar panels have become one of the most widely used technologies; however, their efficiency remains limited when installed in a static position. This research aims to analyze the performance of a single-axis auto tracking system on a 10WP solar panel integrated with the Internet of Things (IoT) for real-time monitoring, specifically in powering a portable powerbank. The research method employed was a quantitative experimental design with three testing scenarios: powerbank charging using an auto-tracking solar panel, a static solar panel, and conventional household electricity as a comparison. Charging data were collected via an IoT system integrated with the Blynk application in real-time. The results indicate that the auto-tracking system increased charging efficiency by around 10%, compared to only 6% with a static panel in one hour. This performance is nearly equal to household electricity charging, which reached approximately 10–11%. The study concludes that the single-axis IoT-based auto-tracking system significantly enhances the performance of small-scale solar panels and holds strong potential for portable energy solutions in remote areas.

This research is motivated by the high risk of fatigue experienced by ship crews during voyages, which directly affects occupational safety and mental well-being. Fatigue arises from long working hours, inadequate rest time, heavy workloads, and extreme environmental conditions such as high temperatures, engine noise, and vessel vibrations. On the MT. Sultan Mahmud Badaruddin II, the problem becomes more complex due to the tight work rhythm, short berthing periods, and fast, repetitive loading–unloading activities. Harsh weather conditions, short but intensive sailing distances, and limited relaxation facilities make the crew increasingly vulnerable to both physical and mental fatigue. In addition, a work culture that tends to be authoritarian and lacks communication exacerbates psychological pressure, especially when crew members find it difficult to report their fatigue to superiors. This study uses a qualitative method through direct observation and interviews with all crew members in the deck and engine departments. The aim is to analyze the influence of the work environment and work culture on fatigue levels onboard. The results show that environmental factors such as high temperatures, narrow workspaces, and vessel instability significantly affect physical fatigue. Meanwhile, mental fatigue is triggered by ineffective communication, hierarchical pressure, and an unsupportive work culture. These findings align with the perspectives of Mathis and Jackson and comply with the provisions of the STCW 2010 and MLC 2006, which emphasize the importance of regulating working hours and fatigue management. Overall, optimizing rest hours, improving the work environment, and reforming organizational culture are required to reduce fatigue risks.

Right now, the utilization of data and correspondence innovation fundamentally affects different business areas, including producing. One arising idea is e-business, otherwise called electronic business. This idea underlines data exchanging and paperless exchanges through different innovations like Electronic Trade of Data (EDI), email, electronic notice sheets, electronic assets move, and other organization based propels. An e-business data framework is a gadget, innovation, or system that uses equipment, programming, organizations, and human insight to interface, do exchanges, and complete different hierarchical exercises without being restricted by time or area. The utilization of e-business data frameworks is a significant instrument that associations use to further develop business activities at the nearby and worldwide level. Indonesia is one of the trailblazers in web-based business and internet business. Nonetheless, the potential presented by e-business haven't completely taken advantage of by business affiliations.

This study aims to determine the effectiveness of goat manure and liquid organic fertilizer made from coffee husk waste on the growth of Java tea (Orthosiphon aristatus) cuttings. The study used a factorial Randomized Block Design (RBD) consisting of two factors with 48 plots. The first factor was the application of goat manure, symbolized as “S,” with four treatment levels: S0 (without goat manure), S1 (250 g/polybag), S2 (350 g/polybag), and S3 (450 g/polybag). The second factor was the application of liquid organic fertilizer made from coffee husk waste, symbolized as “K,” with four treatment levels: K0 (0 ml/L water/polybag), K1 (30 ml/L water/polybag), K2 (60 ml/L water/polybag), and K3 (90 ml/L water/polybag). Thus, there were 16 treatment combinations with three replications. The parameters observed in this study were the time of shoot emergence, number of shoots, shoot length, number of leaves, plant height, and survival percentage. The results showed that the application of goat manure and liquid organic fertilizer from coffee husk waste on the growth of Java tea (Orthosiphon aristatus) cuttings had no significant effect on all observed parameters.

A decline in performance in automatic motorcycles that have been used for a long time is a common problem caused by wear and tear on the Continuously Variable Transmission (CVT) system. This condition results in a reduction in the clamping force of the V-belt on the pulley, causing slippage and a decrease in transmission capacity. Based on the manufacturer's specifications, the torque is 8.32 Nm at 5500 rpm, while the test results show a torque of 7.41 Nm at 6500 rpm, a decrease of 10.9%. The study aims to analyze the effect of variations in pulley angle and surface roughness on the torque value of a 108 cm³ automatic motorcycle as a method to restore transmission performance without replacing the main components. The pulley angles tested were 14°, 13.8°, and 13.5°, while the surface roughness was varied based on the turning process with cutting inserts having nose radii of 0.2 mm, 0.4 mm, and 0.8 mm. The testing was conducted using a dynamometer at an engine speed range of 6000 – 9000 rpm. The results showed that the combination of a 13.8° pulley angle with a 0.2 mm cutting insert nose radius produced a torque of 7.41 Nm at 6500 rpm, an increase of 8.2% compared to the standard 14.5° configuration, which only produced 6.85 Nm. Modifying the pulley angle and surface roughness was proven to increase the V-belt clamping force, thereby improving transmission performance.

In the modern computing era, servers face significant challenges in data storage due to hardware failures, cyber attacks, or human errors. The problem highlighted focuses on the impact of file systems on three critical aspects: data integrity (accuracy and consistency of data without corruption), data recovery (the ability to restore data after a failure), and failure resilience (fault tolerance, such as redundancy and journaling to prevent downtime). The main issue is that traditional file systems like FAT32 or NTFS are often susceptible to fragmentation, metadata loss, or long recovery times, which can lead to data loss of up to 20-30% on enterprise servers, especially in high-traffic environments like cloud computing.A simple problem-solving process is conducted through a straightforward comparative analysis approach: (1) A literature review of popular file systems (ext4, ZFS, Btrfs); (2) Failure simulations using tools like fsck and stress testing on virtual servers (e.g., via KVM or Docker); and (3) Measuring performance metrics with benchmarking tools like Bonnie++ for I/O throughput, recovery time, and error rates. This process is designed to be simple, requiring only a virtual lab setup without expensive hardware, and is analyzed quantitatively with descriptive statistics.The solution to the problem indicates that advanced file systems like ZFS or Btrfs provide significant improvements: data integrity is up to 95% more secure through automatic checksums, data recovery is achieved in minutes through snapshots and RAID integration, and failure resilience is higher with copy-on-write features. The main recommendation is to migrate to journaling-based file systems for servers, combined with automated backups, which can reduce the risk of downtime by up to 50%. This research provides practical guidance for system administrators to enhance server reliability without excessive additional costs.

This study aims to examine public minibus drivers in Medan from the perspectives of citizenship and liberalism. The research method used is descriptive qualitative with data collection techniques through in-depth interviews, participatory observation, and documentation. The results show that public minibus drivers enjoy individual freedoms, such as determining their working hours, choosing their rest times, and competing for passengers. This freedom is seen as a form of self-sovereignty in line with the principles of liberalism. However, this freedom also gives rise to contradictions, namely economic uncertainty, the burden of daily deposits, and the absence of social security and legal protection. The emergence of application-based transportation services further exacerbates the gap, as angkot drivers feel they experience inequality in terms of access to technology, regulations, and government support. This condition demonstrates the weak role of the state in guaranteeing their citizenship rights, especially those related to welfare and job protection. Thus, this study emphasizes that the principle of freedom in liberalism cannot be separated from the state's responsibility to achieve social justice. More equitable policies, technological support, and social protection for public minibus drivers are important steps to ensure that individual freedom is in line with citizenship rights.

The 2020–2024 period is a crucial time for the Indonesian economy, which is facing severe pressure due to the COVID-19 pandemic and global economic dynamics. This study aims to analyze the development of the national economic condition over the past five years through key macroeconomic indicators, such as Gross Domestic Product (GDP), Foreign Direct Investment (FDI), forest area, industrial sector contribution, high-tech exports, domestic credit, trade in goods, and gross national income per capita (GNI per capita). The method used is descriptive quantitative based on data from the Central Statistics Agency (BPS) and secondary sources from national and international institutions. The results show that despite a contraction in 2020 due to the pandemic, the recovery process has been rapid since 2021, with stable economic growth in the range of 5% until 2024. Increased GNI per capita, improved foreign investment flows, and the expansion of economic digitalization are key factors strengthening national resilience. However, challenges remain, such as a decline in the industrial sector's contribution and a reduction in forest area. These findings confirm that Indonesia's economic development is moving toward a structural transformation oriented toward sustainability, sector diversification, and social inclusiveness. Overall, the 2020–2024 period reflects a phase of recovery and restructuring of the economic foundations toward achieving the Vision of a Golden Indonesia 2045 with global competitiveness.

This study aims to analyze the influence of the use of gadgets on the reading interest of students at SMAN 1 Tolitoli. The background of this research departs from the phenomenon of declining students' interest in reading in the digital era, where students spend more time using gadgets for entertainment such as social media, online games, and watching videos than reading books or lesson literature. The low number of visits to school libraries, which only increased before the exam, is a major indicator of the weakening of the literacy culture among students. This study uses a quantitative approach with data collection techniques through observation, questionnaires, and documentation. Data analysis was carried out by normality test, t-test, and determination coefficient (R²) to determine the magnitude of the influence of gadgets on reading interest. The results of the study show that there is a significant influence between the use of gadgets on students' reading interest. The tcalculated value of 4,028 > ttable 1,655 indicates that H₀ is rejected and Hₐ is accepted. The use of gadgets contributed 9.8% to the reading interest of students at SMAN 1 Tolitoli, while the rest was influenced by other factors such as family environment, learning motivation, and support for literacy facilities at school.
