This study focuses on the analysis of traffic density in Jember City, particularly at the Wirolegi Intersection, which is known to have a high density level. This condition often triggers congestion that hinders public mobility, so that appropriate and data-based handling efforts are needed. The purpose of this study is to identify and analyze the level of density at critical congestion points through a statistical approach using the One Way ANOVA method. The research method used is quantitative descriptive with a descriptive observational approach. Primary data was collected directly through a field survey in 2025 at the Wirolegi Intersection as one of 3 intersections in Jember City. The data obtained were then processed using normality tests, homogeneity tests, and One Way ANOVA with the help of SPSS software. The results of the analysis show that the traffic flow density on the three routes studied, namely Jalan Gunung Haryono, Jalan Brigjen Katamso, Jalan Yos Sudarso, does not show a significant difference. The significance value of the ANOVA test is greater than 0.05 which indicates the similarity of density levels between routes. Further testing (post hoc testing) also strengthens this finding. The conclusion of this study shows that handling congestion at the Wirolegi Intersection needs to be done comprehensively through traffic control and evaluation of the transportation system to improve smoothness and mobility in Jember City.

This study is grounded in Stakeholder Theory and Signaling Theory to explain the relationships among the variables. The sample was determined using purposive sampling, resulting in 29 companies. The data analysis techniques applied include Pearson correlation analysis and multiple linear regression to examine both the simple relationships and the effects of corporate social responsibility disclosure and profitability on firm value. The results indicate that corporate social responsibility disclosure has a negative relationship with firm value, while profitability shows a positive and significant relationship with firm value.

Background: The development of modern manufacturing systems requires production scheduling strategies that not only improve productivity but also optimize energy utilization. Multi-machine production systems with job-shop configurations exhibit high complexity due to dynamic interactions between machines, job queues, and varying processing times, making conventional scheduling methods less effective in handling changing operational conditions. Objective: This study aims to develop and evaluate a reinforcement learning based production scheduling approach to improve production efficiency while reducing energy consumption in multi-machine manufacturing systems. Methods: This research employs a job-shop based multi-machine production simulation model as the experimental environment. The scheduling problem is formulated as a Markov Decision Process, enabling the implementation of reinforcement learning algorithms, namely Q-learning and Deep Q-Network, to learn optimal scheduling policies through interaction with the simulation environment. Energy consumption parameters are incorporated into the reward function so that the learning agent can consider energy efficiency in the scheduling decision-making process. System performance is evaluated using three main metrics, namely energy consumption, throughput, and makespan. Results: The experimental results show that the reinforcement learning based scheduling approach achieves better performance compared to conventional scheduling methods, resulting in lower energy consumption, higher job completion rates, and shorter production completion times within the multi-machine manufacturing system.

Presidential Instruction Number 1 of 2025 concerning State Expenditure Efficiency gave rise to a fiscal paradox at the beginning of the new administration, with a cut of Rp306.69 trillion facing a 17.9% APBN deficit for flagship programs such as Free Nutritious Meals, which triggered doubts about public trust, especially students at the University of Jambi affected by the BOPTN adjustment. This study analyzes the influence of student perceptions on the dimensions of effective-efficient (X1) and transparent-accountable (X2) policies on public trust (Y) as an indicator of government legitimacy. A quantitative survey approach was applied to 400 active students at the University of Jambi (proportional random sampling using the Slovin e=0.05 formula), with SPSS multiple linear regression analysis after classical assumption testing, validity (r> r-table), and reliability (Alpha Cronbach's 0.920 (x1); 0.949 (x2); 0.918 (y)). The results show a significant simultaneous effect (F=200.951; sig=0.000), partial X1 is dominant (t=7.116; β=0.162; sig=0.000) and X2 is significant (t=5.532; β=0.110; sig=0.000), with R²=0.503 explaining 50.3% of the variation in trust. The findings confirm the theory of Easton (1965) and Weber (1947) that efficiency performance evaluation shapes trust, so it is recommended that a real-time APBN dashboard, transparent communication to regional PTNs, and fiscal literacy strengthen the legitimacy of good governance.

Oil and natural gas are vital resources for the state, and their management must be carried out carefully and transparently. However, the complexity of existing management is often exploited by irresponsible parties to commit corruption that harms state finances. This study aims to analyze how criminal law regulates the accountability of perpetrators in the oil management corruption case at Pertamina in 2025. The method used is normative juridical, by reviewing laws and regulations regarding corruption, state-owned enterprises (BUMN), and related legal literature. The results of the study indicate that criminal liability in this case is not only directed at individual officials, but also corporations or companies. This is because the element of mens rea (malicious intent) was found in the act. Therefore, law enforcement must focus more on recovering state losses and improving Pertamina's internal oversight system, rather than simply imprisoning the perpetrators.

This study explores the integration of customary law and government regulations in environmental protection, emphasizing the role of community perceptions in shaping effective legal frameworks. Marginal ecosystems, such as coastal areas, urban fringes, and sacred natural sites, often face vulnerability due to fragmented governance systems that fail to coordinate customary practices with formal legal structures. The research investigates how integrating local traditions and state regulations can enhance biodiversity conservation, improve community engagement, and ensure the long term sustainability of environmental management efforts. Findings reveal that when customary laws are formally recognized and incorporated into state regulations, they significantly enhance the legitimacy and effectiveness of conservation policies. Communities in regions like Bali, Indonesia, and Pacific Islands have shown that hybrid legal approaches, which respect traditional ecological knowledge, result in greater participation and trust in conservation activities. However, challenges such as administrative complexity, lack of standardized guidelines, and the need for adequate funding and support for community based governance hinder the full potential of this integration. The study highlights the importance of simplifying legal processes and fostering mutual understanding between customary practices and formal regulations to achieve successful ecosystem protection. This research emphasizes the need for policy reforms that ensure the inclusion of customary law in environmental governance frameworks, ultimately promoting a more inclusive, adaptive, and sustainable approach to managing marginal ecosystems.
