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.

Solid waste management in Makassar City constitutes a strategic issue that extends beyond technical and administrative concerns to encompass legal, ethical, and socioreligious dimensions. Although the local government has established regulatory frameworks and policy instruments for waste management, empirical conditions reveal a persistent gap between legal norms and their implementation, as reflected in high waste generation rates, weak source segregation, limited public participation, and increasing pressure on landfill capacity. This study aims to analyze the effectiveness of waste management in Makassar City from the perspective of Islamic law and to examine the potential integration of Sharia principles in strengthening sustainable environmental governance. The research employs a qualitative approach with a descriptive-analytical design based on policy analysis, literature review, and theoretical synthesis of Islamic legal doctrines, particularly maqāṣid al-sharīʿah and fiqh al-bī’ah. The findings indicate that, despite the existence of adequate local legal instruments, waste management practices remain ineffective due to insufficient internalization of ethical values, weak law enforcement, and limited behavioral change within society. From the perspective of Islamic law, these conditions demonstrate the incomplete realization of the principles of amanah (trust and responsibility), maslahah (public interest), and the prevention of harm (lā ḍarar wa lā ḍirār) in both governmental practice and public conduct, thereby undermining the objectives of protecting human life and the environment. The implications of this research highlight the importance of synergizing positive law and Islamic legal principles to promote environmentally sustainable governance oriented toward long-term public welfare.

This study examines the implementation of the Minister of Marine Affairs and Fisheries Regulation Number 7 of 2024 concerning the Management of Lobster, Crab, and Blue Swimming Crab in East Kalimantan. As a strategic policy, the regulation aims to ensure sustainable fisheries management through provisions on minimum catch sizes, restocking mechanisms, traceability systems, and law enforcement against illegal fishing and trade. Using an empirical juridical approach, this research collected primary data through questionnaires distributed to fisheries officers, coastal communities, fishers, and aquaculture business actors in East Kalimantan. The results show that the implementation of Regulation No. 7/2024 is generally categorized as moderately effective, with an average Likert score indicating limited but positive compliance. Respondents acknowledged the importance of sustainability principles embedded in the regulation; however, significant challenges persist, including insufficient formal socialization, weak field monitoring, lack of supporting facilities, and inconsistent coordination among implementing agencies (BARANTIN, PSDKP, and local fisheries officers). Qualitative responses highlight that many stakeholders still lack understanding of technical provisions such as minimum size requirements and restocking obligations. The study concludes that while the regulatory framework is normatively comprehensive and aligned with sustainable fisheries principles, its practical effectiveness remains constrained by institutional and socio-cultural factors. Strengthening community engagement, increasing inter-agency coordination, and enhancing enforcement capacity are crucial to optimizing the policy’s impact on the sustainable management of lobster, crab, and blue swimming crab resources in East Kalimantan.

This study examines the readiness of elementary school teachers to implement AI-based learning in the era of artificial intelligence, as technological advancements increasingly influence instructional practices in basic education. Despite the growing potential of artificial intelligence to support teaching and learning processes, empirical evidence regarding teachers’ preparedness at the elementary level remains limited. This study employed a descriptive quantitative research design involving 18 elementary school teachers. Data were collected using a structured questionnaire consisting of 15 Likert-scale items measuring technological skills, knowledge of artificial intelligence, attitudes toward AI, pedagogical readiness, and infrastructure support. Descriptive statistical analysis revealed that the overall mean score of teachers’ readiness was 4.08, indicating that teachers are generally ready to adopt AI-based learning. Technological skills emerged as the strongest aspect of readiness, reflecting teachers’ familiarity with digital tools and instructional technologies, while infrastructure and institutional support obtained the lowest mean score, highlighting challenges related to facilities, access to technology, and policy support. These findings suggest that although elementary school teachers demonstrate positive readiness and attitudes toward AI-based learning, effective and sustainable implementation requires strengthened institutional support, improved infrastructure, and continuous professional development to maximize the educational benefits of artificial intelligence in elementary education.

This study aims to analyze the effect of the implementation of the Intelligent Tutoring Sistem (ITS) based on Artificial Intelligence (AI) on improving the understanding of mathematical concepts, especially in fractional and basic geometry materials, in Class V students of SD Negeri 2 Badran, Temanggung Regency. The research method used was a quasiexperimental experiment with a Non-equivalent Control Group Design. The research sample consisted of 48 students who were divided into two groups, namely the experimental group (n=24) who received learning with the help of AI-based ITS, and the control group (n=24) who received conventional learning with lecture methods and practice questions. The research instrument is in the form of a test of understanding of mathematical concepts that has been validated by experts and tested for reliability. Data were analyzed using parametric statistical tests of the Independent Sample t-test and N-Gain Score to measure the improvement. The results showed that there was a significant difference in understanding of mathematical concepts between the experimental group and the control group. The average post-test score of the experimental group (82.45) was significantly higher than that of the control group (70.12) with a p< value of 0.05. N-Gain analysis showed that the improvement in conceptual understanding in the experimental group was in the "moderate" category (g=0.56), while the control group was in the "low" category (g=0.32). These findings indicate that AI-based ITS is effective in improving students' understanding of mathematical concepts. The advantages of the system lie in its ability to provide instant feedback, personalize materials according to learning pace, and present interactive materials, thus helping to better construct students' conceptual understanding. It is recommended that schools consider the integration of ITS technology as a supplementary tool in mathematics learning at the elementary level.

The rapid development of urban areas has created significant challenges in mobility, particularly the increasing use of private motor vehicles, which contributes to traffic congestion, air pollution, greenhouse gas emissions, and a decline in the quality of urban life.
