Indonesia is the world’s second largest contributor of plastic waste entering the oceans, where it degrades into microplastics smaller than 1 micron. The use of bioplastics is therefore essential to mitigate environmental pollution. One promising alternative is starch–cellulose blend bioplastic derived from empty fruit bunches (EFB) of oil palm. Indonesia produces about 56.35 million tons of EFB annually, containing approximately 40% cellulose, which makes it a potential raw material for bioplastic production, although commercialization has not yet been realized. Environmentally, converting EFB into bioplastics within the palm oil value chain represents a sustainable waste recycling strategy that transforms solid residues into higher-value products. In this design, soda cooking technology is employed to extract cellulose from EFB, utilizing about 16% of waste from a crude palm oil (CPO) mill with a capacity of 30 tons of fresh fruit bunches (FFB) per hour. The starch–cellulose blend bioplastic pellets are formulated using gelatinized cassava starch as the polymer matrix, glycerol as a plasticizer, polyvinyl alcohol (PVA) as a stabilizer, and cellulose as a filler. The designed production capacity of the EFB-based starch–cellulose bioplastic plant is 16,500 tons per year. This bioplastic industry is expected to contribute positively to achieving eight Sustainable Development Goals (SDGs), including Goals 1, 8, 9, 12, 13, 14, 15, and 17, thereby supporting Indonesia’s commitment to sustainable industrial development and a cleaner environment.

This study elaborates on the concept of humanism in Islamic educational philosophy by highlighting in greater depth the role of humans as caliphs on earth. Humanism from an Islamic perspective not only focuses on humans as rational beings but also emphasizes the moral, spiritual, and social responsibilities inherent in the mandate of the caliphate. This study applies a qualitative approach with a literature study, where data is obtained from various written sources such as scientific articles and academic publications that discuss humanism in Islamic education and the concept of the human caliphate. The data collection process is carried out through searching, selecting, and organizing literature relevant to the focus of the study. The collected data are then analyzed using descriptive-qualitative techniques through the stages of simplifying information, grouping findings, and formulating systematic conclusions. The results of the study indicate that the position of humans as caliphs requires the development of intellectual, ethical, and spiritual potential in an integrated manner in the educational process. Therefore, Islamic education needs to be directed towards a holistic humanization process, which not only strengthens reasoning and social character but also fosters a transcendental awareness of human relationships with God, fellow humans, and nature. Thus, humanism in Islamic education is not secular, liberal, or anthropocentric, but is firmly rooted in divine values ​​that harmoniously unite the divine and human dimensions.

Equal access to health services is a fundamental right of citizens. However, vulnerable groups such as beggars are often neglected because they do not have valid residence documents. The Medan City Government launched the Medan Berkah Health Insurance Program (JKMB) to support universal Health Coverage, allowing free health services only with a Medan ID card. This study aims to assess the implementation of JKMB on beggars in Medan City by using the implementation suitability model from David C. Korten, which emphasizes the relationship between programs, organizations, and beneficiaries. The method used is a descriptive qualitative approach, with data collection through in-depth interviews, observations, and documentation studies. Informants consisted of beggars without identity who had been disciplined by Social Services, program Implementation officers, and academics in the field of social welfare. The results showed that JKMB can only be accessed by beggars while under the supervision of Social Services, through temporary identities such as "Mr. X". After being repatriated (reunification), access to health services cannot be continued due to the absence of An ID. The Program has not been able to reach marginalized groups on an ongoing basis, and there has been no integration of cross-sector data systems. The findings expose the discrepancy between program design and Target conditions, highlighting the importance of more inclusive policy reformulation, facilitation of identity ownership, and inter-agency coordination to create equitable and sustainable health access for all citizens

Continuous chemical control of rat pests (Rattus spp.) can sometimes lead to resistance and resurgence problems, and even some cases of inaccurate targeting ultimately killing livestock. The idea of ​​​​repelling rats in rice fields using vibrations of crickets and other natural animals transmitted via radio has been done and the results are quite optimal for rat control, but it has not been done in corn cultivation. The purpose of this study was to determine the effect of cat sound audio on the intensity of rat pest attacks (Rattus spp.) in corn (Zea mays L.) plantations. The research location was in a farmer's land owned by a farmer in Dagan Village, Solokuro District, Lamongan Regency. Observations were carried out on two corn fields, each measuring 1400 m2 with a distance of 1 meter between the two fields. Determination of sampling points using the diagonal method, each into 5 sub-observation plots. In each sub-plot, markers were placed as sampling points. Audio with cat and bird sounds was played continuously from 05.00 pm - 07.00 am. Observations were conducted at 7:00 a.m. at all sampling points at 30 and 60 days after planting. Observations were conducted for three days using audio and three days without audio. Damage symptoms were observed directly at each sampling point. Corn plants showing symptoms were then recorded and analyzed using the Damage Intensity formula. Observations showed that the use of cat sound audio was able to reduce the level of rat infestation. At 30 days after planting, the damage percentage was reduced by 8.33%. Meanwhile, at 60 days after planting, the damage percentage was reduced by 18.33%.

The UNAMA Library employs information systems to enhance its academic services. Nevertheless, its administrative framework continues to encounter obstacles, such as inadequate service system support for users, constrained resources allocated for the management and upkeep of the system, an absence of standardized protocols for addressing technical challenges, and insufficient assessment system efficacy. If these issues remain unaddressed, the operational effectiveness of the library information system will be compromised, thereby thwarting the objective of delivering dependable information services. This investigation seeks to illuminate the maturity level of information system governance as delineated by COBIT 2019 within the Decision Support Systems (DSS) domain, specifically focusing on the DSS01 (Manage Operations) and DSS02 (Manage Service Requests and Incidents) processes. The findings suggest that the degree of information system governance capability the UNAMA Library is situated at the Established Process level (level 3), signifying that the process has undergone implementation; however, it has yet to be comprehensively documented and consistently evaluated. Moreover, a disparity persists between the existing state and the anticipated capability level of the organization, particularly concerning IT operations management, the standardization incident handling, and the documentation of operational procedures. An elucidation of the expected level is articulated, especially in terms of operational standards, incident documentation, and IT infrastructure oversight. Recommendations encompass the formulation of standard operating procedures (SOPs), the enhancement of documentation practices, and periodic assessments grounded in COBIT 2019. These findings are anticipated to assist libraries in augmenting the efficacy of information systems governance and the quality of IT services.

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.

The epistemology of modern science develops with the assumption that neutrality and objectivity distinguish facts from values. This belief leads to the reduction of values, especially those related to ethical, metaphysical, and spiritual values, during the development of science. The purpose of this paper is to examine the problem of value reduction in the epistemology of modern science and to examine the Islamization of science as an epistemic alternative. This research method is qualitative, literature-based, and critical-philosophical. Epistemological critiques of value-free science, based on positivism and modern empiricism, and a study of the theory of the Islamization of science by Syed Muhammad Naquib al-Attas and Ismail Raji al-Faruqi are used to complete the analysis. The results of this study indicate that the epistemological separation between facts and values ​​in contemporary science leads to a decline in values. The Islamization of science offers an alternative epistemic framework that positions science as a meaningful, valuable, and goal-oriented activity. Thus, without rejecting the methodological progress of contemporary science, it remains a plausible option. Despite lingering problems with the methodological formulation, this article asserts that the Islamization of science is relevant as a theoretical response to the crisis of values ​​in the epistemology of modern science.

Islamic Religious Education (PAI) faces serious challenges from the crisis of integrity and trust in the digital era, which is manifested in the weakening of social solidarity (ukhuwah) and the emergence of a toxic social environment due to disinformation and fragility of commitment. This study aims to analyze and formulate an implementation model for the values ​​of Shiddiq (honesty and truth) and Amanah (trustworthiness and responsibility) in PAI, as well as to examine their role in building Ukhuwah and a Positive Social Environment among students. The method used is library research with a qualitative-analytical approach, involving a critical review of relevant scientific literature, journals, and books. The results of the study indicate that the implementation of these two prophetic values ​​must be carried out transformatively through integrated Project Based Learning (PjBL) and Problem Based Learning (PBL) methods, not merely cognitive transfer, but through real practice. The value of Shiddiq plays a central role in building trust and countering hoaxes, while Amanah ensures commitment and social responsibility, which collectively strengthen the bonds of ukhuwah. These findings imply the urgency of developing an Islamic Religious Education (PAI) curriculum that is responsive to digital ethics and strengthens teacher exemplary behavior (uswah hasanah) as a model of integrity. It is recommended that future research conduct empirical tests of the proposed implementation model to strengthen the generalizability of the findings.

The Problem-Based Learning (PBL) model is a teaching strategy that focuses on students being the main participants in their education by engaging in the resolution of actual problems. This article looks into how PBL is applied in the classroom, its effects on enhancing students' critical thinking abilities, and the primary attributes of this model that aid in developing problem-solving skills. PBL consists of five key phases: identifying a challenge, organizing research efforts, performing both individual and group inquiries, gathering and sharing findings, and reflecting on the process. These phases create a learning experience that promotes teamwork, self-directed research, and thorough analysis of information. Findings from this research reveal that PBL significantly enhances students' critical thinking skills, particularly in areas like analysis, assessment of evidence, solution formulation, and articulating arguments logically. Furthermore, features of PBL, which include prioritizing students, addressing real-world issues, fostering self-directed learning, encouraging group collaboration, and positioning the teacher as a guide, play a crucial role in enhancing problem-solving capabilities. By tackling issues that relate to their daily lives, PBL motivates students to independently build knowledge, foster innovation, and reinforce their autonomy in the learning journey.
