This study examines the crucial role of political ethics in anti-corruption efforts in Indonesia, focusing on Pancasila as the moral and philosophical foundation (Nasoha et al., 2024; Atqiya & Nasoha, 2024). Through a qualitative literature review, the research reveals that weaknesses in political ethics significantly contribute to corrupt practices among elites and state institutions. The study highlights that corruption often stems from a lack of adherence to ethical standards within the political system. Therefore, strengthening political ethics is essential to preventing corruption. The principles of justice, accountability, and public responsibility are critical to this effort, ensuring that government actions align with ethical values. Pancasila’s core values, especially social justice and gotong royong (mutual cooperation), provide a solid moral framework for fostering a transparent, fair, and integrated government system. By embedding these values into political practice, Indonesia can strengthen its anti-corruption efforts, improve public trust, and promote a more just and accountable political environment.

Qanun of Banda Aceh City Number 4 of 2022 emphasizes that the Tirta Daroy Regional Public Company of Drinking Water aims to provide fair and sustainable drinking water services. The legal relationship between the customer and the company is regulated through the Decree of the Board of Directors PEG Number. III/10/PDAM/2020. However, there are still many customers who are in default in the form of late payments that cause losses to the company and are contrary to Article 1243 of the Civil Code regarding the obligation of debtors to compensate for losses due to negligence. This study aims to analyze the default settings in the customer connection agreement at  the Tirta Taroy Regional Public Drinking Water Company  , identify the factors causing defaults, and explain the form of applying civil sanctions to customers who commit defaults. This study uses an empirical juridical method with qualitative descriptive analysis based on legal and field data. The results of the study show that the most dominant forms of default in customers of the Tirta Daroy Regional Drinking Water Public Company are late and arrears of payments, not paying at all and misuse of water connections. The main causative factors include economic conditions, administrative negligence, and intentional elements. Legally, this default causes financial losses and disrupts the sustainability of public services. Sanctions are applied in stages through notices, warnings, summonses, to fines, compensation, or disconnection. The Tirta Daroy Regional Public Company is advised to follow up on customer complaints, improve the billing system, adjust the sanction clause proportionately, and increase legal awareness through socialization.

This study aims to describe the characteristics of SMK Al-Azami students in emulating the morals of the Prophet Muhammad (peace be upon him) as part of character development based on Islamic values within vocational education. The background of this research lies in the urgency of character education that not only emphasizes academic competence and technical skills but also focuses on moral formation and professional ethics. This research employed a qualitative approach using a library research method by analyzing relevant classical and modern Islamic literature, supported by documentation of school activities. The results reveal that the moral values of the Prophet Muhammad have been well internalized in students’ daily behavior, which includes four core dimensions: Shidq (honesty), Amanah (trustworthiness), Istiqamah (discipline), and Rahmah (compassion). The value of Shidq is reflected in students’ honesty during vocational practice and in reporting work results; Amanah is demonstrated through responsibility for tools and group tasks; Istiqamah appears in punctuality, consistency, and work discipline; and Rahmah is shown through respectful, empathetic, and cooperative social interactions. The findings indicate that Islamic character education effectively shapes students with integrity, discipline, and social awareness, serving as a model for moral development in vocational schools. Furthermore, this research highlights the importance of strengthening teacher exemplarity, religious habituation, and curriculum integration of Islamic moral values in vocational learning to ensure sustainable character development.

This study employs a qualitative approach through interviews with PAI teachers, observations of student activities, and documentation related to school-based environmental programs. The findings reveal that Islamic teachings on cleanliness, environmental balance, and human responsibility as stewards of the earth provide a strong foundation for encouraging students to protect the environment through positive habits such as proper waste disposal, wise use of resources, and participation in greening activities. Nevertheless, the implementation still faces several challenges, including inconsistent student discipline and limited supporting facilities within the school. Overall, PAI serves as an educational medium capable of shaping ecological behavior when supported by strong collaboration between schools, teachers, and families.

This study aims to analyze the differences in thermal conditions between coastal and riverside settlements, focusing on variations in temperature, humidity, and wind speed during day and night. The research sites include the coastal area of Dusun Karama Tengah (seaside) and Desa Salotengnga (riverside). Measurements indicate that the coastal area experiences more extreme daytime temperature fluctuations, reaching nearly 39 °C, with nighttime temperatures remaining warm and showing noticeable variation among points. In contrast, the riverside area displays more stable temperature patterns, with nighttime temperatures ranging between 28–30 °C. Relative humidity along the coast increases consistently at night, whereas in the riverside area it is heterogeneous, varying from saturated to very dry conditions. Wind speed serves as a key differentiating factor: the coastal area is still influenced by land–sea breezes, while the riverside environment tends to be stagnant with weak natural ventilation. These findings highlight distinct thermal comfort challenges in both settings—coastal areas are prone to daytime heat stress, whereas riverside areas face nighttime discomfort due to humidity and air stagnation. The results provide a foundation for adaptive architectural and spatial design strategies responsive to local microclimatic contexts.  

Bullying is one of the most common forms of violence still occurring in schools, causing serious impacts on students’ psychological conditions and social development. Various efforts have been made to reduce bullying cases, yet communicative campaign media that match the characteristics of the digital generation remain limited. This study aims to develop educational media based on interactive motion graphics designed with Visual Communication Design principles to support anti-bullying digital campaigns in schools. The research stages include designing the main characters using Adobe Illustrator and Adobe Photoshop, separating body parts in vector format for easier animation, importing the files into Adobe Character Animator, and synchronizing movements, facial expressions, and voices through dubbing processes. The final product is an interactive animation entitled “Berani Bicara, Berani Membela” (Dare to Speak, Dare to Defend), which features three main scenes: bullying in a school corridor, peer support in the classroom, and reporting the case to the guidance counselor. The findings indicate that this media provides a more engaging and interactive learning experience while effectively delivering moral messages. The animation not only emphasizes the importance of victims’ courage to report bullying but also highlights peer support and the school’s role in providing protection. Therefore, interactive motion graphics can serve as an alternative digital campaign strategy that is relevant, easily accepted by young generations, and has the potential to foster safe, inclusive, and friendly school environments for all students.

The rapid growth of social media as a primary channel for information dissemination has triggered a significant surge in the distribution of hoaxes, potentially damaging social order, instigating mass disinformation, and threatening national security. This research aims to design an intelligent algorithm for hoax detection by integrating a critical thinking approach into Natural Language Processing (NLP)-based text processing. The algorithmic model is built using a combination of linguistic features, argument logic, and cognitive indicators such as the detection of unsubstantiated claims, identification of source bias, and evidence testing. To ensure accountability and transparency of the system, an Explainable AI (XAI) approach is applied so that classification results can be understood by non-technical users. The research results show that integrating critical thinking significantly improves detection accuracy to 93.1%, with an increase in precision and recall for detecting hoaxes based on emotional narratives. Beyond technical aspects, this model aligns with the mandate of Law of the Republic of Indonesia Number 11 of 2008 concerning Information and Electronic Transactions (ITE Law), particularly Article 28 paragraph (1), which prohibits the dissemination of false and misleading news that harms the public. Therefore, this system is not only scientifically relevant but also supports law enforcement and strengthens digital literacy in the post-truth era. These findings are expected to be a strategic contribution to the development of an ethical, critical, and responsible digital ecosystem.

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.

In today’s era, we are very familiar with operating systems that function to manage the work of hardware and software so they can be used properly. One of the most widely used operating systems is Windows, because it has an easy-to-understand interface and is capable of running multiple applications simultaneously. To support this, Windows requires a process management mechanism, namely a way for the system to organize running programs so they do not interfere with each other and remain stable. In process management, there is an important component called the Process Control Block (PCB). The PCB can be likened to an identity card or a complete record of a process, as it contains information such as the process ID, status, CPU usage, memory, and files being used. This study aims to analyze the role of the process control block, focusing on how the Process Control Block stores important information regarding the status and activity of each process, ensuring smooth, efficient, and non-conflicting application execution. In this research, experiments were conducted to measure CPU usage, memory, and execution time by various processes with different priorities to observe the information of running processes. The analysis results show that each application has its own Process ID and PCB, which records status, CPU registers, memory allocation, and I/O resources used. The PCB enables multiple applications to perform multitasking effectively.

This study originated from the issue of students’ limited comprehension of healthy and nutritious food concepts, which influences their lack of awareness in practicing a balanced diet in daily life. The conventional learning approach with minimal integration of visual aids has made students less engaged and hindered their overall understanding of the material. The primary objective of this research is to enhance fourth-grade students’ understanding of healthy and nutritious food at MI Al-Barokah through the application of picture-based learning media. Planing, implementation, observation, and reflection were the two stages of Classroom Action Research (CAR) that was used in the research. The participants were 25 fourth-grade students of MI Al-Barokah. Data were gathered through observations, interviews, and achievement tests, and analyzed using both qualitative and quantitative descriptive methods. The findings revealed a marked improvement in students’ understanding after the introduction of picture media, as reflected in the increasing average learning scores across cycles, along with greater motivation, participation, and engagement in classroom activities. The integration of picture media proved effective in facilitating a clearer, more engaging, and meaningful grasp of healthy and nutritious food concepts. These results suggest that picture-based instructional media can serve as a valuable strategy to improve the quality of thematic learning in elementary education, especially in lessons concerning healthy living and balanced nutrition.

This study aims to examine the effect of using the Survey, Question, Read, Recite, Review (SQ3R) method assisted by digital story texts on students' critical thinking skills in the material "Book of the Window World" of grade V of SD Negeri 104202 Bandar Setia. The background of this study is based on the low critical thinking skills of students due to the dominance of conventional methods that are less varied and minimal use of learning media, especially in Indonesian subjects. This study uses a quantitative approach with a quasi-experimental method and a Nonrandomized Pretest-Posttest Control Group Design. The research subjects consisted of class VA (experimental, n = 22) who received learning with the SQ3R method assisted by digital story texts, and class VB (control, n = 23) who received conventional learning. The pretest results showed that students' initial critical thinking skills were in the moderate category (experimental x ̄ = 67.23; control x ̄ = 51.96). After the treatment, the experimental class' posttest average increased significantly to 82.41, or 15.18 points, while the control class did not experience any significant improvement. A t-test demonstrated a significant difference between the two groups (t count > t table). The study's conclusions indicate that the SQ3R method, aided by digital narrative texts, significantly improved students' critical thinking skills compared to conventional methods.
