In the rapidly advancing digital era, information security has become a crucial aspect in maintaining the confidentiality, integrity, and authenticity of data. This article discusses the relationship between information system auditing and the use of modern cryptographic combinations in securing text messages. Information system auditing serves as an evaluation mechanism to ensure that security policies, procedures, and standards are correctly and consistently applied. On the other hand, modern cryptography provides advanced encryption technology that protects text messages from unauthorized access and manipulation. By combining these two approaches, we can create a robust framework for securing text messages, ensuring that data remains safe and protected during transmission and storage. Research results indicate that integrating information system auditing with modern cryptographic techniques significantly enhances the security and reliability of information systems.

The use of automation systems is needed in sorting, one of which is the sorting of objects based on the size of the object being sorted. Especially in the sorting process, there are still many industries that use conveyors that only function for one product with the same weight characteristics. Therefore, to sort the same goods with different weights, a separate conveyor is needed so that many conveyors are used. The development of a sorting machine is an important aspect in the modern automation and manufacturing industry. This research aims to design and analyze the static loading of the sorting machine frame using SOLIDWORKS software. The design method used includes detailed 3D modeling of the machine frame by considering the strength, stability and reliability of the structure. The simulation results using SOLIDWORKS software show the stress (von Mises) with a maximum value of 82.26 MPa, while the theoretical calculation result is 84 MPa. Displacement with a maximum value of 4.063 mm, while the theoretical calculation result is 1.60 mm. The safety factor is 2.38, while the theoretical calculation result is 2.43. The difference between manual calculation and simulation is 0.02% for von Mises stress, 1.5% for displacement, and 0.02% for safety factor.

In order to achieve production targets for fuel and petrochemical products to support national energy security, reliable equipment is needed to support the operation of petroleum processing refineries. Main equipment such as injection pumps must be able to adapt to the expected operational conditions. Check valve is one of the supporting components of injection pump reliability. Research was conducted to determine the velocity characteristics of two ball type check valve designs using Computational Fluid Dynamics (CFD) numerical simulations. In this research, three variations of pump stroke length were simulated, namely 25%, 50% and 100% with three variations of solid particle size, namely 200, 250 and 300 microns. The fluid that passes through the check valve is a solid-liquid mixture of catalyst and particles. The analysis carried out is by comparing the velocity values as well as the flow patterns produced for each variations used. The simulation results show that of all the variations tested, the model with a stroke length of 100% produces the maximum velocity. In addition, the size of solid particles is inversely proportional to fluid velocity and flow. From the results of this research, it was also found that model 2 has more potential for backflow towards suction, and also model 2 has more potential for clogging because particles that should flow stop inside the check valve.

Data transmission efficiency is crucial in wireless sensor networks (WSNs), where limited battery life and signal reliability are significant concerns. This research explores various machine learning algorithms aimed at optimizing data transmission in WSNs, focusing on reducing energy consumption and enhancing network stability.

Digital transformation in the public transportation sector is part of the national development priority agenda aimed at improving service quality and operational efficiency. This study aims to analyze the implementation of cashless payment-based digital transformation in public transportation policy on the Suroboyo Bus in Surabaya, analyze service quality based on SERVQUAL dimensions, identify supporting and inhibiting factors for implementation, and evaluate the success and shortcomings of the policy. This research uses a qualitative approach with a descriptive research type. The results show that the implementation of cashless payment on the Suroboyo Bus has been running well since 2018, with four main payment methods: QRIS, e-money cards, plastic waste contributions, and the Child Identity Card (KIA). QRIS has become the dominant payment method with a 48% share in 2025. Service quality based on SERVQUAL dimensions shows good results in the aspects of tangibles, reliability, and responsiveness, but still requires improvement in the dimensions of assurance and empathy. Supporting factors for implementation include government commitment, the availability of regulations (Perwali No. 22 of 2023)., adequate infrastructure, and support from digital payment service providers. Inhibiting factors include limited digital literacy, internet network disruptions, limited economic access, and lack of socialization. The success of the policy is reflected in increased operational efficiency, financial transparency, and a rise in the number of users from 1.2 million (2019). to 3.5 million (2025). Shortcomings of the policy include the digital gap for vulnerable groups, dependence on internet networks, and a decrease in participation in the plastic waste payment program from 25% (2023). to 12% (2025).

The quality of audits is a crucial measurement to determine how effectively an audit has been conducted and the extent to which it produces relevant, accurate, and reliable information. High-quality audit outcomes are typically assessed based on how well the audit team performs the planning process, ensures that the audit plan is relevant and effective, produces audit reports that meet stakeholders' needs, and adheres to ethical principles aligned with established auditing standards. This study aims to evaluate the extent to which several key factors—namely audit planning, audit implementation, audit reporting, and ethical principles—have a direct impact on the audit quality of the Government Internal Supervisory Apparatus (Aparat Pengawasan Intern Pemerintah, or APIP) in the Binjai City Government. The research employs a quantitative approach, utilizing primary data collected from a sample of 39 government auditors. Data analysis was performed using the SmartPLS (Partial Least Squares) application, which allows for the modeling of complex relationships between variables. The findings reveal that audit planning, audit implementation, and audit reporting all have a significant and direct influence on the quality of audit results. These components play a central role in enhancing the credibility, effectiveness, and usefulness of internal government audits. However, the study also finds that ethical principles, while essential in guiding professional conduct, do not have a statistically significant direct impact on audit quality in this specific context. The results underscore the importance of strengthening technical aspects of the audit process, such as planning and reporting, while also maintaining strong ethical foundations as complementary rather than primary determinants of audit quality. This research contributes to the ongoing efforts to improve the effectiveness and reliability of internal government audits in Indonesian public sector institutions.

Nowadays, many brands, be it in the field of beauty or others, utilize influencer marketing as one of the promotional strategies to market their products.
