Abstract

The rapid expansion of industrial internet of things (IIoT) adoption in Industry 4.0 has improved automation and real-time control yet simultaneously increased security risks in operational technology (OT) environments, where device integrity and system reliability are critical. Existing attestation approaches such as SAFEHIVE, SEDA, CRA, and ERASMUS provide scalable verification capabilities but still lack continuous hardware-rooted validation and adaptive access control required for real-time industrial systems. To address this gap, this study proposes a hybrid cybersecurity framework that integrates IoT device-trusted remote attestation (ID-TRA) based on trusted platform module (TPM) with zero trust architecture (ZTA) to ensure continuous device trustworthiness in brewery operations. The framework was implemented on an industrial testbed with programmable logic controllers (PLCs), edge devices, and industrial switches, and it was evaluated through measurements of attestation latency, false positive rate, communication overhead, and TPM resource utilization. Experimental results show that the framework achieves an average attestation latency of 250 ms, a false positive rate below 2%, and a communication overhead of only 1.1%, while TPM resource usage remains within acceptable bounds (62% CPU and 48 MB RAM). These outcomes demonstrate that the proposed solution can reliably detect unauthorized firmware modifications, prevent compromised devices from accessing critical network zones, and maintain compatibility with real-time control processes. Overall, the integration of ID-TRA and ZTA enhances device-level assurance and strengthens industrial cybersecurity resilience against firmware tampering, replay attacks, and unauthorized lateral movement.

Abstract

This study aims to improve conceptual understanding by implementing the Discovery Learning model assisted by digital interactive media and its impact on improving the understanding of the concept of the Unitary State of the Republic of Indonesia (NKRI) in class VII A students of SMPN 12 Malang. This study is a Classroom Action Research (CAR) which was carried out in two cycles in May 2026. Data collection techniques used include: (1) a post-test at the end of each cycle to measure students' cognitive understanding, and (2) structured observation of the learning process to document student activities during the action. Post-test data were analyzed using N-Gain scores and classical completion percentages, while observation data were analyzed quantitatively based on activeness, cooperation, and self-confidence. The results showed a gradual increase in class average scores from pre-cycle to cycle I and cycle II, with classical completion exceeding the target of 75% of students who met the KKM 75. Observations of the learning process showed an increase in the consistency of student activeness between cycles. These findings confirm that the application of the Discovery Learning model assisted by digital interactive media is effective in improving the conceptual understanding of the material on the Unitary State of the Republic of Indonesia (NKRI) in junior high school students.

Abstract

System frequent Linux operations are used on critical systems. Part systems big pay attention to safety and reliability. Ubuntu Linux is one of all Lots common Linux distributions used for system server operation. To improve security on Ubuntu Linux is required to strengthen the security system process. Strengthening security system operation is one solution for the system operation more stand to attacks and vulnerabilities. Center for Internet Security (CIS) is one caring organization for cyber security and provides benchmarks for configuration system safe Ubuntu operation. Benchmarks cover recommended settings for various component systems like file permissions, application, configuration networking, logging, and management of users. The study aims to improve security system operation with the use of control strengthening security based on CIS Benchmark v1.1.0 servers’ level 2 with the automatic model use packers application. The developed methodology consists of four phases. The first phase is Packer server installation and configuration. The second phase is to build a configuration base Ubuntu installation with user data. The third phase is the application Ansible playbook in runtime Packer automation for automation reinforcement at the time of installation and produces image virtual machine. In phase, lastly, apply structure using image virtual machine-generated and verified percentage reinforcement and optimization achieved. After strengthening security, use research methods. This generated a score conformity audit of 218 controls or 99.54% of the total 219 CIS Benchmark controls.

Abstract

Certification Government Procurement of Goods/Services has applied since 2008 and switched to certification-based computers in 2015. However, technology information has raised problems with the security of necessary information fixed, like illegal access and practice jockeying through access remotely against application exam-based computers. To overcome the challenge, a framework Works security comprehensive information is required. In a study, the researcher compares System Certification Quality Management with Standard ISO 27001:2022 and observes Suite implementation certification procurement to develop a framework special can implement in system certification. Analysis results show that LKPP requires framework Work security information on the system certification procurement goods/services government based on the ISO 27001: 2022 standard. The proposed framework aims to facilitate application Certification Procurement by LKPP as institution-maker regulation and implementation system certification procurement.

Abstract

The data and information management process at BMKG entails certain risks related to information security incidents. There needs to be more emphasis on addressing these incidents regarding policies, procedures, technology, and human resources. This research project aims to develop an incident management system by ISO 27035 standards. Qualitative research methods have been employed for BMKG Communication Network Center case studies. The approach involves aligning information security incident management with BMKG's business processes. The outcome of this research includes creating policies, documents, and standardized procedures designed to enhance BMKG's capabilities in effectively managing and mitigating incident threats.
