Validation of the Cybersecurity Scale (CS-S) in the Industrial Context of Batam as an Initial Step Toward Assessing Zero Trust Architecture Adoption Readiness
This study aims to validate the Cybersecurity Scale (CS-S) as a measurement instrument for assessing human resource (HR) readiness in adopting the Zero Trust Architecture (ZTA) within Batam’s industrial context. The validation focuses on the human dimension—such as authentication awareness, access control, and data management—as a fundamental pillar in comprehensive ZTA readiness assessment. Using a quantitative approach, data were collected from 391 respondents representing multiple organizational levels in Batam’s manufacturing and logistics sectors. Confirmatory Factor Analysis (CFA) confirmed that the six-factor CS-S model (Confidentiality, Integrity, Availability, Control/Possession, Authenticity, and Utility) demonstrated excellent model fit (CFI = 0.980; TLI = 0.977; RMSEA = 0.051) and strong reliability (Cronbach’s Alpha 0.913–0.946). The findings revealed that Authenticity and Control/Possession had the highest factor loadings, emphasizing respondents’ awareness of identity verification and data ownership—two critical components of ZTA’s Identity and Access Management pillar. Meanwhile, Confidentiality, Integrity, and Availability reflected strong technical readiness among Batam-based firms. The study highlights that human readiness is a foundational element in successful ZTA adoption and that the validated CS-S serves as an essential tool for evaluating national cybersecurity readiness amid the enforcement of Indonesia’s Personal Data Protection Law (PDP Law).

The findings indicate that the areas with the highest levels of pollution overlap with violations of the core objectives of Islamic law, particularly the protection of life and intellect. This study emphasizes the urgency of integrating science and Islamic values as a conceptual and practical foundation for developing public policies that are ecologically just and spiritually grounded
Belajar Matematika dalam Perspektif Islam
No full textThis study examines the importance of learning mathematics from an Islamic perspective, arguing thatthis discipline is not only a cognitive tool, but also a spiritual means of understanding the greatness ofAllah SWT. In Islam, mathematics has a unique position as the Qur’an implicitly refers to order, balanceand careful calculation in the creation of the universe, as seen in the movement of celestial bodies or thedivision of inheritance. Hadiths of the Prophet Muhammad also encourage the pursuit of knowledge andthe use of reason, which broadly includes the study of mathematics as a foundation for the advancementof science. Through the library research method, the researcher collected and analyzed various literaturesources, including journal articles, academic books, books of tafsir, and Hadith, both in digital and printformats. To ensure validity and depth of analysis, the researcher applied data triangulation, comparing andconfirming findings from various sources. The results of the analysis show that learning mathematics canfoster tafakur (contemplation) and tadabbur (deep appreciation) of Allah’s creation, thus increasing faith andpiety. The study concludes that mathematics, from an Islamic perspective, is a way to uncover the secrets ofthe universe and witness the signs of divine power, making it a worshipful activity with a spiritual dimension
Analysis of Rock Magnetic Susceptibility in a Local Fault Zone at Sangkrek, Kulon Progo Regency
No full textThis study aims to analyze the pattern of magnetic anomaly distribution and determine the rock magnetic susceptibility values as a basis for identifying a local fault zone in the Dusun Sangkrek area, Kokap District, Kulon Progo Regency. The geomagnetic method was employed, with data acquisition conducted at 60 observation points using a Proton Precession Magnetometer (PPM) G-856 at 100-meter intervals. The total magnetic field data were corrected for daily variations and the International Geomagnetic Reference Field (IGRF) to obtain the total magnetic anomaly (ΔT). The magnetic anomaly values range from –3,1 × 10² nT to 6,8 × 10² nT, where high anomalies are dominant in the northern part, composed mainly of andesitic rocks, while low anomalies are found in the western and southern parts, corresponding to the Sentolo and Alluvium Formations. Data processing stages include reduction to the pole (RTP), upward continuation, and two-dimensional (2D) modeling to characterize subsurface magnetic variations. The modeling results indicate that the magnetic susceptibility of rocks varies between 1,0 × 10⁻⁴ and 1,1 × 10⁻¹ SI, with higher values associated with andesite and brecciated andesite, and lower values corresponding to siltstone, claystone, and sandstone. The contrasting distribution of susceptibility along several profiles reveals sharp lithological changes, interpreted as indications of a local fault zone that influences the subsurface magnetic distribution
