Comparison for Assessment of Pipeline Integrity with ASME B31.8 and ASME B31.G
Get PDFIntegrity assessment is a critical process in the oil and gas industry to prevent pipeline failures such as leaks or ruptures. This study evaluates a gas pipeline's integrity using two assessment methodologies: the conventional design code (ASME B31.8) and the defect-specific method (ASME B31G). An in-line inspection (ILI) conducted in June 2024 revealed the maximum corrosion depth with a depth-to-thickness ratio (d/t) of 0.35. The design code assessment classified the pipeline as potentially unsafe due to wall thickness falling below the minimum requirement. In contrast, the ASME B31G assessment showed the pipeline could safely withstand the design pressure. The comparison highlights the conservative nature of design codes and underscores the importance of defect-specific assessment in accurately determining residual life and optimizing maintenance strategies

With the target temperature of 25℃ in the common area, the system dynamically adjust the actuators to keep temperature within +/- 1C° range. Within the implementation, the energy usage on the AHU system itself can be lowered from 100% to65% - 73%
EFEK SKOR ESG PADA KAPITALISASI PASAR PERUSAHAAN DALAM INDEX ESG LEADERS INDONESIA
Get PDFESG is a concept that prioritizes sustainable development, investment, and company operations using three criteria—environmental, social, and governance. Businesses with strong ESG policies typically do better over the long run. Revenue, net profit, growth, and a greater market valuation—reflected in market capitalization—can all be indicators of improved long-term performance. This study examines the relationship between ESG scores and market capitalization for 17 businesses included in the Indonesian ESG Leaders Index (March 15-September 19, 2023) using firm value as an intervening variable. Multiple linear regression analysis was employed as the data analysis strategy. The study’s results, which were obtained by regression analysis with IBM SPSS 29, demonstrated that ESG scores had no discernible impact on market capitalization as measured by business value overall.

PENGETAHUAN GURU PUSAT KEGIATAN BELAJAR MASYARAKAT X MENGENAI PESERTA DIDIK BERKEBUTUHAN KHUSUS
Get PDFThe Community Learning Activity Centre (Pusat Kegiatan Belajar Masyarakat/PKBM) is a non-formal educational institution that provides a 12-year basic education equivalent. PKBM X in Jakarta has students with special educational needs. As an inclusive PKBM, teachers are expected to have knowledge about students with special educational needs (PDBK). Learning at PKBM X is reportedly suboptimal due to a lack of teacher knowledge about PDBK. Therefore, it is important to assess the basic knowledge that PKBM X teachers have about PDBK. The teacher knowledge measured in this study is based on knowledge and basic-level cognitive processes in Bloom's Taxonomy. This descriptive quantitative study involved 58 teachers from ten PKBM X branches in Indonesia. The measuring instrument is a questionnaire about teachers' knowledge. The results showed that 55.17% of teachers had insufficient knowledge, 31.03% had sufficient knowledge and just 13.79% had a good grasp of the subject. This insufficient knowledge was mainly related to strategies for handling PDBK, with an average score of 48.85%. The same applies to the application domain in Bloom's Taxonomy, where the average knowledge is 51.47%. It is suspected that the PKBM X teachers' lack of knowledge stems from inadequate training in PDBK
INTERGENERATIONAL INSIGHT OF FRAUD INTENTION IN DIGITAL BANKING: WHAT MAKES CUSTOMERS GO ROGUE?
Get PDFThis study investigates the factors influencing customers' intention to commit fraud in the context of mandatory digital banking, with a focus on intergenerational differences between Generation Y and Millennials. Guided by the Fraud Triangle Theory, the research explores how perceived opportunity, financial pressure, and rationalization contribute to fraud intention. A mixed-method approach was employed, beginning with in-depth qualitative interviews followed by a quantitative survey of 100 digital banking users in Indonesia. The constructions were validated through factor analysis, and the model was tested using Partial Least Squares (PLS-SEM). The findings reveal that perceived opportunity and rationalization significantly influence fraud intention, while financial pressure does not. Furthermore, generational differences do not moderate the relationships between the predictors and fraud intention. These results highlight the importance of improving digital system integrity and addressing ethical rationalizations to prevent fraud. The study contributes to a deeper understanding of consumer-initiated financial fraud in the digital age and suggests avenues for more targeted fraud prevention strategies
