Introduction The increasing digitalization of financial services has made cybersecurity and regulatory compliance key operational challenges for banking institutions in Indonesia.
According to data from the Financial Services Authority (OJK), there has been a significant increase in customer data breaches and phishing attacks targeting digital banking platforms.
Users aged 30Ae55, who have a significant mobile app usage, exhibit a worrying trend of vulnerability to online fraud.
The primary sources of risk are outdated security frameworks and low user awareness, both of which contribute to substantial financial losses.
According to a World Bank report (World Bank, 2.
, failure to comply with global data security standards can result in fines of up to 4% of a financial institution's annual revenue.
Furthermore, the National Information Security Survey (SKIN) conducted by the National Cyber and Crypto Agency (BSSN, 2.
estimates that more than 80% of active banking institutions in Indonesia do not fully comply with international cybersecurity standards, and approximately 15% of them report unresolved critical This escalation in cyber threats raises serious concerns about the stability of the financial system and customer trust.
Based on these data, the author intends to analyze the relationship between the level of company investment in cybersecurity technology and the level of data regulation compliance (GDPR/ISO 27.
in digital banks in Jakarta.
Methods This study adopted an observational, correlational analytical research design with a limited longitudinal approach aimed at assessing the relationship between academic self-efficacy and the intensity of learning procrastination among Distance Education (PJJ) students.
The study was conducted at the virtual campus of Universitas Cendekia Nusantara, covering all regions of Indonesia, over two academic semesters (August 2024 to June 2.
Subjects included all active thirdyear students in the Distance Education (PJJ) study program who met the inclusion criteria: full-time enrollment, accessing the online learning platform at least three times a week, completing the self-administered questionnaire, and providing written consent to participate.
Students who were on leave, taking fewer courses than the minimum credit limit, experiencing prolonged technical problems during the study, or refusing to participate were excluded from the study group.
The sampling technique used was multistage cluster sampling.
The minimum sample size was calculated using the G*Power formula for correlation analysis, assuming a medium effect size .
= 0.
, a significance level 05, and a statistical power of 0.
This resulted in a minimum sample size of 84 participants.
After accounting for the potential 15% attrition rate common in distance learning studies, the minimum sample size was 97 students.
The primary independent variable in this study was academic self-efficacy, while the dependent variable was students' level of learning procrastination.
Data were collected using two validated questionnaires: the "General Self-Efficacy Scale" adapted for the academic context and the "Procrastination Assessment Scale for Students" (PASS).
These instruments measure demographic characteristics, selfefficacy, and procrastination.
Academic self-efficacy was measured using an interval scale .

Therefore, it can be statistically concluded that there is a significant and strong relationship between the level of property tax discount implementation and real estate investment interest among Discussion This research was conducted to evaluate the impact of property tax discounts on investment interest among millennial investors in Jakarta's Central Business District.
The study involved 115 respondents who met all study criteria.
Based on the research findings in Table 2, it can be seen that the majority of investors in the area perceive the tax discount policy as high .

2%), while 17 respondents .
8%) fall into the low perceived discount category.
These results are consistent with research conducted by Hadiwinata in 2023, which categorized fiscal incentives into three levels .
igh, medium, and lo.
The study found that 90% of respondents expressed a high perception of government incentives, particularly in the housing sector.
However, this finding differs from research conducted by Budiarto.
, in 2022, which divided incentives into effective, moderately effective, and ineffective categories.
Budiarto's research found that the majority of respondents actually considered fiscal incentives ineffective .

This study aligns with research conducted by Taufik et al.
in 2024, which divided investment interest into two categories: high and low, with the results showing that 70% of novice investors showed a strong interest in investing in property assets.
Based on Table 4, which examines the relationship between property tax discounts and investment interest, 98 respondents rated the tax discount as high, dominated by 85 respondents with high investment interest.
The Simple Linear Regression test showed a P-Value of $0.
000 and an R2 of $0.
Therefore, it is concluded that there is a strong relationship between the level of property tax discounts and real estate investment interest among millennials.
This finding is consistent with research by Taufik et al.
in 2024, which also stated a significant relationship between pro-investor fiscal policies and increased property investment volume.
Conclusion In general, the research results show that most students have a good understanding of cigarettes, including the harmful ingredients they contain and the health risks that can arise from smoking.
This indicates that students have received a significant amount of information about the dangers of smoking through various sources, including schools, families, and the media.
A high level of student knowledge reflects ongoing health education efforts, particularly regarding smoking prevention among adolescents.
Adequate understanding of the impact of smoking on the lungs, heart, and other organs is expected to foster a negative attitude toward Therefore, knowledge is a crucial factor in building students' awareness of maintaining health from an early age.
However, research also indicates that some students still engage in smoking.
This finding indicates that good knowledge is not completely capable of preventing students from trying or engaging in smoking Other factors beyond knowledge, such as peer influence, social environment, curiosity, and access to cigarettes, may also play a role in encouraging this behavior.
