Abstract

Phishing attacks represent a significant cybersecurity threat aimed at stealing sensitive user information through psychological manipulation using fake websites. Conventional detection methods relying on blacklists are considered ineffective in recognizing zero-day attacks or newly published phishing sites. This study aims to develop an automated detection model using a Machine Learning approach by comparing the performance of two Supervised Learning algorithms: K-Nearest Neighbor (K-NN) and Decision Tree. The dataset used is sourced from the UCI Machine Learning Repository, consisting of 11,055 records with 30 URL characteristic features. Performance evaluation was conducted using Accuracy metrics and Confusion Matrix analysis. Experimental results indicate that the Decision Tree algorithm significantly outperforms K-NN with an accuracy of 95.21%, while K-NN achieved an accuracy of only 60.11%. Furthermore, Decision Tree demonstrated a very low False Negative rate, making it a more recommended model for real-time cybersecurity system implementation.

Abstract

Pengembangan aplikasi lelang hasil laut untuk nelayan bertujuan untuk menyelesaikan permaslaahan DUDI dalam pelaksanaan operasional usahanya dalam mengekspor hasil laut ke berbagai negara. Penelitian ini dilakukan di kepulauan riau, dikarenakan hampir 96 % dari wilayah kepulauan riau merupakan perairan. Peranan nelayan bagi perekonomian masyarakat pesisir merupakan roda bagi perputaran ekonomi masyarakat. Keterbatasan akan akses untuk memperluas kegiatannya menjadi faktor utama yang membuat produk-produk mereka sulit untuk dikenal di luar Kepualuan Riau. Akses yang dimaksud adalah wadah yang mampu membantu masyarakat pesisir untuk belajar dan memfasilitasi masyarakat untuk memperbaiki kualitas produk agar layak untuk di ekspor. Hasil yang diperoleh dalam pelaksanaan kegiatan ini berupa Aplikasi Ekspor Pedia berbasis android dan IOS, MoU antara perguruan tinggi dan Mitra, Pembentukan inkubator Bisnis, downloader, HKI merek dan Cipta, terdapat banyak kendala dalam pelaksanaan kegiatan diantaranya sulit dalam mencari informasi dasar pelaksanaan program diakibatkan oleh lokasi yang dituju berada di luar pulau Batam, selain itu terdapat beberapa kendala terkait waktu pelaksanaan program yang singkat, dan masalah SDM yang belum maksimal. Dengan adanya program ini tidak hanya DUDI, masyarakat juga mendapat manfaat langsung dalam hal peluang mengembangkan usahanya.

Abstract

Female workers in the manufacturing sector in Batam City often face challenges in financial planning, particularly regarding pension funds. Lack of knowledge and information about the importance of pension funds, coupled with limited awareness campaigns, result in many workers not participating in pension programs. Additionally, a work culture focused on short-term targets often leads female workers in this sector to view long-term financial planning, such as retirement, as less important. This study aims to investigate and analyze the partial and simultaneous effects of framing effect, mental accounting, and financial decisions on the effectiveness of pension funds among female workers in manufacturing companies in Batam City. This study employs causal associative research, and the research method used is quantitative. The population in this study consists of all female workers in manufacturing companies in Batam City, whose exact number is unknown. Four manufacturing companies were randomly selected, and 50 respondents were selected from each company. The sampling method used non-probability sampling with purposive sampling techniques, with several criteria including women aged 40-50 years with a minimum of 1 year of work experience and companies employing more than 250 workers. The sample size for this study was 200 respondents. The data were analyzed using SPSS version 25. The results of the study indicate that the framing effect partially influences the effectiveness of pension funds, mental accounting partially influences the effectiveness of pension funds, financial decisions partially influence the effectiveness of pension funds, and the framing effect, mental accounting, and financial decisions simultaneously influence the effectiveness of pension funds. The adjusted R-squared value of 0.728 can be referred to as the coefficient of determination, This means that 0.741 (74.1%) of the effectiveness of pension funds can be obtained and explained by the framing effect, mental accounting, and financial decisions, while the remaining 25.3% (100% - 74.1% = 25.3%) is explained by variables outside the model that were not studied.

Abstract

This qualitative study investigates how Fear of Missing Out (FOMO) influences Generation Z investment behavior and emotional bias in financial decision-making processes. The research employed an interpretive phenomenological approach with in-depth semi-structured interviews conducted among Generation Z investors in Indonesia to understand the psychological mechanisms underlying FOMO-driven investment decisions. Systematic thematic analysis revealed three primary themes: FOMO as an emotional investment driver, social media influence creating information asymmetry, and financial literacy functioning as a complex moderating factor. The findings demonstrate that FOMO operates as a powerful emotional compulsion that systematically overrides rational decision-making processes, with social media exposure to peers' investment success serving as the most potent trigger for impulsive investment behavior. A significant "information paradox" emerged where participants heavily rely on low-credibility sources such as financial influencers while underutilizing high-credibility alternatives like official company reports, prioritizing accessibility over accuracy. The relationship between financial literacy and FOMO vulnerability proved non-linear, with medium literacy levels paradoxically increasing overconfidence bias while high literacy enabled sophisticated rationalization of emotional decisions. These findings contribute to behavioral finance theory by revealing how digital-social contexts amplify emotional biases beyond traditional market psychology models, suggesting that conventional financial education approaches may be insufficient for addressing emotionally-driven decision-making among digital-native generations.

Abstract

This study investigates the influence of present bias and overconfidence on consumer debt decision-making among manufacturing workers in Batam, Indonesia, incorporating financial literacy as a moderating variable. Batam, a strategic free trade zone and major industrial hub, faces a growing phenomenon of consumer over-indebtedness fueled by the rapid expansion of digital lending platforms and online loans among its workforce. A quantitative cross-sectional survey design was employed, with a sample of 215 manufacturing workers drawn from Batam’s major industrial estates through purposive sampling. Data were collected via validated Likert-scale questionnaires and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4.0. The findings reveal that: (1) present bias exerts the strongest positive and significant effect on consumer debt decisions (β = 0.387; p < 0.001); (2) overconfidence positively and significantly affects consumer debt decisions (β = 0.294; p < 0.001); (3) financial literacy significantly weakens the relationship between present bias and consumer debt decisions (β = –0.168; p < 0.01); however, (4) financial literacy does not significantly moderate the relationship between overconfidence and consumer debt decisions (β = –0.074; p > 0.05). These findings reveal an asymmetric moderation effect, indicating that conventional financial education is effective in mitigating present bias but insufficient in reducing overconfidence, which requires fundamentally different intervention approaches targeting metacognition rather than knowledge acquisition. The study contributes to behavioral finance literature by extending the application of hyperbolic discounting and overconfidence theories to consumer debt contexts in developing-country industrial zones and offers practical implications for financial regulators and corporate financial wellness programs.
THE EFFECT OF TAX AWARENESS AND PERCEIVED EQUITY ON TAX COMPLIANCE OF DIGITAL ECONOMY ACTORS IN BATAM: THE MODERATING ROLE OF VAT ON ELECTRONIC TRANSACTION (PPN PMSE) COLLECTION POLICY Faris Ramadhan; Etty Sri Wahyuni; Mercy Reyne Marlina Tirayoh; Benni Sumarman; Basri

Abstract

The rapid expansion of Indonesia’s digital economy demands a strengthened digital taxation framework. This study examines the effect of tax awareness and perceived equity on tax compliance among digital economy actors in Batam, Indonesia’s largest Free Trade Zone (FTZ), with the Value Added Tax on Electronically Traded Transactions (PPN PMSE) collection policy serving as a moderating variable. Using a quantitative cross-sectional survey, data were collected from 198 digital economy actors across Batam’s major e-commerce ecosystems through validated Likert-scale questionnaires and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4.0. The findings reveal that: (1) tax awareness exerts the strongest positive and significant effect on tax compliance (β = 0.412; p < 0.001; f² = 0.224); (2) perceived equity positively and significantly affects tax compliance (β = 0.318; p < 0.001; f² = 0.138); (3) the PPN PMSE collection policy positively and significantly moderates the tax awareness–compliance relationship (β = 0.147; p < 0.01); however, (4) the PPN PMSE collection policy does not significantly moderate the perceived equity–compliance relationship (β = 0.063; p > 0.05). These findings reveal an asymmetric moderation effect: platform-based VAT collection functions as a behavioral nudge that amplifies tax awareness effects but is structurally incapable of correcting deeply rooted perceptions of tax inequity—particularly the perceived unfairness between FTZ-based and non-FTZ digital sellers, and between digital and conventional businesses. The study contributes to digital taxation literature by integrating the Slippery Slope Framework with Nudge Theory, empirically demonstrating the conditional and asymmetric moderating capacity of third-party collection mechanisms, and identifying a novel “spatial equity” dimension relevant to free trade zone taxation. Practical implications are offered for Indonesia’s Coretax administration reform and the design of differentiated compliance strategies.
