Abstract

The rapid digital transformation of Indonesian MSMEs has increased exposure to cyber threats such as phishing, malware, ransomware, and DDoS. This study aims to review the application of data mining and machine learning for cyber threat detection, especially in the context of small businesses. A systematic literature review (SLR) with the PRISMA approach was used. Articles were collected from Google Scholar and Semantic Scholar (2018–2026), screened using inclusion and exclusion criteria, and analyzed descriptively. From 19 collected articles, 11 were reviewed: seven on data mining/machine learning for cyber threat detection and four on MSME cybersecurity. The results show that Random Forest, C4.5/J48, SVM/SMO, Naive Bayes, and K-Means are commonly used. Feature selection (Information Gain, PCA) and class balancing (SMOTE) improve accuracy and training efficiency, with reported accuracy generally above 90%. However, most studies use public datasets such as KDD Cup’99, AWID, CICIDS2017, and CIC-MalMem-2022, not data from MSME environments. Key challenges include class imbalance, false positives, limited resources, data quality, scalability, and low digital literacy. Non-technical factors—management commitment, governance, training, and cost—are also critical. Data mining has potential for MSME threat detection, but implementation requires lightweight, context-specific models and organizational readiness.

Abstract

Sharing personal data for research and analysis creates a risk of identifying individuals, because removing direct identifiers alone is not enough. This study implements k-anonymity on 16,007 records of the UCI Adult dataset using five quasi-identifiers (age, sex, race, marital status, native country), with income as the sensitive attribute. The method is full-domain generalization with record suppression (5% limit), evaluating all 180 combinations of generalization levels for k = 2, 3, 5, and 10 in Python. The results show that unique records fell from 1,352 (8.45%) to zero for all values of k, maximum re-identification risk fell to 1/k, and average risk fell from 0.1442 to 0.0341 (k = 2) and down to 0.0045 (k = 10). This protection came with a rise in total information loss from 0.0922 to 0.2471, with 4.2% to 4.7% of records suppressed and age fully hidden at k = 10. In this configuration, k = 5 was a balanced choice between privacy and utility. However, 1.51% to 12.65% of records still sit in classes that are homogeneous in income, leaving them vulnerable to homogeneity attacks, so k-anonymity should be complemented with l-diversity or t-closeness.

Abstract

Phishing URLs can imitate legitimate services and expose users to credential theft. This study compared lexical and structural characteristics of phishing and legitimate URLs using the public PhiUSIIL dataset, which documents 100,945 phishing and 134,850 legitimate URLs. URL strings were parsed offline without visiting their destinations. Eight features were examined: URL length, hostname length, digit proportion, hyphen count, hostname dot count, IP-based hosts, HTTPS scheme, and query presence. After removing 425 duplicate records, 235,370 URLs were analyzed using medians, interquartile ranges, proportions, Mann–Whitney tests, rank-biserial effect sizes, and Holm correction. Phishing URLs showed larger digit proportion (r = 0.45), URL length (r = 0.44), hyphen count (r = 0.30), and host length (r = 0.25), whereas hostname dot count differed negligibly (r = −0.03). HTTPS appeared in 48.6% of phishing URLs versus 100% of legitimate URLs; IP-based hosts and query strings occurred only among phishing URLs. Because all legitimate URLs were HTTPS homepage addresses without paths or queries, these contrasts partly reflect how the classes were built. The features are candidate warning indicators, not deterministic rules.

Abstract

This study examines the effects of competence and work discipline on employee performance and tests work motivation as a mediating mechanism at the Garden Unit of PT Perkebunan Nusantara IV Regional VI Cot Girek, North Aceh. A quantitative cross-sectional survey was conducted with 200 employees selected from a population of 539 using purposive sampling. Data were collected through a five-point Likert questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) in SmartPLS 4. The measurement model satisfied convergent validity, discriminant validity, and internal consistency requirements. Competence had positive effects on work motivation (β = 0.467, p < 0.001) and employee performance (β = 0.286, p < 0.001). Work discipline also positively affected work motivation (β = 0.223, p = 0.001) and performance (β = 0.220, p < 0.001). Work motivation was the strongest direct predictor of performance (β = 0.480, p < 0.001). Indirect effects through work motivation were significant for competence (β = 0.224) and work discipline (β = 0.107), indicating partial mediation. The findings show that employee performance in plantation operations improves when ability and disciplined work practices are supported by stronger work motivation.
