Determinants of tax avoidance: evidence from basic materials sector companies listed on the Indonesia Stock Exchange

Maurel Salsabilah — 2026-01-17

This study aims to examine the effect of firm size, profitability, and fixed asset intensity on tax avoidance. The population of this research consists of companies in the basic materials sector listed on the Indonesia Stock Exchange (IDX) during 2022–2024. The sampling technique applied was purposive sampling of 112 companies, from which 13 companies were selected as samples over a three-year research period, resulting in a total of 39 sample data points. Data analysis was conducted using IBM SPSS Statistics 25, which included descriptive statistical analysis, pooling data tests, classical assumption tests, multiple linear regression analysis, and hypothesis testing. The results indicate that firm size has a negative effect on tax avoidance, profitability has a positive effect on tax avoidance, while fixed asset intensity has no effect on tax avoidance.

External factors as mediators of work-life balance for generation Z

Hendratmoko Hendratmoko — 2026-02-10

The contemporary landscape of human resource management has witnessed work-life balance (WLB) emerging as a critical strategic concern, particularly for Generation Z employees entering today's evolving work environment. The progression of digitalization, increasing productivity expectations, and individual aspirations for well-being have intensified the relevance of examining WLB. This study investigates how technological and psychological dimensions influence WLB and explores the mediating function of external factors in that relationship. Employing a quantitative methodology anchored in Structural Equation Modeling with Partial Least Squares (SEM-PLS) analysis, complemented by qualitative insights drawn from Gen Z employees' workplace experiences across various Indonesian firms. The findings reveal that psychological variables exert the strongest impact on WLB, both directly and through external mediating factors. In contrast, technological aspects have a limited direct effect and show insignificant mediation. The novelty of this study lies in conceptualizing external conditions such as social support networks and adaptive organizational culture as intermediaries connecting technological and psychological influences on WLB, a perspective rarely explored among Indonesia's younger workforce. The results highlight the importance of psychosocial-oriented strategies in addressing WLB challenges amid the digital era.

Cash optimization with cash management model approach: The case of PT Pertamina Gas (Pertagas)

William Ben Gunawan — 2026-03-11

This study examines the optimization of corporate cash management at Pertagas amid heightened volatility in the energy sector, fluctuating exchange rates, inflationary pressures, and internal demands for CapEx–OpEx efficiency. Using a quantitative approach, this research evaluates Pertagas’s cash cycle and liquidity profile, and applies five cash management models—Baumol, Beranek, Miller-Orr, Stone, and Orgler—to determine optimal cash balances under varying assumptions of certainty and uncertainty. Results indicate substantial volatility in net cash flows, with a Value at Risk (VaR) of –USD 81.48 million at the 95% confidence level. Model estimations recommend optimal daily cash levels ranging from USD 1.05 million (Baumol) to USD 4.51 million (Miller-Orr), significantly lower than the company’s existing Rp 200 billion (≈ USD 12.5 million) policy threshold, implying notable opportunity costs from holding idle cash. The Orgler model further shows that Pertagas could generate up to USD 10.89 million annually through optimized deployment of surplus liquidity. The study recommends integrating stochastic and forecasting-based models, strengthening cash monitoring systems, and revising minimum cash policies to enhance liquidity, profitability, and financial resilience.
