Abstract

This study aims to evaluate the effectiveness of online training on the recommendation intention of port employees in Indonesia. The research employed a quantitative approach using a survey method. The population consisted of 181 employees who had participated in online training programs, and saturated sampling was applied, involving the entire population as respondents. Data were collected through a Likert-scale questionnaire (1–5) and analyzed using SPSS version 29. The analysis included validity and reliability tests, classical assumption tests, multiple linear regression, t-test, and F-test. The results indicate that perceptions of training components simultaneously have a significant effect on recommendation intention (F-test, p < 0.05). However, the coefficient of determination (R² = 0.131) shows that these variables explain only 13.1% of the variance in recommendation intention. Partially, perceived trainer quality has a significant positive effect, while perceived benefits show a significant negative effect. Perceptions of training materials and facilities do not significantly influence recommendation intention. These findings highlight the crucial role of trainer competence in shaping employees’ willingness to recommend online training programs. The study suggests that training providers should focus on improving trainer quality and managing participants’ expectations regarding training benefits. Future research is recommended to incorporate additional variables such as satisfaction, loyalty, and organizational support to develop a more comprehensive predictive model.

Abstract

Indonesia’s rapid expansion of nickel mining and downstream processing has positioned the country as a key supplier for the global energy transition, yet it has also generated significant environmental externalities. This study examines how nickel industrialization produces cumulative environmental impacts through interconnected transmission pathways and how these impacts affect ecosystems, human health, and biodiversity. Using a qualitative, pathway-based analytical framework, the research synthesizes peer-reviewed literature indexed in Scopus, policy and regulatory documents, environmental reports, and spatial evidence, with a focus on major nickel-producing regions such as Morowali, Halmahera, and Raja Ampat. The findings demonstrate that environmental externalities in the nickel sector are systemic rather than isolated. Air pathways transmit particulate matter and gaseous emissions that degrade terrestrial ecosystems and increase health risks. Water pathways convey heavy metals and sediments into riverine and coastal systems, undermining aquatic ecosystem functions, food security, and public health. Land pathways drive deforestation, soil degradation, and habitat fragmentation, resulting in long-term losses of ecosystem services and biodiversity. These impacts interact across pathways, producing cumulative and spatially dispersed effects that disproportionately burden local communities. By integrating multiple environmental pathways and receptors, this study addresses a critical gap in existing literature that has largely relied on sectoral or single-impact analyses. The results underscore the need for integrated, pathway-aware governance approaches to internalize environmental costs and support sustainable nickel-led development.
