Despite this, numerous parties continue to support the execution of Qanun Jinayah, as they have complied with the exact law recognized by the Indonesian government
Reinforcing Corporate Accountability in Indonesian Environmental Law: A Dialectical Examination of Strict Liability and Criminal Sanctions
Full text linkCorporate accountability in Indonesia's environmental law still faces fundamental challenges, especially in the aspect of applying criminal sanctions against legal entities that commit environmental pollution or destruction. In practice, law enforcement relies more on administrative approaches or civil lawsuits, which often do not provide a deterrent effect and tend to be inadequate in responding to the complexity of environmental damage caused by corporations. This research aims to fill this gap by critically examining how the principle of strict liability can be integrated with the criminal sanction mechanism in national environmental law. With a normative juridical approach and supported by relevant case studies, this study shows that the synergy between the two approaches is able to form a more accountable, effective, and responsive accountability framework to the principles of sustainable development. The results of the analysis recommend the need for a holistic environmental law enforcement model, which not only emphasizes the repressive aspect, but also encourages structural improvements in corporate supervision and active public involvement in overseeing environmental law enforcement in Indonesia

The Effect of Green Accounting and Tax Avoidance on Firm Value Moderated by the Board of Directors in Manufacturing Companies
Full text linkThis study aims to examine the effect of green accounting and tax avoidance on firm value, with the board of directors as a moderating variable. The research uses a quantitative approach with panel data regression analysis based on 86 manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2019 to 2023, totalling 430 firm-year observations. The results show that green accounting has a significant negative effect on firm value, indicating that environmental cost disclosures are not yet perceived positively by the market. Meanwhile, tax avoidance has a significant positive effect, reflecting its perception as an efficiency strategy by investors. Although the board of directors does not directly affect firm value, it significantly moderates the relationships between the independent variables and firm value: weakening the negative impact of green accounting and strengthening the positive impact of tax avoidance. These findings highlight the importance of corporate governance in managing environmental and fiscal strategies to optimize firm value
