The implementation of Environmental, Social, and Governance (ESG) regulations in Indonesia is still in its developmental stage and faces several challenges in enforcement and compliance. Compared to developed countries, Indonesia's ESG framework lacks strong incentives and adequate regulatory oversight, leading to inconsistencies in corporate adherence. This study aims to analyze the effectiveness of ESG regulations in Indonesia from a legal perspective and evaluate their impact on corporate compliance. A normative juridical approach was used, supplemented by case studies of companies that have implemented ESG principles. Data were collected through document analysis of regulatory frameworks, sustainability reports, and interviews with key stakeholders. The findings indicate that while the number of companies adopting ESG practices has increased significantly from 45 in 2018 to 675 in 2023, only 38% fully comply with ESG standards. Moreover, statistical analysis reveals a strong correlation (r = 0.78, p < 0.05) between regulatory strictness and corporate adherence. Weak enforcement mechanisms and the voluntary nature of ESG reporting remain major obstacles to effective implementation. The study also highlights that firms integrating ESG principles tend to attract more investment and demonstrate better financial stability. The findings contribute to the ongoing discourse on ESG regulation by emphasizing the need for policy reforms, including stricter enforcement, standardized reporting mechanisms, and economic incentives to enhance compliance. This research provides a foundation for future comparative studies on ESG regulation and suggests integrating technology-based monitoring tools such as blockchain and artificial intelligence to improve corporate accountability and sustainability practices.

The results show that this relationship harms public interests and hinders governance quality. The study offers recommendations to address these issues to enhance transparency and accountability.

An agreement is when a person commits to another person to do something or when both parties commit to carry out something. However, in practice, there are often cases of default, where there are parties who do not fulfill their obligations in accordance with the contents of the agreement, as happened in the case of a kiosk sale and purchase agreement in Kupang District Court Decision Number 132.18/PDT.G/2016/PN.KPG. This article aims to analyze the occurrence of default in the kiosk sale and purchase agreement and analyze the judge's decision in resolving the default with the principles of justice. This article adopts a qualitative approach by using the normative juridical method and conducting a literature study. The results of this research analysis explain that the judge's decision in this case has fulfilled the necessary conditions. The Defendant has been found in default by the Panel of Judges and is entitled to pay the remaining money according to the agreement letter. The principles of legal certainty and justice have also been applied properly by considering all evidence and witness testimony before making a decision.

All companies hope for an effective and efficient production system, but an imperfect production system means that PT XYZ must improve its production activities. The company strives to produce good products followed by a high level of productivity. In this research, we investigate a case at PT XYZ which produces hot stamping foil in the rewind section. This research found that there was waste that occurred in set-up replacement activities in production. Because it requires a long processing time, we perfected the system by implementing the Single Minute Exchange of Dies (SMED) method, then the process optimized internal activities in the set-up process. The application of the SMED concept is carried out by changing internal activities into external activities with the addition of helpers. This research aims to provide a more effective and efficient set-up replacement process so that machine downtime can be reduced. The results of this research show a 52% reduction in set-up time obtained by adding a helper with a time before implementation of 58 minutes to 30 minutes. This research concludes that SMED is effective in reducing machine set-up time and increasing the efficiency of the production process with benefits after implementing the SMED method by adding a helper of Rp. 10,649,336. In this way, implementing the SMED method helps companies increase production set-up replacement times in the rewind section.
 

The predictive role of oxidative stress in the pathophysiology of human pregnancy is of particular interest, as oxidative stress is increased in normotensive pregnant women through systemic inflammatory response, reactive oxygen species (ROS), and reactive nitrogen species (RNS). This study involved 40 consenting pregnant women recruited from St. Philomina Catholic Hospital, Edo State, Nigeria. Data obtained were analyzed using GraphPad Prism 9. Results were expressed as mean ± SEM, with a P-value of ? 0.05 considered statistically significant. Malondialdehyde (MDA) increased from 3.75 ± 0.42 U/L in normotensive women to 4.53 ± 0.59 U/L in preeclamptic women. However, this increase was not statistically significant (p<0.05; 0.2903). Catalase activity decreased from 114 ± 8.07 U/L in normotensive women to 84.02 ± 21.58 U/L in preeclamptic women, but this decrease was also not statistically significant (p<0.05; 0.1909). Superoxide dismutase (SOD) increased from 40.82 ± 1.23 U/L in normotensive women to 71.90 ± 5.61 U/L in preeclamptic women. This increase was statistically significant (p<0.05; <0.0001). Glutathione peroxidase (GSH) decreased from 66.74 ± 10.35 U/L in normotensive women to 50.63 ± 8.96 U/L in preeclamptic women, but this decrease was not statistically significant (p<0.05; 0.2466). These findings suggest the potential predictive roles of these biomarkers in identifying and monitoring preeclampsia.
