Background: The global energy transition requires low-carbon solutions that can be integrated into existing thermal systems without drastic infrastructure changes. Hydrogen blending in conventional combustion systems has emerged as a promising pathway to reduce carbon emissions while maintaining operational flexibility. Objective: This study aims to experimentally evaluate the effect of hydrogen blending ratios (0–100% by volume) on thermal efficiency, CO₂ emissions, and NOx emissions, and to determine the optimal blending range based on technical and economic feasibility. Methods: An experimental thermal system prototype was developed and tested under controlled conditions with three repetitions per operating point. Performance parameters included combustion temperature, fuel consumption rate, and thermal efficiency, while emissions of CO₂ and NOx were measured using a calibrated gas analyzer. Data were analyzed using descriptive statistics, one-way ANOVA at a 0.05 significance level, confidence interval estimation, and linear regression to examine the relationship between hydrogen fraction and emission reduction. Results: The findings indicate that increasing hydrogen fraction significantly improves thermal efficiency, reaching 87.5% at 100% hydrogen, while CO₂ emissions decrease linearly to zero. However, NOx emissions increase with higher hydrogen content due to elevated combustion temperatures. Statistical analysis confirms that hydrogen ratio has a significant effect on efficiency and emissions, with a strong linear correlation between hydrogen fraction and CO₂ reduction. A blending range of 40–60% hydrogen provides the most balanced performance in terms of efficiency improvement, emission reduction, and cost feasibility.

This study aims to analyze the impact of acquisitions on the profitability of non-financial companies listed on the Indonesia Stock Exchange (IDX), using Return on Assets (ROA) and Net Profit Margin (NPM) indicators as the main proxies. This study uses a quantitative approach with descriptive analysis methods and paired t-tests on two years before and two years after the acquisition. The results showed that in the ROA indicator, there was no statistically significant difference before and after the acquisition, although there was a descriptive decrease in value. Meanwhile, in the NPM indicator, only one of the four combinations of observation years (T-2 vs T+2) shows a significant difference, and the direction of change shows a drastic decrease until it reaches a negative value. This finding indicates that acquisitions do not necessarily increase company profitability, and even tend to have a negative impact within two years after the acquisition. This may be due to the non-optimization of the post-acquisition integration process. This study emphasizes the importance of careful integration planning and implementation so that the expected synergy benefits from acquisitions can be achieved
