This research investigates the use of photosynthetic bacteria (PSB) and Jakaba liquid organic fertilizer (POC) as sustainable alternatives to chemical fertilizers for post-acclimatization Kepok Bung banana plants. Using a field experiment with a split-plot design, we tested three concentrations of PSB (10 ml/L, 15 ml/L, and 20 ml/L) and three concentrations of Jakaba POC (10 ml/L, 20 ml/L, and 30 ml/L) to determine their effects on plant growth parameters. Results demonstrated a significant interaction between PSB and Jakaba concentrations, with the combination of PSB at 10 ml/L and Jakaba POC at 10 ml/L yielding optimal results. This treatment produced a 37% increase in root number, 42% improvement in plant fresh weight, and 45% increase in dry weight compared to less effective treatment combinations. The enhanced growth can be attributed to improved photosynthetic efficiency, better nutrient absorption, and stimulated root development. These findings provide banana farmers with a practical, environmentally sustainable alternative to chemical fertilizers that effectively supports plant growth during the critical post-acclimatization phase while reducing environmental degradation associated with conventional fertilization methods.

The rise of sustainable finance is in accordance with the increasing emphasis on the need to implement sustainable development globally. However, inadequate research has been done on how sustainability finance practices impacts a company's financial performance. Through sustainability reports and the issuance of green bonds, this research aims to comprehend how sustainable finance practices affect financial performance. Return on Equity (ROE) serves as an indicator for financial performance in this research. The 19 financial services companies listed on the Indonesia Stock Exchange comprised the research's population. Path analysis was used to perform the analysis. The findings show that the issuance of green bonds is positively and significantly impacted by the caliber of sustainability reports. However, the financial performance of Indonesian financial service companies is not significantly impacted by the quality of sustainability reports or the issuance of green bonds. The impact of sustainability report quality on the financial performance of Indonesian financial service companies is positively mediated by the issuance of green bonds. The importance of utilizing green bond issuance as a strategic tool to improve the financial results linked to sustainable reporting practices is highlighted by this finding, which offers useful insights for Indonesian financial service institutions.

Tax compliance of MSMEs plays an important role in increasing state revenues, but still faces obstacles such as limited understanding and ever-changing policies. Tax socialization, reduction in Income Tax (PPh) rates for MSMEs, and tax awareness related to MSME compliance with tax regulations are the focus of this study. A total of one hundred and thirty Ayam Gepuk Pak Gembus franchisees in Jabodetabek were the subjects of the study. The calculation used the Slovin formula with a margin of error of 5% to select a sample of 171 partners using a basic random sampling approach. Data analysis used SmartPLS software and Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results of the study showed that tax awareness did not have a significant effect on compliance, but tax socialization and rate reductions had a significant effect. This indicates that simpler policies and effective socialization have a greater influence on compliance than the level of taxpayer knowledge. Implications for the government in designing strategies to improve MSME tax compliance through intensive socialization and more accessible tax policies. This suggests that simplifying tax policies and improving socialization efforts are more effective than merely increasing taxpayer knowledge. The results offer insights for policymakers to refine strategies that encourage MSME tax compliance through accessible regulations and targeted outreach.

The construction of warehousing and supporting facilities at Juwata Airport has several obstacles that cause delays in the implementation of the work, so a work control method is needed, namely the earned value method by assessing the cost and time performance of project implementation such as Cost Variance (CV), Schedule Variance (SV), Schedule Performance Index (SPI), and Cost Performance Index (CPI) as well as the estimated cost and time of project completion. The purpose of this research is to calculate the amount of cost needed to complete the project of Warehousing Development Package and Supporting Facilities of Juwata Airport on time according to the plan schedule. The method used is the Earned Value Method in evaluating cost performance and time performance. The analysis carried out uses 3 (three) indicators, namely ACWP (Actual Cost of Work Performance), BCWP (Budgeted Cost of Work Performance) and BCWS (Budgeted Cost of Work Scheduled). By using the earned value method, the final project cost estimate obtained from the EAC is Rp. 15,019,062,678.43 and the estimated time / Time Estimate (TE) at week 26 shows 239 calendar days so that the completion time is 28 days late from the contract schedule. And the solution to the delay is to accelerate the work with an additional cost of Rp. 68,970,000. Future research should explore optimization strategies to enhance efficiency in cost estimation and project scheduling.
