In this study, synthesized N'-(2-methoxybenzylidene)-4-hydroxybenzohydrazide and N'-(4-nitrobenzylidene)-4- hydroxybenzohydrazide in two step reaction by using methylparaben as starting material has been performed. Methylparaben was treated with hydrazine hydrate to obtain 4-hydroxybenzohydrazide. The reaction was carried out by microwave irradiation resulting 91 % yield. The obtained compound was then reacted with 2-methoxbenzaldehyde or 4- nitrobenzaldehyde to accomplish the target molecule, N'-(2-methoxybenzylidene)-4-hydroxybenzohydrazide and N'-(4- nitrobenzylidene)-4-hydroxybenzohydrazide in 55% and 72% yield respectively. Identification of N'-(2- methoxybenzylidene)-4-hydroxy benzo hydrazide and N'-(4-nitrobenzylidene)-4-hydroxybenzohidroksida was performed by FT-IR, MS, 1H-NMR, and 13C-NMR spectroscopy. In silico study was done with receptor pdb 1C14. The N'-(4- nitrobenzylidene)-4-hydroxybenzohydrazide exhibited antimicrobial activity against Escherichia coli (MIC=31.3 ppm), Bacillus subtilis (MIC=500 ppm). Antimicrobial activity of N'-(2-methoxybenzylidene)-4-hydroxybenzohydrazide against Bacillus subtilis (MIC=31.3 ppm) and MIC= 500 ppm against Escherichia coli.

The study aims to prove and empirically test the effect of good corporate governance (GCG) and environmental performance on carbon emission disclosure. Good corporate governance variables include independent board of commissioners, board of directors, audit committee, institutional ownership, and managerial ownership. The object of this research is mining companies and property companies listed on the Indonesia Stock Exchange (IDX) fot the 2021 period. The sample of this research was obtained using purposive sampling method which was taken from 100 companies that met the criteria from a total of 146 mining companies and property companies in the 2021 period. The analysis model used in this research is a multiple linear regression model. The result showed that the board of directors, audit committee, and environmental performance have a positive and significant effect on carbon emission disclosure. While the independent board of commissioners, institutional ownership, and managerial ownership have no influence on carbon emission disclosure.
