Abstract

Cellulase enzyme activity can be increased by concentrating the enzyme using saturated ammonium sulfate ((NH4) 2SO4) 80%. Precipitated enzyme was redissolved by the addition of acetate buffer solution pH 5.5 to 1/70 times its original volume. Cellulase enzyme activity was determined using substrates CMC and avicel. The test results showed that the activity of concentrated CMCase increased 75 times and avicelase enzyme activity increased 9 times. Activity and specific activity concentrated CMCasewas 0,4060±0,0845 U/ml and 0,7306±0,1526 U/mg respectively, while activity and specific activity of concentrated avicelase were 0,0129±0,0182 U/ml and 0,0232±0,0328 U/mg respectively.

Abstract

This study aims to analyze the influence of Tax Knowledge and Tax Morale on Tax Compliance Intention among Generation Z in South Tangerang. A quantitative approach was employed using multiple linear regression analysis with the assistance of IBM SPSS Statistics version 27. The sample consisted of 100 Generation Z respondents selected through purposive sampling. Data were collected using a Likert-scale questionnaire and analyzed through validity and reliability testing, classical assumption testing, t-tests, and the coefficient of determination. The results indicate that Tax Knowledge has no significant effect on Tax Compliance Intention, while Tax Morale has a positive and significant effect on Tax Compliance Intention. These findings highlight that moral and ethical considerations play a more dominant role than technical tax knowledge in shaping the tax compliance intention of Generation Z.
