Abstract

Penelitian ini memproduksi karagenan murni dari rumput laut Eucheuma cottonii menggunakan ekstraksi konvensional dengan pelarut KOH serta mengevaluasi pengaruh konsentrasi KOH terhadap kualitas produk. Ekstraksi dilakukan pada suhu 90°C selama 3 jam (pH 9) dengan variasi KOH 0,1 M, 0,5 M, dan 1,5 M. Hasil terbaik diperoleh pada konsentrasi KOH 1,5 M dengan rendemen 50%, kadar air 9,5%, kadar abu 36,98%, kadar abu tak larut asam 6,98%, viskositas 3 cP, dan kekuatan gel 5278,45 g/cm². Karakterisasi FTIR menunjukkan jenis kappa karagenan, ditandai oleh puncak 3,6-anhidrogalaktosa pada 923,93 cm⁻¹ dan galaktosa-4-sulfat pada 835,21 cm⁻¹. Konsentrasi KOH terbukti berpengaruh signifikan terhadap mutu karagenan yang dihasilkan.

Abstract

This study aims to examine the effect of green culture and CSR on financial performance with the application of XBRL as a moderating variable. This research method uses quantitative and secondary data. The sample used in this study is manufacturing companies listed on the IDX in 2020 with the measurement of financial performance variables using the ROA formula, green culture using an index, CSR using an index, and the implementation of XBRL using an index. The stages for the analysis method are descriptive statistics analyzing the mean, minimum, maximum and standard deviation; assumption test: assumption of normality, assumption of absence of multicollinearity symptoms, assumption of autocorrelation, and assumption of heteroscedasticity; the normality test of the data, namely the Kolmogrof-Smirnov statistical test; determinant coefficient (R2); and hypothesis testing. The results show that green culture has a positive effect on financial performance, CSR has a positive effect on financial performance, the application of XBRL strengthens the relationship between green culture and financial performance, the application of XBRL strengthens the relationship between CSR and financial performance.

Abstract

E-government represents a governmental adaptation aimed at enhancing digital public service. The Regional Revenue Management Agency (Bapenda) of Central Java Province has developed an e-government application called New Sakpole, designed to facilitate online motor vehicle tax payments for the public. However, the application has been perceived as presenting challenges, such as difficulties in use and limited utility, leading to dissatisfaction. This study examined the relationship between perceived ease of use and perceived usefulness on user satisfaction with the New Sakpole application for motor vehicle tax payments in Central Java. Employing a quantitative approach, primary data were collected from 100 respondents and analysed using Spearman's rank correlation and multiple regression analysis. The findings indicate a significant positive relationship between perceived ease of use and user satisfaction, with a 59.7% contribution to the model. Perceived usefulness also showed a positive and significant correlation with satisfaction, contributing 41.2%. Simultaneous analysis of the two variables further demonstrated a significant positive relationship of 68.3%. The study concluded that all tested variables exhibited a positive and significant relationship, underscoring the importance of perceived ease of use and usefulness as key indicators for enhancing user satisfaction. The more accessible and beneficial an application is, the higher the level of user satisfaction.
