A combination of the partial least square method in its first variable (PLS-1) with micellar-enhanced photochemically- induced fluorescence (MEPIF) was developed for the simultaneous determination of synthetic binary mixtures of four sulfonylurea herbicides in aqueous micellar solutions, and applied to tap water analysis. Because of their similar features, the MEPIF emission spectra of these herbicides were found to severely overlap in the whole wavelength region. After optimization of the calibration matrix, the PLS-1-MEPIF method was applied to the resolution of chlorsulfuron/metsulfuron methyl and sulfometuron methyl/3-rimsulfuron binary mixtures. The analytical results obtained by the PLS-1-MEPIF method were presented and compared to those of the first-derivative PIF one. An application of the PLS-1-MEPIF method to the quantitative analysis of Paris tap water samples spiked with the herbicide binary mixtures led to recovery values ranging between 63 and 118 %, depending on the mixture.

Three drugs such as atropine sulfate ,vitamin C, aminophylline were simultaneously determined by a spectrophotometric method comined with the aid ofchemometrics .The result revealed that the principle component regression and the partial least square method overcome the overlapping of their absorption curves in the UV spectral region.It was shown that the predictive errors obtained by the PCR method was 1.59%. Recovery of the method by standard addition method was respectively valued 100.31% (for atropine sulfate) and 99.42% (for vitamin C) and 97.11% (for aminophylline),.

AbstractThis research aims to analyze the effect of e-filling application and tax volunteer’s role to individual taxpayer’s compliance. In addition, this research also analyzes the effect of tax volunteer’s role as moderating variable on e-filling application to individual taxpayer’s compliance. This research analyzes primary data from distributed questionnaires to 100 individual taxpayers’ in assistance locations of Tax Volunteer from Politeknik Negeri Bali Tax Center. Sample selection in this research using purposive sampling technique. The testing of research variables was conducted using the Partial Least Square method with SmartPLS 3.0 application. The results showed that e-filling application and tax volunteers role had a positive and significant effect on individual taxpayer’s compliance. While there is no significant effect from the moderation of tax volunteer’s role in e-filling application to individual taxpayer’s compliance. This research has a novelty the role of tax volunteers in improving taxpayer compliance. Furthermore, this research has a practical contribution to the tax authority to increase the role of tax volunteers and to taxpayers on the participation of utilizing tax volunteers to improve compliance.Keywords: E-filling; Individual taxpayer; Tax compliance; Tax volunteerAbstrak Penelitian ini bertujuan untuk menguji efek dari penerapan e-filling dan peran relawan pajak terhadap kepatuhan wajib pajak orang pribadi. Di samping itu, dilakukan pula pengujian moderasi relawan pajak atas pengaruh penerapan e-filling terhadap kepatuhan wajib pajak orang pribadi. Penelitian ini menganalisis data primer dari kuesioner yang disebarkan kepada 100 wajib pajak orang pribadi di lokasi asistensi Relawan Pajak Tax Center Politeknik Negeri Bali. Pemilihan sample pada penelitian ini menggunakan teknik purposive sampling. Pengujian variabel penelitian dilakukan menggunakan metode Partial Least Square dengan aplikasi SmartPLS 3.0. Hasil penelitian menunjukkan bahwa penerapan e-filling dan peran relawan pajak berpengaruh positif dan signifikan terhadap kepatuhan wajib pajak orang pribadi. Sedangkan terdapat pengaruh yang tidak signifikan pada moderasi peran relawan pajak atas penerapan e-filling terhadap kepatuhan wajib pajak orang pribadi. Penelitian ini memiliki keterbaruan peran relawan pajak dalam meningkatkan kepatuhan wajib pajak. Penelitian ini memiliki kontribusi praktis pada otoritas pajak untuk meningkatkan peran relawan pajak dan terhadap wajib pajak pada partisipasi memanfaatkan relawan pajak untuk meningkatkan kepatuhan.Kata Kunci: E-filling; Kepatuhan pajak; Relawan pajak; Wajib pajak orang pribadi

This study aims to investigate the effect of the employee stock ownership program (ESOP) on profitability and firm value. In addition, this study also aims to see the mediating effect of profitability on the effect of ESOP on firm value. This research was conducted on manufactures listed on the Indonesia Stock Exchange (BEI) during 2015-2019. The data analysis technique in this study used the PLS (Partial Least Square) method. The results of this study indicate that the results of this study indicate that profitability partially mediates the effect of ESOP on firm value. This study also found that ESOP has a positive effect on profitability and firm value. This study also found the same thing for the effect of profitability on firm value.
