Abstract

Resonant field phenomenon in optical ring resonator has been a major theme for various studies and can be used for various sensor applications. The spectral response shape changes are subjects to be discussed and analyzed for detection in optical sensor system. The spectral response changes are caused by various factors ranging from refractive index of the surrounding medium, medium loss due to absorption and scattering, and coupling variation between waveguides. These optical phenomena are mostly used for bio-sensor applications, since it is free from electromagnetic interference (EMI) and non-physically destructive. In this paper, we discuss our current research in developing optical bio-sensor in the form of a fiber optic ring resonator with monochromatic laser source based on spectral integration detection method, which is sufficiently sensitive and accurate.

Abstract

This study aims to determine the significance of variables and the success of the Pegadaian Digital Services (PDS) application utilizing the DeLone & McLean Information System (D&M IS) Success Model in the Jabodetabek area. This research method uses a quantitative approach, collecting data through questionnaires to active users of the PDS application in Jabodetabek. The collected data was processed using the SEM-PLS model with the SMARTPLS3 tool. The findings indicate that user satisfaction is significantly impacted by system quality, information quality, as well as service quality. However, net benefits are not strongly influenced by user satisfaction. Nevertheless, net gain is not much impacted by user satisfaction. Furthermore, both system quality and information quality also have a significant and positive effect on net benefit. The overall success rate of the PDS application is 84% which means that the PDS application is very successful, which is analyzed from the user’s perspective and the D&M IS Success Model is effective in measuring application success. This finding is expected to be an evaluation material in improving the quality of PDS applications and for further research can expand the coverage area, explore additional factors, and conduct research with direct interviews with users.
