    Digital technology has rapidly developed in recent years, affecting the culture and patterns of transactions. One of the innovations in digital payments is the emergence of the Quick Response Indonesian Standard (QRIS). However, massive QRIS education at all levels of society is not in line with the community's response, which still maintains traditional payment patterns, especially in the Soloraya area. This study aimed to analyze the factors influencing the adoption of QRIS (technology use). This approach was carried out using technology acceptance model modification theory. A sample of 100 people was obtained using a simple random sampling method in communities located in the former Surakarta (Soloraya) residency, namely Sragen, Sukoharjo, Karanganyar, Wonogiri, Klaten, Boyolali and Surakarta City Regencies. Data analysis techniques with partial least squares structural equation Modelling (PLS-SEM). The results show that all variables in the TAM modification construct consisting of perceived usefulness, perceived ease of use, perceived risk and perceived security influence the decision to use QRIS with intention as a mediating variable

    The objective of this study is to determine the influence of pressure (financial targets, financial stability, and external pressure), opportunities (industry characteristics and ineffective monitoring), opportunities (auditor turnover and rationalization), and capabilities on Fraudulent Financial Reporting in Manufacturing Companies listed on the Indonesia Stock Exchange from 2017 to 2021. The research approach employed a quantitative method, namely utilizing panel data regression analysis, with the assistance of Eviews 9.0 software. Financial objectives have a positive and significant influence on misleading financial reporting. Financial stability, rationalization, and poor monitoring have a significant negative impact on inaccurate financial reporting, while external pressure, industry type, auditor turnover, and capability do not have a significant influence on inaccurate financial reporting. In subsequent research, it is expected to include a greater number of independent variables and a larger sample size in order to yield more robust research findings

    The purpose of this research is to examines how is the competition and pricing for audit services in the audit service market in Indonesia from the perspective of the auditors. This study uses a questionnaire with auditor respondents at manager level to audit partners. The data analysis technique used in this research is descriptive statistical analysis. By using a total of 414 respondents from audit firms Big 4 and non-Big 4, this research found that most of the respondents considered the audit service market competition in Indonesia to be high and agree that competition for audit services creates pressure that creates relatively low audit fee in Indonesia. The results of this study confirm and strengthen previous studies which using secondary data that the level of concentration of the audit services market is related to the level of competition for audit services and create pressure to reduce audit fee.  The implication of this research is that further research needs to be carried out using more objective secondary data to examine the impact of the level of competition of audit services on audit fees and audit quality as well as evaluating whether regulations are needed to determine minimum audit fees

    The Characterization of Mechanical and Chemical Properties of Recycled Styrofoam Waste Employing Extrusion Process

    Get PDF
    Styrofoam waste is a polystyrene plastic-based waste in the form of foam with low density. Scavengers or recyclers are not interested in receiving styrofoam waste because of its light density which makes it ineffective in transportation and storage. Styrofoam waste can actually be converted into solid polystyrene products through a thermal-extrusion process but data regarding the optimum operating temperature and the characteristics of the resulting solid polystyrene products are not yet available. The purpose of this study was to investigate the properties of solid polystyrene products resulting from recycled styrofoam waste and determine the optimum temperature of the thermal-extrusion treatment process to be compared with the characteristics of the original polystyrene based on the results of tensile and impact tests. In this study, the processing was carried out using the thermal-extrusion method; Styrofoam is melted and extruded into a mold to produce polystyrene solids. The research was carried out with variations in extrusion temperature at 180°C, 200°C, and 220°C. The polystyrene solids are then molded into tensile and impact test specimens by injection molding. The results showed that the optimal extrusion temperature was 200°C with tensile and impact strength values of 27.55 MPa and 1,069 j/m2, respectively. Compared to the original polystyrene, the tensile strength value is 25.3% lower and the impact strength value is 29.5% lower. The decrease in the tensile and impact strength values is due to the shortening of the molecular bonds in the recycled polystyrene during the thermal-extrusion treatment process. Even though the tensile strength and impact are still lower, the use of styrofoam waste using the thermal-extrusion method has the potential to be developed at the production and commercialization stage because the resulting product has good economic value and can also reduce the use of original polystyrene and at the same time can solve the problem of styrofoam waste
