Abstract

Garbage accumulation in Pangkalpinang City continues to increase every year. This research analyzes the influence of input factors on output and analyzes the efficiency of waste processing in sub-districts in Pangkalpinang City. Then this research will also develop strategies that can be implemented to increase the efficiency of waste processing in sub-districts in Pangkalpinang City. The analysis technique used in this research uses quantitative analysis and qualitative analysis. Quantitative analysis uses stochastic frontier analysis (SFA), while qualitative analysis uses Triple Helix Analysis. The data used is monthly data from 2020 to 2022. This research found that the input factors that influence the efficiency value of waste processing in Pangkalpinang City are not yet appropriate. Then this research also shows that waste processing in Pangkalpinang City is technically efficient. However, there were findings of inefficiency in the model which had an effect of 906555.04 percent. This indicates that there are the most important input factors that should be in the model. Increasing waste processing in Pangkalpinang City is prioritized in the recycling program. The Triple Helix aspect needs to be considered as a priority because it has an impact on the sustainability of increasing waste processing in Pangkalpinang City, so it is necessary to develop a Triple Helix strategy. There are six programs that need to be promoted to stakeholders, namely: guidance, mentoring, guidance/training, funding, technology and information.

Abstract

This study aims to analyze the effect of compliance with the Indonesian Appraisers’ Code of Ethics (KEPI) and the implementation of Indonesian Valuation Standards (SPI) on valuation quality, with appraisers’ educational intensity serving as a mediating variable among public appraisers in Indonesia. The study employed a quantitative approach using explanatory research. The research population consisted of 845 public appraisers registered with the Center for Financial Profession Development (PPPK). The sampling technique used proportional random sampling, resulting in 100 respondents. Data were collected through online questionnaires using a Likert scale and analyzed using path analysis and the Sobel test. The results indicate that compliance with the Indonesian Appraisers’ Code of Ethics has a positive and significant effect on appraisers’ educational intensity and valuation quality. The implementation of Indonesian Valuation Standards also has a positive and significant effect on appraisers’ educational intensity and valuation quality. In addition, appraisers’ educational intensity has a positive and significant effect on valuation quality. The mediation test results reveal that appraisers’ educational intensity significantly mediates the relationship between compliance with the Indonesian Appraisers’ Code of Ethics and valuation quality, as well as the relationship between the implementation of Indonesian Valuation Standards and valuation quality. This study demonstrates that improving valuation quality is influenced not only by ethical compliance and the implementation of valuation standards directly, but also through strengthening professional competence via continuing professional education. Therefore, professional organizations and related institutions should strengthen ethical enforcement, implementation of valuation standards, and participation in continuing professional education programs to improve valuation quality in Indonesia.
