Therefore, auditors must always maintain their competence through continuous professional development. This study describes the competency development program focusing on formal degree education and professional certification for BPK employees. Furthermore, this study measures the adequateness of such a program compared to the allocation in competency development planning, as well as advantages and challenges according to employee perceptions. This study uses secondary data from the 2016-2020 Competency Development Activity Report, the 2019 BPK Peer Review Report, and a questionnaire study. The result shows that BPK has actualized competency development through formal degree education and professional certification program. However, the actualization of competency development with professional certification in 2016-2020 has not yet fully met the allocation stipulated in BPK's Human Capital Development Plan. Employees' perception shows high interest in competency development through formal degree education programs and professional certifications. However, these interests are met with several challenges. One of the challenges that arise involves career advancement and inclusiveness of competency development for all employees, including non-auditor and non-accounting employees. This study suggested further research on conducting a more comprehensive evaluation to ensure that implementing competency development contributes to BPK's capacity.","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48701561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to examine differences in regional financial performance before the pandemic (2019) and during the pandemic (2020) and to examine the effect of the ranking and status of local government administration published by the Ministry of Home Affairs on regional financial performance in the period before the pandemic (2019) and during the pandemic (2020). Paired sample t-test and regression analysis were used to test the hypotheses on the financial performance of 118 local governments consisting of 16 provincial governments, 48 ​​district governments, and 54 city governments. The regional financial independence ratio (RKKD), the effectiveness and efficiency ratio of PAD, the activity ratio, and the growth ratio are financial performance indicators tested in this research. The research's results show the differences between before and during the COVID-19 pandemic in regional financial performance in the PAD effectiveness ratio, capital expenditure activity ratio, and growth ratio. However, there is no difference in regional financial performance before and during the COVID-19 pandemic as measured by the regional financial independence ratio, efficiency ratio, and operating expenditure activity ratio. The results also show that the ranking and status of local government administration have no effect on regional financial performance before and during the COVID-19 pandemic.","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48525840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses panel data analysis with 228 districts/city government entities from 2014 to 2018. The analysis is conducted in two stages; the first stage measures the efficiency of every local government by using Data Envelopment Analysis (DEA) method. The second stage estimates the effect of accountability and other control variables on local government expenditure efficiency by regression using the Tobit method. The result shows a non-linear relation between accountability, which is proxied using the Indonesia Audit Board Opinion Index, and the efficiency of local government expenditure. Initially, accountability will proceed hand in hand with increasing efficiency; however, at a certain point, an increase in accountability will no longer increase the efficiency level of local government expenditure. Another control variable that positively relates to efficiency is population expenditure per capita. Meanwhile, the ethnic fractionalization index (EFI) and distance negatively affect efficiency. The results of this study have not been able to show a relation between political competition and the gender of regional heads with efficiency.","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42225355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, intergovernmental transfers could also reduce the urgency of local governments to increase their financial independence. This study is designed to prove whether intergovernmental transfers can improve regional financial independence and social welfare. Based on a statistical test of 500 districts/cities throughout 2017—2019 using multiple linear regression analysis, more than 90% of districts/cities have yet to achieve independent financial status. In addition, regional welfare in the country is still experiencing inequality. This study's result shows Revenue Sharing Fund (Dana Bagi Hasil, DBH), General Allocation Fund (Dana Alokasi Umum, DAU), and the previous year's Physical and Non-Physical Special Allocation Funds have a significant and positive effect on regional financial independence. However, only General Allocation Funds and Non-Physical Special Allocation Funds significantly and positively affect social welfare. Whereas Revenue Sharing Fund has an insignificant and negative effect, Physical Special Allocation Funds have a significant and negative effect on social welfare.

This study examines the effect of the maturity of the government's internal control system and the capability of the government's internal auditors on the accountability of local government performance, with control variables, namely audit opinion, local own-source revenues, and proliferation status. It aims to fill the gap using the Indonesian case. This study uses secondary data with sample selection using the purposive sampling method. Local governments in Indonesia from 2017 to 2019 are used as samples. The results of this study indicate that the government's internal control system's maturity, internal auditors' capability, and audit opinions positively affect local governments' performance accountability. In contrast, local own-source revenues and proliferation status negatively impact local governments' performance accountability. The implication of this study is to increase the accountability of local government's performance and continue to improve the maturity of the government's internal control system to achieve at least level 3 (Integrated). The capability of internal government auditors needs to achieve at least level 3 (Defined); thereby, the internal control function of local governments can be optimal.\u0000 \u0000 \u0000 \u0000 ","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46591804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used the data of the 2015-2019 Statement of Budget Realization of Tulang Bawang Barat Regency and primary data from interviews. The research method applies a qualitative approach with an inductive methodology using several financial ratios such as the effectiveness of Local Own-source Revenue management, the ratio of the degree of decentralization, the ratio of regional financial dependence, and the ratio of regional financial independence. Based on the results, the ratio of regional financial independence shows an average of 1.54%, within the 0-25% interval, and classified under the shallow criteria. It may be inferred that regional financial independence in meeting its funding needs for the administration of government affairs is still very low. The regional financial dependence ratio shows an average of 85.99%, categorized as a very high dependency. The calculation of the ratio results proves that the local own-source revenue of Tulang Bawang Barat Regency is still low. Furthermore, a large number of mandatory spending from the central government and national budgeting politics causes the regional financial independence of Tulang Bawang Barat Regency to become low.","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49428077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such a gap persists both in the private and public sectors. Meanwhile, there are only a few studies related to this topic in the public sector, so the need to undertake more research in this area is encouraged. This study investigates to what extent the audit expectation gap occurs in Indonesia’s public sector. It also examines the effectiveness of the additional information in the audit report as mandated by the state financial auditing standards (SPKN, 2017) in closing the gap. A questionnaire was developed and administered to auditors, government officers, and students to capture their views. ANCOVA and Kruskal-Wallis were used to analyze the data collected from the questionnaires. The study discovered that the audit expectation gap in Indonesia’s public sector is related to the auditor’s responsibility. Such a gap is also found in frauds and errors in unqualified financial statements.","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46999897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the preceding, current practice in auditing shows that many auditors use Risk-Based Audit (RBA) to determine an appropriate audit scope. RBA could effectively guide auditors to define audit scope based on the assessed risk. However, RBA does not consider human factors in performing audits. Consequently, most auditors encounter time budget pressure in meeting tight audit deadlines. Such an issue could adversely affect auditors' productivity and health. On the other hand, ergonomics is a discipline that focuses on human capabilities in completing tasks. The study also guides employees to adapt to the job while improving their well-being and increasing the quality of work results. Therefore, this study aims to intervene the principles of RBA with ergonomics. RBA consists of three stages: risk assessment, response, and reporting. The authors have concluded that ergonomics could intervene in RBA in the risk response step once the risk level is determined in the risk assessment phase by conducting a literature review study. Therefore, the auditors should balance the time budget allocation based on the assessed audit risk (low, moderate, or high). As the entity's risk is high, the audit team should be given an extended time allocation and vice versa. The findings suggest that auditors should develop an appropriate time budget scheme for specific audit procedures based on the assessed risks resulting from RBA implementation.\u0000 ","PeriodicalId":31962,"journal":{"name":"Jurnal Tata Kelola dan Akuntabilitas Keuangan Negara","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42898594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
