Abstract

Dataset curah hujan (CH) dengan resolusi spasial dan temporal yang baik diperlukan oleh berbagai sector seperti sektor manajemen sumber daya air dan bencana hidrologi. Namun, pengamatan CH secara langsung di permukaan seringkali tidak lengkap dan tidak merata. Sumber alternatif data CH lainnya dapat diperoleh dari estimasi CH oleh satelit (penginderaan jauh). Namun, estimasi satelit memiliki kesalahan dan ketidakpastian yang berpotensi mempengaruhi aplikasi selanjutnya yang menggunakan data hujan. Oleh karena itu, penting untuk mengukurketidakpastian estimasi CH satelit untuk memberikan informasi tambahan bagi pengguna mengenai keandalan data. Pada penelitian ini telah dilakukan simulasi Monte Carlo untuk menghasilkan ensemble Dataset CH yang mampu mengkuantifikasi ketidakpastian produk estimasi CH TRMM (Tropical Rainfall Measuring Mission) 3B43v7. Dataset CH ensemble ini dapat digunakan untuk memberikan informasi tentang distribusi error dan estimasi peluang CH dari estimasi satelit TRMM. Dalam kajian ini juga ditunjukkan pemanfaatan dataset CH ensemble dalam mengkuantifikasi ketidakpastian dalam analisis CH ekstrim menggunakan pendekatan periode ulang dan Probable Maximum Precipitation (PMP). Kata kunci: estimasi satelit, TRMM, ketidakpastian, Monte Carlo, ensemble

Abstract

The purpose of this study is to look at where IDX-80 issuers gain financial attention by analyzing the influence of investment, shareholder management, and debt packages. This research focuses on all listed firms in Indonesia for the fiscal year 2021-2023. A random selection approach was utilized to choose 34 organizations as a sample, yielding 102 respondents for this study. The researchers employed a variety of methodologies to investigate the association between factors. Secondary data were acquired from yearly reports, and the data was analyzed using through analysis and SPSS25 with multiple regression. The study found that investment growth has a beneficial impact on investment policies and debt packages. Accounting conservatism is positively impacted, at least in part, by the investment opportunity set, managerial ownership, and debt covenant. Accounting conservatism is correlated with a company's debt ratio. This occurs because firms with a large amount of debt are compelled to obey the terms of the agreements that their creditors have signed with them. As a result, businesses generally use more stringent accounting procedures to ensure they are in compliance with the agreement and avoid any infractions.
