Credit Metrics is a reduced form model to estimate the risk of displacement of ratings. The risk not only occur when corporate rating be default but also if the rating upgrade or downgrade. For the determination of the portfolio valuation can be used Monte Carlo simulation using generate scenarios corporate ratings. Empirical study can be used for three bonds there are Obligasi II Bank Danamon Tahun 2010 Seri B, Obligasi II Telkom Tahun 2010 Seri A, and Obligasi Indofood Sukses Makmur V Tahun 2009.

Abstract

The Bhumi ATR/BPN application was developed as an interactive geospatial information system to support the digital transformation of public services at the Ministry of Agrarian Affairs and Spatial Planning/National Land Agency (ATR/BPN). This study aims to analyze user satisfaction with the Bhumi application using the End-User Computing Satisfaction (EUCS) model, which includes five dimensions: content, accuracy, format, ease of use, and timeliness. A quantitative approach was applied through the distribution of questionnaires to 427 users. Regression analysis revealed that content (β=0.237), accuracy (β=0.181), and ease of use (β=0.292) significantly influenced user satisfaction (p<0.01), while format and timeliness did not show significant effects. Collectively, the five variables explained 46% of the variance in user satisfaction (R²=0.460). The limitation of this study lies in the use of purposive and convenience sampling methods, which tend to represent active users with reliable digital access. The findings provide important recommendations for the development of public sector information systems, particularly in improving the quality of content, data accuracy, and user-friendliness of the Bhumi ATR/BPN application. Aplikasi Bhumi ATR/BPN dikembangkan sebagai sistem informasi geospasial interaktif untuk mendukung transformasi digital layanan publik Kementerian Agraria dan Tata Ruang/Badan Pertanahan Nasional (ATR/BPN). Penelitian ini bertujuan untuk menganalisis kepuasan pengguna aplikasi Bhumi dengan menggunakan model End-User Computing Satisfaction (EUCS) yang mencakup lima dimensi: konten, akurasi, format, kemudahan penggunaan, dan ketepatan waktu. Pendekatan kuantitatif digunakan melalui penyebaran kuesioner terhadap 427 pengguna. Analisis regresi menunjukkan bahwa konten (β=0,237), akurasi (β=0,181), dan kemudahan penggunaan (β=0,292) berpengaruh signifikan terhadap kepuasan pengguna (p<0,01), sedangkan format dan ketepatan waktu tidak menunjukkan pengaruh yang signifikan. Kelima variabel secara simultan menjelaskan 46% variansi kepuasan pengguna (R²=0,460). Batasan penelitian ini terletak pada metode pengambilan sampel secara purposive dan convenience sampling, yang cenderung merepresentasikan pengguna aktif dengan akses digital yang baik. Hasil penelitian ini memberikan masukan bagi pengembangan sistem informasi sektor publik, terutama dalam peningkatan kualitas konten, keakuratan data, dan kemudahan penggunaan Bhumi Kementerian ATR/BPN.
