Abstract

Dosir adalah kumpulan berkas mengenai data kepegawaian mulai dari pemasukan surat lamaran sampai ditetapkan sebagai pegawai di perusahaan. Sistem pengelolaan arsip dosir pegawai di PT. PLN (Persero) wilayah Suluttenggo saat ini belum terkelola dengan baik. Hal ini dikarenakan belum adanya arsip atau media penyimpanan data sementara untuk menyimpan data tersebut agar tidak hilang atau rusak. Oleh sebab itu dibuat sebuah perangkat lunak yang dapat menyimpan data tersebut yang bisa berfungsi sebagai arsip elektronik. Dalam penelitian ini menggunakan pendekatan extreme programming model. Dalam extreme programming terdiri dari beberapa tahap, seperti tahap perencanaan, desain, pengkodean dan pengujian. Hasil pengimplementasian menggunakan model ini adalah untuk meningkatkan kualitas perangkat lunak dan tanggap terhadap perubahan kebutuhan pengguna.

Abstract

Abstract Tourism plays a vital role in driving economic growth, and Minahasa holds strong potential to optimize this sector. However, challenges remain in digital advertising, particularly regarding transparency and consumer trust. This study investigates the impact of blockchain technology on transparency, trust, and the effectiveness of digital advertising in Minahasa’s tourism industry. A quantitative explanatory design was employed using Partial Least Squares Structural Equation Modeling (SEM-PLS), with data collected from 150–250 respondents through purposive and snowball sampling techniques.The findings reveal that blockchain significantly influences all key variables. It enhances advertising transparency (T-statistic = 36.738, p = 0.000), strengthens consumer trust (T-statistic = 33.164, p = 0.000), and improves advertising effectiveness (T-statistic = 28.400, p = 0.000). These results highlight blockchain’s capacity to provide immutable records, ensure data authenticity, and optimize ad performance through verifiable real-time information. This study confirms that blockchain can serve as a strategic tool to promote transparent, trustworthy, and effective digital advertising in tourism. The findings provide practical insights for tourism stakeholders and contribute to academic discussions on technology-driven marketing innovation.
