Abstract

Perkembangan teknologi informasi menuntut lembaga pendidikan untuk mengoptimalkan layanan administrasi berbasis digital, namun proses Penerimaan Peserta Didik Baru (PPDB) di SMAS GKPI Padang Bulan masih dilakukan secara manual sehingga menimbulkan keterbatasan akses informasi, keterlambatan pengolahan data, dan kurangnya transparansi. Penelitian ini bertujuan untuk mengidentifikasi permasalahan pada sistem PPDB yang berjalan serta merancang dan mengimplementasikan sistem informasi pendaftaran siswa baru berbasis web guna meningkatkan efisiensi administrasi. Penelitian menggunakan pendekatan Research and Development dengan teknik pengumpulan data melalui studi literatur, observasi, dan wawancara, serta metode pengembangan perangkat lunak model waterfall yang meliputi tahap analisis kebutuhan, desain, pengkodean, pengujian, dan pemeliharaan. Hasil penelitian menunjukkan bahwa sistem yang dikembangkan menggunakan PHP dan MySQL mampu mengotomatisasi proses pendaftaran, menyimpan dan mengelola data secara terstruktur, serta mempermudah penyajian informasi secara real time. Implementasi sistem ini meningkatkan efisiensi kerja administrasi, akurasi pengolahan data, serta transparansi layanan kepada calon peserta didik dan orang tua. Secara implikatif, penelitian ini mendukung transformasi digital tata kelola pendidikan tingkat menengah dan dapat menjadi model pengembangan sistem PPDB berbasis web pada institusi pendidikan dengan karakteristik serupa.

Abstract

Cryptocurrency trading is a very popular business of buying and selling digital money today. Many investors trade cryptocurrency assets through cryptocurrency exchange platforms in the hope of getting a large profit difference. However, the cryptocurrency trading business is not always favourable for investors as choosing the wrong cryptocurrency exchange can result in huge losses from the trades made. Based on these problems, it is necessary to have a decision support system for selecting the most relevant cryptocurrency exchange to be used as a cryptocurrency trading platform that can increase the chances of investors making profits. The decision support system method used in this research is Preference Selection Index (PSI). The results of the selection of cryptocurrency exchanges using the Preference Selection Index (PSI) method in this study recommend Indodax as the most relevant cryptocurrency exchange used by investors to gain profits in running a cryptocurrency trading business because it gets the highest value (0.893662729) compared to 4 other alternatives.
