Abstract

This research investigates the impact of external factors on stock prices by analyzing historical data from Yahoo Finance. The study aims to comprehensively examine how global events, international news, and macroeconomic indicators influence stock market dynamics. Utilizing a mixed-method approach combining quantitative time series analysis and qualitative event study methodology, we analyzed stock price movements across multiple sectors during significant global events between 2018-2023. The research employed advanced statistical techniques including multiple regression, event study methodology, and correlation analysis to identify and quantify the relationship between external factors and stock price variations. Results demonstrated that geopolitical events, economic policy changes, and international health crises significantly influence stock price volatility, with correlation coefficients ranging from 0.65 to 0.85 across different market sectors. The study provides crucial insights for investors, policymakers, and financial analysts in understanding the complex interplay between external factors and stock market performance.

Abstract

Pengelolaan arsip surat secara manual pada instansi pemerintahan sering menimbulkan berbagai kendala, seperti keterlambatan pencarian, risiko kehilangan dokumen, serta kurangnya integrasi data. Penelitian ini bertujuan mengembangkan sistem informasi berbasis website untuk mengelola arsip surat masuk dan keluar di Dinas Kependudukan dan Pencatatan Sipil (Disdukcapil) Kabupaten Nias. Sistem ini dirancang menggunakan model pengembangan perangkat lunak Waterfall, melalui tahapan analisis kebutuhan, perancangan, implementasi, pengujian, dan pemeliharaan. Data diperoleh melalui observasi, wawancara, dan studi literatur. Sistem yang dibangun terdiri dari tiga level pengguna: Super Admin, Admin, dan User, dengan hak akses yang disesuaikan. Fitur utama meliputi pengelolaan surat masuk/keluar, pencatatan otomatis, disposisi, pelacakan status surat, serta penyajian laporan berkala. Hasil implementasi menunjukkan peningkatan efisiensi administrasi, akurasi data, serta transparansi layanan publik. Sistem ini tidak hanya menyelesaikan permasalahan arsip di Disdukcapil Nias, tetapi juga berpotensi menjadi model penerapan digitalisasi arsip bagi instansi pemerintahan lainnya. Penerapan sistem ini mendukung transformasi digital dalam pengelolaan administrasi publik yang lebih efektif dan modern.
