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

Manual management of letter archives in government agencies remains a barrier to efficient administrative services. The main problems faced are delays in document retrieval, the risk of losing physical archives, and the lack of a tracking system and data integration between departments. This study aims to develop a website-based information system for incoming and outgoing letter archives at the Population and Civil Registration Office (Disdukcapil) of Nias Regency. This system is designed to replace manual processes and improve the effectiveness of agency archive management. The method used is the Waterfall software development model, with stages of needs analysis, system design, implementation, testing, and maintenance. Data collection techniques were carried out through direct field observation, interviews with related employees, and literature studies relevant to digital archiving systems. Analysis was carried out on user needs, business processes for letter management, and testing of the developed system's functionality. The results of the study indicate that this system can speed up the process of recording and tracking letters by up to 50%, reduce the risk of document loss, and improve data accuracy and transparency of disposition. With classified login features, automatic notifications, and digital reporting, this system is considered effective in supporting administrative modernization. The system developed also has the potential to be replicated in other government agencies to encourage digital transformation in public services.

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.
