Artikel ini memuat analisis hubungan antar variabel perdagangan saham yakni volume perdagangan, bid-ask spreads, dan volatilitas return saham dalam ruang lingkup dua hipotesis utama yakni the mixture of distribution hypothesis (MDH) dan the sequential information arrival hypothesis (SIAH). Hasil perhitungan mengidentifikasi bahwa pada sebagian besar saham terdapat hubungan kontemporer positif antara volume perdagangan terhadap voltilitas return tidak cukup bukti mendukung teori MDH.

This research explores the causality model between trading volume, bid-ask spread, and stock return volatility in the business index-27. Utilizing historical data, Granger causality analysis is employed to determine the direction and strength of the relationships between these variables. The findings reveal significant causal relationships among trading volume, bid-ask spread, and stock return volatility. These findings offer valuable insights into understanding stock market dynamics and their implications for investment decision-making. Moreover,This article contains an analysis of the relationship between stock trading variables within the scope of two main hypothesis namely the mixture of distribution hypothesis (MDH) and the sequential information arrival hypothesis (SIAH). The calculation results identify that for most stocks there is a one way Granger causality relationship between trading volume and return volatility, which is not sufficient evidence to support the MDH theory.

Manual legalization of academic documents often leads to various issues such as long queues, slow processing times, and a lack of transparency in application status, especially for alumni who live far from campus. This makes it even more difficult for alumni due to transportation and accomodation issues. This study aims to design and develop an online legalization service system integrated with a payment gateway and delivery services to facilitate the legalization process for alumni. The system is developed using the Laravel framework and MySQL database, and integrates digital payment services via Midtrans and document delivery through Biteship as logistic aggregators. The result of this research is a web-based online legalization service system that allows alumni to submit legalization requests, make online payments, and choose document delivery options to their destination address. System testing shows that all features run well and can improve efficiency and user convenience in managing document legalization. Thus, this system can be a digital solution that supports faster, more transparent, and accessible academic administrative services.
