Abstract

Optimasi merupakan suatu langkah untuk memperoleh penyelesaian yang terbaik dari suatu permasalahan. Dalam menyelesaikan suatu kasus optimasi, biasanya dibutuhkan kajian terkait pemrograman linear ataupun pemrograman integer. Contoh aplikasi dari pemrograman linear dan pemrograman integer adalah masalah transportasi, Vehicle Routing Problem, dan Traveling Salesman Problem. Banyak contoh kasus yang dapat dikaitkan dengan Traveling Salesman Problem. Salah satunya adalah pengantaran air minum isi ulang. Berdasarkan hal tersebut, tujuan penelitian ini adalah menentukan rute pengiriman optimal dalam pengiriman air minum isi ulang dengan menggunakan metode Nearest Neighbor.

Abstract

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.
