Abstract

The development of digital technology has driven the growth of online-based culinary businesses, including in the city of Pekanbaru. One of the players in this field is O Dimsum Pekanbaru, which utilizes social media to market its products without having a physical outlet. This study aims to analyze customer satisfaction levels toward O Dimsum’s products and services, as well as identify the factors that influence them. The research method used is a descriptive qualitative approach, with data collected through interviews with customers who have made purchases more than twice. The results show that, in general, customers are satisfied with the taste of the products, consistency of quality, reasonable pricing, as well as the speed and friendliness of the admin service during the ordering process. The hygienic and attractive packaging, along with effective promotion through Instagram, also contributes to strengthening customer satisfaction. However, there are some notes regarding delivery delays during peak hours, which require attention for future service improvements.

Abstract

The increasing volatility of the capital market driven by global economic uncertainty requires investors to select optimal investment options despite limited information. This study aims to analyze investment decision-making using three primary approaches under uncertainty: the Maximax, Maximin, and Minimax Regret methods. The data consist of historical returns from several large-cap stocks listed on the Indonesia Stock Exchange (IDX) over the past three years, which show substantial fluctuations. The analysis compares payoff values under different market conditions (optimistic, moderate, and pessimistic) and calculates regret levels to identify the most efficient investment alternative. The findings indicate that the Maximax method favors high-risk stocks with the highest potential returns, the Maximin method prioritizes stable defensive stocks, while Minimax Regret offers the most balanced decision by accounting for potential opportunity losses. Managerial implications highlight the importance of understanding investor risk profiles when formulating investment strategies and the need for financial institutions to provide uncertainty-based analytical tools. This study contributes to the investment decision-making literature in volatile markets by demonstrating the applicability of classical uncertainty decision models in generating adaptive and measurable investment strategies.
