Abstract

The Indonesian Red Cross (PMI) is an independent and neutral organization in Indonesia engaged in humanitarian activities. One of the departments within the Indonesian Red Cross is the blood donor unit. The Blood Donor Unit (UDD) of PMI Deli Serdang is one of the Indonesian Red Cross offices in the Deli Serdang district, which deals with social humanitarian activities such as blood donation, volunteer recruitment, emergency response, and others. One common issue in blood distribution is the numerous routes that need to be taken, resulting in wasted time and delayed blood deliveries. Due to this issue, the implementation of artificial intelligence is needed to determine the shortest route for optimal and fast blood delivery. The application of artificial intelligence in problem-solving in the field of computer science has seen rapid development over the years in line with the advancement of artificial intelligence itself. In determining the shortest route, several algorithms can be used, one of which is the Dijkstra algorithm. It is used to solve problems in a graph to determine the shortest route. In the process, the Dijkstra algorithm determines the points that will become the distance weights connected from one point to another, resulting in the desired nodes. Therefore, an application is needed to find the nearest route to make blood delivery more time-efficient. In manual calculations using the algorithm, it was found that the shortest route from UDD (PMI Deli Serdang Blood Donation Unit) to GM (Grand Medistra Hospital) is through the route UDD → A → B → C → D → GM = 0 + 300 m + 250 m + 1,500 m + 35 m + 90 m with a total distance of 2,175 meters or 2.1 kilometers in 5 minutes. Thus, the use of the Dijkstra algorithm can assist in determining the fastest and optimal route for blood distribution, saving time and improving delivery efficiency.

Abstract

The Indonesian capital market plays an important role in supporting national economic growth, particularly through stock investments. Blue-chip stocks are considered stable and have the potential to provide long-term returns, yet selecting the right ones remains a challenge for investors. This study aims to develop a recommendation system for selecting blue-chip stocks on the Indonesia Stock Exchange (BEI) using the Fuzzy Mamdani method. The research data were collected from a set of actively traded blue-chip stocks within a specific period and analyzed using four main variables: stock price, trading volume, market capitalization, and financial ratios. The recommendation process involves fuzzification, the formulation of 15 rule bases established through expert consultation with market analysts, Mamdani inference, and defuzzification to produce recommendation scores. The implementation results show that the system achieved an accuracy level of 84.65%, indicating stable consistency with actual market conditions. These findings confirm that the Fuzzy Mamdani method is effective in generating objective and systematic recommendations for blue-chip stock selection. The developed system successfully meets the research objective by assisting investors in identifying suitable stocks based on data-driven analysis.
