Abstract

In 2021, the amount of blood production by the Indonesian Red Cross was higher than the existing needs. This can result in wasted blood bags. The availability of abundant blood bag supplies is not balanced with access to information on the availability of these blood bags. This study aims to build a smart logistics system that can provide information on the availability of blood bags in real-time. This study utilized a quantitative and explorative approach and employed the waterfall Software Development Life Cycle (SDLC) method using PHP and the CodeIgniter 3 framework, which was integrated with IoT devices such as sensors and GPS for real-time monitoring. In addition, this system will provide a tool to predict the number of donors needed, as well as estimate the number of donor quotas required during upcoming blood donation activities. This study has succeeded in developing a blood donor information system that adopts the smart logistics concept to control blood bag stock. The resulting system is capable of reducing the risk of shortages and obsolescence while enhancing synergy among stakeholders. The design of a system that facilitates openness of information on the level of blood needs and simplification of the donor system is expected to increase community responsibility in creating sustainable blood supply availability.

Abstract

This study aims to address challenges in the material procurement process within the steel fabrication industry, which currently relies on a manual, Excel-based system. Such a system is prone to data errors, delivery delays, and ineffective interdepartmental communication. The research employs a case study approach, incorporating direct observations, historical data analysis, and interviews with relevant stakeholders. The proposed solution is an integrated Vendor Managed Inventory (VMI) system, developed using the Waterfall model through stages ranging from requirements definition to system testing. Findings reveal that implementing the VMI system significantly enhances efficiency, transparency, and the speed of material procurement while improving collaboration between the company and its suppliers. Additionally, the system optimizes inventory management, reduces operational risks, and offers a scalable solution for various manufacturing sectors. In conclusion, the integrated VMI system contributes substantially to improving overall supply chain performance. Keywords: Efficiency, Integration, Inventory Management, Procurement, VMI System
