Abstract

The increasing energy demand in Indonesia, particularly from the industrial sector, has heightened the need to reduce reliance on fossil fuels by integrating new and renewable energy (NRE) sources into the energy mix. For the industrial sector, adopting NRE technologies presents options such as purchasing, manufacturing, or acquiring technology. This study focuses on selecting the most effective option for a small Vertical Axis Wind Turbine (VAWT), specifically the Tulip VAWT, by evaluating its hardware performance. The selection process utilizes subjective judgment and the Analytical Hierarchy Process (AHP), considering five key factors: installability, usability, affordability, availability, and maintainability. Results indicate that Technology Acquisition (TA) is the optimal choice, with an AHP score of 0.65, outperforming the purchasing options (0.322) and manufacturing options (0.296). These findings suggest that evaluating these five factors significantly impacts the decision-making process regarding adopting the Tulip VAWT. However, the study does not assess the effectiveness of the associated knowledge (software) or organizational factors, as no established methodology exists for this evaluation yet.

Abstract

The burgeoning of e-commerce industry especially instant delivery service provides new opportunities for warehousing companies such as PT. XYZ. However, demand for short time window in the handover process given to the warehouses is essential in the business. Piling carry-over order from previous day in combination with large incoming orders with uncontrollable user arrival time creates queues especially in the early opening hours with significant amount of the overall handover time. This research aims to develop a smart locker system tailor made for the handover purposes with fast access by the warehouse worker and simultaneous user access by scanning a dynamically generated QR Codes on each locker door. The Organic Light Emitting Diode (OLED) display could accurately show the QR Code and the locker doors could successfully open when the user scan the QR Code using the web apps. It is proven that the smart locker system could reduce the handover time with average of the package claiming time of 18.18 seconds reducing the overall handover time to below the desired 5 minutes by PT. XYZ warehouse management team.
