Abstract

One of the most common products grown by many in North Sumatra, especially Karo Regency, is coffee. This plant can bring in foreign exchange, making it a valuable plantation item in the Karo Regency's local economy. Despite the industry's high production and farmers' favorable experiences, soil erosion and water scarcity on agricultural land pose sustainability challenges. This occurs due to farmers needing more technical expertise or real-world post-harvest processing experience. Simultaneously, the Circular Economy (CE) notion is becoming more popular due to its capacity to improve sustainable development. By further utilizing waste to create an alternative product, this research aims to apply CE to the Karo coffee supply chain to increase sustainable elements, specifically social and economic, and lessen its environmental impact. Aside from that, utilizing the Soft System Methodology approach, adjustments must be made to policies or management practices in order to facilitate the deployment of CE. When implementing CE ideas in the agriculture supply chain, Soft System Methodology can help identify issues from the viewpoints of different supply chain actors. The investigation's findings indicate that there is a chance to apply CE to the Karo coffee supply chain. The rise in economic value resulting from utilizing and reprocessing the generated garbage into substitute items is evidence of this, with total sales increasing from Rp 1.130.400.000 to Rp 1.229.350.000 after CE implementation.

Abstract

Industry 4.0 has shifted business processes from traditional to digital systems and forced companies to take strategic steps to become more sustainable, one of which is e-commerce technology. A key element in getting consumers to accept and be interested in using e-commerce is the availability of a user-friendly e-commerce platform. This study intended to examine how the Technology Acceptance Model (TAM) theory's application analyzes consumer acceptability and adoption of the e-commerce website. The number of users that have completed transactions on the e-commerce (Plantage.id) website between January 2021 and August 2022 serves as the population and sample in this causal quantitative study. SEM-PLS, using the software SmartPLS, is used for data analysis. The results showed a positive and significant relationship between a significant relationship website; meanwhile, the influence of perceived ease of use on attitude towards using, perceived usefulness on behavioral intention, and attitude towards using on behavioral intention showed insignificant effects. The results of this study align with the Technology Acceptance Model (TAM) theory, which states that the perceived ease of use and perceived usefulness are the main factors that are important for users in determining the acceptance and actual usage of a new information technology system such as e-commerce. The higher these two factors, the greater the chance consumers can accept and use the systems.

Abstract

The economy was one factor the progress of a country. Each country competing to increase the productivity of the economy. Indonesia's economy ranks 17 world. Economic growth in Indonesia is very significant that was not separated from the role of small and medium enterprises (SMEs) that support the growth of exports and imports, one that can be seeded SMEs are SMEs manufacture of shoes. The role of SMEs that are so large and significant must always be maintained and developed to be able to compete in an era of global competition such as the implementation of the Asean Economic Community (AEC) in January 2015. Problems that interfere with the development and productivity of SMEs shoes, particularly around Medan city will be divided into 4 categories, namely: (1) human, (2) process, (3) facilities, and (4) Business competition. Based on this research, it is known that the most important issues that affect the development of SMEs in Medan shoe is its human resources. Solving these problems will be done with the Kaizen strategy (5S) which will be combined with the concept of training within industry (TWI) and the concept of P-Course. These improvements will result in strategies to increase the overall productivity of SMEs working with the primary focus is working and will evaluate the system works. This strategy is expected to fix the weaknesses of existing SMEs shoes, in order to face the global competition that will come.

Abstract

Technological developments in the industrial world encourage innovation in the inspection process, one of which is the application of artificial intelligence with machine learning. CV. XYZ is a palm oil machine component fabrication workshop that still applies manual quality inspection. Manual inspections are prone to errors, depend on human skills, and take a long time. This research aims to develop an automated inspection system using the YOLO (You Only Look Once) model which is a convolutional neural network (CNN) based algorithm for product defect detection. The manual inspection used is considered inconsistent, error-prone, and time-consuming. The use of machine learning is able to identify product defects such as geometry defect, porous defect, and surface defect. Evaluation of model performance using confusion matrix, loss graph, and precision recall curve. The results obtained show that the model has detection accuracy with a mAP50-95 value of 74.5%, mAP50 of 88.5%, and detection time of 0.0084 seconds per image.

Abstract

Supply chain resilience refers to the capacity of a supply chain to develop adequate responsiveness, readiness, and recovery strength so it can handle risks and disruptions and restore its operations to their previous condition or achieve an even better state. Bobabox faced challenges such as fluctuating sales, the closure of six outlets, shifting customer demand, and increasing competition. This study involved 81 boba drink outlets in Medan using purposive sampling. Data were collected through questionnaires and an interview with the Bobabox CEO, then analyzed using Smart-PLS 4 to test relationships between variables. SWOT and QSPM methods were applied to formulate strategies. The findings show that supply chain resilience significantly influences company performance. The IE matrix placed Bobabox in quadrant V (hold and maintain), suggesting that the company should preserve its current market position and focus on efficiency rather than aggressive expansion. The study identified 11 internal factors (IFE score: 2.73636) and 8 external factors (EFE score: 2.67857). The SWOT matrix produced nine alternative marketing strategies. Based on the QSPM results, the most recommended strategy is reducing supplier dependency through multi-sourcing to mitigate geopolitical risks (W2, T3).
