Abstract

Artificial intelligence has emerged as one of the key drivers of innovation and sustainability in digital businesses. This study explores the impact of AI adoption on innovation and digital business sustainability in Indonesia, along with the moderating role of financial management in this relationship. The research uses Partial Least Squares-Structural Equation Modeling (PLS-SEM) with a purposive sample of owners and managers of digital businesses in Denpasar, Bali. Data were collected through structured questionnaires, then analyzed using SmartPLS 4.0. The findings indicated that AI adoption significantly enhanced innovation and digital business sustainability. Furthermore, financial management had a positive but relatively small moderating effect in enhancing the influence of AI on digital business sustainability. These results also signal that an appropriate AI investment strategy should be supported with relevant financial management in order to maximize all the benefits of AI. This study will be expected to provide a reference for digital business stakeholders, such as SMEs and startups, in the design of sustainable AI adoption strategies.

Abstract

This study aims to evaluate the production performance of Micro, Small, and Medium Enterprises (MSMEs) in rengginang production using the Quality Function Deployment (QFD) approach. Rengginang is a traditional Indonesian snack made from sticky rice, which has economic and cultural value but faces challenges in production consistency, hygiene, and capacity due to manual processing methods. The QFD method was applied to translate six key customer needs—such as production speed, hygiene, capacity, consistency, quality control, and product variation flexibility—into technical characteristics through the House of Quality (HoQ) matrix. Results showed that the most critical production need was achieving a drying process of no more than one day, followed by hygienic handling. These were translated into technical priorities such as high-speed drying machines and closed-drying systems. The relative weight analysis indicated that these technical improvements had a high impact on production performance with relatively moderate implementation complexity. This study provides MSME actors with a structured model to improve production efficiency and competitiveness based on customer-oriented planning. Keywords: Quality Function Deployment (QFD), House of Quality, MSMEs, Rengginang, Production Performance

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

Abstract

Let G=(V,E) be a simple and connected graph. The adjacency matrix G is a representation of a graph in the form of a square matrix, with the size of the matrix determined by the order G. By defining a graph into a matrix, lots of research related to a spectrum has been done by researchers. Later, they defined the anti-adjacency matrix as a matrix obtained by subtracting a matrix with all entries equal to one and the adjacency matrix G. In this paper, we determine the characteristic polynomial of matrix anti-adjacency for corona product between complete graph K_m and K_1and hyper-octahedral graph H_m and K_1 with the eigenvalues.
