Abstract

Matrix is one among math subjects which are considered hard. Matrix is considered hard mainly because there are so many calculations needed to be done. Because of the same reason, finding faults in the calculations is also hard, which makes the learning process that mainly consists of exercises harder. To overcome that, a matrix calculator software which can show the calculation steps was developed. The development produced prototype model which has five main features, which are elementary row operation helper, basic matrix operation calculator, matrix form calculator, matrix determinant calculator using Laplace expansion, and a solver for linear equations using Cramer’s rule. The application had been tested with black box testing for its functionality which shows that every feature was working properly. However, this application has not been tested for its effectivity, so it is still considered a prototype.

Abstract

Blockchain has been the hype in technology lately and supply chain management is often mentioned as one of its applications. However, it is unwise to just eat the hype. Blockchain does have weaknesses; some of its natures considered as strengths might be weaknesses or problems in some cases. There are many things to be considered and among them are the challenges. This paper presents a systematic literature review of challenges in using blockchain for supply chain management information systems. This paper aims to help stakeholders and top management of supply chains when considering on adopting blockchain. The literatures were gathered from open-access papers found on Google Scholar. A total of 76 unique papers were found and then 29 were selected. The findings were classified into 12 categories. The top three category of challenges are development and implementation, performance and efficiency, and sustainability and scalability. Apparently, although blockchain in cryptocurrency is pretty solid, there are many challenges in its usage for supply chain.
