The rapid development of Information Technology today brings ease of work in variousfields, such as mathematics. Complex calculations can be completed easily and quickly just by using acalculator. Calculations can also be done using an application program, where the application isdeveloped using a programming language. Of the many programming languages that exist today,including Java and VisualBasic. This research is a basic research where in this study an analysis of the programming language with matrix multiplication problems is carried out.The purpose oft his research is to see which programming language is better based on predetermined criteria. The research methodused is by analyzing the algorithms of the two programming languages with matrix multiplicationproblems based on relevant sources. The results showed that the Visual Basic is better than the Java based on these criteria.

Logistics business activities, expedition services and couriers are sectors that experienced a growth spurt and even showed an increase in transaction value. PT. Asia Pacific Dirgantara (Aspac Cargo) is an expedition service company that requires a mechanism in the distribution of goods. In the distribution of goods, planning to determine shipping costs is very influential. Good planning makes PT. Aspac Cargo is superior to other shipping companies so that it can get maximum profit. The purpose of this study was to determine the minimum cost of shipping goods at PT. Aspac Cargo using the Zero Suffix method and the minimum cost percentage obtained by PT. Aspac Cargo in minimizing the cost of shipping goods using the Zero Suffix method. This research is applied research and the data used are data on delivery of goods, data on demand for delivery of goods and data on the cost of shipping goods from the city of origin to the city of destination. The final result of the application of the Zero Suffix method to minimize the cost of shipping goods at PT. Aspac Cargo is Rp. 322,322,000 and the percentage of the minimum cost obtained by PT. Aspac Cargo in minimizing the cost of shipping goods using the Zero Suffix method, which is 16.9%

COVID-19 has spread and has become a pandemic in almost all of the world, including in Indonesia. In Indonesia, this virus was first announced on March 2, 2020, until March 14 to 27, 2020, a total of 77,261 cases were identified. In an effort to stop the spread of COVID-19, the Indonesian government has made several policies that are expected to suppress the spread of this virus. Cluster analysis is a technical class, used to classify objects or cases into relatively homogeneous (same) groups called clusters. The type of data used is secondary data on COVID-19 in districts/cities of West Sumatra Province obtained from the West Sumatra Provincial Health Office and the COVID-19 task force website, where the data obtained is cumulative data from March 2020 to July 14, 2021. Optimization the number of K clusters using the elbow method to produce K=3, the results of the K-means cluster analysis with the number of K=3 concluded that the distance of members in the cluster is low and the distance between clusters is large

ABSTRACT Online compulsive buying disorder is a disorder of impulse control when shopping online, so that a person becomes uncontrollable when shopping online and is done repeatedly with a large number of purchases and not so useful. The purpose of this study is to analyze the mathematical model of the spread of online compulsive buying disorder. The method used is the descriptive method. Based on the analysis of the mathematical model of the spread of online compulsive buying disorder, one equilibrium point was obtained, where all eigenvalues of the Jacobi matrix were negative, so that the equilibrium point of the mathematical model of the spread of online compulsive buying disorder was stable asymptotic. This suggests that the spread of online compulsive buying behavior will go towards the equilibrium point over time.
