Abstract

The development of the world globally in various fields of life has demanded intense competition. Therefore, every individual who inhabits this world needs to have certain competencies in order to be able to compete in this globalization era. Hence, each individual must be able to think at a high level (higher order thingking / HOT) especifically on math subjects. But the problems that occur, there are still many students who have difficulty in solving the problems in the form of higher order thinking (HOT) so that they have not been able to compete globally. To overcome this problem the researcher carried out a higher order thingking analysis on Algebraic material. This study aims at describing the analysis of higher order terms in Algebraic material. The method used were a test and interview of 3 informants in six schools based on students' levels of ability, namely high ability, moderate ability and low ability. The results showed that there were differences in solving HOT problems in students who had high, medium and low abilities.

Abstract

This study aims to find out how to optimize the cost of distribution t ahu, with the Nort West Corner method and the Stepping Stone method in t ahu Berika companies. To find out how distribution costs compare before and after conducting research on tahu Berika companies. The transportation method is one of the methods used to find the cheapest way to distribute products from several sources (distribution centers, warehouses) to several destinations so that total transportation costs are minimized. The conclusions obtained from this research are as follows: The cost of distributing tofu using the Nort West Corner method as an initial solution for Berika tofu companies in March 2023 is; while the cost of distributing tofu using the Stepping Stone method as the final solution to Berika tofu companies in March 2023 is by using the Nort West Corner method as the initial solution and the Stepping Stone method as the final solution, the total minimum distribution costs obtained by each of them are  and while the calculations made by the company know Berika before using the Nort West Corner method and the Stepping Stone method are as large as.  With the savings in distribution costs of each is as large as and
