Abstract

Goal Programming is a method of solving problems by allocating company resources with several objectives to obtain an optimal solution. The solution can be obtained by using the QM for Windows program. The results showed that the objective function could be achieved well. The solution to the problem obtained from the QM For Windows application was that the optimal value for the budget cost of the window, storefront, and wardrobe raw materials was the same as the budget cost that had been issued by the furniture production owner, which was Rp. 22,850.000,00 per month. Then the upper limit can be minimized to raw material from aluminum (b1), which was 28.1 meters from the original 610 meters. In order to reach the target of the production process, the average working hours was 55 hours. For a good and correct production volume recommendation, the number of products produced must be optimal to produce 20 units of products consisting of 10 units of windows, five units of show windows, and five wardrobe units per month.

Abstract

Ethnomatematics is mathematics that is found in the culture of people who have unknowingly implemented mathematical concepts in their culture. The purpose of this qualitative research with an ethnographic approach is to describe ethnomathematics in the Barong Kemiren Art. The subjects of this study were three people, namely the head of the Barong Kemiren Arts, cultural observers who understand the history of the Barong Kemiren Arts and the dancers of the Barong Kemiren. Data collection methods used are observation, interviews, and documentation. The results of this study indicate that there is ethnomathematics in the Barong Kemiren Art. The geometric elements found include: flat shapes (triangles, squares, rectangles, and circles), spatial shapes (cubes, blocks, and tubes), congruence, and geometric transformations (reflections). Ethnomathematics in this study will be made worksheets with congruences material for class IX.
