Abstract

In today's business competition, educational institutions or courses require optimizing profits. However, this is not easy because, in its implementation, there are many priority objective functions that must be fulfilled. In this case, the course institution has different class programs, namely literacy, numeracy, and math olympiad programs, with various operational costs per program type and course fees per program type. This problem requires setting priorities because of the limited number of revenues, operating costs, and profit targets. In this paper, the researcher uses Winter's Exponential Smoothing forecasting model to determine the number of students, operating costs, and profits in the following year. Then the researcher analyzes the planning with the goal programming method to minimize the deviation of the multi-objective programming. This research shows that the number of student admissions who can meet market demand for January 2021 decreased by 5.41%, in February decreased by 3.20%, in March decreased by 1.29%, April remained constant, in May increased by 1.44%, June increased by 2.16%, July increased 2.82%, August increased 2.78%, September increased 3.47%, October increased 3.22%, November an increase of 3.33%, and for December an increase of 2.69%. The total operational cost that does not exceed the target limit is Rp. 30,475,0000 for one year. The total profit has reached the target to be achieved, which is Rp. 322,150,000 for one year.

Abstract

The Polynomial Combinatorics comes from optimization problem combinatorial in form the nonlinear and integer programming. This paper present a condition such that the polynomial combinatorics has solution. Existence of optimum value will be found by restriction of decision variable and properties of feasible solution set or polyhedra.

Abstract

The arrangement of selfie photo spots is expected to increase the target of tourist visits, both foreign and local. Therefore, making selfie photo spots will be used as a promotional medium to increase the number of tourist visits. Sweembath Bahapal baths were built in 1930 by the Dutch government by employing plantation workers. The results of the preliminary survey indicate the need for further development so that it is expected to improve the welfare of the village community. The purpose of the activity is to become a creative and attractive place for recreation with an environmental perspective, organizing selfie photo spots which are expected to increase the target of tourist visits, both foreign and local. The method used in the implementation of the construction of eight selfie photo spots is something that provides recreational facilities that can make tourists active in tourist activities, the University of North Sumatra community service agency builds facilities for self-painted photo spots as follows (1) Dolphins, (2) Dinosaurs, (3) Elephants, (4) Butterflies, (5) Fire Tongue Wings, (6) Whales, (7) Butterflies, and (8) Turtles. Spot facilities Selfie photos form facts in the form of responses from collective or individual subjects such as 1) the presence of visitors who take advantage of the facilities, 2) parking attendants who regulate vehicle parking 3) traders who sell types of merchandise products, 3) place rental, mats, buoys, and changing rooms. The impact of the development and improvement of the functions of the facilities and infrastructure above, affects the welfare of the community, managers and traders in the Sweembath environment.

Abstract

Robust optimization is based on the assumption that uncertain data has a convex set as well as a finite set termed uncertainty. The discussion starts with determining the robust counterpart, which is accomplished by assuming the indeterminate data set is in the form of boxes, intervals, box-intervals, ellipses, or polyhedra. In this study, the robust counterpart is characterized by a box-interval uncertainty set. Robust counterpart formulation is also associated with master and subproblems. Robust Benders decomposition is applied to address problems with convex goals and quasiconvex constraints in robust optimization. For all data parameters, this method is used to determine the best resilient solution in the feasible region. A manual example of this problem's calculation is provided, and the process is continued using production and operations management–quantitative methods (POM-QM) software.

Abstract

In general, junior high school students view mathematics as a difficult and boring subject. In addition to students, teachers also experience difficulties in delivering material, including time constraints in delivering quite a lot of material, and a lack of student interest in learning mathematics when using conventional learning methods such as from textbooks and explanations from the teacher. With these considerations, the proposer wants to apply knowledge and technology by making mathematics learning media tutorials so that they can increase understanding and attract students' interest in learning and help improve the quality of mathematics education and teaching. The result achieved is that community service for active learning and ICT should be reproduced because there are still many schools that have not implemented it. Meanwhile, from the progress of the times, namely Industry 4.0, ICT-based learning is very much needed.
