Abstract

Food stalls are one form of culinary business that faces challenges in managing limited raw materials to maximize profits. This study uses a linear programming method with a Simplex approach to optimize the profits of Solo food stalls that sell three main menus: fried rice, fried noodles, and meatballs. The optimization model is designed by considering the limitations of raw materials such as vegetables, eggs, chicken, oil, sauce, and spices, as well as the selling price and cost of raw materials per portion. In this case, we use manual and software analysis, namely by using POM-QM for Windows. The results of manual and software analysis show the same results, namely by producing 25 additional packages of fried rice and 33.33 packages of meatballs. Because the requested results use integer numbers, we perform branch and bound analysis to produce the maximum value with all values ????of x1, x2, x3 are decimal numbers. The optimization results show that the Simplex method can determine the combination of the number of portions of each menu optimally to achieve maximum profit without violating resource constraints. Thus, this article was created so that we can determine the maximum profit with the availability of existing raw materials and with the capacity that traders have to make it easier for traders to manage.

Abstract

 Indonesia is an agrarian country with great potential in the agricultural sector, particularly in key commodities such as rice and corn, which play an important role in food security and animal feed. However, limited resources such as land, fertilizer, and labor pose challenges in achieving production efficiency and maximum profits. This study aims to optimize agricultural land allocation to maximize profits using a linear programming model. The case study was conducted on agricultural land owned by a resident of Bajo Village, Bima Regency, West Nusa Tenggara. Primary data was collected through direct interviews, including land area, input requirements (fertilizer, pesticides, herbicides, and labor), and profit per hectare. The model was solved using the graphical method with the assistance of POM-QM for Windows and Google Colab application. The analysis results indicate that the optimal land allocation is 3.65 hectares for rice and 2.54 hectares for corn, yielding a maximum profit of Rp58.906.350,00. This solution meets all available resource constraints. These findings indicate that the linear programming approach is effective in helping farmers make data-driven decisions to improve land and resource management efficiency. The application of this model also opens opportunities for the implementation of similar methods in other sustainable agricultural planning, particularly in the context of small-scale agriculture with limited resources.

Abstract

Geometry is one of the fundamental topics in mathematics, playing a crucial role in understanding shapes, sizes, positions, and spatial relationships between objects. Mastery of this concept is essential; however, in practice, many students still struggle to grasp geometry material. This issue is also evident at SMA Negeri 1 Pujut, where several students demonstrate a low level of understanding of geometric concepts. In response to this problem, the aim of the research is a community service activity was carried out in the form of tutoring sessions focused on improving students' understanding of geometry. This activity employed a visualization approach through function graph sketches to help students better comprehend the interconnections between concepts in a more concrete way. Based on the evaluation results, data showed that 86.67% of students exhibited improved learning outcomes after participating in the activity. This achievement indicates that the instructional method used by the facilitators was quite effective and well-received by the majority of participants.

Abstract

This article discusses community service through the Teaching Campus Program at SDN 4 Mataram with the aim of improving the quality of student learning. This program was chosen due to the challenges of improving the quality of education at the primary level which still requires innovative interventions. The method applied involves students as facilitators in supporting teachers, developing lesson plans, and developing interesting learning media. Evaluation is conducted through tests and observations to measure student progress. The results show significant improvements in student motivation and understanding, as well as students' ability to apply educational theory in the field. The program also strengthened the relationship between the school and the academic community. In conclusion, collaboration between higher education institutions and elementary schools through the Teaching Campus Program has a significant positive impact on the quality of learning and competency development of the various parties involved.
