Abstract

Applied mathematics plays an important role in solving real-world problems, including in the agricultural product processing industry. This study aims to apply the Modified Ghadle-Munot method to solve employee assignment problems in a private company operating in chocolate production and to connect its implementation with applied mathematics learning. The core issue addressed is the imbalance between the number of employees and the number of production stages, which creates an unbalanced assignment problem. This study uses an applied quantitative research approach with assignment optimization as the main variable. Data were collected through interviews and documentation related to the production process and employee task distribution. The results showed that the Modified Ghadle-Munot method was able to reduce the total work time from an initial average of 970 minutes to 660 minutes. The application of this algorithm not only improves operational efficiency but also carries educational value. It can serve as a contextual case study in teaching applied mathematics, particularly in linear programming and optimization. Therefore, this research contributes both to practical problem-solving in small-scale industry settings and to strengthening real-world, problem-based learning in mathematics education.

Abstract

The Lagosi motif, a prominent design in the traditional fabric of the Wajo district, is well-known but increasingly rare among local weavers. This motif, drawing inspiration from natural elements such as flowers and stems, holds significant philosophical and cultural meaning for the Wajo people, serving as a key element of their endangered cultural heritage. Despite its cultural importance, the motif has been minimally explored in the context of ethnomathematics. Consequently, this study investigates the mathematical concepts inherent in the design of Lagosi motifs, aiming to utilize them as educational tools for students and to support cultural preservation efforts. Employing a qualitative research methodology with an ethnographic approach, data were collected through observations, interviews, and documentation. The validity and reliability of the data were ensured through triangulation and confirmability. The study reveals that geometric transformations, specifically translation and reflection, play a central role in the creation of Lagosi motifs. These findings highlight the natural emergence of mathematical concepts within local cultural practices, offering potential for their integration into contextualized mathematics education. Furthermore, the results aim to instill a sense of cultural pride in students, thereby contributing to the preservation of Wajo's cultural heritage. The study also underscores the opportunity to leverage Lagosi motifs as culturally relevant educational tools and to foster interdisciplinary collaboration between mathematics and cultural studies.

Abstract

Abstract:This study uses transportation methods to optimize the distribution cost of staples from Parepare City to Sidrap, Barru, Pinrang, and Bone City in South Sulawesi. The three transportation methods used in this study were Least Cost (LC), Vogel's Approximation Method (VAM), and North West Corner. The data used is in the form of transportation cost data from Parepare to the four cities. The calculation results with Vogel's Approximation Method (VAM) model provide more optimal results by maximizing the delivery from the 3rd warehouse to the Sidrap, Barru, and Pinrang. These findings provide information on optimal transportation methods to save distribution costs. Abstrak:Penelitian ini menggunakan metode transportasi untuk mengoptimalkan biaya distribusi bahan pokok dari Kota Parepare ke Kota Sidrap, Barru, Pinrang, dan Bone di Sulawesi Selatan. Tiga metode transportasi yang digunakan pada penelitian ini adalah Least Cost (LC), Vogel’s Approximation Method (VAM), dan North West Corner. Data yang digunakan berupa data biaya transportasi dari Parepare ke empat kota tersebut. Hasil perhitungan dengan model Vogel’s Approximation Method (VAM) memberikan hasil yang lebih optimal dengan memaksimalkan pengiriman pasokan barang dari gudang ke-3 ke Kota Sidrap, Barru, dan Pinrang. Temuan ini memberikan informasi penggunaan metode transportasi yang optimal untuk menghemat biaya distribusi.

Abstract

The purpose of this study is to explain the doctrine expectations of learning mathematics. Data was collected through testing, interviews, and documentation. Researchers have designed a virtual learning trajectory (HLT) based on examining the obstacles students face when learning mathematics. Next, a didactic design was developed from HLT. The method of doctrine was implemented, and the results showed that the situation of the three principles expected by researchers was the doctrine of scaffolding strategy. When determining values ​​that correspond to a pattern of numbers, researchers want to learn lessons and provide instructions in the form of education to solve problems. The researcher's expectation of giving other examples of arithmetic progressions when choosing a definition and the arithmetic progression examples help students better understand collaborative learning. The value of the nth term and the sum of the first n math terms are sent to each shirt to confirm the work and interact directly.
