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: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.

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.

Students in the Mathematics Education Department at IAIN Parepare face substantial challenges in understanding and constructing proofs in Real Analysis due to limited familiarity with proof models, deductive principles, and the formal structures that underpin mathematical arguments. The absence of supporting courses such as Mathematical Logic further restricts their ability to read proof structures and interpret essential symbolic forms, including definitions involving ε–δ. This study developed the S-GeaR (Starting Point, Goals, Idea, References) strategy as a proof-investigation framework designed to guide students in systematically analyzing and reconstructing theorem proofs. Using the ADDIE development model, S-GeaR was designed, validated, and implemented through theorem investigation, collaborative discussions, and structured proof worksheets. Data were collected through tests, classroom observations, and student reflections. Quantitative results show an increase in scores from 58.2 to 76.4. Through the use of S-GeaR worksheets, students demonstrated gradual development in proof-related activities: recognizing proof methods, generating ideas and composing a complete formal proof. Qualitative findings also indicate that the procedural guidance of S-GeaR reduces cognitive load through component mapping and supports the emergence of proof ideas. These results underscore the important role of S-GeaR in strengthening students’ reasoning structure in theorems proofs.

Indonesia terkenal dengan beragam kebudayaan yang dimiliki. Salah satu dari kebudayaan tersebut adalah kain tenun yang tersebar di beberapa wilayah di Indonesia, termasuk kain tenun rongkong yang berasal dari daerah pegunungan di Kabupaten Luwu Utara Provinsi Sulawesi-Selatan. Penelitian ini bertujuan untuk mengeksplorasi etnomatematika yang ada pada kain tenun Rongkong khususnya pada motif Rundun Lolo. Penelitian ini merupakan penelitian kualitatif dengan pendekatan etnografi. Subjek pada penelitian ini adalah masyarakat Rongkong yang masih menekuni usaha tenun kain Rongkong sebanyak dua orang. Pengumpulan data dilakukan melalui studi pustaka, observasi, wawancara, dan dokumentasi yang selanjutnya dianalisis dengan teknik reduksi data, penyajian data dan menarik kesimpulan. Hasil penelitian menunjukkan bahwa: 1) etnomatematika dalam proses pembuatan kain tenun Rongkong motif Rundun Lolo adalah geometri bidang datar yang berupa segitiga, belah ketupat dan jajar genjang 2) etnomatematika pada kain tenun Rongkong motif Rundun Lolo adalah transformasi yang terdiri atas pencerminan atau refleksi dan geseran atau dilatasi 3) etnomatematika pada proses pembuatan kain tenun Rongkong motif Rundun Lolo adalah skala dan perbandingan.

This study examines the integration of hadith with the local cultures of the Bugis, Makassar, and Mandar communities in the Islamization of South Sulawesi. Unlike previous research that predominantly focuses on the historical or political dimensions of Islamization, this study highlights how the core principles of the Prophet Muhammad’s da‘wah—particularly gentleness (rifq), ease (taysīr), wisdom (ḥikmah), and gradualism (tadarruj)—were translated by early scholars into culturally resonant practices. Employing a qualitative descriptive approach, this research analyzes hadith texts, historical sources, ethnographic studies, and empirical data from the da‘wah practices of influential figures : Datuk ri Bandang, Datuk Patimang and Datuk ri Tiro. The findings reveal that Islam was embraced peacefully due to the deep compatibility between Prophetic ethical principles and local cultural values such as siri’ (honor), pacce (solidarity), and sipakatau (human dignity). This harmony is reflected in the Islamized forms of communal traditions, including mabbarazanji, sayyang pattu’du, and other ritual expressions. The study concludes that the success of Islamization in South Sulawesi resulted from adaptive, persuasive, and context-sensitive da‘wah strategies rooted in the Sunnah. These findings offer a compelling model of hadith-based cultural da‘wah that remains highly relevant for contemporary multicultural societies.

This study aims to apply the Hungarian method to the assignment problem in determining the allocation of couriers in the case of delivering goods at PT. Shopee Express Soreang Kota Parepare Hub. The Hungarian method is used to determine the optimal allocation of couriers based on the efficiency of the delivery time of goods so that the total distribution time can be minimized. In its implementation, adjustments were made to the procedures of the Hungarian method to accommodate unbalanced data conditions. Validation of assignment results is carried out using Program for Operations Management-Quantitative Methods (POM-QM) software for Windows to ensure that the solutions obtained through manual calculations match the system's computational results and actually produce optimal values. The results showed that the total average delivery time before optimization of 53.45 minutes could be reduced to 41.80 minutes after the application of the Hungarian method, resulting in a time efficiency of 11.65 minutes. Validation using POM-QM for Windows shows results consistent with manual calculations. Thus, the Hungarian method has proven to be effective in improving the efficiency of courier assignments and minimizing the delivery time of goods.
