Abstract

Mathematical modeling plays an essential role in mathematics learning, particularly in developing students analytical and problem-solving skills. Linear programming, as one of the core topics in optimization, often presents conceptual difficulties for students when linking abstract mathematical formulations to real-world problems. This study aims to analyze learning strategies for teaching linear programming through the implementation of mathematical modeling to improve students conceptual understanding and reasoning abilities. A descriptive qualitative approach was employed, focusing on literature review and classroom observations related to the used of mathematical models in teaching linear programming. The findings show that incorporating modeling steps-such as problem identification, variable formulation, and interpretation of result-helps students comprehend abstract mathematical ideas more effectively. Moreover, the integration of mathematical modeling encourages active learning and promotes students engagement in solving contextual problems. In conclusion, the use of mathematical modeling as a learning strategy provides a meaningful framework that enhances understanding, crirical thinking, and problem-solving skills in linear programming instruction.

Abstract

The transportation of goods and services is a strategic issue in logistics systems, particularly in the palm oil industry. One of the key distribution optimization challenges is the Capacitated Vehicle Routing Problem (CVRP), which involves determining optimal distribution routes while considering vehicle capacity constraints. This study aims to identify the shortest distribution routes for transporting fresh oil palm fruit bunches from collection points to the palm oil mill, with the goal of minimizing total vehicle travel distance. A heuristic approach using the Saving Matrix method and a metaheuristic approach using a Genetic Algorithm were applied separately to two regions: Block P and Block Q, each consisting of 14 collection points with daily distribution schedules. The performance of both algorithms was analyzed and compared in the context of region-based distribution.The results show that the Genetic Algorithm yields more optimal solutions than the Saving Matrix, reducing the total travel distance by 33.92% in Block P and 32.81% in Block Q. In comparison, the Saving Matrix achieved reductions of 38.72% in Block P and 35.25% in Block Q. These findings indicate that the Genetic Algorithm performs better in solving CVRP for the distribution of fresh oil palm fruit bunches and can serve as a foundation for developing more efficient distribution systems using heuristic and metaheuristic approaches

Abstract

Penelitian ini bertujuan untuk memproyeksikan penduduk Provinsi Sumatera Selatan menggunakan metode aritmetika dan metode geometri. Data yang digunakan adalah data penduduk pada tahun 2010 dan 2015. Hasil proyeksi penduduk Provinsi Sumatera Selatan pada tahun 2020 menurut metode aritmetika sebesar 8.722.436 jiwa, sedangkan menurut metode geometri sebesar 9.591.379 jiwa. Berdasarkan perhitungan Mean Absolut Percentage Eror (MAPE), metode terbaik untuk proyeksi populasi Provinsi Sumatera Selatan pada tahun 2030 adalah metode geometri dengan hasil proyeksi sebesar 8.181.701 jiwa. Rasio ketergantungan populasi Provinsi Sumatera Selatan pada tahun 2030 sebesar 53%, artinya 100 orang usia produktif menanggung 53 orang usia non-produktif.

Abstract

This study attempts to build a new model for information service financing schemes by considering utility functions to measure heterogeneous consumer satisfaction. This model was developed by involving a combination of reverse charging, demand response, and heterogeneous incentive models, and considering the quality of user service measured by a quasi-linear utility function against the information service financing scheme. The incentive financing scheme is applied to a local data server, including traffic during peak hours and off-peak hours. This internet incentive financing model is solved using the LINGO 13.0 application. Furthermore, the development model for incentive financing for information services based on demand response and bundling in the information service financing scheme is subjected to sensitivity analysis with the aim of identifying parameters that affect model performance. Based on the analysis that has been done, the results of this study indicate that the new model in the incentive financing scheme for information services with a quasi-linear utility function involving a combination of reverse charging, demand response, and heterogeneous incentive models produces an optimal solution in a fixed cost financing scheme for data traffic usage during peak hours and off-peak hours.

Abstract

Waste constitutes a substantial problem in urban and residential locales, as the volume of refuse escalates in tandem with population increase, deteriorating community quality of life. One solution to this problem is to provide temporary waste disposal sites (TWDS). This research discussed optimizing TWDS in the Sukarami Subdistrict, Palembang City, which consists of seven villages. The current TWDS in the Sukarami Subdistrict is irregular, with some sites located close together and others far apart. The optimization problem is solved by formulating the set covering problem (SCP) model, namely the set covering location problem (SCLP), the p-Median problem, and the Bender’s decomposition model. All models were solved using the general algebraic modeling system (GAMS) software. The research introduces a Bender’s decomposition model based on the SCLP model. The Sukarami Subdistrict has 29 TWDS located in only five villages. Using the SCLP and Bender’s decomposition models, the study identified 19 optimal TWDS in the Sukarami Subdistrict. Based on the solution of the p-Median problem, there are seven TWDS that can meet each village’s demand. This study recommends the optimal TWDS obtained from the Bender’s decomposition model. Additionally, two TWDS are recommended to be added, each in Sukodadi and Talang Betutu villages.

Abstract

Permasalahan mitra dalam kegiatan pengabdian ini meliputi pengelolaan sampah sekolah yang belum berjalan secara optimal serta belum dimanfaatkannya bank sampah sebagai bagian dari proses pembelajaran, khususnya pada mata pelajaran matematika. Pembelajaran matematika mencakup materi operasi hitung, pengukuran, dan penyajian data. Kegiatan pengabdian ini bertujuan untuk menerapkan bank sampah sebagai media pembelajaran matematika berbasis lingkungan di SD Negeri 8 Indralaya Utara. Metode pelaksanaan yang digunakan meliputi observasi, sosialisasi kepada siswa mengenai pentingnya bank sampah di lingkungan sekolah, pendampingan pembelajaran matematika yang terintegrasi dengan bank sampah, serta evaluasi melalui pretest dan posttest untuk mengukur peningkatan pemahaman siswa. Hasil kegiatan menunjukkan adanya peningkatan pemahaman konsep matematika siswa, yaitu pada materi luas meningkat sebesar 20,68% dari 62,07% menjadi 82,75%, materi volume meningkat sebesar 24,14% dari 62,07% menjadi 86,21%, dan materi statistika sederhana meningkat sebesar 19,23% dari 76,92% menjadi 96,15%. Dengan demikian, pemanfaatan bank sampah sebagai media pembelajaran matematika berbasis lingkungan terbukti efektif dalam meningkatkan hasil belajar siswa sekaligus mengedukasi siswa peduli terhadap lingkungan.
