Abstract

Tanaman kelapa sawit (Elaeis guineensis Jacq) merupakan komoditas perkebunan strategis yang memberikan kontribusi ekonomi besar per hektar secara global. Peningkatan kebutuhan dunia akan minyak sawit menuntut strategi produksi yang efektif, salah satunya melalui pemilihan bibit unggul. Pemilihan bibit yang tepat menjadi faktor penting dalam mendukung produktivitas dan keberhasilan budidaya. Beberapa jenis bibit unggul yang umum digunakan oleh petani antara lain Dumpy, Yangambi, SP540, dan DxP 540 NG. Untuk mempermudah proses pengambilan keputusan dalam pemilihan bibit terbaik, penelitian ini menerapkan metode MOORA (Multi-Objective Optimization by Ratio Analysis), sebuah metode pengambilan keputusan multikriteria yang sederhana, fleksibel, dan efektif dalam menangani banyak kriteria secara simultan. Penelitian ini menggunakan delapan kriteria evaluasi bibit kelapa sawit dengan lima alternatif jenis bibit. Setiap kriteria diberi bobot berdasarkan hasil wawancara dengan ahli, kemudian dinormalisasi dan dihitung nilai preferensinya (Yi) untuk menentukan peringkat. Hasil analisis menunjukkan bahwa bibit terbaik adalah DxP 540 NG dengan nilai Yi sebesar 0,426, diikuti oleh turunan SP540 (0,357), turunan Yangambi (0,320), DxP Langkat (0,315), dan DyP Sungai Pancur I (Dumpy) (0,315). Hasil ini membuktikan bahwa metode MOORA dapat digunakan sebagai sistem pendukung keputusan yang membantu petani dalam memilih bibit sawit terbaik secara objektif dan sistematis. Pendekatan ini juga dapat dikembangkan lebih lanjut dalam konteks pengambilan keputusan pertanian lainnya yang melibatkan banyak kriteria.

Abstract

In learning, students are required to understand the concepts of problems and visualize the objects of mathematical learning discussions. However, in reality, students face difficulties in understanding and visualizing the objects discussed; learning media can help solve the problems faced by students so that the learning process is no longer conventional, which causes students to be passive. This research aims to determine whether there is an effect of GeoGebra learning media on the Discovery Learning model on students' understanding of mathematical concepts. This research uses a quasi-experimental quantitative method that tests the cause and effect between variables. The study was conducted in class XI MIA MAL UINSU as the population, with sampling carried out by randomizing classes. The sample for this study consisted of students from class XI MIA 1 as the control class and XI MIA 2 as the experimental class. Each class consists of 39 students. The instrument used is a mathematical concept understanding ability test in the form of an essay, consisting of a pretest and a posttest. The data collected were then tested using a t-test. Based on the t-test calculations with α= 0.05, the significance value obtained is 0.000, thus 0.000 < 0.05. It can be concluded that GeoGebra learning media has an effect on the Discovery Learning model on students' concept understanding. The research results regarding the impact of learning media on students' concept understanding indicate that teachers can implement this learning media in their teaching.

Abstract

This study explores ethnomathematics embedded in the forms and motifs of the Payung Mesikhat, a cultural symbol of the Alas Indigenous community in Darul Amin Village, Southeast Aceh Regency. A qualitative approach with an ethnographic method was employed to uncover the mathematical meanings inherent in the geometric elements of this traditional umbrella. Data were collected through observation, in-depth interviews with cultural figures and artisans, and visual documentation. To analyze the geometric shapes identified, GeoGebra was used as a tool for visualization and mathematical representation. The findings reveal that the Payung Mesikhat embodies various mathematical concepts, such as reflection symmetry, rotation, geometric transformations, patterns, and repetitions, each carrying philosophical significance in the Alas culture. With the aid of GeoGebra, these concepts can be represented visually and interactively, thereby supporting contextual mathematics learning based on local culture. This study is expected to enrich locally grounded mathematics teaching materials and strengthen cultural preservation through educational approaches.
