Abstract

In agriculture, irrigation is important, one of the factors that will ensure agriculture runs well is irrigation. Artificial irrigation can be a solution to this problem, but creating artificial irrigation requires quite a large cost. Therefore, Dinas Tanaman Pangan dan Holtikultura is helping farmers to develop a tertiary plot irrigation network covering an area of less than 1000 hectares. With so many applications coming to the Dinas Tanaman Pangan dan Holtikuoltura, the Fuzzy Analytical Hierarchy Process method could be a solution for determining irrigation development priorities. The results of the analysis used the Fuzzy Analytical Hierarchy Process with the criteria: Irrigation Area, Area of Rice Fields Served by Irrigation, Irrigation Development Costs, and Construction Time and alternatives: Sunggal Irrigation Area, Teluk Mengkudu Irrigation Area, Pantai Cermin Irrigation Area, Medang Deras Irrigation Area, Lima Puluh Pesisir Irrigation Area, Gunung Malela Irrigation Area, Nagori Silulu Irrigation Area, Juhar Irrigation Area, Sayur Matinggi Irrigation Area, Panyabungan Irrigation Area and Panyabungan Barat Irrigation Area, namely the Lima Puluh Pesisir area is ranked first in the priority of irrigation development in North Sumatra with a value of 0.852

Abstract

Ethnomathematics is one technique that explains the various cultural contexts associated with mathematics applied by a particular community. SilahiSabungan Monument is a monument that holds significant meaning for the Toba Batak community in North Sumatra, Indonesia. Through an ethnomathematical approach, this research explores and analyzes the relationship between the symbols and forms found at SilahiSabungan Monument with underlying mathematical concepts. The research method used is qualitative research. The results of this study indicate that the shapes and symbols at SilahiSabungan Monument are related to concepts of plane geometry. For example, shapes like rectangles, trapezoids, and others on the monument can be connected with concepts of plane geometry. This demonstrates the richness of mathematical knowledge within Toba Batak culture. This ethnomathematical exploration provides a deeper understanding of the relationship between culture and mathematics in the context of the SilahiSabungan Monument. This research makes an important contribution to expanding the insights and understanding of researchers and the community about ethnomathematics and the importance of preserving and respecting cultural heritage and traditional knowledge. Further exploration of ethnomathematics at SilahiSabungan Monument can provide new perspectives in understanding and appreciating the cultural and mathematical diversity in Indonesia.
