Optimisasi Pemilihan Jenis Tanaman dalam Program Pengembangan Tanaman Pangan Menggunakan Metode AHP

Abstract

Mayang Sari Village, Merbau District, Meranti Islands Regency, Riau Province, recently has an active youth program, namely the Karang Taruna organization. Karang Taruna is a forum for coaching, development, and empowerment in an effort to develop productive economic activities by utilizing all the potential available in the environment, both human resources and existing natural resources. One of the programs of the Mayang Sari Village Youth Organization is improving the community's economy in the agricultural sector as additional income through pilot project in food crop development by utilizing available empty land. Alternative food crops chosen based on local land suitability include field rice, corn, sweet potato, and cassava. The types of food plants are selected by considering the criteria such as land area, plant care, harvest time, and marketing. The aim of this research is to apply a decision-making method in selecting alternative food crops which is used as plantation pilot project by the Mayang Sari Village Youth Organization. The method implemented in selecting these alternatives is the Analytical Hierarchy Process (AHP). The AHP method is a method of making an optimal decision on a problem in determining priority choices from the available alternatives. The AHP step begins by creating a hierarchical structure of the problem being studied. Then a pairwise comparison matrix that is used to form relationships in the structure is created. In this pairwise comparison matrix, the weight of each criterion is found by normalizing the pairwise comparison matrix. The maximum eigenvalues and normalized eigenvectors are obtained from the matrix. In the process of determining hierarchical weighting factors and evaluation factors, consistency tests are carried out with a consistency ratio (CR) of less than 10%. With the steps of the AHP method, the priority food crops are obtained consecutively, namely corn (0.322), sweet potato (0.308), cassava (0.212), and field rice (0.158).
