Abstract

Toba Regency is one of the areas with potential for agroforestry land development. However, the existing potential has not been well identified regarding the distribution, profitability, and economic value of land in the study of meeting the living needs of agroforestry farmers in Toba Regency. This study aims to determine the potential of agroforestry land in Toba Regency, as well as a source of information for the Toba Regency government in order to develop agroforestry in its working area. The method used is direct observation method to the field and interview method to obtain information related to socio-economic data of farmers, types of land fill plants, as well as inputs and outputs of agroforestry land.

Forestry plants on the land, such as white teak (Gmelina arborea), pine (Pinus merkusii). Perennial plants, such as coffee (Coffea arabica). Multipurpose Tree Species (MPTS), such as candlenut (Aleurites moluccanus), mango (Mangifera indica), cocoa (Theobroma cacao), and durian (Durio zibethinus). Agricultural crops, such as corn (Zea mays) and pineapple ((Ananas comosus), as well as livestock rearing and fish farming were found. Based on profitability calculations, 15 existing lands are feasible to cultivate and develop with Net Present Value (NPV) and Equal Annual Equivalent (EAE) > 0 and Profitability Index (PI) > 1. Farmers income during 10 years of land management ranges from Rp. 7,450,000 to Rp. 162,719,500, where the largest income of farmers comes from coffee.
