Sweet potato (Ipomoea batatas L.) is a plant that needs full sun to grow and get optimum yield. It needs an engineering technology that is able to integrate plant and environment in order to overcome abiotic factors in Papua highland. This research aims to determine the growth, result and energy conversion efficiency conatined in the sweet potato by combining variety and different stake inclination angle. This research was conducted in Baliem valley of Jayawijaya district. The experimental design used was factorial group random design with three replications. The research result shows that to make plant more efficient in managing solar intensity in Papua highland, so it is advised to plant Cangkuang variety (broad leaf) and to use stakle with inclination angle of 60o and 90o.
