ABSTRACT   Rogi, J.E.X. et. al. 2007. The Suistability Land for Corn in the South Minahasa District. Eugenia 13 (3) : 320-326. Based on agri-climate and market prospective, corn is a potential comodity in the South-Minahasa District. From 215.000 ha of South-Minahasa District area, it has 18.437 ha harvest-area and in 2006 produced 52.747 tonnes corn. The above data showed that this district has a possibility to extend the corn planting area in suitable area. To find this suistability area for corn, a spatial data was composed based on soil and climate data using Geographic Information Systemm (GIS). Soil data consisted of texture, pH, C-organic, and cation exchange capacity (CEC), whereas climate data consisted of rainfall and air temperature. Spatial data in the form of land suitability map for corn in the South-Minahasa District was analysed using ArcViewer 3.2. software.   Keywords: Harvest area, soil and climate, spatial data, GIS, ArcViewer 3.2

Abstract

ABSTRACT This research was to study about some physical properties of angsana (Pterocarpus indicus) sapwood related in wood position to wood position in trunk (base, middle, and tip) and to environmental factors (temperature and humidity). It used a faktorial design in completely randomized block with combinations of 3 environmental condition and 3 wood position in trunk. These nine treatments are repeated three times. The results showed that moisture content, wood density, and volumetric shrinkage of angsana sapwood could be influenced by wood position in trunk (base, middle, and tip). The swelling property of angsana sapwood was not influenced by wood position in trunk but it was influenced by environmental factors. Key words : physical properties, sapwood, wood position, temperature, humidity
