Temporal Variation of Soil Surface Temperature in Dalugha (Cyrtosperma Merkusii (Hassk.) Schott)(Hassk.) Swamp Habitat

Abstract

This article describes about the changes of the temporal variation of the soil surface temperatur daily in swamp habitat Dalugha in Sangihe regency. This study is a part of Dalugha habitat research, associated with the development of this plant as a food alternative. The study was conducted transects made the cut edge of the habitat area, ranging from mixed soil farms inward Dalugha clumps . Temporal changes in the temperature of the soil surface and its immediate surroundings of dalugha obtained through the mathematical modeling of the data result measurements at nine positions along the transect is logarithmic. The results showed that temporal changes in land surface temperature by measuring the position of the three examples have the same pattern, sinusoidal. The difference in the three examples shown by the differenting in the position of the average, lowest, highest, and the time of the incident the highest and lowest values
