Abstract

Vegetation cover is closely related to temperature that causes the variation of temperature magnitude with a fairly high intensity. Meanwhile, surface temperature is affected by vegetation. This study aims to determine the type and the extent of vegetation distribution based on temperature zones using Landsat 8 imagery. It was carried out in the protected forest of South Dolo Sub-district, Sigi Regency, Central Sulawesi, Indonesia. The methodology includes unsupervised classification method and survey method. Data collection phase employs the techniques to obtain primary and secondary data, and data processing. The results indicate the relationship between vegetation cover and the changes in surface temperature, and the effect of the vegetation cover on the surface temperature of the protected forest in South Dolo Sub-district. The Landsat 8 image classification shows this area is dominated by tree with temperature of 17.3?22.2 ?C, while the temperature of shrubs /open land is 22.3?31.7 ?C. The relationship between temperature and vegetation cover is reflected from the value of y = 25.687 ? 10.043x in trees and y = 2.980 + 3.000x in shrubs/open land with a coefficient of determination/R2 = 1, which indicates the extent of the area of vegetation cover (y) is affected by surface temperature (x).

Abstract

The current high population rate leads to inevitable, greater demand for energy. In fact, most urban communities depend on oil and gas as the energy source for daily usage while the communities in rural and remote areas preferably use woods as fuel. The search for alternative source to reduce the dependency on the availability of fuelwood has been done by utilizing agricultural waste, industrial waste and domestic waste, including coconut shells and sawdust. These wastes can be processed into briquettes as potential solid fuel. The present study aims to investigate the quality of briquettes made from a mixture of coconut shells and palapi sawdust. It was done in May to July 2016 at the Mechanical Engineering Labolatory, Tadulako University. A completely randomized design (CRD) was employed, with three treatments: A (100% coconut shell charcoal), B (85% sawdust + 15% coconut shell charcoal) and C (85% coconut shell charcoal + 15% sawdust). The parameters included density, moisture, volatile matter, ash, and fixed carbon. The results showed the average moisture, ash, fixed carbon, volatile mater, and density of charcoal briquettes were: 4.62?4.99%, 4.51?5.55%, 29.63?53.17%, 36.94?59.88% and 0.48?0.7g/cm3, respectively. It indicates that the mixture of coconut shell and sawdust has a very significant effect on ash content, volatile matter, fixed carbon and density, but insignificant effect on water content.
