Judul: Spatial Modelling on Susceptibility of Fires in Peatland, a Case Study in District of Bengkalis, Riau Province
Abstrak: Peatland is one of ecosystem types in Indonesia which plays important role in maintaning terrestrial carbons, hydrological cycles and preserving biodiversity. Recently, most of the peatland (forest and non forest) has been degraded. One of the causes of degradation is fire. This study was conducted to establish a model and map of peat fire risk in District of Bengkalis, Riau Province. The model was established by hotspot distribution as an indicator of fire occurrences. Environmental and infrastructure aspects were employed as supportive factors to fire. Factors which were used to describe the environmental aspect were landcover and vegetation types, peat depth, and greenness level of vegetation. Factors of infrastructure aspect were the distance of fire occurrences with road network, distance to the river network and to the center of villages. Weighting and scoring were the basis of model development using the method of Complete Mapping Analysis (CMA). The model suggested that peat fire is more strongly affected by infrastructure aspect when compared with environmental aspect with the weight of 0.658 and 0.342 respectively. This explains that fires occurred were triggered more by human factor rather than environmental factor. The chosen factor of infrastructure aspect is distance from occurenced fires of road network. The selected environmental aspects were landcover and vegetation types, peat depth and greenness level of vegetation. Seemingly, the distance of river and center of villages may not be the supportive factors of peat fires, as showed by the presence of hotspots in which found mostly in the area far from the river and village center. The model can explain the condition of average of fire occurrences with the validation of 80%. Therefore, it can be used as the referrence in developing and establishing of polic ies for peat fire prevention and suppression.

Abstrak: Bengkalis is one of districts which is vulnerable to forest and peatland fires in Riau due to land use change. This research aims to compare the observation climate data of Indonesian Agency for Meteorological, Climatological and Geophysics (BMKG) and global climate data from Climatic Research Unit (CRU) satellite as factors that affect the incidence of forest and peatland fires, analyze the distribution of forest and peatland fires in Bengkalis, and analyze the correlation between the elements climate (rainfall, maximum air temperature, and average air temperature) of CRU satellite and hotspot as an indicator of forest and peatland fires in Bengkalis. The result of the research revealed that climate patterns of CRU satellite in line with climate patterns of BMKG observations.. Spatial distribution of hotspots, 1998, 2002, 2004, 2005, 2006, and 2009 had the highest number of hotspots. Most hotspots are in the peat soil types Hemists/Saprists (60/40), very deep and on land cover shrub swamp. The maximum air temperature and average air temperature significant (p-value <0.05) to the number of hotspots while the rainfall did not significantly affect the number of hotspots. The best model also showed the absence of a suitable model to describe the relationship between elements of the climate and the number of hotspots.

Abstrak: Egg is an animal origin food product which has high nutritional value especially protein. Cholesterol content of eggs is only found in egg yolk, on the other hand albumen does not countain cholesterol at all but high content of protein, so it can be used as a free cholesterol-protein sources. The application of albumen as egg instant drink effervescent tablet can be an alternative of protein source for people who need free-cholesterol diet. It can also become an egg product diversification.
