Abstrak: There are six main steps in this research, which is surveying UKM Sawargi, preparing the taro flour and grated taro, making the taro dodol, storaging the taro dodol in room temperature, analyzing the sample, and settling the shelf life of taro dodol. The analysis is divided into five parameters, which is aw, the penetrometer result, the acceptance sensory test of product in term of rancidity and texture, and the growth of mold. The result of this research is that taro dodol which made using taro flour is having longer shelf life compare to taro dodol which made using grated taro. The difference of shelf life is about 11 days, which is taro dodol from taro flour last for 32 days and taro dodol from taro grated last for 21 days. Meanwhile, the initial shelf life of taro dodol produced by UKM Sawargi is 10 days. The spoilage of taro dodol is indicated with the growth of mold which is visually detected. It makes the most critical parameter for the spoilage of taro dodol is aw with the limit of aw is 0.80.

Abstrak: Drying process had become an effort to process taro corms as the raw material for industry. The main problems of taro corms post-harvesting before drying process were the pre-treatment and how to process the slice of taro corms. The objectives of this research are to study the dehydrator temperature effect and pre-treatment before drying process of taro corms using Sunbeam Food Dehydrator DT5600 (55 ᴼC and 75 ᴼC) to the dried taro corms quality, also to assess the performance of Sunbeam Food Dehydrator DT5600. The slice taro corms had 2 mm thickness. There were four treatments before drying, the first was no treatment as control, the second was blanching treatments of the slice of taro corms within the 7 liters water at temperature of 80 ᴼC for 15 minutes, the third was blanching which followed by the soaking within the 10% concentration of sodium chloride solution, and the fourth was same as third treatment which followed by blanching using 2 g/kg of sodium metabisulphite at temperature of 80 ᴼC for a minute. The result showed that taro which is dried at drying temperature of 75 ᴼC more efficient than that of dried at drying temperature of 55 ᴼC. The drying rate and efficiency of taro drying were 43.84 %bk/jam and 17.38% respectively. Dried taro is categorized into super quality for first and second treatments, first quality for fourth treatments and second quality for third treatments. The pre-treatment of taro drying by using blanching and by the soaking within 10% concentration of sodium chloride solution is recommended to reduce oxalate of dried taro until 81.11%.

Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density.

The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
