Abstrak: The objective of this research was to make the cookies from modified arrowroot starch which have high resistant starch content, so that it can be used as functional food which have low glycemic index. The research consisted of three steps: arrowroot extraction, starch modification, and cookies making. The extraction of arrowroot produced 15.69% starch. Starch modification by autoclaving-cooling cycles was run in 3 cycles with 15 minutes gelatinization period in each cycle. Then, modified arrowroot starch was used as main ingredient in the making of cookies. Cookies from wheat were also made as comparison. Physical properties analyzed were breaking strength, color degree, and water activity. Chemical properties analyzed were proximate analysis, starch digestibility, amylose content, starch content, resistant starch content, and total dietary fiber content. Glycemic index was also analyzed for cookies from modified arrowroot starch and cookies from wheat. Breaking strength of cookies as measured by Texture Analyzer XT-21 showed that the force required to break the cookies significantly decreased with substitutions of wheat with modified arrowroot starch. The use of modified arrowroot starch resulted in the increase of amylose content, total dietary fiber content, and resistant starch content of cookies. It also could reduce starch digestibility of cookies. The glycemic index of cookies from modified arrowroot starch was 31. This value was lower than glycemic index of cookies from wheat that was 44. This was because higher amylose content, total dietary fiber content, and resistant starch content and lower starch digestibility of cookies from modified arrowroot starch than cookies from wheat. It means that the use of modified arrowroot starch as main ingredient in the making of cookies can decrease glycemic index of cookies.

Abstrak: Food is one of the basic of human needs that have to be compiled with. Therefore, the government in Indonesia have organized it by the Laws of Food in 1996 Number 7. Laws of Food in 1996 Number 7 also organize about food security. Food security is one of the concept where most of people- individuals and families-citizens of the country could get their needs of food easily. Food diversification is one of the efforts to establish food security. And, one of the most important of food diversification concept is to diversify carbohydate sources. This research based on Presidential Regulation Number 22 Year 2009 and Ministry of Agricultural Regulation Number 43 Year 2009 for increasing food consumption diversification through balanced diet. Carbohydrate sources are not only from rice, but also from other crops like tubers. Tubers in Indonesia are very large amount and kinds. One of them is arrowroot (Maranta arundinaceae Linn.). Many people have known about arrowroot but the research of arrowroot utilizations are still lack. So, it`s so important to make it in research. The purpose of this research was to get the most appropriate formulation of arrowroot starch and torbangun flour cookies as micronutrients sources. The experimental design used in this study was a randomized block design. The level of adding torbangun flour to arrowroot starch was 0%, 10%, 15%, and 20%. The study showed that the 10% adding of torbangun flour was the most organoleptic level. The addition of torbangun flour also could be the sources of micronutrient of calcium (376.60 mg/100g) and iron (3.83 mg/100g). It is recommended that the people should eat 100-gram cookies per day to fulfill the nutrient requirement.

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 habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. 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.
