Abstrak: A research to study the influence of additives and ensiling times on ramie leaves silage qualities for ruminant have been studied in vitro using completely and block factorial 3 x 3 designs. Three types of water soluble carbohydrate (WSC) and dry matter sources as additives (A1 = cassava meal, A2 = pollard and A3 = corn meal) and three ensiling times (B1 = 28, B2 = 35, and B3 = 42 days) have been investigated. The degradability of organic matter to form VFA and protein to form NH3 were measured according to General Laboratory Procedure (1966), while the rate organic matter fermentation was measured follow the procedure of Menke et al., (1979). Value of pH and protein degradability were measured follow procedure of Naumann dan Bassler (1997) and Carro dan Miller (1999). The variable of this research consist of physical characteristic and fermentation parameters, fermentability and digestibility of the silages by ruminant have been determined in vitro. In generally, physical characteristic of ramie leaf silage are green brown, lactic acid odor and softer texture. Ramie leaf silage with additive corn meal (A3) have breakage. pH parameters showed that A1 acidified the silages faster than the A2 ones (3,62 vs 5,13). High pH of A3 (7,35) treatment was caused by the rought texture of corn meal used in this experiment. The silages were categorized as fermentable and high digestible feeds for ruminants (NH3 > 8,89 mM, VFA > 94.88 mM). Production gas for 24 hours incubation rumen liquor and estimation of organic matter digestibility (OMD) after 6 weeks ensiling time were around 72% and 50%.

Abstrak: Ramie leaves silage qualities improvement by addition 20% W/W FS of absorbance and water soluble carbohydrates (WSC) sources prior to 42 days of ensiling time have been done in two experiments. Experiment-1 examined three types of the additives (cassava meal, pollard and coarse grinding corn) for their capacities to improve physical (color, odor, texture and spoilage), fermentative (pH, protein degradation, organic acid profiles) and utilities characteristics of the silages for ruminants (rumen fermentabilities and digestibilities) in vitro. The silages had bright greenish brown of color, lactic acid odor and firm textures, categorized as highly fermentable and digestible feeds (dry matter digestibility >72%). Compare to other additives, cassava meal produced better silage based on their physical chemical characteristics and drop silage pH faster than other additives. However, high butyric acid and protein degradation proportions in the silage were not seem in line to these data. Coarse grinding corn failed to do its function therefore produced poor silage quality. Second experiment was aimed to confirm the previous results. Five types of additives (cassava meal, pollard, fine grinding corn, rice bran, and cassava extract meal) of the same functions were examined. The results confirmed that cassava meal still produce better ramie leave silages than other additives. However, this time, all additives successes to serve their functions therefore produce good ramie leave silage qualities.

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.
