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%.

Judul: Evaluasi Kualitas Nutrien Silase dan Hay Daun Rami dalam Ransum Komplit untuk Ruminansia secara In Vitro
Abstrak: A research to evaluate the effect of ramie leaves silage and hay on ruminant complete mixed ration (CMR) on nutrient content, fermentability, and digestibility by in vitro method have been conducted. There were 7 CMR treatments i.e. P0 (control ration) = 50% napier grass + 50% concentrate, P1 = 30% napier grass + 20% ramie leaves silage + 50% concentrate, P2 = 20% napier grass + 30% ramie leaves silage + 50% concentrate, P3 = 10% napier grass + 40% ramie leaves silage + 50% concentrate, P4 = 30% napier grass + 20% ramie leaves hay + 50% concentrate, P5 = 20% napier grass + 30% ramie leaves hay + 50% concentrate, and P6 = 10% napier grass + 40% hay + 50% concentrate. Both ramie leaves silage and hay increased the CMR digestibility and nutrient content, except the crude fiber. Control ration had a higher crude fiber than silage and hay. The CMR which contain ramie leaves silage had higher nutrient digestibility compared to the other rations. Fermentability of CMR was measured by ammonia concentration, VFA, and gas production. Rations which added with ramie leaves hay (P4 – P6) had a higher gas production whereas rations added with ramie leaves silage (P1 – P3) had a higher rations VFA concentration and gas production compared to P0. Ammonia concentration of rations added with preserved ramie leaves were lower than control, however ammonia concentration in all treatments were in optimal range. Acetate proportion was higher in CMR which contain ramie leaves hay than CMR which contain silage although the nutrients digestibility were lower. Adding ramie leaves silage in rations resulted higher propionate and butyrate proportion than control and rations which added with ramie leaves hay. Either silage or hay ramie leaves can be used up to 40% as napier grass substitute in ruminant CMR. Keywords: Hay, ramie leaves, ruminant, silage

Judul: Etno-ornitologi Burung Kancilan Flores (Pachycephala nudigula nudigula Hartert 1897) pada Masyarakat Lio di Taman Nasional Kelimutu
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.
