Abstract

Cockatoo (Cacatua sp.) is one of birds that is widely distributed in Indonesia and often kept as pet, thus threatening the Cacatua population in the wild. Environmental condition may affect the behavior of Cockatoo. Some unnatural behavior may arise due to living in the captive. Different cage conditions may result in different behavior performance in Cockatoo. Research on daily behavior at animal rescue sites at ASTI Bogor has never been conducted. This study aimed to analyze natural and stereotype behavior of Cacatua sp. at animal rescue center due to foreclosure, and analyze the relationship between cage condition and environmental factors. This study used focal instantaneous sampling, using eight individuals Cacatua sp. Cacatua sp. in ASTI performed natural behavior more than unnatural behavior, therefore ASTI can be a good place for animal rescue. The dominant natural behaviors were Resting (Re), Preening (Pr), Feeding (Fe), Locomotion (Lo), and Fighting (Fg), while unnatural behaviors were play, bite, abnormal vocalization, feather picking and aggressive. There are no difference in behavior between male and female, and also behavior in the morning and afternoon (p>0.05), but cage condition had a significant effect to daily behavior of Cacatua sp. (<0.05).

Abstract

Mount Ciremai National Park has a high ecological function as a major catchment and water source areas. The objective of this research was to obtain information on floristic composition and structure in the edge forest of Seda Block, Mount Ciremai National Park. To carried out the research, the method used in the analysis vegetation was quadrat transect at an elevation of 602-614 m asl. The results showed that species composition dominated by the families of Euphorbiaceae and Moraceae, consisting of 3 stratas of heading A to C where strata A occupied by Elaeocarpus sp. (40 m) and Ficus involucrata (30 m). Ficus involucrata has the widest heading cover on the observation plot. The condition of the forest quantitative structure generally demonstrates good conditions by forming a reversed J curve, as well as a relatively moderate diversity of plant species and there are no species of plant that dominate the forest edges.

Abstract

Probiotics are living microorganisms if consumed in sufficient quantities can be beneficial for health. One of the potential bacteria as probiotics is Lactobacillus plantarum NHC6 is a lactic acid bacteria isolated from pineapple juice. This study aimed to test the ability of L. plantarum NHC6 as a probiotic in pineapple juice. Probiotics were stored until four weeks under 4°C and 10°C which weekly is monitored data on the amount of microbes, pH, percentage of lactic acid, and total dissolved solids in fermented pineapple juice. The result shows, the shelf time for pineapple juice under 4°C has a lower microbial reduction time rather than the juice storage under 10°C. Probiotics shelf time predicted for 4°C storage was 28.32 weeks and for 10°C storage was 8.67 weeks after production. The changes in physical properties (pH, percentage of lactic acid, and total soluble solids) in 10°C storage is much faster than that off in 4°C, this happens because there is still metabolic activity by bacteria at that temperature.
Identifikasi Tumbuhan Penghasil Polen dari Madu Lebah Tanpa Sengat di Belitung: Identification of Plants as Pollen Source in Honey of Stingless Bee Heterotrigona itama and Tetragonula laeviceps from Belitung Setya Priambudi , Abyan; Raffiudin, Rika; Ratna Djuita, Nina

Abstract

Stingless bees forage to the flower for nectar and at the same time, pollen also trapped in the body hairs of the bees. Mostly pollen was concentrated into the pollen basket and transferred to the pollen and honey pot in the stingless bee nest. Pollen is male gametophytes of seed plants which have various of shapes, sizes, and ornamentations. This palynology study was aimed to identify the plants of pollen source that were found in honey of stingless bee Heterotrigona itama and Tetragonula laeviceps in Belitung and to analyze characteristics of the pollen. Pollen was extracted from honey and conducted the acetolysis and identification of the pollen in honey. We found 11 and 19 plant species as pollen soirce in the honey of H. itama and T. laeviceps, respectively. Pollen from Macaranga tanarius (23.72%) and Cocos nucifera (22.53%) were the two most dominant species on the H. itama honey. Pollen from Ageratum conyzoides (16.36%) are most often found in T. laeviceps honey. The most common pollen in honey of H. itama and T. laeviceps were from Arecaceae with a total of three species. Pollen from plants with tree habitus is most commonly found in honey of both species of stingless bees.
Pembersihan Isi Sel Akar dan Jenis Warna Tinta untuk Deteksi Cendawan Mikoriza Arbuskula: Clearing of Root Cell Content and Types of Ink Stain for Arbuscular Mycorrhizal Fungal Detection Sulfiah, Siti; Sukarno, Nampiah; Gunawan, Agustin Wydia

Abstract

Arbuscular mycorrhizal (AM) fungi form mutualistic symbiosis with root of host plant. Staining technique to detect AM fungi usually used hazardous chemical. The ink stain and vinegar were used as an alternative technique to replace trypan blue and lactic acid in root staining method. This study aimed to determine time for clearing root cell contents and ink stain type to visualize the best AM fungal structures within the root observed under light microscope. Pueraria phaseoloides var. javanica roots colonized by AM fungi were cut into 1 cm long, cleared in KOH solution and stained. Four clearing time were done vis 5, 10, 15 and 20 minutes, and four stains were used namely Shaeffer black ink, Parker Quink blue ink, blue stamp ink, and trypan blue. Twenty stained roots were taken randomly from each tratment, and observed. Root clearing process for 20 minutes showed the best result. Only Shaeffer black ink and trypan blue produced clear structure of external hyphae, internal hyphae, vesicles and arbuscules. Arbuscular structure stained only by Shaeffer black ink and trypan blue. This indicated that Shaeffer black ink could be used as an alternative stain to detect AM fungi within the root of host plant
