Abstract

Pergerakan Lutung budeng (Trachypithecus auratus) didaerah habitat terfragmentasi TamanNasional Bromo Tengger Semeru, Jawa Timur, Indonesia. Pergerakan lutung budeng didaerah habitat terfragmentasi diamati dengan metode transek. Hasil kajian menunjukkan bahwaada empat kelompok masing masing beranggotakan 12 (grup A), 16 (grup B), 15 (grup C) dan12 lutung (grup D). Penelitian yang dilakukan disekitar hunian penduduk, jalan, hutanterdegradasi dan jalan-jalan setapak mengindikasikan bahwa lutung dalam aktivitas hariannyamemerlukan waktu 32,82% diantaranya digunakan untuk makan, 30,97% untuk istirahat dansisanya 31,79 untuk pergerakan perpindahan. Lutung dalam aktivitasnya 50,53% menggunakanwilayah puncak kanopi tumbuhan, 41,99%menggunakan kanopi tumbuhan bagian tengah danhanya 2,49 % yang menggunakan kanopi bawah.

Abstract

First year re-monitoring conducted in 2009 through measuring the entire individuals that have been given numbersand giving new numbers to individuals with stem diameter more than 5 cm. The result of re-monitoring indicatesthat the numbers of populations and species increased, but not significant. Mortality rate observed 7 individualsper hectare (about 1.20 %); whereas natality rate observed 25 individuals per hectare (about 2.52 %), which isregarded as low. Basal area observed in 2008 was approximately 26.55 m2 per hectare and it increased to about27.34 m2 per hectare in 2009. Total number of individuals in 2009 was 595 individuals from 119 species, 86genera, and 44 families with diversity index of 3.60 (H’). Elaeocarpus petiolatus (Elaeocarpaceae) and Planchoniavalida (Sapotaceae) are new additions. Altingia excelsa is still the dominant species.Keywords: Forest dynamics, rasamala permanent plots, Bodogol, GPNP

Abstract

The animal obtains energy from foods. Apparent Metabolizable Energy (AME) is used to determine metabolizableenergy value of bird’s food. The objective of this research was to evaluate Apparent Metabolizable Energy (AME)value in Blue-crowned hanging parrot (Loriculus galgulus L., 1758), fed with corn mashes, oat mashes, dan pollardmashes. This research consisted of two experiments, which were 1 week of preliminary study and 8 weeks of datacollection. Studies were carried out with six Blue-crowned hanging parrots, two males and four females. The birdswere kept individually in metabolism cage (70 x 43 x 52 cm). The birds were treated with 3 different energy sources,corn-based diet (P1), oat-based diet (P2), and pollard-based diet (P3). The diets were then offered to the birds adlibitum in the form of mashes. Variables observed include dry matter consumption and Apparent MetabolizableEnergy (AME) value. From the calculation, AME of birds that fed with pollard mashes was higher compared to cornand oat mashes as well. In P1, AME value of birds was 43.64 cal/g with 93.90% of metabolic efficiency. While, inthe P2 and P3, AME value were 43.86 cal/g and 39.07 cal/g with number of metabolic efficiency 91.75% and94,58% respectively.Keywords: nutrition, pollard, oat, corn, AME, metabolic efficiency

Abstract

Tree architectural model is basically a tree construction as a result of meristematic growth pattern. Tree architectureis closely associated with water and soil components, i.e. rainfall, throughfall, stem flow, infiltration, surface run-off,and erosion. For Altingia excelsa (Rasamala) plots, the results showed that the daily average of the rainfall intensityobserved was 9.67 mm, stem flow 0.03 mm, canopy throughfall 5.43 mm, infiltration 0.51 ml/mm2/second,surface run-off 3.45 mm, and erosion 5.66 kg/m2. For Schima wallichii (Puspa), the daily average of rainfall was9.67 mm, stem flow 0.04 mm, canopy throughfall 4.02 mm, infiltration 0.49 ml/mm2/second, surface run-off 8.18mm, and erosion 12.71 kg/m2. Compared to A. excelsa, S. wallichii significantly had larger values in someparameters measured, i.e. stem flow, surface run-off, and erosion, indicating that on land sopes of 70% of theMount Gede Pangrango National Park, individual plants of S. wallichii seemed to be well adapted. However,individuals of A. excelsa possessed a more spreadly branching model, larger vertical width, denser canopy, andskewed bark channels capable for slowing down the stem flow and canopy throughfall. Consequently plants of A.excelsa would generally be able to hold and conserve water and soil better than S. wallichii plants.Keywords: Tree architectural model, stem flow, throughfall, surface run-off, infiltration, erosion

Abstract

A phytosociological study has been conducted in the south-east slope of Mount Salak, Sukabumi, West Java.Vegetation data were analyzed using 21 plots made of 30 m x 30 m which covered various habitat conditions. Atotal of ninety seven tree species (dbh. ≥ 10 cm) were recorded belonging to 72 genera and 39 families. The mostdominant families occurred in the study area were Fagaceae, Hammamelidaceae and Euphorbiaceae, followed byTheaceae, Meliaceae and Sapindaceae. The dominance of those families was apparently from the contribution ofthe most dominant species Altingia excelsa and the other species such as the Schima wallichii, Castanopsis javanica,Pometia pinnata, and Lithocarpus korthalsii. Spatial distribution of the vegetation is affected by altitude and/orhabitat slope which develop forest community patterns, such as lowland forest, lower and upper slope forests, aswell as lower and upper mountain forests. The distribution of tree species also follows this pattern, i.e certainspecies only occur on certain (specific) habitat type.Keywords: species ekology, Gunung Halimun-Salak National Park, phytosociology

Abstract

The exploitation of Napoleon fishery rates (Cheilinus undulatus) in the past year has been higher. Some areas inIndonesia are still doing the fishing business. Since the napoleon fish was registered in the IUCN red list &Appendix II of CITES, the export quota of 3,600 fishes per year was applied up to the year 2011. In order tosupport the evaluation size in the water bodies around Sinjai and Bone of the determination of napoleon fishprotection status, this study aims to determine fish population South Sulawesi. The method used was SnorkelingVisual Census (SVC). The results obtained indicate napoleon fish abundance is low (0 to 4 individuals/ha). Highestabundance of napoleon fish was found in Lapoipoi & Batanglampe, however none in three locations, i.e., Larearea,Pasiloange and Malambere. It is suggested that protection to species & its habitat is done in four locations wherethe napoleon fish were found, especially in Lapoipoi & Batanglampe.Keyword: napoleon fish, density, Sinjai, Bone, South Sulawesi
