The land snail fauna of the largest tropical montane forest in Java, the Gunung Halimun Salak National Park (GHSNP), was surveyed during the dry season (June-July) in 2015, concentrating on four park’s resorts, i.e. Cikaniki, Mt. Botol, Cisarua (Halimun area) and Cidahu (Salak area). In total, 399 specimens representing 43 species were collected. Prior to the surveys, 48 land snail species were known from the GHSNP. Fifteen new records for the GHSNP were discovered so 63 species are now known to inhabit the Park. This number represent 25% of the total land snail fauna of Java. 21 of the species found in GHSNP are endemic to Java. The species richness of the plots in GHSNP was correlated with soil pH and the composition of the land snail communities was correlated with elevation, annual mean temperature, and amount of deadwood.
Bufonid toad genus Leptophryne comprises three species; L. borbonica, L. cruentata, and L. javanica. These three species occurred in Java Island. Two out of three species, L. cruentata and L. javanica, are endemic and classified as critically endangered (CR) and endangered (EN), respectively. Leptophryne javanica recently described in 2018, and it is separated from L. cruentata by having distinct morphology, molecular and call characteristics. Both L. cruentata and L. javanica share the same habitat type (i.e. mountain forest, waterfall, rocky stream). Until early 2000, these two endemic Leptophryne were considered restricted to Mt. Gede. From 2000 to 2018, these species were also recorded in Mt. Halimun, Mt. Ciremai, and Mt. Slamet. These new localities indicate that there is potential distribution outside previously known locations. This study aims to predict the potential suitable habitat of endemic Leptophryne (L. cruentata and L. javanica) and identify the most important environmental variables on its distribution. MaxEnt modelling was applied to generate a potential suitable habitat distribution map. Twelve presence data were used for the model consist of 10 coordinates in Mt. Gede Pangrango, one in Mt. Ciremai, and one in Mt. Slamet. To build the model, 21 environmental variables were utilized: land cover, altitudinal and 19 variables of precipitation and temperature along with the species presence data. The result shows there is suitable habitat outside the known locations, consist of 14 patches in western Java, five in central Java and four in eastern Java. The most potential is in the mountainous area at southern Bandung. The lowest temperature fluctuation, highest elevation, lowest mean temperature during the warmest season, and better land cover provides the best habitat suitability. Further study is required to verify these potential distributions based on the modelling result.
Forest fire is a massive threat towards tropical forest causing various negative impacts to nature and human being. Forest fire often leads to alteration of forest structure and its functions. This study of tree growth after forest fire was conducted using a model simulation. The model was performed at the individual level of plant community and built to analyze the potential of tree growth and its scenario for post-fire recovery. Five important tree species from montane forest of Mount Ciremai were chosen to build the model based on four main parameters i.e. plant growth rate, diameter at breast height (DBH), tree-to-grass competition and tree-to-tree competition. The scenario of postfire recovery was performed by replanting similar species with 5 cm DBH seedling. Prediction from our model showed that most of the chosen species would recover to its pre-fire condition after 37 -50 years. Considering the limitation of competition after re-planting, it was suggested to minimize tree to tree competition and applied silvicultural treatments to maximize tree growth and tree community recovery.
This study aims to find out about educational professionalism in terms of religion, philosophy, psychology, and sociology at SMKN 1 Kota Tasikmalaya. This research uses qualitative research with descriptive research type, by describing the professionalism of education in this case teachers as educators. The results of observations and interviews which are described in the form of written narratives as a form of findings in the field. In order for a quality and relevant learning process, up to date, human resource needs (manpower) well applied, the conclusion of the findings illustrates that the implementation of educational professionalism through a review of religion, philosophy, psychology, and sociology has been well implemented. This is shown that the school climate has paid attention to the tendency of globalization which has consequences for changes in the learning paradigm, namely from the "old" paradigm to the "new" paradigm. Understanding globalization can have an impact on the progress of world civilization, which is an important lesson for all school members who always need to prioritize professionalism and be responsive to every problem in schools, and be innovative towards social changes in education that are always dynamic through the development of teachers and education staff, design operational curriculum, class management design, and graduate tracing design.
The presence of birds in the airport area is a danger to aviation. Collisions between aircraft and birds have potential to damage the aircraft which is very detrimental to the airline financially and fatal accident. The International Civil Aviation Organization (ICAO) provides recommendations to all member countries to take preventive and anticipatory actions to control and reduce bird populations by conducting Risk Assessment and Habitat Management so that airport is not becoming attractive places for birds. This research aims at conducting a Risk Assessment on bird species in the airport environment, a case study at Soekarno-Hatta Airport. Hazasd Risk Assesment is carried out using two methods, namely the based method (Sowden et al. 2007) and the modified method based on location, flight altitude and number of birds popullation. The results of the analysis of the two methods indicate that there are no bird species with a very high risk of bird strike hazard at Soekarno-Hatta Airport. Based on the modified method, there are five species of birds with a high risk of bird strike danger, namely Rice Heron (Ardeola speciosa), Buffalo Egret (Bubulcus ibis), Silver Egret (Ardea intermedia), Red Heron (Ardea purpurea), and Bluwok Heron (Mycteria cinerea). Meanwhile, based on the approach (Sowden et al. 2007) there are three types of birds that have a risk of causing significant danger in the event of a birdtsrike, namely the Bluwok Heron, the Gray Heron (Ardea cinerea), and the Asian Snakehead (Anhinga melanogaster).
