"Patchouli (Pogostemon cablin) is one of the important crop species in Indonesia, since over 80% of patchouli oil global market is produced in Indonesia. Pacthouli oil is the key ingredients for fragrance and aromatherapy products. Patchouli oil is extracted from the stems and leaves of pathouli plants. Therefore, it is important to improve Patchouli plant productivity and increase resources for sustainable patchouli cultivation. The suitability of abiotic factors in the growing environment of crops remarkably determines the success of crop production. This study aimed to assess and evaluate land suitability for plant growth and development of Patchouli (Pogostemon cablin) in Dilem Wilis, Bendungan District, Trenggalek Regency, Indonesia. Initially, a survey was conducted and then an analysis was done to classify the land suitability for crops cultivation. The research was conducted on 3 locations from May to July 2017 for land suitability and from July to November 2017 for Patchouli crops cultivation experiment. The results indicated that Location 1 had a land suitability of N class, implying that this location was not suitable due to its limiting factor of low IGO content (0.08 me/100 g). Meanwhile, both Location 2 and Location 3 showed similar land suitability class of S3s, tc, f, n signifying as less appropriate. The results of this study also indicated the influence of land suitability classes on plant growth however, the different classification (in this case S3 compared to N) did not demonstrate a correlation between land classes and oil yield and Patchouli alcohol, where the element Potassium was the limiting factor"

"Population of Flindersia pimenteliana (Maple Silkwood) in Indonesian Papua and Papua New Guinea is severely fragmented and experiencing a continuing decline due to habitat destruction and illegal logging. This species is very susceptible to environmental changes and at greater risk of extinction due to its small and fragmented geographic ranges and low abundance. Using maximum entropy (MaxEnt) method, the present study predicted the impact of climate change on the distribution of the species across its native distribution area. Elevation and 19 bioclimatic variables commonly used in species distribution modeling were used as predictors. Â The prediction model of the current potential distribution identified a total area of 156,214 km2 in Indonesian Papua and Papua New Guinea (18% of total land area) as suitable habitat for F. pimenteliana. Elevation and precipitation of the wettest, coldest and warmest quarters contributed most to the model. Based on the average of HadGEM2-ES and MIROC-ESM models, potential distribution projections under RCP8.5 scenario suggested a habitat gain of 16% for 2050 and 8% for 2070 in the species distribution. Whereas under RCP4.5, an average habitat gain of 7% was predicted for both 2050 and 2070. The newly suitable habitats were predicted to be found mainly in Southern and Western Highland of Papua New Guinea. Protection of these areas from habitat destruction and land use change is needed to assist F. pimenteliana find the most suitable climate for its survival."
